  • Patent number: 9428170
    Abstract: A vehicle driving device includes: a clutch that is provided between a driving shaft of an engine and an input shaft of a manual transmission and that connects the driving shaft and the input shaft to each other or disconnects the driving shaft and the input shaft from each other; a detection unit that detects an obstacle that is an obstacle to traveling of a host vehicle; a collision possibility determination unit that determines a possibility of collision between the obstacle and the host vehicle based on obstacle detection information detected by the detection unit; and a collision avoidance unit that, when the collision possibility determination unit determines that there is a possibility of collision with the obstacle, performs a fuel cut of the engine even if a rotation speed of the engine is less than an idling rotation speed.

  • Patent number: 9328783
    Abstract: A vehicle driving device includes: a clutch that is provided between a driving shaft of an engine and an input shaft of a manual transmission and that connects the driving shaft and the input shaft to each other or disconnects the driving shaft and the input shaft from each other; a clutch torque changing unit that changes clutch torque between the driving shaft and the input shaft; a collision possibility determination unit that determines a possibility of collision between an obstacle and a host vehicle; and a collision avoidance unit that gives an instruction to the clutch torque changing unit so as to avoid collision with the obstacle when the collision possibility determination unit determines that there is a possibility of collision with the obstacle.

  • Patent number: 7203587
    Abstract: A shift lever operating position judging device includes a position sensor having switches. Each switch is arranged to be at an ON state within a different range in a shift lever operating range, and two or three switches out of the plurality of switches are at the ON state in a different combination in response to each shift lever operating position. The device further includes a calculated value calculating means reading a sensor signal representing the ON or OFF state of the switches and calculating a calculated value based upon the signal, and a first operating position judging means for judging the shift lever position corresponding to the calculated value following a first operating position judgment reference defining the calculated value at the event that all of the plurality of switches have been at a normal condition.
