How Does Tesla Model S Traction Control Work?

The traction control system constantly monitors the speed of the front and rear wheels. If Model S experiences a loss of traction, the system minimizes wheel spin by controlling brake pressure and motor power. By default, the traction control system is always active. Under normal conditions, it should remain active to ensure maximum safety.

This indicator flashes on the instrument panel whenever the traction control system is actively controlling brake pressure and motor power to minimize wheel spin. If the indicator stays on, a fault is detected with the traction control system. Contact Tesla Service.

 

Warning:

  1. Traction control cannot prevent accidents caused by driving dangerously or turning too sharply at high speeds.
  2. If the above indicator remains illuminated in situations in which you have not enabled Slip Start (described next), the traction control system may not be operating correctly. Contact Tesla Service immediately.

Allowing Wheel Slip

To allow the wheels to spin at a limited speed, you can enable Slip Start. Slip Start can be enabled only when Model S is moving 48 km/h or slower. Slip Start automatically disables when the speed exceeds 80 km/h.

Under normal conditions, Slip Start should not be enabled. Enable it only in circumstances where you deliberately want the wheels to spin, such as:

  • Starting on a loose surface, such as gravel or snow.
  • Driving in deep snow, sand, or mud.
  • Rocking out of a hole or deep rut.

To allow the wheels to spin, touch Controls > Driving > Traction Control > Slip Start.

The instrument panel displays an alert message when Slip Start is enabled.

 

Although Slip Start is automatically disabled the next time you start Model S, it is strongly recommended that you disable it immediately after the circumstances that required you to enable it has passed.

What is the Function of the Traction Control Feature on a Car?

Technological developments today can be said to be extraordinary, as well as for cars. Various technologies to ensure safety while driving certainly bring its own advantages for every car passenger. One of the trending features is Traction control. Maybe Nissan Lovers have also heard the name of this feature. What exactly is this feature? How can this feature guarantee the safety of the driver?

Maintaining Stability When Turning and Helping Drivers When Turning are functions of traction control.

Maintaining Stability When Turning

What do you do when you are making a sharp turn and the car skidded and skidded? Of course, you will be very panicked. This is what actually wants to be minimized with a car feature called Traction control. Traction control is a useful feature to prevent tires from skidding and slipping during wet road conditions when turning corners. This feature is widely provided in the latest cars that ensure safety while driving.

This feature works automatically when the driver does not need to do anything, except press the activation button which is usually pinned near the steering wheel. With this feature, the car will detect the traction on each wheel and then apply the brakes on the wheel experiencing it.

Helping Drivers When Turning

When turning corners, the driver basically has to control three things at once: acceleration, braking, and steering. Of course, a little complicated to do, especially if the driver is not very proficient. Traction control will help the driver do this. The system will automatically brake on each wheel so as to keep the car turning safely. In addition, the power on the engine is also adjusted so that the wheels maintain grip.

Braking is not done haphazardly. Each wheel will be given its own brake force which may not be as strong, depending on the needs of the wheel itself. The sensor will assess how strong the brakes are needed on one wheel. That way, the car will not slip because the wheels suddenly stop.

Traction control is active for a moment when the car is about to turn. Automatically, the system will provide grip on each wheel to brake with a certain force. For example, the vehicle is cornering at a speed that is too high so it has the potential to cause the car to slip. Traction control will slowly apply the brakes until the car can turn gently and safely.

This system can also be active when going out of a corner. For example, when the driver presses the gas pedal too quickly when exiting a corner, the car will bounce out of the way. Traction control will brake gently and return the car to the right track.

5 Causes The Traction Control Indicator Light Is On

Today, modern vehicles are very concerned about safety systems. A traction control system or traction control system is one of those developed for modern cars. Traction or grip is very useful for the safety of the driver and passengers. When the vehicle loses traction on the road, the traction control system with its function, will detect this problem and act accordingly. The traction control indicator light will not come on as long as the system is functioning properly and there are no problems with its components. However, if there is a problem with the system, the indicator light will come on. In the following, we will tell you why the traction control indicator light is on.

If the traction control indicator light is on, it will usually light up when you accelerate. Don’t panic when this happens because you need to focus on stabilizing the steering wheel as best you can. The traction control system won’t help you like it used to, so you have to be extra careful in these conditions. The best thing you can do is slow down and find a mechanic to solve this problem.

Below are the top 5 causes of the traction control indicator light coming on when you’re accelerating.

Faulty Wheel Speed ​​Sensor

The wheel speed sensor is connected to your traction control system and engine control unit or ECU. These sensors are responsible for detecting the rotational speed of your wheels. Each wheel has its own sensor. If the rotational speed of each wheel changes unexpectedly or unusually as you accelerate, the wheel speed sensor will detect the change and notify the traction control system. But if the wheel speed sensor is not working, the traction control system will not be notified. Then your vehicle will lose traction and this is what causes the traction control light to come on.

Defective Steering Angle Sensor

The steering angle sensor calculates the angle of the steering wheel and the rate of rotation. Sensors are positioned in the steering column so they can track the angle and speed precisely. But if the sensor goes bad or even breaks, you may encounter the possibility that the traction control light is on. Therefore, it is important that you know the symptoms of a malfunctioning steering angle sensor.

Damaged Road Condition

If the road conditions are too severe, your traction control system may not be able to handle it. For example, if you live in a location with a lot of mud on the road, then the road will be difficult to maintain traction. If traction becomes too difficult, then your traction control light may be on the dashboard. This is indeed one of the unsolved problems of this system. There’s not much you can do. We recommend taking your vehicle to an area with better roads.

Steering Rack

The steering rack is attached to your steering wheel and is an important part of the power steering system. This system receives the high-pressure hydraulic fluid needed to make it easier to turn the steering wheel. Part of good traction is having smooth steering that is easy to control. So, if you have a bad or even damaged steering rack, it will be more difficult to steer your vehicle on rough roads. Damage to the steering rack will cause your traction control light to come on.

Programming Problem

In the traction control system, there is programming that goes with it. There are circumstances in which the traction control system must be reprogrammed due to problems with the programming. Sometimes these programming errors can occur over time. If the traction control system has this problem, the traction control light will flash continuously. Usually, this programming can only be completed in error. Therefore, if problems 1-4 are sure to be resolved, the final step is to bring the car into order to solve problem 5.
