Definitions
- the present invention relates to an electric brake device that generates a braking force by the operation of an electric motor.
- a braking device that generates braking force by the operation of a motor without using hydraulic means is mounted on multiple wheels of a vehicle, it is necessary to individually control the braking force of each wheel. Therefore, if the accuracy of the braking force control is not sufficient, there is a possibility that a braking force difference may be generated in each wheel, which makes the vehicle behavior unstable. For example, when a braking force difference is generated between the left and right wheels of a car, a single angular velocity is generated in the vehicle body during braking, which gives a discomfort to the occupant. In addition, the body will spin at the first ⁇ 3 ⁇ 4 ⁇ exit.

If a high-resolution thrust sensor is used, high-precision control of the Boston thrust is theoretically possible. However, the electric brake is subject to vibrations caused by unevenness on the ground, so when equipped with a thrust sensor, not only reliability is reduced, but if a thrust sensor with high resolution is used, Since the resolution of the AD converter must be increased, it is disadvantageous in terms of cost. Furthermore, the temperature of the electric brake is determined by the ambient temperature and the temperature of the brake pad, and is not constant. Therefore, in the case of a strain gauge type thrust sensor, the sensor temperature And the control mechanism becomes complicated.

- the rotation-linear motion conversion mechanism 15 is driven by the rotation torque expanded by the reduction gear 14, and the piston 16 moves forward.
- the brake node 17 attached to the piston 16 moves forward with the piston 16 and presses the tissue clock 18. Since the carrier 21 is supported for floating, the disk drive 18 is sandwiched between two blades, providing a stable braking force. You can get it.
- the method of controlling the force (piston thrust) that presses the disk mouth 18 is generally based on (1) the motor torque obtained from the motor current value. (2) Estimating the Boston thrust from the Boston position obtained from the motor rotation angle (Motor position) and the rigidity of the entire capper There is a possible method.
- the motor current value does not match when the thrust is increased and the power is opened. This is a phenomenon that occurs because the power transmission efficiency of the power transmission system such as the reduction gear 14 and the rotary / linear motion conversion mechanism 15 is not 100% .
- the transmission efficiency depends on the temperature and the lubrication state of the sliding parts. Change. Therefore, it is practically impossible to control the piston thrust by the method (1).
- the piston thrust is controlled based on the rotation angle of the motor, so the motor angle corresponding to the contact position between the brake pad and the disk opening is detected with high accuracy.
- the motor angle corresponding to the contact position between the brake pad and the disk opening is detected with high accuracy.
- This embodiment is basically an electric brake in which the thrust is controlled by the method (2).
- the key feature is that the difference in braking force between the left and right wheels of the vehicle is reduced without the need to detect a high-m contact position between the brake node and the disk mouth.
- FIG. Fig. 4 (a) shows the standby position of the left and right wheel brake pads 17 during non-braking.

- the braking force of the electric brake to which the present invention is applied is usually
- Step -1 is controlled by controlling the evening position (Step 1).
- Step 2 If it is determined that the vehicle is stopped (Step 2), the braking force of the front wheels must be reduced in order to ensure safety during the operation of the rear wheel brakes described below. Fix to the braking force F that can keep the vehicle stationary (Step 3). Next, the motors of the left and right electric brakes are returned to the reference position corresponding to the brake pad standby position during non-braking (Step 4), and the motors of the left and right electric brakes are sufficiently turned off. Rotate by the specified angle ⁇ to generate braking force, and generate braking power (Step 5).

- the absolute value of ⁇ ⁇ is compared with the specified value ⁇ (step 7) If it is smaller than ⁇ , return to the normal state without performing the operation to reduce the thrust difference between the left and right wheels (in the case of No judgment in Step 7). Note that ⁇ is determined based on the difference in braking force between the left and right wheels that makes the vehicle unstable, and that ⁇ I is smaller than £ means that the thrust of the left and right wheels is enough to make the vehicle unstable. A difference means that there is no difference. If the absolute value of ⁇ is larger than ⁇ (Yes in Step 7), calculate the magnitude of the motor current value of the left and right electric brakes (Step 8).
- the current flowing through the motor of the left and right wheel electric brakes may be combined with the current having a larger current value and a larger current value.
- the amount of current to be changed may be arbitrarily determined based on ⁇ I.

- Step 13 It is not necessary for the left and right electric brakes in Step 13 to have the same rotation angle when the motors are rotated in the opposite direction to the rotation direction of the motors and motors in Step 5. ⁇ For example, you may decide as follows.
- the number of operation repetitions from 5 to step 14 can be reduced, and effects such as reduction in power consumption can be obtained.
- Step 1 when the driver measures the pedaling force applied to the brake pedal 10 and detects that the pedaling force has fallen below the threshold value Fs. Immediately move to Step 1 to return the vehicle to a state where it can be started.
- a brake vibration called "jada” may occur. This phenomenon is based on the fact that rust occurs on the disk and thermal distortion occurs, resulting in an uneven thickness of the disk mouth. 'Cause. If the above steps 4 to 14 are performed with the disk brake where the judder has been generated, the disk may be moved to a place where the thickness of the disk opening is different. When the rake pad is pressed, the effect of correcting the thrust difference between the left and right wheels may not be obtained. In order to deal with this, Perform the operations from Swap 1 to Step 14 when the vehicle stops in the past, and memorize the reference positions of the determined models, and perform the statistical operations on them. And good. For example, the non-uniformity of the disk thickness was obtained by averaging the brake reference positions obtained by thrust difference calibration performed during the last five vehicle stops. Therefore, it is possible to reduce the effect of the above.
- step 5 the motors of the left and right wheel electric brakes were rotated by the specified angle 0 so that sufficient braking force was obtained, but the value of 6> was reduced to a small value.
- a current larger than the current flowing through the electric brake motor of the right wheel is simulated, and the steps from step 1 shown in Fig. 5 are repeated.
- the motor current of the right-wheel electric brake is equal to the motor current of the left wheel so that the difference in braking force between the left and right wheels becomes smaller in the operation of o, which performs the operations up to 14. To increase.
- the electric current of the left wheel is also changed. It can be confirmed that the current of the rake motor increases overnight.
