Trigger conditions

An emergency braking situation is identified by the following trigger conditions, triggering intervention by the brake assist system. These conditions must be fulfilled:

• The signal from the brake angle sensor indicating that the brakes have been applied.
• The signals from the speed sensors indicating how fast the vehicle is traveling.
• The signal from the brake pressure sender indicating how fast and with what force the driver has applied the brakes. This means that the control unit determines the change in current brake pressure via the pressure sensor in the hydraulic unit over a certain period of time.

Therefore, no intervention occurs if:

• the brake pedal is pressed too slowly or not at all,
• the change in pressure remains below the threshold,
• the vehicle speed is too low, or
• the driver has applied the brakes with sufficient force.
