    摘要： A hybrid vehicle and method of control are associated with the following operation. A quantized previous engine power command based on a previous engine power command is obtained. A current engine power command is quantized. The quantized current engine power command is maintained if the magnitude of the difference between the current engine power command and the quantized previous engine power command is larger than a threshold. The quantized current engine power command is set equal to the quantized previous engine power command if the magnitude of the difference between the current engine power command and the quantized previous engine power command is smaller than the threshold. An output engine power command based on the quantized current engine power command is generated. An engine of the hybrid vehicle is operated based on the output engine power command.

    摘要： 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.

    摘要： A method and system for limiting a fast transient in an engine in a hybrid vehicle is provided. The predicted fuel loss percentage is calculated from an inferred air-fuel ratio (inferred lambda). The rate limit term is calculated from a measured air-fuel ratio (measured lambda) and an engine torque command change rate. The predicted fuel loss percentage and the rate limit term are inputs into a calibration table to determine an engine power rate limit and an engine torque rate limit. An engine torque command is limited using the engine torque rate limit to control a fast engine torque transient for an engine. An engine power command is limited using the engine power rate limit to control the fast engine power transient for the engine.

    摘要： In at least one embodiment, a device for controlling an amount of torque generated by a powertrain in a vehicle is provided. The controller is configured to receive a driver status signal indicative of the status of the driver, a driver condition signal indicative of the driving conditions of the vehicle, and a driver mode signal indicative of the driving mode of the vehicle. The controller is further configured to control the powertrain to adjust the amount of torque that is generated based on the driver status signal, the driver condition signal, and the driver mode signal.
