- the shift switching mechanism 48 will be described with reference to FIG. FIG. 2 shows the configuration of the shift switching mechanism 48.
- the shift range means the P range and the non-P range, and does not include the R, N, D, and B ranges in the non-P range.
- the shift switching mechanism 48 is connected to the actuator 45 through the shaft 102 and rotates with the rotation of the actuator 45, the rod 104 that operates with the rotation of the detent plate 100, and the output shaft of the transmission (not shown).
- a parking gear 108 fixed to the parking gear 108, a parking lock pole 106 for locking the parking gear 108, a detent spring 110 and a roller 112 for restricting the rotation of the detent plate 100 to a predetermined range and fixing the shift range.

- the shaft 102, the detent plate 100, the rod 104, the detent spring 110, and the rollers 112 serve as a shift switching mechanism.
- FIG. 2 shows a state when the shift range is the non-P range. In this state, since the parking lock pole 106 does not lock the parking gear 108, the rotation of the drive shaft of the vehicle is not hindered.
- the shaft 45 is rotated clockwise by the actuator 45 from this state, the rod 104 is pushed in the direction of the arrow A shown in FIG. 2 via the detent plate 100, and parking is performed by the tapered portion provided at the tip of the rod 104.

- the roller 112 is provided on the detent spring 110 so as to be rotatable in its axial direction.
- the detent plate 100 rotates until the roller 112 reaches the P range position 124, the parking lock pole 106 is pushed up to a position where it engages with the parking gear 108.
- the drive shaft of the vehicle is mechanically fixed, and the shift range is switched to the P range.
- FIG. 3 shows the configuration of the detent plate 100.
- a P wall 200 and a non-P wall 210 are provided on the surfaces located on the side away from the mountain 122 at the P range position 124 and the non-P range position 120, respectively.
- the rotation of the detent plate 100 (that is, the rotation of the actuator 45) is restricted by the P wall 200 and the non-P wall 210 colliding with the roller 112.
- FIG. 4 is a diagram for explaining the P range determination process performed by the P-ECU 40.
- the P range determination process is a process for actually detecting that the shift range is the P range.
- FIG. 4 conceptually shows the position of the P wall 200 when the P-ECU 40 performs the P range determination process.
- the range from the P wall position to the non-P wall position shown in FIG. 4 is the movable rotation range of the actuator 45.
- the P-ECU 40 sets the P lock determination position at a position away from the P wall position by a predetermined range. Then, P-ECU 40 determines that the shift range is the P range when the relative position of actuator 45 to the P wall position is included in the range between the P wall position and the P lock determination position.
- the P wall position becomes a reference position for actually detecting that the shift range is the P range by the P range determination process. Therefore, in order to determine that the shift range is the P range by the P range determination process, it is necessary to detect the P wall position.
- the encoder 46 can detect the relative position of the actuator 45, but cannot detect the absolute position of the actuator 45.
- the P-ECU 40 performs control to rotate the actuator 45 and press the P wall 200 against the roller 112 (hereinafter also referred to as “P wall contact control”), and the actuator detected by the encoder 46 during the P wall contact control.
- the P wall position is detected using 45 relative positions.
- the shift range is set to the P range by executing this P wall contact control.
- FIG. 5 is a diagram for explaining the P wall contact control performed to detect the P wall position.
- the P-ECU 40 causes the actuator 45 to rotate the detent plate 100 in the clockwise direction, that is, the direction in which the P wall 200 faces the roller 112 of the detent spring 110, thereby bringing the P wall 200 into contact with the roller 112.
- the roller 112 restricts the clockwise rotation of the actuator 45 at the P range position.
- an arrow F ⁇ b> 1 indicates a rotational force by the actuator 45
- an arrow F ⁇ b> 2 indicates a spring force by the detent spring 110
- an arrow F ⁇ b> 3 indicates a push-back force by the rod 104.
- a detent plate 100A indicated by a dotted line indicates a position where the P wall 200 and 112 are in contact with each other. Therefore, detecting the position of the detent plate 100A corresponds to detecting the P wall position.
