Summary of the Invention

Problems to be Solved by the Invention

[0004] In recent years, in order to suppress noise around the home, a user may set the home as a motor traveling point, and set a predetermined distance range of the set motor traveling point as a motor traveling area. At this time, the motor traveling point and the motor traveling area are set on a road on a map. For this reason, if the system stops after traveling on a passageway, etc. within a private land that is not recognized as a road on the map after reaching the motor traveling point, it becomes difficult to specify the current location on the map when the system is started later, and there may be a case where the engine is started immediately after the system is started.

[0005] The main object of the hybrid vehicle of the present disclosure is to enable traveling by motor even when the system is started after the system stops after traveling on a passageway, etc. within a private land after reaching the motor traveling point.

Means for Solving the Problems

[0006] In order to achieve the above main object, the hybrid vehicle of the present disclosure adopts the following means.

[0007] The hybrid vehicle of the present disclosure 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 map information storage device for storing map information, When 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 to control the engine and the motor, a control device is provided to control the vehicle to travel in the motor driving mode within a predetermined distance range from a motor driving point set on the map information; A hybrid vehicle comprising: The control device When reaching within a predetermined distance range from the motor driving point and starting to travel in the motor driving mode, sets the motor driving history to on, When the motor driving history is on when the system is started, controls the vehicle to travel in the motor driving mode. It is characterized by the above.

[0008] 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 motor driving mode in which the vehicle travels by power from the motor with the engine stopped, and a normal driving mode in which the vehicle travels by power from the engine and power from the motor as needed, and a control device that controls the engine and the motor by switching between them. The control device controls the vehicle to travel in the motor driving mode within a predetermined distance range from a motor driving point set on the map information. At this time, when starting to travel in the motor driving mode within the predetermined distance range from the motor driving point, the motor driving history is set to on. Further, when the motor driving history is on when the system is started, the control device controls the vehicle to travel in the motor driving mode. Thereby, even when the vehicle travels on a passage within a private area after reaching the motor driving point and then the system stops and then the system is started, it is possible to travel by motor driving.

[0009] In the hybrid vehicle of the present disclosure, the control device may be configured to store the travel distance for a predetermined period after reaching the motor driving point, and when the motor driving history is on when the system is started, control the vehicle to travel at least the travel distance from the system start point in the motor driving mode. By doing so, even if the travel distance after reaching the motor driving point becomes long, it is possible to travel in the motor driving mode until at least the travel distance is traveled after the subsequent system start. Here, the predetermined period includes the period from the start of the motor driving mode after reaching the motor driving point until the system is turned off, and the period from the start of off-road (such as a road other than a public road) travel after reaching the motor driving point until the system is turned off.

[0010] In the hybrid vehicle of the present disclosure, when a predetermined cancellation condition is satisfied while the motor driving history is on, even if the vehicle has not traveled a distance greater than or equal to the travel distance in the motor driving mode, the motor driving history may be turned off and the motor driving mode may be terminated. In this case, the predetermined cancellation condition may include at least one of a condition determined to have passed the motor driving point and a condition in which the driver has instructed a request to terminate the motor driving mode. The condition in which the driver has instructed a request to terminate the motor driving mode includes, for example, a case where the driver has operated to cancel the motor driving mode using a switch operation or a remote operation.

[0011] In the hybrid vehicle of the present disclosure, when the motor driving mode is being implemented with the motor driving history on, if at least one of the following conditions is satisfied: the vehicle speed becomes equal to or higher than a predetermined vehicle speed, or the state of charge of the power storage device becomes less than a predetermined ratio, the motor driving mode is stopped while keeping the motor driving history on, and then, if the vehicle speed becomes less than the predetermined vehicle speed or the state of charge of the power storage device becomes equal to or higher than the predetermined ratio with the motor driving history on, the motor driving mode may be restarted. That is, when the motor driving history is on, if the vehicle speed becomes equal to or higher than a predetermined vehicle speed or the state of charge of the power storage device becomes less than a predetermined ratio, the motor driving mode is temporarily stopped, and then, if the vehicle speed becomes less than the predetermined vehicle speed or the state of charge of the power storage device becomes equal to or higher than the predetermined ratio, the motor driving mode is restarted. Thereby, even if the motor driving mode is temporarily stopped due to the establishment of a condition where the motor driving mode cannot be maintained when the motor driving history is on, the motor driving mode can be restored when the motor driving mode returns to a possible state.

