Acceleration monitoring method for a longitudinal dynamics open-loop or closed-loop controller in motor vehicles
First Claim
1. Acceleration monitoring method for a longitudinal dynamics open-loop or closed-loop controller of a motor vehicle, comprising the steps ofcomparing an actual acceleration value with a desired acceleration value, detecting a defective operating condition of the motor vehicle when the actual acceleration value is outside an error corridor including the desired acceleration value, wherein a width of the corridor extends over a range of values of acceleration from a first value of acceleration equal to the desired acceleration plus an incremental value of acceleration to a second value of acceleration equal to the desired acceleration minus a further incremental value of acceleration and setting the error corridor in a variable fashion as a function of current handling performance of the motor vehicle.

Abstract
An acceleration monitoring method for a longitudinal dynamics open-loop or closed-loop controller in motor vehicles, in which an actual acceleration value is compared with a desired acceleration value, a defective operating condition of the motor vehicle being detected when the actual acceleration value is situated outside an error corridor including the desired acceleration value. In a method in which Critical driving situations can be detected as quickly as possible, wherein the error corridor is set in a variable fashion as a function of the current handling performance of the motor vehicle.
