Description
Technical Field
The invention relates to a fault-tolerant method for an automobile accelerator, and belongs to the industry of automobile industry.
Background
With the rapid development of the automobile industry, the amount of vehicle retention has increased year by year, and various measures and devices related to vehicle safety have been continuously researched and improved. At present, no matter a conventional fuel vehicle, an electric vehicle or a new energy vehicle is provided with an intelligent control device and an auxiliary brake device such as a brake auxiliary system, a brake priority system, a voice intervention system and the like, but no solution for enabling an accelerator to be invalid when the accelerator is mistakenly stepped on a brake in an emergency situation exists.
Disclosure of Invention
The invention aims to solve the technical problem that when the accelerator is mistakenly stepped on as a brake in an emergency, the accelerator is disabled, and the risk caused by mistakenly stepping on the accelerator as the brake is reduced or avoided. The invention adopts the technical scheme that a fault-tolerant method of an automobile accelerator is provided, which comprises an accelerator pedal 1 and an accelerator control unit 2, wherein the accelerator refers to the condition that the accelerator pedal 1 and the accelerator control unit 2 are combined to control the power (thrust) of an engine, and the fault-tolerant method is characterized in that: the control process of the accelerator comprises A, B, C three position travel points of the accelerator pedal 1, wherein point A is the free state position of the accelerator pedal 1, the accelerator is 0, the travel of the section AB is the travel of the accelerator function, point B is the dividing point of the accelerator, the travel of the section BC is 0, and point C is the maximum position (limit position) of the accelerator pedal 1. The AB segment of the travel of the accelerator pedal 1 can be further subdivided into 4 schemes: 1) the accelerator has one section from 0 to the maximum, 2) the accelerator has two sections from 0 to the maximum to 0, 3) the accelerator has two sections from 0 to the maximum, and 4) the accelerator has three sections from 0 to the maximum to 0. The position of the B point of the accelerator pedal 1 can be added with certain resistance, and the resistance can be a single B point or the whole BC section. After the accelerator pedal 1 passes the point B, the accelerator is 0, and the accelerator returns to the point B for recovery. For the sake of safety, it may be set that the accelerator is 0 after the accelerator pedal 1 crosses the point B, and the accelerator function of the accelerator pedal 1 fails, and even if the accelerator pedal 1 returns to the AB-stage accelerator or 0, the accelerator pedal 1 resumes the accelerator function again only after the accelerator pedal 1 returns to the point a (natural state).
Drawings
FIG. 1 is a schematic of the present invention. In the figure: 1-accelerator pedal and 2-accelerator control unit.
Detailed Description
The invention will be further described with reference to fig. 1.
In the invention, the accelerator means that an accelerator pedal 1 and an accelerator control unit 2 are combined to control the power (thrust) of an engine, in order to realize accelerator fault tolerance, A, B, C three position travel points are arranged on the accelerator pedal 1, when the accelerator pedal 1 is positioned at the position of A, namely the accelerator pedal 1 is positioned in a natural state (no external force trampling and no displacement), the accelerator is 0, and when the accelerator pedal 1 moves from the position A to the position B, the accelerator control unit 2 can realize 4 control schemes according to the feedback of the position of the accelerator pedal 1: 1.) the accelerator is gradually increased from 0 in the process that the accelerator pedal 1 is from the position A to the position B, and the accelerator reaches the maximum value when approaching the position of the point B; 2.) the accelerator pedal 1 gradually increases from 0 to the maximum value and then gradually decreases from the maximum value to 0 again in the process from the A position to the B position; 3.) the accelerator pedal 1 gradually increases from 0 to a maximum value and then continues to be the maximum value in the process from the A position to the B position; 4.) the accelerator pedal 1 gradually increases from 0 to the maximum value from the a position to the B position, and the maximum value gradually decreases from the maximum value to 0 after a certain travel. When the accelerator pedal 1 is stepped to the position of the B point, the accelerator is 0, and the accelerator of the accelerator pedal 1 is 0 in the whole travel section from B to C. When the accelerator pedal 1 returns after passing through the B point, 2 control schemes can be set: 1.) the accelerator pedal 1 returns to the travel position of the section AB after crossing the position of the section B, and the accelerator is recovered in time, namely the size of the accelerator is only related to the position of the accelerator pedal 1 and is not related to whether the accelerator pedal crosses the position of the section B or not; 2.) the accelerator is 0 after the accelerator pedal 1 crosses the position B, and the accelerator function is invalid, even if the accelerator pedal 1 returns to the position AB, but does not return to the position A, the accelerator is always 0, and only if the accelerator pedal 1 returns to the position A, the accelerator control function of the accelerator pedal 1 is recovered.
The accelerator pedal 1 realizes position control and feeds back position information to the accelerator control unit 2, and the accelerator control unit 2 realizes the control of the accelerator by combining the feedback information and a preset control scheme.
