Abstract
The vehicle weight determination device includes a microcomputer for achieving the vehicle weight determination by obtaining a driving force after filtering based on the speed ratio of the torque converter and obtaining an integrated driving force with the absolute value of the driving force after filtering by using an area method. Similarly, acceleration after filtering is obtained by filtering process of the acceleration and an integrated to obtain an integrated acceleration. The vehicle weight is determined by the integrated driving force divided by the integrated acceleration.
