Additionally, according to Utility Model Application Publication No. 54-105429@, power is supplied to the motor that operates the sight brake through the respective operations of a foot brake switch that responds to the foot brake depression and a push button switch that operates when the site brake is commanded to operate. However, an idea related to a "site brake control device" is disclosed, which is characterized in that the power supply to the motor is stopped in response to the depression of the accelerator pedal or the clutch pedal. Further, according to JP-A-55-140634, parking brake operation detection means detects that the parking brake is applied, and accelerator pedal operation detection means detects that the accelerator pedal is depressed. [Automobile parking brake automatic release device] characterized by comprising a shift 1 position detection means for detecting the shift position of the transmission, and a release means for releasing the parking brake based on signals from each of these means. ” is disclosed.

。First, according to steps 81 to S6 in FIG.
Check the condition of the vehicle based on G. Then, fK1 confirms that there is no defect in the main brake system by each of the above signals CG, and the conditions for controlling the parking brake are in place, that is, the vehicle speed is less than or equal to the set vehicle speed V, and the deceleration rate is It is normal and the ignition switch is turned on.
If it is confirmed that the engine is running and that the forward or reverse direction of the vehicle matches the gear position, the parking brake is controlled by the manual switch 22 according to steps 87 to Sto. It will be done. That is, when the manual switch 22 is operated to the operating position, a brake operation command signal A' is output to the motor 6, and when the switch 22 is operated to the release position, a brake release command signal B' is output. . As a result, the parking brake is activated or released by manual switch operation. In this case, if the signal C from the brake fluid level sensor 12 indicates that there is a defect in the main brake system, step S1 is performed regardless of whether the above conditions for parking brake control are met. Then, according to steps 87 to S+o, the parking brake can be controlled by the manual switch 22. In addition, if there is no defect in the main brake system, if the vehicle speed is higher than the set vehicle speed V or if the deceleration rate is abnormal, the parking brake will not be controlled (steps S2' and S3), and the ignition switch will not be turned OFF. When the engine is stopped and the direction of travel of the vehicle does not match the gear position of the transmission, the parking brake is activated regardless of the state of the manual switch 22 (sleeves S4, Ss, 86.S8). )

It? signal from sensor 13, accelerator sensor 17 and main brake sensor 18, H, I
Check whether the operating conditions for the parking brake are met based on the following. When these conditions are met, that is, when it is confirmed that the vehicle speed is O, the accelerator pedal is released, and the brake pedal is depressed, the controller 11 sends a brake operation command signal A to the motor 6.
is output. As a result, the motor 6 rotates in the brake activation direction until a signal is output from the stop timing detection sensor 23, and the parking brake is activated.

てから駐車ブレーキが解除されることになる。。After the parking brake is activated in this way, when the accelerator pedal is depressed to start the car, and a signal 1 from the accelerator sensor 17 indicating this is input to the controller 11, the controller 11 moves from step S14 to step 817. -822 is controlled. That is, when the accelerator pedal is depressed, it is confirmed that the transmission is in the driving position by the signal G from the position sensor 16, and then the gradient of the road surface is detected by the signal G from the slope sensor 19. According to the characteristics shown in FIG. 3 stored in the controller 11, the required engine rotation speed at the time of releasing the parking brake is set in accordance with the detected gradient (steps 817 to 519). Then, an increase in engine speed due to depression of the accelerator pedal is detected by the signal K from the engine speed sensor 20, and this measured engine speed is compared with the set engine speed, and the actual rotation speed is determined to be the set speed. When the brake pedal exceeds the limit, it is further confirmed that the brake pedal has been released by the signal I from the main brake sensor 18, and then the motor 6 starts operating in the brake release direction (step S20-822). As a result, when starting on an uphill road, the parking brake is released after the engine output increases by -L to an output corresponding to the road surface gradient. .

An accelerator pedal depression amount sensor that indirectly detects the engine speed based on the amount of depression of the accelerator pedal may be used. In this case, the accelerator pedal depression amount sensor can also be used as the accelerator sensor 17 in the above embodiment, which detects whether or not the accelerator pedal is depressed.

There is a risk that the parking brake will be released early due to the increase in engine speed. For this, the third
As shown by the dotted line in the figure, the engine speed required for releasing the parking brake may be controlled to shift toward a higher engine speed depending on the road surface slope when the idle up signal is input.

問題が解消され、常に良好な発進動作が得られる。As described above, according to the present invention, in the electric parking brake device that automatically controls the activation and release of the parking brake, when starting on an uphill road, the parking brake is activated after the engine output increases to an output corresponding to the road surface gradient. It will be canceled. This eliminates the problem of the parking brake being released and the vehicle moving backwards even though the engine output is not sufficient on a steep uphill road, and a good starting operation can always be obtained.
