Abstract
A shifting system for a motor vehicle transmission shifts the transmission into the neutral and returns a steering column shift lever to the neutral position from the reverse position, when the vehicle speed is above a pre-determined positive value and the shift lever is shifted into the reverse position. The system may further shift the transmission into the neutral and returns the steering column shift lever to the neutral position from the forward drive position, when vehicle speed is below a pre-determined negative value and the shift lever is shifted into the forward drive position.
Claims20
A shifting system for a motor vehicle transmission, comprising:
- a steering column shift lever which can be moved along a direction at least into
- a stable forward drive position,
- a stable idling position, and
- a stable reverse gear position;
- and
- wherein these positions are detectable for the operation of the motor vehicle transmission, and the steering column shift lever is automatically movable into the idling position.
A shifting system for a motor vehicle transmission having a forward drive, a neutral, and a reverse, the shifting system comprising:
- a steering column shift lever having
- a forward drive position,
- a neutral position, and
- a reverse position;
- and
- wherein these positions are detectable for the operation of the motor vehicle transmission, and wherein when vehicle speed is above a pre-determined positive value and the shift lever is shifted into the reverse position, the transmission is blocked from moving into the reverse, and the steering column shift lever is automatically shifted into the neutral position from the reverse position.
A shifting system for a motor vehicle transmission having a forward drive, a neutral, and a reverse, the shifting system comprising:
- a steering column shift lever having
- a forward drive position,
- a neutral position, and
- a reverse position;
- and
- wherein these positions are detectable for the operation of the motor vehicle transmission, and when vehicle speed is below a pre-determined negative value and the shift lever is shifted into the forward drive position, the transmission is blocked from moving into the forward drive, and the steering column shift lever is automatically shifted into the neutral position from the forward drive position.
A method for controlling a shifting system for a motor vehicle transmission, the method comprising:
- shifting the transmission into a neutral of the transmission and returning a steering column shift lever to a neutral position of the steering column shift lever from a reverse position of the steering column shift lever, when vehicle speed is above a pre-determined positive value and the shift lever is shifted into the reverse position.
A method for controlling a shifting system for a motor vehicle transmission, the method comprising:
- shifting the transmission into a neutral of the transmission and returning a steering column shift lever to a neutral position of the steering column shift lever from a forward drive position of the steering column shift lever, when vehicle speed is below a pre-determined negative value and the shift lever is shifted into the forward drive position.
