Electro-hydraulic hybrid braking system for vehicle

An electro-hydraulic hybrid braking system for a vehicle, comprising a plurality of wheel-end braking modules, a hydraulic control module, a first electronic control module, and a second electronic control module, wherein each of the plurality of wheel-end braking modules comprises a hydraulic piston, a motor, and a speed-reducing transmission mechanism configured to convert a rotary motion from the motor into a linear motion for driving the hydraulic piston or brake friction plates to move forwards, wherein the hydraulic piston is movably arranged and is movable forwards through brake hydraulic pressure, and the motor of is controlled by the first electronic control module and/or the second electronic control module;

• wherein speed-reducing transmission mechanisms of at least two of the plurality of wheel-end braking modules have a self-locking function, and speed-reducing transmission mechanisms of the other wheel-end braking modules of the plurality of wheel-end braking modules do not have the self-locking function;
• wherein the speed-reducing transmission mechanisms with the self-locking function are disposed at left and right ends of a front axle or a rear axle of the vehicle, after a driving voltage of the motor of the corresponding wheel-end braking module is removed, the brake friction plates maintain elastic deformation and a braking force remains;
• and after a driving voltage of the motor of the wheel-end braking module in which each of the speed-reducing transmission mechanisms without the self-locking function is located is removed, the brake friction plates are restored from the elastic deformation and the braking force decreases.
