Title:
自動車の質量を測定するための方法
Document Type and Number:
Japanese Patent JP4939604
Kind Code:
B2
Abstract:
A method for determining a motor vehicle mass which is implemented in conjunction with shifting an automated shift transmission from a current gear to a desired gear. In determining the mass, a value force and movement parameters are determined partly before or after the shift operation and partly during it. For the more rapid and accurate determination of mass, the drive-wheel-related traction force of the drive engine before and after the shift F_zug_vor, F_zug_nach, the longitudinal acceleration of the vehicle before and after the shift, a_zug_vor, a_zug_nach, and the acceleration a_roll determined in the traction-force-free phase during the shift are determined, and from these and in accordance with the equation m=F_zug/(a_zug−a_roll), a first mass value m_vor=F_zug_vor/(a_zug_vor−a_roll) is calculated for the beginning of the shift and a second mass value m_nach=F_zug_nach/(a_zug_nach−a_roll) is calculated for the end of the shift.
