1. Automatic parking: relieve parking pressure
The automatic parking system can be regarded as one of the components of the automatic driving technology system. Large automakers such as Ford and Volvo have introduced similar technologies this year, and even ZF, a component manufacturer, has launched its parking application.
Ford's fully automated parking aid uses an ultrasonic sensor that scans the vertical and diagonal positions of the parking space at speeds of up to 18 km/h and gives the driver sufficient reaction time to avoid overtaking the parking space. The driver can control the vehicle through the remote control in or outside the vehicle. Vehicles equipped with automatic parking assistance automatically perform steering, acceleration, and braking, and automatically drive the vehicle into the parking space according to the camera and sensor-related guidance system. “Imagine you are driving into a parking lot, and there is only one last parking space. There is no room to open the door when the vehicle is parked,†Ford spokesman Scott Fosgard said at a press conference: “In this case, this (Automatic parking assistance) will help the driver to 'get out of trouble', the driver does not need to be in the car, the vehicle can automatically enter or exit the parking space 100%."
The automatic parking system introduced by other car companies basically adopts the same principle, but the sensor type and installation position are different.
However, ZF's parking applications are different. In the company's test site, there is a trailer attached to the rear of a car. In general, a "two-stage" vehicle connected to a trailer is more difficult to park when it is parked, because the front and rear sections turn in opposite directions when reversing. ZF's Smart Trailer Parking app is implemented on a smartphone, by selecting the gearbox as a forward or reverse gear and selecting the speed. After these settings are completed, the user can drag the body of the screen with his finger as he wishes, and at the same time, the trailer in the parking lot will move with the finger. The driver does not need to control the vehicle at all, and the vehicle is parked correctly in the garage.
2, smart watch: seamless connection with the car system
Mercedes-Benz launched the Pebble smart watch product at the 2014 Consumer Electronics Show and launched the matching Digital DriveStyle app.
The Pebble smart watch is equivalent to the "second display" of the driver's smartphone. This innovative wearable device unveils a new way of configuring connected cars. For example, when the driver is outside the vehicle, information such as the remaining fuel amount, the door lock condition, and the vehicle position can be obtained from the Pebble watch. When the driver is in the car, the watch display will automatically switch. Through V2V technology, the driver can be reminded of the road ahead and vibrate. In addition, users can activate Digital DriveStyle functions with different buttons according to their own preferences, such as reporting accidents, route planning, Siri voice system activation, remote multimedia control, and displaying surrounding road conditions.
3, "Driver Awareness Exploration" technology: complete the route planning before the driver enters the car
At the 2013 Los Angeles Auto Show, Toyota introduced the DAR-V, a concept-minded vehicle driver. Through the touch screen mounted on the side window of the car, the driver can get traffic, weather, appointments and other information before departure, and even mark the location of the gas station passing through the road. The remote control allows you to plan a number of scheduled tasks on the road display. Toyota said that these "daily tasks" are all planned before the driver enters the car, so the driver can focus more on the driving process.
The purpose of this technology is not only to minimize the damage at the time of the accident, but also to eliminate the possibility of accidents from the source. It is using a completely new technical approach to minimize the chances of drivers being distracted while driving.
In addition, the DAR-V system is able to distinguish between different occupants in the car and other ways to reduce the driver's distraction during driving. For example, when a child in the car is playing, the system automatically fastens the seat belt on the child. This has alleviated the pressure on parents to take care of road conditions and children's behavior while driving.
4, SMS lock system: inhibit driver distraction
At the same time as the rapid development of in-car entertainment information technology, the hidden dangers of driving distraction are gradually emerging. Sprint has been concerned about sending and receiving text messages while driving, and has introduced an innovative tool that locks SMS messages while the car is in motion. The device is inserted into the vehicle panel via the on-board OBD II diagnostic interface. It can lock the SMS and web browsing functions of the smartphone connected to the in-vehicle system. At this time, if the mobile phone receives the short message, it will be stored, and the owner can read it while parking. In addition, the owner can set the device, such as an automatic reply "I am driving now, will reply later" and other statements.
Nathan George, vice president of technology at telematics service provider Modus, said: "Related research has also shown that texting while driving is even more likely than accidents with wine racks." The company is also a Sprint "SMS lock" "The partner of device development.
The biggest advantage of this system is that it is directly plugged into the car OBD II interface, rather than a mobile phone application, so there is no need to worry about the lack of power. In addition, it will remain "normally open" and the user cannot close or disable it.
5, gesture recognition / somatosensory technology: through the various gestures in the air to perform various interior functions
Not long ago, Google announced that it has applied for a patent based auto-driving car based on gestures. This further promotes the application of autonomous vehicles. The gesture-based autopilot patent can adjust the air conditioner fan speed, air conditioning temperature, radio volume, wiper, driver's seat, and window glass position according to the driver's gesture, just like Kinect's working principle. The technology comes from the innovative company Flutter and has been acquired by Google.
The self-driving car gesture system includes at least one three-dimensional depth camera mounted on top of the car interior and a laser scanner to detect and record the driver's gesture changes at all times. The gesture sensing area of ​​this self-driving car gesture system is specific. The fan speed can be controlled by sliding up and down at the vent, and the left and right sliding can control the temperature change; gently tapping the speaker can lower the volume of the radio, and raising the finger and placing it near the ear can completely turn off the video. system. In addition, "swinging the arm at the left side of the driver's left side" can raise the driver's seat position. Flutter also said it will continue to develop a gesture control system based on the size of the gestures, the purpose of which is to achieve the functions of "pause", "next song" and "previous song" for the audio and video system. 6. Intermodal navigation: In addition to route planning, other transportation solutions are provided.
