Method and device for automatic controlling of the deceleration of a vehicle
First Claim
1. A method for automatically controlling deceleration devices of a vehicle during automated braking, comprising:
- detecting a surrounding-field situation and a particular situation by detection devices before and during automated braking of the vehicle involving all wheels of the vehicle;
determining a first risk dimension for continued deceleration of the vehicle and a second risk dimension for unbraked further movement of the vehicle in accordance with the detected situations; and
deciding whether the deceleration devices remain activated or are deactivated in accordance with a comparison of the first risk dimension and the second risk dimension.

Abstract
A method and a device for controlling deceleration devices of a vehicle during a braking operation, e.g., a vehicle which is equipped with a sensor for adaptive cruise control. During the braking operation, risk dimensions are determined on the basis of driving dynamics models, which are individualized by signals of the surrounding-field sensor system. A first risk dimension is precalculated for the case of continued deceleration and a second risk dimension is precalculated for the case of unbraked further movement of the vehicle. Through the comparison of the two risk dimensions, it is decided whether the automatic vehicle deceleration is to be maintained or whether the braking is to be canceled before the vehicle is brought to a standstill.
