[0037] see figure 2 , figure 2 It shows a schematic flow chart of the control method for controlling the steering of the modular flatbed truck in this embodiment, and the control method includes:

[0038] S201, the main controller determines the target angle of each wheel set in the modular flatbed vehicle when turning according to the control signal output by the remote controller and the wheel set information of its corresponding modular unit car sent by each slave controller, and then transmits the control signal to and target angles are sent to the slave controller.

[0039] It should be noted that the wheel set information includes information such as the number of wheel sets, wheelbase and wheelbase of the corresponding modular unit vehicle. The control signals include a mode control signal to control the steering mode and an angle control signal to control the steering angle. Steering modes include front steering, rear steering, normal steering, oblique steering, 9...

Abstract

The invention discloses a controlling system and a controlling method used for controlling veering of a modularization flat car. The controlling system includes a remote-control unit, a main controlling device electrically connected with the remote-control unit and multiple auxiliary controlling devices electrically connected with the main controlling device separately. The remote-control unit andthe main controlling device are both installed on a power module. The multiple auxiliary controlling devices are installed corresponding to multiple modular unit cars one by one. Every auxiliary controlling device is electrically connected with multiple angle sensors separately. The multiple angle sensors are installed corresponding to multiple wheel sets one by one, wherein the multiple wheel sets of the modular unit car corresponding to the auxiliary controlling devices electrically connected with the multiple angle sensors. Every auxiliary controlling device is electrically connected withproportional valves separately, wherein the proportional valves are installed on the wheel sets of the modular unit cars corresponding to the auxiliary controlling devices. According to the controlling system and the controlling method used for controlling veering of the modularization flat car, the problems that in an existing veering controlling method, idle load veering of a car is out of syncand heavy load veering of the car is clamped are solved; veering controlling of the car is well improved; and safety is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle steering control, in particular to a control system and a control method for controlling the steering of a modular flatbed vehicle. Background technique [0002] The modular flatbed truck is a complex-function electromechanical-hydraulic integrated ground vehicle, which is suitable for long-distance transportation of large cargo and on-site transfer of engineering equipment. Equipped with a load-sensitive hydraulic steering system, it applies all-wheel independent steering technology, and has various steering modes such as lateral, oblique, forward, backward, and circling. Modular flatbed trucks, also known as self-propelled modular trucks, have the characteristics of diverse combinations and more flexible transportation forms compared with ordinary heavy-duty transportation flatbed trucks. A modular flatbed truck usually consists of a power module and multiple modular unit trucks. Modular unit ...
