Patent ID: 8706376

Claim:
An ABS control system that controls wheel brake pressure, the ABS control system including: a wheel speed sensor; a brake pressure sensor; an electronic control unit configured to receive signals from the wheel speed sensor and the brake pressure sensor, the electronic control unit including a software having a calibration mode and an ABS control mode; wherein when an actual vehicle test is performed using a vehicle equipped with said ABS control system and the calibration mode thereof, the wheel speed sensor and the brake pressure sensor measure wheel speed and brake pressure during ABS braking in the actual vehicle test, and the electronic control unit automatically calibrates a parameter of the software having the calibration mode and the ABS control mode in response to the wheel speed and brake pressure measurement results; and wherein the ABS control system automatically calibrates the internal parameter used in ABS control mode by further (b) judging whether or not the calculated internal parameter satisfies a predetermined condition and (c) ending calibration if it is judged that the calculated internal parameter satisfies the predetermined condition and again executing the procedure of (a) and (b) if it is judged that the calculated internal parameter does not satisfy the predetermined condition.
