Abstract:
1. A transfer drive mode switching control system comprising: a shift actuator that switches from one of a plurality of drive mode positions of a transfer to the other; a drive mode position sensor that detects the drive mode position switched by the shift actuator and generates information regarding the drive mode position; a transfer control unit configured to be electrically connected to the drive mode position sensor and the shift actuator for outputting a control command signal based on the drive mode position information to the shift actuator and for controlling switching between the drive mode positions responsively to a driver-selected drive mode; and the transfer control unit allowing only a switching operation between predetermined two different drive mode positions corresponding to both ends of a working range of the shift actuator at which motion of the shift actuator is stopped mechanically, in presence of a failure in the drive mode position sensor.
