Abstract
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.
