Speed setting control method during acceleration of electric vehicle

Abstract

The invention discloses a speed setting control method during acceleration of an electric vehicle. The method is characterized by comprising the following steps: acquiring the highest speed limit of an electric vehicle, and acquiring a target speed from a rotating handle of the electric vehicle according to a first acceleration and a second acceleration set by the highest speed limit of the electric vehicle, setting a switching rotating speed for switching the first acceleration and the second acceleration according to the target speed; calculating the acceleration of a given speed and the given speed according to the first acceleration, and recording the working duration of the first acceleration; determining whether the real-time rotating speed is larger than the switching rotating speedor not, if so, recording the total working duration of the first acceleration, and calculating the acceleration of the given speed and the given speed through the second acceleration; judging whetherthe given speed is equal to the target speed or not, and if so, ending the acceleration process; by means of the method, smooth starting and powerful acceleration of the electric vehicle can be achieved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle control, in particular to a control method for a given speed when an electric vehicle accelerates. Background technique [0002] Electric vehicles are an important daily means of transportation, meeting people's needs for short-distance travel. It has the advantages of environmental friendliness and convenient use. [0003] Most electric vehicle manufacturers on the market have neglected to improve the driving experience of electric vehicles. Many electric vehicles accelerate too fast at the start, giving the driver a strong "push back feeling", bringing the feeling of poor vehicle control performance, and even causing safety problems. Hidden danger. Since the target speed cannot be directly given to the system during the actual control of the electric vehicle, the traditional electric vehicle speed setting adopts the linear given method, and the given speed is uniformly added to the ta...
