Abstract

A vehicle control mode switching device (100) that switches between a non-control mode in which the control amount is not automatically changed, an auto mode in which the control amount is automatically changed, and a manual mode in which the control amount is manually changed. The control mode switching device includes a first operating device (24) and a second operating device (18) operated by a driver, and a control unit (10) configured to switch the control mode based on the operation of the first and second operating devices. The control unit switches the control mode between two of three modes based on the operation of the first operating device to set it as a base mode (80, 82), and switches the control mode between the remaining mode other than the two modes among three modes and the base mode based on the operation of the second operating device.

Description

Vehicle Control Mode Switching Device The present invention relates to a control mode switching device for a vehicle, such as an automobile. In vehicles such as automobiles, a control mode switching device is known to switch the control mode of the vehicle when operated by an operator. For example, Patent Document 1 below describes a control mode switching device that switches the driving mode of the vehicle between an electric mode and a hybrid mode and switches the gear stage of an automatic transmission by operating a paddle shift lever. FIG. 1 is a schematic diagram showing an operation support device equipped with a control mode switching device according to an embodiment. FIG. 2 is a drawing showing the interior of a vehicle equipped with a control mode switching device according to a first embodiment. Figure 3 is a diagram showing the relationship between the switching operation of the control mode and the change of the control mode, with the non-control mode and auto mode as the base mode and the manual mode as the remaining mode. FIG. 4 is a flowchart corresponding to the control mode switching control program in the first embodiment. FIG. 5 is a drawing showing the interior of a vehicle equipped with a control mode switching device according to a second embodiment. Figure 6 is a diagram showing the relationship between the switching operation of the control mode and the change of the control mode, with the non-control mode and manual mode as the base mode and the auto mode as the remaining mode. Figure 7 shows a map of multiple driving torques representing the relationship between the accelerator opening degree A, vehicle speed V, and driving torque Td. FIG. 8 is a flowchart corresponding to a control mode switching control program in a second embodiment. A vehicle control mode switching device according to an embodiment of the present invention will be described in detail below with reference to the attached drawings. As illustrated in FIG. 1, a control mode switching device (100) according to an embodiment of the present invention is applied to a driving support device (104) of a vehicle (102) and includes a driving support ECU (10). The vehicle (102) is a vehicle capable of automatic driving and is equipped with a meter ECU (20), a driving ECU (30), and a braking ECU (40). An ECU refers to an Electronic Control Unit having a microcomputer as its main component. The microcomputer of each ECU includes a CPU, ROM, RAM, readable non-volatile memory (N/M), and an interface (I/F). The CPU realizes various functions by executing instructions (programs, routines) stored in the ROM. In addition, these ECUs are connected to each other so that data can be exchanged (communicated) via a CAN (Controller Area Network) (106). Therefore, detection values of sensors (including switches) connected to a specific ECU are transmitted to other ECUs. The driving support ECU (10) is a central control device that performs driving support controls such as deceleration support control, following distance control, and lane keeping control. In an embodiment, the driving support ECU (10) cooperates with other ECUs to perform driving support controls that support the driver's driving when the vehicle (102) is driving, and also performs control to switch the control mode of the driving support controls. A camera sensor (12), a radar sensor (14), a setting actuator (16), and an operating device (18) are connected to the driving support ECU (10). The camera sensor (12) and the radar sensor (14) each include a plurality of camera devices and a plurality of radar devices, and function as a target information acquisition device (15) for acquiring target information around the vehicle (102). Each camera unit of the camera sensor (12) is equipped with a camera unit that photographs the surroundings of the vehicle (102), although not shown in the drawing, and a recognition unit that interprets image data obtained by photographing by the camera unit to recognize objects such as white lines on the road and other vehicles. The recognition unit supplies information regarding the recognized objects to the driving support ECU (10) at predetermined intervals. Each radar unit of the radar sensor (14) uses millimeter wave radio waves to detect the distance between the vehicle and the object, the relative speed between the vehicle and the object, and the relative position (direction) of the object relative to the vehicle, and supplies information indicating these to the driving support ECU (10) at predetermined intervals. In addition, LiDAR (Light Detection And Ranging) may be used instead of the radar sensor (14) or in addition to the radar sensor (14). The setting actuator (16) is provided in a position operable by the driver and is operated by the driver. Although not shown in FIG. 1, the setting actuator (16) includes a deceleration support switch. The driving support ECU (10) performs deceleration support control when the deceleration sup
