In recent years, everyone has entered the field of driverless or autonomous driving. More and more highly intelligent adaptive cruises have emerged. Basically, semi-automatic driving has been achieved, but true driverless driving is still in the experimental stage because Faced with many obstacles.
The biggest obstacle is not the technical level, but external factors, including relevant regulations, roads and pedestrians, especially in our China's road conditions, can achieve unmanned driving.
It's not that it's useless to put energy into driverlessness, but the effect can't be seen right away. Instead of doing something breakthrough in other places, subverting the tradition is like the DAS line-controlled active steering technology that Infiniti is applying. And high performance hybrid system.
High performance hybrid system
In February 2011, Infiniti officially cooperated with Red Bull F1 Team as a sponsor. At the end of 2015, Infiniti ended the sponsorship relationship between the two parties, and then reached technical cooperation with Renault Racing Team, returned to Formula One, and transferred from sponsors. To the participants.
Why Renault chose Infiniti, the core reason is the hybrid technology. After the F1 rule was changed in 2014, the power unit began to use the 1.6T V6 engine + motor, and introduced the KERS (later renamed MGU-K) auxiliary system. Simply put, it is the kinetic energy recovery system, as well as the MGU-H heat recovery system.
The hybrid system on the Infiniti Q70L Hybrid is very close to the MGU-K on the Renault F1. The 3.5L naturally aspirated V6 engine provides a powerful power output, both in terms of acceleration and fuel consumption. By.
Change more than a little, magical DAS
Speaking of the Infiniti Q50's DAS line-controlled active steering, it has to talk about its predecessor. In the 1970s, this electronic control system was applied in the aerospace field and has been widely used in civil aircraft and military aircraft.
The Infiniti Q50 is the world's first mass-produced model using this technology. It has overturned the history of automotive machinery turning for more than 100 years. The structure and working principle of this system are not described here. The professor has analyzed it many times before. This time Let me talk about the experience of the professor after personal test drive, mainly the following two points.
Actively correct the direction, there is no "hands" phenomenon, when the vehicle straight into the obstacle, release the throttle, brake, hands away from the steering wheel, through the uneven obstacles, the body has been shaken violently, but the steering wheel is not moving, the vehicle Still driving straight ahead.
The system can actively correct the direction to ensure that the moment is in the direction of the steering wheel. The force of the tire will not be transmitted to the steering wheel. The so-called “hands-on†phenomenon will not appear. In reality, we only need to hold it gently. Yes, it can greatly reduce the fatigue on the non-paved road surface.
Steering precision, zero delay, in the small field track, including corners of various angles, even a left bend followed by a right bend, Q50L can easily cope, the whole process is flowing, even if the female experience of the peers are not Will be in a hurry.
The zero delay of the DAS line-controlled active steering system is very busy. Because of the electrical signal transmission, the response time is millisecond level, and the steering angle is accurate. Both of these are traditional electronic assist and hydraulic power steering. The system is unmatched.
So is it perfect?
After the trial of Infiniti's Q50L, there is still a bit of generosity in the professor's heart. The Japanese pursuit of performance is really flowing in the blood, Honda Civic, Toyota Supra, Lexus LFA, Nissan GT-R, Infiniti G37, Mazda RX- 7, Subaru Impreza STI, all over the world are performance cars.
Perhaps the most popular Japanese brands are Honda, Toyota, and Nissan, but the Japanese car companies that are truly admired are Mazda, Subaru, and Infiniti. The Mazda and Subaru models currently on sale are focused on manipulation. Although they are all electric power steering, they also have a very good steering feel and have good driving pleasure.
Infiniti now focuses on "sports". Undoubtedly, the Q50L can really feel that passion. Everything seems so perfect, but after all, there is a point that many people are entangled. Yes, DAS has turned to not " Beaten, but lost the road, the fish and bear's paw can not have both.
