Embodiment 1

[0014] Embodiment 1 This example is suitable for the transformation of the electronic accelerator vehicle that has been delivered. A block diagram such as figure 1 , the protection module circuit and the car circuit share the same ground, the function (program) block diagram of the protection module is as follows figure 2 , connect the signal of high level in the brake switch to the corresponding input terminal of the protection module when the brake pedal is pressed, cut off the two output signal lines of the accelerator pedal position sensor, and connect the line on the pedal side to the input of the corresponding protection module terminal, the wire on the side of the engine control unit is connected to the corresponding output terminal of the protection module.

Embodiment 2

[0015] Embodiment 2 This embodiment is applicable to the improvement of the automobile before delivery or design by the manufacturer. A block diagram such as image 3 , by modifying the engine control unit program, the figure 2 The function program is integrated into the engine control unit program, so that the accidental accelerator pedal protection can be realized at zero cost.

Embodiment 3

[0016] Embodiment 3 This example is suitable for a car with a cable-pull throttle. Since there is no accelerator pedal position sensor in the car with the wire accelerator, a throttle position sensor is used instead. The information that the accelerator is depressed is obtained by detecting the change of the value of the throttle position sensor, and the identification is integrated into the engine control unit similar to the second example. After the control program recognizes that the accelerator is accidentally stepped on, the engine control unit closes the fuel injector, thus avoiding the sudden acceleration of the car.

Abstract

The invention discloses a novel identification method of mistaken automobile accelerator stepping and a protection scheme based on the method. According to the analysis of mistaken accelerator stepping cases and mistaken stepping occurrence process, at the moment before mistaken stepping, a driver slightly steps on the brake and slowly drives the automobile (such as backing up or driving into and driving out of a parking place, and the like), after being suddenly stimulated, the driver quickly loosens the brake and heavily steps on the accelerator in panic, the automobile is accelerated rapidly, and serious consequences are caused. The time past from driver loosening the brake to stepping on the accelerator is adopted as the judgment reference, and during normal operation, the time required from unhurriedly loosening the brake to stepping on the accelerator and the time required from loosening the brake to stepping on the accelerator in a hurry has obvious difference, and through utilizing the difference, the identification method can easily and reliably identify whether the driver normally accelerates the automobile or mistakenly steps on the accelerator. When the situation of mistaken accelerator stepping is identified, an engine is locked at the idle speed, the rapid acceleration of the automobile is avoided, the driver can possibly step on the brake for remedy, and the serious consequences are avoided.

Description

technical field [0001] The invention relates to an identification method for accidentally stepping on an accelerator of an automobile and a protection device based on the method, belonging to the technical field of automobile safety. Background technique [0002] Cases of accidents caused by mistakenly stepping on the accelerator are often seen in various media. With the continuous increase in the number of private cars, there are more and more opportunities for non-professional drivers to drive, and similar accidents will also increase. The resulting personal and property damage will also increase, so it is very necessary to develop active safety protection technology for automobiles. At present, there are many disclosed protection technologies to prevent accidental stepping on the accelerator and after stepping on the accelerator by mistake, but each has some defects, either too complicated, high cost, not practical; or low reliability, and there are additional risks.
