Abstract

The invention proposes a controlling method for an electric car. The method comprises the following steps: detecting whether the position of a shift lever of the car is changed or not; if the position of the shift lever is changed, judging the state of the car according to the present position and the prior position of the shift lever, and detecting the present speed of the car; if the car is in the first state, comparing the present speed with the first predetermined speed; if the speed is smaller than or equal to the first predetermined speed, adjusting the present speed to the first predetermined speed, otherwise, calculating a target gear of an automatic gearbox according to the present speed; judging whether the target gear is the same as the present gear or not; if the target gear is different from the present gear, matching the automatic gearbox to the target gear, otherwise, adjusting the present speed directly according to a control signal of a driver. The controlling method of the invention can be used for automatically controlling the speed of the electric car when the gear is shifted, the car is prevented from sliding forth and back, sufficient reacting time for a driver to correct false operation behaviors is given, and the driving safety of the car is improved.

Description

technical field [0001] The invention relates to the technical field of automatic control of automobiles, in particular to a control method for electric automobiles. Background technique [0002] With the development of pure electric drive vehicle manufacturing and control technology, vehicle electronic control has become one of the three key technologies of pure electric drive vehicles. In the process of starting and stopping, it is very convenient to design a control strategy to prevent the vehicle from rolling back. [0003] But the above prior art is basically all only aimed at the link of starting or parking, and does not carry out comprehensive management and control to each gear shifting process of the automobile, thereby the safety of the vehicle cannot be guaranteed in all directions. Contents of the invention [0004] The aim of the present invention is to solve at least one of said technical drawbacks. [0005] For this reason, the object of the present inventi...
