Development Of Digital Automobile Console And Application Of Embedded HMI System
The vehicle HMI system is the bridge between the driver and the vehicle. With the application of all LCD instruments, central control panel, HUD and other electronic products, the driver can understand the real-time information of the vehicle more intuitively.
In recent years, many high-end models at home and abroad are equipped with full LCD instrument displays that support three screen interconnection. Facing huge and complex system data, how should the embedded HMI system handle it?
With the breakthrough of the core technology of new energy vehicles and intelligent network vehicles, the development trend of automotive electronics has been irreversible. With the increase of safety regulations and information systems, the use of cockpit LCD instruments is expanding.
In recent years, with the rapid development of digital LCD instruments, fuel display Distance calculation and other functions can no longer meet the current driving scenarios, especially when new energy vehicles are driving, they need to accurately display the battery distance and the real-time operation status of the electrical drive module. This makes the car use a powerful SOC processor and highly integrated HMI when using HMI to meet the requirements of future driving schemes. The system must be available.
- The appearance of digital panel and HMI system
The appearance of the vehicle control system has greatly strengthened the communication between the driver and the vehicle, which has also promoted the birth of the navigation module and the vehicle entertainment system.
At the initial stage, the digital LCD instrument added a LCD module in the middle of the traditional pointer instrument panel to display fuel consumption, distance and various driving conditions. However, with the development of the vehicle towards electrification and networking, the highly integrated control of the vehicle becomes particularly important.
As long as the driver clicks the screen and says the command, he can control the real-time dynamic information of the vehicle. The highly integrated on-board HMI system is widely accepted.
However, the fast and convenient on-board HMI system tests the software technology integration capability of vehicle manufacturers and component enterprises. In the past, when importing embedded HMI, design engineers had to manually input 2D and 3D data into the HMI system. This usually leads to unnecessary cost and vulnerability risks It cannot meet the requirements of real-time navigation and 360 °.
- Differentiation method
The driving scenes of vehicles will be more complex in the future.
When the vehicle switches from the vehicle to the mobile terminal, the real-time data processing capacity of the vehicle is much higher than before. The design system of embedded HMI will be more complex.
At present, OpenGL ES3.0 is the standard for high complexity embedded HMI application development. Socionext, semiconductor product and service provider, new embedded HMI system solution CGI Studio.
CGI Studio is used as a design tool for embedded HMI systems. Candela 2D; engine and “engine”; cANDERA 3D; engine for 2D and 3D construction and editing; efficiency measurement and improvement; state machine integration/testing; aSIL standard feature security and complete 2D and 3D rendering engine.
The tool is widely used in various vehicle infotainment and multi screen dashboard systems in the automotive industry. At the same time, the new version of CGI Studio 3.0 tool supports OpenGL es3.0, which can help the vehicle system support navigation, vehicle status visualization, task menu structure and other high-performance 2D/3D applications.
It can also improve starting speed, reduce energy consumption and other required automotive applications. At the same time, it can break the bottleneck of complex data processing in traditional HMI systems. Using the 360 ° technology of Societext, you can achieve a perfect 3D rendering of surrounding vehicles.
At present, CGI Studio design tools are widely used in high-end models of BMW, Volvo, Ford, Toyota and other brands.
