Abstract
A first threshold is determined, with reference to an absolute acceleration that is determined in accordance with a vehicle usage condition, to detect an acceleration change generated in acceleration of a self-axle speed that is a maximum speed (a minimum speed in a decelerating operation) of revolving speeds of plural motors that drive plural driving wheel axles. When the acceleration exceeds the first threshold, a system for generating a target torque command value reduced in accordance with the acceleration deviation is separated by setting an output of a comparator circuit to level '0', and a first-order delay circuit outputs the target torque command value subjected to a reduction process during a processing period designated by an output of a delay time generating circuit.
