A vehicle driving system having a clutch actuator and gear shifting device that use motors is provided. A clutch is disengaged and engaged and gear shifting is conducted at high speeds. The clutch actuator drives the clutch and includes a motion converting mechanism and two motors. The motion converting mechanism is a mechanism for converting rotary motion to linear motion and for applying an operating force to the clutch. The two motors are for applying a rotating force to the motion converting mechanism. The gear shifting automatically shifts gears by driving a transmission rack of a transmission and includes a ball screw mechanism and two motors. The ball screw mechanism is a mechanism for converting rotary motion to linear motion and for applying an operating force to the transmission. The two motors are for applying a rotating force to the ball screw mechanism.
