    摘要: Onboard engine control for vehicles is disclosed herein. An example method includes determining a moving average of duty cycle periods for a power component of a vehicle for recent power load events, each of the duty cycle periods having both on-time portions and off-time portions; and when the on-time portions of the moving average are above a predetermined percentage, an engine of the vehicle remains in an on-state condition, further wherein when a current off-time period of the power component exceeds a value equal to a predetermined multiplier applied to the off-time portions, the engine is placed in an off-state condition.

    摘要: Upon identifying an authorized user approaching a vehicle, vehicle locks are controlled to permit the authorized user to access an authorized area based on a user authorization. Permitted vehicle features within the authorized area for the authorized user are identified based on the user authorization. Upon receiving a user input selecting one permitted vehicle feature, the selected permitted vehicle feature is actuated based on determining that a state of charge of a battery is above a charge threshold. Upon determining that the state of charge of the battery decreases below the charge threshold, actuation of the selected permitted vehicle feature is stopped. Then an engine is controlled to charge the battery based on the user authorization.

    摘要: A vehicle includes a liftgate system with a vertically-opening liftgate and a power actuator responsive to a user opening command for opening the liftgate to a variable opening height. The vehicle has an active sensor adapted to detect objects and their respective distances within a detection zone and a camera adapted to capture a search image with a field-of-view showing objects in the detection zone. In response to the user opening command, a controller 1) performs facial recognition on the search image to detect image locations containing a face of each respective person visible in the search image, 2) identifies distances for each respective person according to coincidence with the detected objects, 3) determines a user height according to the respective image location and distance of at least one respective person visible in the search image, and 4) sets the variable opening height in response to the user height.

    摘要: An AC inverter in a vehicle operates using a 24V input when a vehicle powertrain is in a parked/idling state. A first 12V battery is connected with a first bus segment. A second 12V battery is connected with a second bus segment. A switch module selectably interconnects the first and second bus segments. In a nominal 12V state, the batteries are connected in parallel from the bus segments to ground. In a dual voltage state, the batteries are connected in series so the first bus segment is at 12V and the second bus segment is at 24V. A first alternator driven by the powertrain provides a regulated voltage to the second bus segment, wherein the regulated voltage corresponds to 12V when the switch module is in the nominal state and corresponds to 24V when the switch module is in the dual voltage state.

    摘要: A vehicle assembly includes, among other things, a camouflaging cover configured to be placed over an exterior surface of a vehicle to conceal at least a portion of the vehicle, and a camouflaging lighting assembly integrated with the camouflaging cover. A vehicle lighting assembly includes, among other things, at least one light emitting device, a circuit board operatively connected to the at least one light emitting device, a housing having a first material composition, and at least one lens having a second material composition. The lens is more transparent than the housing. The first and second material compositions each includes a thermally conductive additive. A vehicle lighting method includes, among other things, concealing at least a portion of a vehicle with a camouflaging cover, and positioning a camouflaging lighting device over a light of the vehicle. The camouflaging lighting device is integrated with the camouflaging cover.

    摘要: A method for maximizing the availability of start-stop operations within a microhybrid vehicle includes determining the electric current drawn by a set of electrical components of the vehicle, from the vehicle's battery. The internal resistance of the vehicle's battery, and the resistance of a starter motor loop circuit coupled to the engine of the vehicle are dynamically calculated. The closed-circuit voltage of the battery is predicted, using the internal resistance of the battery, the resistance of the starter motor loop circuit, and the current drawn by the set of electrical components of the vehicle. The start-stop operation is carried out if the closed-circuit voltage of the battery is predicted to be above a pre-determined minimum value.
