    Abstract: A method for monitoring particulate filter disposed in an exhaust aftertreatment system of an internal combustion engine includes determining, via a differential pressure sensor, a pressure differential across the particulate filter, and determining an initial parameter associated with soot loading on the particulate filter based upon the pressure differential. A first adjustment to the soot loading is determined based upon a passive regeneration effect, a second adjustment to the soot loading is determined based upon an off-engine temperature effect, and a third adjustment to the soot loading is determined based upon occurrence of an interrupted regeneration event. A final parameter associated with soot loading on the particulate filter is determined based upon the initial parameter and the first, second and third adjustments.

  • Publication number: 20180201135
    Abstract: A control element for a motor vehicle provides a palpable response when touched. The control element includes a sensor, a touch-sensitive surface, which when touched causes the sensor to respond. An inert surface surrounds the touch-sensitive surface, which when touched does not cause the sensor to respond. An actuator is disposed between the touch sensitive surface and the inert surface and includes two components that can move relative to each other. One component is connected with the touch-sensitive surface, and the other component is connected with the inert surface. The actuator drives a motion of the touch-sensitive surface relative to the inert surface once a contact has been acquired.

  • Publication number: 20180202380
    Abstract: An LPV/MPC engine control system is disclosed that includes an engine control unit connected to multiple sensors. The engine control unit receives, from the sensors, signals indicative of desired engine torque and engine torque output, and determines, from these signals, optimal engine control commands using a piecewise LPV/MPC routine. This routine includes: determining a nonlinear and a linear system model for the engine assembly, minimizing a control cost function in a receding horizon for the linear system model, determining system responses for the nonlinear and linear system models, determining if a norm of an error function between the system responses is smaller than a calibrated threshold, and if the norm is smaller than the predetermined threshold, applying the linearized system model in a next sampling time for a next receding horizon to determine the optimal control command. Once determined, the optimal control command is output to the engine assembly.

  • Patent number: 10023024
    Abstract: In an example of a method for heating or cooling a vehicle, an application resident on an electronic memory of a mobile communications device is launched. The electronic memory is coupled to a microprocessor. The microprocessor is operatively connected to a mobile device communications platform (MDCP). Preset climate control modes are displayed on a display. A user input identifying a selected preset climate control mode is received at a user interface. In response to receiving the user input, the selected preset climate control mode is transmitted to a vehicle communications platform (VCP). In response to receiving the selected preset climate control mode, a climate control instruction is transmitted by the VCP to a climate control system. In response to receiving the climate control instruction at the control module of the climate control system, the selected preset climate control mode is caused to be implemented in the vehicle.
