The invention discloses a pressure sensing electronic brake power assisting device and control, and belongs to the field of automobile electronic accessories. The controller drives the motor according to signals of the pressure sensor, the motor drives the ejector rod to do linear reciprocating motion in the shell through the reduction gear set, the brake master pump is arranged at the front end of the ejector rod, the ejector rod ejects a piston of the brake master pump to do reciprocating work, and a return spring is arranged between the front end of the ejector rod and the master pump. A pipe cavity structure is arranged at the tail of the brake ejector rod, a pressure sensor is arranged at the bottom of a pipe cavity, and a push rod return spring, a piston and a push rod are sequentially arranged on the right side of the pressure sensor. The pressure sensor generates direct proportion linear signals according to the magnitude of piston force to drive the controller, and the controller sets three working states according to the magnitude of the signals, namely a closing state smaller than an A value, a keeping state larger than the A value and smaller than a B value and a propelling state larger than the B value.
