[0029] The present invention will be further described below in conjunction with the drawings and specific implementations:
[0030] The invention relates to a body attitude leveling control system of an emergency rescue vehicle especially in low-speed off-road driving. The leveling system includes a three-axis accelerometer, a data processor, a controller, an electro-hydraulic proportional valve, a displacement sensor and a suspension Hydraulic cylinder. The three-axis accelerometer can measure the acceleration of low-speed vehicles in real time; the processor calculates the vehicle body attitude angle according to the acceleration measured by the three-axis accelerometer; the controller can read the body attitude angle information, and compare the body attitude angle with The leveling accuracy preset angle of the vehicle is compared in real time to determine whether the vehicle body needs leveling control, so as to level the vehicle body. The system can adopt the centroid posi...
