Mass calculating method for motor vehicle i.e. commercial vehicle, involves utilizing measurement of height in combination with values of stiffness of suspension to calculate total mass of vehicle and to deliver information to driver

摘要

The method involves measuring height of wheels (4) with respect to a body by a height sensor (2) to carry out height correction in a short time after variation of mass of a vehicle. Measurement of the height is used in combination with values of stiffness of a suspension during the short time before starting of height correction so as to calculate total mass of the vehicle and to deliver total mass information to a driver. Signals are received based on a state of the vehicle by an on-board network i.e. controller area network (CAN)(8). An independent claim is also included for a motor vehicle comprising suspensions.
