D20.54 HMI Tests in Simulator
SASPENCE
Confidential document
Executive Summary
The main goal of SASPENCE is to develop and evaluate an innovative system able to perform the Safe Speed and Safe Distance concept, that means to help the driver in avoiding accident situations related to excessive speed or too small headway. So, the system should co-operate seamlessly with the driver, suggesting the proper velocity for the given condition (road structure, traffic situation, etc.) preventing risky and dangerous situations and thus avoiding collision. This support is done through a Human Machine Interface (HMI). It is essential that the HMIs are easily understandable by the driver and that they induce a suitable reaction to the danger, otherwise the system is worthless.
The simulator tests are the second step of the HMI design process that counts three of them. After the static tests that have enabled to show up the preferred visual, haptic and acoustic HMI, 8 combinations of HMI have been tested in dynamic conditions in the PSA driving simulator while part of the SASPENCE modules were running and tested. These tests should enable us to understand which HMIs are the best for the driver, that is to say, which HMI makes it possible to give the SASPENCE information in the clearest way to the driver. The main aims of these tests were to evaluate the effects of the SASPENCE system on drivers’ behaviour and to give recommendations for the HMI to be installed in the two test-cars, according to drivers’ preference and the efficiency of the HMI.
