- step S30 determines whether the predetermined period t3 has elapsed. If the determination result in step S30 is true (Yes) and it is determined that the predetermined period t3 has elapsed, the gear is not disengaged while the clutch device 3 is connected for some reason. It is considered a situation. As such a situation, for example, it is conceivable that the parameter is not accurate and the engine torque Te is not correctly obtained in the above equation (5), or that the rack position sensor 9 is abnormal. . Accordingly, in this case, the process proceeds to step S32, in which the clutch device 3 is operated to automatically disengage the clutch device 3 (automatic clutch disengagement), and then proceed to step S34.
- step S34 it is determined whether or not a predetermined period t4 has elapsed after the clutch device 3 was automatically disengaged.
- the predetermined period t4 is, for example, a time that exceeds the response delay of the clutch actuator 16 and the clutch device 3 is normally disconnected until the predetermined period t4 elapses, and the gear is disengaged. Should be. Therefore, until the determination result is false (No) and the predetermined period t4 has elapsed, the determination in step S18 is continued and the gear is disengaged and waited.
- step S34 determines whether the transmission 4 is out of order. If the result of the determination in step S34 is true (Yes) and it is determined that the predetermined period t4 has elapsed, it is considered that gear removal itself cannot be achieved due to some factor. Therefore, in this case, it is determined that the transmission 4 is out of order, the process proceeds to step S36, all the automatic transmission control is stopped, and the warning lamp 83 is turned on. And inform the driver of the malfunction.
- step S18 If the result of the determination in step S18 is true (Yes) and it is determined that the gear has been disengaged, the process proceeds to step S20.
- step S20 it is determined whether or not the clutch device 3 is automatically disengaged. If the result of the determination is false (No) and the clutch device 3 has not been automatically disengaged, the flow proceeds to step S24. On the other hand, if the clutch device 3 is automatically disconnected as described above, the determination result is true (Yes), and in this case, the connection operation of the clutch device 3 is performed in step S22. Thereafter, the process proceeds to step S24.
- step S24 the process waits for a predetermined period t2 to elapse, and then in step S26, the engine speed Ne feedback control (Ne-FZB control) is performed.
- the engine speed Ne feedback control (Ne-FZB control) is performed.
- the engine rotational speed Ne is substantially synchronized with the gear rotational speed at the gear after the shift.
- step S40 it is determined whether or not within a predetermined period t5 after the start of the Ne-FZB control. Immediately after the Ne—F / B control is started, the determination result is true (Y e s), and the process proceeds to step S42.
- the gear rotation speed in the gear after the gear shift, that is, the target Ne is a rotation speed sensor.
- step S44 It is easily calculated from the rotation speed of the output shaft 76 and the gear ratio detected by the gear 78 (gear rotation speed detecting means). If the result of the determination is false (No) and it is determined that the engine speed Ne is not at or near the target Ne after shifting, the flow proceeds to step S44.
- step S44 it is determined whether or not the engine rotation speed Ne is within a range of a rotation speed higher than the target Ne after the shift by a predetermined value N2 (Ne ⁇ target Ne + N2). If the determination result is false (No), it can be determined that the engine speed Ne is too high. In this case, the process proceeds to step S46, and the auxiliary brake is turned on. Specifically, the exhaust brake 52 is closed to lower the engine speed Ne.
- step S44 determines whether the engine speed Ne is not so high. In this case, the process proceeds to step S48, the auxiliary brake is turned off, and the Go to S50.
- step S50 When controlling the engine speed Ne to be the target Ne, if this target Ne is instructed directly to the engine 1, depending on the engine characteristics, it may take time for the engine speed Ne to reach the target Ne, The deviation between the speed Ne and the target Ne may remain. Therefore, in step S50, a target Ne correction instruction is issued, and engine control is performed so that the corrected target Ne is obtained. As a result, the engine speed Ne can be controlled to the target Ne in a short time without deviation.
- step S42 determines whether or not. If the result of the determination in step S42 is true (Yes) and it is determined that the engine speed Ne is at or near the target Ne after the shift, that is, if the engine speed Ne is the gear position after the shift, If it is determined that the target Ne is substantially synchronized with the target Ne in step S52, the process proceeds to step S52 to turn off the auxiliary brake, and in step S54, a predetermined period t6 has elapsed after the start of the Ne-FZB control. It is determined whether or not.
- step S54 determines whether the determination result in step S54 is false (No) and the predetermined period t6 has not yet elapsed
- the target Ne is instructed in step S56, and if the determination result is true (Yes) and the predetermined period t6 If the time has elapsed, or if the determination result in step S40 is false (No) and the predetermined period t5 has elapsed, the Ne-FZB control ends, and the flow advances to step S28 in FIG.
- step S28 the auxiliary brake is turned off again, and the process proceeds to step S60 in FIG.
- step S60 the engine speed Ne is changed to the target Ne in the gear stage after the shift.
- a gear shift (gear shift) instruction is given. If the engine speed Ne is substantially synchronized with the target Ne in the gear position after the gear change, the gears should enter smoothly without disengaging the clutch device 3. Therefore, here, the gear shift (gear engagement) is performed by the gear shift unit 64 while the flywheel 10 and the clutch plate 12 are connected without disconnecting the clutch device 3.
