These devices and devices are connected to each other by a multiple communication line such as a CAN (Controller Area Network) communication line, a serial communication line, a wireless communication network, or the like. The configuration illustrated in FIG. 1 is merely an example, and a part of the configuration may be omitted, or another configuration may be added.

  The camera 10 is a digital camera using a solid-state image sensor such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor). One or a plurality of cameras 10 are attached to any part of a vehicle (hereinafter referred to as the host vehicle M) on which the vehicle system 1 is mounted. When imaging the front, the camera 10 is attached to the upper part of the front windshield, the rear surface of the rearview mirror, or the like. For example, the camera 10 periodically and repeatedly images the periphery of the host vehicle M. The camera 10 may be a stereo camera.

  The radar device 12 radiates a radio wave such as a millimeter wave around the host vehicle M and detects a radio wave (reflected wave) reflected by the object to detect at least the position (distance and direction) of the object. One or a plurality of radar devices 12 are attached to arbitrary locations of the host vehicle M. The radar apparatus 12 may detect the position and speed of an object by FM-CW (Frequency Modulated Continuous Wave) method.

It communicates with various server devices via a wireless base station such as (registered trademark).

  The HMI 30 presents various information to the occupant of the host vehicle M and accepts an input operation by the occupant. The HMI 30 includes various display devices, speakers, buzzers, touch panels, switches, keys, and the like. An operation unit such as a touch panel, a switch, or a key in the HMI 30 functions as a reception unit that receives an operation of switching the operation mode of the host vehicle M from the manual operation mode to the automatic operation mode.

  The ETC vehicle-mounted device 40 includes a mounting unit on which an ETC card is mounted and a wireless communication unit that communicates with an ETC roadside device provided at a gate of a toll road. The wireless communication unit may be shared with the communication device 20. The ETC vehicle-mounted device 40 exchanges information such as an entrance toll gate and an exit toll gate by communicating with the ETC roadside device. The ETC roadside device determines a charge amount for the occupant of the host vehicle M based on these pieces of information, and proceeds with the billing process.

  The navigation device 50 calculates a route along which the host vehicle M travels and guides the route to the user. The detailed description of the navigation device 50 will be described later.

  For example, the MPU 60 functions as the recommended lane determination unit 61 and holds the first map information 62 in a storage device such as an HDD or a flash memory. The recommended lane determining unit 61 divides the route provided from the navigation device 50 into a plurality of blocks (for example, every 100 [m] with respect to the vehicle traveling direction), and refers to the first map information 62 for each block. Determine the recommended lane. The recommended lane determining unit 61 performs determination such as what number of lanes from the left to travel. The recommended lane determining unit 61 determines a recommended lane so that the host vehicle M can travel on a reasonable travel route for proceeding to the branch destination when there is a branch point or a merge point in the route. The MPU 60 determines whether or not automatic driving is possible along the determined recommended lane. Accordingly, the MPU 60 functions as a determination unit that determines whether the section included in the route searched by the navigation device 50 is either a section where automatic driving is possible or a section where automatic driving is impossible. .

  The first map information 62 is map information with higher accuracy than the navigation map DB 53 in the navigation device 50. The first map information 62 includes, for example, information on the center of the lane or information on the boundary of the lane. The first map information 62 may include road information, traffic regulation information, address information (address / postal code), facility information, telephone number information, and the like. Road information includes information indicating the type of road such as expressway, toll road, national road, prefectural road, road lane number, width of each lane, road gradient, road position (longitude, latitude, height). Information including 3D coordinates), curvature of lane curves, lane merging and branch point positions, signs provided on roads, and the like. The first map information 62 may be updated at any time by accessing another device using the communication device 20.

  The vehicle sensor 70 includes a vehicle speed sensor that detects the speed of the host vehicle M, an acceleration sensor that detects acceleration, a yaw rate sensor that detects an angular velocity around the vertical axis, a direction sensor that detects the direction of the host vehicle M, and the like.

