Electric vehicle double-motor drive controlling device

Abstract

The invention discloses an electric vehicle double-motor drive controlling device in the technical field of motor drive controlling devices. The electric vehicle double-motor drive controlling devicecomprises a shell. A heat dissipation fan is embedded in the right side of the shell. Integrally formed heat dissipation fins are uniformly arranged at the top and bottom of the shell. An electric relay, a storage battery, a single chip micro-computer controller and a front wheel motor driving machine are sequentially mounted on the top of an inner cavity of the shell from left to right by bolts.According to the electric vehicle double-motor drive controlling device, independent front and rear wheel motor driving machines are mounted, and independent controlling of electric vehicle front andrear wheels is achieved. A temperature sensor and a soaking sensor are arranged in the shell of the controlling device to detect whether the controlling device is influenced by high temperature or water during application. Power dump is conducted when the device is at a high temperature or in water, and therefore the device is protected. A accelerated speed sensor is arranged to detect posture ofthe parked vehicle. When the vehicle is turned over, alarming sound is sent to promote a user to place the turned-over vehicle in time.

Description

technical field [0001] The invention relates to the technical field of motor drive control devices, in particular to a dual motor drive control device for electric vehicles. Background technique [0002] The electric vehicle controller is the core control device used to control the start, operation, advance and retreat, speed, stop and other electronic devices of the electric vehicle motor. It is like the brain of the electric vehicle and an important part of the electric vehicle. At present, electric vehicles mainly include electric bicycles, electric two-wheeled motorcycles, electric tricycles, electric three-wheeled motorcycles, electric four-wheeled vehicles, battery cars, etc. Electric vehicle controllers also have different performance and characteristics due to different models. . At present, the existing electric vehicle drive control device only emphasizes its control function, but lacks the corresponding protection function. When the electric vehicle is attacked b...

Problems solved by technology

[0003] The purpose of the present invention is to provide a dual-motor drive control device for an electric vehicle to solve the problem that the existing electric vehicle drive control device proposed in the above background technology only emphasizes its control function and lacks corresponding protection functions. There is no corresponding detection function when high temperature or water is invaded, and the wheel running cannot be stopped in time to protect the safety of the vehicle. In addition, when the vehicle is bumped and dumped during parking, there is no corresponding alarm device to remind the user The problem of placing vehicles in time
