Title:
車両駆動力装置
Document Type and Number:
Japanese Patent JP4371270
Kind Code:
B2
Abstract:
The present invention relates to a vehicle driving system, wherein a differentiator (141, 142, 143) calculates the acceleration of the rear wheels. An acceleration threshold calculation means (144) enable the skid-detection acceleration threshold to be adjusted corresponding to the conditions of the vehicle. An acceleration skid-detection means (145) make a comparison between the acceleration of the wheels obtained by the differentiator (141, 142, 143) and the skid-detection acceleration threshold adjusted by the acceleration threshold calculation means (144), and determine whether or not a skid of the wheels has occurred, based upon the comparison result. Such an arrangement provides a vehicle driving force system having a function of detecting a skid even in a case that a skid of the wheels has occurred at a low acceleration of the vehicle.
