Electric vehicle speed control device and control method thereof

Abstract

The invention relates to an electric vehicle speed control device and a control method thereof. The electric vehicle speed control device comprises a touch screen control panel and a nixie tube display screen and is characterized by further comprising speed sampling equipment, a voltage reducing and stabilizing circuit, a power supply voltage sampling circuit, a CPU (Central Processing Unit), a voltage reference circuit, a nixie tube display screen driving circuit, a display circuit and a data control circuit, wherein the output end of the speed sampling equipment is connected to the voltage reducing and stabilizing circuit; the voltage reducing and stabilizing circuit is connected to the power supply voltage sampling circuit; the output end of the power supply voltage sampling circuit is respectively connected to the CPU and the voltage reference circuit; and the voltage reference circuit is connected to the display circuit by the nixie tube display screen driving circuit. After the technical scheme is adopted, speed can be directly reflected on the nixie tube display screen by detecting real-time speed of an electric vehicle, and speed limitation can be manually selected on a touch panel.

Description

technical field [0001] The invention belongs to components of an electric vehicle, and in particular relates to a speed control device and a control method for an electric vehicle. Background technique [0002] With the progress of society, human beings are paying more and more attention to the problem of environmental pollution. In the past, motorcycles were a common means of transportation in daily traffic. However, due to their exhaust emissions, they will cause serious air pollution. Many cities in China have also begun to use motorcycles. If restrictions are imposed, electric motorcycles will slowly enter people's field of vision. As the name suggests, electric motorcycles use electric energy as the driving energy, which will greatly reduce the problem of environmental pollution, but the new type of electric motorcycles has just begun. When used in society, many functions have not been fully developed. For example, electric motorcycles are non-motorized vehicles, but in...

[0002] With the progress of society, human beings are paying more and more attention to the problem of environmental pollution. In the past, motorcycles were a common means of transportation in daily traffic. However, due to their exhaust emissions, they will cause serious air pollution. Many cities in China have also begun to use motorcycles. If restrictions are imposed, electric motorcycles will slowly enter people's field of vision. As the name suggests, electric motorcycles use electric energy as the driving energy, which will greatly reduce the problem of environmental pollution, but the new type of electric motorcycles has just begun. When used in society, many functions have not been fully developed. For example, electric motorcycles are non-motorized vehicles, but in fact there are speed limits in different regions. At the same time, because electricity is used as the power source, electric vehicles are not universal in different road sections. working at full speed
