Problems solved by technology

These electric steering controllers can only perform simple steering control, the operation feel is not ideal, and they do not have various comprehensive safety protection measures. When the system fails, they cannot make accurate judgments, but simply disconnect the main power supply. It will cause the operator to be unclear about the fault, unable to repair the fault in time, affecting normal work, and causing great safety hazards

Description

technical field [0001] The invention relates to an electric power steering control circuit, in particular to an intelligent electric power steering controller for a cargo handling vehicle. Background technique [0002] The steering part of traditional cargo trucks mostly adopts mechanical steering. With the continuous increase of the truck body and the continuous improvement of the load-bearing capacity, this kind of truck that uses a mechanical structure for steering is not only laborious to operate, but also difficult to operate under various bumps. The ground is smooth and smooth, especially when turning at low speeds, I feel that the direction is relatively heavy. Make the driver easily fatigue when driving, reducing work efficiency. [0003] With the popularization of industrial automation, people have put forward higher requirements for the intelligence, energy saving and safety of cargo handling vehicles. Various electric power steering systems that follow gradually...
