Suppose that the user B needs to monitor his driving process to ensure driving safety due to factors such as age or driving experience. User a may enter the developer platform through web portal 84 and query from vehicle portal 85 for status information of the target vehicle driven by user B. The vehicle control code C is generated by the simple vehicle control module 86. The vehicle control code C may include two instructions based on the HTTP protocol format, one of which is "HTTP:// grant's. car/speed limit 60" for setting the vehicle speed. The other is "HTTP:// grandpa's car/notifier health state" and monitors the driver health status. The target vehicle is managed by the connection device connection management module 13 of the cloud 82. The vehicle control code C is transmitted to the vehicle end 83 via the SOA channel 810 of the cloud end 82. The protocol conversion module in the SOA gateway 812 of the vehicle end 83 converts the vehicle control code D into a code based on the SOME/IP protocol, for example, converts "HTTP:// grandpa's. car/speed limit ═ 60" into "SOME/IP service ID ═ 0x0001, speed limit ═ 60"; "HTTP:// grandpa's. car/notify health state" is converted into "SOME/IP service ID ═ 0x9001, health state notification". And then transmitted to the corresponding domain controller 816 through the gateway 815. The SOME/IP receiving unit in domain controller 816 receives the converted code, and then the signal conversion unit converts the converted code based on the SOME/IP protocol format into an executable signal, which is sent to the corresponding sensor ECU or actuator ECU by the signal sending unit, controls the corresponding sensor or actuator to obtain the health state of the driver, and returns to the actual state of "health" or "fast heartbeat", etc. The vehicle speed is limited to 60 by sending an executable signal to the respective sensor or actuator.
Fig. 8C is a schematic diagram of a signal processing system according to another example of the present invention. In this example, user D wishes to install an application for monitoring road conditions in the target vehicle. And when the damage is detected, reporting the damage information to the back end. The user verifies the identity information in the web portal 84 and logs into the corresponding account. Then, the state information of the target vehicle is obtained through the vehicle entrance 85, and the vehicle control code E is generated through the complex vehicle control module 87, and the vehicle control code E is used for installing the APP for detecting the road condition on the target vehicle. The vehicle control code E is further sent to the cloud via a first OTA89, sent to a third OTA of the SOA gateway 814 of the vehicle end 83 via a second OTA811 of the cloud 82, and further passed to the corresponding domain controller 816 via the gateway 815. Via a fifth OTA in domain controller 816, vehicle control code E is executed and installed, forming an application on its installed domain controller 816. And then, an executable code can be formed through the installed application program and sent to the actuator ECU, and the actuator is further executed, so that the road condition is obtained in the running process of the vehicle.