Mode for Carrying Out the Invention

[0013] Next, the mode (embodiment) for carrying out the present disclosure will be described. FIG. 1 is a block diagram showing an example of a hybrid vehicle 20 as an embodiment of the present disclosure as a block centered on a hybrid electronic control unit (hereinafter referred to as hybrid ECU) 50. As shown in the figure, the hybrid vehicle 20 of the embodiment includes an engine EG and a motor MG as power sources. The hybrid vehicle 20 of the embodiment has, as driving modes, a motor driving mode in which the vehicle 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 the vehicle travels by the power from the engine EG and the power from the motor MG. The normal driving mode includes a CD mode (Charge Depleting mode) that prioritizes electric driving so as to decrease the state of charge SOC of the battery 40, and a CS mode (Charge Sustaining mode) that combines electric driving and hybrid driving so as to maintain the state of charge SOC of the battery 40 at a target ratio.

[0014] The hybrid vehicle 20 of the embodiment includes, in addition to the power source, 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 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 driving state 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, and for example, a front camera that images the front of the vehicle or a rear camera that images the rear of the vehicle is 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 or the like. The accelerator sensor 32 detects the accelerator opening or the like according to the depression amount of the accelerator pedal by the driver. The brake sensor 34 detects the brake position or the like as the depression amount of the brake pedal by the driver. The mode switch 36 is disposed near the steering wheel in the driver's seat and is a switch for switching between the motor driving mode and the normal driving mode.

[0017] The battery actuator 38 detects the state of the battery 40, such as the voltage between terminals, the charge and discharge current, and the 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 and 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, the battery temperature, etc. The battery 40 is configured as a rechargeable secondary battery, and for example, a lithium-ion battery, a nickel-metal hydride battery, a lead-acid battery, etc. can be used.

[0018] The air conditioner ECU 42 is configured as a microcomputer centered on a CPU (not shown), and includes a ROM, a RAM, a flash memory, an input port, an output port, a communication port, etc. in addition to the CPU. 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 an internal combustion engine, for example. 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 a 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 sets the target operating point (target rotational speed and target torque) of the engine EG and the torque command of the motor MG 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. 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 for 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 driving state indicator 67 has an EV indicator and an HV indicator (not shown). When the vehicle is running on the motor, the EV indicator lights up and the HV indicator goes out. When the vehicle is running in hybrid mode, the EV indicator goes out and the HV indicator lights up. The meter 68 is incorporated in, for example, the installation panel in front of the driver's seat.

[0025] The DCM (Data Communication Module) 70 transmits the information of the host vehicle to the traffic information management center 100 and receives the 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, and the like. Examples of the road traffic information include information regarding current and future traffic jams, information regarding the current average vehicle speed and predicted values of future average vehicle speeds in sections on the driving route, information regarding traffic regulations, information regarding weather, information regarding road surface conditions, information regarding maps, and the like. 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 current position of the 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 at predetermined times (for example, every 3 minutes, every 5 minutes, etc.) 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 obtains road traffic information from the traffic information management center 100, it generates, as pre-read information, load information necessary to drive each driving section within the driving route from among the road traffic information obtained from the traffic information management center 100, such as information on each driving section and information on driving load, the vehicle speed of the host vehicle, the driving power of the host vehicle, the driving mode of the host vehicle, etc., and transmits it to the hybrid ECU 50. Note that the pre-read information includes information on the host vehicle such as the position, vehicle speed, driving power, driving mode, etc. 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, information on maps, etc. The information on maps includes areas where motor driving should be performed (motor driving areas) defined by municipalities, etc. The navigation system 80 can also set a motor driving 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 driving area to the hybrid ECU 50 when the host vehicle is driving.

[0028] Next, the operations in the hybrid vehicle 20 configured in this way, particularly the operations when the motor driving point is reached and when the system is started up thereafter, will be described. The motor driving point is set as a point to be reached by motor driving by the user or the like. FIG. 2 is a flowchart showing an example of the driving-time processing executed by the hybrid ECU 50, and FIG. 3 is a flowchart showing an example of the system startup-time processing executed by the hybrid ECU 50. The driving-time processing in FIG. 2 is executed after the system startup processing is completed, and the system startup-time processing in FIG. 3 is executed when the ignition switch 21 is turned on at system startup. These will be described in order below.

