Abstract: A computer, including a processor and a memory, the memory including instructions to be executed by the processor to train a generative adversarial network (GAN) to reconstruct a missing portion of an image by determining a reconstructed portion of the image based on data from portions of the image surrounding the missing portion and compare an acquired image with the reconstructed portion of the image to determine a damaged portion. The instructions further include instructions to determine estimated damage based on the damaged portion.

Abstract: Methods and systems are provided for diagnosing a shock absorber coupled to a vehicle tire. In one example, a sensor of a tire pressure measurement system coupled inside a tire is used to measure a tire pressure as well as an oscillatory behavior of the tire. A state of health of a shock absorber coupled to the tire is estimated based on the oscillatory behavior.

Abstract: An emissions control system for a vehicle configured to travel on a road is provided. In one example, a forced modulation of a UEGO is provided when output of a HEGO sensor is unavailable.

Abstract: A system for a vehicle traveling on the road is shown. The system includes a first cylinder; a second cylinder; a linear exhaust gas sensor coupled exclusively to said first cylinder; a switching exhaust gas sensor coupled exclusively to said second cylinder; and a controller configured to perform a decontamination cycle where one of said first cylinder and second cylinder produces a reductant rich exhaust and the other of said first and said second cylinder produces an oxygen rich exhaust, where an air-fuel ratio of one of said first and second cylinder is adjusted in response to said linear sensor.

Abstract: An emissions control system for a vehicle configured to travel on a road is provided. The system typically includes a catalyst coupled to the exhaust gas path; a linear universal exhaust gas oxygen (UEGO) sensor coupled to the exhaust gas path upstream of the catalyst and configured to measure oxygen content in exhaust gas from the engine upstream of the catalyst; a heated exhaust gas oxygen (HEGO) sensor positioned adjacent the catalyst and configured to measure oxygen content in exhaust gas from the engine; a temperature sensor coupled to the engine; and a controller coupled to the engine and configured to receive an input signal from the HEGO sensor that is indicative of oxygen content in the exhaust gas, to receive an input signal from the temperature sensor that is indicative of engine temperature, to adjust the HEGO sensor input signal based on the input signal from the temperature sensor, and to control the air-fuel ratio based on the adjusted HEGO sensor input during engine warm up.

The system further typically includes a controller coupled to the engine and configured to, during a warm up period of the catalyst during which input from the HEGO sensor is unavailable, adjust an engine air-fuel ratio of the engine in response to the input from the linear exhaust gas oxygen sensor, and further configured to provide modulation of said air-fuel ratio during the warm up period so that the air-fuel ratio of the engine oscillates about a selected target ratio.

Abstract: A system and method of operating a vehicle powertrain that employs active control to reduce NVH, particularly during idle. The method includes selectively operating the powertrain in at least a non-idle condition and an idle condition; receiving vibration signals from a sensor disposed on an internal combustion engine; controlling spark timing of the internal combustion engine based on vibration signals received from the sensor; and during the idle condition, modifying a speed and/or a load of the internal combustion engine based on vibration signals received from the sensor.
