  1. Truck Safety Applications for Cost-Efficient Laser Scanner Sensors Malte Ahrholdt, Volvo Group, Sweden

  2. Overview • Introduction • Relevant Detection Regions • Truck Applications • Start Inhibit • Right-turn Assistance • ACC Stop & Go • Cost-efficient laser scanner development in MiniFaros • Vehicle Integration • Status & Conclusions ITS World Congress 2012

  3. MiniFaros Project Low-cost miniature Laserscanner for environment perception • Focused Research Project: ICT – 2009.6.1, # 248123 • Duration: 36 Months (Jan 2010 – Dec 2012) • Coordinator: Kay Fuerstenberg (SICK AG) • Budget: 4.8 M€ (3.2 M€ EC funding) • Consortium: ITS World Congress 2012

  4. Introduction • Volvo are participating in MiniFaros from the perspective of a heavy vehicle OEM: • How can cost-efficient laser scanners be used on heavy vehicles? • What Advanced Driver Assistance System (ADAS) functions can be developed? • Setting requirements on the sensors to fulfil these functions • Building a vehicle to demonstrate a set of useful ADAS functions (Volvo FH12 rigid) ITS World Congress 2012

  5. Relevant Detection Regions • Detection regions for heavy vehicle applications are: • Forward Detection Area • Long range, relatively narrow FOV • Safety and comfort functions: e.g. • Adaptive Cruise Control • Lane Departure Warning • Automatic Emergency Braking • Vicinity Detection Area • Short range, wide FOV • Safety functions: visibility for the driver is very poor ITS World Congress 2012

  6. Truck Applications Three ADAS target functions for Volvo demonstrator truck: Start inhibit Right-turn assistance ACC stop & go ITS World Congress 2012

  7. Truck Applications – Start Inhibit • Start Inhibit function details: • Safety function • Driver has very poor visibility in front of truck • 10% of all VRU accidents with heavy vehicles occur as frontal collision from 0 km/h • Prevent the vehicle from accelerating when avulnerable road user (VRU) is in the immediate path of the vehicle • Requirements of the sensor for start inhibit: • Detection range 0-5m • 180º FOV in front • Reliable detection of VRU (pedestrians, cyclists etc.) • Host vehicle 0km/h ITS World Congress 2012

  8. Truck Applications – Right Turn • Right-Turn Assistance function details: • Safety function • Driver has very poor visibility at the front and right of truck • 30% of all pedestrian accidents with heavy vehicles occur when truck is making right hand manoeuvres • System warns the driver when a collision is likely • Requirements of the sensor for right-turn assistance: • Detection range -5 to 15m forward,0-5m on side • ~250º FOV • Reliably detection of VRU (pedestrians, cyclists etc.)in cluttered, urban environments • Host vehicle speed, slow to medium ITS World Congress 2012

  9. Truck Applications – ACC Stop & Go • ACC with Stop & Go function details: • Comfort function • ACC already exists in production • Requirements of the sensor for ACC Stop & Go : • Detection range 0-80m • Relatively wide FOV • Reliably detect vehicles • Host vehicle speed to 90km/h, target to 90km/h ITS World Congress 2012

  10. Sensor designconcepts a biaxial system with separate receiver and sender lens and a coaxial system based on one single lens ITS World Congress 2012

  11. Prototype ITS World Congress 2012

  12. VehicleIntegration 250º FOV ITS World Congress 2012

  13. Status and Conclusions • First sensor prototype was delayed, received in October 2012 • Initial sensor tests performed • Application integration on-going • Cost efficient sensor with wide field of view can offer many advantages for commercial vehicle ADAS functions: • Reduce the need for many sensors to fulfil functions • Good accuracy and potential object classification • With the planned vehicle mounting and sensor specs, 3 valuable ADAS functions are implemented on a Volvo truck: • Start inhibit • Right-turn assistance • ACC stop & go ITS World Congress 2012
