摘要
随着汽车电子技术的迅猛发展,用户对汽车智能化的要求越来越高。远程启动发动机以实现车内提前制冷,已成为广大汽车用户的刚需。文章介绍基于功能安全的远程启动系统的基本构成和逻辑流程,同时进行该功能的危害分析和风险评估,制定对应的安全策略。最后举例排挡设计对应的测试用例,采用CAN总线注入故障的方法,验证安全策略有效性,为汽车功能安全的设计开发提供参考。
With the rapid development of automotive electronics technology,users'requirements for automotive intelligence are increasing.Remote start vehicle to achieve cooling in advance has become a rigid demand for the majority of automotive users.This article introduces the basic structure and logic flow of the remote start system based on functional safety,conducts hazard analysis and threat and risk assessment of the function and formulates corresponding safety strategies.Finally,the test case corresponding to the gear design is exemplified,and the CAN bus injection fault method is used to verify the effectiveness of the safety strategy,which provides a reference for the development of automotive functional safety.
