Abstract

A vehicle includes drive wheels and a motor connected thereto with torque controlling apparatus and a slip indicating device. Excessive slip indications per unit time are monitored and cause reduction in the torque applied by the motor until the slipping is overcome at which time torque is gradually increased.
