About AVL's testing program

AVL becomes the first company to undertake a complete testing tour of Great Britain with an autonomous vehicle developed here in the UK. 

Rapidly growing demand for Connected and Autonomous Vehicles (CAV) and Advanced Driver Assistance Systems (ADAS) is changing the landscape of the automotive industry. The UK is establishing itself at the forefront of CAV and ADAS development.

Along with UK government support, many companies are investing heavily, with higher level Autonomous Vehicles and their sophisticated functions expected to be introduced to the market in the coming years. AVL is at the forefront of developing skills and innovative solutions for Autonomous Vehicles at its technology centres across the UK.

For several years already, the company has been developing ADAS and highly autonomous systems installed into demonstration vehicles. The company’s latest demonstration vehicle features AVL’s Highway Pilot function, enabling hands-free and feet-free driving. This solution has been undergoing extensive testing on selected public roads and test tracks in the West Midlands over the last six months. To verify the robustness of this Highway Pilot function in further real-world conditions, considering further variations in weather, light, traffic and road layout, AVL is expanding the locations used for the public road trials, by undertaking an extensive test programme covering most of the major road network in England, Scotland and Wales. The data gathered will increase the industry’s understanding of the challenges facing Autonomous Vehicles. At all times, a qualified test driver and engineer are present to take over control.

The latest AVL demonstration vehicle also represents an Integrated Open Development Platform, which allows other companies to evaluate technologies and gain insight into development challenges.


AVL is the world's largest independent company for development, simulation and testing of passenger cars, trucks and large engines with more than 8,600 employees worldwide.

Testing in such a large variety of environments and for prolonged periods enables a thorough evaluation of system performance and capability. This enables complete familiarity with system characteristics which provides firm ground for investigation and diagnosis of system drawbacks. The collected data will be processed and combined with the experience gained to plan and develop improvements to the current system.
The experience gained also clearly demonstrates the sensitivities of operation of a level 3 autonomous feature allowing valid and efficient testing in future.


Tour Diary

Coventry: Start of the tour

 

15th February, 2018

Our crew, Peter and Matthew, completed the final system checks from AVL’s vehicle centre in Coventry and set off for the first leg of the UK tour! What happened today:

  • Completed system check and test run
  • The first two hours on the road
  • Conditions Encountered: Bright Sunshine, Heavy Traffic
  • Successful Testing: Lane Centering and Adaptive Cruise Control


First Update: On the way to Glasgow

20th February, 2018

Our robustness drive through the beautiful landscape leads us further north to Scotland. We encounter typical winter driving conditions and are able to collect valuable data about the performance of our detection systems and response of our vehicle control.

The weather and road conditions: Light to mid rain, significant spray on dual carriageway, further north thick fog
Testing:
  • Favorable conditions with LC (Lane Centring) operational allows speed variation
  • LC operational during longitudinal gradients
  • LC operational in off camber highway scenarios
  • ACC (Adaptive Cruise Control) operational on complex single carriageway
  • Operation at reduced cruise speed through construction areas using line detection to perceive cat’s eyes to good effect
Performance & findings:
  • Spray causes significant challenges to detection; data gathering here will aid further development and refinement
  • These roads present a greater variation in road camber, which has highlighted short-comings in the current calibration – The learning here will be used to develop improvements to system performance which will compensate for these effects
  • Despite some challenging conditions, the performance and availability of the feature was nonetheless encouraging

Our testing crew is happy with the collected data and looks forward to our next leg of road to Manchester!




Second update: From Glasgow through the Lake District to Manchester

21st February, 2018
 
Glasgow to Lake District sum-up: 
  • Weather and road conditions: Both wet and dry road, direct low sun, very good road conditions with well visible lines and a consistent surface. Good sampling of curvature, camber and profile
  • Testing:
    • Impact of direct low sunlight on the camera brought new insights on future camera and sensor selection to improve line detection performance
    • Some driving on B roads with only the center line available, for which the system is not currently designed
    • Line detection was kept operational for evaluation purposes to assess ability to detect road edges
  • Performance & findings:
    • Split wet and dry road with bright sunlight generated unusual reflection patterns for camera input - preprocessing function must be developed to improve adaptability of filtering functions; current state processed image was dominated by brighter high-intensity regions
    • Perception of center line on B roads was better than expected despite low radius corners and road profile undulations: This opens up opportunities for adding functionality to enable operation on wider variety of roads than highways
 
Lake District to Manchester sum-up: 
  • Weather and road conditions: Favourable weather conditions, bright soft light with minimal shadows
  • Testing: Some lateral system calibration to overcome most obvious shortfalls with limited success without the lead software developer present
  • Performance & findings: Additional data collection on ACC feature to be used during calibration
The route taken today was always expected to challenge the system, going beyond pure highway driving for which the functionality was originally designed. However, we are very pleased with the current capabilities of perception in these challenging conditions – this gives us a very good base for future developments.

Third update: From Manchester to Cardiff

22nd February, 2018 

  • Weather and road conditions: 
    • Bright sunshine early on, with some cloud later on
    • Ideal road conditions: Both M6 and M5 featured good road surface and high-quality lines allowing prolonged dependable operation. 
  • Testing
    • Camera in different light/sunshine conditions (bright to clouded)
    • Line detection
    • Verification of latest calibration efforts and adaptations
    • Driver input data verification to sensor data in urban environments
  • Performance & findings:
    • Best camera performance in cloudy, dry conditions
    • Bright sunshine testing did present some challenges for the line detection but generated some acceptable results with room for improvement
    • M6 and M5 proved to be perfect testing ground due to highly visible linings
    • This part of the drive will be used for the generation of performance metrics for example target trajectory deviation statistics
    • The ideal conditions enabled prolonged calibration efforts in order to compensate for some shortfalls experiences in day 1 and 2
    • State achieved improved target trajectory holding in medium severity curvatures (previously poor, hugging outside of curvature) but compromises straight line stability – further calibration work and potentially functionality development required in order to handle both states satisfactorily

We are now on the way to the M25 to autonomously cruise around greater London - stay tuned!

Fourth and final update: London calling! An automated drive around greater London

23rd February, 2018

  • Weather and road conditions:
    • The day started cloudy with intermittent sunlight – later in the day the clouds cleared for bright sunshine again
    • Ultimately good conditions for line detection
    • Motorway/highway road surface roughness changes were notably more frequent than on previous roads/days
  • Testing:
    • Operation on the M25 provided a condensed summary of most road conditions faced previously and enabled trial of drastic calibration efforts
    • High traffic density provided complex scenarios for ACC evaluation
    • Special focus on impact of rough road conditions
    • Complex road marking layouts for additional sensor data collection
  • Performance & findings:
    • Logging systems and flight recorder operation proved to be challenging
    • Primary canalyzer laptop refused to boot (power system fault suspected); limited testing due to short battery power with the backup laptop
    • Encountered many complex road marking layouts which were detrimental to line detection performance when combined with lighting condition (reflective patches, ‘scars’ from previous line marker positions, small infrequent cat’s eyes) – Sensor data collected in these scenarios will contribute to future system development
