As these systems continue to develop and become ubiquitous on the roadways, it is more important than ever to have clear expectations for performance and ensuring safety.
This report includes specific design recommendations and details of the performance of these systems in our testing. The following summarizes CR’s recommendations for manufacturers. These high-level recommendations are intended to provide guidance on designing active driver assistance systems that drivers want, will use, and have safeguards in place.
✓ Direct driver monitoring and management is essential. Hands on wheel warnings are not sufficient. Camera-based (vision and/or infrared) systems are more effective.
✓ Systems should not penalize the driver for engagement. The driver should always maintain control of mode selection. There should be no system-initiated standby mode in which the system controls when it does and does not provide steering assistance.
✓ Lane keeping systems should keep the vehicle in the center of the lane. Our experience, and the results from CR member surveys, indicate that drivers expect the systems to hold the vehicle in the center of the lane—and if it doesn’t do so, they will likely simply stop using the system. Multiple LKA systems, regardless of design intent or other rationale, cause confusion.
✓ Systems should know the driver’s state and keep drivers safe when they need it most. The system should stay on and not penalize the driver for not responding. If the
driver does not respond to warnings, the system should try to do everything possible to safely bring the vehicle to a stop then call for help.
