The invention relates to the technical field of
vehicle brake control systems, and particularly provides a distributed type autonomous
braking system with a parking function and a control method. Thesystem comprises a power supply, a
brake controller and wheel brakes, and further comprises at least three electric cylinders which are connected with the wheel brakes and form
brake loops; each electric cylinder comprises an electric cylinder body, a
piston arranged in the electric cylinder body in a sliding manner, a motor for driving the
piston to slide by a screw pair arranged in the electriccylinder body and a
liquid storage pot connected with the electric cylinder body; the motors are electrically connected with the
brake controller; each screw pair comprises a nut driven by the corresponding motor and a screw connected with the corresponding
piston; and the electric cylinders are connected to the wheel brakes with the same number on an automobile in a one-to-one correspondence manner, and each electric cylinder and the corresponding wheel brake form one brake loop. Compared with the prior art, the
system has a failure protection function, higher safety performance, the parkingfunction, simple structure and lower cost.
