  • Patent number: 10690103
    Abstract: In some embodiments of the present disclosure, sensors mounted on a vehicle can allow opportunities for coasting to be predicted based on environmental conditions, route planning information, and/or vehicle-to-vehicle or vehicle-to-infrastructure signaling. In some embodiments of the present disclosure, these sensors can also predict a need for power and/or an end of a coast opportunity. These predictions can allow the vehicle to automatically enter a coasting state, and can predictively re-engage the engine and/or powertrain in order to make power available with no delay when desired by the operator.

  • Patent number: 10677180
    Abstract: A first limit requesting process limits a dither control process of fuel injection valves in such a manner that the absolute value of the difference between the air-fuel ratios of the cylinders becomes smaller when the degree of variation of the injection amounts of the fuel injection valves provided for respective cylinders is great than when the degree of variation is small. A second limit requesting process limits the dither control process in such a manner that the absolute value is smaller when the torque fluctuation amount of the internal combustion engine is great than when the torque fluctuation amount is small. The limiting process limits the dither control process in accordance with one of requests generated by the first limit requesting process and the second limit requesting process that causes the absolute value to be smaller than the other.
