  • Patent number: 10308248
    Abstract: Disclosed herein is a control apparatus and method for improving fuel efficiency in a CACC system, which can improve fuel efficiency through control of a vehicle speed so that a vehicle travels using an optimized cost in consideration of a target vehicle speed, current vehicle speed, minimum driving speed set in the vehicle, and a deceleration distance if the vehicle that uses the CACC system senses a forward vehicle and enters into a CACC active mode. The control method for improving fuel efficiency in a CACC system includes setting a target speed profile based on a target speed of the subject vehicle and an expected driving path, determining whether a target vehicle to be followed by the subject vehicle exists, and controlling the driving speed of the subject vehicle according to the set target speed profile depending on whether or not the target vehicle exists.

  • Patent number: 10239522
    Abstract: In an inter-vehicle control apparatus, a controller performs acceleration control of an own vehicle, based on an actual inter-vehicle physical quantity and a target inter-vehicle physical quantity. A limiter sets a limit value for a target jerk during the acceleration control. A detector detects an occurrence of at least one of: an event in which the inter-vehicle distance becomes discontinuously shorter; and an event in which a target inter-vehicle distance corresponding to the target inter-vehicle physical quantity becomes discontinuously longer. A determiner determines a risk of collision with the preceding vehicle, based on an operation state of the preceding vehicle in relation to the own vehicle. When at least one of the events is detected, the limiter sets the limit value to a value based on the risk of collision such that change in deceleration of the own vehicle is kept lower as the risk of collision decreases.

  • Patent number: 9919599
    Abstract: A terminal detection unit detects a mobile terminal located inside a vehicle. An action history information generation unit and storage unit associate the mobile terminal detected by the terminal detection unit and an action of the vehicle associated with each other and store them as action history information. An action suggestion unit searches the action history information stored in the storage unit for the action associated with the mobile terminal detected by the terminal detection unit and suggests the found action to a passenger of the vehicle.

  • Patent number: 9878710
    Abstract: The invention regards a method for improving performance of a method for computationally predicting a future state of a target object, a driver assistance system and a vehicle with such driver assistance system. First data describing a traffic environment including a target object is acquired. On the basis of the acquired data at least one prediction step for estimating a future state of an object in the traffic environment is performed and a signal indicative of a prediction result describing an estimated future state of the target object and/or an ego vehicle is generated. An actual state of the target object and/or the ego vehicle is observed and quality of the prediction by comparing the observed actual state and the prediction result is estimated. Finally the prediction result and/or parameters of the prediction algorithm is adapted.

  • Patent number: 9874634
    Abstract: A radar apparatus derives (i) first target information of a first target existing in the transmission range of the transmission wave, the first target being a rear end portion of a vehicle and (ii) second target information of a second target existing in the transmission range of the transmission wave, the second target being a portion of the vehicle other than the rear end portion of the vehicle. The radar apparatus calculates a distance difference between the first target and the second target, and predicts, in a case where the first target information of the first target derived in a previous target information derivation process is not derived in a latest target information derivation process, a position of the first target, using the distance difference and the second target information of the second target derived in the latest target information derivation process.

  • Patent number: 9845093
    Abstract: A vehicle speed limiting apparatus includes an opening detection unit to detect an opening of an accelerator pedal of the vehicle; an estimation unit to estimate whether the vehicle starts a lane change; and an ECU to implement an upper-limit setting unit to set an upper-limit speed of the vehicle, a vehicle speed control unit to control the traveling speed so as not to exceed the upper-limit speed even when the opening of the accelerator pedal becomes great enough to make the traveling speed exceed the upper-limit speed, and a permissible speed setting unit to set a permissible speed higher than the upper-limit speed. When the estimation unit estimates that the vehicle starts the lane change, the vehicle speed control unit permits the traveling speed to exceed the upper-limit speed, and controls the traveling speed so as not to exceed the permissible speed.

  • Patent number: 9783197
    Abstract: A trajectory tracking control unit carries out a trajectory tracking control in the event that a predetermined condition is satisfied. On the other hand, in the case that a preceding vehicle recognizing unit detects that a preceding vehicle has moved in a vehicle transverse direction, the trajectory tracking control unit predicts that the preceding vehicle will depart from a lane in which it is traveling. Therefore, even if the predetermined condition is satisfied after the preceding vehicle recognizing unit has detected that the preceding vehicle has moved in the vehicle transverse direction, the trajectory tracking control unit does not cause the driver's own vehicle to follow the trajectory of the preceding vehicle.

  • Patent number: 9776634
    Abstract: A method for operating a speed control system of a vehicle having a plurality of wheels is provided. The method comprises receiving one or more electrical signals representative of vehicle-related information. The method further comprises determining, based on the one or more electrical signals representative of vehicle-related information, that one or more of the wheels of the vehicle have overcome an obstacle or are about to overcome an obstacle and that therefore a reduction in an applied drive torque to one or more of the wheels of the vehicle by a powertrain subsystem (applied drive torque) will be required to maintain the speed of the vehicle at a target set-speed of the speed control system. The method still further comprises automatically commanding the application of a retarding torque to one or more of the wheels of the vehicle to counteract the effect of an overrun condition in the powertrain subsystem from increasing the speed of the vehicle.
