  • Publication number: 20240103527
    Abstract: An acquisition processing part acquires a captured image from a camera which is installed on a work vehicle. A detection processing part detects an obstacle on the basis of the captured image which is acquired by the acquisition processing part. When an obstacle is detected by the detection processing part, a reception processing part receives a traveling stop instruction for stopping automatic traveling of the work vehicle or a traveling continuation instruction for continuing automatic traveling of the work vehicle. A traveling processing part stops the automatic traveling of the work vehicle when the reception processing part receives the traveling stop instruction, and continues the automatic traveling of the work vehicle when the reception processing part receives the traveling continuation instruction.

  • Publication number: 20240042997
    Abstract: A travel control apparatus for a vehicle includes a surrounding environment recognition device, a collision time calculator, a collision object estimator, an after-collision travel range estimator, a collision detector, and a travel control unit. The surrounding environment recognition device includes a recognizer, a collision object recognizer that recognizes an object that has a possibility to come into collision with the vehicle, and a safety degree region setter that sets safety degree regions. The collision object estimator estimates a travel route of the object and a collision position on the vehicle. The after-collision travel range estimator estimates a travel range of the vehicle after the collision based on the estimated collision position. When the collision between the vehicle and the object is detected, the travel control unit performs travel control depending on a safety degree in one of the safety degree regions in front of the travel range after the collision.

  • Publication number: 20240023473
    Abstract: An acquisition processing part acquires detection information from a first obstacle sensor which detects an obstacle in a first detection area, and a second obstacle sensor which detects an obstacle in a second detection area. When an obstacle is detected in the first detection area, a traveling processing part executes travel restriction of a work vehicle. When the obstacle enters a non-detection area from the first detection area in a state in which the work vehicle is under the travel restriction, a determination processing part determines whether or not the obstacle further enters the second detection area from the non-detection area. When it is determined that the obstacle enters the second detection area from the non-detection area, the traveling processing part continues the travel restriction of the work vehicle.
