Embodiment 1

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

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

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

[0028] 103: If the current motion degree of the accelerator pedal is greater than a preset motion degree 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 motion of the accelerator pedal is less than or equal to the preset motion threshold, an alarm will be activated.

[0032] Further, after detecting whether there is an obstacle within the preset range of the car, the method further includes:

[003...

Embodiment 2

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

[0045] 201 : Acquire the current motion of the accelerator pedal, and detect obstacles within a preset range of the car.

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

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

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

Embodiment 3

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

[0064] The exercise degree acquiring module 301 is used to acquire the current exercise degree of the accelerator pedal.

[0065] The exercise degree acquiring module 301 may specifically be a device that can acquire the current degree of exercise of the accelerator pedal, such as an accelerator pedal position sensor.

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

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

[0068] The cut-off module 303 is configured to cut off the power of the vehicle when the judgment result of the judgment module 302 is that the curre...

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 accidentally stepping on an accelerator pedal. 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 in the total number of vehicles has brought serious traffic safety problems. Among them, traffic accidents caused by mistakenly pressing the accelerator pedal are not uncommon, and there are many accidents that cause serious casualties. Therefore, how to prevent the driver from stepping on the accelerator pedal by mistake is a more concerned issue at present. [0003] The driver accidentally steps on the accelerator pedal mainly because the distance between the accelerator pedal and the brake pedal of the car is small, ...