- the detent plate 100 is rotated against the spring force of the detent spring 110 in the clockwise direction by the rotational force F1 of the actuator 45 from the position indicated by the dotted line even after contact with the P wall 200 and 112. As a result, the detent spring 110 is deflected, the spring force F2 is increased, and the pushing back force F3 by the rod 104 is also increased. The rotation of the detent plate 100 stops when the rotational force F1 is balanced with the spring force F2 and the pushing back force F3.
- the rotation stop of the detent plate 100 is determined based on the detection value of the encoder 46 (relative position of the actuator 45). Specifically, when the detection value of the encoder 46 does not change for a predetermined time, it is determined that the rotation of the detent plate 100 and the actuator 45 has stopped.
- the P-ECU 40 detects the position of the detent plate 100 when the rotation is stopped as a provisional P wall position (hereinafter also referred to as “provisional P wall position”), and calculates a deflection amount or a deflection angle of the detent spring 110. .
- provisional P wall position a provisional P wall position
- the calculation of the deflection amount or the deflection angle is performed using a map that is held in advance in the P-ECU 40 and shows the relationship between the deflection amount or the deflection angle corresponding to the voltage applied to the actuator 45.
- the P-ECU 40 calculates a deflection amount or a deflection angle corresponding to a voltage applied to the actuator 45 when the temporary P wall position is detected from the map.
- the P-ECU 40 corrects the temporary P wall position from the calculated deflection amount or deflection angle, and determines the corrected position as the P wall position. By determining the P wall position, the P lock determination process can be performed. Note that the method for calculating the deflection amount or the deflection angle of the detent spring 110 is not particularly limited to using the map described above.
- the actuator 45 is rotated to bring the P wall 200 of the detent plate 100 and the roller 112 of the detent spring 110 into contact with each other. Then, the P wall position is detected by detecting the contact position.
- this P wall position as a reference position, it is possible to properly grasp the rotational position of the actuator 45 even if an encoder 46 that can detect only relative position information is used, and the shift range is actually the P range. Can be detected.
- the P-ECU 40 is activated not only when the user performs the IG on operation, but also by an external factor such as a leak check after the IG is turned off. Therefore, if the P wall contact control is performed every time the P-ECU 40 is activated, the number of executions of the P wall contact control, that is, the number of times the P wall 200 is pressed against the rollers 112 increases, and the durability of the components of the shift switching mechanism 48 increases. Can get worse.
- the P-ECU 40 determines whether its own starting is due to an IG on operation or an external factor, and is based on an IG on operation. In this case, the P wall contact control is executed, and when the activation is based on an external factor, the P wall contact control is not executed. This is the most characteristic point of the present invention.

- the arithmetic processing unit 42 includes an initial drive unit 42A, an IG determination unit 42B, a wall contact control unit 42C, a maintenance control unit 42D, and a standby control unit 42E.
- the initial drive unit 42A performs initial drive control when the P-ECU 40 is activated (when power is supplied from the power source 54 to the P-ECU 40). Specifically, the initial drive unit 42A starts energization of the actuator 45 when the P-ECU 40 is activated, and performs initial drive of the actuator 45 until a predetermined time T1 elapses from the start of energization.
- the predetermined time T1 is stored in advance in the storage unit 43 as a time required for completing the initial drive.
- the IG determination unit 42B determines whether the activation of the P-ECU 40 is an activation due to an IG on operation by the user or an activation due to an external factor. Specifically, the IG determination unit 42B determines whether or not at least one of the IG (LIN) signal and the IG (CAN) signal is received. The determination whether or not the IG signal is received is continued until the predetermined time T2 elapses from the completion of the initial drive control until the IG signal is determined to be received, and the predetermined time T2 elapses. However, if it is not determined that the IG signal has been received, the process is terminated when the predetermined time T2 has elapsed. The predetermined time T2 is set in advance and stored in the storage unit 43 in consideration of the communication delay of the IG (LIN) signal or the IG (CAN) signal.
