A vehicle includes an engine, an electric machine, and a controller. The engine and the electric machine are configured to simultaneously generate power in a hybrid mode. The controller is programmed to, responsive to a power demand decreasing to less than a first threshold while the vehicle is operating in the hybrid mode, shutdown the engine. The controller is further programmed to, responsive to the power demand decreasing to less than the first threshold and an operator input to extend the hybrid mode, override shutting down the engine.

Hybrid vehicle engine start/stop system

Systems and methods for operating a spark ignition engine that includes a particulate filter in the engine's exhaust system are described. In one example, the spark ignition engine is prevented from exceeding a threshold engine load when the engine is supplying power to an electric machine so that engine emissions may be reduced.

Methods and system for operating an engine

A method includes controlling an electrified vehicle by automatically commanding an output torque from an electric machine if the electrified vehicle is in park and an engine start or stop request has been received. A road grade may be used to determine whether or not to command the output torque.

Vehicle systems and methods for avoiding unintentional electrified vehicle movement and for reducing electrified vehicle noise, vibration, and harshness

Systems and methods for operating a spark ignition engine that includes a particulate filter in the engine's exhaust system are described. In one example, a threshold temperature at which the spark ignition engine may be automatically stopped is adjusted according to an amount of soot that is stored in the particulate filter.

Methods and system for automatically stopping an engine

A vehicle includes an engine, an electric machine, and a controller. The engine and the electric machine are each configured to generate power. The controller is programmed to, responsive to a power demand exceeding a first threshold while the electric machine is generating power alone, start the engine. The controller is further programmed to, responsive to the power demand exceeding the first threshold and an operator input to suppress an engine startup, override starting the engine for a predetermined period of time.

Methods and systems for a vehicle such as a plug-in hybrid electric vehicle (PHEV) having a traction battery are for improving the drivability of the vehicle the battery has low discharge limits. The battery may have such low discharge limits due to the battery being cold and/or the battery state-of-charge (SOC) being low. In operation, upon the battery having a discharge limit lower than a threshold while the vehicle is operating in a charge sustain mode, the engine of the vehicle is used to charge the battery to increase the SOC of the battery such that the battery has a discharge limit greater than the threshold. The vehicle is operated in the charge sustain mode using the battery with the increased SOC.

Method and system for improving drivability of PHEV having low traction battery discharge limits

An exemplary electrified vehicle assembly includes a battery pack, a cabin heater, and a coolant loop that communicates liquid coolant from the battery pack to the cabin heater. The cabin heater configured to heat a cabin of a vehicle with thermal energy from liquid coolant.

Electrified vehicle cabin heating

A method includes controlling an electrified vehicle by automatically engaging a braking device if the electrified vehicle is in park and an engine start or stop request has been received. Controlling the electrified vehicle includes preventing a brake lamp from illuminating during engagement of the braking device.

Vehicle systems and methods for reducing electrified vehicle noise, vibration, and harshness

An exemplary electrified vehicle assembly includes a coolant circuit and a controller configured to selectively direct energy into at least one component of the coolant circuit to provide a negative wheel torque.

Electrified vehicle energy dissipation

An electrified vehicle according to an exemplary aspect of the present disclosure includes, among other things, an energy recovery mechanism, and a controller configured to selectively activate at least a battery cooling mode to dissipate excess power from the energy recovery mechanism.

Electrified vehicle with power dissipation feature

A hybrid vehicle includes a traction battery having a battery fan, an engine, an electric machine coupled to the battery, and a controller or at least one powertrain module having a controller. The controller is programmed to respond to a change in a user selected powertrain operating mode to a performance mode. This change may occur while a pedal demand is generally constant. The controller may increase an available power of the battery to drive the electric machine without altering state of charge operating limits of the battery. The increase in available power of the battery may include increasing a state of charge of the battery or reducing the battery temperature such that a current may flow from the battery for a longer time period. Also, the overall available power for the vehicle may include operation of the engine at a higher rotational speed.

Vehicle performance preload enabler

A system and method for determining functionality of a single signal wire actuator of a vehicle monitor the signal wire for a heartbeat signal after commanding the actuator and waiting for a self-diagnostic period. In one embodiment, a hybrid vehicle includes an engine, an electric heater, a heater core and a valve positioned to route coolant through an engine and/or an electric heater. An actuator positioned to circulate coolant through the electric heater and the heater core is configured to transmit a heartbeat signal while connected to a power source and a ground terminal. A vehicle controller may be configured to store a diagnostic code, start the engine and/or control the valve to selectively route coolant through the engine and the heater core in response to a heat request and the heartbeat signal not being received from the actuator within a predetermined interval of time.
