brake processing channels configured to control a plurality of electric brake actuators and a plurality of parking brake mechanisms,
the method comprising:
obtaining brake force data for each of the plurality of processing channels, the brake force data indicating actual force
imparted by the plurality of electric brake actuators;
obtaining parking brake lever status data for each of the plurality of processing channels, the parking brake lever status
data indicating position of a parking brake lever of the vehicle;
obtaining parking brake activation data for each of the plurality of processing channels, the parking brake activation data
indicating whether the parking brake mechanisms are active or inactive; and
generating, in response to the brake force data, the parking brake lever status data, and the parking brake activation data,
at least one control signal for the brake status indicator.
