Automobile intelligence has become a development trend in the industry. Intelligent driving is integrating into our lives at an accelerated pace, and ADAS functions are gradually becoming standard features of various new models. In recent years, the concept of "in-one travel and parking" has also become a hot topic in the industry, and more and more manufacturers have begun to focus on the development of "one-in-one travel and parking" solutions. We can see that at this stage, the smart car industry is vigorously promoting the mass production of L2 or L2.9 autonomous driving that is close to L3. In this process, various new technologies emerge one after another, and the "one-stop-parking" solution that integrates many new technologies is highly praised by car companies

Essentially speaking, the integration of driving and parking is the connection between driving scenes and parking scenes. It needs to achieve a series of technical connections including congestion following, automatic lane changing, high-speed cruising, up and down ramps, automatic parking, etc. , the key technologies for implementation mainly include perception and positioning, decision-making and planning, control and execution, etc. The integrated parking and parking solution is the only way for ADAS to advance to high-level autonomous driving.

Common function scenarios for automatic driving

In daily urban driving, we often encounter various driving and parking scenarios. According to the driving and parking scenarios of different road sections, common smart driving functions of smart cars include:

Driving scenarios:

ACC, adaptive cruise control; ALC, automatic lane change assist; TJA, traffic jam assist; LCC lane centering; NOA, pilot assist;

Parking scene:

APA, automatic parking assist function; RPA, remote parking assist; SS, smart summon function; HPA, Memory parking function; AVP, autonomous valet parking.

The development pattern and advantages of integrated parking and parking

We can see that to achieve the above-mentioned automatic driving For driving and parking functions, most models on the market currently use traditional distributed ADAS ECUs (such as smart camera all-in-one machines, parking controllers, panoramic view controllers) and parking separate domain controllers, that is, driving domain The control and parking domain control are separated, and driving and parking call their own chips and sensors. However, as the electronic and electrical architecture of the vehicle evolves from distributed to domain-centralized, and the technology for sharing sensors and domain controllers matures, the mass production of the "integrated driving and parking" solution is being further accelerated.

Compared with the separate parking and parking solution, the integrated parking and parking solution has the following advantages:

• Sensors are shared, performance is improved
• # Improves software development efficiency, the underlying software and middleware are more versatile, and different algorithm module functions can be customized individually ;
• # Convenient for function iteration, the Xingbo integrated domain controller implements software and hardware decoupling by deploying a layered software architecture, and is equipped with 100M or even 1000M Gigabit Ethernet interface, and more computing power to support the deployment of advanced algorithm models, so it can better support OTA upgrades of functions.
• Reduce costs and increase efficiency, reuse the computing power of the controller, save the hardware cost of the controller, simplify the hardware interface of the domain controller, and reduce the wiring length. This effectively reduces the complexity of the entire vehicle and reduces the production cost of the entire controller.
