摘要： The enclosed disclosure relates to hybrid vehicles and systems with an engine, a drivetrain with a clutch and a transmission, an electric machine, and a controller. The controller receives lookahead information within a lookahead window and present state information of the hybrid vehicle. The controller determines a predicted coasting opportunity exceeding a predetermined threshold within the lookahead window and determines a cruise control reference speed, a power split between the engine and the electric machine, and a timing of enabling engine-off coasting during the coasting opportunity. The controller deactivates the engine and disengages the clutch at a start of the coasting opportunity when the engine-off coasting is enabled.

摘要： A method for delaying cylinder reactivation in a vehicle includes identifying, by a controller, a request to exit a cylinder deactivation state. The controller determines if the request is due to a transient condition. If the request is due to the transient condition, the controller analyzes at least one of the transient condition and a condition of the vehicle. The controller determines a first adjustment to the vehicle based on analyzing at least one of the transient condition and the condition of the vehicle. The first adjustment is configured to mitigate the transient condition. The controller implements the first adjustment.

摘要： A cooling system for an electrified vehicle includes a first cooling loop for circulating coolant for cooling at least one of power electronics and a motor/generator of the vehicle. The first coolant loop includes a heat exchanger for exchanging heat with the coolant in the first cooling loop. A second cooling loop is provided for circulating coolant for cooling a battery of the vehicle. The second cooling loop includes a coolant chiller connected to a refrigeration system of the vehicle for exchanging heat in the coolant received from the battery with the refrigeration system of the vehicle.

摘要： A system and method are disclosed for controlling the temperature of an aftertreatment system, the method including interpreting an aftertreatment indicating temperature, determining that an engine fueling requirement is zero, and disengaging the engine from a transmission in response to the aftertreatment indicating temperature falling below a first threshold value and in response to the engine fueling requirement being zero, where the engine and the transmission comprise a portion of a vehicle powertrain. Alternatively, the method may include interpreting an aftertreatment indicating temperature, determining that an engine fueling requirement is zero, and performing a reduced air flow operation through the engine in response to the aftertreatment indicating temperature falling below a first threshold value and in response to the engine fueling requirement being zero.

摘要： A system and method are disclosed for controlling shifting of a vehicle having an automated manual transmission. In the system and method, an amount of fuel being provided to a first grouping of cylinders is reduced, where the first grouping of cylinders are fewer than all of the available cylinders; the first grouping of cylinders are placed in an engine braking mode; a first gear of the vehicle transmission is disengaged; an amount of fuel being provided to a second grouping of cylinders which does not include the first grouping of cylinders is reduced; engine speed is reduced by braking; and a second gear of the transmission is engaged.
