What is ASR? What is the Anti Skid System? What does ASR do? Which vehicles is ASR located?
ASR stands for anti-skid. This system prevents the vehicle from skidding when the driver presses the gas pedal, especially on slippery terrain. Although they are different from ASR and TCS in automotive, their functions are similar: To stop the vehicle skidding. ASR, abbreviation of “Anti Schlupf Regelung”, is known as Anti Skid System in Turkish. TCS stands for “Traction Control System”.
First, it is important to note that a vehicle that skids starts slower than a vehicle that does not skid.
Imagine you need to cross in heavy traffic quickly. If you panic and overload the accelerator, the vehicle will skid and tires spin for a while. ASR is commonly used in powerful, rear-wheel-drive vehicles.
What is ASR?
Imagine that you overdo the accelerator pedal, and your vehicle begins to skid. ASR detects skids thanks to speed sensors.
1) By activating ABS hydraulics it applies brakes to spinning wheels.
2- It reduces power by interfering the fuel injector or ignition device. This process continues until the skidding stops.
These operations are performed by TCS-ASR using the following parts.
Sensors for wheel speed:
These parts detect the wheel’s rotational speed. These parts detect the speed of the wheels using traction and determine which wheel is spinning.
ABS hydraulics:
Each wheel can be controlled individually by the valves within this part. ABS hydraulics are used by ASR to reduce the speed and apply the brakes to the appropriate wheel.
Electronic control unit (ECU).
This article explains what the ASR should do when in critical situations. The following parts can be used to control the engine’s power and reduce wheel speeds by ASR:
- Fuel throttle valve
- Ignition assembly
- fuel injector
- gas pedal sensor
This shows that ASRs and ABS work together. The cooperation between these systems has resulted in the development of the ESP system for vehicles.
ASR systems work best on snowy roads, icy roads and muddy roads. The ASR system can be disabled by the driver with a button located inside the vehicle.
What vehicles can the ASR System apply to?
It can be used on any vehicle equipped with ABS brake system or injector system.
What are the benefits of the Traction Control Systems?
If the accelerator pedal is pressed too hard on slippery surfaces (wet or icy), vehicles without Traction Control System will fail to accelerate. The traction wheels may become inactive while the vehicle is turning and cause it to skid.
Safe handling in all conditions is possible for vehicles equipped with Traction Control Systems.
- Driving safety is improved
- Prevents vehicle from skidding around bends
- It allows for safe driving on slippery surfaces
- Easy take-off in any road condition (muddy, wet or icy).
- Tires last longer
- Axle, clutch pad, gearbox etc. Drivetrain life extension
- Can be deactivated at any time
- It can be used at ambient temperatures between -40 C and +80 C.
