A method for identifying potential component manufacturing issues identifying a first set of calibration values corresponding to a first component and flashing a controller associated with the first component with the first set of calibration values. The method also includes performing at least one diagnostic test on the first component and, in response to receiving at least one diagnostic flag resulting from the at least one diagnostic test, determining whether the at least one diagnostic flag includes a false positive response. The method also includes, in response to a determination that the at least one diagnostic flag includes a false positive response, selectively adjusting at least one calibration value of the first set of calibration values and, in response to a determination that the at least one diagnostic flag does not include a false positive response, flashing the controller associated with the first component with a first set of production calibration values.

A system and method for performing a diagnostic on a hydraulic system in a vehicle while the vehicle is at a standstill. The method includes, by means of an electronic processor, moving a plunger at a constant rate, determining a position of the plunger, receiving a pressure of the hydraulic system from a pressure sensor, comparing the determined position and the measured pressure to a position versus pressure graph, and sending a diagnostic to a diagnostic indicator.

A sensor error correcting apparatus is provided with: a roll angle estimator configured to estimate a roll angle on the basis of a yaw rate of a moving body, a wheel speed, and lateral acceleration; a converter configured to convert the yaw rate to a horizontal yaw rate, on the basis of an estimated roll angle; and a zero point corrector configured to compare an azimuth change amount obtained by integrating the horizontal yaw rate in a turning period, which is from a start of turning of the moving body to an end of the turning, with an azimuth change amount of the velocity vector in the turning period, and configured to correct the measured lateral acceleration.

A system for testing functionalities of a vehicle while driving the vehicle having a message-based bus network topology comprises a software server configured to be connected to the bus and to take vehicle sub-system information therefrom and interpret it as output from a timed automaton. The system also comprises at least one client in the form of an executable test script written in a programming language and configured to from the server subscribe specific vehicle sub-system information to be used by a test assessment oracle of the test script for assessing a particular function or sub-function of the vehicle.

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.

A vehicle has one or more accelerometers for detecting acceleration of a chassis component. One or more separate sensors are also provided in the vehicle. A controller is programmed to receive a signal indicating acceleration from the one or more accelerometers, wherein the acceleration is between a lower threshold that indicates normal vehicle operation and an upper threshold which would otherwise set off restraint devices, such as airbags for example. When the acceleration is between the thresholds, a potential-chassis-damage signal can be locally created or sent. The controller then validates the potential-chassis-damage signal based on the signals received from the separate sensors. Upon validation, the controller outputs a message to a display, such as a display screen inside the vehicle or an OBD diagnostic tool, warning a user of potential-chassis damage.

In a method for detecting damage to a component of an aircraft, having an unpressurized first area and a pressurized second area, at least one theoretical pressure parameter, characteristic of a theoretical pressure in the unpressurized first area, a theoretical pressure in the pressurized second area or a theoretical pressure difference between the unpressurized first area and the pressurized second area, is determined. At least one actual pressure parameter, characteristic of an actual pressure in the unpressurized first area, an actual pressure in the pressurized second area or an actual pressure difference between the unpressurized first area and the pressurized second area, is recorded. The theoretical pressure parameter is compared with the actual pressure parameter. Damage to a component of the aircraft causing a compression of the unpressurized first area is detected when a difference between the theoretical pressure parameter and the actual pressure parameter exceeds a threshold value.

An OBD module for communicating with a vehicle radio/infotainment system. The OBD module includes a controller, a data bus interface that is configured to draw power from and electronically communicate with a vehicle OBD-II data port and a digital interface connector. The OBD module can be formed from two separate components, including a transceiver module and an interface module, that are in communication with each other. The transceiver module can be located remotely from the interface module. The OBD module can include a graphic equalizer to enhance the sound quality of the input source. The OBD module can also be configured to interrupt playback to play a substitute message as is desired.
