Brake-by-wire system based on dual-motor configuration and operation methods thereof

A brake control system of a vehicle comprising:

• a first electric motor, a second electric motor, a first piston cylinder comprising a first hydraulic chamber and a first piston, where the position of the first piston defines the volume of the first hydraulic chamber, a second piston cylinder comprising a second hydraulic chamber and a second piston, where the position of the second piston defines the volume of the second hydraulic chamber, a plurality of wheel cylinders, and a hydraulic control unit (HCU) comprising a first set of electromagnetic valves and a second set of electromagnetic valves;
• wherein
• the first electric motor is mechanically connected to the first piston of the first piston cylinder via a first motion converter that converts rotational motion of the first electric motor to linear motion of the first piston, and the second electric motor is mechanically connected to the second piston of the second piston cylinder via a second motion converter that converts rotational motion of the second electric motor to linear motion of the second piston;
• all electromagnetic valves in the first set of electromagnetic valves are hydraulically connected in fluid communication with each other, and all electromagnetic valves in the second set of electromagnetic valves are hydraulically connected in fluid communication with each other;
• the first hydraulic chamber is hydraulically connected with each of the first set of the electromagnetic valves, and the second hydraulic chamber is hydraulically connected with each of the second set of the electromagnetic valves;
• and
• each of the first set of the electromagnetic valves is hydraulically connected with one and only one corresponding wheel cylinder, each of the second set of the electromagnetic valves is hydraulically connected with one and only one corresponding wheel cylinder, and each of the wheel cylinders is hydraulically connected with one and only one of the first set of the electromagnetic valves and also one and only one of the second set of the electromagnetic valves.
