SYSTEM AND METHOD FOR LANE DEPARTURE WARNING
First Claim
Patent Images
1. An integrated detection and warning system for a host vehicle, said warning system comprising:
- a sensor system adapted for sensing and providing sensor data indicative of driver status and vehicular environmental conditions;
a first control system operatively connected the sensor system to receive sensor data therefrom, the first control system being adapted to evaluate the sensor data from and to selectively provide driver assessment data;
a second control system operatively connected to both the sensor system and to the first control system to receive data therefrom, the second control system being adapted to evaluate the sensor data to selectively determine that an adverse condition warning is required and to evaluate the driver assessment data to selectively alternatively provide a low intensity warning control output and a high intensity warning control output; and
a driver warning system operatively connected to the second control system to receive the adverse condition warning control output therefrom, the driver warning system being adapted to selectively alternatively provide a low intensity warning in response to a low intensity warning control output and a high intensity warning in response to a high intensity warning control output.

11. An integrated lane departure detection and warning system for warning a driver of a host vehicle of an adverse lane departure event, said warning system comprising:
-
a driver impairment monitoring system comprising; a first sensor adapted for sensing and providing data indicative of the impairment level of a driver; a first control system operatively connected to the first sensor for receiving data therefrom, the first control system being adapted to evaluate data from the first sensor and to selectively provide a driver impairment output; and a first driver warning system operatively connected to the first control system for receiving driver impairment output therefrom, the first driver warning system comprising at least a first user interface component adapted to selectively provide a driver impairment warning in response to the driver impairment output; and a lane departure monitoring system comprising; a second sensor adapted for sensing and providing data indicative of lane departure; a second control system operatively connected to both the second sensor and to the first control system for receiving data therefrom, the controller being adapted to evaluate data from the second sensor to selectively determine that a lane departure warning is required, to evaluate the driver impairment output to determine a selected level of intensity, and to provide a lane departure warning control output indicating the selected level of intensity; and a second driver warning system operatively connected to the second control system for receiving the lane departure warning control output therefrom, the second driver warning system being adapted to selectively implement a lane departure warning at the selected level of intensity in response to the lane departure warning control output. - View Dependent Claims (12, 18, 19, 20)

13. A method for warning a driver of a vehicle of an adverse condition, the method comprising:
-
determining whether an adverse condition exists; determining the condition of the driver; selecting a warning intensity based on the condition of the driver; and delivering to the driver an adverse condition warning of the selected intensity. - View Dependent Claims (14, 15, 16, 17)
