  • Publication number: 20210245753
    Abstract: There is provided a travel control apparatus. A control unit controls a position of the self-vehicle in a width direction so as to ensure a first predetermined interval between the self-vehicle and the other vehicle and to ensure a second predetermined interval between the self-vehicle and the boundary of the first lane. In a case in which both the first predetermined interval and the second predetermined interval cannot be ensured, the control unit controls the position of the self-vehicle in the width direction to preferentially ensure the first predetermined interval when the other vehicle has crossed a first boundary between the first lane and the second lane and to preferentially ensure the second predetermined interval when the other vehicle has not crossed the first boundary.

  • Publication number: 20210171065
    Abstract: In an autonomous driving vehicle information presentation apparatus, an interference area setting unit sets an interference area on a scheduled travel route for a host vehicle based on an action plan for the host vehicle. A prediction unit predicts behavior of traffic participants with respect to the host vehicle based on the outside information. An extraction unit extracts, based on the interference area and the behavior of the traffic participants predicted by the prediction unit, a specific traffic participant among the traffic participants which is currently present in the interference area or expected to enter the interference area. An information presentation unit presents information on the action plan for the host vehicle to the specific traffic participant extracted by the extraction unit as a presentation target.

  • Publication number: 20210171060
    Abstract: In an autonomous driving vehicle information presentation apparatus, an estimation unit estimates a scheduled path for a host vehicle M. A prediction unit predicts a scheduled path for traffic participants. Based on the scheduled path for the host vehicle and the scheduled path for the traffic participants, an interference determination unit determines whether these two scheduled paths will interfere with each other in a predetermined time period. If the two scheduled paths will interfere with each other in the predetermined time period, an extraction unit extracts a specific traffic participant to be involved in the interference among the traffic participants. An information presentation unit presents information for avoiding the interference to the specific traffic participant extracted by the extraction unit as a presentation target.

  • Publication number: 20210170943
    Abstract: In an autonomous driving vehicle information presentation apparatus, based on outside information, an identification unit searches for a person present around a host vehicle and identifies whether the person extracted by the search matches a user of the host vehicle. When a result of the identification by the identification unit indicates that the person extracted by the search matches the user of the host vehicle, the information presentation unit presents information by using a preset presenting state to a specific person, as a presentation target, identified to match the user of the host vehicle by the identification unit with an exterior display apparatus provided at a front portion of the host vehicle.

  • Publication number: 20210170942
    Abstract: In an autonomous driving vehicle information presentation apparatus, an outside information obtaining unit obtains outside information on an outside including a trailing vehicle present behind a host vehicle in a direction of advance. A determination unit determines presence of the trailing vehicle following the host vehicle, based on the outside information. A calculation unit 325 calculates a host vehicle-trailing vehicle distance being a distance between the host vehicle and the trailing vehicle when the determination unit determines that the trailing vehicle following the host vehicle is present. An information presentation unit presents information addressed to the trailing vehicle by using a rear display unit provided in a rear portion of a cabin of the host vehicle.

  • Publication number: 20200081436
    Abstract: A device for generating a policy for determining a path in automated driving of a vehicle, comprises a compensation estimator; and a processing unit for generating a policy so as to increase an expected value of compensation obtained by inputting a situation surrounding a vehicle and an action of the vehicle to the estimator. The processing unit generates an intermediate policy through reinforcement, determines an action that a vehicle is to take by applying the intermediate policy to an actual surrounding situation of a driver, determines whether an error between the determined action and an actual action by the driver is smaller than or equal to a threshold. If the error is larger than the threshold, compensation of the estimator is updated and the intermediate policy is determined again. Otherwise, the intermediate policy is set as the policy.

  • Patent number: 10162361
    Abstract: A steering control unit performs lane keeping control to cause a steering system to operate to reduce a distance between a width-direction center position of a lane and a position where the vehicle is traveling in the lane on the basis of a recognized state of the lane obtained by a lane recognizing unit. A road condition determining unit determines whether the road on which the vehicle is traveling is a straight road. A lane keeping responsivity setting unit sets, when it is determined by the road condition determining unit that the road on which the vehicle is traveling is a straight road, responsivity of the lane keeping control to the distance to be lower than responsivity set when it is determined that the road on which the vehicle is traveling is not a straight road.
