On the track of electrification, compared with the traditional OEMs that follow the trend, the new forces of the rising stars are obviously more radical, Tesla, Weilai, Xiaopeng and other companies have completed the layout on the track early, looking back at the sales list, almost these so-called new forces have achieved hegemony over the list.
But we all know that starting to move towards electric drive is what every car manufacturer is doing today, but only the real intelligent electric vehicle is the next track for the future of the car, so compared with the new forces, the traditional OEMs can determine the leading edge from the new on the track of intelligence?
In this article, we take Volkswagen's IQ.Drive intelligent driver assistance system as an example to see what kind of answer can the most representative fuel vehicle company hand over on the track of intelligence?
First, the background of the launch of Volkswagen IQ·qrive
In 2019, Volkswagen launched the IQ.Drive Intelligent Driver Assistance System, which includes all driving assistance service technologies related to driving, parking and improving vehicle safety, and is the integration of Independent Driving Assistance Functions by Volkswagen, in other words, IQ. Drive is a collection of Mass-produced autonomous driving assist functions.
The advantage of packaging these functions and unified naming is that it can enhance the memory point for consumers, and later when it comes to IQ.Drive, the first thing that pops up in the user's mind is the mass brand, and from the perspective of communication, this kind of regular and unified naming is conducive to widespread dissemination, just like Tesla's Autopilot automatic assisted driving, Xiaopeng's XPILOT, Nio Pilot automatic assisted driving...
On the other hand, after Tesla's autopilot assist system has been in the limelight (although it is friendly), the consumer market's enthusiasm for this kind of assisted driving can be described as unprecedentedly high, such as in 2109 Nielsen released a "2018 Autonomous Driving Joint Survey Report", which shows that nearly 90% of Chinese consumers are interested in self-driving cars, as if whether a car has advanced autopilot assistance functions has become an important reference for users to buy.
So in the above context, IQ. Drive was born.
Second, the historical iteration of Volkswagen IQ.Drive, which models are currently mounted
As mentioned earlier, IQ. Drive was first introduced in 2019, its first model is the 2020 Volkswagen Magotan, but we checked the relevant information, found that Volkswagen's IQ.Drive from 2019 to now, have not heard of the hardware level or software level upgrades, compared to the high frequency of hardware or software on the OTA upgrade of the new forces, the traditional OEMs on the road to intelligence is still "stable".

MPV: Volkswagen Weiran (except for the entry-level model option, the rest of the models are standard)
Third, the introduction of volkswagen IQ.Drive system
Before officially introducing Volkswagen's IQ.Drive, let's briefly introduce the composition of the automatic driving assistance system, in principle, all the automatic driving assistance systems currently on the market can be divided into three parts, namely perception - decision - execution.
Perception corresponds to sensors, such as ultrasonic radar, millimeter wave radar, lidar, etc.; decision-making corresponds to processors, such as Tesla's FSD, Mobileye EyeQ4, black sesame's Huashan No. 1 A500; execution can be understood as our operating mechanism, such as steering, braking, throttle, etc.
The whole action of autonomous driving can be analogous to a complete shot for us: first find the position of the basket through the eyes (sensors), then the brain calculates (decides) which shooting posture is needed and how much force to use, and finally sends the signal to the arm (execution) to complete the shooting action.
Of course, the automatic driving assistance system is also graded, according to the standards of the Society of Automotive Engineers (SEA), intelligent driving is divided into 6 levels, each level corresponds to a different degree of automation, as shown in the following figure:
At present, most of the vehicles on the market are in the L2 level of automatic driving, such as the Audi A8 and Mercedes-Benz S-class equipped with L3 level of automatic driving system, it is worth noting that the landing of L3 level automatic driving is not only related to technology, but also related to policy, here we will not go deeper.
Back to the Volkswagen IQ.Drive, this system is a typical L2 level of automatic driving system, from the sensor point of view, IQ.Drive has 1 front view camera (in-car mirror position), 4 panoramic cameras (one front and one rear and both side mirrors), 3 millimeter wave radar (front, left rear, right rear), 12 ultrasonic radar (left front, right front, left rear, right rear two).
