In the early days of motorsports, a race car was just that—a car. There were no computers to monitor engine performance, no GPS equipment to help drivers find their way around a track, and certainly no Wi-Fi with which to stream the highlights of a race in real-time. 

But times have changed. The modern race car is more computer than a machine. The addition of sensors has been integral to that change. 

In this post, you’ll see how these simple pieces of technology have had an enormous impact on how racers drive:

1. EGT Sensors

EGT sensors are used to measure the temperature of exhaust gases. Exhaust gases are about twice as hot as the temperature at which water boils, so it’s essential to know how much heat your engine’s getting. 

Drivers need EGT sensors as they’ll also tell them if something in the engine is overheating and may even give them a warning before any damage is done. EGT sensors can also tell them when things get too hot in turbochargers—and alert them if that means trouble for their turbocharger.

2. The O2 Sensor

To control the fuel-air ratio, the O2 sensor measures the amount of oxygen in the exhaust and transmits that information to the car’s computer. For example, if the engine is running rich and needs more air, an O2 sensor will inform the computer to inject more fuel into your engine. If too much air comes out of your exhaust pipe, an O2 sensor will let the computer know that it needs less gas. That way, they’ll get a consistent amount of power out of every wheel’s turn.

3. Throttle Position Sensor (TPS)

A throttle position sensor (TPS) is a pin that measures the amount of air flowing into the engine. Pressing on the accelerator will tell the ECU how much throttle is applied. This is useful because if they want more power from the engine, they need more air to enter it. By measuring this through a TPS, the computer can ensure enough fuel enters the cylinders to run smoothly. Without one of these sensors, an ECU would have no way of knowing how much gas was required and when. The TPSs will have no choice but to guess based on other signals from various sensors over the car’s engine bay or chassis. If everything isn’t working properly, this could lead to some serious problems. 

In addition to measuring throttle position (which also tells whether or not you’re accelerating), TPSs measure intake airflow directly behind the car’s throttle plate when they accelerate hard enough for airflow values above zero mph. This means they’ll tell the driver what kind of sound waves are coming out from beneath their hoods based on their speeds and pressures during acceleration tests. This part of the evolution of the modern race cars helps engineers determine which parts might need replacing before another race.

4. Airflow Meter

The airflow meter is a sensor that measures the airflow in the car’s intake tract. It does this by measuring the pressure at various points of an engine’s airflow path and calculating the horsepower used. The airflow meter is made out of steel, plastic, and aluminum. It’s installed on most race cars as part of their intake manifold.

5. Exhaust Gas Recirculation (EGR) Valve

An EGR valve is one of the most important sensors on a race car. This controls the flow of exhaust gases into the intake manifold. This reduces the temperature of the combustion chamber and, in turn, reduces NOx emissions. It also increases efficiency by reducing unburned fuel. Depending on driving conditions like load or RPMs, drivers can adjust the EGR valve to allow more exhaust gas into their engine.

6. Manifold Absolute Pressure (MAP) Sensor

MAP sensors measure the pressure of the air entering an engine. This information is then sent to an electronic control unit (ECU), which determines how much fuel should be injected into the engine. It can also tell you when too much/too little air is coming into your vehicle. This can help boost performance or prevent damage from overheating.

7. Wheel Speed Sensors

You’ve probably heard the term ‘wheel speed sensor’ before, but what does it actually do? Wheel speed sensors have been used in race cars for years to measure the speed of the wheels. They determine how much traction drivers have on each wheel and help prevent them from spinning out. In addition to sensing how fast the tires are rotating, they monitor other factors such as acceleration and deceleration so that their car can respond accordingly.

Conclusion

Sensors play a critical role in modern race cars. Sensors monitor the car’s performance, health, and safety. The most critical sensors monitor vehicle performance by collecting data on speed, position, acceleration, and other parameters displayed on a computer screen or via an ECU (Electronic Control Unit). The future of cars will be exciting as sensors become more prevalent in production vehicles.

Motorsports used to be an “all-men-affair” until the mid-1950s. But the world of motorsports has continued to change drastically since the 50s. We’ve seen many female drivers in recent years competing professionally, and with the development of the sport, the scope of sports betting online is also rising. 

