Corrective torque determining method for motor vehicle, involves determining value of oscillating part of acceleration of vehicle using rotational and longitudinal speeds, and determining torque based on value of part of acceleration

摘要

The method involves determining an instantaneous longitudinal speed (Vvehi-inst) of a motor vehicle at a given time using a longitudinal displacement sensor (1), and determining an instantaneous rotational speed (Nmot-inst) of an electric driving motor of the vehicle at the time. A value of an oscillating part (delta-XvT'') of a longitudinal acceleration of the vehicle is determined using the instantaneous rotational and longitudinal speeds. A corrective torque is determined based on the value of the oscillating part of longitudinal acceleration of the vehicle. Independent claims are also included for the following: (1) a method for controlling a motor torque of a motor vehicle (2) a computer program product comprising instructions to perform a method for determining a corrective torque (3) a motor torque controlling device comprising a longitudinal displacement sensor.
