Patent number: 11137493Abstract: A system and method for sensing precipitation conditions near a vehicle. The precipitation radar system is mounted on the vehicle and includes a transmitter, a receiver, and an electronic control unit. The method transmits radar signals from the transmitter; receives reflected radar signals at the receiver; determines response information from the reflected radar signals for a region of interest; and uses the response information to determine precipitation conditions for the region of interest. The region of interest is defined, at least in part, by a range and the response information includes phase data, amplitude data, or both phase and amplitude data based on the reflected radar signals. The method and system may then use the precipitation conditions to control other responsive vehicle actions, such as activating a windshield heater, a windshield defroster, a windshield wiper or a combination thereof.Type: GrantFiled: October 15, 2018Date of Patent: October 5, 2021Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Daniel Flores Tapia, Stephen W. Decker, Stephen W. Erskine

Patent number: 10928507Abstract: The present application generally relates to improve accuracy and sensitivity in a vehicular radar system through improved radar beamforming by initially detection of potential objects using a field of view image and image processing techniques. Specifically, a system and method are taught for performing object segmentation and/or contouring on an image corresponding to a radar field of view. The detected objects from the image are combined with the raw radar data to generate a beamformed radar data.Type: GrantFiled: June 13, 2018Date of Patent: February 23, 2021Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Daniel Flores Tapia, Stephen W.

Patent number: 7084385Abstract: A range discriminating optical sensor for use in a vehicle safety system is provided. The range discriminating sensor is designed to create a small depth of field such that objects at a range outside of the depth of field are eliminated from the image. Generally, the optical sensor uses a large aperture to limit the depth of field. An electronic imaging element is used to detect the image projected by the lens. The electronic imaging element may have a small pixel size which further reduces the depth of field. A signal processor can be used to determine the distance from the image sensor with objects with the selected depth of field appearing in focus and those outside of the depth of field appearing out of focus.Type: GrantFiled: August 19, 2003Date of Patent: August 1, 2006Assignee: Autoliv ASP, Inc.Inventors: Stephen W. Decker, Bernard DeMersseman

Patent number: 6993422Abstract: A system for adjusting a height of a first road vehicle with respect to the ground prior to impacting a second road vehicle is disclosed. The system includes a predictive crash sensor mounted to the first vehicle for sensing the second road vehicle, a control unit, and a height adjustment apparatus. The control unit is in communication with the predicative crash sensor for receiving a predictive crash signal and determining whether the first and the second road vehicles will collide. The height adjustment apparatus is mounted to the first road vehicle and in communication with the control unit. The height adjustment apparatus includes a shock absorber, a bladder, and a first valve. The shock absorber is mounted at a first end to a vehicle body of the first road vehicle and at a second end to a vehicle axle of the first road vehicle. The bladder is fixed at a first end to the first end of the shock absorber and at a second end to the second end of the shock absorber.Type: GrantFiled: September 25, 2003Date of Patent: January 31, 2006Assignee: Autoliv ASP, Inc.Inventors: Bernard De Mersseman, Saeed D.

Patent number: 6272411Abstract: A system for sensing the presence, position and type classification of an occupant in a passenger seat of a vehicle, as well as for sensing the presence of a rear-facing child seat therein, for use in controlling a related air bag activator control system to enable, disable or control inflation rate or amount of inflation of an air bag. The sensor system employs sensor fusion, a process of combining information provided by two or more sensors (24, 26), each of which “sees” the world in a unique sense. In a preferred embodiment, infrared sensor inputs (78) and ultrasonic sensor inputs (79) are combined in a microprocessor by a sensor fusion algorithm (80) to produce an occupancy state output signal (85) to the air bag controller.Type: GrantFiled: September 30, 1998Date of Patent: August 7, 2001Assignee: Robert Bosch CorporationInventors: Anthony P.

Patent number: 6249729Abstract: An automotive occupancy sensing system and method for use in conjunction with airbag deployment systems, by which occupant nature, location and motion parameters within the vehicle interior are determined by ultrasound (US) and/or infared sensors. (IS). Criteria for airbag disablement or airbag modified/partial deployment are used to determine whether appropriate disablement or modified/partial deployment control signals are transmitted to the vehicle airbag deployment system. More particularly the system establishes a Keep Out Zone (KOZ) within the vehicle interior relative to the dashboard or instrument panel and determines actual or imminent incursions by occupants into the KOZ to produce a Keep Out Zone Incursion (KOZI) signal, and determines crash-imminent signal (CIS) criteria derived from one or more sensors within the vehicle. Both the KOZI and the CIS may be used to increase the rate of US pinging as well as to determine airbag disablement/modified deployment criteria.Type: GrantFiled: October 24, 1997Date of Patent: June 19, 2001Assignee: Robert Bosch CorporationInventors: Anthony P. Corrado, Ralf Seip, Stephen W. Decker
