Methods and system are disclosed for vehicle power control. a first high voltage, HV, demand signal is received from a HV device and a first low voltage, LV, demand signal is received from a LV system of the vehicle. The first HV demand signal can be modified based on the first LV demand signal. An input HV supply is received from an e-machine based on the first LV demand signal and modified HV demand signal. An output LV supply is provided from a first DCDC converter to the LV system of the vehicle and an output HV supply is provided from a second DCDC converter to the HV device.

Methods and systems for vehicle power control

A method of providing a heating cycle for an after-treatment system is described. The method comprises initiating a pre-charge cycle of a DCDC converter and determining a temperature of the after-treatment system. In response to determining the temperature of the after-treatment system is below a threshold temperature and the pre-charge is complete, the method further comprises operating a solid-state switch to electrically connect a high voltage power source to a heating element to of the after-treatment system, and heating the after-treatment system with the heating element until the after-treatment system reaches the threshold temperature.

Systems and methods for providing a heating cycle to an after-treatment system of a vehicle

Methods and systems are provided to heat a catalyst of an after-treatment system for a vehicle. The after-treatment system is powered by a battery. An operational parameter of the battery and the driving mode of the vehicle is determined. After receiving an indication that a first operational parameter threshold has been surpassed and a torque demand of the vehicle has been predicted, heat is provided to the catalyst of the after-treatment system based on the predicted torque demand of the vehicle surpassing a second operational parameter threshold.

Systems and methods for controlling an after-treatment system comprising an electronic catalyst

A vehicle includes a power converter that receives power, and has first and second outputs, a low voltage battery that receives power from the power converter via the first output, and a heating element that receives power from the power converter via the second output, and provides heat to a catalyst of an exhaust system. The vehicle also includes a controller that commands the converter to provide power to the heating element via the second output according to a temperature of the catalyst.

This disclosure details thermal management systems for thermally managing electrified vehicle components. An exemplary thermal management system may be configured to direct a coolant through a battery bypass loop that bypasses a traction battery pack based on an amount of heat rejection into the coolant from a water charge air cooler.

Electrified vehicle thermal management systems with battery bypass loops

Methods and system are provided to heat a catalyst of an after-treatment system for a vehicle. The after-treatment system comprises a heating module having a plurality of heating elements. Each of the plurality of heating elements is independently operable to provide thermal energy to the catalyst of the after-treatment system. One or more of the heating elements of the heating module are selectively operated to provide heat to the catalyst based on an operational parameter of the after-treatment system.

Systems and methods for providing heat to a catalyst of an after-treatment system

Methods and system are provided to control engine torque of an engine of a vehicle. The methods comprise determining a drive torque demand on a crankshaft of an engine; determining an accessory torque demand on the crankshaft, the accessory torque demand comprising a first torque demand from a first e-machine and a second torque demand from a second e-machine; determining whether the sum of the drive torque demand and the accessory torque demand is greater than a usable torque capacity output from the engine crankshaft, and increasing a speed of the engine in response to determining that the sum of the drive torque demand and the accessory torque demand is greater than the usable torque capacity output from the engine crankshaft.

Systems and methods for controlling engine torque

Methods and systems are provided for an engine. In one example, a method comprises stopping an engine via a soft-stop method in response to a likelihood of condensate forming being less than or equal to a threshold likelihood. The method further comprises stopping the engine via an exhaust gas evacuation method in response to the likelihood of condensate forming being greater than the threshold likelihood.

Method of operating an internal combustion engine

A vehicle includes an internal combustion engine, an electric machine, and a controller. The electric machine is rotatably coupled to the engine and is configured to deliver electrical power to electrical accessories. The controller is programmed to, in response to a control signal loss between the electric machine and the controller, limit torque output of electric machine to less than a torque threshold that corresponds to the power threshold. The controller is further programmed to, in response an accessory power demand being greater than the power threshold, control the engine to power the electric machine to increase the torque output of electric machine to greater than the torque threshold to meet the accessory power demand.

Hybrid vehicle control system

Methods and systems are provided for an engine. In one example, a method of operating an engine of a vehicle, the vehicle comprising a brake pedal, a clutch pedal and a transmission having a neutral position and at least one in-gear position, comprises starting the engine if either the brake pedal of the vehicle is released or the transmission has been in neutral for a predetermined period of time, and the clutch pedal of the vehicle is depressed concurrently with the transmission being moved out of the neutral position into an in-gear position.

Methods and systems for an engine

Methods and systems for operating an engine with an electrically heated catalyst and an electrically driven compressor are described. In one example, the electrically driven compressor and the electrically heated catalyst are activated before an engine start so that vehicle emissions may be reduced more efficiently at engine starting and thereafter.

System and method for starting an engine

A method of controlling the engine of a vehicle having a stop-in-gear (SIG) stop-start system includes: a control module determining that a brake is being applied, based on an output from a brake sensor, and that a transmission is in an in-gear position, based on an output from a transmission sensor; and, while the brake is applied and the transmission is in an in-gear position, the control module causing the engine to start in response to detecting movement of a clutch pedal towards a released position based on an output from a clutch pedal sensor.

Stop-in-gear auto-start control

Methods and systems are provided for dealing with a change of mind event during an automatic shut-down of an engine in which the speed at which a starter motor used to restart the engine is disengaged is based upon the comparison of current engine speed (N) with a cranking speed limit (S). In one example, during an engine restart while the engine is spinning down, the starter motor may crank the engine to a threshold cranking engine speed adjusted based on a position of the gear.
