Sensor configuration
In terms of sensors, WEY Macchiato is also quite willing to pay the cost, the whole car 5 millimeter wave radar, 1 long-range camera, and 4 surround view cameras, in addition to 12 ultrasonic radar. However, the official did not announce the supplier of smart driving chips.
Upgrade capabilities
Closed site comprehensive testing
Adaptive cruise
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 Bucket 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 conduct an obstacle avoidance test on Macchido, that is, we will find some dummies and fake cars to come out and see if Macchido can brake the avoidance 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
In the intelligent cockpit evaluation link, we will evaluate and score the cockpit software and hardware indicators such as the vehicle and machine system, instrument information richness, and voice interaction one by one, so that the intelligence of the vehicle cockpit can be quantified.
Screen effects
Macchiato's 14.6-inch touch screen is not only large in size, but the large-size screen design is more common in autonomous models, but what is important is that its central control screen shows a good effect. Therefore, it can get a full score of 10 points in the central control screen.
Vehicle performance
The functionality of the car machine is the main indicator to measure the degree of cockpit intelligence, a set of functions rich enough and the interaction is humanized enough to allow the driver to achieve functional control under the premise of ensuring driving safety, and increase the fun of the journey, and some even realize the seamless connection between the car and home. The performance of independent brands in terms of vehicles and machinery is often better than that of joint venture brands, and Macchiato is no exception, and the functionality and ease of use of the whole system are better.
In the process of vehicle performance, we will quantitatively score the fluency of the system, UI design, vehicle and machine function richness, instrument function richness, and extensibility.
Fluency, ease of use, and UI design
Whether the operation of the central control screen in the car is smooth and follows the hand directly affects the operation experience of the car machine, and further related to the driving safety, which is a very important performance indicator, so we will take it as a scoring item separately. In addition, whether the interface UI of the car is humanized, and whether the distribution of function pages and functional items is easy enough is also a very important criterion.
The richness of functions and experience effects of the car machine
Macchido's system has basic common functions, including online video and audio (QQ music, iQiyi video, listening companion), online map navigation (AutoNavi map), voice interaction, panoramic image (with 3D effect), driving recorder, etc., which perform well in terms of feature richness, and the experience of using these functions is relatively good.
In addition, the system also has functions such as Smart Refueling, Himalaya, iQiyi and Zhihu. However, in general, because it does not have a third-party app market, it is limited to the expansion of third-party apps.
Meter feature richness
Extensibility of in-vehicle systems
Voice interaction
Voice interaction is the most reflective aspect of the degree of cockpit intelligence, and its speech recognition accuracy, recognition speed, and high functional permissions directly affect its actual experience. At present, most of the independent brands generally do better than joint ventures and imported models in this regard, so how about Macchido's voice interaction?
Macchiato can recognize all four general functions, including navigation, air conditioning, car windows, music playback, and more. However, it does not support directional pickup, and can only recognize the driver's position voice command, and other positions cannot be recognized. In addition, each time the voice is completed, it is necessary to exit and then carry out the next voice command, and the continuous voice cannot be spoken.
Macchiato can only recognize a more accurate speech in the area of error correction speech, and has relatively high requirements for the speed of input and pronunciation accuracy. So only the sentence Navigating to the Bund recognizes success.
Macchiato voice tests semantic associations. The two sentences "I'm hot and a little cold" can be recognized. "Help me find the small Yang Sheng fry nearby" can be successfully identified, but "I want to go to eat McDonald's near Jing'an Temple" This recognition failure system, the system can not find the McDonald's near Jing'an Temple, can only find the restaurant near Jing'an Temple. In general, cross-functional compound languages fail recognition and cannot be performed.
Intelligent advanced requirements
After looking at the surface texture and functionality of the car, we further pay attention to the higher level of intelligent performance of the cockpit, such as the remote control of the vehicle, personalized memory, online updates and interesting small functions, etc. Some small functions that are more in-depth with car life are often the best embodiment of intelligence.
Macchiato supports OTA upgrades, but the frequency of OTA updates is unknown. In addition, it is equipped with rhythmic mood lights in the car, which can also be linked to remind by driver assistance with some warnings. In terms of entertainment functions, Macchido has two built-in games, which can be controlled by turning the steering wheel, and it also has a meditation space to relax people by playing music, which is still good in the intelligent advanced demand.
We have seen earlier that in the ICT-300 intelligent car evaluation standard, I don't know if you are satisfied with the performance of the Macchiato DHT-PHEV in terms of intelligent driving and intelligent cockpit. Next, we will perform acceleration, braking, elk, pile winding and noise tests on the driving control of the car itself to see how it performs.
Summary of the performance section
This test is the Macchiato PHEV version, the comprehensive power is 197kW, in the acceleration part, The Macchido motor does not have much impact, the front wheel is not skidded, the head is obvious, after 60km/h after the middle and rear section, the overall acceleration is quite stable. The brake part, thanks to the relationship between the battery, the overall braking performance is stable, the tail is not too much action, and the brake pedal feedback is not intense. In elk and pile winding tests, the dynamic performance of Macchiato's change of direction is slightly sluggish.
0-100km/h acceleration test
100-0km/h brake test
Under full braking, the performance of Macchiato can reassure us, the braking process of the body is not exaggerated tail swing, on the one hand, the relationship between the chassis and the battery, so that the Macchido lower plate is relatively solid, on the other hand, the distribution of braking force is also relatively linear, the system can distribute the braking force very well, but the suspension part is relatively soft, and the body feeling inside the cockpit is slightly exaggerated.
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
In the process of winding the pile, the left and right swings brought by the change of direction make the body somewhat unstable, but relying on the toughness of the chassis, it can also be well remedied. The intention of the front of the car to push the head at 60km/h is more obvious. Although the tail is not forced to slide, it is ok in terms of tracking, and the steering wheel feels relatively relaxed, which is a good thing for the driver.
Noise test
With the blessing of the PHEV hybrid system, the idle state Offir Macchiato's car is quite quiet, the sealant, sound insulation cotton and other parts of the cockpit are also very well supplied, and even when the engine is started, the control of noise is also excellent. However, in the case of high speed, the road noise from the wheel arch is relatively obvious, and the rest of the sound insulation performance can indeed rank first in the same level.
summary
In the end, the 2021 Macchiato DHT-PHEV ranked 15th on the list with a score of 181. Macchiato's achievements in the two major projects of intelligent driving and intelligent cockpit are relatively good, although its intelligent driving is not equipped with a wide range of high-level auxiliary functions, but in the safety and stability of the system, basically have a good play. In terms of the function of the internal cockpit, the car machine system can provide a wealth of practical functions, with the 8155 on-board chip, the actual experience is very smooth and smooth, and the resolution of the central control screen is delicate and not rough, which is commendable at this price point. However, in terms of performance, the performance is more general, and the biggest advantage is the hybrid system of PHEV.
Macchido to the current price point of view, in the field of hybrid is the middle position, but its display of intelligent part of the same level of opponents, only the new force of pure electric models, and its plug-in hybrid here can meet the needs of more users, in the limited license city can also be on the card, this is also a big advantage, the only thing to note is that Macchiato charging needs is a slow charging interface, if there is no home charging pile users, you need to consider the installation or other methods to show the advantages of Macchido.
