Embodiment Construction

[0018] Such as figure 1 As shown, each wheel is equipped with an electric brake and a wheel speed sensor. Such as Figure 4 As shown, the electric brake includes a brake caliper body 1, a motor 7, and also includes a lead screw 3 and a lead screw nut 2. The motor can drive the lead screw nut 2 to rotate through the reduction mechanism 5, and the lead screw nut drives the lead screw to perform a feed movement. brake. The end of the output shaft of the motor is provided with a power-off brake 6 . The outer end of the leading screw is provided with a butterfly spring 4.

[0019] During the braking operation, the power-off brake 6 is energized, and the motor 7 rotates forward to output torque. After the torque is decelerated by the deceleration mechanism 5 and the torque is increased, the torque is transmitted to the lead screw nut 2, and the lead screw nut 2 rotates to drive the feed movement of the lead screw 3. . At the same time, when the de-energized brake 6 is energized...

Abstract

The invention relates to a brake control method of an automobile brake-by-wire system and an electric brake. The brake mode comprises a travelling braking mode and a parking braking mode; in the travelling braking mode, an electronic brake pedal sends a travelling braking signal to a control unit, and the control unit drives the electric brake to realize travelling brake through a driving unit according to the travelling braking signal; and in the parking braking mode, a parking button sends a parking braking signal to the control unit, and the control unit drives the electric brake to realize parking brake through the driving unit according to the parking braking signal.

Description

technical field [0001] The invention relates to a braking control method and an electric brake of an automobile wire-controlled braking system. Background technique [0002] At present, most vehicle braking systems at home and abroad are still based on hydraulic energy transfer systems to achieve vehicle braking. However, the traditional hydraulic brake has defects such as complex structure, inconvenient installation, high price, failure to be monitored in real time, and slow brake response. The disadvantages of the existing few automobiles that adopt the brake-by-wire system are: inconvenient use, poor braking accuracy, and the structure of the electric brake is relatively complicated. Contents of the invention [0003] The object of the present invention is to provide a brake control method and an electric brake of an automobile brake-by-wire system, which are reliable in operation and easy to use. [0004] The present invention is based on the same inventive concept a...
