Summary of the Invention

Problems to be Solved by the Invention

[0004] In such a hybrid vehicle, a motor driving area in which it should travel by motor driving with the engine stopped and traveling only by the power from the motor is predetermined in the map information, and when traveling in the motor driving area, area travel support control may be executed to control so as to switch the travel mode to the motor driving mode and drive by the motor. Further, in such a hybrid vehicle, there may be provided a travel mode switching switch that can be operated by the driver. When the driver operates the travel mode switching switch while the area travel support control is being executed, it is necessary to adjust whether to prioritize the area travel support control or the operation of the travel mode switching switch by the driver.

[0005] The main object of the hybrid vehicle of the present disclosure is to achieve adjustment between area travel support control and the operation of the travel mode switching switch.

Means for Solving the Problem

[0006] The hybrid vehicle of the present disclosure has adopted the following means to achieve the above main object.

[0007] The hybrid vehicle of the present disclosure includes an engine capable of outputting driving power, a motor capable of outputting driving power, a power storage device capable of exchanging power with the motor, a control device that controls the engine and the motor by switching between a motor driving mode in which the vehicle travels by the power from the motor with the engine stopped and a normal driving mode in which the vehicle travels by the power from the engine and the power from the motor as needed, and executes area travel support control for switching to the motor driving mode and performing motor driving when traveling in a motor driving area preset as an area where the vehicle should travel by motor driving; and is a hybrid vehicle comprising wherein when the travel mode change switch is operated during travel in the motor travel area by the area travel support control, the control device stops the area travel support control and controls the vehicle to travel in the normal travel mode. This is the feature.

[0008] In the hybrid vehicle of the present disclosure, there are provided an engine capable of outputting driving power, a motor capable of outputting driving power, a power storage device capable of exchanging power with the motor, a motor driving mode for performing motor driving in which the vehicle travels by power from the motor with the engine stopped, and a control device for controlling the engine and the motor by switching between the motor driving mode and a normal driving mode for performing normal driving by power from the engine and power from the motor as necessary. When traveling in a motor driving area preset as an area where the vehicle should travel in the motor driving mode, the control device executes area travel support control for performing motor driving by switching to the motor driving mode. When the travel mode changeover switch is operated while the vehicle is traveling in the motor driving area by the area travel support control, the control device stops the area travel support control and controls the vehicle to travel in the normal driving mode. That is, the operation of the travel mode changeover switch, which represents the driver's intention, is given priority over the area travel support control. Thereby, it is possible to coordinate the area travel support control and the operation of the travel mode changeover switch.

[0009] In the hybrid vehicle of the present disclosure, when the control device stops the area travel support control and controls the vehicle to travel in the normal driving mode due to the operation of the travel mode changeover switch during the execution of the area travel support control, the control device may continue to stop the area travel support control until the system is stopped. That is, during that trip, the stop of the area travel support control is continued, and in the next trip (after the system is started), the area travel support control is newly executed. Thereby, it is possible to coordinate the subsequent area travel support control and the operation of the travel mode changeover switch.

[0010] In the hybrid vehicle of the present disclosure, which has an indicator for indicating that the vehicle is traveling in the motor drive mode, when the driving mode changeover switch is operated while the vehicle is traveling in the motor drive area under the area drive support control and the indicator indicates that the vehicle is traveling in the motor drive mode, the control device may stop the area drive support control and control the vehicle to travel in the normal drive mode. When the vehicle is traveling in the motor drive area under the area drive support control and the indicator indicates that the vehicle is traveling in the motor drive mode, the driver can recognize that the vehicle is traveling in the motor drive mode. Therefore, when the driving mode changeover switch is operated at this time, by stopping the area drive support control and controlling the vehicle to travel in the normal drive mode, the intention of the driver to switch from the motor drive mode to the normal drive mode can be prioritized, and the adjustment between the area drive support control and the operation of the driving mode changeover switch can be achieved.

[0011] In the hybrid vehicle of the present disclosure, which has an indicator for indicating that the vehicle is traveling in the motor drive mode, when the driving mode changeover switch is operated while the vehicle is traveling in the motor drive area under the area drive support control and the indicator does not indicate that the vehicle is traveling in the motor drive mode, the control device may continue the motor drive under the area drive support control and cause the indicator to indicate that the vehicle is traveling in the motor drive mode. When the driving mode changeover switch is operated while the vehicle is traveling in the motor drive area under the area drive support control and the indicator does not indicate that the vehicle is traveling in the motor drive mode, since the driver can be judged to have operated the driving mode changeover switch to drive the vehicle because the driver is not driving the vehicle in the motor drive mode, the motor drive under the area drive support control is continued, and the indicator indicates that the vehicle is traveling in the motor drive mode to inform the driver that the vehicle is driving in the motor drive mode. Thereby, the intention of the driver to drive the vehicle in the motor drive mode can be prioritized, and the adjustment between the area drive support control and the operation of the driving mode changeover switch can be achieved.

