International Classification:

B60R021/32

US Classification:

280/735000

Abstract:

The present invention involves a method of actuating a deployment of a vehicle airbag during an impact event of a vehicle. The method includes providing a vehicle impact sensor having a plurality of elements, wherein each element is adapted to generate an impact sensor signal having a sensor signal value representing a level of impact. The method further comprising receiving an impact sensor signal from each element during the impact event of the vehicle and summing the sensor signal values of the impact sensor signals to define an aggregate sensor signal value. The method further includes determining a number of impact sensor signals having respective sensor signal values greater than an active element threshold value to define a number of active elements and determining a threshold aggregate sensor signal value based on the number of active elements. The method further includes generating an actuating signal for deploying the airbag, when the aggregate sensor signal value is greater than the threshold aggregate sensor signal value.

International Classification:

F02N 11/08
B60L 58/20

Abstract:

A method for operating a vehicle that includes a DC/DC converter is described. In one example, the method includes adjusting an output voltage of the DC/DC converter after the DC/DC converter is used to crank an engine. The output voltage of the DC/DC converter may be adjusted responsive to a state of charge of an ultra-capacitor.

B60W 20/50
F02N 11/10

Abstract:

A vehicle includes an engine and a controller. The controller may be configured to, responsive to indication of a temperature of a starter-generator exceeding a de-rated threshold, command the engine to start and disable engine automatic shut-off. And the controller may be configured to, responsive to indication of the temperature exceeding a disabled threshold, or the temperature exceeding the de-rated threshold and a traction battery discharge power being less than a threshold, command the engine to start and shed a load.

International Classification:

G01C 21/30
G01S 19/42

Abstract:

A method for localizing a vehicle in a digital map. GPS raw measurement data is retrieved from satellites. A digital map of a region traveled by the vehicle based on the raw measurement data is retrieved from a database. The digital map includes a geographic mapping of a traveled road and registered roadside objects. The registered roadside objects are positionally identified in the digital map by earth-fixed coordinates. Roadside objects are sensed in the region traveled by the vehicle using distance data and bearing angle data. The sensed roadside objects are matched on the digital map. A vehicle position is determined on the traveled road by fusing raw measurement data and sensor measurements of the identified roadside objects. The position of the vehicle is represented as a function of linearizing raw measurement data and the sensor measurement data as derived by a Jacobian matrix and normalized measurements, respectively.

International Classification:

G01S 13/93
G01S 7/41

Abstract:

A system and method for providing target selection and threat assessment for vehicle collision avoidance purposes that employ probability analysis of radar scan returns. The system determines a travel path of a host vehicle and provides a radar signal transmitted from a sensor on the host vehicle. The system receives multiple scan return points from detected objects, processes the scan return points to generate a distribution signal defining a contour of each detected object, and processes the scan return points to provide a position, a translation velocity and an angular velocity of each detected object. The system selects the objects that may enter the travel path of the host vehicle, and makes a threat assessment of those objects by comparing a number of scan return points that indicate that the object may enter the travel path to the number of the scan points that are received for that object.

International Classification:

B60W 30/00

Abstract:

Systems and methods for assisting in coupling a vehicle and a trailer include at least one sensing device disposed on the vehicle. A first coupling is coupled the vehicle and a second coupling is coupled to the trailer. A controller in communication with the at least one sensing device is configured to identify a spatial location of the first coupling. The controller is also configured to determine a spatial location of the second coupling using data from the at least one sensing device. The controller may also calculate a path between the spatial location of the first coupling and the spatial location of the second coupling and convey the path for facilitating movement of the first coupling toward the second coupling.

Abstract:

A method and system for localizing a vehicle in a digital map includes generating GPS coordinates of the vehicle on the traveled road and retrieving from a database a digital map of a region traveled by the vehicle based on the location of the GPS coordinates. The digital map includes a geographic mapping of a traveled road and registered roadside objects. The registered roadside objects are positionally identified in the digital map by longitudinal and lateral coordinates. Roadside objects in the region traveled are sensed by the vehicle. The sensed roadside objects are identified on the digital map. A vehicle position on the traveled road is determined utilizing coordinates of the sensed roadside objects identified in the digital map. The position of the vehicle is localized in the road as a function of the GPS coordinates and the determined vehicle position utilizing the coordinates of the sensed roadside objects.
