20090212993 | COLLISION DETECTION APPARATUS, VEHICLE HAVING SAME APPARATUS, AND COLLISION DETECTION METHOD - A collision detection apparatus incorporated in a vehicle has: a radar that detects an object; and a controller that determines whether there is a possibility of collision between the vehicle and the object based on a result of detection by the radar. A detection-direction center axis of the radar is tilted to right or left by 20° to 60° with respect to a straightforward running direction of the vehicle. | 08-27-2009 |
20090219190 | Method and Device for Measuring the Distance and Relative Speed of Multiple Objects - A method and device are provided for measuring distance and relative speed of a plurality of objects with the aid of an FMCW radar, transmitted signals being reflected by objects, and the reflected signals being received and mixed with the transmitted signals. A combination of distance and relative speed values is assigned to the mixer output frequencies of each frequency ramp for each object, and the distance and relative speed of a possible object are determined from points of intersection of a plurality of distance and relative speed combinations. The apparent (unreal) objects are eliminated by modifying the frequency slope of at least one frequency ramp according to the random principle in a subsequent measurement cycle. | 09-03-2009 |
20090295622 | Ground Vehicle Collision Prevention Systems and Methods - The present invention comprises systems and methods for preventing collisions between aircraft and ground vehicles. In one embodiment, a system includes a proximity detection unit and a transducer proximate to a selected structural portion of an aircraft, the proximity detection unit being operable to emit ranging signals through the transducer and to receive reflected signals through the transducer to determine the position of an object within a ranging area adjacent to the structural portion. The system further includes an alarm device coupled to the proximity detection unit that is responsive to a signal generated by the proximity detection unit. In another embodiment, a method includes determining a distance between the ground service vehicle and a selected structural portion of the aircraft when the vehicle is positioned in a ranging area about the aircraft. The method further includes generating a proximity alarm based upon the distance. | 12-03-2009 |
20120235853 | COLLISION AVOIDANCE APPARATUS - A collision avoidance apparatus capable of executing an appropriate vehicle control in order to avoid a collision between an own vehicle and a movable object is provided. A collision avoidance apparatus for avoiding a collision between an own vehicle and a movable object includes: a laterally-existing movable object detector for detecting for a movable object that approaches from a direction lateral to the own vehicle; a side collision determination section for determining whether or not a risk that the own vehicle and the movable object collide with each other is high, when the laterally-existing movable object detector has detected the movable object that approaches from the direction lateral to the own vehicle; a passage and avoidance determination section for determining, when the risk that the own vehicle and the movable object collide with each other is determined to be high, whether or not a possibility that a collision between the own vehicle and the movable object can be avoided by the own vehicle passing in front of the movable object, is high; and an accelerated state/decelerated state controller for controlling the own vehicle to be in one of an accelerated state and a decelerated state, according to a determination result of the passage and avoidance determination section. | 09-20-2012 |
20120326917 | ACCIDENT PREVENTION SYSTEM AND A VEHICLE INCLUDING THE ACCIDENT PREVENTION SYSTEM - A vehicle with an accident prevention system is disclosed. The vehicle also has a foot brake for stopping the vehicle. The system includes a sensor arrangement for sensing an object behind a rear end of the vehicle that generates an object recognition signal when it senses an object within range behind the vehicle. The sensor arrangement includes passive IR sensors or reflected pulse sensors such as sonar or radar sensors on the rear end. A controller generates an accident prevention response signal on receiving an object recognition signal from the sensor arrangement. A brake applicator is operatively coupled to the brake to stop the vehicle when the controller generates a response signal. Conveniently the system includes an alarm for sounding an alarm signal. A method for preventing an accident where a vehicle which is reversing at low speed collides with a person is also disclosed. | 12-27-2012 |
20130201053 | Crash Avoidance System - A crash avoidance system is provided for a vehicle. The system utilizes thrusters to decrease the vehicle's velocity and brake time. The thrusters can also maneuver the vehicle from a possible crash. The system consists of a controller system which communicates with the thrusters that are strategically placed on the vehicle and at least one camera and radar sensors. The system also consists of an on-board pressurized gas source for the thrusters to produce a force to great and quick enough to avoid crashes. In case the driver loses traction and control for any reason, the system also communicates with the vehicle's traction control system. | 08-08-2013 |
20140300505 | Vehicle collision shield - A method for avoiding collisions with an aircraft ground-services vehicle includes using a proximity sensor attached to the ground-services vehicle to generate a proximity signal, and using a processor that stores a three-dimensional map of the ground-services vehicle's outer geometry. The three-dimensional map is modifiable upon in-use changes to the 3-D geometry of the ground-services vehicle. The processor uses the three-dimensional map and the proximity signal to determine whether a predetermined 3-D envelope around the vehicle has been breached, and notifies the vehicle of a breach. | 10-09-2014 |
20140347207 | PROBABILISTIC TARGET SELECTION AND THREAT ASSESSMENT METHOD AND APPLICATION TO INTERSECTION COLLISION ALERT SYSTEM - A system and method for providing target selection and threat assessment for vehicle collision avoidance purposes that employ probability analysis of radar scan returns. The system determines a travel path of a host vehicle and provides a radar signal transmitted from a sensor on the host vehicle. The system receives multiple scan return points from detected objects, processes the scan return points to generate a distribution signal defining a contour of each detected object, and processes the scan return points to provide a position, a translation velocity and an angular velocity of each detected object. The system selects the objects that may enter the travel path of the host vehicle, and makes a threat assessment of those objects by comparing a number of scan return points that indicate that the object may enter the travel path to the number of the scan points that are received for that object. | 11-27-2014 |
