Stability Survey Of 4ws Car With Double Lane Change Manoeuvre Test Track

When a vehicle travels along a roadway, its path of motion becomes highly intricate. The presence of lateral forces and tire deformations means the vehicle’s actual trajectory deviates from the intended path, particularly at higher speeds. This discrepancy can compromise vehicle stability, potentially culminating in accidents. To mitigate these issues, the four-wheel steering system (4WS) or all-wheel steering system allows for the manipulation of all wheels, enhancing stability at elevated speeds and diminishing the steering radius at lower velocities. This research examined vehicular turning scenarios using the dual-lane change test as outlined in ISO 3888-2:2011. In scenarios where vehicle control was implemented, cars adhered closer to the ideal trajectory and successfully navigated through the test corridor.
