Detailed Description
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The inventor of the present application has found through research that, in the conventional technology, an on-board system on a vehicle is updated according to the life cycle of the vehicle. If the on-board system is updated according to the life cycle of the vehicle, the on-board system is likely to be unable to run the latest intelligent system and/or intelligent application after being used for a period of time, such as 2-3 years, due to insufficient computing and/or storage capabilities of the on-board system. And if the whole vehicle-mounted system is updated once in a period of time, the cost is higher.
The inventor of the present application finds in research that, on one hand, in the conventional technology, a hardware portion corresponding to a vehicle-mounted system is implemented by one board card, which results in that the whole board card needs to be updated if the vehicle-mounted system needs to be updated. However, some functions in the vehicle-mounted system, such as the part of the vehicle-mounted system that communicates with the sensor device on the vehicle, need not be updated very frequently, and may be updated according to the lifecycle of the vehicle, since the sensor device on the vehicle is updated according to the lifecycle of the vehicle. On the other hand, considering that the updating speed of some devices in the vehicle-mounted system is relatively high, especially the device providing the computing function and the device providing the storage function have relatively large performance changes basically in about 2-3 years.
In view of this, the embodiment of the present application provides an on-board system, which includes a system board and a computing board, and the system board and the electronic board are connected through a connection component. The system board is used for communicating with the sensor device on the vehicle, so that the update period of the system board can be consistent with the life cycle of the vehicle. After the system board acquires the data to be processed from the sensor device, the data to be processed can be sent to the computing board through the connecting part, the data to be processed is calculated by the computing board, and the calculation result is returned to the system board through the connecting part. The computing board can be updated according to actual requirements, and therefore when computing capacity or storage capacity and the like required by the intelligent system and/or the intelligent application running on the vehicle-mounted system need to be improved, the computing board can be updated, so that the intelligent system and/or the intelligent application can normally run on the vehicle-mounted system, and the problems in the prior art are solved. Moreover, only updating the computing board does not update the system board, and the cost is within a controllable range.
Various non-limiting embodiments of the present application are described in detail below with reference to the accompanying drawings.

In an implementation manner of the embodiment of the present application, in consideration of a certain difference possibly existing between interfaces of units on a computing board, in order to ensure uniformity of interfaces between the computing board and a system board, an interface of a voltage conversion unit, which is a specific power management interface on the computing board, may be prevented from being exposed to the connection component as much as possible, the voltage conversion unit may not be directly connected to the power supply unit, but is connected to the power supply unit by another chip, for example, an housekeeping management unit, which is further connected to the voltage conversion unit, the housekeeping management unit receives a first voltage output by the power supply unit through the connection component, transmits the first voltage to the voltage conversion unit, and converts the first voltage into a power supply voltage of a component on the computing board by the voltage conversion unit.
In an example of the embodiment of the present application, the aforementioned Housekeeping unit may be embodied as a Housekeeping Controller (HKC), and the embodiment of the present application does not specifically limit a specific model of the HKC. As an example, the HKC can be, for example, an ST Microeletronics SPC58family series single chip microcomputer. This HKC, in addition to delivering the first voltage to the power management unit, may also be responsible for the processing of other traffic by the HKC.
