Description

Vehicle-mounted domain control device and method and vehicle-mounted system

Technical Field

The invention relates to the technical field of vehicle-mounted intelligent network connection, in particular to a vehicle-mounted domain control device, a vehicle-mounted domain control method and a vehicle-mounted system.

Background

The development of intelligent cabins, intelligent driving and intelligent networking will promote the continuous increase of new functions. Meanwhile, the requirements for high computational power and large-bandwidth data transmission are more and more urgent, and the upgrading and the revolution of the electronic and electrical architecture of the whole automobile are promoted together by the driving of the concept of 'software defined automobile'; at present, each vehicle enterprise gradually starts to move from a distributed architecture with independent functions to a domain control architecture with function integration, and finally moves to a central centralized architecture with central computing and region control.

Under a distributed architecture, the software and the hardware are tightly coupled, an Original Equipment Manufacturer OEM (Original Equipment Manufacturer) is relatively dependent on suppliers, only one technical standard is mainly provided for the Tier1 in the cooperation process, and each system is provided by different suppliers, so that the whole software of the OEM becomes a mixture consisting of a plurality of independent and incompatible software systems. If the host factory wants to make a function change or add a new function, it needs to negotiate with a different vendor, and the time cost increases.

Secondly, with the increase of Electronic Control Units (ECUs), the wiring harness in the vehicle is longer and longer, which not only increases the vehicle weight and the overall cost, but also brings great trouble to the arrangement and assembly of the whole vehicle. Moreover, the computation power of the ECUs cannot be coordinated, resulting in large waste.

Under the regional architecture, the calculation force is gradually concentrated towards the center, a plurality of ECUs are combined into one regional controller, the slow regional controllers are continuously fused, and finally N regional controllers are finally formed and arranged on one controller. At the moment, the number of the ECUs can be greatly reduced, the application cost of the ECU of the whole vehicle and the wiring cost between the controllers are reduced, and the light-weight design of the whole vehicle is facilitated. Meanwhile, the sensor and the actuator are connected to the nearby area controller nearby, and hardware expansion can be achieved better. The structural form of the zone controller is easier to manage, and the automatic assembly of the wire harness is easy to realize. Currently, the mainstream functional domain architecture can be divided into five domains: the vehicle body domain, the chassis domain, the power domain, the intelligent cabin domain and the automatic driving domain. In the process of developing to a central centralized architecture, cross-domain fusion is necessary, for example, a vehicle body domain, a chassis domain and a power domain are integrated into a vehicle control domain.

In the prior art, in the development process of the above regional architecture, the matching is needed to be expensive. Not only does a large amount of software function service capability need to be built by self, but also strong software capability is needed to correspond to the System cooperation among a real-time operating System, an automobile Open System Architecture (AUTOSAR) and other key software modules at the bottom layer; another embodiment of The software capability is Over-The-Air Technology (OTA), especially Over-The-Air software upgrade FOTA (Firmware Over-The-Air) of a mobile terminal, which requires that an OEM has powerful software development capability to develop control software of an underlying executive component to be able to actually implement software defined functions or performance of an automobile.

An Electronic Control Unit (ECU) is also called a "traveling computer" or a "vehicle-mounted computer". The controller is a special microcomputer controller for the automobile in terms of application. It is similar to common computer and consists of microprocessor (CPU), memory (ROM, RAM), I/O interface, A/D converter, shaping and driving IC. The simple expression is that the ECU is the brain of the automobile.

Similarly, when the user performs man-machine interaction with the host, the sound emitted by the MIC by the user enters DSP for processing, and is sent to the Cockpit Soc after the processing, so that the host can operate according to the instruction of the user.

The 4G or 5G communication module (5) is used for sending the vehicle body data to the remote user terminal, receiving the control command of the remote user terminal and sending the control command to the Cockpit application chip Cockpit SOC (1).

Specifically, in this embodiment, the 4g or 5g communication module (5) is mainly used for realizing remote control service, some state information of the vehicle body is informed to the vehicle user through a network, and the vehicle user can also remotely acquire vehicle information and control the vehicle through a media terminal such as a mobile phone. 4G or 5G communication module (5) send the backstage with domain controller and automobile body ECU interactive information through 4G or 5G communication module (5) networking, and the user can control some functions on the car through cell-phone APP, for example, remote control door window, car interior accident warning, vehicle are stolen and are tracked. Some information of the automobile body can be sent to the backstage through 4G or 5G Module, and the user can look over the automobile body state through cell-phone APP. On the contrary, the user can send a control command to the host computer end through the cloud server by the mobile phone, so that remote control is realized. For example, open a sunroof, close a window, open an air conditioner.

In addition, after being processed by the DSP, the man-machine interaction MIC input signal is sent to a Cockpit SOC to open an application layer, and the host can realize functions according to instructions of a user, such as opening navigation and inquiring weather of today. The digital audio signal output by the Cockpit SOC needs to be converted into an analog signal through the DSP to push the power amplifier loudspeaker, so that a person can hear wonderful music.

Further, the 4G or 5G communication module is also used for being connected with a cloud server; the 4G or 5G communication module sends the vehicle body state data and the time information to a cloud server according to a certain sending interval; the user terminal acquires the vehicle body state data by accessing the cloud server, the cloud server monitors whether the user terminal sends an adjusting instruction or not, if so, control content, vehicle body state data and time information corresponding to the adjusting instruction are recorded, and a first mapping relation is established; and the cloud server is used for recommending control content corresponding to the adjustment instruction to the user according to the received vehicle body state data and the first mapping relation in the historical time period.

Further, the user terminal obtains the vehicle body state data by accessing the cloud server, and if the user does not send an adjustment instruction, the current vehicle body state is satisfied, such as the temperature in the vehicle. Once, the user sends an adjustment instruction according to the current vehicle body data, for example, a voice control instruction is sent to the user terminal to "adjust the temperature to 25 degrees" or "lower the temperature a little bit" (the user can input an instruction to lower the temperature a little bit many times until the user is satisfied with the temperature adjustment). At this time, it indicates that the vehicle interior temperature of the user is not satisfactory in the time period and needs to be adapted to the user adjustment, then the control content, the vehicle body state data, and the time information corresponding to the adjustment instruction are recorded, and the first mapping relationship is established, where the time period information includes the time period in the day, and may also include the month, the season, and the like. Therefore, based on the mapping relationship, the next time the cloud server acquires the vehicle body data, the control content corresponding to the adjustment instruction can be recommended to the current user terminal according to the currently received vehicle body state data and the first mapping relationship in the historical time period, such recommendation can be voice or text recommendation, where the historical time period is a historical time period which is matched with the season corresponding to the time period of the current time and the time period of the month in one day, for example, 12 noon in 7 months, and then the first mapping relationship in the range of 11 to 13 points in the summer time period range of 7 months is acquired. It should be noted that, if there are a plurality of first mapping relationships in the historical time period, the plurality of control contents corresponding to the plurality of mapping relationships are recommended to be executed respectively, such as temperature, humidity, and the like. And if the same control content has the first mapping relations in a plurality of historical time periods, performing fitting or averaging according to a plurality of control contents corresponding to the plurality of mapping relations to generate the final optimal control content recommendation.
