Abstract: A powered latch system for motor vehicles includes at least one powered latch that can be controlled based, at least in part, on vehicle operating conditions. The system may be configured to control unlatching of the vehicle doors utilizing data relating to the vehicle speed and/or the existence of a crash event. The powered latch system can be configured as required for various vehicles, and to accommodate specific operating requirements with respect to child locks in various geographic jurisdictions.

Abstract: Systems and methods described herein provide for assigning classifications to signals and corresponding messages for prioritization and transmission across a vehicle CAN bus. The assigned classifications are used to select authentication keys specific to each classification of message. Nodes of the CAN bus can include different sets of keys based on the classifications of messages handled at the nodes. Keys are distributed and localized to reduce any potential impact on critical functions of the vehicle system that may result from compromise of an authentication key.

Abstract: A latch system for vehicle doors includes a powered latch including a powered actuator that is configured to unlatch the powered latch. An interior unlatch input feature such as an unlatch switch can be actuated by a user to provide an unlatch request. The system may include a controller that is operably connected to the powered actuator of the powered latch. The controller is configured such that it does not unlatch the powered latch if a vehicle speed is greater than a predefined value unless the interior latch feature is actuated at least two times according to predefined criteria.

Abstract: Authorization of a user device is suspended based on determining, for a first predetermined time, a distance between the user device and a vehicle is greater than a threshold distance. Then a user input specifying a vehicle parameter is requested. Upon receiving the user input, the user input is validated based on the user input matching a stored vehicle parameter. The user device is deauthorized based on a) failing to receive a valid user input within a second predetermined time, or b) receiving a number of invalid user inputs equal to a threshold number.

Abstract: Systems and methods described herein provide for assigning classifications to signals and corresponding messages for prioritization and transmission across a vehicle CAN bus. The assigned classifications are used to prioritize messages, signals, and nodes of the vehicle CAN bus. The classifications are used to prioritize critical messages and high priority messages that control operations of the vehicle system.

Abstract: The present disclosure relates to a system that allows engagement of an electronic plug-in device (EPID) with an on-board diagnostic II (OBD-II) port of a vehicle. The EPID includes an accelerometer and a processor. The accelerometer detects vibrations associated with engine operation. The processor, in communication with the accelerometer, executes instructions to receive an input waveform from the accelerometer. The processor may determine whether the input waveform from the accelerometer is associated with the engine operation. The processor may transition the EPID from a sleep state to a wake state if the input waveform is detected to be associated with the engine operation. In contrast, the processor may transition the EPID from the wake state to the sleep state when the input waveform is not associated with the engine operation.

Abstract: A Phone-as-a-Key (PaaK) system includes a pre-processor, a secure processor disposed in communication with the pre-processor, a cache memory associated with the pre-processor and the secure processor, and a memory for storing executable instructions. The pre-processor and the secured processor are configured to perform steps that can mitigate delay caused by mobile device authentication. For example, the pre-processor authenticates an authentication message associated with a mobile device used as a key for the vehicle, and stores the message in the cache memory. The pre-processor receives a door latch actuation signal, and initializes the secure processor in response. The pre-processor then provides access to the vehicle based on the secure processor initialization instruction, and the authentication message stored in the cache memory.

Abstract: A device for controlling a restricted mode of a vehicle is provided. The device includes a controller that is configured to receive an input indicative of a request to change a vehicle state from a fully operational mode to a restricted mode and to transmit a first control signal indicative of a request to limit at least one of vehicle speed and vehicle acceleration. The controller is further configured to monitor a distance traveled by a driver when the vehicle is in the restricted mode and to compare the distance traveled to a predetermined distance limit. The controller is further configured to transmit a second control signal to remove the request to limit the at least one of the vehicle speed and the vehicle acceleration in response to determining that the distance traveled exceeds the predetermined distance limit.

Abstract: An access assessment tool is described for providing a technical solution for selectively controlling access to restricted information and/or implementation of restricted functionalities based on a current vehicle mode and/or validated credentials. The access assessment tool described herein controls the validation of a user or diagnostic tool requesting access to restricted information or implementation of a restricted function before allowing access to the restricted information or allowing implementation of the restricted function.

Abstract: A body controller may monitor a vehicle bus for diagnostic requests received from a scan device connected to a diagnostic port when a vehicle perimeter alarm of a body controller is armed. The body controller may reset a predetermined lockout timeout responsive to receipt of a session request from the scan device. Upon expiration of the lockout timeout, the body controller may request to establish the session with the body controller from the scan device for a predetermined access timeout. When the session is established, the body controller may allow a user to program entry devices to the body controller and/or download software updates to the body controller.
