Anti-lock Braking System (ABS) works by measuring the speed of each wheel through wheel speed sensors, receiving brake switch and other information, and judging the current road conditions through algorithms. The hydraulic control unit (HCU) controls the pressure adjustment of the brake, such as boosting, holding, and releasing, to prevent the wheel from locking up and maintain sufficient brake force. Through real-vehicle parameter tuning, the selected vehicle can achieve the required braking performance target. In terms of real-vehicle verification, the indigenous ABS performs better than major international brands on wet roads. At present, the parameter tuning of ABS for each vehicle type can be completed in Taiwan, which will greatly reduce the cost and promote the popularization of ABS installation, so that the number of traffic accidents can be significantly reduced. The control technology is also extended to three-wheel and four-wheel vehicles, in addition to two-wheel motorcycles.
