Abstract: A power assisted automotive door system has a power drive module which includes an electric motor and integrated gearbox drive unit that provides a driving torque around the door's pivot axis. A controller is in communication with the electric motor, a torque sensor, a velocity sensor, and an accelerometer and processes measured and provided data and to predict a door torque using a real-time simulation. The controller commands the power drive module to produce a compensating torque that achieves a predetermined desired resistive door torque that corresponds to a desired door velocity in response to an operator's manual operation. The operator can move the door at any desired velocity only having to overcome the predetermined desired resistive door torque allowing the door to feel as if the vehicle is on flat and level ground.
