Xiaopeng 1024 Technology Day: In-depth analysis of XNGP intelligent assisted driving system

October 24th is Xiaopeng's 1024 Technology Day. Xiaopeng released its self-developed bipedal robot , integrated land-air flying car, Fuyao architecture flagship MPV model Xiaopeng X9 and other cool technologies. As an observer of smart cars, Zhineng believes that for current car companies, the intelligent driving system is particularly critical.

Among China's new car companies, Xiaopeng Motors pays particular attention to intelligent driving. "Intelligent assisted driving for all scenarios" is also the highlight of its Technology Day. This article focuses on the new intelligent assisted driving system XNGP. It is necessary not only to explore its functional characteristics and open plans in depth, but also to understand Xiaopeng's latest technological progress in the field of intelligent driving.

Part 1. Introduction to XNGP Intelligent Assisted Driving System

● XNGP: The ultimate product form of intelligent assisted driving

XNGP is Xiaopeng Motors' latest generation of intelligent assisted driving system, which inherits and develops from the XPILOT system. Its core selling point is that it can be used nationwide and can realize full-scenario intelligent assisted driving capabilities.

The “all-scenario” goal means that intelligent assisted driving services can be provided nationwide, including:

◎ "City Navigation Assisted Driving" function covering the entire city.

◎ The “ AI Designated Driver” function provides customized services for users’ commuting and high-frequency routes .

The main selling point is AI driving, which means intelligent driving helps you drive. The main features include:

◎ Available nationwide: The AI ​​chauffeur function will not be limited to any city, and users can set up AI chauffeur routes across the country.

◎ Learn once, and the whole process is seamless: Users only need to set up the route once, and it can be used after passing the cloud quality inspection.

◎ Continuous iteration: As user proficiency increases, the AI ​​driver will continue to optimize routes and habits.

● XNGP system function implementation progress and driving city opening plan

◎ September 2022: Xiaopeng releases its second-generation intelligent assisted driving system XNGP.

◎ April 2023: XNGP launches urban navigation assisted driving function in Shanghai and Shenzhen.

◎ June 2023: Expanded to Beijing and Foshan urban areas, and upgraded to version 2.0 for high-speed navigation assisted driving, providing an experience close to “zero willingness to take over”.

◎ August 2023: XNGP realizes the country's first "mapless" urban navigation assisted driving, and Beijing completes a large-scale test drive experience.

◎ September 2023: XNGP announced that it will open 50 urban navigation assisted driving mainly based on "mapless" capabilities within the year.

As of now, the XNGP system has the ability to drive in cities across the country, and the opening plan is as follows:

◎ November 2023: Expanded to 25 cities, mainly covering Beijing, Suzhou, Hangzhou, Wuxi and other cities.

◎ By the end of December: Further expanded to 50 cities, including Wuhan, Chengdu, Nanjing, Xiamen and other cities, while also opening up Fujian and core cities in central and western China.

The feature we saw this time is that the Pro and Max products are upgraded, whether there is a laser radar or not , they all use a visual system as the basis. The Pro version of Xiaopeng G6/G9/P7i will be upgraded in terms of SR perception capability, high-speed NGP capability and LCC capability.

Part 2 Technical foundation: XBrain, the ultimate architecture for all-scenario intelligent driving

From a technical perspective, it mainly involves perception, planning and the subsequent support systems.

● XNet 2.0 Deep Visual Neural Network

From a practical point of view, perception is the basic skill for smart driving. The content of this year's volume is centered around vision, which is the implementation of BEV+occupying the network.

In this regard, Xiaopeng's XNet2.0 will increase the perception range by 200% and increase the types by 11. At the same time, it integrates the industry's highest-precision pure visual occupancy network, realizing the integration of dynamic BEV, static BEV and occupancy network, and is a perception architecture with the ability to understand time and space.

This is the key to the improvement of the Pro version. From the current perspective, for Chinese car companies, the role and positioning of lidar begin to revolve around redundancy and safety, and the key to improving performance is still visual capability.

● XPlanner: Neural network-based planning and control

This part is very important. Leading companies are iterating in this field . The core issue of intelligence is to understand the world in front of us and make the right response to the endless world.

◎ Long-term planning: Analyzing continuous motivations can predict your predictions.

◎ Multi-object decision-making: Based on complete surrounding information, more comprehensive decisions can be made.

◎ Strong reasoning: When you can’t see clearly or completely, you can adapt like a human.

● Key to the next generation architecture: light map, full scene, light radar

◎ Light map: Use light map technology to achieve wider functional coverage.

◎ Full scenario: Realize full scenario connection from urban/highway connection to driving/parking connection.

◎ Light radar: Gradually reduce dependence on radar and significantly reduce the overall cost of intelligent driving.

● The key to next-generation mid- and back-end capabilities: data processing efficiency

What is being compared here is the iterative ability of the technical personnel.

◎ Improved full-stack closed-loop capabilities: Full closed-loop processing efficiency increased by 150%.

◎ Full-stack simulation capability: Every code change and model upgrade is verified through end-to-end simulation, with a cumulative simulation mileage of more than 100 million kilometers.

summary

Xpeng Motors' XNGP system is currently the leader in domestic intelligent driving technology. Among the new forces, Xpeng Motors is committed to providing users with a safer, more convenient and more comfortable driving experience, leading the development direction of future intelligent driving. Of course, the volume is still very high. We always need to track the intelligent driving iteration of Huawei . This is a company that is not afraid of anyone in terms of technology.
