Increased capability modular vehicle-dynamics control architecture
First Claim
1. A system for controlling an amount of torque generated by at least one torque generating device in a vehicle, the system comprising:
- a vehicle layer configured to transmit at least one arbitrated torque request signal indicative of first and second amounts of torque desired by at least one of a driver and a vehicle-dynamic system and at least one torque reservation request signal indicative of whether the vehicle is in at least one of an anticipated vehicle dynamic state and a non-anticipated vehicle dynamic state; and
a coordination layer configured to;
control the at least one torque generating device to generate the first amount of torque in response to the at least one arbitrated torque request signal and the at least one torque reservation request signal indicating that the vehicle is in the non-anticipated vehicle dynamic state; and
control the at least one torque generating device to generate the second amount of torque in response to the at least one arbitrated torque request signal and the at least one torque reservation request signal indicating that the vehicle is in the anticipated vehicle dynamic state,wherein the coordination layer controls the at least one torque generating device to operate at a predetermined operation level to generate the second amount of torque.

Abstract
A system and method for controlling the amount of torque generated by at least one torque generating device in a vehicle is provided. A vehicle layer transmits arbitrated torque request signals indicative of first and second amounts of torque and at least one torque reservation request signal indicative of whether the vehicle is in an anticipated vehicle dynamic state or in a non-anticipated vehicle dynamic state. A coordination layer controls the torque generating device to generate the first amount of torque in response to the arbitrated torque request signal and the torque reservation request signal indicating that the vehicle is in the non-anticipated vehicle dynamic state. The coordination layer controls torque generating device to generate the second amount of torque in response to the arbitrated torque request signal and the torque reservation request signal indicating that the vehicle is in the anticipated vehicle dynamic state.

11. A method for controlling an amount of torque generated by at least one torque generating device in a vehicle, the method comprising:
-
receiving at least one arbitrated torque request signal indicative of first and second amounts of torque desired by at least one of a driver and a vehicle-dynamic system; receiving at least one torque reservation request signal indicative of whether the vehicle is in at least one of an anticipated vehicle dynamic state and a non-anticipated vehicle dynamic state; controlling the at least one torque generating device to generate the first amount of torque in response to the at least one arbitrated torque request signal and the at least one torque reservation request signal indicating that the vehicle is in the non-anticipated vehicle dynamic state; and controlling the at least one torque generating device to generate the second amount of torque in response to the at least one arbitrated torque request signal and the at least one torque reservation request signal indicating that the vehicle is in the anticipated vehicle dynamic state, wherein the at least one torque generating device is controlled to operate at a predetermined operation level to generate the second amount of torque. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A system for controlling an amount of torque generated by at least one torque generating device in a vehicle, the system comprising:
-
a vehicle layer configured to transmit at least one arbitrated torque request signal indicative of a first amount of torque and a second amount of torque desired by at least one of a driver and a vehicle-dynamic system and at least one torque reservation request signal indicative of whether the vehicle is in at least one of an anticipated vehicle dynamic state and a non-anticipated vehicle dynamic state, and a coordination layer configured to; control the at least one torque generating device to generate the first amount of torque within a first predetermined response time in response to the at least one arbitrated torque request signal and the at least one torque reservation request signal indicating that the vehicle is in the non-anticipated vehicle dynamic state; and control the at least one torque generating device to generate the second amount of torque within a second predetermined response time in response to the at least one arbitrated torque request signal and the at least one torque reservation request signal indicating that the vehicle is in the anticipated vehicle dynamic state, wherein the first and second predetermined response times are different from one another.
