Problems solved by technology
When the AVN host does not have a built-in mobile communication module, it cannot directly connect to the network, make calls, receive text messages, etc.
When the mobile communication module is integrated in the AVN host, although both the T-Box and the AVN host can be connected to the mobile network, the cost is relatively high. Subscriber IdentityModule, customer identification module) card payment fee

Embodiment Construction
[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0037] see figure 1 In one embodiment, a mobile communication module sharing system (system for short) in a vehicle environment is provided, wherein the vehicle environment especially refers to a vehicle equipped with a T-Box (standard terminal for Internet of Vehicles) and an AVN host. The system in this embodiment includes: T-Box and AVN host. Specifically, the T-Box includes an MCU (Micro Controller Unit, microcontroller unit), a mobile communication module and a switch circuit. Among them, MCU can be integrated with CPU, RAM, ROM, counter and various I / O interfaces, which can realize various ...

The invention discloses a mobile communication module sharing system in the vehicular environment. The system comprises a T-Box and an AVN host, the T-Box comprises an MCU, a mobile communication module and a switching circuit, the MCU is connected to the control ends of the mobile communication module and the switching circuit, the MCU is connected with the AVN host so that the MCU negotiates with the AVN host about control right of the mobile communication module, the two ends of the switching circuit are connected with the mobile communication and the AVN host respectively, the switching circuit is disconnected when the MCU obtains the control right, and the switching circuit is connected when the AVN host obtains the control right. The invention discloses a mobile communication module sharing method in the vehicular environment correspondingly. According to the technical scheme, the T-Box and the AVN host can be arranged in the vehicular environment simultaneously, so that the T-Box and the AVN host can share the control right of the mobile communication module, and can be both connected to the mobile network, and functions can be diverse.
Description
technical field [0001] The invention relates to the technical field of vehicle electronics, in particular to a mobile communication module sharing system and method in a vehicle environment. Background technique [0002] The Internet of Vehicles is a system network that performs wireless communication and information exchange between vehicles, road facilities, pedestrians or the Internet, based on the intra-vehicle network, the inter-vehicle network and the mobile Internet, in accordance with agreed communication protocols and data interaction standards. . [0003] At present, cars are basically equipped with a standard terminal T-Box (Terminal-Box, also known as a car box for the Internet of Vehicles) that realizes Internet of Vehicles technology. The functions that can be realized in the information interaction of the mobile Internet include telephone, SMS (Short Message Service, short message service), vehicle control, vehicle condition query, location query, E-CALL, veh...
