摘要： An electrified vehicle includes a human-machine interface to enable towed vehicle mode and specify a desired traction battery charge upon arrival at a destination. A controller is programmed to vary charging rate of the traction battery while the electrified vehicle is being towed over a user-specified distance to the destination to obtain the user-specified target charge for the traction battery upon reaching the destination. The target charge may be entered as a percentage state of charge (SOC), a distance to empty (DTE), or Watt hours, and converted to net energy input required for the traction battery. The controller distributes the charging load over the entire distance to reduce the affect on the drivability and efficiency of the towing vehicle by varying regenerative braking of the electric machine(s) while being towed to provide a net energy needed to obtain the target charge upon reaching the destination.

摘要： An electrified vehicle includes an electric machine, a traction battery selectively connected to the electric machine, a human-machine interface (HMI), and a controller programmed to, after receiving a signal from the HMI enabling towed vehicle operation of the electrified vehicle, control the electric machine to generate a regenerative braking torque in response to deceleration of the electrified vehicle exceeding an associated deceleration threshold and road grade being below a road grade threshold. The controller may also be programmed to control friction brakes of the electrified vehicle in response to the deceleration exceeding the associated threshold. The controller may control brake lights of the electrified vehicle in response to the regenerative braking and/or friction braking. Regenerative and friction braking may be released in response to acceleration exceeding a corresponding threshold.

摘要： Systems and methods are provided for coordinating and controlling power flow during bidirectional energy transfer events between an electrified vehicle and one or more charging trailers. The systems and methods may prioritize energy transfers between each connected energy based on a charge priority selection that may be manually input by a user of the system. Charge energy may be transferred to the appropriate energy unit using such a manual approach to meet customer needs with varying levels of priority according to an energy transfer prioritization control strategy that is derived from various inputs that are considered.

摘要： An electrified vehicle includes a human-machine interface to enable a towed vehicle mode to enable electric pumps to lubricate and/or cool vehicle components and to disable driver assistance features while the electrified vehicle is being towed by another vehicle. The electrified vehicle includes a drivetrain having an electric machine configured to provide propulsive torque to vehicle wheels, a high-voltage traction battery selectively connected to the electric machine, a battery powered fluid pump configured to pump fluid to the drivetrain, and a controller programmed to, after receiving a signal enabling towed vehicle operation of the electrified vehicle, control operation of the battery powered fluid pump while the electrified vehicle is being towed. The controller may disable one or more driver assistance features and alerts such as automatic emergency braking, automatic shifting of the drivetrain, automatic parking brake operation, automatic headlights, automatic steering, cruise control, parking assistance, and external object distance detection.

摘要： Systems and methods are provided for coordinating and providing bidirectional energy transfer events between electrified vehicles and households or other structures, such as for supporting household loads associated with the structures during power outage conditions. In some implementations, available energy may be rationed from the vehicle to the structure based on a power outage restoration estimate. Rather than supporting household loads with constant energy during power outage conditions, the disclosed systems/methods may provide strategic rationing of bidirectional energy transfer in order to extend appliance operation for the duration of power outage conditions.

摘要： A vehicle includes a battery, an electric machine, an electrical outlet, and a controller. The electric machine is configured to charge the battery. The electrical outlet is configured to draw power from the battery to power an external device. The controller is programmed to adjust a rate at which the electric machine charges the battery based on a power consumption at the electrical outlet exceeding a threshold and a battery degradation value.

摘要： A vehicle has an engine, an exhaust aftertreatment system, an electric machine, and a controller configured to, in response to an actual engine torque output being less than an inferred engine torque, shut down the engine. A vehicle has an engine, an exhaust aftertreatment system, an electric machine, and a controller configured to, in response to an actual engine torque output being less than a first threshold and a torque request to the engine being greater than a second threshold, set a diagnostic code. A method includes receiving an actual engine torque output, receiving an engine torque request, and shutting down the engine when the actual engine torque output is less than a first threshold and the engine torque request is greater than a second threshold for a predetermined time period to limit temperature increase of a catalyst.

摘要： A power management system for a vehicle having wheels and an electric machine operable to provide torque to drive at least one of the wheels includes a first energy storage system capable of supplying power to operate the electric machine. The system also includes a second energy storage system capable of supplying power directly to at least one vehicle load at a lower voltage than the first energy storage system. A voltage conversion device is operable to reduce a voltage of the power supplied by the first energy storage system to the lower voltage to charge the second energy storage system when the vehicle is in a key-off state.

摘要： A system and method are disclosed for charging a depleted battery within a first hybrid vehicle when connected to a second hybrid vehicle using a junction box. The system may include a wire harness having high voltage interlock connectors (HVIL) and high voltage (HV) connectors that connected to both the first vehicle and second vehicle. The system may also include one or more controllers that engage the charged battery to start a first engine within the first vehicle or, alternatively, a second engine within the second vehicle. After the first engine or second engine is started, the charged battery will be disconnected and the depleted battery may be connected using a set of HV contactors. The first engine or the second engine may then be operated to charge the depleted battery. Charging may stop when the depleted battery is charged within a specified SoC range.

摘要： A vehicle includes a battery control module and a controller. The battery control module may be configured to issue at regular intervals a message indicative of an SOC of a battery. The controller may be configured to, in an absence of receiving the messages at the regular intervals while in a key-on state and a torque demand is present, restrict power flow between the battery and an electric powertrain to a limit that is based on a predicted SOC to provide limited propulsive force.
