A reversing display method, vehicle chip and vehicle system

Abstract

The present application discloses a reversing display method, a vehicle-mounted chip, and a vehicle-mounted system. The method is used in the vehicle-mounted chip. The vehicle-mounted chip at least includes a first processor and a second processor that are connected to each other. The method includes the first processor or the second processor. The processor sends a resource allocation request to the second processor for the respective images to be displayed, the resource allocation request includes a layer resource application, and the second processor allocates at least one layer resource to the first processor and the second processor according to the layer resource application. One first layer and at least one second layer; the first processor or the second processor respectively outputs the respective images to be displayed to the corresponding first layer or second image according to the allocation status of the second processor The first layer is used to output and display the to-be-displayed image from the first processor, and the second layer is used to output and display the to-be-displayed image from the second processor. In the above manner, the present application can improve the stability and response speed of the reversing service.

Description

technical field [0001] The present application relates to the field of vehicle technology, in particular to a reversing display method, a vehicle chip and a vehicle system. Background technique [0002] As the core function of the car, the reversing service has high requirements on response speed and stability. After the user puts the reverse gear, the car should immediately enter the reversing mode, and the reversing screen should be displayed at the same time. The reversing service generally runs on the in-vehicle infotainment system (IVI, In-Vehicle Infotainment). The IVI system takes a long time to start up. During this startup time, the IVI system cannot run the reversing service. In addition, the IVI system will run at the same time. With a large number of services related to audio-visual entertainment, if the user opens more application services, the processor and memory resources will be tight. At this time, the reversing service will not have enough memory resources...

Problems solved by technology

[0002] As the core function of the car, the reversing service has high requirements for response speed and stability. After the user puts the reverse gear, the car should immediately enter the reversing mode, display the reversing screen and should run stably without any lag; the current car The reversing service generally runs on the in-vehicle infotainment system (IVI, In-Vehicle Infotainment). The IVI system takes a long time to start up. During this period of time, the IVI system cannot run the reversing service. In addition, the IVI system will run at the same time. There are a large number of services related to audio-visual entertainment. If the user opens more application services, the processor and memory resources will be tight. At this time, the reversing service will not have enough memory resources to start, and the response speed and stability of the reversing service. cannot be guaranteed

[0003] Since the user's operation behavior cannot be restricted on the IVI system, its operating environment will change from time to time, and it is impossible to completely guarantee the hardware resources required for the reversing service to run at any point in time
