Embodiment Construction

[0048] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0049] The present invention aims at the problem that drivers often mistakenly step on the accelerator as the brake during the driving process, causing the car to lose control, and even lead to serious traffic accidents. The brakes are used to judge the accelerator pedal by mistake, so as to ensure that the vehicle speed during driving will not cause the car to accelerate out of control due to the driver's mistaken accelerator pedal behavior, thereby reducing the loss of the driver and the vehicle.

[0050] like figure 1 As shown, the embodiment of the present invention provides a method for recognition and protection of accelerator when braking, including:

[0051] Step 11, after the vehicle speed is greater than the first threshold, acquire the motion...

Abstract

The invention provides a method, a device, a controller and an automobile for identifying and protecting the accelerator pedal as a brake. The method includes: after the speed of the vehicle is greater than the first threshold, acquiring the motion signal and the accelerator signal of the vehicle in real time; analyzing the motion direction of the vehicle according to the motion signal, and determining the running state of the car, the running state includes: forward driving and reverse; Currently driving in the forward direction, determine whether an event that the accelerator pedal has been stepped on and released has occurred. If an event has occurred, when the accelerator signal is greater than the second threshold and the change of the accelerator signal within the preset time period is greater than the third threshold , to determine that the accelerator has been stepped on by mistake; if the car is currently in reverse, when the accelerator signal is greater than the second threshold and the change in the accelerator signal within the preset time period is greater than the third threshold, it is determined that the accelerator has been stepped on by mistake; when it is determined that the accelerator has been stepped on by mistake After that, the preset signal is output to the car engine controller to make the car run safely at low speed. The scheme of the invention ensures the safety of driving.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method, a device, a controller and an automobile for identifying and protecting an accelerator as a brake. Background technique [0002] Now with the popularization of cars and the continuous reduction of car prices, more and more families buy cars as means of transportation. [0003] However, with the increase of car ownership, many problems have also appeared, especially in the process of driving, the driver regards the gas pedal as a brake for various reasons, causing the car to lose control after stepping on it by mistake, and even lead to serious traffic accidents. Contents of the invention [0004] The object of the present invention is to provide a method, device, controller and automobile for identifying and protecting the accelerator as a brake, so as to realize the judgment that the driver of the automobile uses the accelerator as a brake and thus step on the ac...
