Corrective torque determining method for motor vehicle, involves calculating value of oscillatory part of longitudinal speed based on longitudinal and rotational speeds, and calculating corrective torque based on value of oscillatory part

摘要

The method involves determining instantaneous longitudinal speed (Vvehi-inst) of a motor vehicle at given instant by a longitudinal displacement sensor (1), and determining instantaneous rotational speed (Nmot-inst) of a drive motor around the instant by a rotational displacement sensor (2). A value of an oscillatory part of the longitudinal speed is calculated based on the longitudinal and rotational speeds. Corrective torque applied by the drive motor is calculated based on the value of the oscillatory part of the longitudinal speed of the vehicle. Independent claims are also included for the following: (1) a method for controlling engine torque of a motor vehicle (2) computer program product comprising a set of instructions to implement a correction torque determining method (3) correction torque controlling device comprising a measuring unit.
