Abstract
A method is provided for arranging the components and power connection points within an electromechanical braking system architecture in order to better maintain isolation of the power busses, and thereby improve overall integrity of the system, while still meeting system redundancy, performance and safety requirements as in the past. In addition, a method is provided for connecting and efficiently using available power in emergency braking and parking modes.
Claims11
A method for distributing power to an electromechanical braking system comprising a plurality of brake actuators for effecting a braking torque on wheels of a vehicle, a plurality of electromechanical actuator controllers (EMACs) for providing drive control of the brake actuators in response to brake command signals, and at least one brake control unit (BSCU) for converting an input brake command signal into the brake command signals which are provided to the EMACs, the method comprising:
- configuring at least two of the plurality of EMACs to function redundantly in providing drive control to the brake actuators of a same wheel in response to the brake command signals;
- and
- providing power to the at least two EMACs via respective power busses having different power sources.
A method for distributing power to an electromechanical braking system comprising a plurality of brake actuators for effecting a braking torque on wheels of a vehicle, at least one electromechanical actuator controller (EMAC) for providing drive control of the brake actuators in response to brake command signals, and a plurality of brake control units (BSCUs) for converting an input brake command signal into the brake command signals which are provided to the at least one EMAC, the method comprising:
- configuring at least two of the plurality of BSCUs to function redundantly in providing brake command signals directly to the at least one EMAC in response to the input brake command signal;
- and
- providing power to the at least two BSCUs via respective power busses having different power sources.
A method for controlling braking in an electromechanical braking system comprising at least one brake actuator for effecting a braking torque on a wheel of a vehicle, at least one electromechanical actuator controller (EMAC) for providing drive control of the brake actuator in response to brake command signals, and at least one brake control unit (BSCU) for converting an input brake command signal into the brake command signals which are provided to the EMAC, the BSCU providing antiskid operations in relation to the input brake command signal, the method comprising:
- under predefined normal braking conditions, inputting the input brake command signal to the BSCU to obtain a brake command signal which is provided to the EMAC to implement braking;
- and
- under predefined parking conditions, inputting the input brake command signal directly to the EMAC so as to bypass the BSCU and implement braking.
