Patent ID: 7377349

Claim:
A vehicle skid control device of controlling a power system that outputs power to a drive shaft linked to drive wheels of a vehicle, said vehicle skid control device comprising: an angular acceleration measurement module that measures an angular acceleration of the drive shaft; a skid detection module that detects occurrence of a skid of the drive wheels according to the measured angular acceleration; a torque restriction module that, in response to detection of the occurrence of a skid by said skid detection module, restricts a driving torque of the drive wheels to reduce the skid; a torque variation detection module that determines whether a variation in torque command value of the drive wheels caused by a driver's accelerator operation is within a preset range; and a torque restriction prohibition module that prohibits said torque restriction module from restricting the driving torque of the drive wheels, when said torque variation detection module determines that the variation in torque command value is out of the preset range wherein said skid detection module detects the occurrence of a skid when the angular acceleration measured by said angular acceleration measurement module increases over a preset threshold value wherein said torque restriction prohibition module does not prohibit said torque restriction module from restricting the driving torque of the drive wheels, when the angular acceleration measured by said angular acceleration measurement module exceeds a non-skid upper limit, which is set to be larger than the preset threshold value.
