摘要： A current flowing to a motor 8 for generating a steering assist force for a steering mechanism is detected by a motor current detecting circuit 24 to be inputted to a controller 10 as a motor current detection value IMS. The controller 10 arithmetically determines deviation between the motor current detection value IMS and a desired motor current value IMT preset on the basis of a vehicle speed and a detected steering assist torque value and decides abnormality of the motor current detecting circuit 24 when the deviation indicates an abnormal value over a period equal to or longer than a predetermined time. When the abnormality is decided, the controller 10 stops motor control through a closed loop control in which the motor current detection value IMS is used as a feedback input, and then the controller 10 changes over the control to an open loop control in which a desired motor voltage is arithmetically determined on the basis of the desired motor current value IMT and resistance of the motor and applied thereto so that the current of the preset desired motor current value IMT can flow through the motor 8.

摘要： A unified control device for a vehicle including an anti-skid braking system and power steering control system is controlled by two microcomputers (4B and 24B). On the basis of the outputs of the torque sensors (1a and 1b, etc.), the first microcomputer (4B) determines the driving direction and torque of the DC motor (9) providing the assisting steering torque for the steering wheel, and outputs the torque signal (T) and the first direction signal (D1) for the DC motor (9). The second microcomputer (24B) generates the brake operation signal (B) on the basis of the outputs of the road wheel velocity sensors (21a through 21d) and the brake switch (22). Further, on the basis of the output of the torque sensors (1a and 1b), the microcomputer (24B) determines the direction of the DC motor (9), and outputs the second direction signal (D2). The motor drive circuit (8) drives the DC motor (9) in accordance with the torque signal (T) and the direction command signal (D), which is output from the AND circuit (40) only when the first and second direction signals (D1 and D2) coincide. Further, the microcomputers (4B and 24B) output first and second fail-safe relay energization signals (F1 and F2), respectively, when the power steering control system and the anti-skid braking system are judged to be operating normally. The power supply control circuit (42) immediately opens the fail-safe relay unit (6B) when neither the first and second signals (F1 and F2) are supplied. However, in the case where only one of the first and second signals (F1 and F2) are supplied, the power supply control circuit (42) defers the interruption of the fail-safe relay unit (6B) until the vehicle stops.

摘要： An ultrasonic obstacle sensor for sensing an obstacle on a road surface is disclosed which projects ultrasonic waves in the form of pulses toward the forwardly distant surface of a road in a downwardly inclined forward direction, and which is able to discriminate an obstacle on the road surface through reflection waves therefrom in a most effective and reliable manner. To this end, a timing instructor intermittently generates an instruction signal, based on which ultrasonic waves are generated. An ultrasonic transmitter projects the ultrasonic waves thus generated toward a road surface, and the reflected waves therefrom are received by an ultrasonic receier which in turn generates a reception signal. A reception signal processor AM detects the reception signal to provide an AM modulation signal. A time calculator calculates a time elapsing from the generation of the instruction signal. A discrimination signal generator generates a discrimination signal having an intensity which increases before the lapse of a predetermined time from the time of generation of the instruction signal, and decreases thereafter. A comparison circuit makes a comparison between the AM modulation signal and the discrimination signal to generate an output signal representative of the presence or absence of an obstacle on the road surface.

摘要： A suspension control apparatus and a method for a vehicle having a plurality of suspension units each disposed between a road wheel and the body of a vehicle for suspending the corresponding road wheel from the vehicle body. The suspension control apparatus includes a control unit which is connected to receive the output signals from an acceleration sensor, a vehicle-speed sensor and a steering sensor for calculating the rolling state of the vehicle due to a transverse acceleration thereof and controlling the respective suspension units based on the calculated rolling state of the vehicle so as to suppress the rolling thereof. The control unit serves to determine the period or frequency of change or reversal of the direction of the detected transverse acceleration of the vehicle, and control the suspension units so as to stop the roll-suppression control when the frequency of reversal exceeds a prescribed level. The control unit further performs the first roll-suppression control operation and stop subsequent roll-suppression control operations from the instant when the frequency of reversal of the direction of the transverse acceleration exceeds the prescribed level.
