A method for implementing torque control using a Neural Network (NN) for a torque prediction model to receive a set of measured vehicle operating inputs associated with torque prediction; substituting a set of multiple independent variables into the torque prediction model so that the NN is then taking the form of a simplified pseudo-NN that contains a reduced variable set of one independent variable; processing, the set of measured vehicle operating inputs by the pseudo-NN based on the NN prediction model by using only one independent variable in a pseudo-NN's simplified mathematical expression; and solving for at least one root of the pseudo-NN's simplified mathematical expression by obtaining a root value without having to rely on an inversion operation of a mathematical expression that consists of an entire set of independent variables.

A current limiting method of a fuel cell stack is capable of preventing current of the fuel cell stack from rapidly dropping to prevent jerking or shock from occurring while a vehicle travels. The method includes: determining whether performance deterioration of a unit cell of the fuel cell stack has occurred, employing a feed forward control type current limiting logic of the fuel cell stack before an output of the fuel cell vehicle is lowered, decreasing the current of the fuel cell stack to a predetermined level by the feed forward control type current limiting logic, and gradually restoring the current of the fuel cell stack to a maximum current usage value from a point in time when the current of a load is used.

A method for operating an electrically operated or also electrically operable motor vehicle provided with a rechargeable electric energy storage device associated with the drive motor of the motor vehicle. A target charging state is determined for the energy storage device and an operating strategy is determined for a route that is calculated, entered or predicted for the next trip, by which recuperative deceleration is enabled with a specifiable minimum amount for deceleration processes occurring along the route. A total mass of the motor vehicle, including optionally a trailer connected to the motor vehicle, deviating from an input normal value and an air resistance of the motor vehicle deviating from a predetermined normal value are taken into account.

An electronic control unit is configured to select one of a series mode, a series-parallel mode and a parallel mode as a running mode. A load level of a hybrid vehicle is set to a value that is high in the order of a load level at which the parallel mode is selected, a load level at which the series-parallel mode is selected, and a load level at which the series mode is selected. That is, the electronic control unit selects the series-parallel mode in an intermediate load region, selects the series mode in a low load region, and selects the parallel mode in a high load region.

A method for distributing electrical power to electric motors in an electric powertrain, in which the electric motors are electrically connected to a shared power supply, includes receiving input signals via a supervisory controller. The input signals include a total torque request of the electric powertrain and electrical limits of the power supply. The method includes determining an open-loop torque command for each respective motor in response to the input signals. In response to the total torque request and the power supply limits, the controller also determines maximum and minimum power limits of motor, with the maximum and minimum power limits including a calibrated power reserve for executing a predetermined torque operation. The method includes transmitting the open-loop torque command and the power limits to a respective motor control processor of each motor to thereby control the torque operation.

An electric vehicle thermal management system and method utilizing power demand models for both propulsion and auxiliary systems, and an intelligent thermal load management module. A navigation unit formulates potential routes to a destination that is either set by a driver or predicted by a drive cycle prediction module. The routes are used to inform the propulsion power demand model, while historical driving patterns based on GPS data and time-dependent climate inputs inform the auxiliary power demand model. The expected power demands for the individual systems and overall combined system are accounted for in calculations performed by optimization algorithms in an intelligent thermal load management module. The calculations produce desired temperature setpoints which send heating and cooling requests to refrigerant and coolant fluid handlers and subsequent actuators that control the refrigerant and coolant fluid loops.

An electrified vehicle includes a traction battery, an engine, and a controller. The controller is configured to generate a request for the engine in response to an input passing a threshold and to adjust the threshold when a state of health (SOH) of the traction battery is at a chance of violating a target, such as a warranty target. The request for the engine may be an engine pull up (EPU) request for starting the engine with the threshold being an EPU threshold in which case the controller lowers the EPU threshold when the battery SOH is at a chance of violating the target. The request for the engine may be an engine pull down (EPD) request for stopping the engine with the threshold being an EPD threshold in which case the controller lowers the EPD threshold when the battery SOH is at a chance of violating the target.

An apparatus is provided for adjusting an electrical configuration of a plurality of components of an electrical network associated with a vehicle in order to tune electrical characteristics of the electrical network to continuously match a dynamically changing desired mode of operation of the electrical network associated with the vehicle.

A control method controls an electric four-wheel-drive vehicle to switch a drive torque distribution between a first distribution prioritizing energy efficiency and a second distribution prioritizing driving performance. The distribution is set to the second distribution where wheel slip is detected during a trip, and returned to the first distribution once the vehicle has stopped. When wheel slip is detected at least during acceleration, the distribution is switched from the first distribution to the second distribution. When wheel slip is detected during deceleration, a slip experience flag is set. The slip experience flag is maintained at least until starting off in a subsequent trip. Where the slip experience flag has been set, the distribution is maintained as the second distribution when the vehicle has stopped, and where the slip experience flag has not been set, the distribution is returned to the first distribution upon the vehicle being stopped.
