Abstract
A control device may be configured for responding to failure for ensuring the stability of a vehicle by switching from a two-wheel-drive mode to a four-wheel-drive mode when detecting failure of the brake system in a two-wheel-drive mode.
Claims19
A control device for responding to failure of a brake system of a vehicle, the control device comprising:
- a first motor configured to selectively provide a driving torque to a main driving wheel of the vehicle;
- a second motor configured to selectively provide a driving torque to an auxiliary driving wheel of the vehicle;
- a disconnector provided at a driveshaft of the auxiliary driving wheel and configured to selectively switch a power transfer between the auxiliary driving wheel and the second motor;
- and
- a controller connected to the disconnector and configured to control the disconnector to connect the auxiliary driving wheel and the second motor upon detecting the failure of the brake system in the vehicle when the vehicle travels in a state in which the auxiliary driving wheel and the second motor are disconnected by the disconnector.

A control method for responding to failure of a brake system of a vehicle, the control method comprising:
- engaging, by a signal of a controller, a disconnector to connect an auxiliary driving wheel and a second motor upon detecting the failure of the brake system in the vehicle when the vehicle travels in a state in which the auxiliary driving wheel and the second motor are disconnected by the disconnector,
- wherein the vehicle includes:
- a main driving wheel, the auxiliary driving wheel, the controller, and the disconnector;
- the first motor configured to selectively provide a driving torque to the main driving wheel of the vehicle;
- the second motor configured to selectively provide a driving torque to the auxiliary driving wheel of the vehicle;
- and
- the disconnector provided at a driveshaft of the auxiliary driving wheel and configured to selectively switch a power transfer between the auxiliary driving wheel and the second motor according to the signal of the controller.
