Kyocera in the Eyes of Professional Media in the Electronics Industry | Jiwei.com

In the past few decades, in-vehicle communication systems have been the most basic and safe communication method for automobiles. Now, with the development of advanced automobile driving technologies such as autonomous driving, electronic components have gradually become the main components in automobiles, and these electrified components are pursuing a better and safer driving experience.

At the just-concluded Japan Advanced Technology Exposition (CEATEC Japan), Kyocera stated that although autonomous driving technology still has a long way to go before it can be truly applied, ADAS technology has already been implemented. In the process of interacting with customers, Kyocera found that ADAS has put forward many new requirements for in-vehicle communication technology.

Kyocera believes that this demand for communication technology is mainly reflected in two aspects. First, the integration of various sensors in the car requires the car to uniformly process sensor information through high-speed ASIC. Second, the integration of external networks and vehicle information requires high-speed information communication through antennas, etc.

It can be said that for the current new type of cars, sensors are constantly collecting external data, and the amount of data that needs to be exchanged and processed is very large. If the data transmission rate is low at this time, the data processed by the car needs to be processed by the car's own processor.

However, for a car with a small overall space, it is obviously not realistic to cram a high-speed processor inside. In this case, it becomes a necessary option to transmit the car's data to the cloud for processing.

In Kyocera's view, improving the transmission speed of the car and obtaining processing results faster through advanced assisted driving systems and interconnection solutions are prerequisites for achieving a safe and comfortable driving experience.

In addition to connection technology, the automotive market also needs sensors, including LiDAR technology. Judging from the current development situation, LiDAR technology is generally considered by the industry to be one of the key technologies that can be implemented.

By collecting information about the location and surrounding environment, sensors enable cars to "sense" their surroundings. These data not only reflect changes in the vehicle's position, but also more complex information.

For example, the data collected by sensors can generate clear road condition maps. With the advancement of technology, Kyocera believes that vehicles in the future will be able to generate high-definition maps in real time. This is very important for cars. After all, road conditions are not static. Pedestrians, accidents, congestion, etc. will interfere with car driving.

In addition, sensor technology can also solve other key driving requirements. For example, LiDAR can enable self-driving cars to have a 360-degree panoramic view to ensure the safe operation of the vehicle.

In Kyocera's view, among the various functional modules of LiDAR provided by Kyocera, the transmitter uses a high heat dissipation material base plate, FC packaging, and a low inductance design based on a multi-layer structure. Moreover, Kyocera has different shapes of tube shells for both the transmitter and the receiver, and can reduce the number of parts through a ceramic cover with a built-in filter, solving technical issues such as airtight packaging.

However, it is worth noting that the industry has not yet reached a consensus on the technical path of lasers, and the technical solutions adopted by major suppliers are also different. For Kyocera, the latest solution is a solution that combines lidar and cameras.

As we all know, cars collect distance and image data through LiDAR and cameras, and combine them through software to analyze the environment around the car. At present, the common practice is to place LiDAR and cameras separately. At the exhibition, Kyocera demonstrated its latest solution that integrates LiDAR and cameras into one component.

According to Kyocera, this solution can achieve the following advantages: First, this solution integrates the originally independent cameras and lidars together, which can minimize the occupied space, which is a good thing for the space in the car where every inch of space is valuable. Second, the integrated solution can maximize the accuracy of the composite distance measurement data and image data.

With the accelerated development of automotive electronics such as advanced driver assistance systems and connected cars, the demand for automotive connectors that can be used in harsh outdoor environments that are greatly affected by wind, rain and dust is also increasing.

To meet this demand, Kyocera has also launched a new product, the "9715 Series", which, through a unique combination of shell lock structure and sealing materials, meets the high-pressure cleaning and high-temperature storage test conditions of the automotive parts wiring harness connector test method "JASO※ D616", achieving excellent waterproofness and reliability.

As for components that support the Internet of Vehicles, Kyocera also has products used in automotive headlights, corner lights, daylights and taillights. In particular, LED substrates used in headlights have a high market share in the international market.

In addition, Kyocera's semiconductor packaging substrates are widely used in high-end semiconductors or vehicle controllers in the field of communication facilities. As mentioned earlier, these information processing technologies will become the basis for supporting the Internet of Vehicles and will also have a profound impact on the realization of autonomous driving based on 5G network technology in the future.

It can be said that with the introduction of ADAS technology, the amount of information generated by automobiles is increasing, and there are new requirements for the collection and transmission of vehicle networks. In addition to traditional technologies, many technologies that have been applied in other fields may shine again in the automotive market !
