Speed control method of all-electric vehicle top-mounted equipment and all-electric vehicle

Abstract

A speed control method of all-electric vehicle top-mounted equipment includes the steps: when an all-electric vehicle operates in a top-mounted equipment mode, a power takeoff engages a gear, and a gear signal of a speed control switch for regulating target speed of a drive motor is received; whether or not voltage corresponding to the gear signal outputted by the speed control switch is normal is judged; if yes, the drive motor operates at the target speed matching with the gear of the speed control switch until the top-mounted equipment finishes operating; if not, the drive motor is shut down. The invention further discloses the all-electric vehicle employing the method. The speed of the drive motor and that of the power takeoff can be regulated through the speed control switch, one all-electric vehicle chassis can adapt to different top-mounted devices and accordingly can adapt to special vehicles for different purposes, the requirement for platform development of vehicles is met, and the operation requirement of special vehicles which operate with complexity can be well met.

Description

technical field [0001] The invention relates to a speed regulation control method, in particular to a speed regulation control method of pure electric vehicle bodywork equipment. The present invention also relates to a pure electric vehicle for realizing the above method. Background technique [0002] In order to accelerate the development of the new energy vehicle industry, promote energy conservation and emission reduction, and promote air pollution control, the country continues to carry out the promotion and application of new energy vehicles. Among them, pure electric vehicles use high-voltage power batteries as the only energy source, and rely on electric motors to drive vehicles. They have the advantages of zero emissions and low noise. They can be widely used in postal, logistics, sanitation and other fields, and are increasingly valued by the state and enterprises. . Pure electric vehicles can be divided into two categories without top-mounted equipment (such as l...

AI Technical Summary

Problems solved by technology

The corresponding different special-purpose bodywork equipment have different requirements for the operating speed of the PTO 6. The single constant speed control of the pure electric vehicle chassis cannot meet the requirements of the platform-based development of the vehicle model, and cannot well meet the special-purpose vehicle operations with complex movements.