- the wall contact control unit 42C When the wall contact control unit 42C receives the IG signal from the completion of the initial drive control until the predetermined period T2 elapses, the wall contact control unit 42C determines that the activation of the P-ECU 40 is the activation by the IG ON operation, and the IG signal The wall-to-wall control is executed when it is received. In addition, after completion of P wall contact control, it transfers to normal mode.
- the maintenance control unit 42D temporarily maintains the actuator 45 in the state where the initial drive control is completed when the IG signal has not been received yet when the initial drive control is completed. Then, the maintenance control unit 42D continues to temporarily maintain the actuator 45 in the state where the initial drive control is completed until the IG signal is received from when the initial drive control is completed until the predetermined period T2 elapses. To do.
- the standby control unit 42E performs the initial standby control when the IG signal is not received even after the predetermined period T2 has elapsed from the completion of the initial drive control. Specifically, the standby control unit 42E cuts off the power supply to the actuator 45 and returns the actuator to the initial standby state before the initial drive control.
- FIG. 7 is a processing flow of the P-ECU 40 when the above-described functions are realized by software. This process is executed when the P-ECU 40 is activated.
- step (hereinafter abbreviated as S) 100 P-ECU 40 starts the above-described initial drive control.
- the P-ECU 40 determines whether or not the initial drive control is completed. This determination is made based on whether or not a predetermined time T1 has elapsed since the start of the initial drive control. If a positive determination is made in this process (YES in S102), the process proceeds to S104. Otherwise (NO in S102), the process returns to S102 and is repeated until a predetermined time T1 has elapsed. Note that an initial drive completion flag (a flag indicating that the initial drive has been completed) is turned on when a predetermined time T1 has elapsed since the start of the initial drive control.
- P-ECU 40 determines whether or not at least one of the IG (LIN) signal and the IG (CAN) signal has been received. If a positive determination is made in this process (YES in S104), the process proceeds to S106. Otherwise (NO in S104), the process proceeds to S108. If neither the IG (LIN) signal nor the IG (CAN) signal is received when the initial drive is completed, a timer for counting a predetermined time T2 is started from the completion of the initial drive.
- the P-ECU 40 executes the above-described P wall contact control. In addition, after the completion of the P wall contact control, the mode is shifted to the normal mode.
- the P-ECU 40 determines whether or not a predetermined time T2 has elapsed since the completion of the initial drive control. If a positive determination is made in this process (YES in S108), the process proceeds to S112. Otherwise (NO in S108), the process proceeds to S110.
- the P-ECU 40 temporarily maintains the actuator 45 in a state where the initial drive control is completed. Thereafter, the process returns to S104.
- the P-ECU 40 performs the initial standby control described above. Note that, along with the start of the initial standby control, the initial drive completion flag is turned off and the initial drive transition prohibition flag (flag indicating prohibition of transition to the initial drive mode) is turned on.
- FIG. 8 is a diagram showing a temporal change in the actuator control mode when the P-ECU 40 is activated by an external factor.
- the P-ECU 40 is also activated accordingly. With the activation of the P-ECU 40, the P-ECU 40 starts energizing the actuator 45 and performs the initial drive of the actuator 45 until time t2 when a predetermined time T1 elapses. At time t2, the initial drive control is completed and the initial drive completion flag is turned on.
- the P-wall contact control is started at the time t2 when the initial drive control is completed, as indicated by the one-dot chain line.
- P-ECU 40 does not receive either the IG (LIN) signal or the IG (CAN) signal at time t2 (OFF) (NO in S104). Is activated in response to the activation of the V-ECU 30 for the leak check, and the actuator 45 is temporarily maintained in the state where the initial drive has been completed without shifting to the P wall contact control (S108). NO, S110).
- the P-ECU 40 when the activation of the P-ECU 40 is not an activation due to the IG ON operation but an activation due to an external factor (activation according to the activation of the V-ECU 30 for leak check), Since it is not necessary to perform the confirmation process, the P-ECU 40 does not execute the P wall contact control. Therefore, the number of executions of the P wall contact control can be reduced and the deterioration of the durability of the components of the shift switching mechanism 48 can be suppressed as compared with the case where the P wall contact control is performed every time the P-ECU 40 is activated. .
