  • Patent number: 10690082
    Abstract: Methods and systems are provided for determining whether there is a source of undesired evaporative emissions stemming from a fuel system and/or an evaporative emissions system of a vehicle. In one example, a method includes initiating an evacuation of the fuel system and the evaporative emissions system to conduct an evaporative emissions test diagnostic, in response to a status of a traffic light that the vehicle is approaching. In this way, the fuel system and the evaporative emissions system are evacuated prior to the vehicle coming to a stop, and then a pressure bleed-up portion of the test is conducted while the vehicle is stopped at the traffic light.

  • Patent number: 10576827
    Abstract: A driver controls a switch inserted in a current path between a secondary battery and an inverter that drives a motor. A first abnormality detector instructs the driver to turn off the switch when an abnormality of the secondary battery is detected. A second abnormality detector is disposed in parallel with the first abnormality detector, and instructs the driver to turn off the switch when the abnormality of the secondary battery is detected. The first abnormality detector suspends an instruction to turn off the switch to the driver, even when the abnormality of the secondary battery is detected, in cases where an ECU instructs discharge-stop prohibition of the secondary battery. The second abnormality detector instructs the driver to turn off the switch after a lapse of a certain time from when the abnormality of the secondary battery is detected, regardless of an instruction from the ECU.

    Abstract: A controller of an internal combustion engine receives a request to activate an exhaust brake subsystem and, in response thereto, activates the exhaust braking subsystem. The controller thereafter determines that at least one parameter of the exhaust system, an intake subsystem or both compares unfavorably with at least one threshold. When the at least one parameter compares unfavorably with the at least one threshold, the controller determines that the exhaust braking subsystem has failed. In embodiments, the determination that the at least one parameter compares unfavorably with the at least one threshold comprises a determination that backpressure in the exhaust system is lower than a backpressure threshold and/or a determination that boost pressure in the intake subsystem is higher than a threshold.

  • Patent number: 9213670
    Abstract: A method is provided for graphic visualization of a propulsion energy level gauge relative to a vehicle range meter. A user interface system determines a current range of the vehicle based on a current remaining propulsion energy level of an energy storage device of the vehicle, and determines at least one hypothetical range of the vehicle based on at least one hypothetical level of remaining propulsion energy of the energy storage device. The graphic visualization is provided on a display, where the propulsion energy level gauge conveys the current remaining propulsion energy level and the hypothetical level of remaining propulsion energy, and the vehicle range meter conveys the current vehicle range and the hypothetical vehicle range. In the graphic visualization, the current remaining propulsion energy level is graphically associated with the current vehicle range, and the hypothetical level of remaining propulsion energy is graphically associated with the hypothetical vehicle range.
