Abstract

The invention discloses an electric vehicle speed control method which comprises the steps that a remote communication terminal T-Box of an electric vehicle sends driving data of the electric vehicleto a server, and the server generates a current driving path of the electric vehicle according to the driving data of the electric vehicle and pre-stored electronic map information and determines pathcharacteristics. And the T-Box receives the plurality of speed limit values issued by the server for several times and the speed limit target of the current driving path of the electric vehicle, anddetermines the speed reduction step length according to the size relationship between the speed limit value issued by the server each time and the current driving speed of the electric vehicle. And the speed reduction step length, the speed limiting value and the speed limiting target are sent to a controller of the electric vehicle so that the controller can adjust the current running speed of the electric vehicle in real time till the current running speed of the electric vehicle is lower than the speed limiting value and lower than the speed limiting target. According to the technical scheme, double safety guarantees are achieved for control over the vehicle speed of the electric vehicle, and meanwhile the reliability of vehicle speed control is improved.

Description

technical field [0001] The present application relates to the technical field of electric vehicles, in particular to a method and system for controlling the speed of an electric vehicle. Background technique [0002] With the rapid development of social economy and the continuous improvement of people's living standards, the number of cars per capita is also showing a trend of increasing year by year, and the situation of road traffic congestion is becoming more and more serious. Therefore, more and more people choose two-wheel or three-wheel electric vehicles as a means of transportation for short-distance travel, in order to avoid road congestion and increase travel time. However, due to factors such as the crowded roads and time constraints of electric vehicles, electric vehicle drivers often drive at a relatively fast speed, which brings great potential danger to road traffic participants. Therefore, it is necessary to effectively control the driving speed of the electr...
