1. A vehicle controller comprising:
- an obstacle-determining portion that determines whether a vehicle is climbing up an obstacle; and
a driving torque reducing portion that performs a driving torque reduction control that reduces the driving torque when the obstacle-determining portion determines that the vehicle is climbing up the obstacle;
wherein;
the obstacle-determining portion determines that the vehicle is climbing up the obstacle when the driving torque exceeds a threshold value of the driving torque, in a condition where a vehicle speed is maintained to be substantially constant.

Abstract
A vehicle controller includes an obstacle-determining portion and a driving torque reducing portion. The obstacle-determining portion determines whether the vehicle is climbing up an obstacle, more specifically, whether the vehicle starts climbing up the obstacle. Then, the driving torque reducing portion performs a driving torque reduction control when it is determined that the vehicle is climbing up onto the obstacle.

10. A vehicle controller comprising:
-
an obstacle-determining portion that determines whether a vehicle is climbing up an obstacle; and a driving torque reducing portion that performs a driving torque reduction control that reduces the driving torque when the obstacle-determining portion determines that the vehicle is climbing up the obstacle; wherein; the driving torque reducing portion estimates a height of an obstacle based on the driving torque applied when it is determined that the vehicle is climbing up the obstacle, and estimates a distance that the vehicle needs to move in order to get on top of the obstacle based on the estimated height, and starts the driving torque reduction control when the vehicle has moved the estimated distance. - View Dependent Claims (12)

13. A method for controlling a driving torque of a vehicle, comprising the steps of:
-
determining whether the vehicle is climbing up an obstacle based on whether the vehicle speed increases from substantially 0, and the driving torque exceeds a threshold value of the driving torque; and performing a driving torque reduction control that reduces the driving torque when the vehicle speed increases from substantially 0, and the driving torque exceeds a threshold value of the driving torque. - View Dependent Claims (14)

15. A vehicle controller, comprising:
-
obstacle-determining means for determining whether a vehicle is climbing up an obstacle; and driving torque reducing means for performing a driving torque reduction control that reduces the driving torque when the obstacle-determining means determines that the vehicle is climbing up the obstacle; wherein the obstacle-determining means determines that the vehicle is climbing up the obstacle when a vehicle speed increases from substantially 0, and the driving torque exceeds a threshold value of the driving torque.
