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 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;
• 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;
• a speed detection unit that detects a speed of the vehicle;
• a clutch torque changing unit that changes clutch torque between the driving shaft and the input shaft;
• and
• an engine restart unit that restarts the engine after disengaging the clutch by the clutch torque changing unit when the engine is stopped by the fuel cut.
