Automotive Radar Sensors

Automotive In-Cabin Monitoring (ACAM)

A smart contactless sensor is applied for detection and classification of living beings in an automotive cabin. Various safety-related and comfort functions, as well as a new system solution for autonomous vehicles of the future have been incorporated.

The basic idea is to have a hardware system driven by different signal processing software packages covering sets of different in-cabin applications.

Following applications are addressed:

  • Child Presence Detection (CPD) – an unattended baby in a parked car is detected

Pursuant to Euro NCAP, in order to obtain the highest safety marking, all new passenger vehicles shall have the Child Presence Detection Function installed by 2022.

  • Seat Occupancy Sensing and Seatbelt Reminder (SBR)

Number of occupied seats by human beings in a vehicle is calculated, independently if an adult, kid or baby sits in the vehicle. The system is able to differentiate an object, i.e. a piece of luggage from a human on the seat.

  • Life Presence Detection – real-time life presence monitoring

This application includes detection of pets, or any other living beings, including adults in a vehicle’s cabin, luggage compartment or the “third seat” areas of vans.

  • Respiration Rate Monitoring

The respiratory rate of the specific passenger on the specific seat is calculated. If needed, heart rate frequency can also be detected. This information may be used for gathering health care data. In case of permanent monitoring and statistical evaluation, safety-related events, and driver’s behavior status specific to autonomous driving could be calculated as well.

  • Classification – Adult vs Child (age 0Y-6Y)

A sensor detects specific seats with a person on it, specifying whether this person is an adult or a kid. No complex pressure sensors integrated into the seat are required. Recommendations for Airbag set-ups are provided.

  • Safety Belt Lock Monitoring

A sensor detects if an occupied seat is locked or not. No electricity is rear seats is needed.

  • Driver Fatigue Sensor

The sensor is observing a driver’s vital signs statistical behavior, and by combining vital signs with additional information, such as duration of continuous driving and driving dynamics, probability of fatigue has been calculated, driving under influence, or losing the capability to drive.

  • Emotion Sensor

The sensor is observing a driver’s vital signs statistical behavior. It is mapping vital signs information on the personality related behavior lookup table. Probability of anxiety, excitation, calmness, drowsiness is calculated. This allows the vehicle to respond by actions such as changing comfort features in the cabin. This may include adaptation of dashboard colors, lighting conditions, temperature, music as well as audio loudness depending on the passenger mood.

Industrial Radar Sensors

RADAR IoT (RIOT)

Radar sensors are extremely versatile in their application. Our Radar IoT devices bring powerful features to smart devices of future. Whenever reliable and robust motion sensing in a small, easy to integrate and cost-effective package is needed, Novelic’s mm-wave radar IoT sensors are the perfect fit.

Following applications are addressed:

  • Lighting Solutions

The NRM302 is specifically engineered for the use in lighting systems. The design goal of this sensor is to provide a competitive advantage over traditional PIR sensors. High motion detection sensitivity achievable with radar sensors ensures that your lighting solution keeps track of a user’s presence even in scenarios when the user is sitting still and PIR sensors are unable to pick up any motion at all.

In addition to its advanced detection performance, this sensor is capable of recognizing distance to any detected objects. It is thus possible to precisely limit the detection range to the area of interest. Often it can be very tricky to install and angle an outdoor PIR sensor in a way that keeps it away from reacting to any passer-by outside of your property and still maintain a satisfactory detection performance in areas you need it. With our hassle-free distance limiting feature, fiddling with the sensor orientation now belongs to the past.

Radars neither need an optical path like PIR and cameras nor a contact to the surrounding air like ultrasonic sensors which is why they can be integrated behind a wide range of non-conductive materials such as plastic, wood and even ceramics. There is no need for cut-outs or lenses that disrupt the appearance and texture of your product’s design.

  • Security Systems

Radar is a very robust technology for outdoor use. It can work in harsh weather conditions such as rain and snowfall while still maintaining a reliable detection of any intruders trying to enter your protected area. Its high sensitivity makes it impossible to sneak by. Any single movement no matter how slow, can be detected.

Since this technology can be completely concealed and does not require any additional visible or IR floodlights it can be installed safely and unobtrusively.

Radar is completely independent of ambient and object temperatures. Its main advantage is the fact that detection sensitivity will not degrade even when outside temperatures rise to a human body’s temperature and PIRs cannot detect any motion. Masking the heat signature of a person to prevent being detected is impossible with this technology.

  • Automatic Sliding Doors

Unlike the other two applications, radar is already commonly used as the main activation technology for automatic sliding doors. However, nowadays most of the radars used in this application are simple motion sensors. More sophisticated models may even be able to detect a movement direction of objects but are completely incapable of any distance measurements.

In order to prevent any unnecessary activation of automatic door systems, it is important to avoid triggering on any cross traffic or people standing the vicinity of the door only without any intention to enter. With the precise distance measurement capability of the NRM302 it is possible to define the exact trigger zone in front of the door and distinguish people lingering close to the door from those approaching it.

Knowing distance and velocity of everything in the detection area allows to calculate the time of arrival of any person approaching the door to further improve cross traffic cancelation and improve user experience by ensuring the door is activated as soon as necessary in order to prevent people from having to change their pace and wait for the door to open.

Zone Radar Monitoring (ZORM)

Radar as a detection technology is the best choice in rough environments when high reliability is a must. This sensor solution is equipped with all necessary RF, hardware and software components required for stand-alone operation. The application software runs directly on the sensor and provides for all relevant application data without the need for any additional radar signal processing on the user side.

Following applications are addressed:

  • Robotics

Sensor is installed on an industrial robot and observes surroundings. It adds a sense to the robot to detect people and objects that are in its vicinity and might be a collision hazard. By knowing exactly where people and other objects are, robots do not need to be fenced off and can collaborate with humans for a more productive and safe work environment.

  • Safety Zones

In industrial manufacturing people work around large machines that have accessible moving parts likely or pose safety hazards to the workforce. Often, view into and around machines is obstructed. Zone monitoring radar sensors are machine operators’ eyes to look around corners and detect people entering safety zones. The radar detection can be used to notify the machine operator or to stop machines automatically if a person enters a restricted zone.

  • Security Systems

Reliable motion detection and a very low false alarm rates are key to a trustworthy security system. The sensor can be installed instead of or in addition to security cameras. It will penetrate through fog and rain and even work in completely dark environments without any need for IR illumination. The high availability in any weather condition makes it ideal technology to help security personnel focus on real threats and not to be distracted by false alarms.
