Horizontal control system and method for vehicle platform

Abstract

The invention relates to a horizontal control system for a vehicle platform. The system is characterized by comprising a tilt sensor (1), a programmable controller (3) and a proportional valve (4), wherein ports Can-H and Can-L of the tilt sensor (1) are connected with ports Can-H and Can-L of the programmable controller (3) through a double-stranded wire (2), and the proportional valve (4) is connected with the PWM (pulse-width modulation) output port of the programmable controller (3). By the adoption of the horizontal control system, by mounting the tilt sensor on a vehicle to obtain an inclined angle, and by the adoption of the programmable controller and the proportional valve, the inclination of the vehicle is adjusted, the vehicle is enabled to be horizontally maintained, and by the adoption of the system, the leveling of the vehicle platform is enabled to be faster, more stable and more accurate.

Description

technical field [0001] The invention relates to a vehicle platform level control system and method thereof, which are suitable for heavy transport vehicles with hydraulic suspension systems. Background technique [0002] Heavy-duty transport vehicles have a large load capacity, generally more than 50 tons. When driving on a slope, because the vehicle platform is not in a horizontal state, the goods are easy to slip and cause damage to the goods. Therefore, a platform level control system is needed to ensure that the vehicle platform is always in a horizontal state during transportation and ensure the safety of goods. At present, the inclination angle is generally fed back through the inclination sensor, and the automatic leveling of the platform is realized through a proportional valve combined with a closed-loop control algorithm such as PID. However, the conventional PID algorithm uses the tilt angle as a feedback signal to calculate the leveling control current and contr...

Problems solved by technology

However, the conventional PID algorithm uses the tilt angle as the feedback signal to calculate the leveling control current and control the opening of the proportional valve, which will cause the leveling system to be inaccurate and not timely.
