Abstract

The invention discloses a control method for improving the starting comfort of an electric vehicle. The control method includes: obtaining the maximum speed limit of the electric vehicle; setting a fixed speed increment, an initial expected acceleration, and an execution time of the initial acceleration; Acquire the target speed and real-time speed of the electric vehicle and calculate the acceleration; adjust the expected acceleration according to the real-time speed; calculate the speed-up execution time according to the acceleration, expected acceleration, and initial speed-up execution time, which can make the speed of the electric car increase steadily and eliminate frustration .

Description

technical field [0001] The invention relates to the technical field of electric vehicle control, in particular to a control method for improving the starting comfort of an electric vehicle. 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 being environmentally friendly and convenient to use. [0003] Most of the electric vehicle manufacturers on the market have neglected to improve the driving experience of electric vehicles. Many electric vehicles accelerate too fast when starting, which gives the driver a strong "push on the back", which brings the feeling of poor vehicle handling performance and even causes safety. hidden danger. At present, the traditional electric vehicle starting control method adopts the method of adjusting the increment of the given rotational speed per unit execution time according to the speed segment, which can control the st...
