Longitudinal acceleration estimating method for motor vehicle, involves delivering comparison information signal, and delivering acceleration information signal by comparing projection information signal with comparison information signal

摘要

The method involves calculating an acceleration information signal (S5) of a motor vehicle from a speed information signal (S2) of the vehicle. A total acceleration signals (S3) corresponding to a longitudinal projection information signal (S1) of total acceleration is filtered and synchronized to deliver a total synchronized acceleration information signal (S4). The signals (S4, S5) are compared, and a comparison information signal (S6) is delivered. A longitudinal acceleration information signal (S7) of the vehicle is delivered by comparing the signals (S1, S6). An independent claim is also included for a device for estimating longitudinal acceleration of a motor vehicle.
