Vehicle stability control system

A vehicle stability control system of a vehicle having a vehicle body, front and rear wheel suspensions that support the vehicle body, an accelerator and power regulating means for regulating engine power, thereby producing a desired vehicle drive force, the vehicle stability control system comprising:

• body vibration detection means for detecting a pitching vibration of the vehicle body which occurs during running of the vehicle based on a vehicle body input torque from a quantity sensor;
• and
• correction means configured to determine a correction physical quantity corresponding to the pitching vibration detected by the body vibration detection means, and control the power regulating means based at least on the correction physical quantity,
• wherein the correction means determines a drive force proportion between the engine and the power regulating means based on operation of the accelerator, and corrects a physical quantity corresponding to the drive force proportion based on the correction physical quantity,
• wherein the power regulating means is a set of a starter and an alternator, and
• when the correction physical quantity is negative, the correction means outputs the correction physical quantity as an instruction signal for driving the alternator, and
• when the correction physical quantity is positive, the correction means outputs the correction physical quantity as an instruction signal for driving the starter.
