Background
The controller is a master device for controlling the starting, speed regulation, braking and reversing of the motor by changing the wiring of a main circuit or a control circuit and changing the resistance value in the circuit according to a preset sequence. The system consists of a program counter, an instruction register, an instruction decoder, a time sequence generator and an operation controller, and is a decision mechanism for issuing commands, namely, the decision mechanism is used for coordinating and commanding the operation of the whole computer system. The electric vehicle controller is a core control device used for controlling the starting, running, advancing and retreating, speed and stopping of a motor of the electric vehicle and other electronic devices of the electric vehicle.
Because the mobility of the electric vehicle is large, the electric vehicle can be used in almost any place, and the vibration impact on the electric vehicle controller is large in the driving process, so that the protection on the electric vehicle controller is also important. Generally speaking the controller is mostly through a damping device fixed mounting in the inside of electric motor car, and damping device adopts the spring to come the shock attenuation more, and the absorbing range lacks the restriction, and the shock attenuation effect is unsatisfactory, and is not hard up easily. Moreover, the controller is installed on the vibration damper through the bolt, and is inconvenient to disassemble.
