  • Patent number: 5969495
    Abstract: 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.

  • Patent number: 5959421
    Abstract: A motor direction control device id used for electromotive vehicles which has an electric motor adapted to cause the vehicles to move forwards and backwards. The motor direction control device includes a direction control level shiftable from a neutral position into forward or reverse position. Operatively connected to the direction lever is an elongated pliable strip which is slidable along a predefined moving way by the shifting operation of the direction control lever and carries a permanent magnet. First and second magnetolectric sensors are arranged in a spaced-apart relationship with each other along the moving way of the elongated strip, each of the magnetoelectric sensors capable of generating, when left deactivated, a position signal of first logic level and activatable by the permanent magnet to produce a position signal of second logic level as the direction control lever is shifted into the forward or reverse position.
