Abstract

The invention relates to a vehicular road surface irregularity automatic identification system and method. The vehicular road surface irregularity automatic identification system comprises a perpendicular vibration acceleration sensor, a signal processing module, a hardware system module, a power supply module, a BDM module, a CAN receiving and dispatching module and an automotive CAN bus; the perpendicular vibration acceleration sensor which is connected to a hardware system module through the signal processing module performs communication with the automotive CAN bus through the CAN receiving and dispatching module; the BDM module burns the system debugging and software programs on the hardware system module; the power supply module supplies electricity for the hardware system module. The vehicular road surface irregularity automatic identification system and method has the advantages of being capable of collecting road surface signals through the perpendicular vibration acceleration sensor and obtaining road surface irregularity grades after relevant data processing; providing logic judgment bases for control strategies and enabling an automobile to automatically adjust vehicle modes during driving due to appropriate control algorithm routine selection; and being beneficial to improvement of vehicle riding comfort, controllability and comfort performance.

Description

technical field [0001] The invention relates to the technical field of automatic identification of vehicle road roughness, in particular to a vehicle road surface roughness detection system including hardware system, signal acquisition and processing, and software algorithm, which is especially suitable for detecting the roughness of the road surface currently driving a semi-active / active vehicle Automatic identification system and method. Background technique [0002] With the progress of the times and the development of science and technology, people have higher and higher requirements for the driving safety and comfort of vehicles. Road surface roughness is usually used to describe the degree of undulation of the road surface. To the ride comfort, comfort, safety and other aspects of the vehicle. The research on road surface roughness has also been carried out for decades, and its measurement methods and measurement equipment are also very diverse. However, due to the l...
