And the micro control unit of the sound entertainment module is connected with and acquires the whole vehicle network message through the central gateway, and diagnoses whether the configuration is correct according to the received whole vehicle network message.
The micro control unit analyzes and identifies the message information received from the central gateway, and identifies whether the message information is matched with the network architecture type operated by the micro control unit.
If the message information is identified not to be matched with the network architecture type operated by the micro control unit, the micro control unit outputs a fault code and stores the fault code.
The invention has the advantages that: the sound system is compatible with two or more network architectures, one network architecture can be correspondingly configured according to the configuration during offline so as to adapt to the requirements of the whole vehicle, the compatibility of the sound system can be realized, the sound system can be conveniently developed once and utilized for multiple times, the sound system can be applied to different vehicle types, and the development cost and the manpower and material resources for multiple times of development and the like are reduced; different network architectures can be freely carried through offline configuration, and the method is simple and convenient. The sound system realizes two network architectures of an Autosar network and a master-slave network in the MCU, determines which network architecture is adopted by the sound system through vehicle offline configuration according to different vehicle configurations, improves efficiency and reduces the cost of manpower and material resources and the waste of resources developed for many times.
Drawings
The contents of the expressions in the various figures of the present specification and the labels in the figures are briefly described as follows:
fig. 1 is a schematic configuration diagram of an acoustic system according to the present invention.
Detailed Description
The following description of preferred embodiments of the invention will be made in further detail with reference to the accompanying drawings.
The utility model provides a sound system of many network architectures, sound system includes stereo set amusement module, the embedded little the control unit that is used for carrying on controlling of stereo set amusement module, the software encapsulation that multiple network architecture corresponds is in little the control unit, and little the control unit realizes network architecture through the software that the operation network architecture corresponds, and each kind of network architecture corresponds an information configuration code. The multi-network architecture includes at least two network architectures: an Autosar network architecture, a master-slave network architecture. The sound system is developed to package software corresponding to two network architectures inside the sound system, and one of the network architectures is configured in the form of information configuration codes through configuration equipment when the whole vehicle is off-line, so that the sound system can be compatible with various network architectures and can be applied to a plurality of vehicle types to match the network architectures corresponding to the vehicle types.
The invention overcomes the defects of the traditional development mode, provides the sound system for realizing two network architectures of the Autosar network and the master-slave network through offline configuration, can carry different network architectures and is applied to vehicle types with different configurations.
A sound system for realizing two network architectures through offline configuration has the structure that:
finished automobile offline configuration equipment: and the vehicle factory corresponds to corresponding information configuration codes in different configurations according to the configuration difference of the vehicle type, and then inputs the different information configuration codes into the whole vehicle offline configuration equipment. And then when the vehicle is off-line, the corresponding information configuration code is written into all controllers to be configured of the whole vehicle through the connection of the whole vehicle off-line configuration equipment and the vehicle.
The sound entertainment module MCU: and the micro control unit in the sound entertainment module, the software of the network architecture is packaged in the MCU, and the supported network architecture type is realized by the MCU.
A central gateway module: and forwarding the whole vehicle network message, connecting with the sound entertainment module, sending the whole vehicle network message to the sound entertainment module, receiving the sound entertainment module message, and forwarding the whole vehicle network message.
The configuration method of the sound system is realized by a configuration structure connected with the whole vehicle offline configuration equipment, the sound system and the central gateway, and specifically comprises the following steps: finished automobile offline configuration equipment: the Autosar network and the master-slave network respectively correspond to information configuration codes configured by different vehicle types and input the information configuration codes into finished vehicle offline configuration equipment; when the vehicle is off-line, the whole vehicle off-line configuration equipment is connected with the vehicle, and the information configuration code is written into the sound entertainment module MCU and is stored by the MCU. And the configured information is not modifiable and can only be changed again through offline configuration.
The sound entertainment module MCU: when a bottom software architecture is designed by the sound entertainment module MCU, an Autosar network and a master-slave network are required to be simultaneously realized in the MCU, after receiving an offline information configuration code of the whole vehicle, the sound entertainment module MCU automatically adapts to a corresponding network architecture type, and after configuration is successful, a configuration result is fed back to offline configuration equipment of the whole vehicle.
In consideration of the difference of network architectures, when the Autosar network architecture is configured to a vehicle type supporting the master-slave network architecture, the problem of whole vehicle feeding may exist, so that the audio entertainment module MCU default supports the master-slave network architecture.
A central gateway module: the module is connected with the sound entertainment module, and when the whole vehicle is successfully offline, the network message of the whole vehicle is normally forwarded.
In order to prevent the occurrence of mismatching between the sound entertainment module MCU and the whole vehicle network architecture caused by the fact that the information configuration code corresponding to the whole vehicle offline configuration or the Autosar network and the master-slave network is wrong, the sound entertainment module is additionally provided with a diagnosis mechanism: and automatically identifying whether the configured network architecture is correct or not according to the difference of the network messages forwarded by the central gateway module, and if the configured network architecture is incorrect, the sound entertainment module gives a fault code prompt.
It is clear that the specific implementation of the invention is not restricted to the above-described embodiments, but that various insubstantial modifications of the inventive process concept and technical solutions are within the scope of protection of the invention.
