Abstract
An arrangement is provided for controlling a motor vehicle powertrain. The controller comprises means for measuring an operator request for acceleration, and means for controlling the component as a function of the operator request for acceleration.
Claims13
A method of controlling a motor vehicle powertrain system, the method comprising:
- receiving an input indicative of an operator request for acceleration;
- and
- controlling a plurality of powertrain components as a function of the input so as to maximize powertrain responsiveness using a control strategy that mediates competing torque demands among the plurality of components so that the operator request is prioritized as a core control parameter, wherein mediating the competing torque demands comprises determining other powertain component torque demands and using an optimizer routine having hierarchical weighted control laws to determine an optimized target before issuing a torque command to a torque provider.
The method of claim 3, wherein receiving an input comprises measuring a change in throttle position with an electronic throttle controller.
A powertrain controller for controlling a vehicle powertrain system, the controller comprising:
- a control module arranged to receive an input indicative of an operator request for acceleration;
- and
- a processor arranged to control a plurality of components in the vehicle powertrain system as a function of the request so as to maximize powertrain responsiveness using a control strategy that mediates competing torque demands among the plurality of components so that the operator request is prioritized as a core control parameter, wherein the processor is arranged to mediate between the competing torque demands by determining other powertrain component torque demands and using an optimizer routine having hierarchical weighted control laws to determine an optimized target before issuing a torque command to a torque provider.
