Abstract

PURPOSE:To obtain smooth starting of a car on an upward slope by delaying a speed of releasing action of a parking brake of an electromagnetic device by a detection signal of the inclination of a road face. CONSTITUTION:One end of a cable 5 for parking brake is connected with brakes 3 provided at rear wheels 2, while the other end is connected with a wind-up member 10, which is driven for rotation by a motor 6 via gear mechanisms 7-9. The driving of the motor 6 is controlled by a controller 11, to which signals from various sensors such as a speed, an accelerator, a gear position, a brake and an inclination sensor are supplied to operate the parking brake automatically when a car is stopped and release the parking brake automatically when the car is started. When the car is parked on an upward slope, the motor 6 is controlled to delay the releasing action of the parking brake as the inclination becomes stepper.

。First, according to steps 81 to S6 in FIG.
The roller 11 receives signals C~ from a brake fluid level sensor 12, a vehicle speed sensor 13, an ignition switch 14, a regulator voltage sensor 15, and a position sensor 16.
The condition of the vehicle is confirmed based on G. Then, it is confirmed by each of the above signals CG that there is no defect in the main brake system, and that 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,
If it is confirmed that the deceleration rate is normal, the ignition switch is ON, the engine is running, and the direction of travel of the vehicle (forward or reverse) matches the gear position, then steps Sγ to S 1o, the parking brake is controlled by the manual switch 22. 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, brake fluid level sensor 1
If the signal C from 2 indicates that there is a defect in the main brake system, the manual switch is activated according to steps S1 to Sγ to S10, regardless of whether the above conditions for parking brake control are met or not. 22, the parking brake can be controlled. 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 82 and 83), and - when the ignition switch is OFF, 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. is activated (steps Sa, Ss, S6.Sa)

Ａが出力される。First, after confirming that the automatic control prohibition signal, which is output when automatic control is not desirable based on the driving condition of the vehicle, is not being output, and that the switch to switch to automatic control is turned on, Signals from the vehicle speed sensor 13, accelerator sensor 17 and main brake sensor 18, H,
Based on I, it is confirmed whether the operating conditions for the parking brake are satisfied. 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.

Control is performed according to the rib flow shown in FIG. That is,
The slope of the road surface is detected by the signal J from the slope sensor 19, and the release speed of the parking brake is set in accordance with the detected slope according to the characteristics stored in the controller 11 as shown in FIG. Then, the motor speed regulator 21 is controlled to achieve the set speed, and the motor 6 is driven in the brake release direction at the set speed.Steps S25, S26, S27
>. After that, if the parking brake is completely released, the motor 6 is stopped (steps 328, 529). As a result, the speed at which the car brake is released can be appropriately controlled depending on the road surface slope, and for example, when starting on a steep road, the parking brake may be released too quickly and the car may move backwards. The problem will be resolved.