Embodiments for Carrying Out the Invention

[0013] Next, embodiments for carrying out the present disclosure will be described. FIG. 1 is a block diagram showing, as an example of a hybrid vehicle 20 according to an embodiment of the present disclosure, blocks centered around a hybrid electronic control unit (hereinafter referred to as a hybrid ECU) 50. The hybrid vehicle 20 of the embodiment includes an engine EG and a motor MG as power sources, as shown in the figure. The hybrid vehicle 20 of the embodiment has, as driving modes, a motor driving mode in which it travels by the power from the motor MG with the operation of the engine EG stopped, and a normal driving mode in which the engine EG is operated as necessary and it travels by the power from the engine EG and the power from the motor MG.

[0014] In addition to the power source, the hybrid vehicle 20 of the embodiment includes an ignition switch 21, a GPS (Global Positioning System, Global Positioning Satellite) 22, an in-vehicle camera 24, a millimeter-wave radar 26, an acceleration sensor 28, a vehicle speed sensor 30, an accelerator sensor 32, a brake sensor 34, a mode switching switch 36, a battery actuator 38, a battery 40, an electronic control unit for air conditioner (hereinafter referred to as air conditioner ECU) 42, an air conditioner compressor 44, a hybrid ECU 50, an accelerator actuator 60, a brake actuator 62, a brake device 64, a display device 66, a motor driving indicator 67, a meter 68, a DCM (Data Communication Module) 70, a navigation system 80, and the like.

[0015] The GPS 22 is a device that detects the position of the vehicle based on signals transmitted from a plurality of GPS satellites. The in-vehicle camera 24 is a camera that images the surroundings of the vehicle. For example, a front camera that images the front of the vehicle and a rear camera that images the rear of the vehicle are applicable. The millimeter-wave radar 26 detects the inter-vehicle distance and relative speed between the host vehicle and the vehicle in front, or detects the inter-vehicle distance and relative speed between the host vehicle and the vehicle behind.

[0016] The acceleration sensor 28 is a sensor that detects, for example, the acceleration of the vehicle in the front-rear direction or the acceleration of the vehicle in the left-right direction (lateral direction). The vehicle speed sensor 30 detects the vehicle speed of the vehicle based on the wheel speed and the like. The accelerator sensor 32 detects the accelerator opening or the like corresponding to the depression amount of the driver's accelerator pedal. The brake sensor 34 detects the brake position or the like as the depression amount of the driver's brake pedal. The mode switching switch 36 is disposed near the steering wheel of the driver's seat and is a switch for switching between the motor driving mode and the normal driving mode. Basically, when the mode switching switch 36 is operated in the motor driving mode, it switches to the normal driving mode, and when the mode switching switch 36 is operated in the normal driving mode, it switches to the motor driving mode.

[0017] The battery actuator 38 detects the state of the battery 40, such as the voltage between terminals, charge / discharge current, and battery temperature, and manages the battery 40 based on these. The battery actuator 38 may calculate the state of charge SOC as the ratio of the remaining charge capacity to the total charge capacity based on the charge / discharge current, or calculate the maximum allowable output power (output limit Wout) that may be output from the battery 40 or the maximum allowable input power (input limit Win) that may be input to the battery 40 based on the state of charge SOC, battery temperature, etc. The battery 40 is configured as a rechargeable secondary battery, and for example, a lithium-ion battery, nickel-metal hydride battery, lead-acid battery, etc. can be used.

[0018] The air conditioner ECU 42 is configured as a microcomputer centered around a CPU (not shown), and in addition to the CPU, it includes a ROM, RAM, flash memory, input port, output port, communication port, etc. The air conditioner ECU 42 is incorporated in an air conditioning device that air-conditions the passenger compartment, and drives and controls the air conditioner compressor 44 in the air conditioning device so that the temperature of the passenger compartment becomes the set temperature.

[0019] The engine EG is configured as, for example, an internal combustion engine. The motor MG is configured as an electric motor that also functions as a generator such as a synchronous motor generator. The motor MG is connected to the battery 40 via an inverter (not shown), and can output driving force using the power supplied from the battery 40 or charge the battery 40 with the generated power.

