To provide a vehicle drive device capable of effectively driving a vehicle by using in-wheel motors without falling into the vicious cycle between enhancement of driving via the motors and an increase in vehicle weight. The present invention is a vehicle drive device that uses in-wheel motors to drive a vehicle and includes in-wheel motors (20) that are provided in wheels (2b) of a vehicle (1) and drive the wheels, a body side motor (16) that is provided in a body of the vehicle and drives the wheels of the vehicle, and a battery (18) and a capacitor (22) that supply electric power for driving the in-wheel motors and/or the body side motor, in which a voltage of the battery is applied to the body side motor and a voltage of the battery and the capacitor connected in series is applied to the in-wheel motors.

A vehicle drive device uses in-wheel motors to drive a vehicle and includes in-wheel motors that are provided in wheels of a vehicle and drive the wheels, a body side motor that is provided in a body of the vehicle and drives the wheels, and a controller that controls the in-wheel motors and the body side motor based on requested output power of a driver, in which the controller causes the body side motor to generate a driving force and the in-wheel motors not to generate driving forces when the requested output power of the driver is less than predetermined output power and the controller causes the body side motor and the in-wheel motors to generate driving forces when the requested output power of the driver is equal to or more than the predetermined output power.

Disclosed is an electric vehicle with an architecture suitable for an electro- hydraulic propulsion that decouples the drive to allow greater freedom in the location of the major components for different types of vehicles and achieve optimal weight distribution and low centre of gravity. This brings fourth significant improvements in vehicle dynamics that improve basic performance driven by a lower centre of gravity and reduced polar moment which improves stability, braking, road holding and reduced tyre wear. The improvements increase basic corner speeds to the limit.

A hybrid driving apparatus includes an internal combustion engine, a motive power transmission mechanism transmitting a driving force to main driving wheels, a main driving electric motor generating a driving force of the main driving wheels, an accumulator, subdriving electric motors generating driving forces of sub-driving wheels, and a control apparatus executing an electric motor traveling mode and an internal combustion engine traveling mode. The sub-driving electric motor is provided to each of the sub-driving wheels, the control apparatus causes only the main driving electric motor to generate the driving force in the electric motor traveling mode and causes the main driving electric motor and the sub-driving electric motors to generate the driving forces in acceleration of the vehicle at a predetermined vehicle speed or higher, and although the engine generates the driving force, it does not cause the motors to generate driving forces in the traveling mode.

A power storage module comprises: a frame body; a plurality of power storage cells accommodated in the frame body; a bridging portion that is provided inside the frame body and connects an upper portion and a lower portion of the frame body to each other; and two flange portions that are provided outside the frame body and project in directions opposite to each other. The two flange portions are located above a central portion of the frame body in a height direction.

An electric vehicle includes a chassis and a seat assembly that includes a plurality of seats mounted to the chassis. The chassis includes a vehicle frame defining a mounting space, and a battery module disposed in the mounting space and including an outer battery unit that is mounted to the vehicle frame, and an inner battery unit that is coupled to the outer battery unit. The vehicle frame is operable to switch between an expanded state, where the inner battery unit is permitted to be coupled to the outer battery unit and the seats are spaced apart from each other, and a collapsed state, where the inner battery unit is prevented from being coupled to the outer battery unit and the seats are overlapped with each other.

The fixing member includes a lower contact member 32 and an upper contact member (contact members) that come in contact with a battery to support the battery between a driver seat and a passenger seat (vehicle seats), and the lower contact member and the upper contact member are deformed when a load of a predetermined value or more is input from a vehicle width direction, to allow movement of the battery in the vehicle width direction.

A vehicle floor structure is provided including: a vehicle interior opening formation section provided inside a vehicle cabin, and demarcating a vehicle interior opening that opens into the vehicle cabin; a vehicle exterior opening formation section provided further toward a vehicle lower side than a floor inside the vehicle cabin, and demarcating a vehicle exterior opening that opens toward a vehicle exterior; a storage section provided at the vehicle lower side of the floor, and demarcating a storage space that connects the vehicle interior opening and the vehicle exterior opening together; and a pull-out receptacle disposed inside the storage section at a position corresponding to the vehicle interior opening, and capable of moving from inside the storage section to the vehicle exterior through the vehicle exterior opening.

A battery device for a vehicle, which can be miniaturized while including ancillary instruments such as a relay device. The battery device is mounted in a lower portion of a vehicle, and including a battery case; a plurality of battery modules accommodated in the battery case and arranged such that at least some of the battery modules are stacked in a plurality of levels; and a first relay device that switches connection and disconnection between external electric devices and the battery modules. The first relay device is disposed on a side in a vehicle width direction of a portion where the battery modules are stacked in a plurality of levels.

An assembly for a hybrid motor vehicle, in particular a partially electrified hybrid motor vehicle, having a vehicle battery and a vehicle seat comprising a seat surface. The vehicle seat is connected or connectable to a vehicle floor of the hybrid motor vehicle by means of a substructure having at least two seat rails. The vehicle battery is arranged or arrangeable beneath the vehicle seat and above the vehicle floor. The vehicle battery is held on the vehicle seat by means of a suspension means attached to the top side, or in an upper region, of the vehicle battery.
