Traction Control System ( active safety system of a vehicle ) , works in conjunction with ABS and EBD. The system is designed to prevent slippage of the drive wheels , no matter how pressing the gas pedal and the road surface.
The operating principle of traction control system based on reducing the engine output with increasing speed of the drive wheels . On each wheel speed computer controlling the system learns from the sensors installed in each of the wheels and an acceleration sensor . Similarly, the same sensors are used in systems and ABS systems, torque control , however , often these systems are used simultaneously. Sensor signals , indicating that the drive wheels begin to slip, the computer decides to reduce engine power and have an effect similar to a decrease in the degree of pressing on the gas pedal , and the degree of discharge gas , the stronger the higher the rate of growth slipping .
This system is widely used in motor racing , Formula 1 first began to use it the Ferrari team in 1990.
Sometimes , in conjunction with this system is used with differential lock.
Depending on the manufacturer traction system has the following trade names :
cistema ASR (Automatic Slip Regulation, Acceleration Slip Regulation) on cars Mercedes, Volkswagen, Audi and others;
system ASC (Anti-Slip Control) on cars BMW;
System A-TRAC (Active Traction Control) on cars Toyota;
System DSA (Dynamic Safety) on cars Opel;
system DTC (Dynamic Traction Control) for cars BMW;
system ETC (Electronic Traction Control) on cars Range Rover;
System ETS (Electronic Traction System) on cars Mercedes;
system STC (System Traction Control) on cars Volvo;
system TCS (Traction Control System) on cars Honda;
System TRC (Traking Control) on cars Toyota.
