In order to improve the quality and reliability of in-vehicle communication, in-vehicle visible light communication technology is introduced by analyzing the influence of infrastructure-vehicle channel transmission model and road infrastructure parameters. Based on the line-of-sight channel between the infrastructure and the vehicle, a model is established to analyze the communication loss during signal transmission. Closed-form analytical equation of the system performance are derived by using the line-of-sight communication Bit Error Rate (BER), downtime probability, and the Block Error Rate (BLER). The effect of the composite pointing error on BER, downtime probability, and BLER of the line-of-sight communication system is analyzed. The experimental results show that: under the no-fading and line-of-sight transmission conditions, increase the height of the street light reduces the BER, while increasing the communication link distance increases the BER; raising the downtime threshold reduces the downtime probability of the line-of-sight link; increasing in the number of transmitted bit blocks helps to improve the performance of BLER; when the number of BER blocks is increased, the system’s BLER decreases rapidly; after considering the pointing errors, BER, downtime probability and BLER all increase, which indicates that pointing error has a debilitating effect on the system communication.
