Description

This invention relates to a vehicle operation schedule notification device and a vehicle operation schedule notification method. Conventionally, it is known that a driver can indicate their intention to change lanes to those around them using projected text, arrows, or sound, and that they can express their gratitude to drivers of surrounding vehicles who allow them to cut in (Patent Document 1). Japanese Patent Publication No. 2019-051822 This is a schematic diagram showing the configuration of the vehicle's installed action plan notification system.This is a schematic diagram showing the functional blocks of the ECU processor installed in the vehicle.This is a schematic diagram illustrating how a vehicle travels from its starting point to its destination, passing through merging and diverging points along the way, according to its planned route.This is a schematic diagram showing an example where the planned route is displayed on the display screen of the device when the vehicle is driven along arrow A1 shown in Figure 3.This is a schematic diagram showing an example where the planned route is displayed on the display screen of the device when the vehicle is driven along arrow A1 shown in Figure 3.This is a schematic diagram showing the functional blocks of a processor in a vehicle-operatedThis is a schematic diagram showing how a vehicle's scheduled movements are displayed on the screen of another vehicle's display device.This diagram shows the vehicle's other planned movements and is a schematic diagram illustrating how a vehicle exits a highway when traveling on a two-lane highway.This flowchart shows the processes that the ECU processor performs at predetermined control cycles. Several embodiments of the present invention will be described below with reference to the drawings. However, these descriptions are intended merely as examples of preferred embodiments of the present invention and are not intended to limit the present invention to such specific embodiments. In the following description, similar components will be given the same reference numerals. Figure 1 is a schematic diagram showing the configuration of the action plan notification system installed in vehicle 100. This action plan notification system is applicable to a system that enables, for example, driving with the driver's hands off the steering wheel (hands-off driving). In this embodiment, such driving is assumed to be at least Level 2 or Level 3 as defined by the Society of Automotive Engineers (SAE). Hereafter, such driving will also be referred to as autonomous driving by the vehicle. In other words, in this embodiment, a vehicle capable of autonomous driving is a vehicle capable of driving at least at Level 2 or Level 3, and may be a vehicle capable of partial autonomous driving or a fully autonomous driving vehicle. The vehicle activity schedule notification system comprises an in-vehicle camera 105, a positioning information receiver 110, a vehicle control device 120, a wireless terminal 130, one or more sensors 140, a navigation device 150, an electronic control unit (ECU) 160, a display device 170, a speaker 180, an input device 190, and a storage device 195. These components are connected via an in-vehicle network compliant with standards such as the Controller Area Network (CAN). The in-vehicle camera 105 has a two-dimensional detector such as a CCD or C-MOS sensor and an imaging optical system. The in-vehicle camera 105 captures images of the area around the vehicle 100 (for example, the front, side, or rear of the vehicle) and generates an image representing the area around the vehicle 100. The positioning information receiver 110 acquires positioning information representing the current position and orientation of the vehicle 100. For example, the positioning information receiver 110 can be a GPS (Global Positioning System) receiver. The vehicle control equipment 120 comprises various devices related to vehicle control, including the engine 120a and motor 120b as drive sources for moving the vehicle, the friction brake 120c, and the steering device 120d, transmission (not shown), etc. The wireless terminal 130 communicates with other vehicles via vehicle-to-vehicle communication. For example, Dedicated Short-Range Communications (DSRC) is used for vehicle-to-vehicle communication. Communication with other surrounding vehicles may be conducted via an external server. One or more sensors 140 include sensors for monitoring the surroundings of the vehicle 100, such as lidar (light detection and ranging) and radar. The navigation device 150 determines the planned route from the vehicle 100's current location to its destination, following a predetermined route search method such as Dijkstra's algorithm. The ECU 160 comprises a processor 162, a memory 164, and a communication interface 166. The processor 162 has one or more CPUs and their peripheral circuits, and provides predetermined functions by executing computer programs