[0029] When the running process of FIG. 2 is executed, the hybrid ECU 50 determines whether there is a motor driving point ahead (step S100). This determination can be made, for example, by determining whether a motor driving point is set up to a predetermined distance (for example, 500 m or 1000 m) ahead in the traveling direction. When it is determined that there is a motor driving point ahead, a process of calculating the distance De from the current location of the host vehicle to the motor driving point is started (step S110).

[0030] Then, it is determined whether the distance De to the motor driving point has reached the motor driving range Dref (step S120). When it is determined that the distance De to the motor driving point has reached the motor driving range Dref, the motor driving mode is set in the running mode and motor driving is started (step S130), and the motor driving history is turned on (step S140).

[0031] Next, it is determined whether the motor driving point has been reached (step S150). When it is determined that the motor driving point has been reached, the calculation of the off-road travel distance such as the travel path in the private land not recognized as a road on the map information and the update of the storage of the off-road travel distance are started (step S160).

[0032] Subsequently, it is determined whether a cancellation condition for turning off the turned-on motor driving history or resetting the off-road travel distance to the value 0 is satisfied (step S170). When it is determined that the cancellation condition is satisfied, the motor driving history is turned off, the off-road travel distance is reset to the value 0, and (step S180), the motor driving mode is stopped and set to the normal driving mode (step S185). Examples of the cancellation condition include a condition where it is determined that the motor driving point has been passed, an operation of the mode change switch 36 by the driver, or an operation of stopping the motor driving by remote control. As the condition for determining that the motor driving point has been passed, a condition where the vehicle has traveled a predetermined distance (for example, 50 m or 100 m) after passing the motor driving point can be used.

[0033] Then, it is determined whether the ignition switch 21 is turned off (IG off) (step S190). When it is determined that it is not IG off, the process returns to the process of determining whether there is a motor driving point ahead after step S100. When it is determined that it is IG off, this process ends. The IG off is performed with the motor driving history and the off-travel distance stored. Therefore, when it is IG off after the update of the storage of the off-travel distance is started, the motor driving history on is stored, and the travel distance from the motor driving point to the point where it is IG off is stored as the off-travel distance.

[0034] When it is determined in step S100 that there is no motor driving point ahead, the process proceeds to the process of determining whether the cancellation condition in step S170 is satisfied.

[0035] Now, consider the case where the home is set as the motor driving point and the vehicle is driving towards the home. The situation in this case is shown in FIG. 4. In FIG. 4, the home exists at the end of passing through a passage (the passage indicated by the broken line in the figure) within the private land that is not recognized as a road on the map. In this case, the motor driving point is set at point Pev on the road on the map. When the vehicle drives on the road on the map towards the home and reaches point P1 within the motor driving range Dref from the motor driving point Pev, the driving mode is set to the motor driving mode and the motor driving is started, and the motor driving history is turned on. After that, when the vehicle reaches the motor driving point Pev, the calculation of the off-travel distance is started and the update of the storage of the off-travel distance is started. Then, it is IG off after parking in the parking space of the home. In FIG. 4, when passing through the motor driving point Pev, driving on the broken-line passage within the private land, parking in the parking space of the home, and then IG off, the motor driving history on is stored, and the distance of the broken-line passage is stored as the off-travel distance.

[0036] The home is set as the motor driving point, but consider the case of passing through the home. Similarly in this case, when the vehicle reaches point P1 where the distance to the motor driving point Pev reaches the motor driving range Dref, the driving mode is set to the motor driving mode, motor driving is started, and the motor driving history is turned on. Also, when reaching the motor driving point Pev, the calculation of the off-driving distance is started and the update of the storage of the off-driving distance is started. Then, when reaching point P2, the cancellation condition is satisfied, the motor driving history is turned off, and the off-driving distance is reset to the value 0.

[0037] Next, the system startup process in FIG. 3 will be described. When the system startup process is executed, the hybrid ECU 50 first determines whether the motor driving history is stored as being on (step S200). When it is determined that the motor driving history is not stored as being on, the normal system startup process is performed (step S210), and this process ends.

