Abstract
Systems and methods of controlling a brake system are provided. The system may include the step of detecting, by a controller, a failure of a first load cell of a first electromechanical brake actuator (EBA). The method may further comprise estimating, by the controller, a force of the first EBA using a force output from a second load cell, and commanding, by the controller, the first EBA in response to the estimated force of the first EBA.
Claims20
A brake system comprising:
- an electromechanical brake actuator controller (EBAC);
- a first electromechanical brake actuator (EBA) electrically coupled to the EBAC, the first EBA comprising a first load cell;
- a second EBA electrically coupled to the EBAC, the second EBA comprising a second load cell that outputs a force output;
- a tangible, non-transitory memory configured to communicate with a controller of at least one of the first EBA or the EBAC, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the controller, cause the controller to perform operations comprising:
- detecting, by the controller, a failure of the first load cell;
- estimating, by the controller, a force of the first EBA using the force output from the second load cell;
- and
- commanding, by the controller, the first EBA in response to the force output from the second load cell.
A method of controlling a brake system comprising:
- detecting, by a controller, a failure of a first load cell of a first electromechanical brake actuator (EBA);
- estimating, by the controller, a force output of the first EBA using a force output from a second load cell;
- and
- commanding, by the controller, the first EBA in response to the estimated force output of the first EBA.
A non-transitory medium having instructions stored thereon that, in response to execution by an electromechanical brake actuator controller (EBAC), cause the EBAC to perform operations comprising:
- detecting, by the EBAC, a failure of a first load cell of a first electromechanical brake actuator (EBA);
- estimating, by the EBAC, a force output of the first EBA using a force output from a second load cell;
- and
- commanding, by the EBAC, the first EBA in response to the estimated force output of the first EBA.
