INTELLIGENT VEHICLE SAFETY DRIVING ENVELOPE RECONSTRUCTION METHOD BASED ON INTEGRATED SPATIAL AND DYNAMIC CHARACTERISTICS

Provided is an intelligent vehicle safety driving envelope reconstruction method on the basis of integrated spatial and dynamic characteristics. Starting from simulating an actual driver's estimation of potential collision risks in the forward driving area, a prediction result of a front vehicle driving behavior is introduced to an environment perception link of the intelligent vehicle; on the basis of the prediction result of the front vehicle driving behavior, a safety driving envelope of the intelligent vehicle is reconstructed by integrating spatial and dynamic characteristics (a safety environment envelope reconstruction and a stable control envelope reconstruction), so as to improve the safety and stability of intelligent vehicle.

20180148069 · 2018-05-31 ·

Systems and methods for implementing and/or validating a model reference adaptive control (MRAC) for human-in-the-loop control of a vehicle system. A first operator model is applied to a first feedback-loop-based MRAC scheme, wherein the first operator model is configured to adjust a control command provided as an input to the MRAC scheme based at least in part on an actual action of the vehicle system and a reference action for the vehicle system with a time-delay. A stability limit of a first operating parameter is determined for the MRAC scheme based on the application of the first operator model to the first feedback-loop-based MRAC scheme. The MRAC scheme is validated in response to determining that expected operating conditions of the first operating parameter are within the determined stability limit of the first operating parameter.
