This invention discloses a dual electromechanical braking device and its control method for automotive braking. The braking device includes a
drive motor, an external gear ring, a reduction and torque amplification device, an
electromagnetic power supply, an
electromagnet A, a permanent
magnet A, a first braking execution module, a second braking execution module, a first clamping mechanism, a second clamping mechanism, a first friction pad, a second friction pad, a
brake disc, a bearing, a parking device, a displacement detection device, and a
brake wear detection device. This invention uses two sets of braking devices to apply double braking to the
brake disc, resulting in shorter braking time, better braking effect, and effectively improved safety performance. This invention also provides a control method for the braking process, including control methods for
normal mode, emergency braking mode, and parking mode. During braking, if the braking device fails due to power failure, the detection device will promptly issue a safety alarm to the driver and immediately activate the other braking device for emergency braking, achieving
backup braking.
