CESVIMAP researches into vehicles carrying ADAS as standard –Autonomous Emergency Braking (AEB), Lane Departure Warning (LDW) or Lane Keeping System (LKS)… –, to find out how these systems work and what there are limits are.
The main objective is to evaluate the vehicle’s capacity to avoid accidents and, therefore, personal and material damage with direct influence on road safety. Likewise, the incorporation of ADAS sensors can have influence on the cost of repairing the vehicle, since they are located in zones which aree relatively highly exposed to accidents. Thus, in the event of an accident occurring (for instance, parking against a tow ball) this would have major repercussions on the cost of the repair and, therefore, for the profits and losses for insurance companies or the policy holder’s pocket.
It is a question of weighing up the cost and the benefit of these systems, with the starting point being that if an ADAS works properly, the cost of the repair becomes a secondary consideration. However, if the system works badly or even does not work – there have been cases – there is no justification for the increase in the cost of repair and, therefore, the system is hardly worthwhile from the point of view of cost or benefit.
At CESVIMAP, we have designed a characteristic typically urban scenario in which various vehicles, simulated by ABT blocks (AEB Block Tester®) are at a halt; the objective of the blocks is to reproduce the rear end of a standard vehicle, for the purpose of the perception of the vehicle’s sensors. These blocks are manufactured from a foam containing additive with particles of a material which simulates the echo that a radar produces on it, like the one which a real vehicle would produce. The external material is foam, in order not to cause damage to the vehicle, in the event th AEB system does not work properly. The test for motorbike and vehicle detection with overlap is where the vehicles of various manufacturers are most likely to fail, since they are not considered by any test system from other laboratories.
Since 2016, CESVIMAP holds the international registered patent, corresponding to ABT systems ABT (AEB Block Tester®), capable of simulating vehicles without the test vehicle sustaining damage.
Currently, CESVIMAP is conducting research to perform the tests in various scenarios which reproduce the types of frequent accidents.
The analysis finishes with tests on other systems of lower impact on accident rates: Assisted Parking, Blind Spot Warning or Cross Traffic Alert for leaving perpendicular parking spaces.
To do this, we use a qualitative method of technical perception of the tests, putting a value on how they work with three categories: good, average and bad. All the information analysed is compiled into a database, together with the cost of the sensors and the operations to be performed, in the event of their replacement or calibration. As of now, we have fifty or so vehicles of different makes completely analysed; our objective is to increase the number of tests and to carry on participating in the improvement of road safety, one of CESVIMAP’s basic principles.
