Devices, systems, and methods are provided for enhanced sensor cleaning validation. A device may determine a baseline performance measurement associated with a clean performance baseline of a sensor. The device may actuate a cleaning mechanism to remove at least a portion of an obstruction deposited on the sensor. The device may determine a first post-clean performance measurement associated with the sensor. The device may determine a degradation measurement between the baseline performance measurement and the first post-clean performance measurement, wherein the degradation measurement indicates an effectiveness of the cleaning mechanism.

A lateral distance sensor diagnosis apparatus cooperating with a lateral distance sensor in a vehicle includes a travel enabled distance acquisition section and a diagnosis test section. The travel enabled distance acquisition section determines whether the vehicle is estimated to have contact with an object detected by the lateral distance sensor, based on a distance detected by the lateral distance sensor and a present steering angle. When determining that the vehicle is estimated to have contact with the detected object, the travel enabled distance acquisition section acquires a travel enabled distance based on a distance detected by the lateral distance sensor. The diagnosis test section determines that the lateral distance sensor fails to operate normally when a movement distance becomes greater than the travel enabled distance under state where the steering angle is an angle causing the vehicle to have contact with an object detected by the lateral distance sensor.

A powertrain system including an engine and transmission is described, and includes a temperature sensor disposed to monitor a hydraulic fluid for the transmission. A method for monitoring the temperature sensor includes monitoring engine operation including engine coolant temperature and monitoring a signal output from the temperature sensor. An indicated temperature slope is determined based upon the signal output from the temperature sensor, and a temperature region associated with the engine coolant temperature is determined. Performance of the temperature sensor is evaluated based upon the indicated temperature slope and minimum and maximum temperature slope thresholds that are associated with the temperature region.

The control method of the unmanned vehicle includes: detecting vibration information and running attitude information of the unmanned vehicle; according to the vibration information, the running attitude information and a running status of the unmanned vehicle, determining a condition of the unmanned vehicle, wherein the running status of the unmanned vehicle includes a stop status and a driving status; and when the condition of the unmanned vehicle is abnormal, controlling the unmanned vehicle according to an abnormal condition coping strategy.

A system and method for the detection of inconsistencies in perception systems of autonomous vehicles is described. The system receives the observations of objects in the surrounding environment from one or more sensors or perception systems of an automated vehicle. At actual time, the system estimates the consistency of the currently observed elements of the perception system according to the previous inputs received. This consistency is decided by calculating the boundaries of possible states of the previously observed elements, based on the received information and on assumptions.

According to some embodiments, described herein is a system and method for handling sensor failures in autonomous driving vehicles (ADV) that is navigating in a world coordination as an absolute coordination system. When the ADV encounters a sensor failure, but still has at least one camera working properly, the sensor failure handling system can switch the ADV from navigating in the world coordination to a local coordination, in which the ADV relies camera-based obstacle detection and lane mark detection to drive safely until human dis-engagement or until the ADV is parked along a road side.

A vehicle, vehicle system and method for increasing at least one of safety and comfort during autonomous driving is provided. The vehicle system includes an autonomous drive arrangement with multiple sensors, a vehicle control arrangement and a positioning system. The vehicle system is configured to determine an estimated probability that at least one sensor will become unavailable, or an estimated time/distance ahead until at least one sensor is determined to become unavailable. The vehicle system is further configured to activate at least one countermeasure based on at least one of the estimated probability, the estimated time and the estimated distance.

A sensor abnormality detection device includes a first sensor that detects a situation of a first region at a periphery of an own vehicle; a second sensor that detects a situation of a second region, which is a region different from the first region and includes an overlapping region that overlaps a part of the first region; a sensor abnormality determination means that determines abnormality of the first sensor and the second sensor; and a collision detection means that detects collision of the own vehicle to an object; wherein the sensor abnormality determination means determines that at least one of the first sensor and the second sensor has abnormality when the first region and the second region do not overlap in the overlapping region after the collision is detected.

An on-vehicle control apparatus (130) switches an operating state of an on-vehicle control system (100) from a regular state to a partially checking state in a case where a cyber-attack has been detected in a part of a plurality of driving control apparatuses (110 and 120). The regular state is an operating state in which autonomous driving is performed by using at least one of the plurality of driving control apparatuses. The partially checking state is an operating state in which the autonomous driving is performed by using at least one of normal driving control apparatuses where the cyber-attack has not been detected, and security of each of the driving control apparatuses where the cyber-attack has been detected is checked.

An oxygen sensor diagnosis control system of a hybrid electric vehicle is provided. The system of a hybrid electric vehicle eliminates an uncertainty of the number of diagnoses of an oxygen sensor and restrains diagnoses of the oxygen sensor in a hybrid electric vehicle. The system of a hybrid electric vehicle includes a hybrid controller operates a vehicle, and determines conversion of an oxygen sensor diagnosis mode based on a result obtained by calculating an oxygen sensor diagnosis index. Additionally, the controller determines whether a condition for diagnosing an oxygen sensor is satisfied when the oxygen sensor diagnosis index decreases to initiate a diagnosis inducing mode or a compulsory diagnosis mode.
