Abstract

본 발명은 차량의 각 휠에 설치된 휠 속도 센서를 사용하는 ABS를 이용하여 전자 제어 현가(ECS; Electronic Control Suspension)를 수행하는 방법으로서, 각각의 휠 속도 센서의 출력 신호를 받아 각 신호에 대해 적분을 수행하는 단계; 적분한 값들을 사용하여 각각 거친 정도(roughness) 값을 산출하는 단계; 및 산출된 거친 정도값을 소정의 임계치와 비교하는 단계; 비교 단계로부터 거친 도로로 판정된 경우 ABS(ABS; Antilock Braking System) 작동시 각각의 휠 제동 제어를 행하는 것을 특징으로 한다. 따라서 ESC 및 ABS 장착 차량의 경우 종래의 중력 센서를 사용하지 않아 경제적이다.The present invention is a method for performing Electronic Control Suspension (ECS) using ABS using a wheel speed sensor installed on each wheel of a vehicle, receiving an output signal of each wheel speed sensor and integrating the signals for each signal. Performing; Calculating roughness values using the integrated values, respectively; And comparing the calculated roughness value with a predetermined threshold; When it is determined that the road is rough from the comparison step, each wheel braking control is performed during ABS (ABS; Antilock Braking System) operation. Therefore, ESC and ABS equipped vehicle is economical because it does not use a conventional gravity sensor.
