Next Gen Ultrasonic Sensor ICs on the rise

New Ranging Requirements for Safety and Enhanced Driving Experience

Todays Situation

Ranging became big with the use of ultrasonic sensor ICs measuring distance. Being a long term proven reliable and very efficient technology, ultrasound still is widely used, coexisting and complementing other technolgies like Radar or Lidar.


The rising market demand for more and better comfort and safety applications in cars leads to a new generation of ultrasonic ranging ICs to fulfil the future needs of Advanced Driver Assistance System (ADAS) and Autonomous Driving.


Next Gen ICs require higher accuracy as well as better short and long range performance, higher flexibility, faster communication, lower current consumption, wider supply voltage range, more diagnosis and standardization… and above all: an optimal cost-value ratio.

One for All and All for One

Fusing Ultrasound data to fill Blind Spots of Complementary Sensing Solutions

Sensor Fusion for ADAS integration

In combination with other perception modalities the ultrasonic IC can underline its advantages creating a new level confidence for autonomous driving decisions, e.g. by being insensitive to light conditions and materials.

DSI3 Standardized Fast Interface

High bandwidth and low latency - with DSI3 you can get more advanced data from the sensors with higher data rates and instantaneous data transmission, therefore earlier detection of obstacles and faster automatic braking maneuvers

Best Performance

Combining high range and accuracy. Enabling a more precise environment mapping and a more accurate short range distance detection of the vehicle in parking situations. Precise echo peak detection, high resolution signal path and signal coding allowing long range accuracy as well as cutting edge short distance detection. Enabling state of the art low speed maneuvering.

Elmos Ultrasonic Sensor - The Swiss Army Knife

Combine Flexibility and Cost Efficiency while Being Sustainable

Different Architectures

Depending on your existing architecture or future plans Elmos offers a variety of products supporting different interfaces like LIN or DSI3 as well as various architectures like daisy chain bus or point-to-point.

Direct Drive

No external transformer required and now with significantly improved short range performance meaning less costs per sensor and system.

ECU Less

Create a simple Parking System without an external ECU by simply using one sensor IC as a master. Moreover, the MASTER sensor in the chain can drive a speaker and/or display for acoustical and visual feedback

Auto Addressing

The Sensors can automatically find their position in the chain, no need for external circuits.
