Vehicle control method
First Claim
1. A vehicle equipped with a power output device that is capable of outputting a driving force to a drive shaft linked with left and right wheels, said vehicle comprising:
- a mechanical braking device that is capable of outputting a mechanical braking force to each of the left and right wheels;
a slip detection module that detects a slip on each of the left and right wheels caused by wheelspin; and
a controller that, in response to detection of a slip caused by spin of one of the left and right wheels by said slip detection module, drives and controls said power output device to restrict the driving force output to the drive shaft, while actuating and controlling said mechanical braking device to output a mechanical braking force to the spinning one of the left and right wheels.

Abstract
In response to detection of a slip occurring on left and right front wheels (62a, 62b) caused by spin of one of the left and right front wheels (62a, 62b), the control technique of the invention restricts a torque output from a motor (22) to a drive shaft (28), while activating a hydraulic brake (54a) or (54b) corresponding to the spinning wheel to output a brake torque, so as to distribute the output torque of the motor (22) practically equally into the left and right front wheels (62a, 62b). This arrangement desirably improves the starting performance and the accelerating performance of a vehicle with the left and right front wheels (62a, 62b) running on the road surface of different frictional coefficients.
