    摘要: A vehicle brake and wheel anti-lock control system in which an electronically controlled actuator normally provides brake pressure for the vehicle wheel brakes and also acts as a modulator to vary the brake actuating pressures for wheel anti-lock control. The actuator is so arranged that a master cylinder may be used to provide actuating pressure to the wheel brakes, the pressure passing through the actuator pressurizing chamber, if for any reason the actuator does not perform as needed to provide brake actuating pressure to stop the vehicle.

    摘要: A method to assist steering of a vehicle equipped with an active steering system when operating in a reverse direction is provided. The method comprises monitoring vehicle operating characteristics and an operator steering input. Boundaries of a target region and a reference point are determined. A target steering angle range is calculated based upon the reference point and the target location. A controlled steering angle of the active steering system is corrected when the operator steering input is outside the target steering angle range. An aspect of the invention included determining the reference point comprising a point of intersection of a first vector and a second vector, the first vector parallel to and passing through a centerline of a rear axle of the vehicle and the second vector perpendicular to and passing through a centerline of an inside front steerable wheel of the vehicle.

    摘要: Method and apparatus for improving the fuel economy of a vehicle of the type having a vehicle electrical system that includes a generator senses a vehicle voltage of the vehicle electrical system during determined intervals, and supplies an offset current from an external source of electrical energy to the vehicle electrical system in response to the sensing of a vehicle voltage of the vehicle electrical system. In this manner, the electrical power output of the generator, and its effect on fuel consumption, are reduced in response to supplying of the offset current. A source of electrical energy external to the electrical system of the motor vehicle is controlled by an electronic control unit coupled to the source of electrical energy. A power converter receives on and off commands from the electronic control unit in response to vehicle voltage measurements by the electronic control unit.

    摘要: A lane monitoring system deployed on a vehicle is provided for monitoring the position of the vehicle relative to a lane in which the vehicle is traveling. The system comprises a front camera for capturing front lane image data relating to an area substantially to the front of the vehicle and a rear camera for capturing rear lane image data relating to an area substantially to the rear of the vehicle. A processor is coupled to the front camera and the rear camera and is configured to receive the front lane image data and the rear lane image data. The processor is further configured to determine the position of the vehicle relative to the lane boundary from (1) the front lane image data when the front camera is operational, and (2) the rear lane image data when the front camera is not operational and the rear camera is operational.

    摘要: Electrohydraulic braking applied to a plurality of automotive vehicle braking channels operates to drive brake pressure modulator position toward a position corresponding to a braking input and corrected for channel to channel braking variations and vehicle deceleration error. A function for adapting the braking input to a position command is provided for each channel and is periodically adapted in accord with a difference between the channel's brake pressure modulator position error and a desired position error.

    摘要: A torque transducer senses the operator exerted steering torque and provides an output signal which varies in magnitude from a low value representative of a large operator exerted steering torque in one direction through a mean value representative of no operator exerted steering torque to an upper limit value representative of a large operator exerted steering torque in the opposite direction. The controller develops a zero torque reference which has an initial value substantially corresponding to the mean value of the torque transducer output signal, and steering torque assist is developed in relation to the difference between the zero torque reference and the transducer output signal. In operation, the zero torque reference is shifted according to a predetermined time response characteristic in a direction to reduce the difference between it and the transducer output signal. Over a period of time, the shifting of the zero torque difference due to operator exerted steering torque tends to cancel out and the remaining shifting adaptively compensates the zero torque reference for drift and other like sources of error affecting the magnitude of the transducer output signal.