[0020] The hybrid ECU 50 is configured as a microcomputer centered around a CPU (not shown), and in addition to the CPU, it is equipped with a ROM, a RAM, a flash memory, an input port, an output port, a communication port, etc. The hybrid ECU 50 sets the driving mode, and based on the set driving mode, the accelerator opening from the accelerator sensor 32, the brake position from the brake sensor 34, the output limit and input limit from the battery actuator 38, it sets the target operating point (target rotational speed and target torque) of the engine EG and the torque command of the motor MG. Note that the hybrid ECU 50 does not start when the accessory is on and starts when the radio is on.

[0021] When the motor is running, the hybrid ECU 50 sets the required driving force and required power based on the accelerator opening from the accelerator sensor 32 and the vehicle speed from the vehicle speed sensor 30, sets the torque command of the motor MG so as to output the required driving force and required power to the vehicle, and transmits the set torque command to the accelerator actuator 60. When the vehicle is running in hybrid mode, the hybrid ECU 50 sets the target operating point of the engine EG and the torque command of the motor MG so as to output the required driving force and required power to the vehicle, and transmits the target operating point and the torque command to the accelerator actuator 60. Also, when the brake pedal is depressed, the hybrid ECU 50 sets the required braking force based on the brake position from the brake sensor 34 and the vehicle speed from the vehicle speed sensor 30, sets the torque command for regeneration to control the motor MG in regeneration based on the required braking force and the vehicle speed, sets the target braking force by the braking device, transmits the torque command to the accelerator actuator 60, and transmits the target braking force to the brake actuator 62.

[0022] The accelerator actuator 60 drives and controls the engine EG and the motor MG according to the target operation point and torque command set by the hybrid ECU 50. The accelerator actuator 60 performs intake air amount control, fuel injection control, ignition control, intake valve opening / closing timing control, etc. so that the engine EG operates at the target operation point (target rotational speed and target torque). Further, the accelerator actuator 60 performs switching control of the switching elements of the inverter included in order to drive the motor MG so that torque corresponding to the torque command is output from the motor MG.

[0023] The brake actuator 62 controls the brake device 64 so that the target braking force set by the hybrid ECU 50 acts on the vehicle by the brake device 64. The brake device 64 is configured as, for example, a hydraulically driven friction brake.

[0024] The display device 66 is incorporated in, for example, the installation panel in front of the driver's seat, displays various information, and also functions as a touch panel. The motor running indicator 67, although not shown, is incorporated in the installation panel in front of the driver's seat, lights up when the motor is running, and goes out when the motor is not running.

[0025] The DCM (Data Communication Module) 70 transmits information of the host vehicle to the traffic information management center 100 and receives road traffic information from the traffic information management center 100. Examples of the information of the host vehicle include the position of the host vehicle, vehicle speed, driving power, driving mode, etc. Examples of the road traffic information include information on current and future traffic jams, information on the current average vehicle speed and predicted values of future average vehicle speeds in sections on the driving route, information on traffic regulations, information on weather, information on road surface conditions, information on maps, etc. The DCM 70 communicates with the traffic information management center 100 at predetermined intervals (for example, every 30 seconds, every 1 minute, every 2 minutes, etc.).

[0026] The navigation system 80 is a system that guides the host vehicle to a set destination, and includes a display unit 82 and a map information database 84. The display unit 82 is a functional block having a function of displaying on the display device 66 a route to the destination, the position of the host vehicle, etc. based on map information. The navigation system 80 communicates with the traffic information management center 100 via the DCM (Data Communication Module) 70. When a destination and waypoints are set, the navigation system 80 sets a route based on the information of the destination and waypoints, the information of the current location (the position of the current host vehicle) acquired by the GPS 22, and the information stored in the map information database 84. Then, the navigation system 80 communicates with the traffic information management center 100 every predetermined time (for example, every 3 minutes or every 5 minutes) to acquire road traffic information, and performs route guidance based on the road traffic information. The map information stored in the map information database 84 includes not only data as a map, but also road gradients, road types, elevations, etc. for each driving section.

