The invention discloses an L3 intelligent driving power grid system and a vehicle, and relates to the technical field of electronics and the field of intelligent driving. By adopting the L3 intelligent driving power grid system and the vehicle disclosed by the invention, the L3 intelligent driving power grid system is split into a first power grid system and a second power grid system, and vehiclesafety integrity level splitting is carried out on modules in the two subsystems at the same time, so that the safety performance of the L3 intelligent driving power grid system meets the requirementof ASIL D level. Besides, the first power grid system and the second power grid system are adopted for double-circuit isolated power supply to guarantee that when any system fails, the other system serves as a standby power supply system, normal power supply of a power-assisted steering module, a safety control module and a power-assisted brake module is maintained, and the safety driving coefficient of the whole vehicle is increased.
本发明公开了L3智能驾驶电网系统及车辆,涉及电子技术领域,还涉及智能驾驶领域。采用本发明公开的L3智能驾驶电网系统及车辆,通过将L3智能驾驶电网系统拆分为第一电网系统和第二电网系统两个子系统,同时对两个子系统中的模块进行汽车安全完整性等级拆分,以使得L3智能驾驶电网系统安全性能达到ASIL D级的要求。此外,采用第一电网系统和第二电网系统双路隔离供电,保证在任意一个系统失效时,另一个系统作为其备用供电系统,维持转向助力模块、安全控制模块和刹车助力模块的供电正常,提高整车的安全驾驶系数。
