The invention relates to the technical field of vehicle control, in particular to a vehicle, a limp home circuit and a control method thereof.The limp home circuit comprises a power module, a driving module, a latch module and a control module, and the power module is used for supplying power to the driving module, the latch module and the control module; the control module is used for generating a driving control signal based on a current control demand; the latch module is used for generating another driving control signal when the control module is in the fault state; and the driving module is used for generating corresponding driving signals according to different driving control signals, and driving corresponding different limp home demand loads according to different driving signals. According to the limp home circuit provided by the embodiment of the invention, the driving signal output by the control module is effectively latched, and when the electric control system breaks down, the stable driving signal is output to drive the corresponding load, so that the safety of the vehicle is improved.
本发明涉及车辆控制技术领域,特别涉及一种车辆、limp home电路及其控制方法,电路包括:电源模块、驱动模块、锁存模块和控制模块,其中,电源模块用于为驱动模块、锁存模块和控制模块供电;控制模块用于基于当前控制需求生成驱动控制信号;锁存模块用于在控制模块处于故障状态时,生成另一驱动控制信号;驱动模块用于根据不同驱动控制信号生成对应驱动信号,并根据不同驱动信号驱动对应的不同limp home需求负载。根据本发明实施例的limp home电路,通过将控制模块输出的驱动信号进行有效锁存,在电控系统出现故障时,输出稳定的驱动信号驱动相应的负载,提高车辆的安全性。
