In car mounting

In-car mounting

Detection range: 50m

Sensice 070320


In car mounting1

In-car mounting

Continuous detection with a response time of 0.1 s

Sensice 070320


In car mounting2

In-car mounting

Insensitive to ambient light and works in darkness

Sensice 070320


In car mounting3

In-car mounting

  • Display integrated with detector

Several interface options:

  • Separate display unit

  • FlexRay, CAN-bus, Ethernet, USB, RS232 or RS485

Sensice 070320


In car mounting4

In-car mounting

  • Integrated display and detector head behind windscreen

Placing the detector head:

  • Separate detector head at front of vehicle

General properties

General properties

Uses infrared spectroscopy

Sensice 070320


General properties1

General properties

  • Ice transparent to visible light

Principles of spectroscopy

  • Ice is reflective (metal like) in the MIR range

  • Ice is distinctly ”coloured” in the NIR range

Sensice 070320


General properties2

General properties

1. Dry

Four state system

2. Wet

3. Ice

4. Mix of ice and water

Sensice 070320


General properties3

General properties

1. Dry

Six state system

2. Wet

3. Clear ice

4. Snow

5. Sleet

6. Wet clear ice

Sensice 070320


General properties4

General properties

  • Ice and water thickness

  • Ice and water ratio

Six state system

  • Accepts larger layer thickness range

Sensice 070320


Failure rate

Failure rate

  • External error sources

  • Unable to separate water/ice on windscreen or in the air from water/ice on road surface

  • Staring system, detection area may leave road surface

  • Objects in line of sight, such as wipers or other cars, may interfer with detection

  • Intrinsic failure rate

Sensice 070320


Synergy effects

Synergy effects

  • Does not interfer with infrared night vision system and may share some optics with it

  • Cooperates advantageously with adaptive headlights

  • If mounted behind windscreen it may use wiper control system data

  • May beneficially use rain sensor data

Sensice 070320


Decreasing size and weight

Decreasing size and weight

  • Present volume 2.8 l, weight 2.7 kg

  • Next version volume 1.0 l, weight 0.5 kg

  • Ultimate size limit set by aperture sizes, may be made far smaller and much more lightweight

Sensice 070320


Sensice s unique detectors

Sensice’s unique detectors

Excessively expensive systems for ice detection have been around for decades

  • Sensice’s ice detectors are unique in that they are produceable at cost levels acceptable to consumers
