In addition, the output current output from the signal processing means 44 to the electronic control device 50 side is kept constant at 7 mA (low state) as shown in FIG. 7B, and the brake pedal 5 operates. As long as the piston 4 is stopped, the output current is maintained at 7 mA.

When the vehicle user steps on the brake pedal 5 and the brake pedal 5 is operated, the piston 4 is positioned on the magnetic field path as shown in FIG. 8, and the magnetic field passing through the master cylinder 3 is a piston. You will go through (4).

When passing through a magnetic body (piston 4 comprising a metal material) than when passing through only a liquid such as air or oil, the magnetic field strength becomes larger.

In particular, when the edge (edge) of the piston 4 is located on the magnetic field path flowing into the magnetic sensing means 43 side, as shown in Fig. 9 (a), the change amount ΔB of the magnetic flux density increases rapidly (maximum) )

When the amount of change in the magnetic flux density increases rapidly, the signal processing means 44 changes the output current to 14 mA (high state) and outputs the signal as shown in FIG.

When the vehicle user releases the brake pedal 5 and the piston 4 is again positioned as shown in Fig. 6, the output current of the signal processing means 44 is changed back to 7 mA (low state).

It has a circuit structure that can receive and control the lighting of the brake light (9).

The electronic controller 50 is connected to the terminal 45 of the brake light sensor 40 connected to the input wire 47 and the output wire 48.
