Abstract

[Problem] To suppress the feeling that the display on the screen is bothersome to the viewer of the image. [Solution] The display control unit displays an image on the display unit as a lane image representing the lane in which the vehicle is traveling, which includes a straight section 70 located on the near side from the viewer's perspective and fixed in a straight line, a curved section 72 located further back than the straight section 70 and curved in a curved shape according to the curve of the lane, and a reverse curved section 74 between the straight section 70 and the curved section 72 that is curved in the opposite direction to the curved section 72.

Claims (3)

  1. A display control device including a display unit that displays an image on a display unit representing the vehicle's own lane, which includes a straight section located closer to the viewer and fixed in a straight line, and a curved section located further back than the straight section and curved in a curved manner according to the curve of the vehicle's lane.
  2. The display control device according to claim 1, wherein the display control unit overlays the image of the vehicle representing the vehicle onto the image of the lane, and extends the straight section of the lane image beyond the display position of the vehicle image.
  3. The display control device according to claim 1, wherein the display control unit displays an image of the current lane, in which a reverse curved section is provided between the straight section and the curved section, curved in the opposite direction to the curved section.

Description

This disclosure relates to a display control device. Patent Document 1 discloses that the display area V3 of a head-up display device displays an image corresponding to the surrounding road on which the vehicle is traveling, and a mark M1 indicating the vehicle's position (see paragraph "0059" and Figure 4 of Patent Document 1). In particular, Figure 4 of Patent Document 1 shows a state in which the "image corresponding to the surrounding road on which the vehicle is traveling" is curved to the left from the closest position to the vehicle occupant, corresponding to a leftward curve in the road. Japanese Patent Publication No. 2023-045138 This is a block diagram showing the schematic configuration of an in-vehicle system according to an embodiment.This is a flowchart showing an example of the process for generating an image of the current lane.This is an illustrative diagram showing an example of an image of the current lane.This is an illustrative diagram showing an example of an image displayed on the display unit.This is an illustrative diagram showing other examples of images displayed on the display unit. Hereinafter, an example of an embodiment of this disclosure will be described in detail with reference to the drawings. As shown in Figure 1, the in-vehicle system 10 according to this embodiment includes a communication bus 12. The communication bus 12 is connected to a group of surrounding situation acquisition devices 14, a group of vehicle driving state detection sensors 26, a target recognition ECU (Electronic Control Unit) 60, an ADAS (Advanced Driver-Assistance Systems) ECU 34, and a display control ECU 42, respectively. Note that Figure 1 shows only a part of the in-vehicle system 10. Furthermore, in the following, the vehicle on which the in-vehicle system 10 is installed will be referred to as "the vehicle." The surrounding environment acquisition device group 14 includes devices that acquire information representing the conditions of the surrounding environment of the vehicle, such as a GNSS (Global Navigation Satellite System) device 16, an in-vehicle communication device 18, a navigation system 20, a radar device 22, and a camera unit 24. The GNSS device 16 receives GNSS signals from multiple GNSS satellites to determine the vehicle's position. The on-board communication device 18 performs at least one of vehicle-to-vehicle communication with other vehicles and vehicle-to-infrastructure communication with roadside units. The navigation system 20 includes a map information storage unit 20A that stores map information. Based on the position information obtained from the GNSS device 16 and the map information stored in the map information storage unit 20A, it displays the vehicle's position on a map and determines and guides the vehicle to its destination. The radar device 22 detects objects such as other vehicles and pedestrians in the vicinity of the vehicle as point cloud information, and acquires the relative position and relative speed of the detected objects and the vehicle. Furthermore, based on changes in the relative position and relative speed of individual objects, the radar device 22 excludes noise, roadside objects such as guardrails, etc., from the monitoring target, and outputs information such as the relative position and relative speed of the monitored objects (targets) such as other vehicles and pedestrians. The camera unit 24 captures images of the vehicle's surroundings with multiple cameras and outputs the captured images. Furthermore, the vehicle driving state detection sensor group 26 includes, as multiple sensors for acquiring the vehicle's driving state, a steering angle sensor 28 for detecting the vehicle's steering angle, a vehicle speed sensor 30 for detecting the vehicle's speed, and an acceleration sensor 32 for detecting the acceleration applied to the vehicle. The target recognition ECU 60, although not shown in the diagram, incorporates a CPU (Central Processing Unit), memory such as ROM (Read Only Memory) and RAM (Random Access Memory), and storage such as an HDD (Hard Disk Drive) and SSD (Solid State Drive). The storage contains a predetermined program that enables the CPU of the target recognition ECU 60 to function as the target recognition unit 62. The target recognition unit 62 recognizes the boundary line of the lane the vehicle is traveling in (the vehicle's own lane) from the image of the area in front of the vehicle captured by the camera unit 24. This lane recognition also recognizes whether the vehicle's own lane is curved, and if it is curved, it also recognizes the turning direction and radius of curvature. The object recognition unit 62 also recognizes objects around the vehicle (such as vehicles traveling in the vehicle's own lane or adjacent lanes) in the image captured by the camera unit 24, recognizes the type of object (e.g., whether it's a passenger car or a large vehicle), and detects and outputs the distance between the vehicle and the