- step S62 it is determined whether the gear shift has been completed.
- the process proceeds to step S64 to determine whether or not a predetermined period t7 has elapsed after instructing the gear shift.
- the predetermined period t7 is a time exceeding the response delay of the shift fork, for example, similarly to the above-mentioned predetermined period t3, and the gear should normally be engaged before the predetermined period t7 elapses. Therefore, until the determination result is false (No) and the predetermined period t7 elapses, the determination in step S62 is continued and the gear is turned on.
- step S64 determines whether the transmission 4 is out of order. If the determination result of step S64 is true (Yes) and it is determined that the predetermined period t7 has elapsed, it is considered that the gear shift itself cannot be achieved due to some factor. Therefore, in this case, it is determined that the transmission 4 is out of order, the process proceeds to step S66, the shift instruction is stopped, the warning lamp 83 is turned on, and the driver is notified of the outage.
- step S62 determines whether the gear shift has been completed. If the result of the determination in step S62 is true (Y e s) and it is determined that the gear shift has been completed, the flow proceeds to step S68.
- step S68 it is determined whether or not a predetermined period t8 has elapsed in the case of a shift down. If the determination result is false (No), the process waits for a predetermined period t8 to elapse. On the other hand, when the result of the determination is true (Y es), the process proceeds to step S70.
- step S70 the gearshift is completed, and the gearshift is carried out without any problem, so that the warning lamp 83 is kept off.
- step S72 in response to the completion of the gear shift, an instruction to return the engine torque Te changed in step S10 is issued, and the engine control is returned to the normal control state and the engine is returned to the normal control state. Restore the torque Te.
- step S68 it is determined whether or not the predetermined period 8 has elapsed in step S68, and after the determination result is true (Y es) and the predetermined period t8 has elapsed, step S68 is performed. After step S70, an instruction to return the engine torque Te is issued in step S72. As a result, a sudden change in the engine torque Te is suppressed, and the gear is prevented from coming off.
- the process proceeds to step S72 without waiting for the predetermined period t8 to elapse, and the return instruction of the engine torque Te is immediately issued.
- FIG. 6 a control routine of clutchless shift control according to a second embodiment of the present invention is shown by a flowchart, and the second embodiment will be described below based on the flowchart. I do.
- the same steps as those in the first embodiment are denoted by the same step numbers, and the description thereof will be omitted. I will explain only.
- step S12 ' it is determined whether or not a predetermined period to has elapsed after changing the engine torque Te based on the speed change command. That is, when the engine torque Te is obtained, and the control rack is controlled to change the fuel injection amount so that the engine torque Te is obtained, the clutch torque Tel becomes 0 (zero) after a predetermined period t0 has elapsed. Or it can be considered that it has become near. Therefore, if the result of the determination is true (Yes) and it is determined that the predetermined period to has elapsed, the process proceeds to step S16 to instruct gear removal. Also in this case, the gear should be easily disengaged without a shock without operating the clutch device 3. On the other hand, if the determination result of step S12 ′ is false (No) and it is determined that the predetermined period tO has not elapsed, the process waits for the predetermined period tO to elapse.
- step S26 simple F-NOB control is performed instead of the Ne-F NO-B control in FIG.
- the auxiliary brake is turned on in step S26, and in step S27, the engine rotational speed Ne is set at a predetermined value N3 from the target Ne in the gear position after shifting. It is determined whether the rotation speed is within the range of high rotation speed (Ne ⁇ target Ne + N3). If the determination result is false (No), it can be determined that the engine rotation speed Ne is too high. In this case, the process returns to step S26 'via step S29', and continues to turn on the auxiliary brake. That is, the exhaust brake 52 is closed and the engine speed Ne is continuously reduced.
- step S27 'or step S29' determines whether the engine speed Ne falls within the range of the rotation speed that is higher than the target Ne in the gear position after the shift by a predetermined value N3. Then, it is determined that the engine speed Ne is substantially synchronized with the target Ne in the gear position after the shift, the auxiliary brake is turned off, and the process proceeds to step S30 and subsequent steps in FIG.
- the clutch device 3 The engine torque Te is calculated from the above equation (5) so that the latch torque Tel is at or near the value 0 (zero), and the gear is disengaged without operating the clutch device 3 under the engine torque Te. I have to. Therefore, the shift time can be shortened and the shift can be promptly achieved without occurrence of a shock due to gear disengagement.
- the gear is engaged while the engine rotational speed Ne is substantially synchronized with the target Ne in the gear after the shift, so that the clutch device 3 can be connected and disconnected without operation.
- the gear can be smoothly shifted.
- the clutchless shift control is performed in response to a shift command in the automatic shift mode.
- the present invention is not limited to this.
- the clutch shift control is output in response to a shift operation by the driver.
- Clutchless shift control may be performed in response to a shift command. In this case, when the driver performs the clutch pedal operation, the clutch operation may be disengaged by giving priority to this pedal operation.
- a diesel engine is used as the engine type, and a configuration in which the fuel injection amount is controlled by the injection pump 6 as the control means of the engine torque Te and the engine rotation speed Ne is adopted.
