Description

  The present invention relates to a fuel cell vehicle and a control device thereof.

  A range extender type vehicle has been proposed in which electric power generated by an engine is supplied to a motor or a secondary battery is charged (see, for example, Patent Document 1). Patent Document 1 suggests that a power generation system using a fuel cell is used instead of the engine.

Japanese Patent Application Laid-Open No. 2006-068674

  A vehicle that supplies electric power generated by a fuel cell to a motor or charges a secondary battery is called a range extender type fuel cell vehicle. Since the cost of traveling in such a vehicle is lower than that of hydrogen, there is a need to travel with electricity as much as possible (that is, to travel without driving the fuel cell as much as possible). On the other hand, in order to reduce the cost of the entire vehicle, it is desired to mount a fuel cell with a small output (for example, a small fuel cell). In particular, in this case, in order to prevent shortage of the secondary battery or to operate an inexpensive small output fuel cell at the highest efficiency output, the charge rate (SOC: State Of Charge) is high. It is preferable to drive the fuel cell. However, Japanese Patent Application Laid-Open No. H10-228707 has not studied the point of solving the trade-off related to driving of the fuel cell as described above.

  In view of such circumstances, the present invention can drive a vehicle with electricity as much as possible, and can drive the fuel cell at a timing suitable for suppressing the electric shortage of the secondary battery. An object is to provide a vehicle and a control device thereof.

  A first aspect of the present invention that solves the above problems is a fuel cell vehicle capable of charging a secondary battery by driving a fuel cell, based on the operation of the blinker of the fuel cell vehicle and the average vehicle speed, A detection unit that detects whether or not the fuel cell vehicle is traveling at a high speed; and an FC drive unit that drives the fuel cell when the SOC of the secondary battery is less than a predetermined threshold value. The FC drive unit uses a predetermined reference threshold as the threshold when it is detected that it is not under the situation, and when it is detected that the situation is based on the average vehicle speed, A fuel cell that uses a first threshold value that exceeds the reference threshold value, and uses a second threshold value that exceeds the first threshold value as the threshold value when it is detected based on the operation of the turn signal and the average vehicle speed. On the vehicle That.

  In the first aspect, when the fuel cell vehicle is traveling at a high speed, that is, when the consumption speed of the secondary battery is temporarily increased, the first threshold value and the second threshold value are used. The fuel cell can be driven at an earlier timing than when the reference threshold is used. In particular, the second threshold value is used when the average vehicle speed is high and the lane change by the turn signal indicator or the turn signal indicator is frequently used. Therefore, the fuel cell is operated at an earlier timing than when the first threshold value is used. It can be driven. On the other hand, in the first aspect, when not in the above situation, the fuel cell can be driven at a later timing than when the first threshold and the second threshold are used, using the reference threshold.

  Therefore, the first aspect satisfies the requirement that the vehicle can be driven with electricity as much as possible, and that the fuel cell can be driven at a timing suitable for suppressing the battery shortage of the secondary battery. Can do.

  In the first aspect, it is possible to detect whether or not the vehicle is in the above-described situation by a relatively simple method of operating the blinker and / or average vehicle speed. Moreover, in the first aspect, even a small fuel cell (a fuel cell that is inexpensive and has a small output) can be used for operation with the highest efficiency output. It is expected that the width will increase, and as a result, the cost of the entire vehicle can be easily reduced.

  A second aspect of the present invention is the fuel cell vehicle according to the first aspect, wherein the detection unit detects that the situation is in the state when the operation duration time of the right turn signal is equal to or greater than a predetermined value. It is in a fuel cell vehicle.

  In the second aspect, it becomes easy to catch that the consumption speed of the secondary battery is temporarily increased (for example, entering the overtaking lane or the highway). Therefore, it becomes easy to satisfy the requirement that the vehicle can be driven with electricity as much as possible and that the fuel cell can be driven at a timing suitable for suppressing the shortage of the secondary battery.

