| description | The present invention relates to a traction control method for a vehicle. The purpose of the present invention is to provide the traction control method for a vehicle, capable of preventing generation of excessive wheel slip and overheating of a dual clutch transmission (DCT) at same time when a driver controls an acceleration pedal and preventing existing weaving of the vehicle due to a DCT protection logic among traction control (TCS control). Also, the traction control method for a vehicle can obtain improved oscillation performance of the vehicle. To achieve the purpose of the present invention, the traction control method for a vehicle includes: a step of determining whether to satisfy a traction control entry condition predetermined based on vehicle driving state information including wheel speed information sensed by a wheel speed sensor after the acceleration pedal is input by a driver; a step of comparing a DCT temperature sensed by a temperature sensor to a setting temperature in case that it is determined that the predetermined traction control entry condition is satisfied; a step of determining whether reduction of engine torque in traction control is necessary in case that it is determined that an abnormal condition is satisfied, wherein the abnormal condition is determined based on at least one or two or more pieces of information among current vehicle speed information, DCT output torque obtained by the sensor, and TCS requiring torque which is an aimed engine torque required when traction is controlled in case that the DCT temperature is under an over temperature condition exceeding a predetermined temperature; and a step of reducing the engine torque by a value in which a first torque offset value is reduced from a normal condition setting value in the normal traction control in case that it is determined that the engine torque reduction is necessary.
본 발명은 차량의 트랙션 제어 방법에 관한 것으로서, 운전자의 가속페달 조작시 과도한 휠 슬립 발생과 DCT 과열을 동시에 방지할 수 있으면서도, 트랙션 제어(TCS 제어) 중 DCT 보호 로직으로 인한 종래의 차량 울컥거림을 방지하고, 차량의 개선된 발진 성능을 확보할 수 있도록 해주는 차량의 트랙션 제어 방법을 제공하는데 주된 목적이 있는 것이다. 상기한 목적을 달성하기 위해, 운전자 가속페달 입력 후, 휠속 센서에 의해 검출되는 휠속 정보를 포함하는 차량 운전 상태 정보에 기초하여 정해진 트랙션 제어 진입 조건을 만족하는지를 판단하는 단계; 상기 정해진 트랙션 제어 진입 조건을 만족하는 것으로 판단한 경우, 온도센서에 의해 검출된 DCT(Dual Clutch Transmission) 온도를 설정온도와 비교하는 단계; 상기 DCT 온도가 설정온도를 초과하는 과온 조건인 경우, 트랙션 제어시 요구되는 목표 엔진 토크인 TCS 요구 토크, 센서에 의해 취득되는 DCT 출력 토크, 및 현재 차속 정보 중 적어도 하나 또는 둘 이상의 정보로부터 정해진 비정상 조건을 만족하는 것으로 판단한 경우, 트랙션 제어시의 엔진 토크 감소가 필요한 조건인지를 판단하는 단계 |
