Abstract

A vehicle system includes an engine driving a vehicle, a front wheel and a rear wheel, a suspension device with an attachment portion to a vehicle body which is located at a higher level than a center axis of the rear wheel, an electromagnetic coupling to distribute a torque of the engine to the front wheel and the rear wheel, a steering wheel to be operated by a driver, a steering angle sensor to detect a steering angle corresponding to operation of the steering wheel, and a controller to control the engine and the electromagnetic coupling. The controller is configured to control the electromagnetic coupling such that the torque distributed to the rear wheel is decreased in accordance with a returning operation of the steering wheel which is detected by the steering angle sensor.

Dependent claims

A vehicle system, comprising:

a power source configured to drive a vehicle;
a front wheel and a rear wheel;
a torque distributing mechanism configured to distribute a torque of the power source to the front wheel and the rear wheel;
a steering wheel to be operated by a driver;
a brake provided at each of the front wheel and the rear wheel;
a steering angle sensor configured to detect a steering angle which corresponds to operation of the steering wheel;
and
a controller configured to control the power source and the torque distributing mechanism, such that the torque distributed to the rear wheel is decreased in accordance with a returning operation of the steering wheel which is detected by the steering angle sensor;
wherein the controller is configured to control the brake which is provided at a turning outer wheel such that a yaw moment which has an opposite direction to a yaw rate generated at the vehicle is applied to the vehicle when the returning operation of the steering wheel is conducted.
