When the host vehicle performs an operation for turning on the right turn signal during execution of auto-cruise control (hereinafter also referred to as ACC) for controlling the traveling speed so as to keep the inter-vehicle distance from the preceding vehicle constant. Three seconds later, automatic overtaking or lane change is performed. In order to overtake the preceding vehicle, automatic overtaking first moves to the right lane by automatic driving.After passing the preceding vehicle, the driver performs an operation to turn on the left turn signal. Traveling to the left lane. The lane change is a travel in which an automatic driving first moves to the right lane to overtake the preceding vehicle and maintains the current lane even after overtaking the preceding vehicle.

  The HUD device 2 irradiates display light for displaying an image from below the windshield toward the windshield. As a result, the driver visually recognizes the projected virtual image superimposed on the actual scenery in front of the vehicle. The HUD device 2 displays an image on a rectangular display screen region DR provided below the windshield (see FIG. 2).

The left rear camera 3 is installed at the left end portion of the vehicle and captures the situation of the left rear of the vehicle.
The right rear camera 4 is installed at the right end of the vehicle, and photographs the situation on the right rear side of the vehicle.
The electronic mirror 5 is a display device installed on the left and right sides of the dashboard (see FIG. 2). The electronic mirror 5 installed on the left side displays an image captured by the left rear camera 3, and the electronic mirror 5 installed on the right side displays an image captured by the right rear camera 4.

  The radar device 6 includes at least one of a millimeter wave radar device and a laser radar device. The radar device 6 transmits a radar wave toward the periphery of the vehicle and receives a reflected radar wave, so that the radar device 6 is positioned around the vehicle. The position of the vehicle to be operated (hereinafter also referred to as a surrounding vehicle) and the relative speed between the host vehicle and the surrounding vehicle are detected.

The vehicle speed sensor 7 detects the traveling speed of the host vehicle.
The navigation device 8 acquires road map data from a map storage medium in which road map data and various types of information are recorded, and based on a GPS signal received via a GPS (Global Positioning System) antenna (not shown) or the like. It is configured to detect the current position. The navigation device 8 is configured to execute control for displaying the current location of the vehicle on the display screen ND (see FIG. 2), control for guiding a route from the current location to the destination, and the like. Yes.

  The control unit 9 is mainly configured by a known microcomputer including a CPU, a ROM, a RAM, an I / O, a bus line connecting these components, and the like. The control unit 9 executes various processes based on inputs from the cameras 3 and 4, the radar device 6, the vehicle speed sensor 7, and the navigation device 8, and controls the HUD device 2, the electronic mirror 5, and the navigation device 8.

In the vehicle information providing apparatus 1 configured as described above, the control unit 9 executes an information providing process described later.
First, the procedure of the information provision process which the control part 9 performs is demonstrated. The information providing process is a process that is repeatedly executed during the operation of the vehicle information providing apparatus 1.

  When this information providing process is executed, as shown in FIG. 3, the control unit 9 first determines the own vehicle based on the traveling speed detected by the vehicle speed sensor 7 (hereinafter referred to as the own vehicle traveling speed) in S10. A current speed image VP indicating the traveling speed (see FIG. 4A) is displayed on the HUD device 2. The current speed image VP of the present embodiment is an image showing the traveling speed of the host vehicle in numbers and units.

Next, in S20, the surrounding situation of the host vehicle is detected. Specifically, the position of the surrounding vehicle and the relative speed between the host vehicle and the surrounding vehicle are detected by the radar device 6.
In S30, it is determined whether or not the host vehicle is executing ACC. Here, when ACC is not being executed (S30: NO), the information providing process is temporarily ended. On the other hand, if the ACC is being executed (S30: YES), it is determined in S40 whether or not the host vehicle is being automatically overtaken or changing the lane. Here, when the vehicle is not automatically overtaking and the vehicle line is not being changed (S40: NO), it is determined at S50 whether or not the host vehicle catches up with the preceding vehicle based on the detection result at S20. . Specifically, for example, based on the distance and relative speed between the host vehicle and the preceding vehicle, the time until the host vehicle catches up with the preceding vehicle is set to a display determination time (for example, 20 seconds in the present embodiment) or less. If it is, it is determined that the host vehicle catches up with the preceding vehicle.

  If it is determined that the host vehicle catches up with the preceding vehicle (S50: YES), the process proceeds to S70. On the other hand, if it is determined that the host vehicle cannot catch up with the preceding vehicle (S50: NO), the current position information indicating the current position of the host vehicle and the planned travel route of the host vehicle are obtained from the navigation device 8 in S60. By acquiring the information shown and the road map data around the current position, it is determined whether or not the host vehicle is approaching an intersection having a straight lane and a right / left turn lane and the host vehicle is making a right turn. If the host vehicle is approaching an intersection having a straight lane and a right / left turn lane and the host vehicle turns right (S60: YES), the process proceeds to S70. On the other hand, if the vehicle is not approaching an intersection having a straight lane and a right / left turn lane, or if the host vehicle does not turn right at the approaching intersection (S60: NO), the process proceeds to S90.

  Then, when the process proceeds to S70, it is determined whether or not the own vehicle is in a situation where the vehicle can be automatically overtaken or the vehicle line can be changed based on the detection result in S20. Specifically, for example, when there is no vehicle approaching the host vehicle from the rear of the host vehicle (hereinafter referred to as an approaching rear vehicle), or until the host vehicle performs automatic overtaking or lane change If the vehicle does not catch up with the host vehicle, it is determined that the host vehicle is in a situation where it can be automatically overtaken or a vehicle line can be changed.

  Here, when the vehicle is in a situation where the vehicle can be automatically overtaken or the vehicle line can be changed (S70: YES), in S80, a preset start timing image (FIGS. 4, 7, and 8 ( b) is displayed on the HUD device 2. On the other hand, if the vehicle is not in a situation where it can be automatically overtaken or changed to an automobile line (S70: NO), the information providing process is temporarily terminated.

  In S90, it is determined whether or not an operation for turning on the right turn signal has been performed. Here, when an operation to turn on the right turn signal is performed (S90: YES), in S100, based on the detection result in S20, a preset lane change possibility image (FIG. 12B). ), (C) and FIG. 13B) are displayed on the HUD device 2, and the information providing process is temporarily terminated.

  On the other hand, when the operation to turn on the right turn signal is not performed (S90: NO), based on the detection result in S20 and the road map data around the current position acquired from the navigation device 8 in S110. Thus, it is determined whether or not the traveling speed of the preceding vehicle is significantly slower than the speed limit of the traveling road. Here, when the traveling speed of the preceding vehicle is extremely slow (S110: YES), in S120, a preset lane change confirmation image (see FIG. 13D) is set based on the detection result in S20. ) Is displayed on the HUD device 2, and the information providing process is temporarily terminated. On the other hand, when the traveling speed of the preceding vehicle is not extremely slow (S110: NO), a pre-set ACC image (see FIG. 10A) is sent to the HUD device 2 in S130. The information providing process is temporarily terminated.

  In S40, if the vehicle is in the process of being automatically overtaken or changing lanes (S40: YES), a preset lane changing image is displayed in S140 (see FIG. 10D). 11) is displayed on the HUD device 2, and the information providing process is temporarily terminated.
