    摘要: An electrically driven power steering apparatus develops an assisting steering force to be applied to a steering system in accordance with a driving force detected, by detecting a driving force which is applied to a steering system from steering means and allowing an electric motor of an electric drive mechanism to be energized at a higher power level when the driving force detected is of an increased magnitude and at a reduced power level when the detected driving force is of a reduced magnitude. A voltage output from an onboard power supply is monitored, and when the voltage is below a given value, the motor is energized at a power level which is less than the energization power level which corresponds to the detected driving force. In this manner, a degradation of the onboard battery is prevented which would result from the operation of the electrically driven power steering apparatus when the battery voltage is low or when the charging power is insufficient. The energizing power level applied to the motor is limited by two alternative methods. In one method, the energization of the motor above an upper limit of energization power level is inhibited. In a second method, a lower limit is established for a response driving force, and the energization of the motor is inhibited in response to a driving force which is below the lower limit.

    摘要: A control of a vehicle motion control device 10 is as follows during an oversteer restraining control. Specifically, when tire inflation pressure is appropriate, the device sets braking force exerted on each of front and rear wheels at the outer side of the turning direction so as to be reference braking forces Ff1 and Fr1, that are generated when an absolute value of a lateral acceleration deviation ΔGy is not less than a reference value a1 and that respectively increase up to an upper limit value ff and upper limit value fr in accordance with the increase in the absolute value of the lateral acceleration deviation ΔGy. On the other hand, when a tire inflation pressure of one of the front and rear wheels at the outer side of the turning direction is lowered, the device sets the braking force, such that the braking force starts to be generated from when the absolute value of the lateral acceleration deviation ΔGy is smaller than the reference value a1 by an amount in accordance with the reduction in the tire inflation pressure and that the upper limit value of the braking force with respect to the wheel whose tire inflation pressure is lowered is decreased by an amount in accordance with the reduction in the tire inflation pressure and that the upper limit value of the braking force with respect to the wheel that is not the wheel whose tire inflation pressure is lowered is increased by an amount in accordance with the reduction in the tire inflation pressure.

    摘要: An object is to simplify the structure of electric wirings, and to facilitate installation. A vehicular motion quantity sensor and a steering angle sensor are installed in the same casing or mechanically connected directly with the casing. Therefore, it is possible to put together electrical wiring harnesses for transmitting the detection signals from the vehicular motion quantity sensor and the steering angle sensor to an ECU. Moreover, since all of the sensors can be located in the same compartment, the structure of the electrical wiring harnesses can be simplified and can be installed more easily.

    摘要: A motion control device 10 for a vehicle exerts braking force only on the rear wheel at the inner side of the turning direction for generating a yawing moment on the vehicle only in the turning direction of the vehicle when an absolute value of an actual lateral acceleration Gy is not more than a value Gyth, i.e., when there is a small possibility of the occurrence of an excessive roll angle on the vehicle body, in case where the turning state of the vehicle is the understeer state. On the other hand, it exerts braking force not only on the rear wheel at the inner side of the turning direction, but also on the front and rear wheels at the outer side of the turning direction for generating a yawing moment in the direction opposite to the turning direction too, when the absolute value of the actual lateral acceleration Gy exceeds the value Gyth, i.e., when there is a great possibility of the occurrence of the excessive roll angle on the vehicle body, in case where the turning state of the vehicle is the understeer state.

    摘要: A vehicle motion control device reduces noise resulting from operation of a vacuum booster when an automatic pressure control is performed by properly controlling the energization of a linear solenoid of a booster actuator. An automatic hydraulic pressure generator is controlled in accordance with the vehicle motion condition and a hydraulic pressure control valve device is controlled to perform the automatic pressure control. A target electric current of the linear solenoid for actuating the vacuum booster is instantaneously increased to a starting target value which corresponds to an electric current value immediately before starting the operation of the vacuum booster and which is less than a maximum value of the target electric current, and then is gradually increased approximately to the maximum value of the target electric current.

    摘要: The present invention is directed to an apparatus for determining a state of braking operation of a vehicle. Wheel speed sensors are provided for detecting wheel speeds of a front wheel and a rear wheel. A wheel speed difference is calculated between the wheel speed of the front wheel and the wheel speed of the rear wheel detected by the wheel speed sensors. A braking operation detection device is provided for detecting an operation of a brake pedal. Based upon the calculated wheel speed difference and the operation of the brake pedal detected by the braking operation detection device, it is determined whether the brake pedal was rapidly depressed. In accordance with this result, and in response to the wheel speeds detected by the wheel speed sensors, the braking force applied to the front wheel can be adjusted in a predetermined relationship with the braking force applied to the rear wheel.

    摘要: The present invention is directed to a braking force control system for an automotive vehicle having a hydraulic braking pressure control apparatus which is provided for applying the braking force to each of front and rear wheels of the vehicle at least in response to depression of a brake pedal. A desired yaw rate is set in accordance with a motion of the vehicle, and an actual yaw rate of the vehicle is measured. A varying rate of the desired yaw rate is calculated, and a varying rate of the actual yaw rate is calculated. Then, a deviation between the varying rate of the desired yaw rate and the varying rate of the actual yaw rate is calculated. And, a limitation unit is provided for actuating the hydraulic braking pressure control apparatus to limit the varying rate of the actual yaw rate by applying the braking force to at least one of the wheels, when the deviation exceeds a predetermined value. The limitation unit may be so constituted as to apply the braking force to a front wheel of the wheels which is located on the outside of a curve in the vehicle's path.
