摘要： A windshield wiper system (10) having variable frequency induction motor control for reducing wipe speed at reversal points includes an induction motor (12), a wiper and blade assembly (14) operatively connected to the motor (12), a sensing means (22) for detecting when the position of the wiper and blade assembly (14) is within a preselected range of one of the reversal points, and a motor control (18) responsive to the control signal (S2) generated by the sensing means for causing the motor (12) to reduce wipe speed during the preselected range prior to the reversal point to reduce pattern growth, noise, and water expulsion. The sensing means (22) takes the form of a cam or plate operated switch driven by the induction motor. The control signal (S2) derived from the cam operated switch is provided as an input to a voltage controlled oscillator (18), whose variable frequency output is used to vary the frequency of the excitation voltage applied to the windings of the three phase induction motor (12).

摘要： A windshield wiper control system (10) improves vehicle windshield wiper operation selectively controlling the motor speed of a dc motor (14) that drives the wiper blade (16) across the windshield. The motor speed is reduced for a portion of the wiper pattern adjacent the reversal points at each end of the wiper pattern. The motor speed is changed as a function of blade position by varying the duty cycle of an excitation voltage signal provided to a variable speed dc motor (14). The disclosed embodiment is useful for variable and continuous speed control in a vehicle wiper system.

摘要： 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, means for sensing a temperature, means for sensing a voltage of the power source and a microprocessor. The electric motor has an output shaft. The closure frame defines a seated position of the closure. An electrical power source includes a battery. 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 means for sensing a temperature and the means for sensing a voltage of the power source. The microprocessor includes means for 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 means for converting voltage sensed to an electrical signal of power source voltage, and means for 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 means for calculating a compensated velocity by using the calculated velocity and the voltage signal and the temperature signal. The microprocessor yet further includes means for comparing the velocity with a reference velocity and electing to reverse the motor when the compensated velocity is less than the reference value.

摘要： 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, means for sensing a temperature, means for sensing a current being drawn by the electric motor and a microprocessor. The electric motor has an output shaft. The closure frame defines a seated position of the closure. The electrical power source includes a battery. 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 means for sensing a temperature and the means for sensing a current. The microprocessor includes means for 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 means for converting current sensed to an electrical signal of motor current, and means for calculating a drag force of the closure at predetermined positions as indicated by signals from the displacement sensors as the closure is moved from an open position to the seated position. The microprocessor further includes means for calculating a compensated drag force using the drag force and a temperature correction factor. The microprocessor yet further includes means for comparing the drag force with a reference drag force and electing to reverse the motor when the compensated drag force is less than the reference drag force.