[0027] When the navigation system 80 provides route guidance, every time (or at predetermined intervals) it acquires road traffic information from the traffic information management center 100, it generates, as preview information, load information necessary to travel each driving section in the driving route, such as information on each driving section within the driving route and information on driving load among the road traffic information acquired from the traffic information management center 100, based on information such as the vehicle speed of the host vehicle, the driving power of the host vehicle, and the driving mode of the host vehicle, and transmits it to the hybrid ECU 50. Note that the preview information also includes information on the host vehicle such as the position, vehicle speed, driving power, and driving mode of the host vehicle, information on current and future traffic jams, information on the current average vehicle speed and predicted values of future average vehicle speeds in sections on the driving route, information on traffic regulations, information on weather, information on road surface conditions, and information on maps. The information on maps also includes areas where motor vehicle travel is to be permitted (motor vehicle travel areas) defined by municipalities and the like. The navigation system 80 can also set a motor vehicle travel area by designating an area such as an area near the user's home by user operation. The navigation system 80 transmits a signal indicating whether or not it is a motor vehicle travel area to the hybrid ECU 50 when the host vehicle is traveling.

[0028] Next, the operation of the hybrid vehicle 20 configured in this way, particularly the operation when traveling in the motor vehicle travel area, will be described. FIG. 2 is a flowchart showing an example of area travel support control executed by the hybrid ECU 50. This control is executed from when the ignition switch 21 is turned on and the system is started until the end process is performed.

[0029] When the area driving support control is executed, the hybrid ECU 50 first acquires information on the planned or estimated driving route within a predetermined range from the current location (step S100). As the predetermined range, 5 km, 10 km, 15 km, etc. can be used. The planned driving route is the driving route planned by the navigation system 80 as route guidance from the current location to the destination when the destination is set, and the estimated driving route is the driving route where driving is estimated from the current location. As the information to be acquired, in addition to the above-described preview information, the presence or absence of a motor driving area, and when there is a motor driving area, the start point and end point of the motor driving area, etc. are included.

[0030] Next, it is determined whether there is a motor driving area in the planned or estimated driving route within the predetermined range (step S110). When it is determined that there is no motor driving area, it is determined whether the ignition switch 21 has been turned off (step S200), and when it is determined that the ignition switch 21 has not been turned off (is in the on state), the process returns to the process of acquiring information on the planned or estimated driving route within the predetermined range from the current location in step S100.

[0031] When it is determined in step S110 that there is a motor driving area in the planned or estimated driving route within the predetermined range, preparation for driving in the motor driving area is performed (step S120). The preparation for driving in the motor driving area includes preparing to increase the state of charge SOC of the battery 40 from a point a predetermined distance (such as 1 km or 2 km) before the start point of the motor driving area so that driving in the motor driving area becomes possible.

[0032] Subsequently, wait until reaching the starting point of the motor driving area (step S130), switch to the motor driving mode and drive by motor driving (step S140). Then, it is determined whether there has been an operation of the mode change switch 36 (step S150). When it is determined that there has been no operation of the mode change switch 36, it is determined whether the end point of the motor driving area has been reached (step S180). When it is determined that the end point of the motor driving area has not yet been reached, the process returns to the process of determining whether there has been an operation of the mode change switch 36 in step S150. When there is no operation of the mode change switch 36 during the driving in the motor driving area, the motor driving in the motor driving mode continues until the end point of the motor driving area is reached. When it is determined in step S180 that the end point of the motor driving area has been reached, the driving mode is switched to the normal driving mode (step S190), and it is determined whether the ignition switch 21 has been turned off (step S200). When it is determined that the ignition switch 21 has not been turned off (is in the on state), the process returns to the process of acquiring information on the planned or estimated driving route within a predetermined range from the current location in step S100. On the other hand, when it is determined that the ignition switch 21 has been turned off, the area driving support control is terminated.

[0033] When the mode change switch 36 is operated during motor driving in the motor driving area, an affirmative determination is made in step S150, and it is determined whether or not the motor driving indicator 67 is lit (step S160). In the hybrid vehicle of the embodiment, when the user wants to recognize the driving mode when automatically switching from the normal driving mode to the motor driving mode by the area driving support control, the motor driving indicator 67 is set to be lit when driving the motor during the execution of the area driving support control. When the user does not want to recognize the driving mode when automatically switching from the normal driving mode to the motor driving mode by the area driving support control, the motor driving indicator 67 can be set to be lit when driving the motor during the execution of the area driving support control. In the former case, the motor driving indicator 67 is lit when driving the motor in the motor driving mode by the area driving support control. In the latter case, the motor driving indicator 67 is not lit even when driving the motor in the motor driving mode by the area driving support control.

