Nowadays, automatic driving technology has become commonplace, the world's major manufacturers are stepping up the study of automatic driving technology, many cars are equipped with cruise function, in order to alleviate the fatigue of drivers during the driving process. The direction of research on automatic driving in different regions is not very different, such as Waymo and Tesla and other European and American companies pay more attention to the analysis of real-time road conditions around the bicycle intelligence, on this basis, on this basis, more emphasis is placed on vehicle-road collaborative automatic driving, "people-vehicle-road-cloud" synergy to improve vehicle perception.
At present, many domestic A-class cars are also equipped with automatic driving functions, among which the best are the seventh generation Elantra, the eleventh generation Civic, and the 2021 Corolla, which of these three cars is most suitable for Chinese consumers? Let's analyze it below.
(7th Generation Elantra)
Smart enough to avoid collision hazards in time
Whether it is domestic or foreign autonomous driving technology, bicycle intelligence is the foundation, through the high-precision millimeter wave radar, cameras, sensors, etc., can quickly analyze the real-time road conditions around the vehicle, and make the best on-site response.
The 7th generation of Elantra is equipped with the Hyundai SmartSense security system, with the most 23 ADAS configurations in its class, and the bicycle intelligence is enough to cope with most complex road conditions. The traffic density of domestic urban main roads is large, and the traffic flow during peak hours is slow and easy to get stuck in traffic. The seventh generation of Elantra can directly open the SCC intelligent cruise control, the car automatically maintains the following distance in the cruise state, and with the forward car forward, stop, the driver can relax the driving pressure.
In some townships, urban villages and other sections, the road planning is not perfect, pedestrians, vehicles are crowded, there may be goods piled up on the road, and the road conditions are more complicated. If you are driving a seventh-generation Elantra full of black technology, you can easily grasp the road conditions around the car. In front, rear and rear of the Elantra, millimeter wave radar and cameras are loaded, and the SVM 360° panoramic image is turned on, and the surrounding environment of the car will be projected on the central control screen, which is clear at a glance. Coupled with BCA blind zone collision assistance, FCA front collision assistance, RCCA rear cross collision assistance and other functions, always detect the car in front of and behind the car, obstacles, etc., the warning will be issued when a collision is about to occur, and the image will be projected on the dashboard, and in an emergency, it will also avoid collisions by actively correcting the driving direction, assisting braking, and full braking. Therefore, driving the Elantra, most of the complex road conditions can be easily crossed.
(7th Generation Elantra FCW Forward Collision Warning)
The 2021 Corolla also has a DRCC dynamic radar cruise control system, which can achieve adaptive cruise and drive in the process of urban driving, so that drivers can relax in a traffic jam environment. However, in the face of road conditions such as townships and urban villages, the functions of the 2021 Corolla are obviously insufficient. Corolla has a PCS pre-collision safety system, which is equipped with a camera and millimeter-wave radar in front, which can distinguish between pedestrians, vehicles, etc., and can brake in the event of a premonition collision. However, this function cannot take care of left, right and rear traffic or pedestrians, and it is easy to have blind spots in the field of vision during driving, which may lead to traffic safety accidents.
(2021 Corolla)
The Eleventh Generation Civic has certain advantages over the 2021 Corolla. Driving on the main road of the city, it is also able to follow the car in front at a low speed with the ACC active cruise control. However, when driving through township and urban village roads, it will be slightly insufficient. Civic has an FCW pre-collision warning and collision mitigation braking system, equipped with a camera and 8 millimeter wave radars, which will detect the road conditions around the car in real time and brake when a collision is likely. However, the Civic only has one front camera, even if there are many millimeter-wave radars, it cannot provide a full range of images, which is easy to produce blind spots in the field of vision, resulting in accidents.
(Eleventh Generation Civic)
Vehicle-road coordination, perceive the environment and make autonomous decisions
On the basis of bicycle intelligence, domestic automatic driving technology is biased towards autonomous driving of vehicle-road collaboration, that is, through the networking function to improve the car's environmental perception, calculation decision-making and control execution, etc., so that the automatic driving ability is further upgraded.
This is evident in the seventh generation of Elantra. The seventh generation of Elantra is equipped with the third generation of intelligent networking system, which is more familiar with the road conditions across the country than the "old drivers" who go south and north. When the driver needs to travel long distance to an unfamiliar location, he can directly open the NSCC based on navigation intelligent cruise control, the seventh generation of Elantra in the adaptive cruise process, will be based on navigation information, judge the speed limit area on the road, in the speed limit section will actively reduce the speed through, leave and then restore the initial speed.
(The 7th generation of Elantra NSCC based on navigation intelligent cruise control)
China is vast, with a large area of hills and mountains, and there are many winding roads with nine curves and eighteen bends. However, the seventh generation of Elantra can use its ultra-high automatic driving technology in these complex road conditions, so that drivers can navigate in various road conditions.
The 2021 Corolla's automatic driving technology is the DRCC dynamic radar cruise control system, but the adaptive cruise function has a great deficiency in vehicle-road coordination, which relies on the LTA lane tracking assist system to ensure that the car will not rush out of the lane, but it is impossible to judge whether there is a speed limit range in front. And when encountering curves with large curves, it is also easy to rush out of the lane and cause overturning. Therefore, car owners of Corolla still need to deal with various situations during long-distance driving, and they are obviously inferior to Elantra's self-driving technology.
The eleventh generation Civic not only has the ACC active cruise control system, but also has the TSR traffic sign intelligent identification system, which can identify the traffic signs on the road and convey the sign information to the driver, which can remind the driver not to speed on the highway, but in the absence of speed limit signs, in the strange road sections with cameras in the speed limit, you may eat a ticket. At the same time, Civic also has LXAS lane keeping assist system, RDM lane offset suppression system and LDW lane offset warning system, these three functions to ensure that the car will not rush out of the lane to a certain extent, but when encountering a curve with too large an angle, there is also a possibility of rushing out of the lane. Therefore, in terms of vehicle-road coordination, civic and Elantra are also inferior compared to it.
Compared with the above three cars, you can see the Corolla's cruise function, there is still a lot of room for improvement, Civic's cruise function is relatively leading in the domestic A-class market, but compared with the Elantra are slightly insufficient. The autonomous driving technology and a variety of ADAS configurations equipped with the seventh-generation Elantra are obviously more suitable for the domestic road environment and more in line with the needs of domestic consumers.
