  • Publication number: 20210362716
    Abstract: A driving assistance device includes a guide line detecting unit, a remaining distance acquiring unit, and a braking control unit. The guide line includes a base-point mark which is provided at a position which is separated a first distance from the scheduled stop position. The guide line detecting unit detects the base-point mark at a measurement position of a captured image and sets the detected position of the base-point mark at the measurement position of the captured image as the center of the base-point mark in an extending direction of the guide line when the base-point mark is detected at the measurement position of the captured image. The remaining distance acquiring unit acquires the remaining distance on the basis of the position of the base-point mark set by the guide line detecting unit.

  • Publication number: 20210304618
    Abstract: A convoy travel system includes a plurality of vehicles and is configured such that the plurality of vehicles form a convoy and travel. The plurality of vehicles include a preceding vehicle and following vehicles configured so as to follow the preceding vehicle by means of automatic driving. The preceding vehicle is equipped with a steering information acquisition unit configured so as to acquire steering information pertaining to steering of the preceding vehicle, and a transmission unit configured so as to transmit the steering information to the following vehicles. The following vehicles are equipped with a reception unit configured so as to receive the steering information, and an automatic driving control unit configured so as to begin a steering angle control for avoiding a collision with an obstruction when the steering information indicates the execution of emergency steering for avoiding a collision with the obstruction.

  • Publication number: 20210245759
    Abstract: A travel assistance device configured to execute travel assistance when a plurality of vehicles form a vehicle group and travel in a line. The travel assistance device includes: a first control unit configured to, if there is lane-change instruction for the vehicle group, cause an end-of-line vehicle to change lanes, such vehicle being the vehicle from among the plurality of vehicles forming the vehicle group that is positioned at the end of the line; and a second control unit configured to, following the lane change of the end-of-line vehicle, allow a lane change for at least one vehicle that is other than the end-of-line vehicle and that is one of the vehicles forming the vehicle group.

  • Publication number: 20210240201
    Abstract: A platooning system includes a vehicle control system installed in each of vehicles that include a manually-driven head vehicle. The vehicle control system controls a host vehicle such that the host vehicle follows a lead vehicle through wireless communication between the host vehicle and the lead vehicle. The vehicle control system is installed in the host vehicle and the lead vehicle. The vehicle control system includes a sensor that detects a state of the host vehicle, an actuator that adjusts a behavior of the host vehicle, and a controller that controls the host vehicle. The controller of the head vehicle physically notifies a driver of the host vehicle of a state of a subsequent vehicle by operating the actuator of the host vehicle when a state signal including information that indicates the state of the subsequent vehicle is received through the wireless communication.

  • Publication number: 20210163006
    Abstract: A driving assistance device includes a guide line detecting unit configured to detect the guide line, a remaining distance acquiring unit configured to acquire a remaining distance to the scheduled stop position, and a braking control unit configured to control deceleration of a vehicle. The guide line detecting unit detects a base-point mark, a curvature of the guide line, and a curvature feature point. The remaining distance acquiring unit acquires the remaining distance on the basis of the position of the base-point mark when the guide line detecting unit has detected the base-point mark, and acquires the remaining distance on the basis of the position of the curvature feature point when the guide line detecting unit has not detect the base-point mark and has detected the curvature feature point.

  • Patent number: 7010408
    Abstract: Fuel consumption due to abrupt acceleration is reduced. An auto-cruising control is automatically started without intention of a driver and executes a control for gently and reasonably accelerating a vehicle even when an accelerator pedal is displaced abruptly. When a regular running state is detected, the auto-cruising control is started automatically. When the auto-cruising control is effective and the accelerator pedal is displaced substantially, fuel consumption is restricted by setting an aimed vehicle speed stepwise with small speed change, so that a large amount of fuel is not supplied.
