Abstract

A method for terminating a braking intervention of an adaptive cruise control system of a motor vehicle. The braking intervention is terminated in accordance with a predefined algorithm in response to the driver overriding of the adaptive cruise control system. In this context, the algorithm is formed in such a manner that a jerk-free transition from braking to acceleration of the motor vehicle is ensured, thus increasing the ride comfort. The transition from braking to acceleration preferably takes place in accordance with a linear function. Provision can also be made for stepwise functions. To prevent the braking operation from being terminated prematurely by an inadvertent actuation of the accelerator, provision is made for a threshold value to be adjusted for the accelerator for a desire of the driver to accelerate. This threshold value is dependent on the deceleration during braking. The higher the braking deceleration is, the more heavily the driver must operate the accelerator to initiate the acceleration process. In the case of a low deceleration, the threshold value is lower, so that it suffices to step more lightly on the accelerator to bring about an acceleration of the …
