The invention discloses a driving circuit, device and method of an automobile load, and relates to the technical field of automobile load driving, the driving circuit of the automobile load comprises a first control circuit, a second control circuit and a driver, the first control circuit is connected with the second control circuit, the first control circuit and the second control circuit are both connected with the driver, and the driver is connected with the first control circuit. When the first control circuit is normal, the first control circuit controls the second control circuit to sleep and controls the driver to drive the load; when the first control circuit breaks down, the first control circuit wakes up the second control circuit, the second control circuit controls the driver to drive the load, the second control circuit is a redundant circuit, the driver can be controlled to drive the load when the first control circuit breaks down, and the function of a key execution component is maintained. The condition that the controller fails or fails to drive the circuit and the execution assembly to lose control is avoided, the fault-tolerant capability and reliability of the system are improved, and the driving safety is ensured.
本发明公开了一种汽车负载的驱动电路、装置及方法,涉及汽车负载驱动技术领域,所述汽车负载的驱动电路包括第一控制电路、第二控制电路、驱动器,第一控制电路与第二控制电路连接,第一控制电路和第二控制电路均与驱动器连接,当第一控制电路正常时,第一控制电路控制第二控制电路休眠并控制驱动器驱动负载;当第一控制电路故障时,第一控制电路唤醒第二控制电路,使第二控制电路控制驱动器驱动负载,第二控制电路为冗余电路,可在第一控制电路故障时控制驱动器驱动负载,维持关键执行部件的功能,避免了控制器故障或失效驱动电路和执行组件失去控制的情况,提高了系统的容错能力和可靠性,保证了行车安全。
