Abstract:To achieve timely updates and remote debugging for hybrid commercial vehicles cruise controllers, and to ensure the safety of the system , an over the air technology (OTA) system based on the user datagram protocol (UDP) is designed and developed,which it includes the communication module, handshake module, command line debugging module, file download module, backup and upgrade module, and server interface of the OTA system. Testing and verification results show that the hybrid commercial vehicle cruise controller OTA system based on UDP protocol can accomplish the functions of message transmission, communication encryption, system debugging, software package transmission, software upgrade and backup, achieving the security, reliability, and convenience of software upgrade.
