1. Avoiding obstacles with a higher degree of safety, including during emergency braking.
2. Reducing the braking distance during emergency braking while maintaining the stability and controllability of the car, including when turning.
In the event of a system failure, a diagnostic function and a fail-safe system are provided.
Traction control system (TCS) - a variable system designed to adjust traction during acceleration or cornering. The system controls the vehicle's movement by applying brakes to one of the vehicle's wheels or by suppressing excess engine power to prevent the vehicle from skidding and maintaining directional stability.
Traction control is automatically enabled after the engine is started, but can be disabled with the TCS button.
Hydroelectronic control unit (GEBU) receives information about vehicle speed, direction of travel and road conditions from wheel speed sensors.
Based on this information, the control unit determines the optimal wheel braking mode.
Electronic brake force distribution (ERTS) is a subsystem of the ABS and serves to ensure effective traction of the rear wheels with the ground.
In addition, based on the high efficiency of the perfect ABS ERTS, it prevents the rear wheels from skidding during partial braking modes.
The braking force is maintained close to the optimum value and is controlled electronically, which eliminates the need for a conventional pressure regulator. Since the pressure regulator is a mechanical device, it has limitations in terms of achieving ideal distribution of braking force to the rear wheels, as well as flexible distribution of forces depending on the degree of vehicle load. In addition, if the mechanical pressure regulator is faulty, then this is not detected by the driver. The ERTS, controlled by the ABS ECU, calculates the amount of slip on each wheel at a time and adjusts the amount of pressure in the rear wheel brakes so that it exceeds the pressure in the front wheel brakes. In the event of a malfunction of the ERTS, the ERTS warning lamp lights up in the instrument cluster (EBD) (and parking brake).
Advantages of ERTS:
- Improving the performance of the basic braking system.
- Compensation for differences in friction coefficients.
- Elimination of the pressure regulator.
- Malfunction signaling by a control lamp.
