A method for terminating an automatic braking process improves an automatic braking process by assuring that reliable termination of the braking process always takes place. Breaking-off criteria, which are independent of the actuation force of the brake pedal, are provided for the automatic braking process. The variables relating to the dynamics of vehicle movement or the activation time of the automatic braking process, if appropriate also as a function of variables relating to dynamics of vehicle movement, are used as the breaking-off criteria. Thus, automatic braking process is terminated as a function of vehicle behavior. In addition, the gradient of the braking pressure is determined as a function of the activation time and/or as a function of the switch-off criteria when the automatic braking process is terminated.
A method for terminating an automatic braking process for a motor vehicle, comprising the steps of initiating the automatic braking process upon fulfillment of a triggering criterion, building up a larger brake pressure with the automatic braking process than results from the position of a brake pedal, and terminating the automatic braking process by reduction of brake pressure to a brake pressure corresponding to a position of the brake pedal when a variable of a breaking-off criterion exceeds or drops below a threshold value assigned to the variable, wherein a variable relating to the dynamics of vehicle movement is the variable of the breaking-off criterion.
A method for terminating an automatic braking process for a motor vehicle, comprising the steps of initiating the automatic braking process upon fulfillment of a triggering criterion, building up a larger brake pressure with the automatic braking process than results from the position of a brake pedal, and terminating the automatic braking process by reduction of the brake pressure to a brake pressure corresponding to a position of a brake pedal when a variable of a breaking-off criterion varies in relation to an assigned threshold value, wherein an activation time which has passed since the start of the automatic braking process is the variable of the breaking-off criterion.
A method for terminating an automatic braking process for a motor vehicle, comprising the steps of initiating the automatic braking process upon fulfillment of a triggering criterion, building up a larger brake pressure with the automatic braking process than results from a position of a brake pedal, and terminating the automatic braking process by reduction of brake pressure to a brake pressure corresponding to a position of the brake pedal when a variable of a breaking-off criterion exceeds an assigned threshold value, wherein a gradient of the brake pressure reduction is determined as a function of the breaking-off criterion comprising at least one of activation time and an exceeding of the threshold value by an assigned variable relating to one of vehicle movement dynamics and brake pedal position.
