Method for controlling a motor vehicle to avoid obstacles
A patent application (Publication Number: US20240034311A1) describes a method for controlling a motor vehicle to avoid a target using perception sensors. The method involves merging data from multiple sensors to determine steering wheel angle, vehicle speed, and heading. A target avoidance path is planned as a clothoid and refined based on an optimization problem, steering wheel angle, vehicle speed, and heading. The refinement process includes substeps to improve the path based on various factors. The optimization problem considers reference displacements, vehicle heading, path curvature, and other parameters, with constraints on steering wheel angle and final heading value.
Furthermore, the method includes substeps to determine optimal solutions and refine the path accordingly. If an optimal solution does not exist, the path is extended, and the process is resumed. Constraints on longitudinal and lateral displacements, steering wheel angle, and final heading value are enforced. The system also includes a computation means to implement the control method. Overall, the method aims to efficiently control a vehicle to avoid obstacles by continuously refining the avoidance path based on sensor data and optimization algorithms, ensuring safe and effective navigation.
