  • Publication number: 20200363817
    Abstract: An autonomous moving apparatus control system including a range sensor, a reflection plate, and a control unit. The range sensor is installed in a cage of an elevator and detects a distance to an object by receiving reflected light of signal light applied to the object. The reflection plate is disposed in an elevator hall of a floor on which the elevator stops, and reflects the signal light. The control unit determines whether or not a mobile robot, which is an autonomous moving apparatus, can get on and off the elevator based on a detected distance, the detected distance being a distance to the reflection plate detected by the range sensor.

  • Patent number: 10160317
    Abstract: A vehicle's accelerator pedal depression amount is detected; a speed limit of a road on which the vehicle is traveling is determined; a start of a lane change is estimated; an upper-limit speed is determined each time when the speed limit changes; and the travelling speed is controlled to not exceed the upper-limit speed even if the accelerator pedal depression amount increases to cause the speed of the vehicle to exceed the upper-limit speed. The speed of the vehicle is controlled, until a predetermined timing, to not exceed the upper-limit speed determined before the start of a lane change is estimated, if (i) the start of a lane change is estimated, and (ii) a reduction in the speed limit is determined. After the predetermined timing, the speed of the vehicle is controlled to not exceed the currently determined upper-limit speed.

  • Patent number: 10046763
    Abstract: A control system for a vehicle includes an imaging device; a co-ECU to limit the travel speed of the vehicle; and an ECU to set the speed limit, that recognizes the speed limit value on a road while traveling, and sets the recognized speed limit value in the co-ECU. If the elapsed time since the speed limit value has been set reaches a predetermined time, the ECU estimates the speed limit value on the road while traveling, and if receiving a switch command, switches the speed limit value set in the co-ECU to the estimated speed limit value so as to avoid limiting the vehicle speed by a speed limit value that is different from the actual speed limit value on the road.

  • Patent number: 9988050
    Abstract: A vehicle control device which can substantially eliminate or shorten a period when vehicle speed exceeds a lowered speed limit when a vehicle goes into a road where a speed limit lower than before then during running of the vehicle should be provided. A speed control decreases vehicle speed so that the vehicle speed approaches the next speed limit from a time point when it is judged that a position of the own-vehicle is at a predetermined position in front of a transition point which is a point where the next speed limit starts to be applied, in a case where a specified condition that the next speed limit is lower than the present speed limit is satisfied.

  • Patent number: 9733642
    Abstract: A vehicle control device is capable of switching a driving state of a host vehicle between manual driving and autonomous driving, and determines whether or not another vehicle exists in a driver's blind area set in advance diagonally behind the host vehicle in a case where the driving state of the host vehicle is autonomous driving and when the host vehicle reaches a check timing set in advance. In addition, the vehicle control device executes the control in a case where it is determined that the other vehicle exists in the driver's blind area and when the other vehicle exists, which can be removed from the driver's blind area by the control of at least one of a vehicle speed of the host vehicle and a lateral position of the host vehicle.