  According to a third aspect of the present invention, there is provided the fuel cell vehicle according to the first or second aspect, wherein the detection unit is configured to operate under the situation when the frequency of operation of the right turn signal and the left turn signal is equal to or higher than a predetermined value. The fuel cell vehicle detects that it is in

  In the third aspect, it is easy to catch that the consumption speed of the secondary battery is temporarily increased (for example, overtaking is repeatedly performed). Therefore, it becomes easy to satisfy the requirement that the vehicle can be driven with electricity as much as possible and that the fuel cell can be driven at a timing suitable for suppressing the shortage of the secondary battery.

  According to a fourth aspect of the present invention, there is provided the fuel cell vehicle according to any one of the first to third aspects, wherein the detection unit is configured to perform the operation when the operation duration time of the left turn signal is equal to or greater than a predetermined value. The fuel cell vehicle detects that it is not below.

  In the fourth aspect, it becomes easy to catch that the consumption speed of the secondary battery is not temporarily increased (for example, the vehicle has left the overtaking lane or the highway). Therefore, it becomes easy to satisfy the requirement that the vehicle can be driven with electricity as much as possible and that the fuel cell can be driven at a timing suitable for suppressing the shortage of the secondary battery.

  According to a fifth aspect of the present invention, there is provided the fuel cell vehicle according to any one of the first to fourth aspects, wherein the detection unit is configured such that when the average vehicle speed of the fuel cell vehicle is less than a predetermined value, The fuel cell vehicle detects that it is not under the circumstances.

  In the fifth aspect, it is understood that the consumption speed of the secondary battery is not temporarily increased (for example, the vehicle is traveling at a relatively low speed regardless of the traveling lane or road). It becomes easy. Therefore, it becomes easy to satisfy the requirement that the vehicle can be driven with electricity as much as possible and that the fuel cell can be driven at a timing suitable for suppressing the shortage of the secondary battery.

  According to a sixth aspect of the present invention, there is provided the fuel cell vehicle according to any one of the first to fifth aspects, wherein even when the FC drive unit is detected to be under the situation, the second When the consumption speed of the secondary battery is less than a predetermined value, the fuel cell vehicle uses the third threshold value less than the first threshold value.

  In the sixth aspect, even when the consumption speed of the secondary battery is temporarily increased, it is possible to prevent the fuel cell from being driven at a timing when the necessity is low. Therefore, it becomes easy to satisfy the requirement that the vehicle can be driven with electricity as much as possible and that the fuel cell can be driven at a timing suitable for suppressing the shortage of the secondary battery.

  Another aspect (seventh aspect) of the present invention that solves the above-described problems is a control device for a fuel cell vehicle capable of charging a secondary battery by driving a fuel cell, and operating the winker of the fuel cell vehicle And a detection unit that detects whether or not the fuel cell vehicle is traveling at a high speed based on each of the average vehicle speed, and when the SOC of the secondary battery is less than a predetermined threshold, the fuel cell is An FC drive unit to be driven, and when the FC drive unit is detected not to be in the situation, the FC drive unit is detected to be in the situation based on the average vehicle speed using a predetermined reference threshold as the threshold value. The first threshold value exceeding the reference threshold value is used as the threshold value, and when the situation is detected based on the operation of the turn signal and the average vehicle speed, the first threshold value is exceeded as the threshold value. The second threshold Are, the control apparatus for a fuel cell vehicle.

  In the seventh aspect, when the fuel cell vehicle is traveling at a high speed, that is, when the consumption speed of the secondary battery is temporarily increased, the first threshold value and the second threshold value are used. The fuel cell can be driven at an earlier timing than when the reference threshold is used. In particular, the second threshold value is used when the average vehicle speed is high and the lane change by the turn signal indicator or the turn signal indicator is frequently used. Therefore, the fuel cell is operated at an earlier timing than when the first threshold value is used. It can be driven. On the other hand, in the seventh aspect, when not in the above situation, the fuel cell can be driven at a later timing than when the first threshold and the second threshold are used, using the reference threshold.

