  • Publication number: 20070188015
    Abstract: A vehicle brake control device determines a first duty factor required to achieve a stable rotational speed of motors and a second duty factor required to achieve a change rate of a target wheel cylinder pressure. The vehicle brake control device selects the larger one of the determined duty factors as a for-use motor duty factor to be used in outputting currents to the motors. Therefore, with the stable rotational speed and the change rate of the target wheel cylinder pressure, it is possible to achieve quick response to a request for braking made by a driver while suppressing the electric energy consumption of the motors.

  • Patent number: 7240972
    Abstract: A brake torque control device obtains inertia torque Tine based upon an equation of motion (Tine=Tw?Ft·Rt) about the rotation of a tire based upon a wheel torque Tw according to a brake torque exerted on the tire, road friction force Ft and a radius Rt of the tire. When the inertia torque Tine exceeds a predetermined reference value, road friction force Ft at this time is set as estimated maximum road friction force Fmax. The instructed brake torque is calculated under the condition that the value that is obtained by adding the predetermined value corresponding to the inertia torque Tine to the torque Fmax·Rt based upon this estimated maximum road friction force Fmax is set as an upper limit value of the instructed brake torque. This allows to clearly set, as one value, the target value of the instructed brake torque upon an ABS control, thereby being capable of more accurately executing the pressure-increasing control and pressure-reducing control of the brake fluid pressure.

  • Patent number: 7212903
    Abstract: A vehicle motion control apparatus is provided with an anti-skid control device and a steering angle adjusting device, which adjusts the steering angle of at least one of the front and rear wheels to cancel a yaw deviation between a desired yaw factor and an actual yaw factor, to be substantially zero. An incompatibility between the devices is determined on the basis of a state of the wheel adjusted by the steering angle adjusting device to cancel the yaw deviation. And, a predetermined parameter provided between a vehicle stability directive parameter and a brake directive parameter is set on the basis of the incompatibility. Then, the anti-skid control device controls the braking force applied to each wheel of the vehicle on the basis of the predetermined parameter. Consequently, the anti-skid control giving importance to the braking force can be performed, as long as the steering angle adjusting device is operative.

  • Patent number: 7164974
    Abstract: In vehicle roll sensing of the present invention, a self-aligning torque (SAT) estimator estimates a composite value of SATs generated on tire contact patch of right and left wheels. A slip angle computer detects a vehicle speed and a steering angle and computes a slip angle of the wheel from the measured vehicle speed and steering angle. An SAT model value computer estimates an SAT model value as a composite value of SATs of the right and left wheels when no load shifts between the right and left wheels on the basis of the slip angle. A load shift ratio estimator estimates a load shift state of the right and left wheels on the basis of the composite value of the SATs of the wheels and the SAT model value. A vehicle rollover estimator estimates a rollover of the vehicle on the basis of the estimated load-shift state.

  • Publication number: 20050080532
    Abstract: A steering control apparatus obtains a steered amount by which a steered wheel is steered based on a left-and-right braking force difference control amount, a vehicle state control amount, and a steering control amount. The apparatus changes the magnitude of the braking force difference control amount and the magnitude of the vehicle state control amount according to a vehicle speed or to time elapsed from when braking started to be applied to the left and right wheels. Accordingly, the vehicle driving on ?-split road is prevented from being deflected toward a side of higher friction coefficient due to the left-and-right braking force difference when the braking is applied.
