Definitions
- the rear wheel side disc brake 6 propels the piston 6D by the brake fluid pressure generated based on the operation of the brake pedal 9, etc., and presses the disc rotor 4 with the brake pad 6C, thereby extending the wheel (rear wheel 3). provides braking force to the vehicle.
- the rear wheel side disc brake 6 is driven by the electric motor 7A via the rotation/linear motion conversion mechanism 8 in response to an operation request based on a signal from the parking brake switch 23 or the like. It propels the vehicle and applies the braking force (parking brake, if necessary auxiliary braking while driving) to the vehicle.
- An apply request signal serving as a signal and a release request signal serving as a release request signal) are output to the braking control device 17 .
- a signal such as accelerator pedal operation information, which is input via the vehicle data bus 20 serving as a communication line, may be used.
- the braking control device 17 includes an arithmetic circuit 24 for controlling the hydraulic pressure supply to the ESC 16 and applying and releasing the electric parking brake, an ESC drive circuit 27 for controlling the electric motor 16A of the ESC 16, etc. Motor drive circuits 28, 28 for controlling the electric motors 7A, 7A of the electric parking brake are incorporated.
- FIG. 4 shows the overall control configuration of the embodiment.
- the control configuration is composed of five control blocks (inrush current detection unit 32, vehicle stop determination unit 33, pedal depression presence/absence detection unit 34, apply completion determination unit 35, motor drive signal calculation unit 36). Although illustration is omitted, the same control is performed on the left and right. However, if the left and right electric motors 7A, 7A are driven at the same time, the electrical load increases, so it is preferable to drive the electric motors 7A, 7A with different timings on the left and right sides.
- FIG. 6 shows the vehicle stop determination process performed by the vehicle stop determination unit 33 .
- the processing shown in FIG. 6 is repeatedly executed at a predetermined control period (for example, 10 ms).
- S11 it is determined whether or not the wheel speeds of all the four wheels are invalid values.
- the invalid value corresponds to, for example, a value deviating from a normal value, a value when the wheel speed cannot be obtained normally due to a failure of the wheel speed sensor, or the like. If “NO” in S11, that is, if it is determined that at least one of the wheel speeds of the four wheels is invalid, the process proceeds to S12.
- the stop determination flag is set to "OFF". "OFF" corresponds to "the vehicle is not stopped (running)". If the stop determination flag is set to "OFF” in S12, the process proceeds to the end.
- the current threshold for completing the application is reduced based on the WC pressure, and the completion of application is determined based on this reduced current threshold.
- the braking force that can maintain the vehicle stopped considering the road gradient is applied. It is determined that the application is completed when a current threshold value that can be generated is reached.
