As a specific embodiment, the operating System running in the in-vehicle entertainment control processor 21 is an Android System, the operating System running in the audio/video image processor 22 is an ITRON System (Industrial Real-Time Operation System center), and the operating System running in the remote control processor 23 is an osCAN System. Specifically, the vehicle-mounted entertainment control processor 21 runs an Android system, and is used for processing a human-computer interface and some non-real-time application programs according to input of a user, so that a program with high real-time performance and a non-real-time program can be separated through configuration, the Android system can carry a large number of practical application programs, the user can conveniently download, install and delete the programs, and the user can select different human-computer interfaces and styles according to the preference of the user; meanwhile, in the embodiment, the system part which has high requirement on the security level and does not allow the user to delete the system part at will is realized by the audio-video image processor 22 and the remote control processor 23. The audio/video image processor 22 operates an ITRON system, and is configured to process audio/video signals and some graphic and image information for acceleration, such as acceleration of audio signals of a radio and graphic and image information of a liquid crystal display, and provide a platform environment for processing the audio/video signals and the graphic and image information. The remote control processor 23 operates the osCAN system for processing some instructions and data information with high real-time performance and reliability, and provides a platform environment for processing the instructions and data information so as to complete communication between the CAN message information and the wireless communication module 3.
As a specific embodiment, the vehicle-mounted entertainment control processor 21, the audio/video image processor 22, and the remote control processor 23 use UART (Universal asynchronous receiver/Transmitter) for serial communication, the audio/video image processor 22, the vehicle-mounted entertainment control processor 21, and the remote control processor 23 transmit graphic image information data therebetween, and the vehicle-mounted entertainment control processor 21, and the remote control processor 23 transmit vehicle-mounted entertainment and application information data therebetween. Specifically, the vehicle-mounted entertainment control processor 21 may transmit some graphic image information data to be processed to the audio/video image processor 22 through the UART for processing, and the processed image data is transmitted back to the vehicle-mounted entertainment control processor 21 through the UART by the audio/video image processor 22; the remote control processor 23 can transmit the graphic image information data transmitted from the wireless communication module 3 to the audio/video image processor 22 through the UART for processing, and the audio/video image processor 22 transmits the processed graphic image information data back to the remote control processor 23 through the UART; the remote control processor 23 CAN transmit the vehicle-mounted entertainment information data transmitted by the wireless communication module 3 and the CAN network to the vehicle-mounted entertainment control processor 21 through the UART for processing, and the vehicle-mounted entertainment control processor 21 transmits the processed vehicle-mounted entertainment information data back to the remote control processor 23 through the UART; meanwhile, the remote control processor 23 may transmit the application program transmitted from the wireless communication module 3 to the in-vehicle entertainment control processor 21 for storage and use.
As an embodiment, the in-vehicle entertainment control processor 21 selects an i.mx53 series chip, specifically, a chip with a model number of i.mx536; the audio and video image processor 22 selects a chip with the model number of SH7269, and the remote control processor 23 selects a chip with the model number of MPC 5606. In this embodiment, the chip is the latest in the industry, and this matching is also strictly certified by the inventor of the present invention, and can overcome the defects that the chip program processing in the previous similar products is complex and the part with high real-time information of the automobile product is not separated, thereby effectively ensuring the stability of the operation of the whole system. Of course, other similar chips may be used, and are not illustrated herein, and should be known to one of ordinary skill in the art from the above description.
As a specific embodiment, the vehicle-mounted information main control module 2 further includes an operating program transferring unit (not shown in the figure), configured to transfer a program operated in each operating system to another operating system for operation. Specifically, an operating system running in the vehicle-mounted entertainment control processor 21 is an Android system, an operating system running in the audio/video image processor 22 is an ITRON system, and an operating system running in the remote control processor 23 is an osCAN system.
In a specific operation processing process, the resources of the operating systems can be transferred by the operating program transfer unit to realize mutual coordination, which is specifically represented as: 1. once one operating system is halted or software runs with problems, the running program of the operating system can be transferred to another operating system through the running program transfer unit, so that the other operating system can perform transient buffering to share the task of the operating system, and simultaneously, the reset instruction of the operating system is started immediately, and at the moment, the three operating systems are nested with each other to monitor and communicate with each other; 2. once there is more programs running on one os, other os can share some tasks, specifically: once one operating system runs more processes, so that the operating system runs at a low speed and is at potential crash risk, other operating systems share some non-essential processes of the operating system through a running program transfer unit; for example, when the ITRON system operated by the audio/video image processor 22 detects that the Android system process operated by the in-vehicle entertainment control processor 21 is more likely to cause a crash, the operating program transferring unit transfers a part of the program of the application layer to the currently operating process of the audio/video image processor 22, so as to achieve mutual coordination of system resources.
As a specific embodiment, the running program transferring unit is specifically configured to, when the number of tasks currently processed by an operating system of a real-time task during processing is greater than a predefined value, transfer a task with lower real-time performance in the currently processed tasks to another operating system for processing; when an operating system of a real-time task is halted during processing, the real-time task during processing is transferred to other operating systems for processing, and when the operating system of the real-time task during processing is recovered, the real-time task during processing is transferred back to the operating system of the real-time task during processing. Specifically, in the embodiment of the invention, the functions with high real-time performance and low non-real-time performance are processed by different MCUs separately. For example, the i.mx536 chip handles some non-real time; the MPC5606 handles highly real-time functions such as vehicle speed, water temperature, door status, etc. Generally, an MCU with high real-time performance does not allow dead halt, excessive tasks and no process to be suspended, but when the MPC5606 has multiple tasks to implement, a part of relatively unimportant processes can be shared by the MCU of i.mx536, and once the MPC5606 process recovers, the processes are immediately switched back to the MPC5606 chip for processing; in another case, when the MPC5606 crashes, all processes on the MPC are immediately switched to the i.mx5606 process, the MPC5606, which is an MCU with high real-time performance, is immediately reset, and when the system running on the MPC5606 is normal, the MPC5606 is switched back to the MPC5606, which may be referred to as inter-system buffering.
