Abstract

The invention relates to a height sensor calibration method, device and equipment, an electric control air suspension and a vehicle, and the method comprises the steps: entering a calibration mode ifa height sensor calibration identification is not obtained; in the calibration mode, in the process of calibrating and adjusting the height of the detected object, acquiring coil charging data of theheight sensor; determining a working mode to which the height sensor belongs according to a preset association relationship between the coil charging data and the working mode of the height sensor; and calibrating the height sensor according to the working mode so as to carry out actual adjustment on the height of the detected object according to the working mode. By the adoption of the technicalscheme, the tedious degree of the installation and calibration process of the height sensor can be reduced, and the installation and calibration efficiency of the height sensor is improved.

Description

technical field [0001] The invention relates to the technical field of height sensors, in particular to a height sensor calibration method, device, equipment, electronically controlled air suspension and a vehicle. Background technique [0002] Electronically Controlled Air Suspension (ECAS) can ensure the stability of the vehicle body, improve the vehicle's passability on different road surfaces and adapt to different loads. in, figure 1 It is a schematic diagram of the structure of ECAS, such as figure 1 As shown, the ECAS can include a suspension 1, a wheel bracket 2, a wheel 3, an air spring 4, a shock absorber 5, a height sensor 6, a swing rod 7, a solenoid valve 8, an air tank 9, and an electronic control unit (Electronic Control Unit , ECU) 10, air circuit 11, signal line 12. The height sensor 6 is installed on the suspension 1 and connected to the axle through the swing rod 7; when the height of the vehicle body and the axle changes, the height sensor 6 will colle...
