This paper presented a control algorithm to enhance vehicle roll stability during tripped rollover situations. The developed control algorithm of DYC was implemented in commercially available vehicle simulation software to simulate the vehicle behaviour on various road surfaces and due to various inputs. To provide a realistic simulation environment, a tyre model suitable for simulating vehicle behaviour on dirt and gravel roads was also developed. Simulation results show that the proposed control algorithm helps stabilise vehicle roll response and prevent vehicle rollover for the studied manoeuvres. Cornering stiffness estimation was also observed, and it was shown that the DYC is capable of estimating tyre cornering stiffness on various driving surfaces by changing the values in the adaptation gain matrix. It should be noted that the proposed control algorithms do not ensure vehicle roll stability for every possible driving surface and every possible vehicle manoeuvre. Future work in this area of research should include the testing of the proposed control algorithms on a variety of three-dimensional driving surfaces for a variety of potential emergency manoeuvres.
