Degraded Dynamic Brake Function (DDBF)
WARNING: This page is about a different car, the 2018 Land Rover Discovery Sport, 2017 Land Rover Discovery Sport, 2016 Land Rover Discovery Sport, and 2015 Land Rover Discovery Sport. However, it is still accessible from the selected car via links, so may be relevant.
The braking operation is controlled by the ABS control module. The ABS control module monitors the deceleration rate using the wheel speed sensor signals if available, and adjusts the hydraulic pressure to the brakes as necessary to achieve the required deceleration. If all wheel speed sensors have failed, the longitudinal acceleration sensor is used to monitor vehicle deceleration.
