A method for collaborative arrangement of vehicle body multi-sensor based on vibration suppression and fusion perception

Abstract

This invention provides a collaborative arrangement method for multiple sensors on a vehicle body based on vibration suppression and fusion perception, belonging to the field of intelligent driving perception technology. The method includes: determining the placement and quantity of cameras and radars based on the vehicle body topology and intelligent driving perception requirements, as an initial placement scheme; constructing a finite element model of the vehicle body based on the initial placement scheme, performing vibration modal simulation, and obtaining the vehicle body vibration frequency spectrum; adjusting the sensor positions based on the sensor natural frequencies and the vehicle body vibration frequency spectrum to avoid resonant frequency bands, generating a sensor placement scheme; verifying the sensor placement scheme, if it does not meet the perception range requirements of intelligent driving, re-determining the positions and quantities of cameras and radars, and updating the initial placement scheme; if it meets the perception range requirements of intelligent driving, constructing a graded vibration reduction connection structure to obtain the final placement scheme. This method achieves a multi-dimensional synergistic improvement in vibration resistance, perception accuracy, and system reliability.
