摘要： A system for controlling exhaust noise in a vehicle includes a variable exhaust valve for an exhaust system, and an exhaust valve controller operatively connectable to the variable exhaust valve. The exhaust valve controller is configured to retrieve two or more control conditions, and determine an operational intent based on the two or more control conditions. The exhaust valve controller is configured to generate a control signal based on the operational intent and the two or more control conditions, and transmit the control signal to the variable exhaust valve. The control signal changes an exhaust valve position of the variable exhaust valve. The exhaust valve position is configured to create an exhaust noise response associated with the operational intent.

摘要： A self-calibration method of determining remaining useful life of an internal combustion engine's air filter includes establishing a pressure drop versus mass airflow rate relationship for a clean air filter using pressure drop, mass airflow rate, and temperature data captured at low and elevated engine speeds. The method also includes establishing a maximum clean air filter pressure drop at a preset maximum airflow using the clean filter relationship. The method additionally includes establishing a pressure drop versus mass airflow rate relationship for an in-service air filter using pressure drop, mass airflow rate, and temperature data captured at low and elevated engine speeds. The method also includes determining a maximum in-service air filter pressure drop at the preset maximum airflow using the in-service filter relationship. The method further includes comparing the maximum clean and in-service air filter pressure drops to determine the remaining useful life of the in-service air filter.

摘要： A method for diagnosing an air filter status includes receiving, by a controller, sensor data indicative of a mass air flow rate, an air temperature and an air pressure of an air cleaner assembly including an air filter, determining an air filter life remaining from the sensor data, and receiving data indicative of a vehicle condition. The method also includes determining when a first condition is satisfied and when true, triggering an air filter leakage alert. When the first condition is not satisfied, the controller determines when a second condition is satisfied. When the second condition is satisfied, the controller determines when a third condition is satisfied, and when the third condition is satisfied, triggers an air filter snow intrusion alert. When the second condition is satisfied and the third condition is not satisfied the controller triggers an air filter blockage alert.

摘要： Methods and systems are provided for monitoring an air filter. In one embodiment, a method includes: receiving data indicating a vehicle condition; selectively computing a use life of the air filter based on pressure data and the received data; and selectively generating at least one of a notification signal and a notification message based on the use life.

摘要： A system in a vehicle includes a personal thermal device. The personal thermal device provides heating or cooling to an individual occupant of the vehicle. The system also includes a controller implementing reinforcement learning to control the personal thermal device. The controller obtains states, from one or more sensors, indicating current conditions, to obtain a score that is determined according to the states and that represents a reward used in the reinforcement learning. The controller provides a stochastic policy indicating a probability of taking a particular action to control the personal thermal device based on the score acting as a feedback for feedback control of the personal thermal device using the reinforcement learning.
