A method checks a functionality of a solenoid valve for a brake system in a motor vehicle. The solenoid valve includes an armature and a coil. The armature, on actuation of the solenoid valve, is moved by a magnetic field of the coil, reducing an air gap of the solenoid valve defined by a position of the armature. The method includes measuring an electric current during the actuation of the solenoid valve, analysing a characteristic of the electric current during the actuation of the solenoid valve, and assessing the functionality of the solenoid valve based on the analysis of the characteristic of the electric current.

Provided are a signal processing system and a signal processing method for sensors of a vehicle. More particularly, the signal processing system includes: a vehicle sensor unit 100 including the plurality of sensors previously provided in the vehicle and transmitting sensing information acquired through the sensors; an arithmetic and control unit 200 receiving sensing information from the vehicle sensor unit 100, and comparing and analyzing the received sensing information to discriminate only normal sensing information from the sensing information and set and transmit the normal sensing information as output information; and a display unit 300 including a plurality of displays previously provided in the vehicle, transmitting the output information received from the arithmetic and control unit 200 to the matched display of the plurality of displays, and outputting the output information through the matched display of the plurality of displays.

A pedestrian terminal device receives pedestrian information transmitted from another pedestrian terminal device which is present in the vicinity of the pedestrian terminal device. A location of the pedestrian terminal device is acquired, and it is determined whether or not a pedestrian who carries the pedestrian terminal device is located inside a pedestrian group based on the location of the pedestrian terminal device and a location of the other pedestrian terminal device included in the pedestrian information. When the pedestrian is located inside the pedestrian group, pedestrian-vehicle communication is stopped.

Methods, systems, and computer program products for generating estimates of failure risk for a vehicular component are provided herein. A method includes splitting an input time series pertaining to a vehicular component across a fleet of multiple vehicles into multiple sub-time series, wherein each sub-time series comprises multiple data points of the input time series that correspond to measurements derived from the vehicular component; determining a weight applied to each of the sub-time series based on a pre-determined weight associated with the input time series; applying a failure or non-failure classification label to each of the sub-time series and the input time series; calculating a performance measure for the input time series; determining an updated weight associated with the input time series; and generating an estimate of failure risk for the vehicular component based on the classification label applied to each input time series and the updated weight.

Systems of an electrical vehicle and the operations thereof are provided that use identifiers and sensed power source parameters to determine whether a rule, such as a warranty or licensing requirement, has been violated.

A remotely extendable motivator apparatus includes a handheld unit operatively coupled to a distal unit. Manual compression of an actuator disposed on the handheld unit effectuates extension of an extendable member forwardly from an anterior member disposed on the distal unit. Distal unit may be positioned in a footwell of an automobile to effectuate depression of a targeted pedal while a user performs observational diagnostics on the automobile without the assistance of another person.

A diagnostic device, in accordance with a marker condition setting function, sets marker conditions for adding markers to collected data. Next, the collected data are read out from a data collecting device. Next, in accordance with a marking function, markers are added to the collected data at points in time when the set marker conditions are satisfied. Then, in accordance with a file creation function, with reference to the markers of the collected data, the collected data that took place within a predetermined time range before and after the markers is extracted, and the collected data is stored in individual analysis files.

A device for testing vehicle airbags includes a pusher plate that has first mounting holes and second mounting holes, a first pin received in one of the first mounting holes, a second pin received in one of the second mounting holes, a first magnet coupled to the pusher plate, and a second magnet coupled to the pusher plate. The device includes a first mass received on the first pin and secured to the pusher plate by the first magnets prior to and during acceleration of the pusher plate, and a second mass separate from the first mass and received on the second pin, the second mass secured to the pusher plate by the second magnets. Deceleration of the pusher plate causes the first mass and the second mass to release from the pusher plate. The device includes an accelerator coupled to the pusher plate and a vehicle airbag deployment device.
