An accelerator device is used for electromotive vehicles which has an electric motor adapted to cause the vehicles to move forwards and backwards. The accelerator device includes an accelerator pedal depressible to swing between a rest position and a most depressed position. Operatively connected to the pedal is an elongated pliable strip which is slidable along a predefined moving way and carries a permanent magnet. A plurality of magnetoelectric sensors are arranged along the moving way of the strip with a substantially equal spacing from one another, each of the sensors capable of generating, when left deactivated, a pedal position signal of first logic level and activatable by the magnetic flux of the permanent magnet to produce a pedal position signal of second logic level as the permanent magnet moves over and above the respective one of the sensors. Responsive to the pedal position signals, a microprocessor is adapted to control the torque and speed of the electric motor by way of regulating the amount of electric current to be supplied to the electric motor. The magnetoelectric sensors include a Hall generator that normally gives an output voltage signal of logic level one but produces an output voltage signal of logic level zero when aligned with the permanent magnet.
