Zusammenfassung: | PURPOSE:To aim at improvement in accelerability by altering a throttle closing speed at the time of throttle control starting according to degree of acceleration in the racing of each driving wheel, in a traction controlling method which restrains the racing of driving wheels by means of throttle control. CONSTITUTION:At the initial stage of throttle control, mean acceleration V'G at a while till al reference speed Vr calculated out of wheel speeds VdL, VdR of driving wheels exceeds a threshold speed Vs from speed equal to a pseudo body speed Vv is calculated. According to the degree of this mean acceleration V'G, throttle closing speed in the first throttle closing control is altered. Consequently, such throttle control that is suitable for road conditions can be done, thus improvements in starting and accelerability can be promoted. |
