Description

Technical Field

[0001] The present invention relates to the field of vehicle light and shadow technology, and in particular to a whole-vehicle light and shadow control system. Background Art

[0002] At present, the automotive atmosphere lights in the industry mainly have the following problems:

[0003] 1. It can only display simple lighting effects of breathing and flowing water, with monotonous style changes and high repetition;

[0004] 2. According to the design requirements and cost requirements of the automotive ambient light system in the previous industry, the styles of the ambient light interpretation are fixed and cannot be changed after leaving the factory. The user's sense of freshness will gradually disappear over time;

[0005] 3. Users cannot customize the style of the ambient light;

[0006] 4. The current automotive technology development route is a distributed electronic and electrical architecture. As the demand and requirements for ambient lighting become higher and higher, the architecture of the ambient lighting system becomes more complex. This not only increases the difficulty of system design and development, but may also affect the stability and reliability of the system. For example, the architecture of the automotive ambient lighting on the market is that the BCM (body control system) sends instructions to the RGB Control Unit to control the turning on and off of all lights in the car. Some complex ambient lighting effects require the RGB Control Unit to send instructions to the ALCM (Ambient Light Control Module). The ALCM controls the ambient lighting components in different spatial positions to achieve the linkage of the ambient lighting style, achieving more precise lighting effects and synchronization of lights. However, the complexity of the distributed electronic and electrical architecture control system increases, thereby increasing the possibility of system failure. The application of distributed electronic and electrical architecture will lead to an increase in the cost of the ambient lighting system. In addition, complex system design and development may also lead to an increase in labor costs. With the development of automotive electronic systems, different automobile manufacturers may adopt different control methods and standards. This may lead to compatibility issues between different models of ambient lighting systems, increasing the difficulty of system integration and maintenance.

[0007] 5. The technical development route of automobiles is to develop in the direction of domain control. Domain control is to divide the whole vehicle into several domains such as powertrain, smart cockpit, and autonomous driving according to the functions of automotive electronic components, and use multi-core CPU / GPU chips with stronger processing power to relatively centrally control each domain, that is, DCU (automotive domain controller DCU (Domain Control Unit)) will replace the current distributed electronic and electrical architecture. And the control source of the ambient light will be transferred from BMC to DA (in-vehicle entertainment information system), and provide more appropriate, more accurate and smooth ambient light styles according to the current user's driving scenario or entertainment scenario. Thanks to the domain control architecture, the ambient light system can remove some intermediate control components and reduce the overall development cost. The application of domain control technology may bring new security risks. For example, if the domain controller fails, it may affect the normal operation of the ambient light system and may even affect the operation of other key systems. In addition, due to the increased interaction between the ambient light system and other systems, new network security risks may also be brought.

[0008] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0011] A whole vehicle light and shadow control system, comprising:

[0012] The in-vehicle infotainment module is used to input the required ambient light style through the specified interface;

The in-vehicle infotainment system controls the ambient light component in the same way to achieve vehicle domain control.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The core solution of the whole-vehicle light and shadow control system provided by the present invention is to realize automobile domain control, and release the control rights of the lamp beads of the atmosphere light component to the on-board infotainment system through the agreed interface, so as to realize the requirements of automobile domain control; the whole-vehicle light and shadow control system realizes the decoupling of the interpretation of the atmosphere light lighting effect style, and is responsible for receiving data from the on-board infotainment system and distributing the data to the atmosphere light component, and the atmosphere light component executes the data distributed by the whole-vehicle light and shadow control system; the whole-vehicle light and shadow control system supports a maximum of 30fps lighting effect style interpretation, and utilizes the powerful video analysis capability of the on-board infotainment system to analyze the lighting effect style video that the user wants to interpret, and convert it into data that can be recognized by the whole-vehicle light and shadow control system, so as to realize real-time interpretation of the atmosphere light lighting effect style that the user wants.

[0018] The vehicle's light and shadow control system is designed according to the concept of automotive domain control. The control rights of the lamp beads of the ambient light components are released to the automotive domain controller through the interface. The ambient lighting style of the vehicle's light and shadow control system is controlled by the on-board infotainment system, and the components do not need to save fixed styles.
