Abstract: In order to improve driving safety and develop intelligent vehicles, the lane departure warning (LDW) system is designed and developed according to the V-type development process of intelligent network products. According to the safety goal of LDW system, functional safety standard of road vehicle, key use scenario of passenger car, stability and reliability requirements, the LDW system is designed in detail. It defines the system functions and switching conditions, carries out installation and perspective verification, expands the test and experiment process and carries out real vehicle testing on the basis of relevant standards such as JT/T 883－2014, and the design and verification process complement each other. The results show that the system meets the design requirements, can realize the expected function, and has practicability and reliability.
