Abstract
A device for preventing a rollback of a vehicle on an incline. The vehicle is equipped with a brake system, via which at least the braking pressure in the wheel brakes of a rear wheel is influenced in order to distribute the braking action between at least one front wheel and one rear wheel by actuating actuators assigned to the rear wheels so that a differential is set between the pressure of the front wheel and the rear wheel (e.g., an EBD braking). The device has a first arrangement for determining whether vehicle standstill is occurring due to braking where a differential in the braking pressure of the front wheel and the rear wheel has been set. The device also includes a second arrangement for determining whether the vehicle is rolling back from a standstill. If the second arrangement detects a vehicle rollback, the braking pressure in at least one rear wheel is increased to inhibit rollback.
