- step S98 determines whether the moving amount of the first and second shutters 31 and 32 exceeds the predetermined moving amount A1.
- step S99 it is determined in step S99 whether the predetermined time T1 has elapsed.
- the process returns to the process of step S97. If it is determined in step S97 that the stop condition is satisfied, the CPU 41 stops the opening operation of the first and second shutters 31 and 32 in step S100.
- step S98 When it is determined in step S98 that the moving amount of the first and second shutters 31 and 32 exceeds the predetermined moving amount A1, the CPU 41 stops the opening operation of the first and second shutters 31 and 32 in step S101.
- step S99 when it is determined in step S99 that the predetermined time T1 has elapsed, the CPU 41 stops the opening operation of the first and second shutters 31 and 32 in step S101. That is, when the CPU 41 determines that the stop condition is not satisfied in step S97, the CPU 41 continues until the movement amount of the first and second shutters 31 and 32 exceeds the predetermined movement amount A1, or the predetermined time T1 The opening operation of the first and second shutters 31 and 32 is continued until it elapses.
- step S102 When the opening operation of the first and second shutters 31 and 32 is stopped in step S100, it is determined in step S102 whether the movement amount of the first and second shutters 31 and 32 is normal. Then, when it is determined that the movement amount of the first and second shutters 31 and 32 is not normal, the CPU 41 determines that some abnormality satisfying the stop condition has occurred (abnormality detection unit), step S103. Move to and make an abnormality judgment. In addition, when the opening operation of the first and second shutters 31 and 32 is stopped in step S101, the CPU 41 determines that some abnormality for which the stop condition is not satisfied has occurred (abnormality detection unit), step S103. Move to and make an abnormality judgment. The CPU 41 increments the abnormality determination counter CNT1 when an abnormality determination is made.
- the abnormality determination counter CNT1 at the current stage of the current routine is a value obtained by counting only the number of abnormality determinations associated with the opening operation of the first and second shutters 31 and 32. This is because, particularly when abnormality detection is performed based on the movement amounts of the first and second shutters 31, 32, it is basically necessary to perform only one of the opening operation and the closing operation.
- step S104 it is determined whether the number of abnormality determinations is equal to or greater than a predetermined number.
- a predetermined number abnormality determination unit
- caution display is performed in step S105, and the operation of the first and second shutters 31 and 32 is prohibited (prohibition unit ).
- step S102 When it is determined in step S102 that the movement amounts of the first and second shutters 31 and 32 are normal, the CPU 41 determines normality in step S106. Then, the CPU 41 clears the abnormality determination counter CNT1 to zero in step S107, shifts to step S61 in FIG. 6, and shifts to the above-described normal control. Alternatively, if it is determined in step S104 that the number of abnormality determinations is less than the predetermined number, the CPU 41 shifts the process to step S61 of FIG. 6 to perform normal control.
- the first and second shutters 31 and 32 are not activated due to the establishment of the operating condition in the normal control (YES in step S61 or S62), the first and second shutters 31 and 32 are not An opportunity for anomaly detection is obtained.
- the first and second shutters 31 and 32 return to normal until the current ignition switch 43 is turned on (that is, the ignition switch 43 is turned off) (NO in step S104), the caution display is not performed, The operation prohibiting state of the first and second shutters 31 and 32 is released (release unit).
- the above-described routine is executed while the ignition switch 43 is in the on state, and ends when the ignition switch 43 is switched off, unless the caution display is performed.
- the CPU 41 stores and holds the history indicating the execution of the caution display in the memory 41a in a battery backed up state. .
- step S98 or S99 or NO in step S102 Since the abnormality detection (YES in step S98 or S99 or NO in step S102) is performed only by the opening operation of the first and second shutters 31 and 32, the process can be simplified.
- the retry at the time of abnormality detection (YES in step S5 or S16, or NO in step S8 or S19) may be omitted or may be performed three or more times.
- it may be made to wait for a fixed time.
