IPC: B60W10/04
Filed: 2018-05-23
Abstract: To provide a stack escaping device that is capable of escaping from a stack state by automatically switching the direction of driving force without relying on manual operation of a driver.SOLUTION: If a moving speed-position detection unit 2 detects a speed=0 when a vehicle advances forward, for example, a driving force inversion commanding unit 3 determines that the vehicle has become unable to climb at the middle of a slope of a recess, that is, a top dead center has been reached, and outputs an inversion command for longitudinal driving force to a driving-braking force control unit 4. Thus, tires descend on the slope by moving in the opposite direction and then climb the slope to reach the opposite top dead center. Upon determining that the opposite top dead center has been reached, the driving force inversion commanding unit 3 outputs an inversion command to the driving-braking force control unit 4. By repeating such operations, the tires finally completely climb the slope to escape from a stack.SELECTED DRAWING: Figure 1
