The first projecting pieces each have a first pressure receiving surface, the second projecting pieces each have a second pressure receiving surface.

A vehicle drive device includes a control device, and the control device controls an electric motor, a first pressing mechanism and a second pressing mechanism such that a relational expression of T<T.sub.1+T.sub.2 is satisfied, where T represents a torque that is input to an input rotation member, T.sub.1 represents a maximum of a torque that is able to be transmitted by a first multi-disc clutch and T.sub.2 represents a maximum of a torque that is able to be transmitted by a second multi-disc clutch.

A vehicle drive device includes: an input shaft that receives a driving force of a driving source and that is provided with a first gear; an intermediate shaft that is provided with a second gear meshing with the first gear and a third gear located next to the second gear in a direction of a rotation axis and that is disposed in such a manner that the intermediate shaft is allowed to move in the direction of the rotation axis; an output shaft that is provided with a fourth gear meshing with the third gear; a first gear pair including the first and second gears; and a second gear pair including the third and fourth gears. One of the first gear pair and the second gear pair includes a helical gear, and the other of the first gear pair and the second gear pair includes a double helical gear.

A vehicle caravan comprising electric vehicles configured for coordinated movement and airflow control comprising: a lead vehicle and a chase vehicle, the lead vehicle disposed at the front of the caravan and the chase vehicle disposed behind the lead vehicle in a chase pattern. Each lead and chase vehicle comprising: a vehicle chassis and a front rotatable vehicle drive axle; a selectively movable electric propulsion motor comprising a rotatable motor shaft and a motor axis configured to be oriented in a substantially vertical direction; an air duct configured to direct an airflow to the propulsion motor; an airflow shutter in the front end of the air duct to selectively control the airflow within the air duct; and a vehicle controller; the caravan and the chase pattern configured for coordination of the motor position and the open/closed position of the lead vehicle and the chase vehicle shutters while the caravan is moving.

A vehicle includes a primary axle powered by an actuator and a secondary axle powered by a motor. The secondary axle includes a differential, first and second halfshafts, first and second wheels, a first electric clutch selectively coupling the first wheel to the first halfshaft, and a second electric clutch selectively coupling the second wheel to the second halfshaft. A vehicle controller is programmed to: responsive to a request to activate the secondary axle and a first speed difference between the first and second wheels being less than a first threshold, engage the first and second clutches at a same time, and, in response to the request to activate the secondary axle and the first speed difference between the first and second wheels exceeding the first threshold, engage one of the clutches and then subsequently engage the other of the clutches once the one of the clutches is fully engaged.

Crawl operations for four-wheel steering vehicles are described herein. An example vehicle described herein includes four wheels, a front steering actuator to turn the front wheels, a rear steering actuator to turn the rear wheels, a front drive motor to drive the front wheels, and a rear drive motor to drive the rear wheels. The vehicle also includes an electronic control unit (ECU) to activate the front steering actuator to turn the front wheels in a first direction, activate the rear steering actuator to turn the rear wheels in a second direction opposite the first direction such that the front wheels and the rear wheels are turned in opposite directions, activate the front drive motor to drive the front wheels in a reverse direction, and activate the rear drive motor to drive the rear wheels in a forward direction while the front wheels are driven in the reverse direction.

An electrically driven vehicle includes at least one wheel driven by a motor, a vehicle body including a floor panel, a battery pack arranged on the lower side of the floor panel and configured to supply power to the motor, at least one wire harness extending in a front-rear direction of the electrically driven vehicle between the floor panel and the battery pack, and a harness cover extending in the front-rear direction of the electrically driven vehicle along the at least one wire harness and interposed between the at least one wire harness and the battery pack.

A vehicle includes an axle having left and right wheels. The vehicle further includes left and right torque-vector control devices each having an actuator with a released position, a fully actuated position, and a plurality of intermediate positions. A vehicle controller is programmed to, in response to the vehicle turning and one of the actuators being actuated, command different torques to the left and right wheels to produce torque vectoring between the wheels, wherein a difference between the torques commanded to the wheels increases as the actuator moves toward the fully actuated position and decreases as the actuator moves toward the fully released position.
