An ABS control system using a vertical acceleration sensor is provided to increase wheel slip by installing a vertical drag force calculating block for calculating the vertical drag force of a wheel for a road surface via a vertical acceleration signal. An ABS control system using a vertical acceleration sensor comprises plural sensors(12,14), an ABS controller(20) processing a signal from the plural sensors, and an actuator(30) driven by a driving signal of the ABS controller. The controller consists of a receiving block(21), a vertical drag force calculating block(24), a critical dimension setting block(26), and a comparing block(27). The receiving block receives a vertical acceleration signal in braking of a vehicle from a vertical acceleration sensor(32). The vertical drag force calculating block calculates the vertical drag force of a wheel for a road surface by using the vertical acceleration signal received. The critical dimension setting block changes the wheel slip rate acceleration value by using the vertical drag force calculated. The comparing block determines the wheel slip controlling condition of the vehicle by comparing the changed wheel slip rate acceleration value with the wheel slip rate. The vertical acceleration sensor installed at a suspension device is an up/down G sensor to control the damping force in a damper. |
