Cornering stability improvement by gyro moment for narrow tilting vehicle

The aim of this work is to improve the cornering stability of narrow tilting vehicle by gyro moment. The proposed approach is to counterbalance the instability (wheel lifting) caused by the tilt actuator with gyro moment. A four-wheel narrow tilting vehicle is modeled in a multibody dynamics software to conduct two vehicle motion simulations with hard cornering. The objective of simulation A is to investigate the gyro moment effects on the vehicle inner wheel load (wheel lifting), and the purpose of simulation B is to validate the proposed approach with the improvement of vehicle lateral acceleration (rollover resistance). The simulation results have shown improved stability with no wheel lifting during hard cornering, and higher lateral acceleration. These have proven our proposed approach of applying gyro moment to further improve the cornering stability of narrow tilting vehicles.
