A method for operating a powertrain of an autonomous vehicle is described. In one example, the autonomous driver may supply a torque request and a torque or power urgency assessment to a powertrain controller. The powertrain controller may monitor vehicle control system parameters based on the driver demand torque and the torque or power urgency assessment.

Method and system for categorizing powertrain torque requests

A computer includes a processor and a memory storing instructions executable by the processor to receive one or more parameters of a vehicle condition to be monitored, allocate an unreserved parameter identifier to each of the parameters, assign respective memory spaces to each of the allocated unreserved parameter identifiers, and store the parameters in the memory spaces.

Vehicle component fault detection

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.

EGR system diagnostics

Systems and methods for waking a controller from a sleep mode are described. In one example, the controller may be woke in response to an estimated amount of time that it will take for a temperature in an evaporative emissions system to be within a threshold temperature of ambient temperature.

System and method for a vehicle diagnostic wakeup

A method and a system for diagnosing positive crankcase ventilation (PCV) systems are disclosed. In one example, the method diagnoses a PCV system based on a pressure that may be observed during engine cranking. In another example, the PCV system is diagnosed during vehicle driving conditions after the engine exits cranking.

System and method for diagnosing a crankcase ventilation system

Methods and systems are provided for a coolant system. In one example, a method may include diagnosing a condition of a pump of the coolant system based on a temperature change of coolant. The diagnostic may determine if the pump is stuck on or off.

Methods and systems for coolant system diagnostics

A system comprises a processor that is programmed to define a plurality of vehicle groups based on vehicle specification data and define a plurality of sub-groups for each of the vehicle groups based on environmental data and sensor data received from each of a plurality of vehicles. The processor is programmed to adjust fuel tank leak detection classifiers for the sub-groups based on ground truth data. The ground truth data include, for each of the plurality of vehicles, a leak detection status and a leak test result.

Adaptive diagnostic parametrization

Methods and systems are provided for a high-pressure exhaust gas recirculation system. In one example, the high-pressure exhaust gas recirculation system comprises pressure seconds arranged on different sides of a valve. The pressure sensors are used to regulate exhaust-gas recirculate flow without a fixed orifice delta pressure sensor.

Methods and systems for an exhaust gas recirculation system

Methods and systems are provided for updating an in-use monitoring performance (IUMP) based on operation of an auxiliary device. In one example, a method may include using an engine model to estimate a duration in which a diagnostic routine is not completed due to operation of an auxiliary device driven by an engine and selectively updating the IUMP ratio based on a comparison of the duration to a minimum time duration needed for completion of the diagnostic routine.

Methods and systems for in-use monitor performance

Methods and systems are provided for a vehicle coolant circuit. In one example, the coolant circuit includes a heater core isolation valve (HCIV) where a status of the HCIV may be diagnosed by intrusively activating a positive temperature coefficient heater in a cooling loop in which the HCIV is arranged. A response of coolant temperature to heater activation may be used to determine a position of the HCIV.

Method for detecting heater core isolation valve status

Methods and systems are provided for monitoring a status of a heater core isolation valve (HCIV) housing in an engine coolant circuit including a first coolant loop and a second coolant loop. In one example, a method may include indicating degradation of the HCIV based on a difference between a first coolant loop temperature and a second coolant loop temperature upon activation of coolant system pumps and deactivation of a positive temperature coefficient (PTC) heater housed in the cabin heating loop.

Methods and systems are provided for assessing a state of a vent hose that fluidically couples a crankcase of an engine to an engine air intake system. In one example, a method may include sealing the crankcase from the vent hose, initiating cranking of the engine, monitoring a series of pressure pulsations during a monitoring window duration via a pressure sensor positioned between a crankcase oil separator and the vent hose, and indicating a presence of degradation associated with the vent hose based on the series of pressure pulsations and the monitoring window duration. In this way, diagnosis of a state of the vent hose may be reliably assessed without crankcase pressures confounding pressure measurements as recorded via the pressure sensor.

Systems and methods for crankcase system diagnostics

Methods and systems are provided for diagnosing a humidity sensor in an engine. In one example, a method may include heating intake air entering an intake passage of an engine using heat recirculated from an exhaust system of the engine. A response of the humidity sensor to the heating of the intake air may be used to assess an integrity of the humidity sensor.

Systems and methods for relative humidity sensor diagnostics

Methods and systems are provided for a high-pressure exhaust gas recirculation system. In one example, the high-pressure exhaust gas recirculation system comprises pressure sensors arranged on different sides of an EGR valve. Feedback from the pressure sensors are used to diagnose a EGR valve position sensor.

Methods and systems for EGR system

Methods and systems are provided for monitoring a crankcase ventilation system. In one example, a method may include diagnosing a breach in a crankcase vent tube based on a regression of measurements of pressure in the crankcase vent tube. The regression allows the pressure measurements to be extended across an entire range of operating air flows and the breach may be identified by comparing the regressed pressure measurements to expected crankcase vent tube pressures.
