  • Patent number: 11624303
    Abstract: Systems and methods provide deceleration fuel cutoff regeneration of a gas particulate filter. A powertrain system includes an exhaust system containing the gas particulate filter, which is configured to collect particulate matter from an exhaust gas stream of the powertrain system. A temperature sensor is configured to monitor a temperature of the gas particulate filter. A loading monitor, such as a sensor and/or a model, is configured to provide a loading input of particulate loading of the gas particulate filter. At least one controller is configured to: determine, by comparing the loading input to stored values, whether the gas particulate filter requires the regeneration; effect a warmup of the gas particulate filter when the determination shows the gas particulate filter requires the regeneration; and initiate the regeneration when a value received from the temperature sensor meets a minimum threshold level.

  • Patent number: 11624617
    Abstract: Systems, methods, and devices are disclosed for synchronizing a map within shared memory for a navigating autonomous vehicle. A map, defined by a geographical area around an autonomous vehicle navigating a route, can be received and stored in shared memory. The shared memory can be a specific physical block of RAM. Concurrent access to the map within the shared memory can be granted to downstream nodes on the autonomous vehicle as the autonomous vehicle navigates the route. This shares the map among many nodes while, at the same time, allowing updates to the map without blocking those nodes at any time.

The network includes a plurality of cell monitoring units (CMUs); each CMU connected to one module for processing data for respective cell groups. The network also includes multiple voltage sensors on each CMU, with each sensor detecting voltage across one cell group. The network additionally includes an electronic controller programmed with an algorithm and in wireless communication with each CMU. The algorithm identifies when electrical power is disconnected from the RESS and directs electrical current through a selected sub-pack after power is restored. The algorithm also interrogates voltage sensors of a particular CMU, detects a change in voltage triggered by the current, and records a cross-reference between the particular CMU and the selected sub-pack when the change in voltage is detected.

  • Patent number: 11624730
    Abstract: A system for determining a trigger amplitude indicating a precursor to a material fracture in a specimen under test includes a microphone converting acoustic emission emitted by the specimen under test into electrical signals. A load is exerted upon the specimen under test and the acoustic emission are emitted when the load causes the specimen under test to undergo deformation prior to the material fracture. A control module is in electrical communication with the microphone and executes instructions to monitor the electrical signals generated by the microphone and filter the electrical signals generated by the microphone. The control module converts the electrical signals generated by the microphone into individual frequency components based on a fast Fourier Transform (FFT). The individual frequency components each include a peak intensity. The control module determines the trigger amplitude based on the peak intensity of the individual frequency components of the FFT.

  • Publication number: 20230106274
    Abstract: An EV can be autonomously charged by using its localization and navigation capabilities. The EV determines its pose in a local area and establishes a connection with a charger coordination system. The EV requests the charger coordination system to find a charging station in the local area based on the EV's pose. The charger coordination system uses the EV's pose to find the charging station. The charger coordination system sends the location of the charging station to the EV. The EV navigates to the charger. The EV further determines its pose relative to the charging station and aligns its charge port with the charger plug of the charging station. The EV may plug itself in or request the charger coordination system to insert the charger plug into the charge port. The alignment and insertion process may be managed by using force sensors on the charger plug or charge port.

  • Publication number: 20230104403
    Abstract: A method for controlling operation of an intelligent vehicle navigation (IVN) system includes a system controller receiving path plan data for a desired route of a vehicle and, using this path plan data, identifying a low/no-connectivity (LNC) area with limited/no wireless service within the desired route. The IVN system retrieves historical trip data containing time durations to cross the LNC area for a statistically significant number of prior trips across the LNC area; the IVN system constructs a probability distribution of these trip durations. The IVN system tracks a time lapse during which no wireless signal is received from the vehicle after output of the vehicle's last wireless signal before entering the LNC area. A driving incident is predicted responsive to the no-signal time lapse exceeding a predefined threshold within the probability distribution. The system controller responds to the predicted driving incident by transmitting an alert to a third-party entity.
