IEE 60-64GHzin vehicle radar technology VitaSense certified
Product Information
Specifications
- Model: VitaSense 1.5
- Frequency Range: 60-64GHz
- Operating Principle: Frequency Modulated Continuous Wave Radar (FMCW)
- Connectivity: CAN bus
Product Usage Instructions
Hardware Setup
The VitaSense sensor should be installed behind the vehicle’s headliner or in
an RF-suitable housing with the antenna facing the desired observation area
inside the vehicle.
Connection
Connect the VitaSense sensor to the vehicle’s CAN bus using the provided 4-pin
female connector. Refer to Table 1 for the pinout details.
Operation
The system transmits a low-power electromagnetic wave and detects reflections
from occupants or objects in the vehicle. It can distinguish between living
beings and inanimate objects based on how the reflections are modified by
movement.

Introduction
This document describes the RF system “VitaSense” for occupancy detection in vehicles. It covers sensors that are identified FCC ID: NSZVITA015 on the label.
Abbreviations
- FMCW Frequency Modulated Continuous Wave
- MMIC Monolithic Microwave Integrated Circuit
- CAN Controller Area Network
- RF Radio Frequency
General system description
VitaSense is a RF system for the primary use to detect persons left in vehicles but may also detect pets and other living beings. VItaSense provides this information to the vehicle’s warning systems. The VitaSense sensor is operating using the frequency modulated continuous wave radar concept (FMCW) and does not transmit any data. The VitaSense sensor is connected to a vehicle CAN bus.
Hardware
VitaSense sensor
The system transmits a frequency modulated signal, a low-power electromagnetic
wave, that is then reflected by occupants or objects in the vehicle’s
interior. As, due to their movement, occupants modify these reflected signals
differently, the system can discriminate between them and inanimate objects.
RF-Transceiver
The MMIC is a system based on FMCW radar technology and it is operating in the
60 GHz to 64 GHz band.
Data Interface
The VitaSense sensor is connected to the vehicle via the CAN bus.
Connectors
The sensor connector mates with 4-pin female connector of the vehicle. The pin
assignment of the mail connector (sensor side) is shown in Table 1 “Connector
pinout”.

System integration and use cases
The VitaSense sensor is designed to be installed hidden behind the vehicle’s
headliner or behind other RF-suitable encapsulation or housing, with the
antenna pointed at the observation area of interest in the vehicle’s interior.

FAQ (Frequently Asked Questions)
Q: What is the primary use of VitaSense?
A: VitaSense is primarily used for detecting persons left in vehicles but
can also detect pets and other living beings.
Q: How does VitaSense detect occupants?
A: VitaSense operates on the principle of Frequency Modulated Continuous
Wave Radar (FMCW) technology, transmitting signals that are reflected by
occupants or objects in the vehicle’s interior.
Q: How is the VitaSense sensor connected to the vehicle?
A : The VitaSense sensor is connected to the vehicle’s CAN bus using a
4-pin female connector with specific pin assignments as shown in Table 1.
