Abstract: A braking assembly (102) and method for use with a brake by wire system provides braking forces to first and second wheels (104, 106) as a function of first and second electrical brake signals. A first hydraulic brake assembly (108) coupled to the first wheel (104) applies a first braking force to the first wheel (104). A second hydraulic brake assembly (110) coupled to the second wheel (106) applies a second braking force to the second wheel (106). A first pressure sensor (112) senses a pressure of the first hydraulic brake assembly (108) and responsively produces a first pressure signal. A second pressure sensor (114) senses a pressure of the second hydraulic brake assembly (110) and responsively produces a second pressure signal. A controller (116) receives a desired brake actuation signal and responsively determines the first and second electrical brake signals. The controller also receives the first and second pressure signals, responsively detects a non-linear condition of the braking assembly (102) and responsively modifies at least one of the first and second electrical brake signals in response to detecting the non-linear condition.

Abstract: A force generating apparatus provides a force to a moving element upon receipt of an electrical force signal. The force generating apparatus includes a force applying element coupled to the moving element for applying the force to the moving element and an actuator coupled to the force applying element for actuation thereof in response to receiving the electrical force signal. The force generating apparatus further includes a controller for receiving a desired force actuation signal, determining a parameter of the desired force actuation signal, selecting a set of gains based on the parameter, applying the set of gains to a linear control function, determining the electrical force signal as a function of the non-linear control function, and sending the electrical force signal to the actuator.

Abstract: The problem of maintaining fluid modulus during a fast mode release of fluid pressure in a force generating apparatus having a force generating actuator fluidically coupled to a force generating device is solved by limiting the rate at which the actuator can reduce fluid pressure in an apply chamber of the actuator to a rate low enough to preclude a change in modulus of the fluid during the fast mode release.
