A system and method performed by a sensor testing apparatus of a vehicle are provided for determining when certain event conditions are true. The event conditions comprise detecting an occurrence of a predefined event that impacts a sensor of the vehicle. After the predefined event is detected, a test is performed to determine whether the sensor is outputting sensor values within sensor specification values. When the event conditions are true, the method includes testing the sensor relative to a reference to determine when the sensor is operating within reference criteria to produce a positive reference testing result. When the reference testing result is positive, the method directs the vehicle to return to normal operation, and otherwise directs the vehicle to be serviced.

With a method for detecting a contact event on the outer shell of a vehicle, wherein at least one structure-borne sound signal is detected by means of a structure-borne sound sensor, the detected structure-borne sound signal is evaluated by an evaluation device, and wherein the vehicle comprises a number of structure-borne sound sensors, it is provided as essential to the invention that each of the structure-borne sound sensors is associated with an area of the vehicle outer shell via a structure-borne sound conducting link, that an evaluation device is used to ascertain, by which of the structure-borne sound sensors respectively, a structure-borne sound signal has been detected, that conclusions are drawn from the association of the structure-borne sound sensors as to the area of the vehicle outer shell which has been touched, and that conclusions are drawn from the area of the vehicle shell which has been touched, as to the kind of underlying contact.

Provided is an anomaly detection device that acquires a degree of anomaly required for anomaly detection when a feature pattern of time series data changes over time. The anomaly detection device is a device that detects the degree of anomaly in the time series data. The anomaly detection device includes a first acquisition unit, a prediction unit, and an anomaly degree acquisition unit. The first acquisition unit acquires, from a first section that is a partial section of the time series data, a dynamic feature pattern of the first section. The prediction unit predicts data of a second section that is a partial section of the time series data later than the first section by using the feature pattern. The anomaly degree acquisition unit acquires the degree of anomaly based on a difference between the predicted second section data and actual data of the second section.

An impact detection system is disclosed for detecting and identifying an object colliding with a vehicle. The impact detection system comprises a sensor arrangement arranged to measure a characteristic of an impact of the object against the vehicle, a trigger determiner associated with the sensor arrangement for determining whether the characteristic of the 5 impact is greater than a predefined threshold value, and an image capturing device arranged to capture an image of the object. The system is arranged to automatically make the captured image available for inspection in response to the trigger determiner determining that the characteristic of the impact is greater than the predefined threshold value so that the object in the image can be identified substantially in real-time.

A vehicle includes: an audio system, local sensors including a crash sensor, a fuel pump, and processor(s) configured to: (a) select filter(s) based on a determined audio system state; (b) decontaminate present crash sensor data via the filter(s); (c) determine whether to deactivate the fuel pump based on the decontaminated data. The processor(s) are configured to map prior crash sensor data to prior determined audio system states and select the filter(s) by selecting some of the mapped prior crash sensor data.

Disclosed herein are a method and apparatus for sensing as impact on a vehicle based on an acoustic sensor and an acceleration sensor. The method of sensing an impact on a vehicle may include obtaining information related to an impact sound generated in the vehicle of a user and around the vehicle of the user through an acoustic sensor, obtaining information related to an impact applied to the vehicle of the user through an impact detection sensor, and determining an impact sound directly generated in the vehicle of the user based on the information related to the impact sound and the information related to the impact.

A collision accident response system for a vehicle includes: a transparent glass attached to a front surface of the vehicle; a transparent pressure sensor film attached to a rear surface of the transparent glass; and a control unit embedded in the vehicle. The control unit is configured to determine a height and a collision strength of a collision object by a collision pressure detected by the transparent pressure sensor film. As a result, the collision accident response system for a vehicle enables a rapid and accurate response to collision accidents in vehicles equipped with the front glass.

A turret airbag system is provided including a plurality of airbags disposed within the turret to protect an occupant of the turret from injury and/or ejection from the turret. Turret airbags may be configured in padding around a turret access opening, and/or as substantially cylindrical airbags that deploy between the occupant of the turret and a wall or exterior opening of the turret. In some examples, the turret airbag(s) may be integrated with a countermeasure system that deploys explosion countermeasures and activates the turret airbags based on sensor data and multiple thresholds that indicate a collision event, a rollover event and/or an explosion event.