[0034] When it is determined in step S160 that the motor driving indicator 67 is not lit, the motor driving indicator 67 is lit (step S170), and it is determined whether or not the end point of the motor driving area has been reached while continuing the motor driving (step S180). When it is determined that the end point of the motor driving area has not been reached yet, the process returns to the process of determining whether or not there has been an operation of the mode change switch 36 in step S150.

[0035] When it is determined in step S160 that the motor running indicator 67 is lit, the mode is switched from the motor running mode to the normal running mode (step S210), it is notified that the area driving support control is terminated (step S220), and this process is terminated. In this way, the operation of the mode change switch 36 while the motor running indicator 67 is lit during the area driving support control is determined to be the driver's intention to switch from the motor running mode to the normal running mode. Even in the motor running area, running in the normal running mode is executed, and at the same time, the area driving support control is terminated. Thereby, a running mode that gives priority to the driver's intention can be set. Note that the determination in step S160 that the motor running indicator 67 is lit is made when the motor running indicator 67 is lit when the vehicle is running in the motor running area during the execution of the area driving support control and the operation of the mode change switch 36 is performed for the first time in the motor running area, or when the motor running indicator 67 is not lit when the vehicle is running in the motor running area during the execution of the area driving support control and the second operation of the mode change switch 36 is performed in the motor running area.

[0036] FIG. 3 and FIG. 4 show an example of the state changes of the area driving support control, the driving area, the driving mode, the motor driving indicator 67, and the mode change switch 36 when the motor driving indicator 67 is lit during motor driving by the area driving support control (FIG. 3) and when it is not lit (FIG. 4). In the figure, point P1 is the start point of the motor driving area, and point P4 is the end point of the motor driving area. Points P2 and P3 are the points where the driver operates the mode change switch 36 during the motor driving area, and point P5 is the point where the driver operates the mode change switch 36 after the motor driving area ends. In the case where the motor driving indicator 67 is lit during motor driving by the area driving support control, as shown in FIG. 3, at point P2 where the mode change switch 36 is first operated after entering the motor driving area, the motor driving mode is switched to the normal driving mode, and the area driving support control ends. After that, each time the driver operates the mode change switch 36 (points P3, point P5), it is switched from the normal driving mode to the motor driving mode or from the motor driving mode to the normal driving mode. On the other hand, in the case where the motor driving indicator 67 is not lit during motor driving by the area driving support control, as shown in FIG. 4, at point P2 where the mode change switch 36 is first operated after entering the motor driving area, since the motor driving indicator 67 is not lit, the motor driving indicator 67 is lit and the motor driving mode is continued. At point P3 where the driver's second operation of the mode change switch 36 is performed, since the motor driving indicator 67 is lit, the motor driving mode is switched to the normal driving mode, and the area driving support control ends. After that, each time the driver operates the mode change switch 36 (point P5), it is switched from the normal driving mode to the motor driving mode or from the motor driving mode to the normal driving mode.

[0037] In the hybrid vehicle 20 of the embodiment described above, when the driver operates the mode change switch 36 during motor driving in the motor driving area by area driving support control, the area driving support control is terminated and the vehicle travels in the normal driving mode. Thereby, the operation of the mode change switch 36, which is the driver's intention, can be prioritized over the area driving support control. As a result, it is possible to coordinate the area driving support control and the operation of the mode change switch 36 by the driver.

[0038] In the hybrid vehicle 20 of the embodiment, when the driver operates the mode change switch 36 during motor driving in the motor driving area by area driving support control while the motor driving indicator 67 is lit, the area driving support control is terminated and the vehicle travels in the normal driving mode. On the other hand, when the driver operates the mode change switch 36 during motor driving in the motor driving area by area driving support control without the motor driving indicator 67 being lit (in the off state), the motor driving indicator 67 is lit and the motor driving by the area driving support control is continued. Thereby, even though the motor driving by the area driving support control is being performed, since the motor driving indicator 67 is off, it is possible to also handle the case where the driver operates the mode change switch 36 to switch to the motor driving mode thinking that the vehicle is traveling in the normal driving mode.

[0039] In the hybrid vehicle 20 of the embodiment, although it is assumed that the user can set whether to turn on or off the motor driving indicator 67 during motor driving by area driving support control, it may be assumed that such user settings cannot be made.

[0040] In the hybrid vehicle 20 of the embodiment, when the area driving support control is terminated due to the driver operating the mode change switch 36 during motor driving in the motor driving area by area driving support control, it is assumed that the termination of the area driving support control is notified, but it may not be notified.
