Description

  The present invention relates to an object detection display device that detects an object around a vehicle and displays the information to a driver.

  In recent years, in order to prevent collisions with obstacles when parking, starting, or traveling, sensors for detecting objects are provided at various locations on the vehicle, and information detected by the sensors is displayed to the driver. A device for warning the driver is mounted on the vehicle.

  For example, Patent Document 1 discloses what kind of event is occurring based on information obtained by an external sensor that detects an obstacle and a vehicle outside the vehicle, and an internal sensor that detects vehicle failure and tire puncture. An alarm device for a vehicle is disclosed in which an indicator attached to a rear-view mirror blinks and emits an alarm sound depending on whether it is, in which direction, or to what extent.

JP 2006-44295 A

  In the technique of Patent Document 1, information detected by an external sensor and an internal sensor is displayed on the rearview mirror. However, when starting the vehicle, the driver often watches the side mirror on the driver's seat side. There is a possibility that the driver will start without noticing even if an abnormality is displayed on the screen.

  Especially in large vehicles such as buses and trucks, the rear of the vehicle may not be confirmed by the rearview mirror, and the driver mainly monitors the situation around the vehicle by the side mirror. However, large vehicles have more blind spots than passenger cars because the driver's line of sight is high from the ground and the vehicle body is large. In particular, in the case of buses, there is a passenger entrance / exit on the side opposite to the driver's side, so people who get off the bus cannot be confirmed with the side mirror on the driver's side. There is a risk that the vehicle will start without the driver being aware that there are people around the vehicle.

  The present invention has been made to solve such a problem, and the object of the present invention is to make it possible for the driver to easily check objects around the vehicle when starting, and to start the vehicle more safely. Another object is to provide an object detection display device capable of performing the above.

  Each of the laser sensors 10 to 19 is a sensor that can detect the position and distance of an object by irradiating a laser from the position where it is provided toward the outside of the vehicle and detecting the reflection. In FIG. 2, a horizontal range in which an object is detected by each of the laser sensors 10 to 19 is indicated by a dotted line.

  Further, an alarm device 20 that emits a warning sound to the driver is provided in the driver's seat.

  Here, FIG. 3 shows a front view of the right side mirror on the driver's seat side. Hereinafter, the configuration of the right side mirror 3R will be described in detail with reference to FIG.

  In the right side mirror 3R, a mirror surface portion 22 having the same shape is held inside a substantially rectangular housing 21 that is long in the vertical direction. In the housing 21, a plurality of light emitting portions (display means) 23 to 27 are disposed on the peripheral edge portion 21 a on the outer peripheral side of the mirror surface portion 22. Specifically, in the peripheral part 21a, the upper right light emitting part 23 at the upper right side, the upper left light emitting part 24 at the upper left part, the left middle light emitting part 25 at the central left part, the lower left light emitting part 26 at the lower left part, and the lower right light emission at the lower right part. A portion 27 is provided. Each light emission part 23-27 is an LED light, for example.

  The light emitting units 23 to 27 are associated with the laser sensors 10 to 19, respectively. In the present embodiment, the upper right light emitting unit 23 is the front right angle laser sensor 10 and the front right laser sensor 11, and the upper left light emitting unit 24 is the front left. The laser sensor 12 and the left front corner laser sensor 13, the left middle light emitting unit 25 at the front door laser sensor 14 and the middle door laser sensor 15, the lower left light emitting unit 26 at the left rear corner laser sensor 16 and the left rear laser sensor 17, The lower light emitting unit 27 is associated with the right rear laser sensor 18 and the right rear corner laser sensor 19, respectively. That is, the light emitting units 23 to 27 are arranged at positions corresponding to the arrangement of the laser sensors 10 to 19 in the right side mirror 3R. The light emitting units 23 to 27 associated with the laser sensors 10 to 19 emit light when an object is detected by the corresponding laser sensors 10 to 19, thereby displaying that the object is detected.

  The alarm device 20 is also associated with each of the laser sensors 10 to 19 and issues an alarm when an object is detected by any of the laser sensors 10 to 19.

  The light emitting units 23 to 27 and the alarm device 20 change the display and alarm modes according to the distance between the object detected by the corresponding laser sensors 10 to 19 and the vehicle 1, that is, according to the degree of danger. Also good. For example, the light emitting units 23 to 27 may change the emission color, such as changing the color from yellow to red as the object is closer to the vehicle 1. In the case of a single emission color, it may be turned on from flashing according to the distance to the object. The alarm device 20 may increase the volume of the alarm sound or issue an alarm message as the object is closer to the vehicle 1.

  As described above, the object detection display device according to this embodiment includes the laser sensors 10 to 19 provided in the vehicle 1, the light emitting units 23 to 27 of the right side mirror 3 </ b> R associated with the laser sensors 10 to 19, and the alarm device 20. It is configured.

  Hereinafter, the operation of the object detection display device of the present embodiment will be described.

  For example, when the vehicle 1 is stopped on the shoulder on the left side in the traveling direction with respect to the road, the vehicle 1 enters the road by moving to the right side when starting from there. The right side mirror 3R is watched for monitoring. At this time, for example, when a passenger gets off from the middle door 5 of the vehicle 1 before starting and is present around the middle door 5 even at the time of starting, the passenger is detected by the inner door laser sensor 15. . Then, the left middle light emitting portion 25 of the right side mirror 3R associated with the middle door laser sensor 15 is turned on and an alarm sound is emitted from the alarm device 20.

  As a result, the driver can recognize that there is an object around the vehicle 1 by the alarm sound, and confirm that the left middle light emitting portion 25 of the right side mirror 3R is lit, so that the middle door 5 It is possible to recognize that there is an object in the vicinity.

  As described above, according to the object detection display device of the present embodiment, information indicating that an object has been detected by each of the laser sensors 10 to 19 is detected on the right side mirror 3R that the driver gazes at the time of departure. Since the light emitting units 23 to 27 corresponding to the positions are displayed by light emission, the driver can grasp the situation around the vehicle without moving the line of sight greatly. In addition, the alarm sound is emitted by the alarm device 20 so that the driver can be surely recognized that there is an object around the vehicle.

  Furthermore, when the display and alarm modes of the light emitting units 23 to 27 and the alarm device 20 change according to the degree of danger, the driver can more accurately grasp the position of the object with respect to the vehicle.

  From the above, the driver can easily check objects around the vehicle at the time of start, and the vehicle can be started more safely.

  This is the end of the description of the embodiment of the object detection display device according to the present invention, but the embodiment is not limited to the above embodiment.
