Multi-operating system-based layer processing method and vehicle-machine system

Abstract

The present application provides a layer processing method and vehicle-machine system based on multiple operating systems. The multiple operating systems include a first system and a second system; the second system is configured with a target application; the layer processing method includes: the second system according to The wake-up request of the target application sends a layer display request to the first system, and the layer display request is used to request to display the target layer matching the target application; the first system tops according to at least one set of display parameters of the pre-configured target layer Display the target layer; the second system performs processing corresponding to the target touch screen event according to the received target touch screen event for the target layer of the first system to obtain the 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; the multi-operating system-based layer processing method can realize the call of the first system to the target application configured in the second system, and reduce the development of the target application maintenance costs.

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...

Problems solved by technology

For example, the voice dialogue system SDS (Speech Dialogue System), when the first system is a Linux system, the SDS installed in the Linux system will have high development costs and difficulty in development, and the later maintenance and secondary development costs are also relatively large, and it does not support Online / remote upgrade and many other issues
