Abstract
An illustrative example embodiment of a method of communicating between controllers on a vehicle includes communicating a first operation request from a first controller to a second controller. The first operation request is indicative of the second controller performing a first operation. The second controller attempts to perform the first operation at a time when it cannot be performed, determines that the first operation cannot be performed, and communicates an indication that the first operation request cannot currently be satisfied. The second controller continues to attempt to perform the first operation at a subsequent time.
Claims19
A method of communicating between controllers on a vehicle, the method comprising:
- communicating a first operation request from a first controller on the vehicle to a second controller on the vehicle, the first operation request being indicative of the second controller performing a first operation;
- attempting to perform the first operation by the second controller at a first time when the first operation cannot be performed by the second controller;
- determining, at the second controller, that the first operation cannot be performed at the first time;
- communicating an indication from the second controller to the first controller that the first operation request cannot currently be satisfied;
- and
- attempting to perform the first operation by the second controller again at a second time subsequent to the first time.
A control apparatus for controlling at least one feature of a vehicle, the control apparatus comprising:
- communication means for receiving operation requests and transmitting responses to received operation requests;
- and
- a controller configured to:
- attempt to satisfy a received operation request at a first time when the received operation request cannot be satisfied,
- determine that the received operation request cannot be satisfied at the first time,
- cause the communication means to transmit an indication that the received operation request currently cannot be satisfied, and
- attempt to satisfy the operation request at a second time subsequent to the first time.
A system, comprising:
- a first controller on a vehicle;
- and
- a second controller on a vehicle;
- wherein the first controller is configured to communicate to the second controller an operation request indicative of a first operation to be performed by the second controller;
- and
- the second controller is configured to
- attempt to perform the first operation at a first time when the first operation cannot be performed,
- determine that the operation request cannot currently be satisfied,
- communicate to the first controller an indication that the operation request cannot currently be satisfied, and
- continue to attempt to perform the first operation at a second time subsequent to the first time.
