Design And Implementation Of Safety And Credible Vehicle Electronic Software Remote Repair System

With the rapid development of computer technology and the progress in automotive manufacturing, vehicle enters the intellectualized development era as an efficient transport. Vehicle becomes a four-wheel drive intelligent system now. On the modern cars, the window control and door control, monitor and control of the engine running, are all controlled by vehicle software system, which make the vehicle software system more and more complex. Vehicle software becomes more and more powerful, on-board software system code is also increasing. This led to the vehicle automobile software failure rate rising, more and more vehicles recall is due to the on-board software malfunction. Nowadays, maintenance of vehicle software after the vehicle leaving car factory is still not very good break. Vehicle recall costs manpower and resources, does not meet the requirements of modern technology, and is not in the interest of the manufacturers and users also. To achieve remote vehicle-mounted software upgrades, becomes the problem of automobile software maintenance.This paper introduces the trusted network into the remote maintenance of automobile software, and provides the combination of trusted network and repairing network. We also provide a safe and reliable repair network environment based on the trusted network, realize a safe, reliable, simple and efficient vehicle-mounted software remote repair system. Firstly, this paper introduced the knowledge of trusted network and trusted network connection. Trusted network is a new kind of network security technology based on the existing network security and trusted network measure whether the action is safe. It strengthen the network security management, constructing a trusted network environment based on the existing unsafe network; Trusted network connect ion controls network security form the source, and ensures access network terminal credibility through the trusted connect validation control the access of terminal equipments. Then, this paper introduced knowledge of embedded system and embedded systems in the vehicle-mounted system application:Embedded technology in automotive electronic technology is widely used, the chassis security, control, monitoring and in-car entertainment system are inseparable from the support of the embedded technology. The embedded system is the combination software and hardware, to realize vehicle software remote repair, embedded system must be repaired. At last, this paper introduced the design and realization of the safety and credible vehicle electronic software remote repair system.The remote repair system proposed in the article adapt to the development of computer technology and vehicle industry. The system proposes a good way of vehicle on-board software remote repair and realizes the vehicle maintenance after the vehicle leaving the vehicle factory. Along with the popularization of the wireless network and the propulsion of vehicle intelligent, this system has a vast and wonderful application prospect.
