Voice broadcast of Changsha weather

Recently, at the invitation of Changan Ford, I participated in the test drive of Ford Intelligent Vehicle Infrastructure Cooperation System (V2I). According to the official definition, Ford Intelligent Vehicle Infrastructure Cooperation System (V2I) is a system for vehicle wireless communication technology based on cellular network, which enhances the vehicle's perception of road infrastructure, helps drivers predict the traffic ahead, and thus improves the driving experience of users.

Including traffic light signal push, green wave speed, green light start reminder, red light driving warning, road information broadcasting and electronic street signs.

Traffic light signal: Have you ever seen the sight blocked while driving? For example, if there is bad weather or a large vehicle at the intersection ahead, Ford Intelligent Vehicle Infrastructure Cooperation System will help you make a prediction in advance, and remind you of the status of the traffic lights ahead through the images and sounds in the car control panel to avoid the risk of running a red light. Green light start reminder: when waiting at the intersection, you may be easily distracted and miss the green light. At this time, the car central control panel will remind you in time by voice and screen in the last few seconds of the red light countdown (users can set it by themselves). Green wave speed: how to break the curse of "eating red lights all the way" while driving? The system will combine the current state of the vehicle, your driving intention and the state of the traffic lights ahead, and remind you whether you can pass the intersection with green light through the central control panel of the vehicle with images and sounds. Help you get a better driving experience, save fuel consumption and improve overall traffic efficiency. Red light warning: Complex traffic conditions will make it more difficult for you to judge road risks. The system will make a judgment according to the state of the traffic lights ahead and the remaining time, combined with the current state of the vehicle and your driving intention. Once the system determines that you are in danger of running a red light, the central control panel of the vehicle will send out an early warning signal through sound and picture. Road information broadcast: Temporary construction often happens on urban roads, or dangerous sections caused by weather, which you can't predict in advance. This function is to broadcast speed limit signs, dangerous sections, temporary construction and other information in time to help you adjust your driving route in advance and avoid wasting time. Electronic signpost: displays traffic signs, such as speed limit information. According to Zhang Wei, the head of Ford's China car networking team, this system has been installed on six Ford models, and it is standard in all departments, covering six major cities: Wuxi, Changsha, xi 'an, Guangzhou, Wuhan and Nanjing. By 2022, the number of registered users will reach 52,000+,and the monthly activity rate will be around 40%.

This experience test drive is a new generation of Mondeo equipped with V2I system, 2.0T EcoBoost? The maximum power of the engine +8AT powertrain is 175kW, the peak torque is 376n·m, and the acceleration of 100km is 6.5s..

In terms of body, the length of the vehicle is 4935mm and the wheelbase is 2945 mm A longer wheelbase can provide more space for the car.

In terms of interior, the most eye-catching thing is that the car is equipped with an ultra-wide screen of 1. 1 meter, which extends to the passenger seat. The road information of the V2I system to be experienced this time will be displayed on it, and then it depends on the actual experience effect.

The route of this test drive is urban expressway+urban road. The whole journey is about 24 kilometers. The road conditions that day were not very rational. In view of the stop-and-go urban working conditions, the new Mondeo did not appear the phenomenon of frustration and rush. This 8AT is quite smooth in handling all kinds of acceleration and deceleration shifts, and can quickly downshift and then push the car out when it meets the scene that needs rapid acceleration.

The texture of the chassis is also very heavy, and it is handled well when pressed on the manhole cover, gravel or speed bump, which is simple and without unnecessary vibration.

As for V2I system, it can be activated as long as the vehicle-road coordination function is turned on on the locomotive.

The system will display road information on dashboard and multimedia screen, such as traffic light status information and road condition information. There will also be prompt sounds, such as red light to green light reminder, red light warning and so on.

At present, V2I system can basically synchronize with the second reading of traffic lights, which is much lower than the delay of traffic lights pushed by navigation apps. It is precisely because of the low delay that the green light start function is available, and the green light will not prompt you after a few seconds. This function is practical for users who are easily distracted by traffic lights.

After a short experience, V2I system can help users know the road ahead in advance, which is of positive significance for improving the driving experience. It can effectively improve the efficiency of crossing the street and reduce urban road congestion.

Changan Ford also said that it is currently exploring more application scenarios of the system. It will work closely with L2+ driver assistance to realize vehicle-vehicle interconnection and vehicle-object interconnection in addition to vehicle-road coordination. So as to further improve the driving safety of users.
