摘要： A method for controlling a hybrid powertrain includes the following steps: receiving a torque request; determining a plurality of possible motor torques for the first and second electric machines capable of achieving the torque requested; determining system power losses of the powertrain for all the possible motor torques for the first and second electric machines capable of achieving the torque requested; determining a lowest power loss of the system power losses determined for the plurality of possible motor torques for the first and second electric machines; determining a first operating torque for the first electric machine and a second operating torque for the second electric machine that correspond with the lowest power loss; and commanding the first electric machine to generate the first operating torque and the second electric machine to generate the second operating torque in order to achieve the torque requested while minimizing the system power losses.

摘要： A method of estimating soot loading in a diesel particulate filter (DPF) in a vehicle exhaust system includes estimating an engine-out soot rate using a first neural network that has a first set of vehicle operating conditions as inputs. The method further includes estimating DPF soot loading using a second neural network that has the estimated engine-out soot rate from the first neural network and a second set of vehicle operating conditions as inputs. Estimating the engine-out soot rate and estimating the DPF soot loading are performed by an electronic controller that executes the first and the second neural networks. The method also provides for training the first and second neural networks both offline (for initial settings of the neural networks in the vehicle), and online (when the vehicle is being used by a vehicle operator). An exhaust system has a controller that implements the method.

摘要： A vehicle includes a vehicle body having a first body end configured to face oncoming ambient airflow when the vehicle is in motion relative to a road surface, and also having a second body end opposite of the first body end. The vehicle also includes first and second lateral body sides disposed generally parallel to one another. The vehicle additionally includes first and second side panels mounted to the vehicle body and configured to selectively deploy into ambient airflow aft of the second body end to become positioned along the respective first and second lateral body sides and retract from the ambient airflow. The first and second side panels provide an active lengthening of the vehicle body aft of the second body end to thereby reduce aerodynamic drag when both side panels are deployed and positioned along the respective first and second lateral body sides.

摘要： A vehicle includes a body that extends along a longitudinal axis, between a forward end and a rearward end. A front bumper assembly is disposed at the forward end of the body. The front bumper assembly includes a B-shaped structure that defines a channel that extends transversely across the body, relative to the longitudinal axis. A heat exchanger is disposed within the channel of the bumper structure. The heat exchanger is operable to transfer heat from a fluid circulating through the heat exchanger to a flow of air passing across the heat exchanger. The fluid may include, but is not limited to, engine oil, transmission fluid, power steering fluid, or an engine coolant from a low temperature coolant loop.

摘要： A hybrid powertrain for propelling a vehicle includes an engine and an energy storage system operatively connected to the engine. Both the engine and the energy storage system are operable for providing power to propel the vehicle. A control system is operatively connected to the engine and the energy storage system and is configured to execute a stored algorithm that determines required energy reserve, remaining energy, and power capability of the energy storage system. The control system commands operation in one of a first operating mode, a second operating mode, and a third operating mode based on the required energy reserve, the remaining energy, and the power capability of the energy storage system.

摘要： A system includes a fluid pump, a hydraulic accumulator, and a controller. The controller calculates a reserve volume of the accumulator as a function of a component volume, leakage in the system, and a displacement of the pump, and executes a control action using the calculated reserve volume. The system may be a vehicle having input clutches and a dual clutch transmission (DCT) having gear forks. In such an embodiment, the accumulator and pump supply fluid pressure to the input clutches and gear forks in response to control signals from the controller. The controller executes a method that includes calculating the reserve volume of the accumulator as a function of a component volume, a volume of leakage in the system, and a displacement of the fluid pump. The method also includes executing a shift of the DCT using the calculated reserve volume.
