摘要： In a stabilizer apparatus for a vehicle, an electronic control unit calculates a target current of an electric motor from vehicle speed, steering angle, and lateral acceleration, and increases and decreases actual current such that the calculated target current flows through the motor. The control unit decreases the actual current by a predetermined amount when the difference between the target current and the actual current becomes smaller than a predetermined value during control of increasing the actual current. The predetermined amount is equal to the difference between the determined target current at the time of the detection of the difference and current which is necessary to obtain, during control of decreasing the actual current, an output torque equal to the output torque of the speed reduction mechanism obtained as a result of the target current flowing through the electric motor.

When a self-aligning torque estimating unit M6 estimates self-aligning torque generated in front wheels on the basis of detection result of the detecting unit, the quantity of influence of longitudinal force on self-aligning torque is removed on the basis of longitudinal force acting on the front wheels and estimated by a longitudinal force estimating unit M15 and a front wheel slip angle estimated by a front wheel slip angle estimating unit M9y. A grip factor estimating unit M12 estimates the grip factor of the front wheels on the basis of change in self-aligning torque in accordance with the side force.

摘要： The present invention is directed to a monitor system for use in an automotive vehicle which includes wheel brake cylinders operatively mounted on wheels, respectively, and which includes a hydraulic pressure control apparatus for generating a hydraulic braking pressure in response to depression of a brake pedal. A difference calculating unit calculates a difference between a wheel speed of a wheel to be determined and a wheel speed of at least one reference wheel which is compared with a predetermined value, when a braking operation detection unit detects a braking operation. Then, a determination unit compares the difference with a predetermined value, and determines that the pressure circuit provided for the wheel to be determined is normal, when the difference is lower than the predetermined value. An output unit may be provided to produce an output signal when a period of time during which the difference continues to be equal to or greater than the predetermined value, exceeds a predetermined time.

摘要： The steering stability of a moving vehicle is maintained by measuring an actual yaw rate of the vehicle and determining a desired yaw rate of the vehicle and producing an output signal in response to a comparison of the actual and desired yaw rates. The steering angle of steerable wheels of the vehicle is controlled in response to the output signal in a manner tending to substantially conform the actual yaw rate to the desired yaw rate, thereby maintaining vehicle stability. The steerable wheels are steered by a steering wheel, and are independently steered by a motor in response to the output signal. The amount of steering provided by the motor is controlled in dependence upon an estimated frictional coefficient between the vehicle and the road, or upon detected values of the environmental temperature and precipitation.
