Lane keeping system for autonomous vehicle in wind conditions
First Claim
1. A lane keeping system for a vehicle comprising:
- a pressure sensor configured to generate a signal indicative of a pressure;
a safety restraint system (SRS) controller in communication with the pressure sensor, the SRS controller configured to determine a collision event in response to the signal and activate a safety restraint component in response to the determined collision event; and
a lane keeping system (LKS) controller in communication with the pressure sensor, the LKS controller configured to determine a lateral wind force on the vehicle in response to the signal, the LKS controller configured to determine a correction in response to the determined lateral wind force to maintain the vehicle along a desired path.

Abstract
A lane keeping system includes an absolute pressure sensor located in a door on each of opposing sides of a vehicle. Each sensor generates a signal indicative of a door cavity pressure on that side of the vehicle. A safety restraint system (SRS) controller is in communication with the pressure sensor. The SRS controller is configured to determine a collision event in response to the signal (e.g., increased pressure in the door as it is crushed) and activate a safety restraint component in response to the determined collision event. A lane keeping system (LKS) controller is in communication with the pressure sensors. The LKS controller determines a lateral wind force on the vehicle in response to the signal from each pressure sensor. The LKS controller determines a correction in response to the determined lateral wind force to maintain the vehicle along a desired path.

18. A method of maintaining a vehicle along a desired path comprising the steps of:
-
determining a differential pressure using first and second absolute pressure sensors, wherein the first and second absolute pressure sensors are respectively arranged within first and second door cavities arranged on opposite lateral sides of the vehicle; determining a correction from the pressure differential; and adding a wind compensation value to at least one of a commanded steering angle and a desired suspension stiffness based upon the correction. - View Dependent Claims (19)