Pioneers such as Maria Teresa de Filippis, Michèle Mouton, Danica Patrick, and Susie Wolff laid the foundation for transforming the sport into what it is today. In this article, we celebrate some of the most iconic female figures to grace the world of motorsports:

Danica Patrick

Patrick holds the honor of being the only woman to win an IndyCar race in 2008 when she outraced Helio Castroneves by a little over 5 seconds at the Indy Japan 300. 

Patrick’s career resume is filled with many firsts. She is also the first woman to earn a pole position in the NASCAR Cup Series and finish highest in the IndyCar Series overall standings when she placed 5th in 2009. 

Desiré Wilson

Although Desiré Wilson never qualified for Formula 1 (F1), she remains one of five women to enter a Grand Prix. She missed out on the British Grand Prix in 1980 and failed to make it to Indy500 after three trials.

To this day, the South African native remains the only woman to win an F1 race of any kind after winning at Brands Hatch in the British Aurora F1 series.

Jamie Chadwick

In 2015, Jamie Chadwick won the British GT championship. She became the youngest and first female driver to win the title. 

The 24-year-old British won the inaugural W-Series championship and reclaimed her crown in 2021. She holds the record for most wins, podiums, pole positions, and points in this tournament.

Chadwick also currently serves a role as the development driver for Williams in F1.

Jutta Kleinschmidt

In 1997, Jutta Kleinschmidt famously became the first woman to win a race at any stage of the Dakar Rally. Also in 2001, she remains the only woman to win the Dakar Rally and the only German to top the car category.

Lella Lombardi

Lombardi remains the only female to register points in F1. She famously finished sixth in the Spanish GP, a tournament that unfortunately led to the death of five spectators. 

Lombardi would go on to compete in 12 F1 races before her demise in 1992.

Maria Teresa de Filippis

She became the first woman to compete in Formula 1 and went on to compete in five Grand Prix from 1958 to 1959 after winning her first race on the Amalfi coast. 

Michèle Mouton

Who would you say is the most iconic female driver of all time? Michèle Mouton is in that conversation.

She came out victorious in four races for the Audi factory team before famously finishing a close second at the drivers’ world championship race in 1982, behind German driver Walter Rohrl who is widely regarded as one of the greatest rally drivers of all time. To add to this, the French driver won the Pikes Peak International Hill Climb four years later in a record-breaking race.

Molly Taylor

Taylor won three of the five races held during the Extreme E Championship tournament last year, enough to earn her the top spot. The Aussie had previously won the Australian Rally Champion in 2016, becoming the first female and the youngest driver of any gender to achieve this feat.

Sarah Fisher

Sarah Fisher made nine starts in the Indianapolis 500 between 1999 to 2010 and remains the only woman to have as many stars in this tournament. She registered a career-best 17th finish at the 93rd Indianapolis 500 held in 2009, beating the previous career-high (18th) she recorded two years prior.

Fisher has made 81 appearances in the IndyCar Series and was the recipient of the ‘Most Popular Driver’ award on three occasions. She also raced in the NASCAR West Series from 2004 to 2005. 

Susie Wolff

After driving for the Deutsche Tourenwagen Masters (DTM) team for seven years, Wolff was signed to the Williams F1 team as a testing and development driver in 2012. Two years later, she raced at the British Grand Prix in 2014, becoming the first woman to participate in an F1 race in 22 years.

Automation is excitingly taking over our world. Many industries have seen massive integration of automated technologies, from automobile and aviation all the way down to sports. 

VAR referees in sports such as football are abundantly adopting automation. Consequently, punters betting on top odds on betting sites like  https://www.telecomasia.net/sports-betting/tips/basketball/ are even more thrilled because such automation reduces the frequency of human refereeing errors, ultimately increasing their chances of winning.

Of course, it is not just sports. The automobile industry is at the frontiers of automation – seen explicitly in the development of autonomous cars.

Self-driving cars are expected to be on the roads within the next five years. And not just on any roads, self-driving cars are expected to also be on busy urban roads.

This is a stimulating reality. Why? Because autonomous cars will have to deal with pedestrians, bicyclists, motorcyclists, and other traffic participants.

Yes, we have gradually seen autonomous cars appear on our streets, and they’re completely driverless. Exciting as this appears, autonomous cars on urban roads have such consequences.

Specifically, what do these cars mean for pedestrians? Will they be safer on the streets? Will pedestrians be safer at crossings? Let’s see how self-driving cars can mix with pedestrians.

