Abstract

The invention discloses a control method for improving the starting comfort of an electric vehicle. The control method comprises the steps: acquiring the highest speed limit of an electric vehicle; setting a fixed speed increment, an initial expected acceleration and initial acceleration execution time; acquiring a target speed and a real-time speed of the electric vehicle from an electric vehiclerotating handle and calculating an acceleration; adjusting the expected acceleration according to the real-time speed; and calculating the acceleration execution time according to the acceleration, the expected acceleration and the initial acceleration execution time. Therefore, the speed of the electric vehicle can be stably increased, and the pause feeling is eliminated.

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 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. At present, the traditional starting control method of electric vehicles adopts the method of adjusting the given rotational speed increment per unit execution time in sections according to the speed, so that the starting acceleration ca...
