The invention discloses a driving circuit, a control method and a vehicle. The driving circuit comprises a driving module, a high-side circuit and a low-side circuit, the high-side circuit comprises a first switching tube; the low-side circuit comprises a second switch tube; the second end of the high-side circuit is connected with the first end of the load, and the first end of the low-side circuit is connected with the second end of the load; the driving module is connected with the first switching tube and the second switching tube and is used for outputting a driving signal to the first switching tube and the second switching tube; and the driving module is also used for diagnosing an overcurrent fault, a short-circuit-to-power fault, a short-circuit-to-ground fault and a load open-circuit fault. According to the driving circuit, the fault occurrence type can be accurately judged, and missing report and false report in fault diagnosis can be avoided to the greatest extent. And a high-side circuit and/or a low-side circuit are/is turned off in time, so that facilities such as a load are protected from being damaged.
本发明公开了一种驱动电路、控制方法及车辆,该电路包括:驱动模块、高边电路和低边电路;高边电路包括第一开关管;低边电路包括第二开关管;高边电路的第二端连接负载的第一端,低边电路的第一端连接负载的第二端;驱动模块连接第一开关管和第二开关管,用于输出驱动信号至第一开关管和第二开关管;驱动模块还用于对过流故障、短路到电源故障、短路到地故障和负载开路故障进行诊断。本发明的驱动电路可以精准判断故障发生类型,最大程度避免故障诊断中的漏报和误报。并及时关断高边电路和/或低边电路,从而保护负载等设施不被损坏。
