Automotive Ultrasonic Radar Research: as a single vehicle is expected to carry 7 units in 2025, ultrasonic radars will evolve to the second generation.
In terms of installed solutions, in 2022, 36.8%, 20.6% and 21.8% of new passenger cars in China carried 4-, 8- and 12-ultrasonic radar solutions, respectively; AVP used 12-ultrasonic radar solutions. In 2022, 28,804 vehicles with AVP were sold, rocketing by 589% on the previous year.
In China, both Audiowell Electronics and ZongMu Technology mass-produced AK2 radar in 2022; Coligen and Suzhou UDAS plan mass production in 2023; the rest companies are developing or have successfully developed AK2 radar.
Among them, the second-generation coded ultrasonic sensor of ZongMu Technology meets the German AK2 sensor appearance design standard. Through the Chirp (linear frequency modulation) coded transmission mode, the self-developed point cloud perception algorithm and probe enable the anti-noise capability of the system, with the refresh cycle in the encoding mode less than 100ms. The signal envelope helps to improve the detection of low obstacles such as ground locks and limiters. The product supports such functions as parking space monitoring, emergency braking, automatic space detection, target clustering and generation, and adaptive compensation of sensor performance parameters. The AK2 sensor was mass-produced in the second quarter of 2022, supporting customers like JAC Group, Voyah, Changan Automobile (Changan APA 7.0) and Seres.
On the one hand, ultrasonic radars have a big cost advantage in short-distance ranging, and gain ever more competitive edges. Besides the iteration of AK2 ultrasonic sensor, ultrasonic radars tend to be miniaturized and hidden. One example is AW101, a MEMS ultrasonic sensor developed by Audiowell Electronics in November 2022, mainly used for rear occupant alert (ROA), sound controlled by gesture, VR&AR and so forth. The MEMS ultrasonic sensor is a new kind of sensor that integrates piezoelectric thin films (as functional thin films) with silicon-based MEMS for miniaturization, integration, and hidden installation. The micron-level functional films and millimeter-level devices of the sensor facilitate further integration, compounding and arraying, and make it easy to design SiP and SoC devices and built circuits in.
On the other hand, ultrasonic sensors are finding application in more scenarios from parking to in-cabin monitoring. For example, Coligen is expanding the application of ultrasonic sensors in wading warning, height limit warning, low-speed F/RAEB, load warning, reverse drive assist, and AVP based on multi-sensor fusion; Suzhou UDAS is also exploring the use of ultrasonic sensors in low-speed AEB, and high-speed lane change and blind spot detection.
Besides, multi-sensor fusion represents the development trend of autonomous driving technology. At present, vehicle intelligence is undergoing `cockpit and parking integration` and `driving and parking integration`, and will see `cockpit and driving integration` soon. For them, ultrasonic radars should be integrated with different sensors to achieve different levels of functions. Examples include automated parking, enabled by “ultrasonic radars + surround view cameras” in the “cockpit and parking integrated” architecture; navigate on pilot and homezone parking pilot, enabled by “ultrasonic radars + multi-view cameras + radars” in the “driving and parking integrated` architecture; urban/end-to-end navigate on pilot, homezone parking pilot (across floors) and L2 AVP, enabled by “ultrasonic radars + multi-view cameras + radars” in the “cockpit and driving integrated` architecture.

As a single vehicle is expected to pack 7 units in 2025, ultrasonic radars will take the fast lane.
According to the statistics of the publisher, the ultrasonic radars installed in new passenger cars in China swelled by 7.4% year on year from 100.09 million units in 2021 to 107.525 million units in 2022. It is expected that the installation will exceed 140 million units by 2025. From 2021 to January 2023, there were an increasing number of ultrasonic radars installed in a single vehicle, up from 4.9 units to 5.6 units. Thanks to factors such as large-scale application of driving and parking integration, and the integration of cockpit and parking, it is expected that ultrasonic radars per vehicle will rise to 7 units in 2025, and the ultrasonic radar market will enjoy a boom.In terms of installed solutions, in 2022, 36.8%, 20.6% and 21.8% of new passenger cars in China carried 4-, 8- and 12-ultrasonic radar solutions, respectively; AVP used 12-ultrasonic radar solutions. In 2022, 28,804 vehicles with AVP were sold, rocketing by 589% on the previous year.
Ultrasonic radars evolve to the second generation - AK2 ultrasonic radar.
Amid the growth in installations and demand, ultrasonic radar technology is also advancing, and has iterated to AK2 ultrasonic radar. Compared with conventional ultrasonic radars, AK2 ultrasonic radar offers the following benefits:- Longer detection range (>5m), smaller blind spot (< 10cm).
- More echoes: DSI3 communication mode is adopted, providing the highest rate of signal propagation, up to 444kbit/s; at most 230 echoes can be supported in a sensor detection cycle.
- Anti-interference
- ASIL-B
- Waveform coding
- Multi-mode switching (for example, Longhorn AK2 supports three transmission modes: fixed frequency mode, rising delta frequency mode and falling delta frequency mode)
- Diagnosis function (for example, Bosch's sixth-generation ultrasonic radar can detect hardware deafness).
In China, both Audiowell Electronics and ZongMu Technology mass-produced AK2 radar in 2022; Coligen and Suzhou UDAS plan mass production in 2023; the rest companies are developing or have successfully developed AK2 radar.

Will ultrasonic sensors be replaced by radars in the future?
In recent years, ultrasonic sensors have faced challenged from radars. For example, in 2022, O-Film Tech introduced a solution of applying radars to low-speed autonomous driving for the purpose of space perception, and enabled the parking function using its self-developed 77Ghz radar. In 2022, TransMicrowave unveiled a short-range point cloud imaging radar, which can output 4D (X, Y, Z, V) point cloud information and enables automated parking in the 4D point cloud AVP mode, with the localization accuracy of 2cm. Tesla even announced to globally remove ultrasonic radars from Model X and Model Y since 2023. Does this mean that ultrasonic radars will be replaced or no longer needed?On the one hand, ultrasonic radars have a big cost advantage in short-distance ranging, and gain ever more competitive edges. Besides the iteration of AK2 ultrasonic sensor, ultrasonic radars tend to be miniaturized and hidden.
