A vehicle includes a powertrain having an electric machine and a controller. The controller is programmed to, responsive to an accelerator pedal position exceeding a first threshold for a predetermined time period or a lateral acceleration of the vehicle being greater than a second threshold, transition the powertrain from a nominal driving mode to a performance driving mode. The controller is also programmed to, responsive to an increase in a steering wheel angle while in the nominal mode, maintain a power output of the electric machine at a driver demanded power defined by the accelerator pedal position. The controller is further programmed to, responsive to an increase in a steering wheel angle while in the performance driving mode, reduce a power output of the electric machine to less than the driver demanded power.

Hybrid/electric vehicle control system

A vehicle includes an engine and a controller. The controller may be configured to, responsive to indication of a temperature of a starter-generator exceeding a de-rated threshold, command the engine to start and disable engine automatic shut-off. And the controller may be configured to, responsive to indication of the temperature exceeding a disabled threshold, or the temperature exceeding the de-rated threshold and a traction battery discharge power being less than a threshold, command the engine to start and shed a load.

Engine operation based on integrated starter-generator temperature

A computer-implemented method includes, responsive to absence of a motor controller receiving communication packets for a predetermined time during a drive cycle, operating by the controller (i) an inverter to output voltage at a setpoint defined by an inverter terminal voltage at expiration of the predetermined time, and (ii) a motor coupled with the inverter to apply torque according to a change in the voltage.

Autonomous motor control during loss of motor communications

Systems and methods for operating a hybrid powertrain that includes an engine and a motor/generator are described. The systems and methods provide a way of determining whether or not an engine has stalled while a vehicle may be propelled via the motor/generator. In one example, an engine stall may be indicated responsive to a first estimated engine torque and a second estimated engine torque.

Methods and system for detecting engine stall

A hybrid electric vehicle includes an internal combustion engine configured to provide power to traction wheels, and a controller. The controller is configured to, in response to the engine being off and a power request exceeding an engine-start threshold, delay an engine start when vehicle speed is below a predetermined value. Delaying an engine start may include providing an engine-start-threshold offset. The offset decreases as vehicle speed increases. The engine is started when the power request exceeds a sum of the engine-start threshold and the engine-start-threshold offset.

Method for increasing electric operation in hybrid electric vehicles

An example method includes operating an electric machine to produce a torque output and a non-torque output. The method maintains the torque output and intentionally increases the non-torque output to produce a desired condition in an electric vehicle.

Intentionally increasing a non-torque output of an electric machine in an electric vehicle

A method for controlling an engine in a hybrid electric vehicle according to the present disclosure includes, in response to a drive motor being unavailable, commanding an engine power equal to the lesser of a first and a second power. The first power is sufficient to satisfy a driver wheel torque request at the current engine speed, and the second power corresponds to a maximum engine torque available at a target engine speed, where the target engine speed is selected to attain a desired battery state of charge.

Control strategy for a hybrid vehicle with a disabled motor

A vehicle is disclosed that has multiple coolant paths selected by control of a valve. A valve system is configured to direct coolant from an engine to a heat exchanger according to a difference between a temperature associated with the engine and a temperature associated with the heat exchanger. The valve system is also configured to direct coolant from the engine to an electric heater and to, in response to a heat demanded from the heat exchanger being greater than a heat capability of the electric heater, request the engine to run. A method is disclosed for controlling a valve to change from an isolation position in which the valve isolates coolant circulating through an electric heater and the valve from coolant circulating through an engine to a non-isolation position in which the valve directs coolant from the engine to the electric heater.

PHEV heating modes to provide cabin comfort

A control system for a compressor is provided. The control system includes a controller and first and second control portions. The first control portion is configured to assess an actual temperature of an evaporator and a target temperature of the evaporator and to generate a first compressor speed command signal. The second control portion includes a pressure calibration value and is configured to receive a pressure reading of the climate system, to compare the pressure reading to the pressure calibration value and to generate a second compressor speed command signal. The controller device includes data and is configured to receive the first compressor speed command signal and the second compressor speed command signal and to transmit a control signal to the compressor for causing the compressor to operate at a commanded compressor speed based on the first compressor speed command signal, the second compressor speed command signal, and the data.

Method and control system for a compressor that is operable with a climate system

An information display system for a hybrid electric vehicle configured to display one or more reasons an engine is on is provided. The information display system also indicates how close the engine is to turning on due to an engine on reason by displaying a proximity indicator representing a value associated with the engine on reason and a threshold demarcating values which cause the engine to be on.

Vehicle information display and method

A system and method for controlling a powertrain in a vehicle includes controlling a speed of an engine in the vehicle using a first engine speed control when an accelerator pedal position is less than a first predetermined position and a battery discharge limit of a battery in the vehicle is at least a predetermined discharge limit. The speed of the engine is controlled using a second engine speed control different from the first engine speed control when the accelerator pedal position is less than the first predetermined position and the battery discharge limit is less than the predetermined discharge limit.

System and method for controlling a powertrain in a vehicle

Methods and systems are provided for operating an engine in a hybrid vehicle in response to fuel and water dilution of engine lubricating oil. An engine oil dilution counter may be adjusted based on a number of engine hot starts and duration of engine operation above a threshold temperature. In addition, the counter may be adjusted if the engine is started to deplete stale fuel in the fuel tank.

Method and system for oil dilution control

A method for controlling power consumption of a compressor of an automotive vehicle climate system may include identifying an energy source providing energy to power the compressor and selecting an operating parameter of the climate system based on the identified energy source to control power consumption of the compressor.
