- FIG. 4 is a flowchart showing a continuation of the control process of FIG. 3.
- the stroke sensor 4 detects the amount of brake pedal operation (depression) by the driver.
- the stroke sensor 4 is connected to the control device 18 via a signal line 4A.
- the detection signal of the stroke sensor 4 is output to the control device 18 as a braking request signal of the present invention.

- the starter motor 16 is an electric motor that operates when starting the engine. That is, the starter motor 16 operates when the driver turns on an engine start switch (ignition switch) or an engine restart switch (idle switch) (not shown).
- the starter motor 16 is connected to the main power supply 5 via the power supply line 6 and is supplied with power from the main power supply 5.
- the control device 18 receives the detection value of the stroke sensor 4 based on the operation of the brake pedal by the driver. Then, the control device 18 operates the electric motor 3 based on the detection signal (braking request signal) of the stroke sensor 4 to generate brake fluid pressure in the master cylinder 2.
- the control device 18 is electrically connected to the starter motor 16 via the signal line 17 and receives a start detection signal from the starter motor 16 to detect whether the starter motor 16 is operating. .
- the control device 18 is provided with a power supply control unit 19.
- the power supply control unit 19 controls the ON state (connected state) or OFF state (non-connected state) of the first switch element 14 and the second switch element 15 to supply power to the motor 3 from the main power supply 5. Or the auxiliary power supply 10 is controlled.
- the memory (not shown) of the power supply control unit 19 stores the control processing program shown in FIGS. 3 and 4 and the voltage thresholds (Va, Vb) of the main power supply 5.
- the power supply control unit 19 performs the switching operation of the first switch element 14 and the second switch element 15 according to the control processing program shown in FIGS. 3 and 4.
- the brake device according to the present embodiment has the above-described configuration, and the operation thereof will be described next.

- step 1 is indicated as “S1”.
- S9 it is determined whether or not the drive of the starter motor 16 is finished. That is, if “YES” is determined in S3 in FIG. 3, it is determined whether or not the start of the engine is completed and the starter motor 16 has been driven. If “YES” in S9, that is, if it is determined that the drive of the starter motor 16 has been completed, the process proceeds to S10. On the other hand, if “NO” in S9, that is, if it is determined that the drive of the starter motor 16 has not ended, the process proceeds to S11.
