摘要： A processor, responsive to detecting a controller is drawing power from a battery to perform a task when a vehicle is parked and detecting a parameter indicative of a likelihood that the controller will complete the task within a predefined time period has a value less than a threshold value, generates a message for a user requesting whether the controller should be shut down without completing the task.

摘要： Methods and systems are provided for an exhaust gas recirculation (EGR) system. In one example, a method includes determining a present EGR valve offset and an historical EGR valve offset and comparing the present EGR valve offset and the historical EGR valve offset to determine a presence of an EGR leak.

摘要： Methods and systems are provided for diagnostics of exhaust gas recirculation (EGR) components including an EGR pressure sensor. In one example, a method may include comparing a current relationship between an output of the EGR pressure sensor and a manifold air pressure (MAP) and a pre-calibrated relation between the output of the EGR pressure sensor and the MAP to detect degradation of the EGR pressure sensor.

摘要： Methods and systems are provided for reducing contactor freezing. In one example, a system may include a contactor comprising a set of conductors and a phase change material. The phase change material is coupled to a first conductor of the set of conductors and is not positioned between the set of conductors.

摘要： Methods and systems are provided for adjusting a position of an exhaust valve that regulates engine exhaust noise. In one example, the position of the exhaust valve is adjusted according to a distance between a first vehicle and a second vehicle. The exhaust valve may be adjusted to reduce an exhaust noise level when the distance between the first vehicle and the second vehicle is less than a threshold distance.

摘要： Methods and systems are provided for opportunistically mitigating an intermittent degradation of an active exhaust valve. In one example, a method may include differentiating between a permanent degradation of the active exhaust valve and an intermittent degradation of the active exhaust valve and adjusting actuation of the valve based on a vehicle operating condition and a road condition to mitigate the intermittent degradation.

摘要： Methods and systems are provided for EGR valve diagnostic. In one example, a method includes providing a correction to a position of the EGR valve to compensate for an altitude of the vehicle. The compensation is based on a comparison of a pressure ratio to a curve rationalized with a barometric pressure.

摘要： A method for operating a vehicle that includes a passenger is described. In one example, the method adjusts vehicle suspension and exhaust system sound in response to characteristics of the passenger that are monitored via a camera and a microphone. The method may operate the vehicle suspension and exhaust system in a way that sooths the passenger.
