Abstract
The present disclosure includes the use of a smart load cell in a system for controlling an electromechanical actuator. A load cell may be positioned along the outer surface of the electromechanical actuator. Further, the load cell may utilize strain gages and a microcontroller. The load cell may be configured to transmit data to an electric brake actuator controller which includes calibration for operating temperature of the electromechanical actuator.
Claims6
A method for controlling an electromechanical actuator system, comprising:
- calibrating a load cell of an electromechanical actuator,
- wherein the load cell comprises:
- a circuit board coupled to the electromechanical actuator, a bridge including a strain gauge coupled to a housing of the electromechanical actuator,
- wherein the strain gauge is disposed within a channel of an outer surface of the housing of the electromechanical actuator,
- a microcontroller configured to receive data from the bridge,
- and an output drive circuit in communication with the microcontroller;
- and
- transmitting an output signal from the output drive circuit to an electric brake actuator controller.