  The driving operation element 80 includes, for example, an accelerator pedal, a brake pedal, a shift lever, a steering wheel, and other operation elements. A sensor that detects the amount of operation or the presence or absence of an operation is attached to the driving operator 80, and the detection result is the automatic driving control unit 100, or the traveling driving force output device 200, the brake device 210, and the steering device. 220 is output to one or both of 220.

  The automatic operation control unit 100 includes, for example, a first control unit 120 and a second control unit 140. The first control unit 120 and the second control unit 140 are realized by a processor (CPU) or the like executing a program (software). In addition, some or all of the functional units of the first control unit 120 and the second control unit 140 described below are LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), and FPGA (Field-Programmable Gate Array). ) Or the like, or may be realized by cooperation of software and hardware.

  The 1st control part 120 is provided with the outside world recognition part 121, the own vehicle position recognition part 122, and the action plan part 130, for example.

  The outside recognition unit 121 recognizes the positions of surrounding vehicles and the state of speed, acceleration, and the like based on information input from the camera 10, the radar device 12, and the finder 14 via the object recognition device 16. The position of the surrounding vehicle may be represented by a representative point such as the center of gravity or corner of the surrounding vehicle, or may be represented by an area expressed by the outline of the surrounding vehicle. The “state” of the surrounding vehicle may include acceleration and jerk of the surrounding vehicle, or “behavioral state” (for example, whether or not the lane is changed or is about to be changed). In addition to the surrounding vehicles, the external environment recognition unit 121 may recognize the positions of guardrails, utility poles, parked vehicles, pedestrians, and other objects.

  The own vehicle position recognition unit 122 recognizes, for example, the lane (traveling lane) in which the own vehicle M is traveling, and the relative position and posture of the own vehicle M with respect to the traveling lane. The own vehicle position recognition unit 122 is, for example, a road lane marking line pattern obtained from the first map information 62 (for example, an array of solid lines and broken lines) and a periphery of the own vehicle M recognized from an image captured by the camera 10. The traveling lane is recognized by comparing the road marking line pattern. In this recognition, the position of the host vehicle M acquired from the navigation device 50 and the processing result by INS (Inertial Navigation System) may be taken into consideration.

  The own vehicle position recognition unit 122 recognizes the position and posture of the own vehicle M with respect to the traveling lane, for example. FIG. 2 is a diagram illustrating a state in which the vehicle position recognition unit 122 recognizes the relative position and posture of the vehicle M with respect to the travel lane L1. The own vehicle position recognizing unit 122 makes, for example, a line connecting the deviation OS of the reference point (for example, the center of gravity) of the own vehicle M from the travel lane center CL and the travel lane center CL in the traveling direction of the own vehicle M. The angle θ is recognized as the relative position and posture of the host vehicle M with respect to the traveling lane L1. Instead, the host vehicle position recognition unit 122 recognizes the position of the reference point of the host vehicle M with respect to any side end of the host lane L1 as the relative position of the host vehicle M with respect to the traveling lane. Also good. The relative position of the host vehicle M recognized by the host vehicle position recognition unit 122 is provided to the recommended lane determination unit 61 and the action plan unit 130.

  The action planning unit 130 determines events that are sequentially executed in the automatic driving so that the recommended lane determining unit 61 determines the recommended lane and travels along the recommended lane, and can cope with the surrounding situation of the host vehicle M. Events include, for example, a constant speed event that travels in the same lane at a constant speed, a follow-up event that follows the preceding vehicle, a lane change event, a merge event, a branch event, an emergency stop event, and automatic driving There are handover events to switch to manual operation. Further, during execution of these events, actions for avoidance may be planned based on the surrounding situation of the host vehicle M (the presence of surrounding vehicles and pedestrians, lane narrowing due to road construction, etc.).

  The action planning unit 130 generates a target track on which the host vehicle M will travel in the future. The target trajectory includes, for example, a velocity element. For example, the target trajectory is generated as a set of target points (orbit points) that should be set at a plurality of future reference times for each predetermined sampling time (for example, about 0 comma [sec]) and reach these reference times. The For this reason, when the width | variety of a track point is wide, it has shown running in the area between the track points at high speed.