  Therefore, the seventh aspect satisfies the requirement that the vehicle can be driven with electricity as much as possible, and that the fuel cell can be driven at a timing suitable for suppressing the battery shortage of the secondary battery. Can do.

  Note that in the seventh aspect, it is possible to detect whether or not the vehicle is in the above situation by a relatively simple method of operating the blinker and / or the average vehicle speed. In addition, in the seventh aspect, even a small fuel cell (a fuel cell that is inexpensive and has a small output) can be used for operation with the highest output, so that it is possible to select a usable fuel cell. It is expected that the width will increase, and as a result, the cost of the entire vehicle can be easily reduced.

  According to the present invention, the vehicle can be driven with electricity as much as possible, and the fuel cell can be driven at a timing suitable for suppressing the shortage of the secondary battery.

FIG. 6 is a diagram illustrating a configuration example of a control device according to a second embodiment.

  Hereinafter, an embodiment of the present invention will be described. About the same member, the same code | symbol is attached | subjected and description is abbreviate | omitted suitably. The scale and shape of each part in each drawing may be changed for convenience for the sake of convenience in explaining the configuration example of each part.

<Embodiment 1>
FIG. 1 shows a configuration example of a fuel cell vehicle (vehicle 1). The vehicle 1 is a so-called range extender type fuel cell vehicle capable of charging a secondary battery 3 by driving a fuel cell 2 (indicated as “FC” in the drawing).

  The vehicle 1 includes a hydrogen gas that supplies hydrogen gas to the fuel cell 2, a supply line thereof (not shown), and the like. In the fuel cell 2, power generation is performed by a chemical reaction between hydrogen and oxygen. The electric power obtained by the fuel cell 2 is supplied to the secondary battery 3, for example. The travel drive source of the vehicle 1 is a motor 4, and power is supplied to the motor 4 from, for example, the secondary battery 3. The driving (power generation) of the fuel cell 2, the SOC of the secondary battery 3, the output of the motor 4, and the like are controlled by the control device (ECU 10).

  The vehicle 1 is provided with various sensors 5. As the sensors 5, for example, a vehicle speed sensor for detecting the vehicle speed, a sensor for detecting an operation of the turn signal 6 provided in the vehicle 1 (right turn signal 6 a and left turn signal 6 b: see FIG. 2, etc.), secondary A sensor for detecting the SOC of the battery 3 or the like. Information obtained by these sensors is transmitted to the ECU 10.

  FIG. 2 shows a configuration example of a part related to the control according to the present embodiment in the ECU 10. The ECU 10 is configured around a microcomputer having a known configuration, and each part is realized by a control program of the microcomputer. The ECU 10 includes a ROM in which a control program and data information are stored in advance, a timer counter that can measure a control period, and the like.

  The ECU 10 is configured to be able to read information obtained by the sensors 5. Based on these pieces of information, the average vehicle speed V of the vehicle 1, the operation of the right turn signal 6a and the left turn signal 6b, the SOC of the secondary battery 3, and the like are derived in the ECO 10. The ECU 10 includes a detection unit 11 and an FC drive unit 12.

  The detection unit 11 detects whether or not the vehicle 1 is traveling at a high speed based on the operation of the turn signal 6 of the vehicle 1 and the average vehicle speed V. For example, when the operation duration time TR of the right turn signal 6a is equal to or greater than a predetermined value ThR, the detection unit 11 detects that the vehicle is under the above situation (for example, has entered an overtaking lane or a highway).

  Further, when the frequency F of the operation of the right turn signal 6a and the left turn signal 6b (the total number of operations of the right turn signal 6a and the operation number of the left turn signal 6b in a predetermined time) is equal to or greater than the predetermined value ThF, the detection unit 11 It is detected that it is below (for example, overtaking is repeated). Further, when the average vehicle speed V is equal to or higher than the predetermined value ThV, the detection unit 11 detects that the vehicle is under the above-described condition (for example, traveling at a high speed regardless of the travel lane or the travel road).

