5 is a flowchart showing a control method of a manual / automatic bite removal apparatus for a side mirror according to the present invention.

In step 21, a signal input from the mode selection switch unit 6 is checked to determine whether the manual mode is input. If the manual mode is input, the process proceeds to step 32 where the side mirror 9 is operated manually. If the manual mode is not input, the automatic mode is operated. In step 22, it is determined whether the water buried in the side mirror 9 is less than the prescribed value. If it is less than the regulation, the process of step 21 is repeated, and if it is not less than the regulation, it is determined in step 23 whether the speed of the vehicle is greater than or equal to the prescribed speed Vr. If the speed is equal to or greater than the prescribed speed Vr, it is determined in step 24 whether the water buried in the side mirror 9 is the fourth set amount (area of IV in Fig. 4). In the case of the fourth set amount, the oscillation unit 18 is controlled in step 25 to drive the vibrating element 11 under vibration condition 4 to generate a pulse with the waveform of pulse 4 among the vibration pulses shown in FIG. After driving the heating wire 10, the process of step 21 is repeated.

After driving the heating wire 10, the process of step 21 is repeated.

If the speed of the vehicle is not greater than the prescribed speed Vr in the judgment of step 23, it is determined whether the water buried in the side mirror 9 in step 27 is the first set amount (area of I in FIG. 4).

After driving the heating wire 10, the process of step 21 is repeated. If it is not the first set amount, it is determined in step 29 whether the water buried in the side mirror 9 is the second set amount (region II in FIG. 4).

In the case of the second set amount, the oscillation unit 18 is controlled in step 30 to drive the vibration element 11 under vibration condition 2 which generates a pulse with the waveform of pulse 2 among the vibration pulses shown in FIG. After driving the heating wire 10, the process of step 21 is repeated.

If it is not the second set amount, the oscillation unit 18 is controlled in step 31 to drive the vibrating element 11 under the vibration condition 3 which generates a pulse with the waveform of pulse 3 among the vibration pulses shown in FIG. After driving the heating wire 10, the process of step 21 is repeated.

When the driver selects the manual mode by pressing the manual switch of the mode selection switch unit 6, a signal of pulse 3 is input to the control unit 8, and the control unit 8 receives the manual mode selection signal and then returns to FIG. The oscillation element vibrates while the oscillation element is outputted to the oscillator 18 by outputting a signal such as the illustrated pulse 2 to the oscillator 18.
