Vehicle torque coordination
First Claim
1. A method for coordinating torque demand amongst a plurality of torque producing devices in an automotive vehicle, the method comprising:
- receiving information defining at least one torque production limitation for a first torque producing device;
determining a request for torque;
comparing the request for torque with the at least one first torque producing device torque production limitation;
if the comparison results in the request for torque exceeding one of the at least one first torque producing device torque production limitation, (a) determining a first excess requested torque as the difference between the request for torque and the exceeded first torque producing device torque production limitation, (b) determining as the first coordinated torque request the exceeded first torque producing device torque production limitation, and (c) determining as the second coordinated torque request the first excess requested torque;
sending the first coordinated torque request to the first torque producing device; and
sending the second coordinated torque request to at least one second torque producing device.

Abstract
Torque demand is coordinated in a vehicle. Information defining at least one torque production limitation for a first torque producing device is received. A request for torque is compared with the first torque producing device torque production limitation. If the comparison does not result in the request for torque exceeding a limitation, a first coordinated torque request is determined as the request for torque and a null torque is determined as a second coordinated torque request. Otherwise, a first excess requested torque is determined as the difference between the request for torque and the exceeded limitation, the first coordinated torque request is determined as the exceeded limitation, and the second coordinated torque request is determined as the first excess requested torque.

10. A vehicle comprising:
-
an engine operative to receive commands for generating a first torque;
at least one motor operative to receive commands for generating a second torque;
at least one source of torque requests; and
control logic in communication with the engine, the at least one motor and the at least one source of torque requests, the control logic operative to (a) determine a torque request, (b) determine as an initial coordinated torque request the determined torque request limited by at least one engine torque limit, (c) determine as a first excess requested torque a difference between the received torque request and the initial coordinated torque request, (d) determine as a second coordinated torque request the first excess requested torque limited by at least one motor torque limit, (e) determine as a second excess requested torque a difference between the first excess requested torque and the second coordinated torque request, and (f) determine as a first coordinated torque request a sum of the initial coordinated torque request and the second excess requested torque. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