(From top left to bottom right, they are: front-view monocular cameras, 4 surround view cameras, 3 millimeter-wave radars, and 12 ultrasonic radars)
At the decision-making level, we have not found which autopilot chip is used by Volkswagen IQ.Drive, some say that it is the Use of Bosch Supporting Chip, and some say that it uses Intel's Mobileye EyeQ4, but we have not seen it in the official report, so its specific performance we can only press the table first.
Based on this hardware and software conditions, Volkswagen IQ.Drive has several core functions, which we explain one by one:
The first is the Travel Assist full-speed domain driver assistance system, which is actually a collection of functions, including ACC advanced adaptive cruise system, Front Assist front anti-collision active braking system, Side Assist lane change assist system, active braking and other functions, can achieve full speed domain lateral and longitudinal control.
In terms of segmentation, the ACC Adaptive Cruise System uses a front-view camera and millimeter-wave radar to follow the vehicle in front (0-180km/h) with a Stop &Go automatic follow-up function.
LKA lane keeping is to identify the lane line through the camera, if the vehicle is detected to deviate or is about to deviate, the system applies a torque to the steering mechanism according to the speed and offset, so that the vehicle is centered.
SWA lane change assist is easy to understand, the use of two millimeter wave radar on the rear bumper to detect the rear of the car, when the speed is greater than 15km / h, the rear of the car, the rearview mirror will light up the warning light to remind the driver.
The PLA 3.0 intelligent parking system uses a fusion solution of vision sensors and ultrasonic radar, which can identify both marked and non-marking parking spaces. (If the ultrasonic radar scheme alone is used, the empty marked parking spaces cannot be recognized).)
This system also has safety assistance functions such as RTA rear traffic travel reminder, AEB, FCW, etc., which have little to do with intelligent driving, and we will not go into deep interpretation here.
3, 1 How to evaluate IQ.Drive?
After the basic functions of this system are introduced, we will make a judgment on this system from two perspectives.
The first is whether there is technological innovation? To tell the truth, Volkswagen IQ.Drive still carries the deep imprint of traditional OEMs, which will not make you feel much disappointment, and of course, it will not make you feel much surprise.
For example, in terms of assisted driving, compared with Tesla's NOA, Xiaopeng's NGP pilot auxiliary function (according to the navigation position for piloting, you can independently overtake and up and down ramps), Volkswagen IQ.Drive can only achieve basic intelligent cruise capabilities, to know that the up and down ramps, which is the real test of the real skill of the technology, need to make a series of comprehensive judgments and effective implementation of the rear traffic speed, up and down ramp path planning.
For example, in terms of automatic parking, Volkswagen IQ.Drive compared to Xiaopeng's automatic parking system gap is very large, the latter even after an OTA upgrade last year (Xmart OS 2.6.0), it has achieved VPA parking memory parking, simply put, you teach him how to park once, VPA will reproduce your parking process this time, to achieve the effect of automatic parking.
The second angle is practicality, whether it is ACC with automatic follow-up stop or some auxiliary functions, you can see that the main focus of volkswagen IQ.Drive is practicality, from this dimension can give praise.
Fourth, the public IQ. Drive market reputation
Since we borrowed a Volkswagen ID.4 CROZZ (IQ.Drive standard in Chongqing last year), let's start with subjective feelings.
The first is its opening method, very simple, as shown below, including one-button opening, distance adjustment, and speed adjustment can be operated by keys, which is more convenient. (provided the lane line is clear)
We focus on the effect after opening, first of all, the most commonly used adaptive cruise, in the high-speed section, the system performance is more eye-catching, the ability to drive in the center is stable (the curve with large curvature has not been tested), and the acceleration and deceleration rate when following the car can make the driver and occupants feel more comfortable and can greatly reduce fatigue.
