Smart driving section
In the intelligent driving part, the P5 scored 108 points, which is a relatively good result. The main point of loss of P5 in this link is dummy recognition and avoidance, and all three of these tests failed. Fortunately, the P5 has played well in other projects such as automatic parking, light lane change, and autonomous access to ramps, so the board has returned a lot of points.
Sensor configuration
The perception hardware used in different versions of the P5 will be different, and the model we tested is the P version, which is equipped with complete perception hardware: 5 millimeter wave radar (front medium and long-range radar x1, angle radar x4), 9 high-perception cameras (head trinocular camera x1, fender and rearview mirror x4, rear x1, interior x1), 4 surround view cameras, 12 ultrasonic radars, and 1 set of sub-meter-level high-precision positioning units (GNSS navigation system + IMU inertial measurement unit). The smart driving chip uses the Xavier from NVIDIA, which is the same chip as the P7.
Xiaopeng P5
Compared to other models on the ICT-300 list, there is another difference, and that is that the P5 is equipped with two lidars. With the blessing of lidar, Xiaopeng can realize the navigation assistance driving function in the city in the future, and the high-speed scene experience will also be optimized.
Upgrade capabilities
The Xiaopeng P5 is based on the David platform and is the same platform as the G3i. P5 supports the OTA upgrade of the whole vehicle, the latest Xmart OS 3.1.0 will be pushed, the upgraded features include cross-floor memory parking, voice assistant small P optimization, NGP intelligent navigation assist driving experience optimization and so on. However, Xiaopeng has not yet upgraded the P5 performance and mechanical aspects of OTA.
Closed site comprehensive testing
Adaptive cruise test
Test conditions: The test car starts the adaptive cruise function at 80km/h, and sets the following distance to the second compartment. Then, during the driving process, the target vehicle will encounter non-emergency congestion in front, and then the target vehicle will slowly stop and start again after 10 seconds after stopping.
High-speed cornering is maintained
Test conditions: The test vehicle starts the adaptive cruise and lane keeping functions at 80km/h, and then the vehicle passes a curve to test the vehicle's lane-keeping ability at high speed.
Special Terrain: Pile Identification
Test conditions: The test vehicle opens all driving assistance functions at a speed of 30km/h to test whether there will be warnings or avoidance actions when the vehicle encounters the pile bucket group.
Pedestrian scene recognition and avoidance
The above three items are tests of the driving assistance function of the vehicle, and as a smart car, in addition to helping the driver "drive", it must also help the driver avoid possible traffic accidents. So next we will carry out the obstacle avoidance test on the Xiaopeng P5, that is, we will find some dummies and fake cars to come out and see if the P5 can brake and avoid in time.
Fixed dummy identification and avoidance
Test conditions: a child dummy is fixed in the middle of the zebra crossing, the test car starts the adaptive cruise at a speed of 50km/h and all the driving assistance functions pass to see if the test car can stop in time in front of the dummy.
Mobile dummy identification and avoidance
Test conditions: An adult dummy will pass the zebra crossing at a speed of 5km/h, and then the test car will turn on the adaptive cruise at a speed of 40km/h and all the driving assistance functions will pass to see if the test car can stop in time in front of the dummy.
Mobile dummy ghost probe identification and evasion
Test conditions: The child dummy crosses the zebra crossing at a speed of 5km/h, and the test vehicle starts cruising at 40km/h and passes all driving assistance functions. Unlike the mobile dummy crossing test, the ghost probe will add a fixed obstacle car to the front side of the zebra crossing, which will form an emergency situation of "ghost probe" when the test vehicle is close to the zebra crossing.
Tunnel fixed obstacle vehicle identification and avoidance
Test conditions: A fixed target vehicle model is placed in the simulated tunnel, and the test vehicle starts cruising at a speed of 50knm/h and all driving assistance functions are close to see if the final test vehicle can avoid the target vehicle. The project of the tunnel fixed target vehicle is actually a simulation of the situation that when entering the tunnel during daily driving, there is a sudden stop in the tunnel. In this case, because the driver has a large contrast in light inside and outside the tunnel, there is a high probability that the car stopped in the tunnel will not be found in time, which will eventually lead to a rear-end accident. If the vehicle's driver assistance system can avoid this type of obstacle car, it will give the occupants an extra guarantee.
Vehicle emergency congestion identification and avoidance
Test conditions: The target vehicle will be more urgent at a speed of 20km/h, while the test vehicle will cruise at a speed of 50km/h.
Automatic parking
Summary of tests
Open road testing
In the actual high-speed road test, the P5 can turn on the high-speed NGP navigation assist driving function, automatic lane change, autonomous access to ramp, automatic speed adjustment and so on can be successfully realized. In terms of automatic lane change, after encountering a slow car in front, the system will actively turn on the lights to change lanes, and it will automatically accelerate during lane changes. In terms of entering and exiting the ramp, the ramp will become the most side lane at about 2 kilometers, and the speed will be controlled at about 40 km/h after entering the ramp. And after the ramp is merged into the main road, the speed limit will be adjusted, although the speed of the car crossing the ramp is slower, but it is good to be successful.
Of course, although the function can be completed, in the case of large traffic, the efficiency of NGP will be lower than that of human driving, because the probability of multi-system lane changes will be reduced.
As for other aspects, the NGP performance of P5 is relatively similar to that of P7, and this performance is also expected by us, because P5 without lidar is not enabled, the software and hardware are no different from P7, and naturally there will be no sense of experience beyond P7.
