What new features are there? Ford's new driving assistance technology

With the rapid advancement of technology, the difficulty of driving a car has become lower and lower, and the use of many automated electronic configurations has made driving a car a simple matter: the automatic transmission frees the driver's left foot, automatically Headlights, automatic wipers and other configurations allow the driver to focus on the road, while driving assistance, such as automatic parking, frees many novice drivers from the trouble of not being able to reverse the truck. So what kind of experience would it be to drive a car in the near future? Ford gave their answer.

â– Automatic driving classification

Talking about the driving experience of the future, autonomous driving is a topic that can never be avoided. Many people think that autonomous driving is when the driver enters the destination and can do anything without it. In fact, the vehicle that is not in this step can be called autonomous driving. SAE Automotive Engineers Society A rating of 0-5 was performed.

In terms of grading, the vehicle with the simplest driving assistance configuration can be said to have a certain degree of autonomous driving. Currently, the highest level of self-driving in the market is available. ability. Ford's recently demonstrated new technology, although not beyond Level 2, has many new upgrades compared to the previous ones, making it easier for drivers to drive the vehicle.

â–  Ford's driving assistance technology already realized at this stage

To figure out the upgraded black technology, let's first take a look at the driving assistance systems that are available on Ford's current production cars. Undoubtedly, the ACS low-speed driving safety system as the active brake function definitely belongs to this category, and ACC Intelligence Adaptive cruise control is a good companion on highways and part of the driver assistance system. So what else?

In addition, such configurations as the front-vehicle wide-angle camera, the lateral vehicle warning system, and the automatic high-beam sensing adjustment system that enhance driving safety are also part of the driver assistance system.

â– Ford's new technology

So what kind of black technology has Ford added to the original driver assistance system? In general, these functions can be divided into two parts: traffic congestion assistance system and V2X vehicle linkage technology.

- Traffic Congestion Assistance System

In terms of name, the traffic congestion aid system is an auxiliary driving system for solving urban congestion in big cities. The name of this system seems to be very easy to understand. In fact, it is mainly composed of two functions: with start and stop. The functional adaptive cruise system maintains an auxiliary function with the center of the lane.

From the actual test experience, this system is very natural for the performance of the stopper, the action of deceleration is not abrupt, and the comfort of the ride is well taken care of. And after the front car is completely stopped, it will also follow the rest state, and the driver's feet will never operate the brakes and the accelerator pedal.

So how do you do active cruise and maintain the center of the lane when testing the vehicle? It is necessary to look at some of the hardware installed in this car. In fact, the data is collected using only two sensors, a millimeter wave radar and a camera.

Of course, in addition to the camera and millimeter-wave radar, a display installed in the car is also obvious, but according to the engineers at the scene, in the final production car, the function of the display will now look up through the screen or HUD on the dashboard. The display system is implemented, and does not suddenly set up a screen above the center console.

- V2X car technology

Many people may not have heard of the concept of V2X. In fact, this is simplified by the English Vehicle to X. It is a technology for vehicles to communicate with surrounding vehicles and infrastructure. Through the communication between the car and the car, the car and the base station, and the base station and the base station, the vehicle can obtain a series of road traffic conditions in real time.

The V2X car-linking technology of this Ford demonstration is completed by DSRC (Special Short-Range Communication Technology) and includes two main functions: speed-based guidance and left-turn assist technology based on signal lights. Based on the signal speed of the traffic light, the vehicle receives the information when the vehicle is far away from the signal light. By the state of the signal light at this time and the time to be changed, the approximate vehicle speed without waiting for the red light is estimated according to the distance of the vehicle distance signal light. Driver.

Through communication with the signal light, the vehicle can obtain the state of the signal light at this time and the time of the next change, and then calculate the appropriate vehicle speed through the distance, thereby avoiding waiting in front of the signal light, thereby improving the fuel economy of the vehicle and Road traffic efficiency is also a good way, and all the way "unblocked" is also conducive to the driver to maintain a good mood.

In general, the new technologies exhibited by Ford have not improved the level of autonomous driving, but they can provide additional help for the driver, which not only reduces the risk, but also enhances the vehicle. Fuel economy, but the implementation of V2X train technology requires more time to complete than traffic congestion assistance systems.

â–  Solutions for a more distant future

If you think that these are the manifestations of all the latest driving assistance technologies of Ford, it is a big mistake. As a car company that promises to bring Level 4 autopilot cars to the market in 2021, Ford is in the US. And the test of the autopilot prototype is also underway in Europe, and the program has been upgraded to the second generation.

At present, although Ford's self-driving prototype has multiple cameras, it always retains the presence of at least two laser radars. This solution is significantly different from the solution of another American brand Tesla. Compared with the camera, the laser radar has fewer interference factors in function, so it is relatively more reliable. It is not widely used because its cost is still unresolved.

Editor's summary:

Some people may think that Ford's recent driver assistance technology has not been upgraded very much, but as a traditional car company, it is a normal thinking to be conservative in driving assistance technology. After all, for the new car companies, the traditional car companies The concept of "security" has more time to understand. However, the step-by-step promotion of mass production of driver assistance technology is a good state. Although several "black technologies" in this update are still in the verification stage in the Chinese market, there is no specific time to market, but I believe that with the test Upon successful completion, they will quickly meet with consumers.
