A system is provided for determining the current weight of a vehicle and any implement or trailer being towed or carried thereby. The system has an electronic control unit and means to determine the current value of vehicle operating parameters indicative of the current wheel output torque and acceleration of the vehicle. These current parameter values are forwarded to the electronic control unit so that the unit can calculate the current vehicle weight from a predetermined relationship involving wheel output torque, vehicle acceleration and other known current operating parameters of the vehicle. The other known current operating parameters of the vehicle are wheel rolling radius, angle of inclination of the vehicle, gravitational acceleration and rolling resistance of the wheels. When the vehicle includes a hydrostatic mechanical CVT which has a hydraulic drive circuit in which a hydraulic pump supplies pressurized fluid to a hydraulic motor, the level of pressure in the drive circuit provides an indication of the current wheel output torque.