[0038] When it is determined in step S200 that the motor driving history is stored as being on, the motor driving mode is set and motor driving is started (step S220). Then, basically, wait to drive only the off-driving distance (step S270), turn off the motor driving history and reset the off-driving distance to the value 0 (step S280), and end this process. Until driving the off-driving distance, it is determined whether a condition for temporarily stopping motor driving (temporary stop condition) is satisfied (step S230). When it is determined that the temporary stop condition is satisfied, a process of canceling the motor driving mode (step S240) is performed, and it is determined whether the temporary release condition is released (step S250). When it is determined that the temporary release condition is released, a process of returning to the motor driving mode (step S260) is repeated. Examples of the temporary release condition include the condition that the vehicle speed V becomes equal to or higher than a predetermined vehicle speed, and the condition that the state of charge SOC of the battery 40 becomes less than a predetermined state of charge (for example, 5% or 10%). Note that even if the temporary stop condition is satisfied in step S230, the motor driving history is not turned off.

[0039] Consider the case when the ignition (IG) is turned on at home as shown in Fig. 4. Since the ignition is turned on with the motor driving history on, the driving mode is set to the motor driving mode and the vehicle runs by motor driving. Also, until the vehicle runs the distance of the passageway within the private land shown by the dashed line in the figure as the off-driving distance, the motor driving mode continues. Thus, the vehicle runs by motor driving until the motor driving point Pev. After that, when the cancellation condition is satisfied, the motor driving history is turned off and the off-driving distance is reset to the value 0, and the vehicle runs in the normal driving mode.

[0040] In the hybrid vehicle 20 of the embodiment described above, when starting to run in the motor driving mode within a predetermined distance range from the motor driving point, the motor driving history is set to on. After that, when the system is started and the motor driving history is on, the vehicle runs in the motor driving mode. Therefore, even when the vehicle runs on the passageway within the private land after reaching the motor driving point and the system is stopped and then started, it is possible to run by motor driving.

[0041] In the hybrid vehicle 20 of the embodiment, when running on an off-road that is not recognized as a road on the map after reaching the motor driving point, the off-road driving distance is stored as the off-driving distance. After that, when the system is started and the motor driving history is on, the motor driving continues until running the off-driving distance from the point where the system is started. Thereby, even if the off-road driving distance after reaching the motor driving point becomes long, the motor driving can continue until running the off-road driving distance after the subsequent system start.

[0042] In the hybrid vehicle 20 of the embodiment, when the cancellation condition such as the condition determined to have passed the motor driving point or the condition that an operation to stop the motor driving is performed by the driver's operation of the mode change switch 36 or a remote operation is satisfied, the motor driving history is turned off and the off-driving distance is reset to the value 0. Thereby, it is possible to prevent the state where the motor driving history is on or the off-driving distance is not reset from continuing.

[0043] In the hybrid vehicle 20 of the embodiment, when a temporary stop condition such as a condition that the vehicle speed V becomes equal to or higher than a predetermined vehicle speed during motor running as the motor running history is on after the system is started, or a condition that the state of charge SOC of the battery 40 becomes less than a predetermined state of charge is satisfied, the motor running is temporarily canceled, and when the temporary stop condition is canceled, the vehicle returns to motor running. As a result, motor running can be performed more.

[0044] In the hybrid vehicle 20 of the embodiment, the case where the home is set as the motor running point has been described. However, the present invention can be similarly applied to the case where a point other than the home is set as the motor running point.

[0045] The correspondence relationship between the main elements of the embodiment and the main elements of the invention described in the column of means for solving the problems will be described. In the embodiment, the engine EG corresponds to the "engine", the motor MG corresponds to the "motor", the battery 40 corresponds to the "power storage device", the navigation system 80 having the map information database 84 corresponds to the "map information storage device", and the hybrid electronic control unit 50 corresponds to the "control device".

[0046] Note that the correspondence relationship between the main elements of the embodiment and the main elements of the invention described in the column of means for solving the problems is an example for specifically explaining the form for implementing the invention described in the column of means for solving the problems in the embodiment, and does not limit the elements of the invention described in the column of means for solving the problems. That is, the interpretation of the invention described in the column of means for solving the problems should be made based on the description in that column, and the embodiment is merely a specific example of the invention described in the column of means for solving the problems.