- the retry at the time of abnormality detection may be omitted or may be performed three or more times.
- it may be made to wait for a fixed time.
- the abnormality detection prior to the normal control may be performed only in one of the opening operation and the closing operation of the first and second shutters 31 and 32.
- a plurality of retries may be performed. In this case, retry may be performed after waiting for a fixed time.
- a plurality of retries may be performed. In this case, retry may be performed after waiting for a fixed time.
- the abnormality detection prior to the normal control may be performed in the closing operation instead of or in addition to the opening operation of the first and second shutters 31 and 32.
- the determination of the fully open position or the fully closed position may be performed by, for example, an on / off signal of a limit switch.
- the caution display mode when the ignition switch 43 is turned off in the caution display mode and the operation of the first and second shutters 31 and 32 are inhibited, the caution display mode may be temporarily canceled. Then, the first and second shutters 31 and 32 may be forcibly operated according to the switching on of the next ignition switch 43 (third operating unit). In this case, it is possible to obtain an opportunity to detect an abnormality associated with the operation of the first and second shutters 31 and 32, in conjunction with the switching on of the next ignition switch 43. At this time, when the abnormality is not detected, the CPU 41 cancels the caution display and the operation prohibiting state of the first and second shutters 31 and 32 to restore the normal state. On the other hand, when the abnormality is detected, the caution display and the operation inhibition of the first and second shutters 31 and 32 are immediately performed.
- the first and second shutters 31 and 32 do not reach the predetermined time (first predetermined time) after the start of operation of the first and second shutters 31 and 32 when the corresponding stop condition is satisfied.
- An abnormality of the second shutters 31 and 32 may be detected. This is because, for example, when the load increases due to the fixation of the first and second shutters 31 and 32 and the pinching of the foreign matter, the stop condition is established earlier than originally. Therefore, the elapsed time after the start of the operation of the first and second shutters 31 and 32 is monitored, and an abnormality can be detected when the stop condition is satisfied without the elapsed time reaching the predetermined time.
- notification to the user may be performed each time an abnormality is detected or each time an abnormality is determined after a retry.
- the determination of the stop condition may be performed using an appropriate physical quantity correlated with the driving force of the first and second drive devices 37 and 38.
- the subsequent operation of the first and second shutters 31 and 32 may not necessarily be prohibited in the caution display.
- notification to the user at the time of abnormality detection may be performed by, for example, a speaker or a buzzer as a notification unit.
- the first and second drive devices 37 and 38 may be configured as a single drive device, and the first and second shutters 31 and 32 may be opened and closed together.
- the warm-up performance of the engine 2 can be improved by moving the first and second shutters 31 and 32 to the fully closed position, for example, when the outside air temperature is low as the closing operation start condition. it can.
- the cooling performance can be improved by moving the first and second shutters 31 and 32 to the fully open position.
- the heating performance is improved by moving the first and second shutters 31 and 32 to the fully closed position. It can be improved.
- the cooling performance can be improved by moving the first and second shutters 31 and 32 to the fully open position when the cooling state or the refrigerant pressure in that state is high as the open operation start condition.
- the air resistance (air resistance coefficient) and the lift are reduced by moving the first and second shutters 31 and 32 to the fully closed position, for example, when the vehicle speed is high as the closing operation start condition.
- the downward flow of the air on the front side of the vehicle can generate a downforce that pulls the vehicle downward. And the stable traveling state of the vehicle can be secured.
- the opening and closing of the first and second shutters 31 and 32 based on the vehicle information may be adjusted to an arbitrary opening and closing position between the fully closed position and the fully open position.
- the first and second drive devices 37 and 38 may be configured as a single drive device, and only one of the first and second shutters 31 and 32 may be opened and closed. That is, any one of the first and second shutters 31 and 32 may be fixed in an open state, for example. In this case, it is more preferable to fix the second shutter 32 in the open state.
- first and second shutters 31 and 32 may be opened and closed by, for example, slide movement.
