A braking system controller receives the cruise controller message and transmits an engine control message based on the cruise controller message. An engine controller receives the engine control message and controls a torque and/or speed of an engine as a function of the engine control message.Type: GrantFiled: February 1, 2010Date of Patent: November 5, 2013Assignee: Bendix Commercial Vehicle Systems LLCInventor: Kenneth A.

Patent number: 8571748Abstract: A method is provided for estimating a propulsion-related operating parameter of a vehicle for a road segment, and for determining routes based on the estimate. The method may be employed, for example, in a vehicle navigation system. In one example method, at least one operating parameter of the vehicle is estimated for the road segment based on information corresponding to the road segment. The propulsion-related operating parameter is estimated for the road segment using the at least one estimated operating parameter and at least one vehicle specific parameter. The at least one vehicle specific parameter is determined by acquiring driving data to determine a plurality of vehicle operating parameters while the vehicle is in operation. At least two of the determined vehicle operating parameters are used in a predetermined relationship that includes the at least one vehicle specific parameter.Type: GrantFiled: February 18, 2010Date of Patent: October 29, 2013Assignee: Harman Becker Automotive Systems GmbHInventors: Sebastian Kluge, Alexey Pryakhin, Peter Kunath

Patent number: 8560200Abstract: Provided is a driving support apparatus for a vehicle. When a stop signal is recognized by a stereo image recognition device, a cruise control unit calculates a traffic signal target acceleration for making a subject vehicle stop at a stop position of the stop signal. When a follow-up cruise target acceleration is not calculated and the traffic signal target acceleration is calculated, the cruise control unit substitutes the traffic signal target acceleration for the follow-up cruise target acceleration. When the follow-up cruise target acceleration and the traffic signal target acceleration are calculated and the traffic signal target acceleration is smaller than the follow-up cruise target acceleration, the cruise control unit substitutes the value of the traffic signal target acceleration for the follow-up cruise target acceleration.Type: GrantFiled: March 28, 2012Date of Patent: October 15, 2013Assignee: Fuji Jukogyo Kabushiki KaishaInventor: Tasuku Maruyama

Publication number: 20130268174Abstract: A driving assist apparatus for a vehicle is provided. The apparatus includes a determination unit that determines a state of a traffic flow in a lane in which a ego-vehicle is driving, on the basis of acceleration of the ego-vehicle and inter-vehicle distances to other vehicles around the ego-vehicle. The apparatus also includes a drive control unit that controls a motion of the ego-vehicle and is capable of switching drive control according to a determination result by the determination unit. The drive control unit switches the drive control when the determination result indicates that the state of the traffic flow is a state of a critical region which is present in a transition period from a free-flow state to a mixed-flow state. Here, the free-flow state is a state in which the probability of occurrence of traffic congestion is low, and the mixed-flow state is a state in which a braking state and an acceleration state of a vehicle are mixed.Type: ApplicationFiled: December 9, 2011Publication date: October 10, 2013Applicant: HONDA MOTOR CO., LTD.Inventor: Takamasa Koshizen

Patent number: 8554397Abstract: The present invention relates generally to ground transportation systems, and more particularly to a fixed guideway transportation system that achieves a superior ratio of benefits per cost, is lower in net present cost and thus more easily justified for lower density corridors, and can provide passenger carrying capacities appropriate for higher density corridors serviced by mass rapid transit systems today. According to certain aspects, the present invention provides a methodology for limiting the rise in headway as the vehicle speed increases. This innovation further allows systems to achieve shorter time separations between vehicles traveling at high speeds, thus significantly improving the utility of fixed guideway infrastructure.Type: GrantFiled: August 25, 2011Date of Patent: October 8, 2013Assignee: Cybertran International Inc.Inventors: Eugene Iwao Nishinaga, Kevin Kohei Nishinaga

Patent number: 8554443Abstract: An ECU designates a value of a variation “Vunder” based on at least one of information about driver's operation, a velocity, and a road surface gradient when an actual velocity “V” is higher than a target velocity, sets a value of a variation “Vtarget” based on the designated value of the variation “Vunder” and the target velocity, adjusts the velocity of the vehicle to the velocity of the set value of the variation “Vtarget”, and determines whether the actual velocity “V” after the adjustment is a value not greater than the value of the variation “Vtarget”. Then, the ECU converges the velocity of the vehicle to the target velocity after it has been determined that the actual velocity “V” after the adjustment is a value not greater than the value of the variation “Vtarget”.Type: GrantFiled: March 6, 2009Date of Patent: October 8, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Motonari Ohbayashi, Ayako Nishimura, Masayuki Naito
