A vehicle heating, ventilation, and air conditioning (HVAC) system including a cabin air filter, a sensor for providing a sensor reading, and a controller for determining a feedback signal from the sensor reading, wherein the controller determines a cabin air filter expected blockage level from the feedback signal. The feedback signal relates to a usage modifier of the cabin air filter, wherein the controller at east partially adjusts the estimated usage the cabin air filter from the usage modifier.

Heating, ventilation, and air conditioning system and a method for detecting cabin air filter usage

Methods and systems are provided for improving engine restart operations occurring during a transmission shift in a hybrid vehicle. Engine speed is controller during cranking and run-up to approach a transmission input shaft speed that is based on the future gear of the transmission shift. Engine speed is controlled via adjustments to spark, throttle, and/or fuel, to expedite engine speed reaching the synchronous speed.

Methods and systems for starting an engine

Systems and methods for improving operation of an engine are presented. In one example, a position of a throttle is adjusted along with other actuators to improve engine starting.

Methods and systems for adjusting cylinder air charge

Systems and methods for improving operation of a hybrid vehicle are presented. In one example, an engine is couple to a transmission in response to a transmission upshift to reduce transmission output shaft torque disturbances.

Methods and systems for improving transmission shifting

A vehicle includes a powertrain and a controller. The powertrain includes a powerplant. The controller is programmed to, responsive to a tip-in resulting in a powertrain torque direction reversal and upon obtaining a base value of a desired powertrain lash angle, adjust a powerplant torque schedule. The controller is then subsequently programmed to adjust the desired powertrain lash angle from the base to an adjusted value based on an observed powertrain lash angle that corresponds to a maximum powertrain acceleration during the tip-in.

A method and a system for improving operation of a hybrid vehicle are presented. In one example, an engine exhaust after treatment device is cooled at an opportunistic time. The approach may provide improved cooling for exhaust after treatment devices and it may also improve vehicle emissions.

Method and system for controlling catalyst temperature

A route learning system for a vehicle and a method of using the system is described. The method includes: in response to determining that a current location matches a historical location, retrieving from memory false alert geotag that includes historical path data; and based on determining that a currently-predicted path does not match the historical path, replacing the currently-predicted path with the historical path to mitigate a false warning to a driver of a host vehicle.

Minimizing false collision avoidance warnings

Systems and methods for improving operation of a hybrid vehicle are presented. In one example, driveline operating modes may be manually selected to improve hybrid driveline operation during off road conditions. The approaches may improve vehicle drivability and reduce driveline degradation.

A system and method for controlling backlash in a vehicle powertrain includes the step of controlling a torque request of the powertrain with a first control strategy after an occurrence of a backlash predictor and prior to an occurrence of backlash. The first control strategy is modified when backlash occurs during the first control strategy. The torque request is controlled with the modified first control strategy after another occurrence of a backlash predictor and before another occurrence of backlash.

Adaptive control of backlash in a vehicle powertrain

A system and method for controlling backlash in a vehicle powertrain includes the step of controlling a torque request of the powertrain with a first control strategy after an occurrence of a backlash predictor and before an occurrence of a backlash. Another step may be employed whereby the torque request is controlled with a second control strategy after the first control strategy and before the occurrence of the backlash such that a torque request level is below a highest torque request level obtained during the first control-strategy.

A method and a system for improving operation of a hybrid vehicle are presented. In one example, torque converter impeller torque from beginning to end of transmission shifting is adjusted in response to variable driveline inertia. The approach may improve transmission shifting and reduce driveline torque disturbances.

Method and system for improving hybrid vehicle shifting

Systems and methods for improving operation of a hybrid vehicle are presented. In one example, driveline oscillations are reduced during engine air-fuel ratio modulation. The driveline oscillations may be reduced via adjusting torque of a motor.

Methods and systems for driveline torque control

Systems and methods for improving operation of a hybrid vehicle are presented. In one example, an engine is stopped to a desired position via slipping a driveline disconnect clutch so that engine starting may be improved.
