A guide to assessing Active Adaptive Secondary Safety systems. Prepared for the Department for Transport, Vehicles, Standards and Engineering Division.

This Guidance Note is intended to assist in the assessment of advanced systems to protect car occupants in frontal and side impacts and pedestrians in collisions with car fronts. It is based on a programme of research carried out by TRL Limited and considers three types of systems. These are : a system to protect front seat occupants in frontal impacts; a system to protect front seat occupants in side impacts, and a system that could be fitted to the front of a car to protect pedestrians. An implicit part of all of the systems is an electronic control unit and various sensors and a section relates to these components. This Guidance Note is not a legal document and compliance does not guarantee compliance with any regulatory requirement. (Author/Publisher)
