Vehicle driving device

A vehicle driving device comprising:

• 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;
• 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;
• wherein, when the collision possibility determination unit determines that there is a possibility of collision with the obstacle, the collision avoidance unit instructs the clutch torque changing unit to reduce the clutch torque from a current value;
• and
• wherein, when the collision avoidance unit determines that collision is not avoidable just by reducing the clutch torque, the collision avoidance unit instructs the engine to generate an engine brake in a state where the clutch is engaged.
