A hundred years the auto industry to accelerate change
A Tier-1 supplier
Car development:
- Karl Benz (Karl Benz) invented the automobile
- Henry Ford (Henry Ford) car assembly line production
- Toyota Production System (Toyota Production System, TPS)
safety:
- Passive safety technology: Provides protection technologies and products (crash sensors, airbags, safety, etc.) when the vehicle collision.
- Active safety technology: the use of lidar, radar, cameras, sensor technology, with advanced driver assistance systems (ADAS) of certain functions to avoid a collision.
If you can get data for all vehicles wiper can have detailed weather information around the country. (Toyota)
Smart features:
- Awareness
- Memory and thinking ability
- Learning and adaptive capacity
- Behavioral decision-making capacity
Function car (Feature Car) -> Smart car (Smart Car)
Emergency braking (AEB)
adaptive cruise control (ACC)
Smart Glass:
- Lightproof rain glass: no wiper wiping the inner surface of low reflectivity, the reflected light does not meter the windscreen, so as to monitor people achieve undisturbed.
- Electric glass melting snow
- Glass image display: the transparent windshield of a partially reflective coating film coming from the projector displays the image data and, if the infrared imaging system with display, the driver can see the front of the left and right fog 2km object.
- Optical glass sunroof: using solar powered fans inside the vehicle, the battery trickle charge.
Intelligent driving scientific issues involved:
- How human driving behavior to abstract and simulation
- How to use sensors to characterize the driver's natural visual and auditory
- How to use machine intelligence to describe the driver's driving process
- How to achieve natural switching the autopilot and manually driving

Achievement of the basic technology autopilot
Heavy rain weather, millimeter-wave radar performance will be greatly decreased.
Illumination / n to the sun (such as out of the tunnel), the camera performance will decline rapidly.
Lidar is an active Ranging (the camera is passive). LIDAR afraid of the rain and fog.
Laser radar autopilot:
- Obstacle Detection
- Dynamic obstacle track
- Environmental reconstruction, such as laser-based three-dimensional reconstruction of radar and timely localization and mapping (Simultaneous Localization and Mapping, SLAM)
The ultrasonic penetration of rain and fog, and can be work in inclement weather; not sensitive to light and color, can be used to identify the difference between transparent and diffusely emissive object; not sensitive to external electromagnetic fields, can be used for electromagnetic interference environment. ranging slow, diffusion angle, the azimuth can not be measured.
DSRC, dedicated short range communication technology, IEEE 802.11p, support vehicles and vehicle (V2V) and vehicle communications and infrastructure (V2I) of.
Green's most recommended speed function, refers to the use of traffic light information is transmitted to the car driver is recommended to maintain optimal vehicle speed which can be green all the way to reduce unnecessary red brake.
GPS satellites transmit signals through the Earth's ionosphere to cause errors ± 16ns, resulting in a position error of up to 5m identified, tropospheric ± 1.5ns cause errors resulting in the position error of 0.5m.
The DGPS (Differential Global Positioning System) using a fixed known position on the real-time GPS signal is adjusted to eliminate the ranging error, and thus the position of the GPS correction signal.
Differential GPS is divided into two categories: position difference and distance difference. Distance difference divided into two categories: pseudo-range and carrier phase difference.
Technology known as carrier phase RTK (Real Time Kinematic) technology, a method for real-time processing two stations differential carrier phase measurements. I.e., the reference station is collected by the receiver carrier phase to users, the difference is evaluated solver coordinates. Carrier phase positioning accuracy can centimeter. Widely used in the art require high precision dynamic position.
Another method of positioning the car reflectance scanning the ground and recorded on the map. Driving, the sensor may scan the ground, the scanning result is compared with the map to determine the location of the car. In the study, this method very successful, the difficulty lies in the need a lot of memory to store the reflectance of the laser radar map.
Automotive Powertrain longitudinal acceleration, longitudinal deceleration braking system, a steering system move laterally
past the longitudinal direction for accelerating and braking and steering control system is decoupled transverse controller, each line has a corresponding PID controller, a recent method of control of the horizontal and vertical combined using fuzzy predictive control potential field or method.
Professor Wavren G.Bennis served as Ronald Reagan and John F. Kennedy Presidential adviser: "The future of the plant only two employees: a man and a dog man's duty is to feed the dog, the dog's job is to make people not to touch the machine."

Moravec's Paradox (Moravec's Paradox): difficult question is easy to solution, simple problem is intractable uniquely human higher-order intellectual capacity requires very little computing power, such as reasoning, chess. but the unconscious skill and intuition requires a great deal of computing power, for example, so that the computer can not have a 4 year old with - identification of a human face, raised his pencil, walk around the room, answering questions is really quite difficult.
