Claims (11)
- 전달될 수 있는 최대 구동 토크를 식별하기 위한 수단과 그리고 차량과 도로의 표면 간의 마찰 계수를 결정하기 위한 수단을 구비하며, 전달될 수 있는 상기 최대 구동 토크는 식별된 마찰 계수의 함수로서 미리 결정되고 또한 출력 포크를 미리 결정된 최대 구동 토크로 제한하는 효과를 적어도 갖는 구동 유니트에 의해 토크 출력에 영향을 미치게 함으로써 설정되는 것을 특징으로 하는 견인력 제어 시스템.
- 제1항에 있어서, 전달될 수 있는 최대 구동 토크는 미끌림 의존성 마찰 계수와 그리고 주행 상황 및 도로 상황 각각에 따라 달라지는 상수에 따라 달라지는 것을 특징으로 하는 견인력 제어 시스템.
- 제2항에 있어서, 만곡부를 통과하는 주행과 만곡부를 진입하는 주행에 대해서 다른 상수가 차량의 차륜과 도로 사이의 마찰 계수의 함수로서 미리 결정되고 그리고/또는 차량이 불안정해질 때 미리 결정되는 것을 특징으로 하는 견인력 제어 시스템.
- 제1항에 있어서, 전달될 수 있는 최대 구동 토크는 증가된 미끌림 요건이 있는 경우에 정정되는 것을 특징으로 하는 견인력 제어 시스템.
- 상기 항들 중 어느 한 항에 있어서, 미끌림 의존성 마찰 계수가 구동 토크의 몫과 식별된 미끌림에 기초하여 증가된 미끌림 요건을 나타내는 값의 함수로서 계산되는 것을 특징으로 하는 견인력 제어 시스템.
- 제5항에 있어서, 추가적인 미끌림 요건에 대한 값은 차량의 속도에 따라 달라지고, 추가적인 미끌림 요건 값과 차량의 속도 간의 관계는 차량의 속도에 따라 달라지게 하는 것을 특징으로 하는 견인력 제어 시스템.
- 제5항에 있어서, 사용된 타이어의 종류 또는 타이어 혼합에 따라서 증가된 미끌림 요건을 검출하는 검출 수단을 마련하는 것을 특징으로 하는 견인력 제어 시스템.
- 제7항에 있어서, 설정된 차량 토크에 기초하여 계산된 부하 의존성 마찰 계수가 미리 결정된 시간 동안 계산된 미끌림 의존성 마찰 계수보다 큰 경우에는 증가된 미끌림 요건을 검출하는 것을 특징으로 하는 견인력 제어 시스템.
- 제7항에 있어서, 증가된 미끌림 요건이 타이어 혼합의 결과로서 검출된 경우 미끌림 요건과 차량의 속도 간 관계의 속도 의존성이 수정되는 것을 특징으로 하는 견인력 제어 시스템.
- 제 1항 내지 제4항 중 어느 한 항에 있어서, 차량의 구동륜이 헛도는 경향이 있는 경우에 구동륜의 미끌림은 구동 유니트에 의해 미리 결정된 소정의 토크를 미리 결정함으로써 견인력 제어의 부분으로서 미리 결정된 소정치로 조정되는 것을 특징로 하는 견인력 제어 시스템.
