20100171641 | METHODS AND SYSTEMS FOR MONITORING VEHICLE MOVEMENT - A method for monitoring vehicle movement for use in a first vehicle includes the steps of determining a lane location at a first point in time, determining a position of a second vehicle at a second point in time, the second point in time being subsequent to the first point in time, and determining a path of the second vehicle based at least in part on the position of the second vehicle and the lane location. | 07-08-2010 |
20100179781 | METHODS AND SYSTEMS FOR CALIBRATING VEHICLE VISION SYSTEMS - A method for calibrating a vision system of a vehicle includes the steps of projecting a pattern in proximity to the vehicle and calibrating the vision system using an image of the pattern generated by the vision system. | 07-15-2010 |
20130131905 | SYSTEM AND METHOD FOR CLOSED-LOOP DRIVER ATTENTION MANAGEMENT - A method and system may manage the driver's attention while driving. The driver may be driving using an autonomous driving system or limited-ability autonomous driving system. A method may detect, by a sensor, characteristics of a driver; determine, based on the detected characteristics of the driver, whether the driver exercises sufficient supervisory control of the vehicle; and provide a series of one or more prompts, wherein each prompt's intrusiveness is related to the determination of whether the driver exercises sufficient supervisory control of the vehicle. | 05-23-2013 |
20130131906 | STEERING WHEEL DEVICE FOR INDICATING REQUIRED SUPERVISORY CONTROL OF A VEHICLE AND METHOD FOR USE - A method and system may manage the driver's attention while driving. The driver may be driving using an autonomous driving system or limited-ability autonomous driving system. A steering wheel device may indicate to the driver a level of required supervisory control of a vehicle. The steering wheel device may include indicators to flash lights, vibrate, or provide other indicators. The indicators may have distinct levels of intensity for each level of supervisory control required to safely control a vehicle. | 05-23-2013 |
20130131907 | SYSTEM AND METHOD FOR MANAGING MISUSE OF AUTONOMOUS DRIVING - A method and system may prevent misuse of an autonomous driving system by providing at least one prompt at least one prompt for a driver of a vehicle. A sensor may whether the driver responds to the prompt. A processor may determine whether the driver exercises sufficient supervisory control of the vehicle, based on whether the driver responds to the prompt. The processor may disengage the autonomous driving system if the driver fails to exercise sufficient supervisory control of the vehicle. The processor may further reduce the vehicle's speed if the driver continues to misuse the autonomous driving system. | 05-23-2013 |
20140139341 | SYSTEM AND METHOD FOR AUTO-CORRECTING AN AUTONOMOUS DRIVING SYSTEM - A method and system for driver attention management system may include means for closed-loop diagnostics. A convenience message may alert a driver of an item of interest to the driver. A sensor may detect the driver's response to the convenience message. Based on the response to the convenience message, the characteristics of an attentive response from the driver may be determined. The determined attentive response may be used by a driver attention management system. The driver attention management system may be able to diagnose errors in the sensors that are used in the driver attention management system. The driver attention management system may also be able to determine whether a driver is exercising sufficient supervisory control of a vehicle by determining whether the driver is attentively responding to prompts provided by the driver attention management system. The driver attention management system may be used in an autonomous or semi-autonomous driving system. | 05-22-2014 |
20140214256 | STEERING SYSTEM FOR AN AUTONOMOUSLY DRIVEN VEHICLE AND METHODS OF STEERING THE SAME - A steering system for an autonomously driven vehicle and methods of steering the vehicle are disclosed. A brake device is operable in a first phase to brake the vehicle when a power steering controller is in a first mode and operable in a second phase to steer the vehicle when the power steering controller is in a second mode. A main controller is in communication with a friction device to signal the friction device to actuate to a disengaged position when the power steering controller is in the first mode and the brake device is in the first phase, and signal the friction device to actuate to an engaged position to secure a steering wheel in an initial position when the power steering controller is in the second mode and the brake device is in the second phase to allow the brake device to steer the vehicle. | 07-31-2014 |
20140240478 | DRIVER MONITORING CAMERA SYSTEM - A driver monitoring camera system for a vehicle includes a camera system and an optical beam shaper. The camera system has an exit field of view central axis oriented more vertical than horizontal with respect to a set of orthogonal x, y and z axes, where the z-axis defines a direction line indicative of a vertical direction. The optical beam shaper is disposed in optical communication with the camera system and optically between the camera system and an operator of the vehicle. The optical beam shaper is structurally configured to direct an image of a face of an operator of the vehicle toward the exit field of view of the camera system, and is structurally configured to compress the image in the vertical direction to define a compressed image having a height to width aspect ratio of less an uncompressed height to width aspect ratio of the image. | 08-28-2014 |
20140277893 | STEERING SYSTEM FOR AN AUTONOMOUSLY DRIVEN VEHICLE AND METHODS OF STEERING THE SAME - A steering system for an autonomously driven vehicle and methods of steering the vehicle are disclosed. A main controller signals a secondary steering assembly to operate in a first phase when a power steering controller is in a first mode and a second phase to steer the vehicle when the power steering controller is in a second mode. The main controller signals a friction device to actuate to a disengaged position when the power steering controller is in the first mode and the secondary steering assembly is in the first phase, and to signal the friction device to actuate to an engaged position to secure a steering wheel in an initial position when the power steering controller is in the second mode and the secondary steering assembly is in the second phase to allow the secondary steering assembly to steer the vehicle. | 09-18-2014 |
