Background

The central challenge of ADAS is to replicate the ability of a human driver to interpret visual data. The human eye is a bioengineering miracle – and our brain not only combines the two different signals from our left and right eyes, but also interprets the result faster and more accurately than all but the most powerful computers. ADAS engineers strive to replicate this through digital sensing and processing. A dilemma quickly arises, however, as getting better data usually requires more and more sensors – until the vehicle’s microprocessors simply cannot integrate all the data in real time.

Kyocera is developing new solutions that apply convergence, miniaturization, and solid-state conversion to multifunctional sensors that can simplify ADAS design and help contain processing requirements. The company’s latest ADAS innovations represent an integration of technologies into advanced materials, components, devices and communications infrastructure.

Cameras and LiDAR

Since cameras and LiDAR each offer unique advantages, they are often used in combination. Cameras are ideal for detecting the color and shape of an object; LiDAR excels at measuring distance and creating very precise three-dimensional images. However, digital imaging of two units that do not share the same optical axis has a deviation error known as parallax. A computer can theoretically integrate two channels of data to correct the parallax error, but the resulting time lag creates a barrier to any application that requires very precise, real-time information, such as driving.

World’s First Camera-LiDAR Fusion Sensor Incorporates Proprietary Kyocera Technology

Characteristics

1. Camera and LiDAR: two devices in one unit 1

Kyocera’s patented Camera-LiDAR Fusion sensor combines a camera with LiDAR to provide highly accurate images in real time. Since both devices use the same lens, the camera and LiDAR signals have identical optical axes, resulting in high-resolution 3D images without parallax deviation.

2. Data without delay: Ideal for automotive use

With just one unit 1, the process of integrating camera and LiDAR data is greatly simplified, enabling fast and accurate object detection without delay to improve driving safety.

3. Durability is maximized by Kyocera ceramic technology

While other LiDAR systems have used a motor to continuously spin a mirror while scanning an image, mechanical assemblies introduce reliability issues amid the shocks and vibrations of normal driving. Kyocera has developed a semiconductor solution using a Micro-Electromechanical System (MEMS) mirror that eliminates conventional rotary assembly, based on advanced ceramic technology developed by Kyocera as a world leader in ceramic semiconductor package.

Development status

Kyocera’s Camera-LiDAR fusion sensor is currently under development and its release is expected by March 2025. It is expected to be used both in vehicles and in various other fields, such as construction, robotics, industrial equipment and security systems capable of recognizing people and objects.

1 Kyocera has filed intellectual property patents incorporating camera and LiDAR technology in five regions. Patents have already been filed in Japan and the United States, including in the United States 10,838,044, with patents pending in Europe, China and South Korea.

Millimeter wave radar

Radar is based on the same concept as LiDAR, but uses radio waves instead of light to measure distance, speed, and angle by calculating the time and frequency differences in the return signal. A key feature of the radar is that its accuracy is not easily degraded by weather conditions or backlighting.

Since millimeter wave radar is widely used in ADAS applications, many vehicle platforms integrate multiple radar sensors for various purposes. For example, individual radar sensors are typically installed for front view, blind spots, collision detection, park assist, exit detection and / or fully automatic parking, among others. As a result, the complexity of the ADAS system and the processing requirements keep increasing.

Kyocera Multifunctional Millimeter Wave Radar Module

Kyocera has developed multifunctional millimeter wave radar technology that can detect multiple objects at different distances and directions using a single millimeter wave sensor.

Characteristics

1. Miniaturization carried out using the 79 GHz band

Using the 79 GHz band, Kyocera managed to miniaturize the volume and area of ​​the antenna, resulting in a compact module form factor measuring only 48 × 59 × 21mm.

2. Very precise distance measurement

The accuracy of the range of millimeter wave radar depends on the bandwidth of the frequencies used. Kyocera’s multi-functional millimeter wave radar module takes full advantage of its high bandwidth – 77 GHz to 81 GHz, with a width of 4 GHz. As a result, it can provide very precise distance measurements, accurate to just 5cm (about 2 inches).

3. Multi-function speed camera support

Kyocera’s technology supports multi-function radar applications, which can independently set multiple detection modes with different detection distances and directions. This unique feature brings new value to millimeter wave radar through beamforming technology. In general, conventional millimeter wave radars detect the same point at regular intervals (eg, 50 ms, 100 ms, etc.). In contrast, Kyocera’s high-speed switching allows simultaneous detection of multiple zones. As a result, a single module can simultaneously provide blind spot detection, free space detection and / or other detection functions.

4. Reduced cost and complexity of the system

Using Kyocera’s millimeter wave technology, functions currently requiring multiple sensors can be integrated via high-speed switching into a single radar module. This helps reduce the total number of radar sensors, helping to reduce costs and simplify design. In principle, modules offering three different detection functions could replace a system of 12 single-function sensors with a future system of only four multifunctional modules.

Kyocera’s two technologies for multifunctional millimeter wave radar

Kyocera’s millimeter wave radar innovation takes advantage of the “adaptive array” antenna technology the company has developed for commercial telecommunications network infrastructure. This beamforming transmission and reception technology enables fast and accurate estimation of the reception angle of multiple signals and arbitrary adjustment of transmission and reception timing. As a result, mutual interference with other millimeter wave radar signals can be reduced or eliminated.

In addition, Kyocera’s high frequency organic substrate materials help ensure low loss and high efficiency in waveguides (feedlines) and microstrip antennas. By tailoring millimeter wave antennas to specific applications, several functions can be integrated effectively and efficiently – a key feature of the multifunctional millimeter wave radar.

State of development

Kyocera is currently developing a multi-functional millimeter wave radar module that uses 60 GHz radar in addition to conventional 77 GHz and 79 GHz radars. Since the 60 GHz band can be used both indoors and in vehicles, it is expected to have a variety of applications. In addition to ADAS, this module will be able to detect children left in cars, analyze waveforms and vibration spectra of industrial machines, or detect the heartbeat and breathing of a sleeping patient. in a medical establishment or a care establishment. An availability calendar will be announced.