A few years ago, automobile companies like NuTonomy, GM, and Uber announced that they would begin testing driverless cars in Pittsburgh and Singapore. 

These regions have an extremely active pedestrian community. They ensured that these cars would not be allowed to exceed 25 mph, that they would be closely monitored, and that they would be equipped with emergency brakes.

Results were largely positive, with the world warming up to a future of steering wheels having no humans actively behind them.

But are we getting too lazy to drive a car? Why the hype for self-driving cars?

Why are autonomous cars preferable?

Pedestrian injuries statistics show that various factors contribute to their occurrence. Some of which include:

• Impatient Drivers
• Recklessness
• Impaired Drivers
• Distracted Drivers
• Over speeding
• Drunk driving
• Weather conditions

The common human errors that are noted above are being eliminated with autonomous cars, resulting in a 95% safer car for pedestrians and passengers.

The Benefits of Autonomous Cars

Knowing how self-driving cars can mix with pedestrians is a bit of a “chicken and egg question”. The first question is: are these cars safer? The second is: are pedestrians safer? 

Autonomous cars are safer for pedestrians because they will react to their surroundings more quickly and better assess potential dangers. Apart from this, other benefits of autonomous cars are:

They have a higher level of safety: Unlike human-driven cars, autonomous vehicles can be trained to be safety-conscious. 

With sensors and cameras, drivers and pedestrians are safer since human error is eliminated.

Traffic efficiency: Autonomous cars can communicate with one another, which is a major benefit. With this ability to communicate in real-time, cars could travel efficiently at optimal distances from one another. Additionally, they would recommend the best route so you wouldn’t suffer from bumper-to-bumper traffic.

Eco-friendly: Another significant advantage of self-driven cars is that they are environmentally friendly. Rather than using internal combustion engines, autonomous cars are likely to be electric. 

Furthermore, the constant speeds that self-driving cars will travel at will reduce the need for perpetual braking and accelerating. This will reduce emissions and help make self-driving cars more environmentally friendly for passengers and pedestrians.

The Effects of Autonomous Vehicles on Pedestrians

Inevitably, there are some concerns about driverless cars. What are sticking points hindering their holistic adoption?

Security issues: Hacking is one of the potential cons of self-driving cars. Automated cars would need to share the same network protocol to communicate and coordinate. 

However, if many cars shared the same network, they would be vulnerable to hackers. A single hack on a busy road could cause significant damage by causing accidents and gridlock.

Moral Machine dilemma: Autonomous cars cannot make judgments between multiple unfavorable outcomes, which is another disadvantage. 

Increased Exposure To Radiation: Autonomous cars can expose pedestrians and passengers to electromagnetic fields. This could come from the heightened levels of navigation, GPS tracking tools, remote controls, powered accessories, radios, music systems, Bluetooth, Wi-Fi connectivity…that come with an autonomous vehicle.

Can Autonomous Cars and Pedestrians Coexist Safely?

Traffic laws and sensing solutions must be adapted for autonomous vehicles to coexist successfully with pedestrians in cities. However, at this point, the sensors used by most automakers are unable to deliver accurate detection and, therefore, cannot reach full autonomy. 

Due to the current packet of sensors being insufficient to handle fully autonomous vehicles, we have yet to see them take over our streets. 

Currently, most automakers’ sensing technologies like radars, cameras, and LiDAR cannot provide complete coverage and detection in all situations. Therefore, a human driver must be ready to take over at any moment.

An excellent possibility for the safe coexistence between autonomous cars and pedestrians is upgrading radar, cameras, and LiDAR sensors used in these vehicles to thermal sensors.

In contrast to other sensing solutions, thermal sensors can deliver accurate detection and classification. Unlike radar, LiDAR sensors, and FIR cameras, they pick up heat from objects, making them passive technologies.

To prepare society for the implementation of self-driven cars, separate lanes can be created for these cars, and the implementation of traffic laws guiding pedestrians against autonomous cars needs to be enforced.

In addition, special gadgets like pedestrian collision avoidance systems should be installed. With this system, autonomous vehicles can easily stop when they come close to pedestrians through the use of sensors (thermal).

From our deduction above, we can conclude that self-driving cars can only coexist with pedestrians if the right technology, laws, and environment are in place. 

We can’t say the future is too far off. The likes of Motional, Uber, AutoX, Optimus Ride, and Tesla are working tirelessly to roll out their fully autonomous cars soon.
