Method for controlling accelerators of electric or hybrid automobiles

Abstract

The invention relates to a method for controlling accelerators of electric or hybrid automobiles. By the aid of the method, shortcomings in the prior art can be overcome. The technical scheme includes that the method is applicable to the electric automobiles or the hybrid automobiles, and includes creating accelerator opening comparison tables and / or accelerator opening comparison formulas for the total weights of the automobiles; acquiring the current total weights of the automobiles; querying the accelerator opening comparison tables or the accelerator opening comparison formulas according to the current total weights of the automobiles to obtain current response corrected values; setting accelerator response according to the actual opening of the accelerators and the response corrected values. The method has the advantages that the accelerator opening comparison tables or the accelerator opening comparison formulas correspond to the current total weights of the automobiles, and accordingly the problem of change of accelerator response under different automobile load conditions can be solved; effects of setting the accelerator response of the automobiles according to current load information and keeping the accelerator response unchanged or similar under different load conditions can be realized; the problem of frictional force change conditions further can be solved by means of image processing, and integral running states can be beneficially complemented.

Problems solved by technology

However, in the existing technology, there is a unique correspondence between the throttle opening and the output power of the car engine. Therefore, once the load of the car changes and the stepping on the accelerator pedal is the same, the output power of the car engine is constant, but the final response of the car has changed. Although this has been the case for a long time There are always problems, but for the driver, the driving experience is still affected to a certain extent

[0003] Generally, the accelerator of a car controls the opening of the throttle to achieve the purpose of controlling the speed of the vehicle, but now electric vehicles or hybrid vehicles are beginning to emerge in the market as emerging vehicles, and the traditional method of controlling the throttle of automobiles is no longer applicable. Electric vehicles or hybrid vehicles Although the car throttle is called a throttle, it mainly controls the output power of the motor to achieve the purpose of controlling the output. Generally, it converts the output value by detecting the throttle opening, and then sends a drive command to make the motor output the corresponding power.