In the urban section, the general scene can be very good, but at a relatively high speed through some curves with large curves IQ.Drive will automatically exit, which should be a protection mechanism, the system's ability to execute the scene is insufficient; another thing that impresses us is that iq.Drive will exit when passing through traffic light intersections without markings, but once the lane line is newly identified, it can also be automatically activated.
In a more concerned about the problem of hand off, we have not carried out a specific test, but at least can let go for more than 20 seconds, once the set time to get out of the hand after the system will have a reminder including text, progressive long sound, icons and so on.
In addition, its way of lifting the alarm can also give praise, compared to the torque sensor used by Tesla and other models, the capacitive sensor used in the Volkswagen ID.4 CROZZ (note that not all models equipped with IQ.Drive are capacitive sensors). The advantage of using a capacitive sensor solution is that you don't have to worry about the dilemma of "the direction is small and can't get out of the warning, and the direction is too large to affect the body attitude", you only need to hold the steering wheel with your hand to lift the alarm.
In addition to our subjective opinion, we also looked at some of the user's evaluations of Volkswagen IQ.Drive on the three-party website and some tires, and overall it was decent, without typical system defects and without being widely praised by users.
Fifth, volkswagen IQ.Drive competitor comparison
As the first answer handed over by the traditional fuel vehicle giant on the intelligent driving track, we are also curious about the difference between it and the new forces and friends, so we chose Tesla AutoPilot and GAC AEAN's ADiGO 3.0 to compare with it.
First of all, from the hardware side, Tesla AutoPilot (AP HW 3.0 version) has 9 cameras (1 front-view tri-eye, 4 surround view, 1 car (only Model 3 is equipped), 1 rear camera), 12 ultrasonic radar, 1 millimeter wave radar; and the ADiGO3.0 complete system includes 12 ultrasonic radar, 5 millimeter wave radar, 4 panoramic cameras, 1 in-car driver monitoring camera, 1 front-view camera (Mobileye). EyeQ4 chip solution) plus ADAS high-definition map.
Ps: The current North American version of the Model 3 became a thoroughly visual route, eliminating radar.
In terms of horizontal comparison, in terms of hardware, GAC Aean's ADiGO 3.0 advantage is more obvious, the number of millimeter wave radar is more, and the ADAS high-precision map is also the only one in the field, but they are not equipped with lidar.
(ADAS HD Map)
From the functional side, if you choose Tesla's enhanced version of the automatic assisted driving function, then you can increase the automatic assisted navigation driving (NOA), automatic assist lane change, automatic parking, intelligent summoning function, of course, the most basic ACC adaptive cruise, lane medium function Tesla's AutoPilot is also equipped GAC's ADiGO3.0 is also divided into different intelligent driving suits, namely the Smart Driving Suit (basic automatic driving ability), the Lingzun Intelligent Driving Suit (advanced automatic driving capability), and the flagship intelligent driving suit (professional-level autonomous driving capability).
We take the flagship intelligent driving suit as an example, in addition to the common adaptive cruise assist system, automatic lane change assist system, traffic congestion assist (TJA), automatic parking, it can also be based on the blessing of high-precision maps, early access to lane-level information (including vehicle current location information, speed limit, lane, lane-level path information, curvature /slope/heading/tilt, etc.), prejudging the road conditions ahead of 1 km, planning the optimal driving route in advance, which is a more obvious advantage.
So it's clear that Volkswagen IQ.Drive compares to other competitors as we've said many times before: it won't surprise you, it's decent.
Write at the end:
Overall, IQ. Drive as the public in the intelligent driving to give the answer, indeed can not make us feel amazing, whether in the hardware side or the software side or in the function side, the lack of highlights to speak of, but this is also the traditional style of the traditional OEMs, enough to use, radical this kind of thing has nothing to do with them. However, after the market has been educated by a new generation of intelligent cars led by Tesla, if the traditional OEMs have not accelerated the speed of turnaround, it is difficult to guarantee whether they can still stand in the center of the stage in the next decade of competition.
