Embodiment Construction

[0038] The specific embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] Such as figure 1 As shown, a control method of a hydraulic flatbed transport vehicle includes a walking separation control method, a steering synchronous control method and a suspension synchronous control method.

[0040] The traveling separation control method is a method of separately controlling the engine, the traveling pump and the driving motor.

[0041] The steering synchronous control method is a control method combining a steering PID control algorithm with common feedback synchronous error correction. The specific method steps are as follows:

[0042] Step 1, such as figure 2 As shown, first, each wheel train performs a separate steering angle PID control output according to the steering angle set value, and uses the steering angle feedback of this gear train to complete the steering angle closed-loop control...

Abstract

The invention discloses a hydraulic flat transporter control method. The hydraulic flat transporter control method comprises a running separated control method, a steering synchronous control method and a suspension synchronous control method. The running separated control method is a method for respectively controlling an engine, a running pump and a driving motor. The steering synchronous control method is a control method that combines a steering PID control algorithm and common feedback synchronous error correction. The suspension synchronous control method is a control method that combines a suspension PID control algorithm and common feedback synchronous error correction. The hydraulic flat transporter control method has the advantages that the stability of a running system is enhanced, the whole vehicle steering is rapid and integrated, the clamping stagnation phenomenon is avoided, the suspension height adjusting speed is high and the balancing performance is good.

Description

technical field [0001] The invention relates to the control strategy of the three major systems of traveling, steering and suspension of a transport vehicle, in particular to a control method of a hydraulic flat transport vehicle. Background technique [0002] The hydraulic platform transport vehicle is widely used in the transfer of steel structure hull sections in shipyards between various processes, and is also suitable for the transportation of large steel plants and super-large concrete prefabricated components on roads (railways). The development of heavy-duty engineering transport flatbed trucks has a history of 100 years abroad, but imported hydraulic flatbed trucks are expensive, maintenance and repair costs are high, and foreign products are updated quickly, resulting in inconvenient maintenance and long cycle, which affects the improvement of production efficiency. With the development of my country's shipbuilding industry, relevant domestic manufacturers have dev...
