Traction control system pdf

Traction control is a widely used control system to increase stability and safety of four wheel vehicles. The anti-lock brake system ABS is regarded as the origin of all traction control systems and the electronic stabilisation programme ESP as the higher-level system in this case. Since the system resets with every ignition switch cycle, this procedure needs to be performed at the beginning of every ride until the safety recall service has been completed.

NOTE: While the Traction Control function will be disable this does not affect other functions of the Reflex Defensive Rider System (RDRS). Torque control accuracy. The vehicle traction control system computes the necessary torque required to be transmitted by the clutch and sends a torque command to the clutch controller.

The ideal clutch and control system should react to the torque command within an acceptable response time and accuracy. How does traction control work in your vehicle? How to turn traction control off? Why your traction control warning light is on, and what to do? The feature kicks in when your car struggles to speed up on slippery or low-friction road surfaces.

The system has wheel speed sensors for monitoring the rotation speed of all or. Enter electronic traction control. In modern vehicles, traction - control systems utilize the same wheel-speed sensors employed by the antilock braking system.

These sensors measure differences in rotational speed to determine if the wheels that are receiving power have lost traction.

This is an indication that a serious problem exists and should be addressed as soon as possible. See the bottom of this article for a list of generic diagnostic trouble codes that are designated for the traction control module. See full list on yourmechanic. A traction control system (TCS) switch is installed in some cars and gives drivers the ability to turn traction control on and off.

This may become necessary in situations where wheel spin and acceleration is required to get unstuck. If the traction control module is going bad or failing, traction control may remain on even when the switch has been turned off. It is also possible that turning the traction control off will not be possible. It is important to note that although this could be a symptom of a failing traction control module, it could also be an indication that the traction control switch is not workingproperly and needs to be replaced.

The traction control system (TCS) and the anti-lock brake system (ABS) work together to maintain control when hydroplaning. Most of the time a car does not hydroplane for long enough to require the traction control system (TCS) to kick in. However, when the traction control system (TCS) is not working properly, it will not be effective in helping to maintain control of the car during the occurrence of any hydroplaning incident. The ability to brake safely may be diminishe it may be necessary to apply more pressure to the brake pedal when stopping, and the likelihood of hydroplaning and loss of traction are greater. A helpful comparison can be made with anti-lock braking systems (ABS).

In fact, ABS setups are the foundation upon which traction control systems are built. The Braking System , Traction Control System If the ABS indicator and the brake system indicator come on together, and the parking brake is fully release the front-to-rear braking distribution system may also shut down. Test your brakes as instructed on 10.

If the brakes feel normal, drive slowly and have your vehicle repaired by your. TRACTION SYSTEMS FOR LOCOMOTIES AND HIH-SPEED APPLICATIONS. ABB is the expert for traction converters, motors, transformers, and complete traction chain solutions.

ABS systems are designated by the format XS-YM where X is the number of sensors in the system and Y is the number of modulators. There are always an even number of sensors, but depending on the installation, individual modulators may control more than one wheel. Example: A 6S-4M system has sensors and modulator valves.

If a fault occurs in any of the components that affect the operation of either system , one or both warning lights will come on and a diagnostic trouble code (DTC) will be set in the control module that corresponds to the fault(s). At the time it was under warranty. It would come on and go off with no other symptoms.

A defect, corroded contacts or water damage in this computer can result in the entire system going offline, which will turn on the TCS warning light.
