Abstract:
1. A vehicle including a first motor, a second motor, and an engine as drive sources, the vehicle comprising: a mechanical pump that discharges oil using power from the engine; an electric pump that discharges oil using electricity; a first oil passage for supplying oil discharged from at least one of the mechanical pump and the electric pump to the first motor; a second oil passage for supplying oil discharged from at least one of the mechanical pump and the electric pump to the second motor; a switch-over valve provided on the first oil passage and capable of switching over to any of a first state in which the oil flowing through the first oil passage is allowed to be supplied to the first motor and a second state in which the oil flowing through the first oil passage is not allowed to be supplied to the first motor; and a switch control valve that outputs hydraulic pressure to the switch-over valve, the switch-over valve being configured to switch over to any of the first state and the second state in accordance with hydraulic pressure from the switch control valve and hydraulic pressure from the mechanical pump, wherein the switch control valve is a solenoid valve, the vehicle further comprises a pressure regulating valve that regulates the hydraulic pressure from the mechanical pump and outputs the regulated hydraulic pressure to the switch-over valve, and the switch-over valve is configured to switch over to any of the first state and the second state in accordance with hydraulic pressure from the solenoid valve and hydraulic pressure from the pressure regulating valve, wherein the switch-over valve is configured to enter the first state if hydraulic pressure from the solenoid valve is not inputted when hydraulic pressure from the pressure regulating valve is not inputted, and to enter the second state if hydraulic pressure from the solenoid valve is inputted when hydraulic pressure from the pressure regulating valve is not inputted, and to enter the first state regardless of whether or not hydraulic pressure from the solenoid valve is inputted when hydraulic pressure from the pressure regulating valve is inputted.
