<p><P>PROBLEM TO BE SOLVED: To attain proper traveling control even when a throttle controller receives two different throttle control signals at the same time. <P>SOLUTION: This traveling controller is constituted so that an engine control unit 20 and a throttle actuator 2a, a rotation driving force distributing device 10 for performing transmission torque distribution control to front wheels and rear wheels, four-wheel driving control unit 30 and a traveling stabilization control unit 40 are contained in a four-wheel drive car 1. The four-wheel driving control unit 30 stops four-wheel driving control when any failure related with the function defect of the four-wheel drive traveling control is generated, and controls the throttle control unit 20 to decrease a throttle aperture. When different throttle control signals are simultaneously inputted from the four-wheel driving control unit 30 and the traveling stabilization control unit 40 to the engine control unit 20, the engine control unit controls throttle aperture based on the control signal whose throttle aperture is smaller. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
