Leifeng.com: The Guangzhou Auto Show was inaugurated on November 20.
Xiaopeng Motors released the new flagship product of P7-Xiaopeng P7 Pengyi Edition. The model is available in high-performance all-wheel drive and ultra-long-life rear-wheel drive versions.After global subsidies, the national suggested retail price is 366,900-40,000 yuan.
Xiaopeng P7 Pengyi version is based on the Zhizun version of Xiaopeng P7 ultra long battery and Xiaopeng P7 high-performance all-wheel drive Zhizun version. It features a scissor door on the front door and added a unique super flashing green look. . At the same time, the model is equipped with XPILOT 3.0 automatic driving assistance system hardware, software and upgrade services, theater-level 18 speaker Dynaudio sound system, and comes with a lifetime warranty which includes motor, battery power, traffic update, VIP lifetime music 14 exclusive rights such as free and free electric tailgate.
It is worth mentioning that the Pengyi door supports customized opening and closing angles, and the user can customize the opening angle of the door.The accuracy of the opening and closing control is 5%. In addition, the Pengyi door is equipped with an obstacle avoidance radar on the left and right sides, which can automatically identify obstacles and control the movement of the door during the opening process to avoid collision between the door and obstacles. At the same time, the obstacles are removed from the rear door. It can continue to open.
At the press conference of this auto show, Xiaopeng Motors President and CEO He Xiaopeng revealed the next step of exploration in the field of autonomous driving and made substantial updates to the software and hardware systems of autonomous driving.
In terms of software architecture, Xiaopeng Motors is based on full-stack self-research and has multiple modules such as perception, behavior planning, behavior / motion prediction, map merging, etc., which can form a completely closed loop of data and algorithms and support rapid functional iteration. In terms of hardware architecture, Xiaopeng Motors will adopt solutions including high-definition cameras, millimeter wave radar, ultrasonic sensors, lidar, high-precision positioning, high-precision maps and high-performance computing platforms in the future. A total of 32 autonomous driving sensors will be used to create the maximum Strong hardware redundancy design.
This system update will bring significant improvements in four aspects.
First, the control domain is highly integrated: XPU autonomous driving intelligent control unit realizes 4 in 1, integrates intelligent driving and parking control, breaking the interaction barriers between the previous 4 domains, making the Decision making and execution and simplifying control The number of devices and wiring can reduce the weight of the system. Under the premise of adding new functions, the purchase of the car by the user can be reduced.
Second, the level of computing power has improved: the high-performance computing platform will achieve a leap in computing power from tens of trillions per second to several trillions per second, and the overall computing power will be increased by 10 times and will also reserve a large amount of There is room to increase computing power to support the implementation of higher level autonomous driving functions.
Third, the improvement of high-precision positioning: RTK terminals are upgraded from 4G to 5G. In addition to optimizing high-speed roads, the high-precision maps complement urban roads, using “IMU + GNSS + RTK (5G) + high-precision maps (high speed and city)”. The new positioning solution achieves high-precision centimeter-level positioning, low millisecond-level latency and a coverage rate of over 97.5% and is super robust, covering occlusion scenarios including high-rise buildings and underground parking.
Fourth, the improvement of perception fusion ability: the first installation of lidar on a mass-produced car will greatly improve XPeng’s ability to recognize horizontal and vertical position accuracy and spatial resolution (ultra-high resolution <0.1 ° ), and its perception ability is not affected by ambient light. Due to the high fusion degree of vision + millimeter wave radar + ultrasonic sensor + car lidar, the performance under conditions such as target detection performance, measurement resolution performance and insufficient light has been greatly improved and a more complete capacity of perception has been obtained.
According to He Xiaopeng’s speech, the first mass-produced smart car equipped with lidar will be launched in 2021. According to Xinzhijia, there are currently 5 lidar manufacturers bidding and the Hualuo house is not yet known. It is also very possible to do pre-embedding and then switch to L4 level autoguiding.