  On the other hand, when the operation continuation time TL of the left turn signal 6b is equal to or greater than the predetermined value ThL, the detection unit 11 detects that the above situation is not occurring (for example, the vehicle has left the overtaking lane or the highway). In addition, when the average vehicle speed V is less than the predetermined value ThV, the detection unit 11 detects that the vehicle is not in the above-described situation (for example, traveling at a low speed regardless of the travel lane or the travel road).

  The detection results of the detection unit 11 such as these are transmitted to the FC drive unit 12. Note that the detection unit 11 may be configured to only detect that it is in the above-described situation and to determine whether or not it is in the above-described situation depending on whether or not it is detected.

  The entry and / or departure from the overtaking lane or the highway as described above may be possible even with a highly accurate device such as GPS. However, since this type of device is highly accurate, it is vulnerable to communication failures and changes in the surrounding environment, so it cannot be said that it can be reliably used at any time. On the other hand, this embodiment can detect whether it is in the said situation with the comparatively simple method of operation of the blinker 6, and / or the average vehicle speed V. FIG.

  The operation of the right turn signal 6a is to turn on the turn signal 6 on the right side (that is, the overtaking lane side) of the vehicle 1 and the operation of the left turn signal 6b is the left side (that is, the movement direction of the vehicle 1). , On the opposite side of the overtaking lane). In the present embodiment, the description is given on the assumption that the right lane is an overtaking lane. However, when the left lane is an overtaking lane, the left and right descriptions of the present embodiment are reversed.

  The FC drive unit 12 drives the fuel cell 2 when the SOC of the secondary battery 3 is less than a predetermined threshold Th. Here, when the FC drive unit 12 detects that the above situation is not present (when the vehicle 1 travels at a low speed), the FC drive unit 12 uses the predetermined reference threshold value Th0 as the threshold value Th, and uses the average vehicle speed V. Is detected as the threshold value Th, the first threshold value Th1 that exceeds the reference threshold value Th0 is used as the threshold value Th, and the threshold value Th is detected as the threshold value Th when it is detected based on the operation of the blinker 6. The second threshold Th2 that exceeds the first threshold Th1 is used.

  According to this, when the vehicle 1 is traveling at a high speed, that is, when the consumption speed of the secondary battery 3 is temporarily increased, the first threshold Th1 and the second threshold Th2 are used as a reference. The fuel cell 2 can be driven at an earlier timing than when the threshold value Th0 is used. In particular, the second threshold value Th2 is used when the average vehicle speed V is high and the lane change by the blinker 6 or when the blinker 6 is frequently used, so the timing is earlier than when the first threshold value Th1 is used. The fuel cell 2 can be driven. On the other hand, when not in the above situation, the fuel cell 2 can be driven at a later timing than when the first threshold Th1 and the second threshold Th2 are used using the reference threshold Th0.

  Therefore, according to the vehicle 1 and the ECU 10, the vehicle 1 can be driven with electricity as much as possible, and the fuel cell 2 can be driven at a timing suitable for suppressing the shortage of the secondary battery 3. Moreover, according to the vehicle 1 and the ECU 10, even a small fuel cell 2 (a fuel cell 2 that is inexpensive and has a small output) can be used for driving with the highest efficiency output. The range of selection of the battery 2 is increased, and as a result, it is expected that the cost of the entire vehicle 1 can be easily reduced.

  The reference threshold value Th0, the first threshold value Th1, and the second threshold value Th2 can be appropriately set through experiments or the like. The larger the first threshold Th1 and the second threshold Th2, the more the fuel cell 2 can be driven in a situation where the vehicle 1 travels at a high speed, even though the SOC is close to the maximum value.

  Conversely, the smaller the first threshold value Th1 and the second threshold value Th2, the more the SOC is closer to the discharge end voltage in a situation where the vehicle 1 travels at a low speed, and the fuel cell 2 is driven. Can do. Conventionally, when there is a threshold value that has been used regardless of the driving lane in a so-called EV priority mode (EV priority mode) or the like, this threshold value can also be used as the reference threshold value Th0.

