Electronic Brake Force Distribution (Ebv)

Electronic Brake Force Distribution (EBV)
Electronic brake force distribution prevents over braking of the rear axle when the system is intact (rear axle influencing function, HA) and in the event of an ABS failure (EBV emergency operation). The HA function prevents the rear wheels from going into ABS control mode before the front wheels when the vehicle is braked both in straight ahead driving and with sufficiently high deceleration and also when cornering. This ensures a high level of vehicle stability.
The EBV emergency operation function prevents over braking in the event of ABS failure under the following combinations:
^ Effective until the failure of 2 wheel speed sensors. The failure can occur in any order.
^ Effective with intact pump motor activation (pressure holding function or pressure decrease meeting requirements at the rear axle).
^ Effective even if the admission pressure sensor fails.
In the event of system malfunctions or additional sensor faults, the driver is alerted by the red brake warning lamp in the instrument cluster.
