Since Carl Benz first invented a real gasoline-powered car in 1885, automotive technology has made remarkable progress over the past century, such as anti-lock brake systems, power steering systems, wipers, electronic stability control, navigation control, etc. Wait.

According to the latest research by JD Power and Associates, 38% of car buyers see new technology as the key to buying a new car. Another survey conducted by Deloitte Consulting LLP in January 2014 showed that 61% of people who were born in the Y generation from 1982 to 2002 planned to buy high-tech cars. Masa Hasegawa, head of Deloitte Management Consulting, said that while Generation Y may not necessarily look at key metrics such as horsepower, acceleration time or engine size, they have clear needs, needs and aspirations. In addition, Gen Y consumers also need safety technology, especially the ability to reduce the risk of distracted driving.
In recent years, consumers have become increasingly eager for advanced automotive technology. These cravings have been triggered by the increase in technology applications and have become a factor in the purchase of automobiles, which has actually inspired automakers to use technology to make Innovation in differentiation. Here are some of the active security technologies currently being considered in the automotive market.
Visual sensing technology
A rear view camera that provides a view of the car while steering and reversing is now mainstream. By 2018, the United States intends to force automakers to install rearview cameras in every new car. Because of this regulation, manufacturers began rolling out new cars with rearview cameras as early as 2014.
The current new trend is the surround camera system, which uses four to five wide-angle cameras mounted on the front, rear and sides of the car to provide a 360-degree bird's eye view or front/rear split view, while some more advanced systems can even provide blind spots. Detection and parking assistance.
Back in 2005, the night vision camera was already deployed in the Mercedes S-series. This technology is now also available in the E-series. Typically, night vision cameras use long-range light-emitting diode (LED) lights to make the distance in front of the car look farther. The current night vision camera also adds pedestrian detection, which provides warning information to the driver with a heads-up display on the monitor or car windshield when the pedestrian or object approaches the vehicle.
Automatic high beam control is a new technology that allows drivers to better see the road around the curve. According to the Highway Loss Data Institute, claims for property damage liability insurance fell by 10% after using Adaptive Headlights. For automatic adjustment, the camera is mounted on the rearview mirror, detecting when the car is approaching an oncoming vehicle, and when the car is overtaking in the same direction, and turning off the high beam. It can switch between low beam and high beam, but will gradually increase or decrease the light distribution according to the approach distance of the oncoming vehicle. In addition, it can dim the high beam when making a sharp turn. After the turn is completed, if there is no oncoming vehicle approaching, re-enable the high beam headlights.
Other innovative vehicle safety features include self-adjusting navigation controls, frontal collision warning systems, automatic emergency braking, and pedestrian detection and lane departure warnings. These features use a camera or camera plus radar/laser radar to monitor roads and dangerous conditions, and sometimes even assist the driver to automatically brake to avoid a collision. Therefore, automatic emergency braking systems are becoming increasingly popular in new automobiles.
Driver monitoring is the latest application in automotive technology, using a camera to detect a sleepy driver and giving a visual or audible warning when the driver is considered to be tired or not awake. Other factors that need to be considered in the driver monitoring system include speed, road conditions, acceleration and deceleration modes.
A vision-based technology that can be applied to vehicles in the near future, including gesture recognition for human-machine interfaces, rearview/side-view mirror replacements, and airbag configurations. In gesture control, the driver can connect to a infotainment center or console without touching any buttons or displays. In the case of a rear view mirror/side view mirror alternative, the camera can be used to instantly display the rear/side condition on the in-vehicle screen. As for the airbag configuration, the camera can detect the exact position of the driver behind the steering wheel. In the event of a collision, the airbag can be precisely configured to protect the driver's vital parts.
A practical example of these new features is the Chevrolet 2015 Corvette, which has a camera for the performance data logger, is mounted in the ceiling decoration from the driver's perspective, and records the data on the SD card.
Radar sensing technology
Due to the cost reduction, more and more radar systems are used in automotive applications, especially in short-range and far-end detection and identification. Far-end radar systems are typically installed at the front of the car for front-view applications such as self-adjusting navigation controls, brake assist and collision warning. Audi's Pre Sense Front Plus is an example of a remote radar system designed to help avoid or reduce accidents at the rear of the vehicle in front of the collision, whether the vehicle in front is moving or stationary.
Short-range radar systems include blind spot detection, side-impact alarms, cross-traffic alert and lane change assistance. Chrysler's Cross Path Detection System includes visual indicators in the outside mirror. Ford's system is called Cross Traffic Alert and is an outside mirror alarm indicator.
The recent technological development push is to add wireless connectivity to vehicles. One of the advantages of this design is the combination of wireless local area network (Wi-Fi) and global positioning system (GPS) signals that allow vehicles to communicate with other vehicles (V2V) or road infrastructure (V2I).
An example of this is in a vehicle where the current car starts to brake and all subsequent vehicles receive the signal and modify the speed and distance accordingly. In the vehicle-to-infrastructure communication example, the car can become a hotspot and receive any location-based service information by radio. Connected cars can also work in conjunction with autonomous driving. The National Highway Traffic Safety Administration recently announced that they are forcing the use of certain technologies in new vehicles within 10 years, given the excellent safety effects of connected vehicles in the United States. The announcement sent a message to the manufacturer that the vehicles on the Internet represent the next phase of car safety.
Camera technology plays a key role in ADAS
So far, this article has explored many new automotive technologies. Of all these technologies, image-based systems are the most prominent. With the decline in camera cost, improved sensing performance and the development of smart visual algorithms, in the near future, at least eight to ten cameras will be replaced by rearview/circumference and night vision systems, advanced driver assistance systems (ADAS), and mirrors. Used in applications such as driving recorders and driving/vehicle interfaces.
In the near future, just like mobile phones, because of the security and convenience that cameras can provide, when consumers decide to buy a car, the camera will become a key differentiator for the car. According to industry research, by 2020, camera shipments will rise to more than 200 million units. The key growth factor for automotive camera applications will be ADAS, which was launched in 2014 by NCAP in Europe, and from 2018 onwards, the US will enforce rearview cameras. In addition, the surround camera application and parking assistance will also grow rapidly during this forecast period.
Piezoelectric Ceramic Ring
Applications: ultrasonic vibration tranducer for inkjet printer
Vibration mechanism of inkjet printer:
Generally, it is composed of piezoelectric ceramics and driving rods. By high-frequency electric excitation, piezo ceramics produce high-frequency ultrasonic vibration (above 60 kHz or higher), which is transmitted to the driving rod and generates high-frequency micro-displacement (back and forth expansion) at its front end.
Piezo ceramics components features :
1. High vibration amplitude and can withstand higher power.
2. The product has high reliability, strong maintainability, and is not easy to break down or off-line.
3. The frequency can be adjusted in a wide range, generally within the range of 10KHz.
