Abstract: Systems and methods for balancing levels of liquid fuel among multiple vehicle-mounted fuel tanks utilize at least one control valve that is configured to admit pressurized gas into a first fuel tank while a second fuel tank is ventilated, responsive to detection of a difference of liquid fuel levels within the first and second fuel tanks. Admission of pressurized gas into one fuel tank and ventilation of another fuel tank creates a pressure imbalance that causes liquid fuel to flow through a balancing line connecting the fuel tanks. Balancing may be performed in a bidirectional manner.

Abstract: The power steering device is configured to: apply a required assist force only from a first electric motor until a predetermined period elapses, which is a period from a time point at which a driver starts steering to a time point at which a second-electric-motor drive start condition, which is a condition for starting drive of a second electric motor, is satisfied; when the predetermined period has elapsed, apply the required assist force from the first electric motor and a hydraulic actuator; and adjust an assist force by the first electric motor so that the assist force by the first electric motor is a value obtained by subtracting an assist force by the hydraulic actuator from the required assist force. As a result, the device can be downsized, and a sufficient required assist force can be generated from an initial stage of the steering.
