Publication number: 20040060757Abstract: Automotive collision avoidance systems operable in inclement weather and harsh environments such as motorways are presented. Anticollision systems of these inventions are configured with specialized source and detection subsystems to provide operation with energy beams having relatively long wavelengths. Optical beams characterized as middle infrared or ‘mid-IR’ are used for their ability to stand up against factors which tend to strongly attenuate optical beams of more common spectra such as near IR. In some versions, specialized quantum cascade lasers are arranged as optical beam sources. Quantum cascade lasers efficiently generate high energy beams of long wavelength; for example between 3 and 30 micrometers. These beams of long wavelength tend to better penetrate free-space contaminated with small particulate matter. In addition, these systems include specialized detection subsystems which operate with high detectivity in the mid-IR spectral region.Type: ApplicationFiled: September 26, 2002Publication date: April 1, 2004Inventor: James Plante

Patent number: 6604592Abstract: A method and device prevents damage to a vehicle approaching an obstacle, such as, for example, a loading ramp, while traveling in reverse. When a vehicle, particularly a vehicle train consisting of a towing vehicle and a trailer or semi-trailer, approaches an obstacle in reverse travel, there exists the possibility that the vehicle may impact the obstacle as a result of an erroneous estimation or inappropriate driving maneuver, potentially resulting in damage to the vehicle and/or to the obstacle.

In accordance with the invention, the driver of the vehicle is assisted during reverse travel such that damage due to excessive impact is automatically avoided, independently of the driver's actions. A distance sensor is installed on the vehicle, near the tail, which transmits a signal representative of the distance from an obstacle to an electronic control device.Type: GrantFiled: July 2, 1999Date of Patent: August 12, 2003Assignee: Wabco GmbHInventors: Frank Pietsch, Detlev Neuhaus

Patent number: 6554089Abstract: The vehicle deceleration control apparatus controls deceleration given to a vehicle according to a distance from a vehicle ahead, which is directly measured or estimated based on an accelerator operating condition, so that the smaller the distance from a vehicle ahead, the greater is an assist deceleration. The vehicle deceleration control apparatus is capable of giving an appropriate deceleration according to traffic conditions.Type: GrantFiled: December 8, 2000Date of Patent: April 29, 2003Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kunihito Sato, Nishiyama Keiichi

Patent number: 6553283Abstract: A transmission wave is applied to a predetermined angular range in a width-wise direction of a vehicle. Object-unit data pieces containing at least data pieces representing distances to objects in correspondence with vehicle-width-wise direction angles are generated on the basis of a reflected wave. A determination is made as to whether each object is moving or stationary on the basis of a speed of the vehicle and a relative speed of the object. From the object-unit data pieces, ones are extracted which are effective for road shape recognition on the basis of a result of determining whether each object is moving or stationary. Ones of the extracted object-unit data pieces which represent monotonically increasing distances as viewed along one of clockwise and counterclockwise angle directions are grouped to generate data representing a road-side-object group. A road edge is recognized on the basis of the data representing the road-side-object group.Type: GrantFiled: February 27, 2001Date of Patent: April 22, 2003Assignee: Denso CorporationInventors: Noriaki Shirai, Katsuhiro Morikawa

Publication number: 20030070852Abstract: The guidance assembly includes a diode device (30, 130, 230) for emitting a vertical line of laser light (32). The assembly is characterized by an alignment mechanism for maintaining the vertical line of laser light (32) in parallel alignment with gravity to compensate for misalignment of the upright axis of the carriage (12) from vertical to maintain the vertical line of laser light (32) aligned with gravity as the carriage (12) moves over an uneven plot. In the first and second embodiments of FIGS. 2 through 5, the alignment mechanism includes a rotary motor (38 and 138), for rotating the diode device (30, 130) for rotating the vertical line (32) relative to the upright axis of the carriage (12). The third embodiment of FIGS.Type: ApplicationFiled: October 16, 2001Publication date: April 17, 2003Inventor: Paul G. Angott

Patent number: 6546327Abstract: A running control apparatus and method control the state of running of a vehicle based on a relative positional relationship between the vehicle and a preceeding vehicle. In a case where a brake is actuated if the deceleration deviation obtained by subtracting an actual deceleration from a target deceleration is at least a third threshold &Dgr;&agr;s3, the brake is actuated provided that an object body detected by a laser radar device is a preceeding vehicle and that the same-lane probability that the preceeding vehicle is running in the same lane as the vehicle is at least a set probability. Thus, the brake is actuated when there is a high probability that braking is needed. Therefore, erroneous operation of the brake can be reduced.Type: GrantFiled: August 6, 2001Date of Patent: April 8, 2003Assignee: Toyota Jidosha Kabushiki KaishaInventors: Akira Hattori, Nobuyuki Furui, Hironori Miyakoshi

Patent number: 6542807Abstract: A device for representing on a display device a control situation determined by a motor vehicle distance control device, the distance control device being connected to a sensor which detects the coordinates and the relative speed of the obstacles located ahead of the motor vehicle and relays them to the distance control device, which determines the expected lane of the motor vehicle, the distance control device determining from these data a control object with reference to which the distance of the motor vehicle is controlled. Referring lso a device referring the multiplicity of the data required for distance control in a motor vehicle can be checked in a simple way for their correctness, the distance control device (3) is connected to a display control device (14) which converts the data detected by the sensor (9) and calculated by the distance control device (10) into an approximately true-to-scale plan view of the control situation ahead of the vehicle (1), which is displayed on the display device (15).Type: GrantFiled: December 21, 1999Date of Patent: April 1, 2003Assignee: Mannesmann VDO AGInventors: Robert Bienias, Sascha Heinrichs-Bartscher

Patent number: 6542111Abstract: A motor vehicular collision warning system including a scanned beam sensor, a signal processor, and a vehicle interface system that initiates warnings to the driver or adaptively controls the vehicle. Scene data is used to predict the path of the roadway in front of a subject vehicle. Reflections from manmade and natural scene objects are extracted from the scene data to define a linear feature edge. Once the feature edge is determined, the predicted path of the subject vehicle can be determined using information regarding the vehicle trajectory and the feature edge.Type: GrantFiled: August 13, 2001Date of Patent: April 1, 2003Assignee: Yazaki North America, Inc.Inventor: Terry B.

Patent number: 6536549Abstract: The invention relates to a method for controlling the steering angle of a steered wheel of a vehicle and a system to carry out this method. A control unit (9) controls an adjustment drive (5, 7) to alter the steering angle of the steered wheel, upon an alteration to a position of a steering member (13). The extent of the alteration to the steering angle is dependent on whether an obstacle for the vehicle is detected or not by means of a distance meter (17) coupled with the control unit (9). If an obstacle is detected at high speeds, then steering angle alterations are possible which would not be permitted by the control unit at normal driving operation. Thereby, in emergency situations the driver is to be given the possibility of being able to drive past the obstacle by a steering response characteristic which is more intense.Type: GrantFiled: May 25, 2001Date of Patent: March 25, 2003Assignee: TRW Automotive Safety Systems GmbH & Co.
