DENSO will jointly develop LiDAR lidar with Aeva, an American start-up company engaged in automotive sensors. The new generation of lidar can measure not only the distance and direction of general objects, but also the speed at which objects are moving. After the development is completed, pedestrians and bicycles can be detected with high precision, and the advanced automatic driving technology can be realized in difficult urban areas. After 2025, the goal is to realize practical application.
The company will develop a “frequency continuous modulation (FMCW) mode” sensor. The sensor measures the speed of movement by changing the frequency of the light, continuously irradiating the laser, and detecting that the frequency of the reflected signal changes with the distance from the object. At present, it is still technically difficult to embed this method into lidar for mass production, so it will be jointly developed with Aeva, which is good at this technology.
If it can be put into practical application, it will be possible to judge the situation of people walking behind the guardrail, for example. Details of joint research such as the start date of development are currently underway.
