System Description: Notes

Adaptive brake assists the driver in dangerous situations which occur suddenly, and thus enhances active safety. To do so, the electronic stability program control unit evaluates the data from the following components in order to detect the current driving situation:
- Left front axle rpm sensor
- Right front axle rpm sensor
- Left rear axle rpm sensor
- Right rear axle rpm sensor
- Steering angle sensor
- Brake lights switch
- Brake vacuum sensor
The electronic stability program control unit is located in the front left of the engine room.
The electronic stability program control unit contains the control for the following systems:
- Vehicle dynamics control (VDC)
- Standstill control (SSC)
- Electronic brake force distribution (EBD)
- Emission test, roller dynamometer mode
- Anti-lock braking system (ABS)
- Acceleration skid control (ASR), traction control system (TCS)
- Brake assist system (BAS) (without ICC)
- Brake assist system PLUS (BAS PLUS) (with ICC)
- Hill start assist
- Dry braking
- Precharging, depending on accelerator pedal actuation
- Precharging, depending on lateral acceleration
- Extended traction control
- HOLD function (with ICC)
- Steering assistance
- System malfunction display function
The electronic stability program control unit has the following tasks:
- Reading in of signals
- Evaluation of input factors
- Actuation of components
Reading in of signals
- Direct line
- CAN communication
Evaluation of input factors
- The input factors that have been read in are evaluated by the integrated microprocessor and the affected components are then actuated.
