Abstract:
1. A vehicle driving apparatus, comprising: an engine; a motor for starting the engine; a driveshaft for receiving torque from the engine and driving wheels of the vehicle; a parking lock mechanism for locking the driveshaft; a brake device for locking the wheels; a controller for controlling the motor, the parking lock mechanism, and the brake device; and a temperature sensor that measures temperature of a coolant of the engine, wherein in response to satisfaction of a condition for starting the engine, the controller executes a lock switching control in which the wheels are forcibly locked by the brake device and the parking lock mechanism is released to unlock the driveshaft, and then the controller executes a cranking control in which the engine is started by the motor, wherein the controller locks the driveshaft using the parking lock mechanism and cancels the forcible locking of the wheels by the brake device in response to when the engine starts self-driving after the cranking control, wherein the controller executes the cranking control after the lock switching control if the temperature detected by the temperature sensor is lower than a predetermined temperature, and the controller executes the cranking control without executing the lock switching control if the temperature detected by the temperature sensor is higher than the predetermined temperature.
