Embodiment 1

[0025] see figure 1 , the embodiment of the present invention provides a method for preventing the driver from stepping on the accelerator pedal by mistake, including:

[0026] 101: Obtain the current degree of motion of the accelerator pedal.

[0027] 102: Determine whether the current degree of motion of the accelerator pedal is greater than a preset threshold value of the degree of motion.

[0028] 103: If the current degree of movement of the accelerator pedal is greater than the preset degree of movement threshold, cut off the power of the vehicle.

[0029] Further, the method also includes:

[0030] Detect whether there are obstacles within the preset range of the car;

[0031] If there is an obstacle within the preset range of the car and the current degree of movement of the accelerator pedal is less than or equal to the preset degree of movement threshold, an alarm is activated.

[0032] Further, after detecting whether there is an obstacle within the preset range...

Embodiment 2

[0044] see figure 2 , the embodiment of the present invention provides a method for preventing the driver from stepping on the accelerator pedal by mistake, including:

[0045] 201: Obtain the current degree of movement of the accelerator pedal, and detect obstacles within the preset range of the car.

[0046] Specifically, the current degree of movement of the accelerator pedal in the embodiment of the present invention includes the current degree of opening and movement rate of the accelerator pedal.

[0047] Specifically, the accelerator pedal position sensor can be used to detect the opening degree and movement rate of the accelerator pedal in real time, and the accelerator pedal position sensor can be installed behind the accelerator pedal.

[0048] Specifically, the front detection radar can be used to detect obstacles within a preset range of the car, wherein the preset range mainly includes a certain distance in front of the car that may affect the driving safety of ...

Embodiment 3

[0063] see image 3 , the embodiment of the present invention provides a device for preventing the driver from stepping on the accelerator pedal by mistake, the device includes:

[0064] The degree of motion acquisition module 301 is configured to acquire the current degree of motion of the accelerator pedal.

[0065] Wherein, the degree of motion acquisition module 301 may specifically be an accelerator pedal position sensor and other devices capable of acquiring the current degree of motion of the accelerator pedal.

[0066] The judging module 302 is configured to judge whether the current degree of movement of the accelerator pedal acquired by the degree of exercise acquisition module 301 is greater than a preset degree of movement threshold.

[0067] Wherein, the judging module 302 may specifically be realized by an anti-misstepping accelerator pedal control unit.

[0068] The cutoff module 303 is configured to cut off the power of the vehicle when the judging result of ...

Abstract

The invention discloses a method and a device for preventing a driver from treading an accelerator pedal by accident, belonging to the technical field of automobiles. The method comprises the following steps of acquiring the current movement degree of the accelerator pedal, judging whether the current movement degree of the accelerator pedal is more than a preset movement degree threshold, and cutting off the power of the automobile if the current movement degree of the accelerator pedal is more than the preset movement degree threshold. The device comprises a movement degree acquisition module, a judgment module and a cutting-off module. The current movement degree of the accelerator pedal is acquired firstly, when the current movement degree of the accelerator pedal is more than the preset movement degree threshold, the power of the automobile is cut off, so that the driver can automatically cut off the power when the driver treads the accelerator pedal by accident and prevent the event of treading the accelerator pedal by accident, thereby improving the accuracy of preventing the driver from treading the accelerator pedal by accident.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and a device for preventing a driver from stepping on an accelerator pedal by mistake. Background technique [0002] With the development of automobile technology and the improvement of people's living standards, automobiles have gradually entered thousands of households, and the total number of automobiles has increased rapidly. The rapid increase of the total number of automobiles has brought severe traffic safety problems. Among them, traffic accidents caused by stepping on the accelerator pedal by mistake are not uncommon, and there are many accidents that cause heavy casualties. Therefore, how to prevent the driver from stepping on the accelerator pedal by mistake is a problem that is more concerned at present. [0003] The driver mistakenly stepped on the accelerator pedal mainly because the distance between the accelerator pedal and the brake pedal of the car...
