Abstract:

A tactile feedback device such as a bumper or prod located to give the operator of a wheeled vehicle tactile feedback when the leg of the operator is in operable position to depress the brake pedal. Preferably, the feedback device is locatably adjustably fixed to the body of the vehicle in a location causing contact when the leg of the operator is in an ergonomically comfortable and ordinary position for depressing the brake. Illustratively, the device may depend from the steering column of a passenger automobile. In an alternative embodiment, the feedback device is readily removable from the vehicle. In a further alternative embodiment, contact characteristics may be adjusted to be, at one end of a range of adjustment a soft contact, at the other end of a range of adjustment a solid, unyielding contact, or any intermediate between the two ends of the range of adjustment.
