Abstract: In accordance with a vehicle motion control apparatus, a steering angle (θh) of a steering wheel is determined on the basis of a rotation angle (θpm) of an assist motor (24m) detected by a rotation angle sensor (24s) and a rotation angle (θvm) of a gear ratio variable motor (32m) detected by a rotation angle sensor (32s), and a VGRS control process (40a) of a gear ratio variable mechanism is executed on the basis of the determined steering angle (θh). Accordingly, since the steering angle (θh) of the steering wheel is determined on the basis of the rotation angle (θvm) used for the VGRS control process (40a) of the gear ratio variable mechanism and the rotation angle (θpm) used for an EPS control process (30a) of an EPS actuator, it is possible to obtain the steering angle (θh) of the steering wheel without a steering angle sensor. Therefore, it is possible to reduce the number of the parts of a vehicle motion control apparatus.

Abstract: The vehicle operation control apparatus multiplies the variable gain G controlled based on the vehicle velocity V, the steering angle &thgr;h, the steering angle velocity &ohgr;h and the actual steering angle &thgr;T with the steering angle &thgr;h, and controls the actual steering angle &thgr;T of the driven wheels on a result of this multiplication. Consequently, the additional turning time gear ratio Ga1 or the turning-back gear ratio Ga2, set up individually, can be selected depending on the turning direction of the steering wheel. Therefore, the steering feeling both at the time of additional turning and turning-back can be improved.

Abstract: The present invention relates to an antilock brake system having an electrically controlled hydrostatic motor and pump system. The inventive ABS improves stability and maneuverability during braking by reducing or eliminating vibration and noise problems due to conventional on/off solenoid valve control. In accordance with exemplary embodiments, a two position solenoid is actuated (i.e., energized) in response to initiation of an ABS control mode. Once activated, the solenoid remains energized for the duration of the ABS control mode. Because the solenoid remains continuously activated during the ABS control mode, the vibration and noise associated with repeatedly activating and deactivating a solenoid is reduced or eliminated. To effect pressure increases and decreases in a braking channel during the ABS control mode, a reversible (i.e., bi-directional) pump is provided in each braking channel. To further enhance the smoothness of the braking, the reversible pump is controlled with an analog command signal that is, for example, proportional to a difference between wheel deceleration/acceleration detected for the channel and a vehicle's deceleration/acceleration.

Abstract: 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 motor comprises a fluid motor. Additionally, valves are provided to stop the flow of fluid in the event that a malfunction occurs.

Abstract: A stability augmentation system and hydrostatic power steering system including an electric motor is provided for a automotive vehicle. The hydrostatic power steering system utilizes a power steering piston responsive to movement of the rack element of the rack and pinion steering connection. A torque sensor is connected to the steering shaft for providing an output torque signal to a power steering controller. The electric motor of the system is responsive to a command signal generated by the power steering controller. An electrically operated valve is connected to the hydraulic lines and is adapted to receive a signal from the power steering controller for controlling flow of hydraulic fluid to the power steering chamber. The electrically operated valve arrangement is rendered inoperative within a predetermined zone defined by the command signal and the output torque signal. The stability augmentation system includes a hydraulic system having a separate oil pump and electric motor. The motor is controlled by a stability augmentation system controller through inputs from a steering wheel angle sensor, vehicle speed sensor, yaw rate sensor and a position sensor.

Abstract: Based on a difference (ΔFb) between a target value (Fbt) and an actual value (Fba) of a friction member force for pressing a brake disc, a feedback energization amount (Ipt) is calculated using a proportional gain smaller than an ultimate sensitivity gain. If ΔFb falls within a fluctuation range of torque ripple, a first compensation energization amount (Ibt) is calculated using a proportional gain larger than the ultimate sensitivity gain, and if ΔFb falls outside the fluctuation range, the first compensation energization amount (Ibt) is calculated to be constant. A second compensation energization amount (Ift) is calculated based on a calculation characteristic that is preset based on a torque fluctuation over a predetermined range of an electric motor position and based on an actual position of the electric motor. An indication energization amount calculated according to Fbt is adjusted by Ipt, Ibt, and Ift to calculate a target energization amount.

Abstract: In a vehicle brake control device for generating rear wheel braking torque by an electric motor, “slip suppression control of the rear wheel” for reducing rear wheel braking torque by controlling the electric motor is executed based on a slip state quantity of the rear wheel. Further, “sudden-stop control” for rapidly stopping electric motor rotation motion is executed based on a slip state quantity of a front wheel. The sudden-stop control is executed when rear wheel slip suppression control is not being executed. As the sudden-stop control, “control for changing an energization amount of the electric motor stepwise to an energization limit value set in advance corresponding to a deceleration direction of the electric motor” may be executed. Accordingly, it is possible to suppress excessive rear wheel slip due to inertia influences or the like of the electric motor when execution of the rear wheel slip suppression control is started.
