Vehicle antilock brake system control device
4 Jul 23
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.