BMW and INRIX recently announced that they will be equipped with the first in-vehicle "Intermodal Navigation" system for the BMW i3 and i8 models. The new navigation system incorporates public transport options into the journey planning of the ConnectedDrive system.
The intermodal navigation system will analyze the real-time traffic conditions. When the surrounding traffic is extremely congested, the driver will be reminded to use the more convenient transportation method to reach the destination. In addition to this, the system will also indicate the bus stop closest to the current location. While providing alternative public transportation, the bus schedule is compared to the current time to provide the driver with the most time-saving solution.
In addition to being able to plan routes and offer alternative public transportation options, INRIX also offers INRIX EV services for the i3 and i8 models. This service allows the driver to know the distance between the current location and the destination, to provide an optimal route plan based on the remaining battery capacity, terrain and congestion, and to indicate the location of the charging station along the way.
The INRIX bus database contains the bus, train schedules and specific locations of the stations in 17 countries. The INRIX EV service and Lianyungang navigation service can update the database at any time via the network, including the latest charging station location and shift schedule time adjustment.
7, laser headlights: combined with matrix LED light technology, energy saving while improving safety
BMW previously announced that it will use laser headlight technology for the first time on the BMW i8. Similarly, Audi has recently released its Sport quattro laserlight concept car with laser headlight technology.
Unlike the traditional light, the laser headlights are monochromatic – they have only one wavelength of light compared to other light. This means stronger light intensity and concentrating properties. BMW claims that the laser headlights can reach a distance of up to 600 meters, which is three times that of LED lights. Due to the high efficiency of the laser, the energy required at its input is smaller, which means that the energy consumption of the vehicle electrical system is lower. Compared with the square light-emitting module in the LED lamp, the size of the light-emitting module in the laser headlight is only one percent, which provides more variability for the structural design of the headlight.
The headlight system of the Audi Sport quattro laserlight concept combines matrix LED technology with laser technology and uses a dual lamp set. The outer lamp group produces low beam through matrix LED and porous baffle, while the inner lamp group A laser is used as the high beam. The powerful laser diode (LD) is only a few microns in diameter and is significantly smaller than the LED, but the laser high beam can reach 500 meters, about twice the LED high beam, and the brightness is about three times that of the latter. .
8, automatic lane change technology: let the car change lanes, overtaking
BMW and its suppliers, Continental, are preparing to conduct large-scale road tests on a new technology, allowing vehicles to automatically change lanes without relying on the driver's manual intervention. They hope that this technology can be applied to production cars within 3-5 years.
BMW's plan foreshadows the advent of the era of "hands-free car (the driver does not need to manually control the car)." In the future, automatic lane change technology will certainly extend from a few luxury cars to the mass market. The test fleet will test automatic acceleration, deceleration and lane change technology at speeds below 130 km/h. When this technology is installed in a production car, the maximum speed allowed will be reduced, and it will generally be used in highways with poor road conditions. BMW is likely to use this technology as an upgrade to its current driver assistance package.
In addition to BMW, Audi, Mercedes-Benz and other car companies also want to add more advanced features to the current driver assistance system. The hands-free lane-changing technology enables vehicles to perform automatic lane changing and overtaking functions on unobstructed highways.
9. Pedestrian detection technology based on wireless network: “I can find the road ahead through obstaclesâ€
GM is currently developing a new pedestrian detection technology that allows drivers to automatically evade when they have not found a pedestrian or other road user. The system is based on the Wi-Fi Direct network, which does not use a shared road signal base station to relay, but uses a point-to-point wireless network mode to enable the smartphone to directly obtain information.
GM researchers have determined that Wi-Fi Direct networks can be integrated into other sensor-based target detection and driver alert systems to detect road users who also have smartphones and support Wi-Fi Direct networks for point-to-point detection. The Wi-Fi Direct system uses point-to-point communication technology to eliminate the delay in receiving information from the intermediate base station. In general, it takes 7-8 seconds for a mobile phone to obtain information from a communication base station, while peer-to-peer technology takes less than 1 second to obtain location information of another mobile phone user with the same network. Of course, all users need to keep their phones connected.
10, driver health detection technology: the car performs the corresponding function according to the driver's condition
Recent road safety surveys show that the number of deaths caused by crashes and accidents in the United States is higher than in the past; part of the reason is the sudden health of drivers.
Some automakers have proposed a solution to this problem: to develop a car health monitoring function, to diagnose the driver's health, and to send a reminder or send it to the hospital for rescue when the driver has a sudden health problem. But in the next decade, this situation is likely to change: the car will have the following functions: to diagnose the driver's health, to determine whether the driver is currently suitable for driving, to help avoid traffic accidents caused by health risks; Under the complicated driving conditions, play the soothing and cheerful music and adjust the driver's mood. The Ford S-Max concept car has this kind of intelligent function, which can diagnose the heart rate and blood sugar level of the owner.
Toyota engineer Hideki Hada revealed that another possible function of the car in the future is to monitor the driver's pulse. At present, the automotive industry is still in the experimental stage in this respect. The main idea is to read the pulse rate by the driver's hand holding the steering wheel. "In some cases, this approach does not apply, such as the driver with gloves, the driver's habits constantly changing the position of the hand, the surrounding environment continues to change.
