汽车电子稳定程序控制系统(ESP)是汽车安全技术发展的重要研究方向。ESP系统结构复杂,信息处理量大,因此快速、准确完成极限状态下车辆的控制成为技术难点。文章针对新型ESP系统在传感器接口设计、总线信息传输、控制策略等方面的关键技术进行了深入研究,提出了一种基于CAN总线的ESP测控系统设计方案。
Automotive Electronic Stability Program Control System (ESP) is an important research direction for the development of automotive safety technology. Because of the complex structure and large amount of information processing, the ESP system has become a technical challenge to quickly and accurately control the vehicle under extreme conditions. In this paper, the key technologies of the new ESP system in sensor interface design, bus information transmission and control strategy are deeply studied, and a design scheme of ESP measurement and control system based on CAN bus is proposed.
