An expected locus of the object is computed on the basis of the positions of the object detected at the prescribed time intervals. An expected locus of the vehicle is also computed. It is determined whether or not there is a danger of collision on the basis of both the expected loci of the object and the vehicle. In this configuration, a periphery monitoring apparatus can be proposed which is capable of determining the danger of collision on the basis of the mutual movements of the vehicle and object.Type: GrantFiled: January 9, 2001Date of Patent: March 30, 2004Assignee: Yazaki CorporationInventors: Masaki Saito, Naoto Ishikawa

Patent number: 6662090Abstract: The present invention provides a protective maintenance service system capable of raising an alarm for the replacement of a part when the degradation of an inspection required part reaches the prescribed criteria of replacement. Of the respective inspection required parts stored in the vehicle inspection parts database for the respective vehicles stored in the vehicle database provided by a business unit in advance, the time of part replacement is determined on the basis of the data detected by a part condition sensor for a part having a part condition sensor, and on the basis of the time, which is obtained from the service life compensated with an actual service environment, for a part without a part condition sensor.Type: GrantFiled: March 13, 2002Date of Patent: December 9, 2003Assignee: Hitachi, Ltd.Inventors: Atsuya Toyama, Tatsuo Yoshioka, Akio Ito, Toshio Manaka, Takashi Nakahara

Patent number: 6563431Abstract: An automatic garage door system includes a controller. The controller receives information on the vehicle's position from a vehicle parking unit. When the automatic system is on, the system determines if the garage door is open via a garage door position sensor. When the garage door is open, the controller signals a remote interface unit located inside the house to indicate that the garage door is open. The vehicle parking unit determines if a car is entering or leaving the garage. When no vehicle is entering or leaving the garage, the garage door is automatically closed after a predetermined time interval. When a vehicle is entering the garage, the vehicle's position is monitored by the vehicle parking unit, which displays the vehicle position information to the vehicle driver with a visual parking indicator.Type: GrantFiled: October 19, 2000Date of Patent: May 13, 2003Inventor: Jay W. Miller, Jr.

Patent number: 6373402Abstract: An apparatus of the invention includes a device for triggering a camera to photograph a vehicle within a traffic intersection, where the triggering of the camera is dependent on the speed of the vehicle before entering the intersection and may also be dependent on presence information. The device includes a sensor system (or “sensor array”) to transmit signals corresponding to a moving vehicle and a control system for processing the signals and triggering the camera. The signals preferably include “position signals” from which a transit time can be calculated, and “presence signals,” from which presence information can be obtained, particularly the location of the rear of the vehicle or the location of the rear wheels of the vehicle. A trigger time for taking a picture of the vehicle may be calculated from the transit time.Type: GrantFiled: June 20, 2000Date of Patent: April 16, 2002Assignee: American Traffic Systems, Inc.Inventor: Gary L. Mee

Patent number: 6100820Abstract: A vehicle detectors with at least one inductive loop is used as a sensor. An oscillator circuit comprises a fixed-frequency oscillator, which is directly connected to one of the inductive loops' two terminals, for purposes of exciting said loop. In addition, a phase/amplitude controller is arranged between the fixed-frequency oscillator and the other terminal, which forms a summation point of the inductive loop to deliver a compensation signal that is derived from the transmit signal in an amplitude-controlled and phase-controlled manner. The inductive loop, the fixed-frequency oscillator and the phase/amplitude controller form a bridge circuit in which (with reference to the resulting voltage at the summation point) the transmit signal and the compensation signal add up to zero in the resting state of the inductive loop. A detection signal for the presence of a vehicle in the detection range of the induction loop is derived from a voltage at this summation point which deviates therefrom.Type: GrantFiled: September 15, 1999Date of Patent: August 8, 2000Assignee: Siemens AktiengesellschaftInventor: Klaus V.
