According to the motor vehicle braking apparatus of the present invention, the engine throttle valve is closed when the driver treads the accelerator pedal to an extent exceeding a predetermined range, and the brakes are applied when the driver further treads the accelerator pedal to an extent equal to or greater than a predetermined limit. The braking force is adjusted according to the accelerator pedal treading. When the accelerator pedal treading is released to an extent equal to or greater than a predetermined limit, the application of the brakes is released. However, the engine throttle valve still remains closed. The normal function as the accelerator pedal is restored only after the accelerator pedal treading has been released to an extent near the level causing the accelerator pedal to be fully released. According to the apparatus of the present invention, when intended to apply the brakes in case of emergency, the driver is not required to change the pedal to be trodden, from the accelerator pedal to the brake pedal. This reduces the distance of vehicle travelling made while such pedal change is carried out. This also prevents an accident due to treading of an improper pedal. Further, there is reduced the likelihood that the driver erroneously applies the brakes, against his own will, in pedal operation. |

DETAILED DESCRIPTION The present invention provides a motor vehicle braking apparatus using the accelerator pedal.
In one arrangement of the invention, the accelerator pedal is adapted to serve as a normal accelerator pedal when the driver treads it with a treading force/displacement equal to or smaller than a predetermined value.
If the driver further treads the accelerator pedal with a treading force/displacement greater than the predetermined value, the engine throttle valve is closed.
If the accelerator pedal is further trodden to an extent exceeding a predetermined limit, the brakes are applied.
The braking force is adjusted according to the depth to which the accelerator pedal is trodden.
When the accelerator pedal is trodden to an extent exceeding the predetermined limit, the accelerator pedal serves as a brake pedal.
When the accelerator pedal treading is released to an extent exceeding a predetermined limit, the application of the brakes is released.
However, the engine throttle valve still remains closed.
After the accelerator pedal treading force has been released to an extent near the level where the pedal is fully relased, the accelerator pedal serves as a normal accelerator pedal.
As compared with a conventional system in which the function of either accelerator or brake is selected according to the position at which the treading force is applied to the pedal, the system of the present invention is simpler in operation since such function is selected according to the treading force or depth applied to the same position.
Accordingly, this reduces the likelihood that the driver erroneously treads the pedal in case of emergency.
According to the apparatus of the present invention, the same accelerator pedal may be used for applying the brakes not only in case of emergency, but also under normal conditions.
The apparatus may additionally include reaction force generating means arranged such that the accelerator pedal reaction force is suddenly increased when the accelerator pedal is trodden from the treading force/depth level at which the accelerator pedal serves as a normal accelerator pedal, to the treading force/depth level slightly smaller/shallower than the treading force/depth level at which the engine throttle valve is closed
