In the paper,a method is proposed,which can improve the accuracy of laser ranging for hybrid electric vehicles in the internet of vehicles by combining pulse laser ranging with MEMS sensors.This method can reduce the interference error caused by the rising edge delay of MEMS acceleration pulse of hybrid electric vehicle and the information transmission noise error caused by the amplitude fluctuation of echo signal of pulse laser ranging system.In addition,a theoretical code of pulse laser ranging and MEMS sensor register configuration is proposed.The pulse laser ranging method can avoid the inherent "dynamic multi threshold" error caused by the limited load bearing capacity of electronic components.Compared with the existing "phase type" laser ranging method,it has the advantages of high accuracy,low cost,stable performance,environmental protection and safety.Through the verification of the data sampling test of the internet of vehicles,the laser ranging accuracy is as high as 0.798°,the interference error is only ±0.001,and the echo signal amplitude error is only about 15 cm.Therefore,it can realize fast,high-precision and wide range "dynamic" and "static" laser ranging.
