Adaptive cruise control with stationary object recognition
First Claim
1. A method for controlling a vehicle, the method comprising:
- using a controller topredict the vehicle'"'"'s path;
detect a stationary object within the predicted path based on a signal received from an object detection sensor;
determine an acceleration of the vehicle is greater than a predetermined acceleration threshold; and
,maintain the acceleration;
wherein using a controller to predict the vehicle'"'"'s path includespredicting a vehicle trajectory based on a vehicle yaw rate, andgenerating a path width based on the predicted vehicle trajectory and a width of the vehicle; and
wherein generating a path width includesdetecting a change in direction, andincreasing the path width based on a magnitude of the change in direction.

Abstract
An ACC system and object detection method for a vehicle. The ACC system includes a vehicle parameter sensor, an object detection sensor, and a controller. The controller is configured to calculate the vehicle'"'"'s path based on a signal from the parameter sensor, detect an object based on the vehicle'"'"'s path and a signal from the object detection sensor, determine an acceleration of the vehicle, and prevent the acceleration of the vehicle from increasing while the object is detected and the acceleration of the vehicle is greater than a predetermined acceleration threshold. The object detection method includes identifying stationary objects in a path of a vehicle and limiting an acceleration of the vehicle when the acceleration is above a threshold and a stationary object is identified.
