  • Patent number: 11828363
    Abstract: A method for controlling an engagement and disengagement of a vehicle transmission parking lock. A vehicle present speed is ascertained when a device for activating the parking lock is actuated. When the vehicle has not yet reached a standstill and the present speed exceeds a threshold value, engagement of the parking lock is prevented. When the vehicle has not yet reached a standstill and the present speed falls below the threshold value, the vehicle activates the parking brake and is braked until the standstill is reached or until the present speed has reached substantially zero. A present gradient value of the roadway and/or a vehicle longitudinal inclination value is also ascertained. Based on these values, it is checked whether a hydraulic brake system of the vehicle is activated or whether the already activated parking brake should be deactivated.
