    摘要: In a brake control system for yaw control in a vehicle, the conditions for starting a brake operation are that the absolute value of a deviation between a target yaw rate determined in a target yaw rate determining device and an actual yaw rate detected by a yaw rate detecting device is equal to or greater than a preset deviation value and that the absolute yaw rate is equal to or greater than a preset value. The wheel brake for an outer wheel, during turning of the vehicle, is operated by the yaw control system based on the deviation between both the yaw rates. However, brake control does not occur when both of the yaw rates are the same in direction and are large. Thus, yaw control is conducted immediately when necessary, but the conduction of unnecessary yaw control is avoided, thereby reducing the frequency of the brake operation.

    摘要: An anti-lock control method for a vehicle includes the steps of: calculating an operation control quantity on the basis of a braking pressure at the start of an anti-lock control when a wheel is about to be locked during braking, and controlling the operation of an actuator, capable of adjusting the braking force of a wheel brake by the operation control quantity in order to reduce the braking force. In this process, the braking pressure at the start of anti-lock control is corrected with the locking tendency of the wheel to set an adjusted reference braking pressure, and the operation control quantity is calculated on the basis of the adjusted reference braking pressure. Thus, it is possible to determine the reference braking pressure with good accuracy, leading to an enhanced accuracy of the anti-lock control.
