The pyrotechnic switch configured irreversibly opens in response to an electronic triggering signal to disconnect an HV battery pack from the HV bus in a first manner. The manual switch is arranged on a low-voltage (LV) bus in series with and between the pyrotechnic switch and an LV power supply. Transition of the manual switch from an open position to a closed position connects the LV power supply to the pyrotechnic switch. This causes the LV power supply to discharge the triggering signal to the pyrotechnic switch. When used aboard a mobile system, an electronic monitoring unit generates the triggering signal in a second manner in response to a threshold impact event.

  • Patent number: 11852089
    Abstract: An engine consumes fuel and air to generate an exhaust gas stream. An exhaust system channels the exhaust gas stream from the engine to a tailpipe. An aftertreatment system is included in the exhaust system and includes a catalyst. A transmission system is coupled with the engine. The transmission system includes a transmission and a torque converter coupled with the transmission through a shaft. A lock is included in the transmission system to selectively prevent rotation of the shaft to increase a load on the engine by the torque converter.

  • Patent number: 11845416
    Abstract: A control system for a vehicle has a powertrain system that includes electric power propulsion system and a second propulsion system, a geographical position sensing system, a geographic map database, and a controller. The controller monitors a geographic location of the vehicle determine the geographic location of the vehicle in relation to a first predefined region and a first user-identified region. The powertrain system is controlled to generate propulsion power employing only the electric power propulsion system when the geographic location of the vehicle is within the first predefined region and when the geographic location of the vehicle is within the first user-identified region. The powertrain system is controlled to generate propulsion power employing the second propulsion system when the geographic location of the vehicle is outside the first predefined region and outside the first user-identified region.

  • Patent number: 11848440
    Abstract: A method of making a negative electrode for an electrochemical cell of a secondary lithium battery. The negative electrode includes composite Li—Si alloy particles dispersed in a polymer binder. The composite Li—Si alloy particles are formed by contacting Li—Si alloy particles with a precursor solution that includes a phosphorus sulfide compound dissolved in an organic solvent to form a lithium thiophosphate solid electrolyte layer over an entire outer surface of each of the Li—Si alloy particles.

  • Patent number: 11845444
    Abstract: A vehicle parameter estimation module is configured to generate a first estimate of a vehicle parameter based on operating conditions of a vehicle measured or estimated at a first time. The vehicle parameter includes at least one of a tire cornering stiffness of the vehicle and an understeer coefficient of the vehicle. The vehicle parameter estimation module is also configured to determine an error value based on the first estimate of the vehicle parameter and values of the vehicle operating conditions measured or estimated at a second time that is later than the first time. The vehicle parameter estimation module is further configured to generate a second estimate of the vehicle parameter based on the first estimate of the vehicle parameter and the error value. A vehicle actuator control module is configured to control an actuator of the vehicle based on the second estimate of the vehicle parameter.
