Vehicle Detection

Running on a mono-camera the Mobileye Vehicle Detection (VD) algorithms recognize all motorized vehicles such as cars, motorcycles and trucks, in day and night time conditions (as a stand alone vision system) and was developed and tested on many tens of thousands of hours of driving from all around the world by Mobileye and global vehicle makers and accurately estimates the range to the preceding vehicle, comparably to radar based vehicle detection. Vehicle Detection provides the core detection for multiple functions –such as Forward Collision Warning & pre-crash mitigation, Headway Monitoring & Warning and from 2013 Adaptive Cruise Control (ACC) which will be launched at one of the best know luxury vehicle makers globally.

Mobileye’s first generation vision based vehicle detection is in production on a wide range of Volvo vehicles  since 2007 as a radar-vision fusion system and is also included based on a mono camera in Mobileye’s aftermarket systems providing Vehicle Detection for full speed range Forward Collision Warning and Headway Monitoring & Warning.

Today Mobileye is running multiple series development programs based on its second generation Vehicle Detection (VD2),  running on the EyeQ2 processor, both as Vision-only applications and enhanced also radar-vision fusion systems for both Warning and Collision Mitigation by Braking systems. The first launch was in 2010  on the Volvo S60  and with multiple other global vehicle makers launching from 2011 on-wards.

Based on the first generation vehicle detection using EyeQ processor and a VGA resolution imager new vehicles can be detected up to approximately 70 meters and can be tracked to beyond 100 meters in vision-only mode.

The VD2 Vehicle Detection system, based on the EyeQ2 processor, acquires new targets up to 100 meters or more with a VGA resolution imager, and tracks them beyond this. The system also detects vehicles down to zero speed for Traffic Jam Assist functionality and automatic emergency braking (AEB) or  low speed Forward Collision Warning systems . VD2 enhances vehicle detection performance in all aspects, and will enable features such as Adaptive Cruise Control to move to vision based sensing. Future use of automotive qualified high resolution imagers (to beyond 1MP) will allow new targets to be detected up to 200 meters. This will allow further enhancement of all functionality.

The second generation VD2 Vision-only Vehicle Detection system currently detects as follows:

  • New vehicles at a distance of 100 meters when using a camera with a Field Of View (Fov) of 38 deg with
    640×480 pixels.
  • The detection distance is scale-able with the resolution and FoV, so using higher resolution sensors would lead to a detection range of up to 200 meters.
  • Built in fail-safe mechanisms ensure that the system will become ‘non-available’ when conditions do not allow required performance, for example in cases of heavy fog, extreme weather or camera blockage.
  • System availability was tested in multiple production programs and proved to be rated at over 99%, and is therefore comparable to other sensing systems such as radar.
  • The Mobileye Vision-only vehicle detection provides accurate measurements of range, range rate, lateral position & rate which allows vehicle control functions to be derived. Range and range rate measurements are comparable to a radar signal, and positioning accuracy is sub-pixel.
  • Mobileye vehicle detection utilizes lane detection information and image information to provide a very accurate target selection for threat assessment and control, and for collision mitigation by maneuvering.
  • Mobileye vehicle detection provides an early detection for vehicle cut-in based on optic flow analysis to allow smoother and faster control in all applications.
