  • Patent number: 10473051
    Abstract: Race car settings (e.g., Formula 1 engine mix settings) are developed for particular racing goals such as faster lap time, better acceleration, less vehicle wear, etc., using pattern templates that are derived from historical racing scenarios. The historical scenarios provide data on racing settings, racing results, and racing conditions such as squad information, equipment information, and environmental information. A cognitive (deep question answering) system can select an initial pattern template based on current racing conditions, and present suggested vehicle settings to the user (driver) using the initial pattern template. The driver can select from different candidate values for various factors, which may lead to the presentation of additional suggestions or the use of additional pattern templates. The final settings map is created based on the employed pattern templates and the driver selections.

The conduit includes a translucent or transparent portion thereof whose longitudinal axis is adapted to be aligned with a force of gravity with a visual scale being disposed on the translucent/transparent portion. The visual scale is indicative of gas flow rates moving through the conduit. A ball disposed in the translucent/transparent portion has an outer diameter that is less than an inner diameter of the translucent/transparent portion. A tube support, coupled to the second end of the conduit, is adapted to hold a gas detection tube wherein the gas flow flowing around the ball is introduced into the gas detection tube from the second end of the conduit.

  • Patent number: 10060368
    Abstract: Methods, devices, estimators, controllers and algorithms are described for estimating the torque profile of an engine and/or for controlling torque applied to a powertrain by one or more devices other than the engine itself to manage the net torque applied by the engine and other device(s) in manners that reduce undesirable NVH. The described approaches are particularly well suitable for use in hybrid vehicles in which the engine is operated in a skip fire or other dynamic firing level modulation manner—however they may be used in a variety of other circumstances as well. In some embodiments, the hybrid vehicle includes a motor/generator that applies the smoothing torque.

  • Patent number: 10036295
    Abstract: A aqueous urea solution supply device for an engine is provided with a tank that stores aqueous urea solution, a valve configured to add the aqueous urea solution to exhaust gas, and a passage configured to supply the aqueous urea solution in the tank to the valve. When a pressure of the aqueous urea solution supplied to the valve is equal to or lower than a predetermined pressure and the amount of the aqueous urea solution in the tank is equal to or smaller than a predetermined threshold, an electronic control unit determines that the aqueous urea solution in an amount required for cooling of the valve cannot be supplied from the tank to the valve and executes a return control for returning the aqueous urea solution in the valve to the tank.

  • Patent number: 10030549
    Abstract: A continuously variable valve timing (CVVT) control device is provided. The CVVT control device includes an engine controlling unit (ECU) configured to output an actual phase angle and a target phase angle of an intake valve or an exhaust valve. The CVVT control device further includes an intellectual motor controller configured to receive the actual phase angle and the target phase angle from the ECU through digital communication in a vehicle. A driving current is generated for adjusting an output torque of a motor based on a phase deviation between the received actual phase angle and target phase angle.

  • Patent number: 10030985
    Abstract: Systems, methods, and apparatuses are described for updating navigational map data. A routing request is received for routing data. A version compatibility matrix may be accessed that corresponds to the routing request. An analysis is performed of a cache database, a main database, and the version compatibility matrix. A number of version conflicts between the cache database and main database are identified based on the analysis. Using these version conflicts, one or more routes based on the routing request are generated.

  • Patent number: 10006383
    Abstract: In a control device and method for an internal combustion engine with a supercharger, a first/second temperature sensor and a first/second air pressure sensor are respectively provided on an upstream/downstream side of a supercharging path from a compressor to a throttle valve. A control portion calculates an inflow air mass to the supercharging path and an outflow air mass from the supercharging path, calculates a throttle upstream air mass in a high operational load state from those air masses, calculates a throttle upstream air mass in a low operational load state from outputs of the first temperature sensor and the first air pressure sensor, selects either one of the throttle upstream air masses depending on an operational load state of the engine, and calculates a throttle upstream pressure based on the upstream air mass selected and a second temperature detected by the second temperature sensor.

  • Patent number: 9989964
    Abstract: A method and a system generate a time-series signal indicative of a variation of the environment in vicinity of the vehicle with respect to a motion of the vehicle and submit the time-series signal to the neural network to produce a reference trajectory as a function of time that satisfies time and spatial constraints on a position of the vehicle. The neural network is trained in to transform time-series signals to reference trajectories of the vehicle. The motion trajectory tracking the reference trajectory while satisfying constraints on the motion of the vehicle is determined and the motion of the vehicle is controlled to follow the motion trajectory.

  • Patent number: 9963011
    Abstract: A dongle that may be plugged into an On-Board Diagnostic (OBD) port of a vehicle and provide notification if a human or animal is left within a parked car. The dongle accesses a first sensor from the vehicle's communication system and a second sensor from within the dongle. If data from the first and second sensors exceeds predetermined threshold values programmed into the dongle's memory, then the dongle sends out a response signal. The response signal may be sent to an owner's cellular phone or to a 911 dispatch center. Additional sensors within the vehicle, or placed within the dongle, may also be used to verify the presence of a human or animal left within the parked vehicle.

  • Patent number: 9952898
    Abstract: A system and method are disclosed for managing the execution of tasks. Each task in a first set of tasks included in a pipeline is queued for parallel execution. The execution of the tasks is monitored by a dispatching engine. When a particular task that specifies a next set of tasks in the pipeline to be executed has completed, the dispatching engine determines whether the next set of tasks can be executed before the remaining tasks in the first set of tasks have completed. When the next set of tasks can be executed before the remaining tasks have completed, the next set of tasks is queued for parallel execution. When the next set of tasks cannot be executed before the remaining tasks have completed, the next set of tasks is queued for parallel execution only after the remaining tasks have completed.
