A power drive system is adapted for a sliding door mounted on at least one side of a vehicle for sliding movement forwardly and rearwardly of the vehicle. The system includes a reversible motor. A bracket is guided within a guide along a fixed path between the opened and closed positions of the door. An elongated drive member is slidably disposed within the guide and connected to the bracket at one end for driving the bracket along the fixed path. A translator mechanism operably engages with the drive member for powering movement of the door. The translator mechanism can include a rotatable hub, operably engageable with the drive member, a gear transmission for driving the hub, and a clutch mechanism for connecting the motor to the transmission. The translator mechanism preferably has sufficient power to pull the sliding door into a primary latch position with respect to the corresponding portions of a latch mechanism attached to the door and frame defining the door opening. A power striker moves the door into and out of sealing engagement with the frame. A lock mechanism selectively maintains the latch in a locked position. At least one sensor provides an input signal to a control system corresponding to movement of the door, position of the lock mechanism, and position of the power striker for controlling the door drive unit, power striker drive unit, and lock mechanism drive unit in accordance with a program stored in memory.

A closure system for a motor vehicle includes a closure, a closure frame, an electric motor, a control switch, an electric power source, first and second displacement sensors, temperature sensor, voltage sensor of the power source and a microprocessor. The first and second displacement sensors each operably generate a signal indicative of the one of closure movement and output shaft rotation. The microprocessor is electrically connected to the control switch, the electric motor, the first and second displacement sensors, the temperature sensor and the voltage sensor of the power source. The microprocessor includes electrically connecting the motor with the power source responsive to a condition of the control switch. The microprocessor also has means for converting temperature sensed to an electrical signal indicative of the temperature. The microprocessor also includes converting voltage sensed to an electrical signal of power source voltage, and calculating a velocity of one of the closure and the motor between predetermined positions as indicated by transition signals from the displacement sensors as the closure is moved from an open position to the seated position. The microprocessor further includes calculating a compensated velocity by using the calculated velocity and the voltage signal and the temperature signal. The microprocessor yet further includes comparing the velocity with a reference velocity and electing to reverse the motor when the compensated velocity is less than the reference value.

A closure system for a motor vehicle includes a closure, a closure frame, an electric motor, a control switch, an electrical power source, first and second displacement sensors, a temperature sensor, a current sensor for a current being drawn by the electric motor, and a microprocessor. The first and second displacement sensors each operably generate a signal indicative of closure movement. The microprocessor is electrically connected to the control switch, the electric motor, the first and second displacement sensors, the temperature sensor and the current sensor. The microprocessor electrically connects the motor with the power source responsive to a condition of the control switch. The microprocessor also converts the temperature sensed to an electrical signal indicative of the temperature, and converts the current sensed to an electrical signal indicative of motor current. The microprocessor uses the signals for current and temperature to calculate a temperature compensated drag force of the closure at a number of predetermined closure positions. The microprocessor determines the closure position by using signals from the displacement sensors. The microprocessor compares the temperature compensated drag force with a reference drag force and reverses the motor when the compensated drag force is greater than the reference drag force.