  FIG. 3 is a diagram illustrating a state in which a target track is generated based on the recommended lane. As shown in the figure, the recommended lane is set so as to be convenient for traveling along the route to the destination. The behavior planning unit 130 activates a lane change event, a branch event, a merge event, or the like when it reaches a predetermined distance before the recommended lane switching point (may be determined according to the type of event). If it becomes necessary to avoid an obstacle during the execution of each event, an avoidance trajectory is generated as shown in the figure.

  For example, the behavior planning unit 130 generates a plurality of target trajectory candidates, and selects an optimal target trajectory at that time based on the viewpoints of safety and efficiency.

  FIG. 4 is another diagram showing how a target track is generated based on the recommended lane. It is assumed that the toll gate of the toll road is included on the route generated by the navigation device 50. When the toll gate of the toll road is included in the route, the action plan unit 130 determines the position on the departure side by a predetermined distance from the position of the toll gate on the route as a position to stop the automatic driving. In addition, the action planning unit 130 determines the position on the destination side by a predetermined distance from the position of the toll gate on the route as the position at which the automatic driving is started.

  The behavior planning unit 130 determines the position where the automatic driving is stopped when the toll gate is included in the route, but is not limited thereto. The action planning unit 130 may determine the position where the automatic driving is stopped based on the position of the interchange closest to the destination among the interchanges on the route.

  The second control unit 140 includes a travel control unit 141. The traveling control unit 141 controls the traveling driving force output device 200, the brake device 210, and the steering device 220 so that the host vehicle M passes the target track generated by the behavior planning unit 130 at a scheduled time. To do.

  The traveling driving force output device 200 outputs a traveling driving force (torque) for traveling of the vehicle to driving wheels. The travel driving force output device 200 includes, for example, a combination of an internal combustion engine, an electric motor, a transmission, and the like, and an ECU that controls these. The ECU controls the above-described configuration in accordance with information input from the travel control unit 141 or information input from the driving operator 80.

  The brake device 210 includes, for example, a brake caliper, a cylinder that transmits hydraulic pressure to the brake caliper, an electric motor that generates hydraulic pressure in the cylinder, and a brake ECU. The brake ECU controls the electric motor according to the information input from the traveling control unit 141 so that the brake torque corresponding to the braking operation is output to each wheel. The brake device 210 may include, as a backup, a mechanism that transmits the hydraulic pressure generated by operating the brake pedal included in the driving operation element 80 to the cylinder via the master cylinder. The brake device 210 is not limited to the configuration described above, and may be an electronically controlled hydraulic brake device that controls the actuator according to information input from the travel control unit 141 and transmits the hydraulic pressure of the master cylinder to the cylinder. Good.

  The steering device 220 includes, for example, a steering ECU and an electric motor. For example, the electric motor changes the direction of the steered wheels by applying a force to a rack and pinion mechanism. The steering ECU drives the electric motor according to the information input from the travel control unit 141 or the information input from the driving operator 80, and changes the direction of the steered wheels.

  The navigation map DB 53 is stored in a storage device such as an HDD (Hard Disk Drive) or a flash memory. The navigation map DB 53 is a database in which event point information is included in map information. The map information is, for example, information in which a road shape is expressed by a link indicating a road and nodes connected by the link. Further, the map information may include detailed information on the road such as the curvature of the road. The event point is a point where name information for specifying the name of the facility or the point is added to the position information of the point in the navigation map DB 53.

The navigation control unit 52 supplies the determined route information to the MPU 60.

  The calculation unit 522 calculates the distance between the current position of the host vehicle M and the event point. In addition, the calculation unit 522 estimates the time at which the host vehicle M reaches the event point based on the distance between the current position of the host vehicle M and the event point. Furthermore, the calculating part 522 acquires automatic driving | operation area information. The automatic driving section information is information representing a result of determining whether a section included in the route is a section in which automatic driving is possible or a section in which automatic driving is not possible. For example, the calculation unit 522 automatically determines whether the section included in the route determined by the MPU 60 is either a section where automatic driving is possible or a section where automatic driving is impossible. Get driving section information.

  The guidance control unit 523 performs route guidance using the display unit 55 and the speaker unit 56 based on the route determined by the route search unit 521.
