Abstract: A vehicle drive system includes a slip acquisition unit that acquires that an excessive slip of front wheels or rear wheels has occurred, an addition slip point calculating unit that calculates addition slip points in a time-discrete manner, based on the slip acquisition unit having acquired that the excessive slip has occurred, a cumulative slip point calculating unit that accumulates the addition slip points and calculates a cumulative slip point over time, a drive state switching unit that, switches between 2WD and AWD based on cumulative slip points, and an increase forbidding determination unit that forbids addition or accumulation of the addition slip points, or increase of the cumulative slip points, in a case where a lateral acceleration correlation value that has correlation with lateral acceleration of the vehicle exceeds a lateral acceleration threshold value.

Abstract: A slip determination system for a vehicle, which is capable of improving the determination accuracy by avoiding erroneous determination of excessive slip of wheels when a state of the wheels, driven/braked by motors, is switched. In the slip determination system according to the present invention, when first and second motor rotational speeds NMOT1 and NMOT2, which are rotational speeds of rear motors which brake/drive rear wheels WRL and WRR, reach a reference rotational speed NMREF set based on wheel rotational speeds NWFL, NWFR, NWRL, and NWRR, it is determined that excessive slip has occurred in the rear wheels WRL and WRR. When the sign of a target torque TROBJ of the rear motors is inverted, the reference rotational speed NMREF is changed to a value more difficult to be reached by the first and second motor rotational speeds NMOT1 and NMOT2, or the excessive slip determination is inhibited.

Abstract: A fuel shutoff valve is attached to the upper portion of a fuel tank and shuts off the communication between the inside of the fuel tank and a canister by opening and closing a vapor passage for communicating between the fuel tank and the canister. The fuel shutoff valve is configured with a first valve mechanism having a coil disposed on the inner periphery of a cylindrical valve chamber and a movable core, which enables to communicate between the fuel tank and the canister by lowering the level of the movable core, and a second valve mechanism which enables to communicate between the fuel tank and the outside thereof by shifting the level of the valve body which is disposed inside the movable core due to the pressure from the inside of the fuel tank or the outside thereof.

Abstract: Provided is a vehicle provided with left and right electric motors electrically connected to a battery and mechanically connected respectively to left and right vehicle wheels, a power generator mechanically connected to an internal combustion engine being electrically connected to the battery, wherein the battery is reliably protected during traction control and at other such times. Two electric motors, specifically first and second electric motors, are temporarily handled integrally to determine a torque down amount (TD), which is the total allowable power variation width (α) of the two electric motors, on the basis of left and right total power (Y), and the respective motive powers of the first and second electric motors are controlled while being limited by values obtained by simply dividing the determined torque down amount (TD) equally, whereby the allowable input/output power (allowable input power (Z)) of the battery is reliably protected.
