Publication number: 20150221222Abstract: A traffic control system for allowing vehicles to travel unattended while maintaining their inter-vehicular distances without interfering with each other includes an onboard control apparatus mounted on the vehicles; and a traffic control apparatus which divides tracks for multiple vehicles into a plurality of sections and performs a blocking control to assign non-overlapping travelable sections to the multiple vehicles as a permitted travel section. The onboard control apparatus sets a travel permission request starting distance that is longer than a stoppable distance on the basis of the current speed of the vehicle and repeatedly transmits a travel permission request and current position information to the traffic control apparatus until the next travel permission is obtained when the remaining length of the permitted travel section has become shorter than the travel permission request starting distance in the advancing direction of the vehicle.Type: ApplicationFiled: September 11, 2013Publication date: August 6, 2015Inventors: Tomoyuki Hamada, Kazuhiro Sugawara, Katsuaki Tanaka, Masaki Kanai

Publication number: 20150206104Abstract: The maintenance management device 3 includes an error status diagnosis unit 11, a grace period estimation unit 14, a maintenance cost estimation unit 15, and a screen display unit 17. When the error status diagnosis unit 11 has diagnosed the occurrence of an anomaly, the grace period estimation unit 14 estimates a first grace period leading up to the occurrence of a failure. The maintenance cost estimation unit 15 estimates the cost of corrective maintenance incurred when the failure occurs after the elapse of the first grace period. The screen display unit 17 displays a combination of the first grace period and the cost of corrective maintenance. Alternatively, the grace period estimation unit 14 estimates a second grace period over which preventive maintenance may be postponed without a failure.Type: ApplicationFiled: July 10, 2013Publication date: July 23, 2015Inventors: Hideaki Suzuki, Kozo Nakamura, Shinya Yuda, Munetoshi Unuma, Junsuke Fujiwara, Takayuki Uchida, Katsuaki Tanaka, Mitsuo Aihara, Teruo Nakamura, Nobuyoshi Hirowatari, Hiroshi Ogura

Patent number: 8862390Abstract: To advance a dump truck quickly and smoothly to a position where target loading work will be performed relative to an excavating machine, the dump truck is placed in loading target position relative to the excavating machine. Geographic position is detected from GPS satellites of a GPS receiver of the dump truck. The position and direction of the geographic position is transmitted to the excavating machine as a target position image. The target position image and an approach route leading to the position are displayed on a dump truck display when the truck thereafter approaches the position. The dump truck thereafter approaches the position, and the truck is driven so that a current position image advances along the approach route to the target position image, whereby the dump truck is placed in the set loading image target position.Type: GrantFiled: March 27, 2012Date of Patent: October 14, 2014Assignee: Hitachi Construction Machinery Co., Ltd.Inventors: Kazuhiro Sugawara, Hiroshi Ogura, Katsuaki Tanaka, Teruo Nakamura

Patent number: 8548664Abstract: In an autonomic traveling apparatus for a vehicle, vehicles usually travel an independent travel lane and when there are two approaching vehicles on the independent travel lane, they switch to pass-by lanes to pass by each other. To do this switching operation effectively, respective vehicles check and obtain road conditions around them while they are traveling and the obtained road conditions are transmitted to and collected by a travel administration center so that the road conditions at various points along the lanes can be obtained from the travel administration center. Accordingly, when the autonomic traveling trucks approaching each other and supposed to pass by each other, switch to the associated pass-by lanes, they change travel lanes avoiding the point of bad road condition on the basis of the road conditions sent from the travel administration center.Type: GrantFiled: November 9, 2010Date of Patent: October 1, 2013Assignee: Hitachi, Ltd.Inventors: Takayuki Uchida, Yukihiro Kawamata, Katsuaki Tanaka, Mikio Bando