- the P-ECU 40 cuts off the power supply to the actuator 45 at time t3. Then, the actuator 45 is returned to the initial standby state (NO in S104, YES in S108, S112). This prevents the energization of the actuator 45 from being continued, so that the thermal durability of the actuator 45 is improved.
- FIG. 9 is a diagram showing a temporal change in the actuator control mode at the normal start-up by the IG-on operation.
- a plurality of electric devices including the P-ECU 40 are activated.
- the P-ECU 40 starts energizing the actuator 45 and performs the initial drive of the actuator 45 until time t5 when a predetermined time T1 elapses.
- the IG (LIN) signal from the PM-ECU 50 and the IG (CAN) signal from the B-ECU 60 are received by the P-ECU 40 with a slight delay from time t4.
- the P-ECU 40 starts the initial drive from time t4, and determines whether the IG (LIN) signal and the IG (CAN) signal are received at time t5 when the initial drive is completed (S102). YES, S104). For this reason, it is possible to start the initial drive earlier than in the case where the initial drive is started after the reception determination of the IG signal.
- FIG. 10 also shows the temporal change of the actuator control mode at the normal startup by the IG on operation.
- the P-ECU 40 is activated, and at time t8, which is from when the initial driving is completed until a predetermined time T2 has elapsed (from time t7 to t9), IG (CAN ) Shows a temporal change of the actuator control mode when a signal is received.
- the IG signal is not received at time t7 when the initial drive is completed, but if the predetermined time T2 has not elapsed (NO in S108), the actuator 45 is temporarily maintained in the state where the initial drive is completed. (S110). Therefore, even if the IG (CAN) signal is received at the subsequent time t8 due to the influence of communication delay or the like, the IG (CAN) signal is received at the time t8 from the time t8 without performing the initial drive again. At that time, the P wall contact control can be started at an early stage.
- the P-ECU determines whether its own activation is an activation due to an IG on operation or an activation due to an external factor.
- the wall contact control is executed, and the P wall contact control is not executed when the activation is caused by an external factor. Therefore, the number of executions of the P wall contact control can be reduced and the deterioration of the durability of the components of the shift switching mechanism 48 can be suppressed as compared with the case where the P wall contact control is performed every time the P-ECU 40 is activated. .
- FIG. 11 is a functional block diagram of the V-ECU 30 according to the present embodiment.
- V-ECU 30 includes an input interface 31, a calculation processing unit 32, a storage unit 33, and an output interface 34.
- the storage unit 33 stores various types of information, programs, threshold values, maps, and the like, and data is read or stored from the arithmetic processing unit 32 as necessary.
- the arithmetic processing unit 32 performs arithmetic processing based on information from the input interface 31 and the storage unit 33.
- the processing result of the arithmetic processing unit 32 is output to each device via the output interface 34.
- the calculation processing unit 32 includes a permanent holding unit 32A, an abnormality detection unit 32B, a determination unit 32C, a first permission unit 32D, and a second permission unit 32E.
- the permanent holding unit 32A has a permanent holding function of the main relay 35. Specifically, the permanent holding unit 32A permanently holds the main relay 35 when the IG is off and the N range is set.
- “permanent holding” means that the main relay 35 is always kept on. Thereby, the V-ECU 30 and the P-ECU 40 are maintained in the activated state. Note that the PM-ECU 50 may have this permanent holding function.
- the vehicle 10 is provided with a function of switching the vehicle state to the IG off state when the user keeps pressing the start switch 28 for a long time while the vehicle is running when the IG is on. This is a fail-safe function for allowing the user to appropriately reduce the driving force even when an abnormality occurs in the hybrid system.
- P shift range to P range
- the main relay 35 is permanently held, and the P-ECU 40 that performs P-locking is maintained in the activated state. This is the reason why the main relay 35 needs to be kept permanently. Note that the main relay 35 may be permanently held in the case of “IG off” and “non-P range”.
