An intelligent driving system clock control method, apparatus and device, and a storage medium, the method comprising: when an external clock source used by a system clock fails, determining whether there is an available external clock source in a plurality of preset external clock sources; if the available external clock sources exist, determining one of the available external clock sources as a target clock source, and adjusting a system clock to use the target clock source; and if the available external clock source does not exist, continuing to maintain the system clock by using the local RTC clock. A plurality of external clock sources which can be used by a system clock are arranged, so that the system clock is prevented from abruptly jumping subsequently after a signal of a single external clock source is lost; when no available external clock source exists, the system clock can be continuously maintained by using the local RTC clock, so that the technical problem that the use of the intelligent driving system is subsequently influenced due to the stop of the system clock caused by the loss of the external clock source in some scenes in the related technology is solved.

    一种智能驾驶系统时钟的控制方法、装置、设备及存储介质,其包括:在系统时钟所使用的外部时钟源失效时,判断预设的多个外部时钟源中是否存在可用的外部时钟源;若存在可用的外部时钟源,确定所述可用的外部时钟源中的一个为目标时钟源,并调整系统时钟使用所述目标时钟源;若不存在可用的外部时钟源,使用本地RTC时钟继续维持所述系统时钟。通过设置多个可供系统时钟使用的多个外部时钟源,避免单个外部时钟源信号丢失后导致系统时钟在后续出现剧烈跳变;当没有一个可用的外部时钟源时,本申请则可通过使用本地RTC时钟继续维持系统时钟,解决了相关技术中在某些场景下因外部时钟源的丢失导致系统时钟停止,后续影响智能驾驶系统使用的技术问题。
