3234798 - E7022 VDC - Description
Description
The electronic anti-lock brake system (BOSCH 5.7 ABS with ASR) governs braking pressure sent to the wheels and prevents loss of grip under all tyre and road surface conditions.This is combined with a VDC (VEHICLE DYNAMIC CONTROL) system, which controls vehicle stability by modulating drive torque and braking the wheels differentially, if there is a loss of grip, thus helping to return the car to its correct trajectory.The VDC system acts on the engine and brakes to generate a stabilising torque when the ABS sensors detect conditions that could lead to the vehicle slipping.The VDC system includes the following specific components over and above those of the ABS:
- a sensor which detects the steering wheel position (steering sensor);
- a sensor which detects the vehicle's rotation around the vertical axis and side acceleration (centrifugal force) (yaw sensor);
- a sensor that detects pressure on the hydraulic ABS unit (pressure sensor)
the same warning light is also used for the ASR function; The VDC systems is connected to the ASR system . |