- the abnormality detection unit 32B has a function of detecting a response abnormality of the P-ECU 40. Specifically, the abnormality detection unit 32B transmits a request for switching to the P range (or a request for switching to the non-P range) to the P-ECU 40, and a response indicating that the P range is from the P-ECU 40. Is not received, it is determined that the response of the P-ECU 40 is abnormal.
- the P-ECU 40 does not execute the P wall contact control at the time of activation due to an external factor. At this time, if the V-ECU 30 permits the permanent holding function of the main relay 35 and the abnormality detection function of the V-ECU 30, Problems arise.
- the vehicle is originally in the IG off state and the P-ECU 40 does not execute the P wall contact control (the shift range is not necessarily P lock).
- the range is the N range
- the condition “IG off and N range” is satisfied.
- the main relay 35 cannot be turned off although it is not necessary to perform the P lock.
- the P-ECU 40 when the P-ECU 40 is activated by an external factor, the P-ECU 40 does not execute the P wall contact control, and therefore does not perform the P range determination process and the control of the actuator 45 thereafter. Even if the V-ECU 30 transmits a request for switching to the P range to the P-ECU 40 in such a state, the P-ECU 40 cannot switch to the P range and the V-ECU 30 is in the P range. Can't send a response. Therefore, although the P-ECU 40 is normal, it is erroneously determined that the P-ECU 40 is abnormal in response.
- the V-ECU 30 allows the permanent holding of the main relay 35 and the V-ECU 40 when the P-ECU 40 cannot execute the P wall contact control because the activation of the P-ECU 40 is an external factor. -The abnormality detection of the ECU 30 is not performed. This function is realized by the determination unit 32C, the first permission unit 32D, and the second permission unit 32E.
- the determination unit 32C determines whether the activation of the P-ECU 40 is due to an external factor. For example, the determination unit 32C determines that the current IG state signal is OFF, there is no IG ON history during the current trip, and that the current V-ECU 30 is activated due to an external factor (for leak check) In the case of activation), it is determined that activation of the P-ECU 40 is activation due to an external factor.
- 1st permission part 32D permits execution of the permanent retention function of main relay 35 by permanent retention part 32A, when activation of P-ECU 40 is not the activation by an external factor. Specifically, the permanent holding mask flag is set to “off”. On the other hand, when the activation of the P-ECU 40 is an activation due to an external factor, the first permission unit 32D prohibits the permanent holding function of the main relay 35 by the permanent holding unit 32A. Specifically, the permanent holding mask flag is turned “ON”.
- the second permission unit 32E permits the abnormality detection unit 32B to execute the abnormality detection function of the P-ECU 40. Specifically, the abnormality detection mask flag is set to “off”. On the other hand, when the activation of the P-ECU 40 is an activation due to an external factor, the second permission unit 32E prohibits the abnormality detection unit 32B from executing the abnormality detection function of the P-ECU 40. Specifically, the abnormality detection mask flag is turned “ON”.
- FIG. 12 is a processing flow of the V-ECU 30 when the functions of the determination unit 32C, the first permission unit 32D, and the second permission unit 32E described above are realized by software. This process is executed in a predetermined cycle when the IG is on.
- V-ECU 30 determines whether or not the current IG state signal is OFF. If a positive determination is made in this process (YES in S200), the process proceeds to S202. Otherwise (NO in S200), the process proceeds to S210.
- V-ECU 30 determines whether there is no history of IG on during the current trip. If a positive determination is made in this process (YES in S202), the process proceeds to S204. Otherwise (NO in S202), the process proceeds to S210.
- the V-ECU 30 determines whether or not the current activation of the V-ECU 30 is an activation due to an external factor (activation for leak check). If a positive determination is made in this process (YES in S204), the process proceeds to S206. Otherwise (NO in S204), the process proceeds to S210.
- the V-ECU 30 prohibits execution of the permanent holding function of the main relay 35 described above. Specifically, the V-ECU 30 sets the permanent holding mask flag to “ON”. Note that the permanent holding mask flag is set to “off” in the initial state.
- the V-ECU 30 prohibits execution of the abnormality detection function of the P-ECU 40. Specifically, the abnormality detection mask flag is turned “ON”. Note that the abnormality detection mask flag is set to “off” in the initial state.
