Method for judging mistaken stepping of accelerator, and method for preventing mistaken stepping of accelerator through method

Abstract

The invention provides brand-new methods for judging and preventing mistaken stepping of an accelerator. Double judgment is adopted when whether the accelerator is mistakenly stepped or not is judged,misjudgment is avoided, firstly, the real-time accelerator opening degree is compared with a set opening degree parameter, when the real-time accelerator opening degree exceeds the set opening degreeparameter, the stepping speed of an accelerator pedal after the real-time accelerator opening degree exceeds the set opening degree parameter is judged, the stepping speed of the accelerator pedal atthe moment is compared with a set speed parameter, when real-time values in double judgment both exceed the set parameters, it is identified that the accelerator is mistakenly stepped, and the reasonable and precise effects are achieved; meanwhile, the opening degree parameter and the speed parameter are set in a default mode and in a self-learning mode; and a vehicle can enter into the self-learning mode after being powered on, vehicle ignition is not needed, the entering mode is that the self-learning mode can be entered when the set number of times of mistaken stepping is reached within the set time, even if the vehicle enters into a self-learning state after being ignited, the vehicle is in an idling state at the moment, and thus the danger does not occur.

Description

[0001] Technical field: [0002] The invention relates to the technical field of automobile throttle control, and more specifically relates to a method for judging a wrong step on the accelerator and a method for preventing the wrong step on the accelerator using the method. [0003] Background technique: [0004] In recent years, with the development of science and technology, there are more and more vehicles, but there are often drivers who mistake the accelerator for the brake, especially for novice drivers. Vehicles go out, causing major accidents, so how to solve this problem is very urgent. Many experts and scholars have also invented a lot of methods and principles for identifying misstepping on the accelerator. Generally, there are two methods. One is to compare and judge the speed of depressing the accelerator pedal with the user data in the feature library, and the other is to judge it according to the opening of the accelerator pedal. Comparing and judging with the ...

Problems solved by technology

In this method, it is necessary to judge whether the speed of the vehicle exceeds a certain threshold before judging whether to step on it by mistake. However, in the results of our analysis, stepping by mistake often occurs when the speed is very low, especially when the driver is parking. Unreasonable; of course, what is more fatal is that if the driver mistakenly uses the accelerator as the brake or the accelerator is stuck by the floor pad before the vehicle starts, if the engine speed will become very high immediately after ignition at this time, if the gear is at this time If the vehicle is in the driving gear, it will inevitably cause the vehicle to go out and cause a car accident. According to the above patent method, this situation cannot be judged. Therefore, it is not possible to add the speed of the vehicle to the judging condition for judging that the accelerator is stepped on by mistake.

Furthermore, his invention clearly stated that when the vehicle is moving forward, it is necessary to judge that the accelerator pedal of the vehicle is stepped on and released before proceeding to the next step of judgment. As mentioned above, misstepping is especially likely to occur when parking is in place. At this time, most The driver does not step on the accelerator pedal at all, but controls the vehicle with idle speed, that is to say, the accelerator pedal is always at the initial position at this time, but at this time, the accelerator is stepped on by mistake, which is also undetectable according to the steps of the above invention
