Lane departure prevention system of vehicle

A lane departure prevention system includes a controller configured to control a braking force of vehicle wheels such that a lane departure prevention yaw moment is applied to a vehicle. The controller determines whether there is a likelihood that the vehicle enters a spinning state based on at least one of a difference between an actual yaw rate and a normative yaw rate of the vehicle calculated based on a steering angle, a vehicle speed, and the lane departure prevention yaw moment, and a degree of braking slip of a turning inside wheel when the lane departure prevention yaw moment is a yaw moment for preventing departure of the vehicle from a lane to a turning outside, and applies a spin prevention yaw moment to the vehicle when it is determined that there is a likelihood that the vehicle will enter the spinning state.

Vehicle antilock brake system control device

A wheeled vehicle's antilock brake system (ABS) control device has three kinds of control modes of a braking force oriented mode, a sideways force oriented swinging-motion suppression mode and a sideways force oriented swinging-motion enhancement mode each of which is an ABS control mode being selected by means of an ABS control mode selection unit; and the vehicle ABS control device is so arranged that, in accordance with an ABS control mode selected by the ABS control mode selection unit, target slip rates on each of the vehicle's wheels being set by a target slip-rate setting unit are transferred toward respective braking force orientation or sideways force orientation, thereby the behavior of a wheeled vehicle is stabilized at a time when the wheeled vehicle on which the vehicle ABS control device is mounted makes a turn.

This vehicle braking control device executes automatic braking control to adjust a braking torque on the basis of a vehicle target deceleration value corresponding to a distance between the vehicle and an object in front of the vehicle, and executes anti-skid control to suppress excessive wheel slip by adjusting the braking torque on the basis of a wheel speed. The braking control device calculates an actual deceleration value corresponding to the target deceleration value, and executes feedback control on the basis of the target deceleration value and the actual deceleration value such that the actual deceleration value approaches the target deceleration value. The configuration is such that a control gain of the feedback control is reduced when anti-skid control is executed. Further, the configuration may be such that execution of feedback control is prohibited when anti-skid control is executed.
