Problems solved by technology

With the research on the structure, the research on the structural connection and support of the suspension system is becoming more and more mature, but for the comfort adjustment, the cab suspension still does not play its due role. The existing automobile cab suspension system adjustment After passing through the road conditions, according to the jumping amount of the cab, the suspension system will respond passively, follow-up, and open-loop to slow down the speed caused by the road conditions, the driving environment, the speed of the driver’s steering wheel, the speed of the car, and There is a serious hysteresis due to the vibration caused by the aging condition of the vehicle

Embodiment

[0024] In this embodiment, the driving is gentle road condition, driving on the expressway;

[0025] According to the new car adjustment, the parameters input to the ECU data sorting center are set as follows:

[0026] The setting mode for the expressway is a comfortable driving mode, and its comfort evaluation standard is the amplitude A of the driver's position 1 Vibration frequency f 1 , synchronously to achieve this standard, the calibrated shock absorber damping is C 1 , the spring stiffness is K 1 ,.

[0027] The criteria for judging road conditions on high roads are:

[0028] 1. Expressway entrance indication; expressway special isolation zone and other signs

[0029] 2. The continuous amplitude of the spring within 10 cycles is ≤10mm

[0030] When the vehicle is driving on the road, the video collector 101 will collect road condition video in real time, and screen special road conditions and special signs according to the system settings. If the continuous ampli...

Abstract

The invention belongs to the technical field of automobile manufacturing, and relates to an active self-adaptive cab suspension system which comprises a data acquisition system, an energy system, a vehicle-mounted AI processor, an ECU data processing center and a response system. The data acquisition system is used for acquiring vehicle driving information including road condition information, driving sign information and vehicle information, and the energy system is used for providing energy for the whole system. The vehicle-mounted AI processor is used for comparing collected vehicle driving information with driver comfort standard information set in the earlier stage and carrying out iterative upgrading on a logic algorithm set in the earlier stage of the ECU data processing center, the ECU data processing center is used for carrying out operation processing on the collected information, and the response system is used for adjusting the rigidity of the cab suspension. Compared with a conventional suspension system, the system can actively carry out real-time adjustment in advance in a closed-loop manner according to the vehicle driving road condition and environment, driver operation and the vehicle aging degree.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing and relates to an active adaptive cab suspension system. Background technique [0002] The cab suspension system is mainly used for reliable connection and vibration reduction between the frame and the cab. With the continuous development of commercial vehicle technology, the role of cab suspension has been continuously expanded and improved, and it has become a key system to achieve many important performances of the vehicle. With the research on the structure, the research on the structural connection and support of the suspension system is becoming more and more mature, but for the comfort adjustment, the cab suspension still does not play its due role. The existing automobile cab suspension system adjustment After passing through the road conditions, according to the jumping amount of the cab, the suspension system will respond passively, follow-up, and open-loop to slow down...
