Abstract:
1. A vehicle skid control device of controlling at least one of an engine and a motor of 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; an engine vibration detection module that detects a vibration at a start of the engine; and a torque restriction prohibition module that prohibits said torque restriction module from restricting the driving torque of the drive wheels, in response to detection of the vibration at the start of the engine by said engine vibration detection module, 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.
