The following description relates to a fault tolerant apparatus for an independent controlled steering in a four wheel system, particularly a fault tolerant apparatus for an independent controlled steering in a four wheel system which can stabilizes a vehicle body through actively adjusting a steering angle of a vehicle and a velocity of a vehicle according to a breakdown environment and a vehicle driving road environment. Further, a fault tolerant apparatus for an independent controlled steering in a four wheel system that may assist a safe driving environment by adjusting a turning function adoptively to a surrounding road environment.

Fault tolerant apparatus for an independent controlled steering in a four wheel system

The present description relates to an apparatus and method for fault tolerant trajectory generation of a left-right independent active front steering vehicle that calculates a driving optimal route of a vehicle considering turning radius increase of a vehicle that is generated due to fault management because of a fault generated on any one of steering device between a left or right steering device of a vehicle and turning possible level of a surrounding road.

Apparatus and method for fault tolerant trajectory generation a left-right independent active front steering vehicle

The present disclosure relates to fault management apparatus and method for an independently controlled steering system in a four wheel drive system. The apparatus includes: a steering system unit that is disposed at four wheels of a vehicle, controls steering of the wheels, and collects and transmits the state information of the wheels; and a control unit that controls the steering system unit in accordance with the state information transmitted from the steering system unit. According to the present disclosure, when there is a fault in one or more wheels of a four wheel drive vehicle, it is possible to stabilize the vehicle body by actively adjusting the steering angles of the wheels that normally work and the speed of the vehicle in accordance with the fault environment.