In addition, everyone is most concerned about the lidar, P5 is currently listed in the XPILOT 3.0 navigation assisted driving function listed without enabling lidar, until the second half of 2022 pushed XPILOT 3.5 will be enabled, and XPILOT 3.5 also supports high-speed and urban navigation assisted driving, before our colleagues also experienced the City NGP of Xiaopeng P5, interested friends can click the following figure to watch the video:
After testing intelligent driving, we entered the link of smart cockpit. In the era of smart cars, the smart cockpit is actually the most easily perceived part of the lift, so the good or bad of the smart cockpit can be said to directly affect the intelligent feeling of a car. Xiaopeng P5 we are confident in this regard, because we have already felt the performance of Xmart OS on P7 and G3i, and believe that the P5 of the same software will not be left behind.
Looking at the results first, xiaopeng P5 scored 83 points in the smart cockpit part, which is a relatively good performance. P5 uses Xmart OS software, in the car-machine interaction, functional applications and voice control can be satisfactory, the five major sections in the intelligent cockpit, P5 has not appeared too lagging behind, which also shows that the comprehensive P5 car machine is relatively good.
Screen effects
Vehicle performance
In today's electronic era, the importance of the on-board system for the vehicle is self-evident, a set of functions-rich, interactive experience of the car machine system not only makes the daily use of the car more comfortable, but also improve the safety of driving. In terms of vehicle performance, we quantitatively score the fluency of the system, UI design, feature richness, instrument function richness, and scalability.
Fluency, ease of use, and UI design
The versatility of the car
Meter feature richness
Extensibility of in-vehicle systems
Voice interaction
Voice interaction is an important embodiment of the degree of cockpit intelligence, but also a major publicity point for many intelligent cars today, as for the recognition ability of the speech system, recognition speed, and the functions involved in the control, there are many differences between different models on the market.
In this part of the test, we will be divided into conventional function implementation, recognition speed, error correction ability, semantic association ability and other aspects of evaluation, to see the P5 equipped with this set of Xmart OS system voice interaction intelligence.
Xiaopeng P5 voice interaction system supports navigation, music, air conditioning and window control functions, and the overall recognition and response speed performance is excellent.
In the speech correction link, P5 faces non-standard Mandarin, and after repeated tests, the system can recognize the "navigate to the Bund" one sentence, and the other two sentences cannot be correctly recognized. This performance is the same as the performance of the G3i, probably because the car engine system uses a set of identification engines.
In the semantic association link, Xiaopeng P5 can recognize and execute the fuzzy instructions for air conditioning and navigation, but the sentence "Help me find the nearby Xiaoyang Sheng fry" is recognized and does not perform the search. In the cross-function order, Xiaopeng P5 gave us a surprise, "turn down the temperature and open the passenger window" this sentence can recognize and correctly execute the two instructions, "turn down the temperature and navigate to Jing'an Temple" is to identify that it is not executed. Although only one sentence of the two cross-functional orders can be recognized and executed, this is already better than most of the models in the list, and the speech interaction system of the general model cannot perform the cross-functional language orders.
Intelligent advanced requirements
After looking at the surface texture and internal functions of the car machine, we put forward higher level requirements for the smart cockpit, involving some functions that are more in-depth with the car life, such as remote control of the vehicle, personalized memory, online updates and interesting small functions.
Earlier, we have seen the performance of P5 in intelligent driving and intelligent cockpit in the ICT-300 intelligent car evaluation standard. Next, the car itself will be controlled by acceleration, braking, elk, piling and noise tests to see how it performs.
Also put the results first, the P5 is not the main performance of the model, so the performance in the performance part is more conventional. The score of 23 points is consistent with the G3i, which is also related to the fact that the two are built on the same platform.
0-100km/h acceleration test
P5 in the acceleration of the full electric door to give people a very stable feeling, without the tram of the very exaggerated push back feeling, which is consistent with the positioning of P5 and mechanical parameters performance. In the end, the 7.74 seconds is really not fast, and if you want to pursue speed, you will have to consider P7 at the next level.
100-0km/h brake test
Full braking, 38.6 meters this result is good, but the nod phenomenon during the braking process is more obvious, and the body in the brake stop within 3 seconds there is a significant up and down shaking appears, which has a certain relationship with the soft suspension and the weight of the battery pack.
Elk test
The purpose of the elk test is to test the vehicle's ability to avoid danger, test the vehicle suspension and dynamic adjustment skills. In our elk test, the default electronic system state is turned on (not manually turned off ESP, etc.) to restore the daily car situation as much as possible.
Winding test
Noise test
Come to the interior noise test, the test is the vehicle's sound insulation ability. In addition to testing the in-car noise values under the traditional idle, 60km/h cruise, 90km/h cruising and 120km/h cruising states, the noise outside the car is also recorded and compared with the in-car noise values in the idle state.
summary
In the end, Xiaopeng P5 scored 214 points, ranking 8th in the ICT-300 list. This achievement is naturally good, and behind this achievement, it relies on Xiaopeng's driving assistance and cockpit system. From Xiaopeng P5, we see that the new forces define the car with software and function as the core, popularize the same set of software through all models, and then set up some special functional scenes in combination with the characteristics of the model itself, so as to quickly enhance the product competitiveness of the new car.
However, P5 also has the "bad habits" of the new forces, that is, some configurations that should have been there, which are not equipped at the factory and require subsequent OTA upgrades to unlock. Like the P5's pedestrian AEB, these features should be ready to use at the factory, rather than waiting to be pushed by an OTA. (Photo/Text: Du Qingwei)
