Complementary Chassis Systems for Ground Vehicles Safety

Redundancy of integrated systems has always been used in order to increase vehicle's safety. Some new technologies are however too expensive to be redundant. This paper proposes a new way to preserve the safety by enabling a kind of complementarity between different chassis systems. Optimization-based control allocation redistribution algorithms are used in order to find the best way to combine conflicting systems. Results have shown that one system can take over another one when a failure occurs making the control logic fault-tolerant and reconfigurable. This better suits future cars as additional chassis systems are intended to be more integrated.
