摘要: Systems and methods for detecting and reporting vehicle damage events are provided herein. An example method includes detecting any of a key-on or key-off event for a vehicle at a second point in time; in response to detecting the key-on or key-off event, obtaining a current set of images of one or more surfaces of the vehicle using one or more onboard cameras of the vehicle; accessing a baseline set of images for the vehicle obtained at a first point in time that precedes the second point in time; comparing the current set of images to the baseline set of images to determine damage to the one or more surfaces; and presenting a message through a human machine interface of the vehicle that is indicative of the damage.

摘要: Embodiments for diagnosing a humidity sensor are provided. One example method comprises adjusting an engine operating parameter based on humidity of a first gas flow measured by a humidity sensor, and indicating degradation of the humidity sensor if a humidity of a second gas flow measured by the humidity sensor is different than an expected humidity. In this way, degradation of the humidity sensor may be indicated if the humidity of the second gas flow measured by the humidity sensor is different than expected.

摘要: Systems and methods for evaluating whether or not degradation of an engine air intake air filter is present based on a pressure drop across the air filter are presented. In one example, a mean and standard deviation of a pressure drop across an air filter are a basis for indicating whether or not the air filter is degraded. Further, the mean and standard deviation are a basis for estimating a useful life cycle of the air filter.

摘要: Methods and systems are described for monitoring air/fuel imbalance in cylinders of an engine. Engine speed signals are sampled and then run through a notch filter set to the sampling frequency. Based on a first frequency content of the resulting filtered engine speed, cylinder imbalance is detected and addressed.

摘要: An operating mode is determined for a vehicle according to respective control states of each of a plurality of vehicle subsystems that include braking, steering, and propulsion. The operating mode is one of manual control, partial manual control, and no manual control. A route for the vehicle is determined based in part on the operating mode.

摘要: Methods and systems are presented for assessing the presence or absence of engine torque deviation which may indicate air-fuel ratio imbalance between engine cylinders. In one example, the method may include assessing the presence or absence of engine torque variation based on engine torque deviation from a desired engine torque during a deceleration fuel shut-off event.

摘要: Systems and methods for sensing fuel vapor pressure are provided. In one example, a method for a vehicle comprises: during an engine start after the engine has been off for at least a minimum duration, actively controlling fuel pressure in the fuel system to a vapor-liquid volume ratio greater than zero and then recording sensed fuel pressure and temperature in the fuel system. In this way, the vapor pressure of a fuel at a given temperature may be accurately measured during isothermal conditions, thereby improving an estimation of fuel volatility.

摘要: A system of one or more computers can be configured to perform particular operations or actions by virtue of having software, firmware, hardware, or a combination of them installed on the system that in operation causes or cause the system to perform the actions. One general aspect includes a system, including a server computer having a processor and a memory, the memory storing instructions executable by the processor such that the computer is programmed to detect a first vehicle in a first lane adjacent to a second lane and plan a first vehicle trajectory for the first vehicle to be placed in a queue in the first lane and, from the queue, transition from the first lane to the second lane based upon at least one determined characteristic of the first vehicle and a second vehicle trajectory and control the first vehicle based upon the first vehicle trajectory.
