Claims (9)
- 주행 동역학적 한계 상황에서 차량(14) 운전자를 보조하기 위한 방법에 있어서,주행 동역학적으로 임계 상황에서, 운전자가 차량을 다시 안정화하기 위해 어느 방향으로 조향해야 하는 지를 인식할 수 있도록 조향 휠(13)에 대해 모멘트(M)가 작용하고,목표 요잉율(dΨsoll/dt)은 모멘트(M)의 도입 중에 고정값으로 유지되고, 그 다음 미리 주어진 안정화 기준이 충족된 경우에야 비로소 다시 목표 요잉율(dΨsoll/dt)의 새로운 값이 계산되는 것을 특징으로 하는 방법.
- 제1항에 있어서, 모멘트(M)는, 운전자가 모멘트(M)의 방향과 반대의 방향으로 조향 휠(13)을 조작할 때 운전자에 의해 극복될 수 있는 값으로 제한되는 것을 특징으로 하는 방법.
- 제1항 또는 제2항에 있어서, 모멘트(M)는 실제 요잉율(dΨist/dt)의 구배가 미리 주어진 임계값 미만이면 감소되는 것을 특징으로 하는 방법.
- 제1항 또는 제2항에 있어서, 설정된 조향 모멘트(M)의 크기는 목표 요잉율(dΨsoll/dt) 또는 조절 편차의 함수인 것을 특징으로 하는 방법.
- 제3항에 있어서, 실제 요잉율(dΨist/dt)과 목표 요잉율(dΨsoll/dt) 사이의 편차가 미리 주어진 임계값보다 크고 실제 요잉율(dΨist/dt)의 구배가 미리 주어진 임계값을 초과하면, 상기 모멘트(M)와는 다른 모멘트의 개입이 이루어지는 것을 특징으로 하는 방법.
- 삭제
- 주행 동역학적 한계 상황에서 차량(14) 운전자를 보조하기 위한 장치에 있어서,- 주행 동역학적 한계 상황을 인식하기 위한 센서(2 - 7, 11)와,- 주행 동역학적 한계 상황에서 조향 휠(13)에 대해 모멘트(M)를 도입하기 위한 액츄에이터(9)를 포함하고,목표 요잉율(dΨsoll/dt)은 모멘트(M)의 도입 중에 고정값으로 유지되고, 그 다음 미리 주어진 안정화 기준이 충족된 경우에야 비로소 다시 목표 요잉율(dΨsoll/dt)의 새로운 값이 계산되는 것을 특징으로 하는 장치.
- 제7항에 있어서, 모멘트(M)는 실제 요잉율(dΨist/dt)의 구배가 미리 주어진 임계값 미만이면 감소되는 것을 특징으로 하는 장치.
- 제7항 또는 제8항에 있어서, 실제 요잉율(dΨist/dt)과 목표 요잉율(dΨsoll/dt) 사이의 편차가 미리 주어진 임계값보다 크고 실제 요잉율(dΨist/dt)의 구배 가 미리 주어진 임계값을 초과하면, 다른 보조 모멘트 개입이 수행되는 것을 특징으로 하는 장치.
