Description

technical field

[0001] The invention relates to an electronic control device for steering operation of a vehicle, in particular to an electronically controlled steering device for a forklift. Background technique

[0002] With the continuous improvement of industrial automation, people put forward higher requirements for the comfort, safety and reliability of vehicle driving. This is especially true for some transport vehicles. Since the goods to be transported by these vehicles are relatively heavy, if it is realized only by operating the mechanical steering structure, it will not only be laborious, but also when driving on a bumpy road, the operating handle is easy to shake from side to side. It makes the vehicle difficult to control.

[0003] An article titled Application of Electronic Power Steering Control Devices in Electric Forklifts was published in the Journal of Chinese Mechanical Engineers. The steering device consists of steering wheel, stepper motor, AC steerin...
