Abstract: A method includes determining a distance remaining from a current vehicle location to a traffic control signal and determining a recommended speed over the distance remaining that will cause the vehicle to reach the traffic control signal at a time when the signal permits travel. The method includes obtaining traffic data indicating the presence of traffic between the present location and the signal and predicting movement patterns and timing of traffic indicated by the traffic data, and adjusting the recommended speed to accommodate the predicted movement patterns and timing of traffic, to preserve vehicle momentum in light of changes to travel required by the predicted movement patterns and timing. The method additionally includes displaying the recommended speed and continuing at least the determining the distance, determining the recommended speed and displaying the recommended speed until the vehicle either stops or reaches the traffic control signal.

Abstract: Methods and systems are provided for warming vehicle tires prior to a vehicle launch event. In one example, a method may include, in response to an initiation of a burn out event while locking non-driven wheel brakes, adjusting a spinning of driven wheels based on vehicle performance parameters measured during a previous vehicle launch. In this way, a vehicle controller may control the tire warming to increase tire traction while reducing tire wear.

Abstract: Methods and systems for operating an engine that includes adjustable poppet valve timing and an exhaust gas recirculation valve are described. In one example, the exhaust gas recirculation valve is opened and the timing of the poppet valves is retarded so that an amount of fresh air that is pumped by the engine to an after treatment device may be reduced.

Abstract: A system includes a processor configured to receive a request from a host vehicle for video relating to a location specified in the request. The processor is also configured to determine whether a candidate vehicle receiving the request can provide the request video when the request is received. The processor is further configured to relay the request to a transceiver in wireless communication with the candidate vehicle, if the candidate vehicle cannot provide the requested video, otherwise record and transmit the requested video.

Abstract: Systems and methods for starting an engine of a hybrid vehicle are described. In one example, the method uses the engine to generate larger amounts of thermal energy while the engine is rotated under power of an electric machine. The systems and methods described herein may be applied to series and parallel hybrid vehicles.

Abstract: Systems and methods for connected vehicle and mobile device communications are provided herein. An example method includes determining a distracted condition for at least one of a driver or a pedestrian by evaluating actions occurring within in a vehicle of the driver or on a mobile device of the pedestrian; determining a distraction level for either the driver or the pedestrian based on the actions occurring within in the vehicle or on the mobile device; and providing an alert message to the mobile device or a human machine interface of the vehicle based on the distraction level, the alert message warning of a distracted condition of the pedestrian or the driver.

Abstract: Systems and methods are provided for controlling deceleration fuel shut off (DFSO) in response to an external object or location, such as a target vehicle. In one example, a method may include, while operating an engine in DFSO, determining a rate of change of a range to the target vehicle, and commanding an exit from the DFSO based on the range rate of change. By exiting the DFSO based on the range rate of change, torque lash experienced by a driver may be correspondingly reduced as compared to exiting the DFSO based upon, for example, one or more powertrain operating conditions.

Abstract: A computer includes a processor and a memory, the memory storing instructions executable by the processor to, in a host vehicle, determine a threat number for a first target vehicle based on data received from the first target vehicle indicating at least one of a position, speed, or route history of the first target vehicle, identify a second target vehicle based on data collected with one or more host vehicle sensors when the threat number of the first target vehicle exceeds a threshold, determine that the first target vehicle and the second target vehicle are not a same vehicle, and, then, upon determining that the first target vehicle and the second target vehicle are not the same vehicle and that at least one of (a) a barrier is detected between the host vehicle and the first target vehicle or (b) that a threat number of the second target vehicle exceeds a second threshold, suppress a collision avoidance action.

Abstract: A communication system for a vehicle includes an accelerometer, and a controller electrically coupled to the accelerometer and configured to respond to a signal indicative of an accident of the vehicle. The controller's response to the signal includes activating an emergency mode, requesting biometric data of occupants of the vehicle, and transmitting data identifying the vehicle, a location of the vehicle and a time of activation, and biometric data.

Abstract: A vehicle includes a controller, programmed to, send a vehicle status report reflecting current status of the vehicle to a server; responsive to receiving a connection message from the server indicative of a predicted data transaction, wirelessly connect to a fleet vehicle using the connection message; and transmit a data block defined in the connection message to the fleet vehicle.

Abstract: Methods and systems are provided for estimating ethanol content in fuel, water content in fuel, and an age of the fuel in a vehicle engine. In one example, a method may include estimating fuel ethanol content, water content, or fuel age based on fuel rail temperature, and two or more of a resonant frequency (f) of pressure pulsations, a change in fuel rail pressure (?p), and a damping coefficient (?) of pressure pulsations in the fuel rail as estimated after a fuel injection or a pump stroke. One or more engine operating parameters may be adjusted based on the estimated fuel ethanol content, water content, and fuel age.

Abstract: Methods and systems are provided for calibrating an effective area associated with an exhaust gas recirculation valve and/or a variable orifice associated with the exhaust gas recirculation valve. In one example, a method may include attaining a first steady-state intake pressure with the exhaust gas recirculation valve closed, determining a second steady-state intake pressure and a differential pressure across the variable orifice with the exhaust gas recirculation valve open, and estimating the variable orifice effective area based on the second steady-state intake pressure and the differential pressure. In this way, a calibration table may be updated for an exhaust gas recirculation control apparatus that includes an exhaust gas recirculation valve and a variable orifice, such that an actual amount of recirculated exhaust gas reflects a commanded amount.