  FIG. 3 shows an example of the control for driving the fuel cell 2 in the control according to the present embodiment. In the figure, the vehicle 1 is traveling in the left lane.

  At time t1, the vehicle 1 operates the right turn signal 6a to enter the right lane (passing lane) in order to overtake the preceding vehicle. After the time point t1, the vehicle 1 travels at a high speed while entering the overtaking lane, so that the SOC decreasing speed becomes larger than before the time point t1.

  During the approach to the overtaking lane, the average vehicle speed V becomes equal to or greater than the predetermined value ThV, and the operation duration time TR of the right turn signal 6a becomes equal to or greater than the predetermined value ThR at time t2. At this time, not the reference threshold Th0 but the second threshold Th2 is selected as the threshold Th. As a result, the SOC of the secondary battery 3 becomes less than the second threshold Th2 (time t3) at a timing earlier than when the reference threshold Th0 is used (see the dashed line in the figure: time t4), and as a result, the fuel cell 2 can be driven. Electron deficiency can be suitably prevented even against a sudden decrease in SOC expected thereafter.

  Although FIG. 3 is an example in which the vehicle 1 enters the overtaking lane, for example, the same applies to the case of entering an expressway. During the approach to the highway, the average vehicle speed V becomes equal to or higher than the predetermined value ThV, and the operation duration time TR of the right turn signal 6a becomes equal to or longer than the predetermined value ThR. At this time, the threshold Th is switched to the second threshold Th2. Therefore, the fuel cell 2 can be driven at an earlier timing than when the reference threshold Th0 is used.

  Although not shown, the average vehicle speed V becomes equal to or higher than the predetermined value ThV when the vehicle 1 is traveling at a relatively high speed regardless of the lane or road on which the vehicle is traveling. Even if does not correspond to the above, the threshold Th is switched to the first threshold Th1. Therefore, the fuel cell 2 can be driven at an earlier timing than when the reference threshold Th0 is used.

  Although not shown, if the vehicle 1 repeatedly overtakes another vehicle, the average vehicle speed V becomes a predetermined value ThV or more, and the operation frequency F of the right turn signal 6a and the left turn signal 6b becomes a predetermined value ThF or more. Therefore, at this time, the threshold value Th is switched to the second threshold value Th2. Therefore, the fuel cell 2 can be driven at an earlier timing than when the reference threshold Th0 is used.

  FIG. 4 shows an example of control for stopping the driving of the fuel cell 2 in the control according to the present embodiment. In the figure, the vehicle 1 is traveling in the right lane. The second threshold value Th2 is selected as the threshold value Th, and the fuel cell 2 has already been driven.

  At time t1, the vehicle 1 that overtakes the preceding vehicle enters the left lane and operates the left turn signal 6b (time t1a). After time t1a, the vehicle 1 continues to travel at a high speed in order to overtake other vehicles. Since the power of the secondary battery 3 is greatly consumed, the SOC gradually decreases despite the fuel cell 2 being driven.

  While entering the left lane, at the time t2a, the average vehicle speed V becomes less than the predetermined value ThV, and the operation duration time TL of the left turn signal 6b becomes equal to or greater than the predetermined value ThL. At this time, the reference threshold Th0 is selected as the threshold Th instead of the second threshold Th2. As a result, the SOC of the secondary battery 3 becomes equal to or higher than the threshold value Th, and the driving of the fuel cell is stopped, so that the rate of decrease in the SOC becomes greater after time t2a than before time t2a.

  However, at time t3a shortly after time t2a, the vehicle 1 has entered the left lane, and thus travels at high speed. Accordingly, the SOC decrease rate becomes lower than the rate during the period from the time point t2a to the time point t3a. That is, even if the driving of the fuel cell 2 is stopped, the driving environment can be suitably run, and then the fuel cell 2 is driven at a timing according to the reference threshold Th0. Thus, the fuel cell 2 can be driven at a timing earlier than when the second threshold Th2 is used.

