Problems solved by technology
In the prior art, the steering of the tires on the axles of the electric flatbed is controlled by the working current of the steering proportional valve. During the steering process, the tires on each axle are in different states due to friction, tire pressure, and oil cylinder pressure. Therefore, if the same steering proportional valve current is used, the steering speed of each axle tire will be inconsistent, resulting in serious tire wear and low steering accuracy of the electric flatbed

Embodiment Construction
[0059] Below, the attached drawing will be described in detail according to the example of this application. Obviously, the embodiment described is only a part of the implementation example of this application, not all the embodiments of this application. It should be understood that this application is not limited by the example embodiments described here.
[0060] figure 1 The process schematic diagram of the steering control method provided by the application for examples of this application. The steering control method can be applied to an electric flat car. The electric flat car can include multiple groups of bridges. Each group of bridges is equipped with wheels. The steering control method can be used to control the wheels of multiple bridges synchronizing steering. Specific, such as figure 1 Show, the steering control method can include:

The invention relates to a steering control method and device and an electric flat car, and relates to the technical field of logistics equipment.The steering control method comprises the steps that a control instruction is received to obtain target steering angles of wheels on different axles; current steering angles of wheels on different axles are obtained; according to each current steering angle and the corresponding target steering angle, target currents of a plurality of steering proportional valves are obtained; and the multiple steering proportional valves are controlled to work at the corresponding target currents, so that the wheels of the multiple sets of axles synchronously steer to the corresponding target steering angles. According to the steering control method and device and the electric flat car, tire abrasion can be reduced, and the steering precision of the electric flat car can be improved.
Description
Technical field [0001] This application involves the field of logistics equipment technology, which specifically involves a steering control method, device and electric tablet car. Background technique [0002] Electric tablets are powered by lithium iron phosphate batteries, and motors are driven by transportation for transportation. In existing technologies, the tire steering of the bridge of the electric tablet is controlled through the working current of the steering ratio valve. During the steering process, due to the friction, tire pressure, oil cylinder pressure, etc. due to the turning of the tires of each car and bridge. Therefore, using the same steering ratio valve current will cause inconsistent steering speeds of the tires of each vehicle and bridge, which will cause severe tire wear and low steering accuracy of the electric tablet car. Invention content [0003] In order to solve the above technical problems, the embodiments of this application provides a steering ...
