Entering and exiting ECP mode for an integrated ECP/EAB system
First Claim
1. A method of transitioning between pneumatic and electric modes of an integrated pneumatic/electro-pneumatic train brake system including a brake control having a common operator brake controller, the method comprising:
- initially, the control applies the brakes in response to the operator brake controller in the present mode;
the control enables the next mode upon a request from an operator and applies the brakes in the next mode to at least a level of the applied brakes in the present mode;
once the control verifies that the next mode is set up and upon request from the operator, the brakes are released in the present mode only; and
once the present mode brakes are released, the control and the brake system switch to the next mode.

Abstract
A method of transitioning between the pneumatic and electric modes of an integrated pneumatic/electro-pneumatic train brake system which includes a brake control having a common operator brake controller. Initially, the control applies the brakes in response to the operator brake controller in the present mode. The control enables the next mode upon request from the operator and applies the brakes in the next mode to match the applied brakes in the present mode. Once the present mode brake is released, the control and system switch to the next mode. Other brake controllers monitor the network and automatically switches modes based on the status of the network.

19. A method of transitioning between pneumatic and electric modes of an integrated pneumatic/electro-pneumatic brake train brake system, the brake system includes a plurality of brake controls in a network, the method comprising:
-
switching one of the brake controls to an electric mode;
activating the network by the one brake control in the electric mode; and
each of the other brake controls monitoring the network and switching themselves to the electric mode upon determining that the network is activated.

26. A method of transitioning from a pneumatic mode to an electric mode of an integrated pneumatic/electro-pneumatic train brake system including a brake control having a common operator brake controller, the method comprising:
-
initially, the control applies the brakes in response to the operator brake controller in the pneumatic mode the control enables the electric mode upon a request from an operator and applies the brakes in the electric mode to at least the valve of the applied brakes in the pneumatic mode;
once the control verifies that the electric mode is set up, the operator using the brake controller releases the brakes in the pneumatic mode only; and
once the pneumatic mode brakes are released, the control and the brake system switch to the electric mode.

27. A method of transitioning from an electric mode to a pneumatic mode of an integrated pneumatic/electro-pneumatic train brake system including a brake control having a common operator brake controller, the method comprising:
-
initially, the control applies the brakes in response to the operator brake controller in the electric mode;
the control enables the pneumatic mode upon a first electric mode cut-out request from an operator and applies the brakes in the electric mode to at least the valve of the applied brakes in the pneumatic mode;
the control releases the brakes in the electric mode only after verifying that the pneumatic mode is set up and upon receipt of a second cut-out request from the operator; and
once the electric mode brakes are released, the control and the brake system switch to the pneumatic mode.
