Post-Impact Vehicle Path Control by Optimization of Individual Wheel Braking Sequences
Other conference contribution, 2010

In this paper the effectiveness of brake-based path control under typical post-impact conditions is investigated. Accident analysis shows that the secondary collision in multiple-events accidents can be mitigated or avoided by reducing the lateral path deviation. In this study a numerical optimization scheme is formulated to minimize the maximum deviation from the original intended lane using individual wheel braking. The optimal braking sequences are analyzed and dynamic switching between several strategies is found to be necessary. In particular, two distinguished strategies are qualified at the vehicle body level. The results can be used to develop a robust closed-loop control strategy.
