摘要
针对传统分布式赛车电子电气架构存在线束杂乱和整车复用性低等问题,提出了FSAC赛车中央网关+域控制器电子电气架构的设计方案。根据FSAC赛事规则进行中央网关和域控制器的硬件设计及软件设计,对此架构进行离线丢包测试和时延测试,并将中央网关和域控制器布置于赛车上进行基础功能测试和功能性验证。结果表明:中央网关以太网在数据间隔25ms以上时未出现丢包,在通信过程中平均延时小于3ms,满足可靠性、实时性要求;赛通信良好未出现数据的误传、漏传、阻塞、系统卡死等现象,中央网关+域控制器在相同动态任务下对资源占用率明显低于传统分布式架构。
The electronic and electrical architectures of traditional distributed racing cars face issues of disordered wire harnesses and low vehicle reusability.Therefore,an electronic and electrical architec-ture design scheme of the central gateway+domain controller for the FSAC racing car was proposed.Ac-cording to the FSAC race rules,the hardware and software design of the central gateway and domain controllers was carried out.Offline packet loss test and delay test were conducted on this architecture,and the central gateway and domain controller were arranged on the racing car for basic function test and functional verification.The experimental results show that the central gateway Ethernet does not ex-perience packet loss when the data interval exceeds 25 ms,and the average delay during communica-tion is less than 3 ms,meeting the reliability and real-time requirements.The racing car’s communica-tion is satisfactory,with no instances of data misdelivery,leakage,blocking,system freezing,or other is-sues.Compared with the traditional distributed architecture,the central gateway+domain controller have significantly lower resource utilization rates under the same dynamic tasks.
