Test methology, active support systems
At VTI we work to evaluate active safety systems. For example, we investigated whether vehicle manufacturers meet therequirements for ESC systems. VTI works with test methodologyboth on a test track and in our driving simulator.
VTI has a broad expertise in many areas. This allows us to examine the systems capabilities, and how they can be approached from a behavioural science aspect.
Technology for repetable track tests - ALVTI
VTI and Autoliv has through collaboration (ALVTI) developed a suit of technology for evaluation of vehicles on a test track. It can be e.g be used for active and passive safety systems. Productivity, flexibility, reliability and accuracy were all key factors during the development process. Currently, the jointly developed system includes driving robots, autonomous balloon vehicles and autonomous pedestrians.
Active safety systems
More and more vehicles is to be fitted with active safety systems today. These have a functionality that will help driversin critical driving situations. Thus, the system helps reduce the risk of traffic accidents. Anti-skid systems, self-adjusting cruise control and support systems in order to stay in the right laneare some examples of active safety systems.
Within the European research program eVALUE (testing and evaluationmethods for ICT-based safety systems) VTI worked to develop test methods for evaluation of active safety systems. eVALUE focused on the security systems available in today's vehicles, but also examined the future systems.
The project was based not by how "good" specific systems were. Instead, the researchers looked at how the car reacted in specific traffic situations. Each situation represented a common accident situation in traffic. Among other things could be a security system to keep the correct file examined by creating a scenario where the vehicle inadvertently changed file or left the road. This makes it easier for car buyers and other users to understand the evaluation criteria.
Development of test method for snow classification
When the tire must be selected, there is a need for both car owners and tiredealers to have clearer descriptions of tire use. VTI therefore works in a project whose aim is to build a foundation for being able to classify tires into various categories.
This project will investigate and identify VTI what criteria should be included in the winter ratings process. This is carried out primarily with the various tests,both in the laboratory at VTI's "long path", and in test vehicles at Luleå University of Technology on some basis in real environments, mounted oncommon vehicles. Based on these tire tests are criteria that reflect the customer benefits of tire safety on different surfaces. A possible future use of the criteria would, in addition to the purely consumer enlightening, also be a steering tireclassification.
