Test and validation of novel Lane-Departure Prevention System
2016
The active safety of road vehicles includes the use of electronic controls for autonomous emergency braking and avoiding unstable yaw motion. This paper focuses on a different critical situation when the vehicle's overspeeds on a curve road. In this paper, a novel approach to road departure prevention is derived from a recently published control method: parabolic path reference (PPR). Previous work has compared the PPR algorithm with a more conventional electronic stability control (ESC) algorithm implemented in the high-fidelity simulation software CarMaker to validate the performance of PPR. Based on the same control theory, in this paper we take consideration of vehicle entry speed into the known curve and then simulate the vehicle performance during the whole control period in different conditions. The experimental results presented demonstrate that the vehicle can achieve improved stability and velocity-keeping performance across a range of different drivers.
