Objective test driving – Why robots can do it better

Your job: determine whether ‘A’ performs better than ‘B’ in a given set of circumstances. ‘A’ and ‘B’ could be:

Complete cars/ tires/brakes/damper settings/ ESC programs/suspension bushings or any of hundreds of other vehicle parameters.

Vehicle test procedures are generally written to ensure constant ambient and vehicle conditions but it is vital not to overlook the central factor - how is the car being driven?

Even the most experienced test driver cannot repeat like a robot!

Driverless Test System (DTS)
Applications:

With seven Driverless Test Systems already supplied (as of 2010), the DTS is already being used in a wide variety of applications by ABD customers around the world:

Vehicle Dynamics - The full range of objective dynamics tests can be run without a human driver; reducing risk, enhancing the accuracy of the manoeuvre and improving data coherence.

Durability - Durability testing is typically arduous, physically demanding and tedious for the drivers. However, these are ideal conditions for robotized testing.

ADAS Testing – ADAS: advanced driver assist systems. Testing these systems requires the precise positioning and timing of multiple vehicles – impossible for human drivers.

Misuse Testing - Includes driving vehicles over ramps and sand-bank impacts to check airbags only deploy when they should. Very unpleasant for human drivers, but no problem for robots.

DTS base-station
  • The base-station is normally located within line-of-sight of the test track (although this may not be possible for durability testing). The base-station can be installed in a building or even in another vehicle. The base-station software displays real-time information about the vehicle’s position, speed and heading. When multiple vehicles are being tested simultaneously, their relative positions and velocities are also available.
  • Tests can be configured and run from the base-station and the data uploaded immediately afterwards for analysis. Video and audio data channels can also be sent from the vehicle in real-time, allowing the users to check for vehicle problems.
  • Remote controls (a steering wheel and pedals, right) may be used to drive the vehicle from the base-station. An E-stop button allows the vehicle(s) to be stopped quickly in an emergency.
  • By taking the human driver out of the vehicle, ABD’s driverless system enables the most dangerous and arduous vehicle tests to be performed accurately, repeatably and without risk of driver injury.

Soft Crash Target Vehicles

Soft Crash Target Vehicles
Soft Crash Target Vehicles
  • The purpose of the “Soft Crash Target” vehicles is to provide a simulated vehicle that can be used in the development of collision warning and collision mitigation systems. The target vehicle can be programmed to follow a commanded trajectory with high accuracy, and this trajectory can be synchronized with that of the test vehicle to create a close-passing or potential crash scenario that can be used to develop the car’s safety systems. The Soft Crash Target vehicle allows these otherwise dangerous tests to be conducted without fear of significant damage to the test vehicle.

Two versions of Soft Crash Target vehicle are available.

1. The first type uses a central drive box (that was designed according to the dimensions specified by the European ASSESS project) which is surrounded by a set of inflatable cushions to provide impact absorption to prevent damage to the vehicles in a collision. The cushions have a greater depth at the front and rear of the soft crash vehicle than at the sides which allows a greater relative speed of impact in these zones. The system is suitable for collisions with moderate to low relative velocity.

2. The alternative design uses a flat, drive-over, chassis that was developed by Dynamic Research Inc. (DRI). This is fitted with ABD’s control system to provide full compatibility with ABD’s robot systems. DRI provide a foam panel body that fits on top of the drive-over chassis that is assembled rather like a jig-saw puzzle. This system enables high speed collisions to be performed safely, provided that the test vehicle has sufficient ground clearance and suspension travel to ride over the low-profile platform.
