Abstract: A disclosed method of automatically stopping and restarting a vehicle engine determines if one or more stop/start enablement condition has been met. If the stop/start enablement condition or conditions have been met, the method initiates an engine shutdown. If a restart request is made before the engine reaches a predetermined threshold speed, then a first restart sequence is initiated. If a restart request is made when the engine speed is less than the predetermined threshold speed but still greater than 0, then a second restart sequence is initiated.

Abstract: Systems and methods for providing charge to an energy storage system of a vehicle are provided. The method may include receiving, by a vehicle control system, an indication that a vehicle is coasting, slowing, and/or braking. Based on the received indication, engaging, by the vehicle control system, an electric motor coupled to an internal combustion engine to generate electric charge and provide the generated electric charge to the energy storage system, and while engaging the electric motor to generate electric charge, deactivating, by the vehicle control system, a cylinder of the internal combustion engine by maintaining an inlet valve of the cylinder and an exhaust valve the cylinder in a constant position, such as a closed position. In some instances, the inlet valve and exhaust valve may be maintained in an open state to further slow the vehicle.

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.

Abstract: In some embodiments of the present disclosure, an electric motor is used to generate correction torques to counteract unwanted torque pulses generated by an internal combustion engine during a cylinder deactivation mode. In some embodiments, the electric motor may be mounted to an accessory drive such as a power take-off mechanism or a front end accessory drive (FEAD). In some embodiments, the correction torques may be determined using an engine model. The correction torques help to reduce or eliminate noise, vibration, and/or harshness (NVH) during the cylinder deactivation mode.

Abstract: In some embodiments of the present disclosure, an electric motor is used to generate correction torques to counteract unwanted torque pulses generated by an internal combustion engine during startup and/or shutdown. In some embodiments, the electric motor may be mounted to an accessory drive such as a power take-off mechanism or a front end accessory drive (FEAD). In some embodiments, the correction torques may be used to enforce an engine speed target profile for startup or shutdown, and may be determined using a feedback control loop based on the engine speed. The correction torques help to reduce or eliminate noise, vibration, and/or harshness (NVH) during startup and/or shutdown.

Abstract: A mobile computing device presents a set of user interface (UI) elements and receives user input corresponding to a set of vehicle specification values (e.g., engine type, transmission type, axle ratio) via the set of UI elements. The mobile computing device obtains (e.g., from a remote computer system hosted by a vehicle manufacturer) a vehicle performance value (e.g., a fuel economy value or a greenhouse gas emission value), an optimization value for the vehicle performance value, and vehicle specification analysis information based at least in part on the set of vehicle specification values. The mobile computing device presents the vehicle performance value, the optimization value, and vehicle specification feedback to a user. The vehicle specification feedback is based at least in part on the optimization value and the vehicle specification analysis information.
