Abstract

Disclosed is a control system mounted on a first movable body. The control system has a sensor recognizing a peripheral object of the first movable body, a processor connected to the sensor, and an output device connected to the processor. The processor estimates safety of overtaking of the first movable body by a second movable body moving at the back of the first movable body, on the basis of information acquired from the sensor, and the processor outputs an estimation result of the safety to the second movable body via the output device.

First claim

What is claimed is:

1. A control system mounted on a first movable body, comprising:
a sensor recognizing a peripheral object of the first movable body;
a processor connected to the sensor; and
a first output device connected to the processor, wherein
the processor estimates safety of overtaking of the first movable body by a second movable body moving at the back of the first movable body, on the basis of information acquired from the sensor, and
the processor outputs an estimation result of the safety to the second movable body via the first output device, wherein
when it is estimated that overtaking of the first movable body by the second movable body is not safely performed, the processor controls the movement of the first movable body so that overtaking of the first movable body by the second movable body becomes difficult.

2. The control system according to claim 1 , wherein
the first movable body and the second movable body are vehicles traveling on a road, and
when it is estimated that overtaking of the first movable body by the second movable body is not safely performed, the processor controls the movement of the first movable body so that the first movable body travels at a position closer to an opposite lane than a center of a lane.

3. The control system according to claim 1 , further comprising: a second output device connected to the processor, wherein
the first movable body and the second movable body are vehicles traveling on a road, and
when it is estimated that overtaking of the first movable body by the second movable body is not safely performed, the processor outputs information recommending that the first movable body travels at a position closer to an opposite lane than a center of a lane to a driver of the first movable body, via the second output device.

4. The control system according to claim 1 , wherein
when it is estimated that overtaking of the first movable body by the second movable body is safely performed, the processor controls the movement of the first movable body so that overtaking of the first movable body by the second movable body becomes easy.

5. The control system according to claim 1 , wherein
the first movable body and the second movable body are vehicles traveling on a road, and
when it is estimated that overtaking of the first movable body by the second movable body is safely performed, the processor controls the movement of the first movable body so that the first movable body travels at a position farther from an opposite lane than a center of a lane and decelerates.

6. The control system according to claim 1 , further comprising: a second output device connected to the processor, wherein
the first movable body and the second movable body are vehicles traveling on a road, and
when it is estimated that overtaking of the first movable body by the second movable body is safely performed, the processor outputs information recommending that the first movable body travels at a position farther from an opposite lane than a center of a lane and decelerates to a driver of the first movable body, via the second output device.

7. A control system mounted on a first movable body, comprising:
a sensor recognizing a peripheral object of the first movable body;
a processor connected to the sensor; and
a first output device connected to the processor, wherein
the processor estimates safety of overtaking of the first movable body by a second movable body moving at the back of the first movable body, on the basis of information acquired from the sensor,
the processor outputs an estimation result of the safety to the second movable body via the first output device,
the first output device is a display device displaying a character or an image showing the estimation result of the safety, wherein
the processor specifies a position relation between the first movable body and the second movable body, on the basis of the information acquired from the sensor, and
the processor controls the movement of the first movable body so that the position relation between the first movable body and the second movable body becomes a position relation where the display device is easily viewed by a driver of the second movable body, on the basis of the specified position relation.

8. The control system according to claim 7 , wherein
the processor controls the display device so that the display device is easily viewed by a driver of the second movable body, on the basis of the information acquired from the sensor,
the display device has a drive device adjusting a direction of a screen of the display device,
the processor specifies a position relation between the first movable body and the second movable body, on the basis of the information acquired from the sensor, and
the processor controls the drive device so that the screen of the display device is oriented in a direction where the screen is easily viewed by the driver of the second movable body, on the basis of the specified position relation.

9. The control system according to claim 8 , wherein
the sensor includes a sensor detecting a surrounding brightness of the first movable body and
the processor controls the display device so that a brightness of the screen of the display device is matched with the surrounding brightness of the first movable body, on the basis of the information acquired from the sensor.

10. The control system according to claim 7 , wherein
the first output device is an audio output device outputting audio showing the estimation result of the safety.
