Abstract:
A potential collision is predicted by comparing estimates of the time-to-brake (TTB) and the time-to-turn (TTT) of a host vehicle (10) with a computed time-to-collision (TTC) (24; 64, 66, 76). The collision is deemed to be unavoidable when the smaller of TTB and TTT is greater than TTC. The TTT estimate is based in part on the lateral acceleration capability of the vehicle (10), and the lateral acceleration is initialized to a low value corresponding to its instantaneous capability (52), and is set incrementally higher than the actual lateral acceleration when the driver initiates evasive turning (54). The TTT and TTB estimates are increased by the time required to pre-charge the vehicle brakes (70, 80) so that brake pre-charging can be automatically initiated (74, 84) when required to optimize collision mitigation due to braking.

Abstract:
An object awareness determination system and method of determining awareness of a driver (34) of a vehicle (10) to an object (16) is provided. The system includes an object monitor (18) including an object detection sensor (12A) for sensing an object (16) in a field of view and determining a position of the object (16). The system also includes an eye gaze monitor (38) including an imaging camera (30) oriented to capture images of the vehicle driver (34) including an eye (36) of the driver (34). The gaze monitor (38) determines an eye gaze vector (g). The system further has a controller (60) for determining driver awareness of the object (16) based on the detected object position and the eye gaze vector (g).
Abstract:
A turning maneuver assist system (20) and method (100) are provided for assisting the driver of a vehicle (10) with a visual image while turning the vehicle (10). The system (20) includes first and second cameras (22A and 22B) positioned to generate video images on respective first and second sides of the vehicle (10). The system (20) also includes a drop-down display (50) located onboard the vehicle (10) for displaying images generated by the first and second video cameras (22A and 22B). The system (20) further includes a controller (30) for controlling activation of the first and second cameras (22A and 22B) and the presentation of images on the display (50). The controller (30) activates one of the first and second cameras (22A and 22B) and controls the display (50) to output images captured by the activated camera (22A) when the vehicle (10) is determined to be turning. The display (50) is mounted forward and above the driver and moves between a stowed position and a viewable position.
Abstract:
A collision avoidance and warning system (10) and method (50) are provided. The system (10) includes a sensor (12) and a controller (24). The sensor (12) senses an object (18) in a field of view (14), wherein the sensor (12) determines a direct range measurement (D) between the sensor (12) and the object (18) and an angle measurement (A) of the object (18) with respect to the sensor (12). The controller (24) receives the direct range measurement (D) and angle measurement (A) from the sensor (12), and determines if the object (18) is in an in-path area based upon the direct range measurement (D) and angle measurement (A), as a function in a pseudo polar coordinate frame.
Abstract:
A vehicle security monitoring system (20) and method (100) is provided for monitoring the security in detection zones (24A-24D) near a vehicle (10). The system (20) includes motion detectors (26A-26D) positioned to detect motion of an object within security zones (24A-24D) of a vehicle and cameras (28A-28D) positioned to generate video images of the security zones (24A-24D). A display (50) located onboard the vehicle (10) displays images generated by a camera (24A) when the camera (24A) is activated. A controller (34) controls activation of the camera (24A) and presentation of images on the display (50). The controller (34) activates the camera (34A) and controls the display (50) to output images captured by the camera (34A) when a moving object is detected in the security zone (24A).
Abstract:
A parallel parking assistant system (100) integrated with a vehicle (102, V H ) and method (200) thereof are provided, the parking assistant system (100) including a first sensor (106) configured to determine a first distance, a second sensor (109) configured to determine a second distance, and a controller (108) configured to provide commands as a function of the first and second determined distances. The commands include a first command configured to command a steering system (104) to be in a clockwise position while the vehicle (102, V H )is moving in a reverse direction for a first reversing distance, a second command configured to command the steering system (104) to be in a substantially straight position while the vehicle (102, V H ) is moving in a reverse direction for a second reversing distance, and a third command configured to command the steering system (104) to be in a counter-clockwise position while the vehicle (102, V H ) is a moving in a reverse direction for a third reversing distance.
Abstract:
A lane change assist system (20) and method (80) are provided for assisting the driver of the vehicle in maneuvering a lane change. The system (20) includes a range sensor (24) mounted on a vehicle (10) for sensing range to an object (42) in a side detection zone (34) adjacent to one side of the vehicle (10). The system (20) also includes a controller (40) for determining when the side detection zone (34) is clear for the vehicle (10) to change lanes based on the sensed range signal. The controller (40) determines whether there is sufficient space to initial a lane change maneuver based on the sensed range signal and generates an output signal indicative thereof. An output is provided to warning lights (26, 28) indicative of the determined state for initiating the lane change maneuver.
