摘要： An electric drive system for a vehicle and method includes controlling a propulsion system of the vehicle to operate according to a first torque-speed relationship between a power generated by an engine and a speed of the engine. The engine is controlled according to the first torque-speed relationship during acceleration of the vehicle by motors that are powered by operation of the engine. The method includes determining that operation of the propulsion system has reached a steady state following the propulsion system operating according to the first torque-speed relationship and controlling the propulsion system to operate according to a second torque-speed relationship between the power and the speed of the engine. The second torque-speed relationship is reduced relative to the first torque-speed relationship such that the engine speed in the first torque-speed relationship is associated with a greater amount of power than in the second torque-speed relationship.

摘要： A computer includes a processor and a memory storing processor-executable instructions. The processor is programmed to prevent a traction battery from providing power to a vehicle powertrain below a charge threshold, and then, upon one of (a) receiving an acceleration demand above an acceleration threshold and (b) predicting that a planned maneuver classified as high acceleration will occur within a time threshold, permit the traction battery to provide power to the vehicle powertrain below the charge threshold.

摘要： A processor unit (3) for model-based predictive control of a vehicle (1) taking into account an arrival time factor is configured to calculate a trajectory for the vehicle (1) based at least in part on at least one arrival time factor, with the trajectory including an entire route (20) to a specified destination (19) at which the vehicle (1) is to arrive, and with the at least one arrival time factor influencing an arrival time of the vehicle (1) at the specified destination (19). Additionally, the processor unit (3) is configured to optimize a section of the trajectory for the vehicle (1) for a sliding prediction horizon by executing a model-based predictive control (MPC) algorithm (13), where the MPC algorithm (13) includes a longitudinal dynamic model (14) of a drive train (7) of the vehicle (1) and a cost function (15) to be minimized.

摘要： Presented are hybrid electric vehicle (HEV) powertrains and control logic for vehicle response management, methods for making/operating HEV powertrains, and motor vehicles equipped with HEV powertrains. A method of controlling a hybrid powertrain includes receiving data indicative of a motor speed of a traction motor and torque commands for the motor, an engine, and an engine disconnect clutch (EDC). A vehicle controller uses a state observer module to estimate a jerk response based on the motor speed, and determines if the EDC is in a torque-transmitting active state. Responsive to the EDC being in the active state, the controller calculates an incremental feedback control signal that is predicted to reduce the estimated jerk based on the engine, motor, and clutch torque commands. One or more torque command signals are transmitted to the engine, motor and/or EDC to modulate a torque output thereof based on the incremental feedback control signal.

摘要： A system and method for controlling a hybrid electric vehicle using a driving tendency are provided. The method includes determining a driving tendency level based on data to determine a driving tendency of a driver and determining a target engine torque using an engine torque map based on a vehicle speed and a required torque. Whether the driving tendency level corresponds to a predetermined level is determined as well as whether the required torque is equal to or greater than a torque that corresponds to an optimal operating point of an engine when the driving tendency level corresponds to the predetermined level. The target engine torque is then adjusted when the required torque is equal to or greater than the torque that corresponds to the optimal operating point of the engine.

摘要： Presented are traction battery pack balancing systems, methods for making/operating such systems, and multi-pack, electric-drive motor vehicles with battery pack balancing capabilities. A method for controlling operation of a motor vehicle includes a vehicle controller: receiving a key-off command signal to power off the motor vehicle; determining if a difference between corresponding electrical characteristics of first and second traction battery packs is greater than a calibrated characteristic differential threshold; determining if a difference between corresponding battery pack capacities of the first and second traction battery packs is greater than a calibrated capacity differential threshold; and, responsive to the characteristic difference not being greater than the calibrated characteristic differential threshold and the capacity difference being greater than the calibrated capacity differential threshold, transmitting a key-on command signal to power on the motor vehicle, and a pack balancing command signal to reduce the capacity difference to below the calibrated capacity differential threshold.

摘要： There is provided a hybrid vehicle that enables user to be more appropriately notified of a control effect by performing a drive support control. A hybrid vehicle includes an engine; a motor; a battery; map information; and a control device programmed to set a drive route from a current location to a destination, to create a drive support plan that assigns one of drive modes including a CD mode and a CS mode to each of drive sections of the drive route, and to perform drive support control that causes the hybrid vehicle to be driven along the drive support plan. The control device accumulates control effect obtained by performing the drive support control and notifies the control effect when the hybrid vehicle reaches the destination. The control device deletes the control effect when the predetermined deletion condition is satisfied.

摘要： A controller is applied to a vehicle including an engine (11) and a motor generator (12 and 13) as power sources of the vehicle and a battery (20) that transfers power with the motor generator. The controller charges the battery with a regeneration power that is a power regenerated by the motor generator when the vehicle is decelerated. The controller includes a SOC prediction unit (39, 50 and 205) to predict a SOC indicating a remaining capacity of the battery in a scheduled travel route of the vehicle, based on a predicted result of a road grade and a vehicle speed in the scheduled travel route, a discharge control unit (39, 52, 206, 208 and 301 to 303) to execute a discharge increasing control to previously increase a discharge quantity of the battery to prevent the battery from becoming in a saturation state based on a predicted SOC that is the SOC predicted by the SOC prediction unit, when the discharge control unit determines that the battery becomes in the saturation state where the battery cannot be charged with the regeneration power based on the predicted SOC, a determination unit (39 and 105 to 109) to determine whether a behavior of the predicted SOC shifts from a behavior of an actual SOC or determine whether a SOC shift factor occurs, after a start of the discharge increasing control, where the SOC shift factor is a vehicle control or an environment change that predicts the behavior of the predicted SOC shifts from the behavior of the actual SOC, and a correction unit (39, 110, 201 to 209 and 301 to 303) to correct the discharge increasing control by executing a prediction of the SOC in the scheduled travel route again, when the determination unit determines that the behavior of the predicted SOC shifts from the behavior of the actual SOC or determines that the SOC shift factor occurs.

摘要： A method and system of operating an internal combustion engine (ICE) of a hybrid powertrain system for powering a vehicle or stationary apparatus having a variable load demand includes arrangements and configurations of operating the ICE to charge/recharge capacitive energy storage, such as ultra-capacitors, during acceleration or high load demand on the ICE. Operation of the ICE can be transitioned from one mode of operation to another, more efficient, mode of operation during charging and high load. The present invention provides fuel efficiency/economy benefits when charging the capacitive energy storage during high load situations.
