  • Patent number: 10824184
    Abstract: I was training my teen student driver on the road when I came up with this brilliant yet innovative idea. It is very hard to control the vehicle by just merely yelling “BRAKE” to the student driver. It is unfair to other motorists the risk they are unknowingly taking without an absolute control of the vehicle of a professional driver who is just sitting on the passenger side. In view of this unsafe training condition, I designed and fabricated a Famor Extension Brake. It is a mechanical device that is easily installed on any motor vehicle without modifications. Using this device, the passenger can independently apply the brake to the vehicle when the driver fails to do so. These can be a student, old or destructed drivers.

    Abstract: A vehicle hand control apparatus for controlling the throttle and brake pedals of a motor vehicle. A support shaft pivotally supports a transverse control arm tube which holds a control shaft for rotation coaxially within the control arm tube. A handle extends from one end of the control arm tube for actuating the brake pedal and also for separate limited pivotal movement about a handle pivot axis orthogonal to the rotational axis of the control arm tube for actuating the accelerator pedal. Pivotal movement of the handle about the handle pivot axis causes separate interacting transfer rods dependently extending from the handle and the control shaft, respectively, to effect rotation of the control shaft and accelerator pedal movement.

  • Patent number: 6407526
    Abstract: Some automobiles have mechanisms for adjusting the height of accelerator and brake pedals, and any clutch pedal, so that drivers large and small can adjust the pedals to the best height. All pedals are adjusted by a single reversible electric motor having a shaft connected directly or by a flexible shaft to the adjusting mechanisms. If any fault develops in any mechanism, the pedals may not be adjusted to the same height, which is hazardous to the driver. A safety switching system detects any serious misalignment of the pedals and de-energizes the motor. The system comprises separate switches which are operable by adjustment of the pedals, and are electrically connected in series with the power supply circuit for the motor. When the pedals are aligned, the bridging contactors of the switches are aligned and are effective to maintain the electrical continuity of the motor circuit. Each contactor has three contact sliders which successively engage staggered tabs on contact strips for the respective pedals.

  • Patent number: 6263753
    Abstract: A control device for vehicle steering, braking and accelerator, including but not limited to motor vehicles for use by handicapped drivers, especially those handicapped in the lower limbs, is provided. The control device relates to a system utilizing the steering wheel to accomplish both steering and braking and an accelerator lever device to control the accelerator operations of the vehicle. Specifically, the present invention relates to a system wherein the steering is accomplished in a normal manner by the driver, but the driver need only push forward on the steering wheel to accomplish the braking operations or move a lever device to control the speed of the vehicle. The control device for vehicle steering, braking and accelerator may be employed in any vehicle, including but not limited to motor vehicles, with a mechanical or an automatic gear box.

  • Publication number: 20010006284
    Abstract: A steering and control system is disclosed which includes a steering wheel that not only allows for the operator to accomplish the steering of a vehicle, but also allows the operator to merely exert a force on the steering to control the braking mechanism of a vehicle. The steering wheel, acting as a unitary device for controlling two of the principal operations of a vehicle, provides the operator with improved handling capabilities and does so without the operator needing to use his/her feet which makes the control system of the vehicle particularly suited for handicapped individuals.

  • Patent number: 6041673
    Abstract: A dual function throttle control system is disclosed for earthmoving machines. The throttle control system includes a hand lever that is electrically connected to a proportional directional hydraulic valve. Rotation of the hand lever controls actuation of an engine speed actuator and thus the speed of the engine. A foot pedal is connected through a three position spring-centered hydraulic valve to the engine speed actuator. The direction of flow of hydraulic fluid through the three position spring-centered hydraulic valve is controlled by the position of the hand lever. When the hand lever is set at the lowest speed setting, rotation of the foot pedal in a first direction increases the engine speed. When the control lever is set at the highest speed setting, rotation of the foot pedal in the first direction decreases the speed of the engine. Thus, the foot pedal operates both as a decelerator or an accelerator depending on the position of the hand lever.

  • Patent number: 6006880
    Abstract: A power take-off release mechanism for automatically disengaging a power take-off unit and accessory equipment powered thereby is disclosed. The power take-off release mechanism interconnects a clutch foot pedal mechanism of a vehicle having a manual transmission to a throw out arm on the power take-off unit. The power take-off unit includes a mechanical cable linkage which functions to engage the power take-off unit in a conventional manner. Thereafter, whenever the manual clutch foot pedal is depressed to put the vehicle in gear under normal driving conditions, the power take-of mechanism of the present invention is automatically actuated to disengage the power take-off unit thereby preventing the same from being operated at higher engine revolutions under normal driving conditions. In one embodiment, the power take-off release mechanism includes a mechanical cable linkage that interconnects the clutch foot pedal with the mechanical throw out arm on the power take off unit.

    Abstract: An operating element arrangement controls the longitudinal and transverse movements of a motor vehicle, with a foot-actuatable regulating part for controlling braking operations. The operating element arrangement contains a regulating part for controlling the transverse movement of the vehicle, which is arranged so as to be manually actuatable in the transverse direction of the vehicle and into which a finger-actuatable regulating part for controlling acceleration operations is integrated. A steering wheel and accelerator pedal can be eliminated, and a distinct spatial and operationally functional separation of the activation of braking operations, on one hand, and of acceleration operations, on the other hand are provided.

  • Patent number: 5967252
    Abstract: A push-button actuated system for an ATV transmission such as those used on a Honda 300 where a DC motor is connected to a cable linkage, which in turn is connected to the gear change pedal now used to upshift and downshift gears of a semi-automatic transmission. The cable linkage is arranged so that a clockwise rotation of the DC motor causes a cable to pull upwardly on the gear change pedal. A counterclockwise rotation of the DC motor causes the cable linkage to pull downwardly on the pedal. Variations do away with the pedal and cause rotation of the operative transmission shaft in the same manner as the pedal.

  • Patent number: 5941361
    Abstract: The present invention for a construction machine includes a control knob which is connected to a brake pedal and located remotely therefrom within an operator's compartment. The control knob depresses the brake pedal a predetermined amount to achieve neutralization of the hydrostatic transmission. Neutralization of the hydrostatic transmission is presently available by continuous direct application of the brake pedal. The control knob is adjustable within a plurality of positions to set a selected ground speed which, in turn, allows for increased hydraulic power availability to an implement achieved through the hydrostatic transmission neutralization. An electrical circuit is provided that includes a limit switch which overrides the actuation of a brake light signal unless an operator directly applies pressure to the brake pedal. Therefore, the brake light signal is not actuated during the remote setting of the control knob.