  Although not shown, the average vehicle speed V is less than the predetermined value ThV when the vehicle 1 is traveling at a relatively low speed regardless of the lane or road on which the vehicle is traveling. Switches to the reference threshold Th0.

  In the vehicle 1 and the ECU 10 described above, when the vehicle 1 is traveling at a high speed, that is, when the consumption speed of the secondary battery 3 is temporarily increased, the first threshold value Th1 and the second threshold value Th2 are used. , The fuel cell 2 can be driven at an earlier timing than when the reference threshold Th0 is used. In particular, the second threshold value Th2 is used when the average vehicle speed V is high and the lane change by the blinker 6 or when the blinker 6 is frequently used, so the timing is earlier than when the first threshold value Th1 is used. The fuel cell 2 can be driven. On the other hand, when the vehicle 1 and the ECU 10 are not in the above situation, the fuel cell 2 can be driven at a later timing than when the second threshold Th2 is used using the reference threshold Th0.

  Therefore, the vehicle 1 and the ECU 10 can travel the vehicle 1 with electricity as much as possible, and can drive the fuel cell 2 at a timing suitable for suppressing the shortage of the secondary battery 3.

  Note that the vehicle 1 and the ECU 10 can detect whether or not the vehicle is in the above-described state by a relatively simple method of operating the turn signal 6 and / or the average vehicle speed V. Further, in the vehicle 1 and the ECU 10, even a small fuel cell 2 (a fuel cell 2 that is inexpensive and has a small output) can be used for driving with the highest efficiency output. As a result, it is expected that the cost of the entire vehicle 1 can be easily reduced.

<Embodiment 2>
FIG. 5 shows a configuration example of a portion related to control according to the present embodiment in the ECU 10A of the vehicle 1A. The ECU 10 </ b> A calculates the consumption speed Ve of the secondary battery 3 based on the information obtained by the sensors 5. The ECU 10A includes a detection unit 11 and an FC drive unit 12A. Among these, the detection part 11 is the same as that of Embodiment 1.

  Even when the detection unit 11 detects that the FC driving unit 12A is in the above-described state (when the vehicle 1A travels at a high speed), the FC driving unit 12A is the first when the consumption speed Ve of the secondary battery 3 is less than the predetermined value ThVe. A third threshold Th3 that is less than the threshold Th1 is used.

  For example, there is a case where the vehicle 1A temporarily travels at a high speed near the home. In such a case, it is not necessary to drive the fuel cell 2 and charge the secondary battery 3. According to the vehicle 1A and the ECU 10A, even when the consumption speed Ve of the secondary battery 3 is temporarily increased, it is possible to prevent the fuel cell 2 from being driven at a timing when the necessity is low. it can.

  Note that the third threshold Th3 can be set as appropriate through experiments or the like. The third threshold Th3 may be equal to or greater than the reference threshold Th0 or the same value as the reference threshold Th0.

<Other embodiments>
The embodiment of the present invention has been described above. However, each of the above embodiments is an aspect of the present invention, and additions, omissions, substitutions, and other modifications of the configuration can be made without departing from the spirit of the present invention. For example, a part or all of the second embodiment can be combined with the first embodiment.

  For example, the vehicle 1 may temporarily travel at a high speed on the way to the charging station. In such a case, it is not necessary to drive the fuel cell 2 and charge the secondary battery 3. Therefore, the ECU 10A of the second embodiment exchanges signals with neighboring charging stations and detects that there is an available charging station nearby, and at this time, the consumption speed Ve of the secondary battery 3 temporarily increases. Even under circumstances, the third threshold Th3 can be used. This also prevents the fuel cell 2 from being driven in a situation where it is unlikely that the fuel cell 2 is purposely driven to charge the secondary battery 3 as in the second embodiment.
