Layer processing method based on multiple operating systems and vehicle-mounted information machine system

Abstract

The invention provides a layer processing method based on a multi-operation system and a vehicle machine system. The multi-operation system comprises a first system and a second system; and the second system is configured with a target application. The layer processing method comprises the steps that a second system sends a layer display request to a first system according to a wake-up request of a target application, and the layer display request is used for requesting to display a target layer matched with the target application; the first system displays the target layer at the top according to at least one group of display parameters of the pre-configured target layer; the second system performs processing corresponding to a target touch screen event according to the received target touch screen event for the target layer of the first system to obtain a target feedback result; the second system sends the target feedback result to the first system; the first system displays the target feedback result in the target layer; and according to the layer processing method based on the multiple operating systems, the first system can call the target application configured in the second system, and the development and maintenance cost of the target application is reduced.

Description

technical field [0001] The present application relates to the technical field of in-vehicle communication, in particular to a multi-operating system-based layer processing method and an in-vehicle system. Background technique [0002] In order to meet different functional requirements and reduce costs, the car is usually equipped with at least two operating systems, and each operating system has its own characteristics. The hardware sharing between the two operating systems is implemented through a virtual machine manager (such as Hypervisor). At the same time, the two operating systems can transmit data between each other through the channel built by the network or Hypervisor. [0003] Technicians have found that there is usually a compatibility problem between application programs and operating systems, that is, one application program is not suitable for every operating system. The technicians further found that, among the above two operating systems sharing hardware, s...
