Distributed task scheduling method and system based on vehicle-mounted Ethernet

The invention discloses a distributed task scheduling method and system based on a vehicle-mounted Ethernet, and the method comprises the following steps: S1, when each domain controller is awakened, a task scheduling instance deployed in each domain controller registers in a task scheduling center, and actively pulls and updates a task list; s2, a user performs task setting through the in-car entertainment system, and the in-car entertainment system synchronizes setting information to a task scheduling center; s3, the task scheduling center receives task information set by a user, updates a task list, and informs each registered online domain task scheduling instance to update the task list; s4, the task scheduling center and the task scheduling instance in the power-on state scan a task list at the same time; and S5, after the task execution triggering condition is met, the task scheduling instance calls the task, and the service is executed to control the vehicle. Tasks are managed and scheduled in a unifi
