Development of Synchronous Collection System for Road Environment and Driving Behavior Data
The high-precision,portable,and multi-dimensional driving environment data of vehicles in transit and their surround-ings play a crucial role in the fields of the L3 level and above autonomous vehicle scenario library testing,bad driving behavior spec-trum construction,and real-time traffic control in transit.The data acquisition system composed of single sensor is greatly limited in accuracy and dimension,resulting in low reliability.In order to realize the collaborative integration of multiple types of data sensors,a multi-module and road environment data and driving behavior synchronous acquisition system including lidar,vehicle motion meas-urement and combined positioning,vehicle pedal and steering wheel displacement sensor and Rayleigh integrated machine was designed and developed.It supports the parallel processing of multiple traffic data collection tasks,integrates the real driving behavior of us-ers,and designs a data real vehicle collection platform for a certain IVECO model based on this system.The system is composed of two subsystems of upper computer and lower computer,integrating the multi-module data acquisition,storage,transmission and cali-bration functions,and completing the time synchronization processing for each module,it is suitable for"tourist chartered buses,Lin-er buses and dangerous goods transport vehicles"scenario,and designes the easy-to-operate upper computer user interface,real-time visualization of multi-module data,intuitive view of the data variation law in each period,with a high application value.
