Description

technical field [0001] The invention belongs to detection devices and methods, in particular to a commercial vehicle dynamic slope test system and a test method thereof. Background technique [0002] At present, most of the inclinometers we use simply use the inclination sensor to measure the inclination angle of a certain contact surface or object. Due to its poor real-time response, most application fields are in engineering construction or in static environments. However, problems such as data delay or data jitter will occur in dynamic measurement. With the deepening of the intelligent development of commercial vehicles and the popularization of equipment such as electronically controlled engines, automatic transmissions, body controllers, and electronically controlled air suspensions, commercial vehicles need to collect many signals from the body itself to respond to changes in surrounding working conditions in real time In order to coordinate the working status of the ...

AI Technical Summary

Problems solved by technology

However, due to the large size and heavy weight of the commercial vehicle itself, the worse driving conditions, the volume of the traditional slope measurement instrument is too large, and because the data processing is not suitable for dynamic measurement, the measurement data is very noisy, so the commercial vehicle slope measurement cannot adopt the traditional method. Single inclinometer acquisition

Use a traditional slope tester to measure vehicle dynamic slope changes. Due to vehicle bumps, turning rolls, etc., the complex working conditions of the vehicle will cause a lot of noise regardless of the measurement method, and it is impossible to accurately feed back real-time slope information.
