ABSTRACT:
A control device and corresponding method for controlling a traction function or a braking function of a vehicle, including a moving control lever which can be set in a first position 0 in which neither the traction function nor the braking function are activated, and an unstable position 0i in which the vehicle coasts by reducing electrical traction force and electrical braking force to zero. The control lever can be moved from the first position 0 over a first zone 0+ in which the electrical traction function is activated, either by increasing the electrical traction force, or by decreasing the electrical braking force. The control lever further can be moved from the first position 0 over a second zone 0- in which the electrical braking function is activated, either by decreasing the electrical traction force, or by increasing the electrical braking force. Additionally, the control lever can be moved from a--end of the second zone 0- over a third zone -F in which a pneumatic braking function of the vehicle is activated, and can be set in a second position EM, following the third zone -F, in which both the electrical braking function and the pneumatic braking function are activated simultaneously.