- the V-ECU 30 permits execution of the permanent holding function described above. Specifically, the V-ECU 30 sets the permanent retention mask flag to “off”.
- the V-ECU 30 permits execution of the abnormality detection function of the P-ECU 40 described above. Specifically, the abnormality detection mask flag is set to “off”.
- V-ECU 30 The operation of the V-ECU 30 according to this embodiment based on the above-described structure and flowchart will be described with reference to FIGS. 13 and 14, the operation in which the V-ECU 30 sets the permanent holding mask flag will be described.
- FIG. 13 shows a permanent holding mask flag when the user traveling on the vehicle presses the start switch 28 for a long time.
- FIG. 13 shows a case where the IG is turned off by pressing and holding the start switch 28 at time t11 (actually, the accessory state (ACC state) is set) and the shift range is the N range.
- the IG is off (YES in S200), but since there is an IG on history (NO in S202), the permanent holding mask flag is “off” (S210). Therefore, as shown in FIG. 13, the permanent holding function is activated at time t11, and the permanent holding request is turned on. As a result, since the P-ECU 40 is maintained in the activated state, the P lock can be applied even after that.
- FIG. 14 shows a permanent holding mask flag when the V-ECU 30 is activated for a leak check.
- the IG is off (YES at S200), and there is no IG on history (NO at S202), and the current activation of V-ECU 30 is the activation by an external factor. (YES in S204), the permanent holding mask flag is turned “ON” (S206).
- the V-ECU 30 when the activation factor of the P-ECU 40 is the IG on operation, the V-ECU 30 according to the present embodiment permanently holds the main relay 35 when “IG off and N range”. As a result, it is avoided that the P lock cannot be performed when the IG is turned off by the fail safe function.
- the activation factor of P-ECU 40 when the activation factor of P-ECU 40 is an external factor, V-ECU 30 does not permanently hold main relay 35 even in the “IG off and N range”. As a result, it is possible to avoid that the main relay 35 cannot be turned off when the P-ECU 40 is activated for a leak check, and it is possible to prevent the power of the power source 54 from being wasted.
- the V-ECU 30 does not detect the abnormality of the V-ECU 30 when the P-ECU 40 cannot execute the P wall contact control because the activation of the P-ECU 40 is an external factor. . Therefore, it is possible to prevent the V-ECU 30 from erroneously determining that the P-ECU 40 is normal even though the P-ECU 40 is normal.

Abstract
Description

図2は、シフトレンジが非Pレンジであるときの状態を示している。この状態では、パーキングロックポール106がパーキングギア108をロックしていないので、車両の駆動軸の回転は妨げられない。この状態からアクチュエータ45によりシャフト102を時計回り方向に回転させると、ディテントプレート100を介してロッド104が図2に示す矢印Aの方向に押され、ロッド104の先端に設けられたテーパ部によりパーキングロックポール106が図2に示す矢印Bの方向に押し上げられる。また、ディテントプレート100の頂部に設けられた2つの谷のうちの一方である非Pレンジ位置120に存在していたディテントスプリング110のころ112は、ディテントプレート100の時計回り方向の回転に伴って、山122を乗り越えて他方の谷であるPレンジ位置124へ移る。ころ112は、その軸方向に回転可能にディテントスプリング110に設けられている。ころ112がPレンジ位置124に来るまでディテントプレート100が回転したとき、パーキングロックポール106は、パーキングギア108と嵌合する位置まで押し上げられる。これにより、車両の駆動軸が機械的に固定され、シフトレンジがPレンジに切り換わる。
以下、本発明の第2の実施例に係る制御装置について説明する。本実施例においては、前述の第1の実施例に比べて、以下に述べるV-ECU30の機能が追加されている。その他の構造、機能、処理は、前述の第1の実施例と同じであるため、ここでの詳細な説明は繰返さない。
記憶部33は、各種情報、プログラム、しきい値、マップ等が記憶され、必要に応じて演算処理部32からデータが読み出されたり格納されたりする。
