Abstract
A method of preventing wheel spin or wheel locking on an electric traction vehicle whose traction transmission includes servo controlling of one or more control parameters of the motor(s) of the traction transmission to an input reference value. The method is such that the control parameter(s) obtained at the output from the servo control are permanently limited by ideal values for the control parameter(s), which ideal values are such as to make it possible to obtain an input reference value for the speed of rotation of the motor(s) equal to the real travel speed of the vehicle, referred to as the reference speed, in such a manner as to stabilize the torque transmitted by the motor(s) in the event of wheel spin or wheel locking.
