<p>PURPOSE:To achieve compatibility of starting acceleration in linear running with driving stability in turning, in controlling a torque regulating means so as to make a slip ratio identical with an aimed slip ratio, by determining the aimed slip ratio based on a steering angle by a steering angle detecting means and steering angular velocity. CONSTITUTION:In driving a car, at a CPU 21, an output signal of each wheel speed sensor 18a, 18b, 19a, 19b is input, so as to define car velocity V for which an average wheel speed of right and left front wheels is determined. The larger wheel velocity of right and left rear wheels is chosen to define it velocity of driving wheel VW, and a slip ratio S is operated from an expression S=(VW-V)/VW. A basic aimed slip ratio is determined from a handle steering angle by a steering angle sensor 13, and is corrected by a correction value based on steering angular velocity so as to decide a final aimed slip ratio Sa. An aimed throttle opening is operated to make the slip ratio S closer to the final aimed slip ratio Sa, and a throttle valve 4 is thus controlled open or close by a stepping motor 5.</p> |
