Actuator i.e. clutch, managing method for four-wheel drive motor vehicle, involves measuring torque transmitted by actuator, and determining current to be transmitted to actuator from difference between measured torque and torque setpoint

摘要

The method involves calculating a feedback torque setpoint to be transmitted to an actuator (5). The torque transmitted by the actuator is measured by a torque sensor (13). Current to be transmitted to the actuator is determined by a proportional integral derivative (PID) type closed loop control from difference between the measured torque and the feedback torque setpoint obtained by a subtractor. Independent claims are also included for the following: (1) a computer medium comprising a computer program for implementing an actuator managing method (2) a four-wheel drive motor vehicle comprising an engine.
