摘要： A system and approach for a vehicle system. The vehicle system may include a vehicle, a propulsion device (e.g., a combustion engine or electric motor), and a controller. The propulsion device may at least partially power the vehicle. The controller may be in communication with the propulsion device and may control the propulsion device according to a target speed of the vehicle. The controller may include a model of energy balances of the vehicle and may use the model to estimate energy losses over a travel horizon of the vehicle. The controller may optimize a cost function over the travel horizon of the vehicle based at least in part on the estimated energy losses to set an actual speed for the vehicle. The estimated energy losses may include one or more of aerodynamic drag, vehicle friction, and conversion efficiency from the propulsion device.

摘要： Aspects of the disclosure are directed to characterizing effective vehicle frontal area. As may be implemented in accordance with one or more embodiments, one or more operating parameters of the vehicle are obtained. Such parameters may be obtained during one or more qualifying periods of time, such as those periods in which an operating parameter or parameters such as speed and/or acceleration are within a range of values. A value that provides an estimate of the vehicle frontal area is then generated based on the one or more operating parameters.

摘要： Systems, methods, apparatuses, and computer program products are provided for determining carbon emissions of one or more vehicles. For instance, in one example embodiment, an apparatus may calculate miles traveled by the vehicles along a predefined route and may calculate a fuel usage of the vehicles for traveling along the route to obtain one or more fuel values. The apparatus may also analyze data indicating the miles traveled and the fuel values to determine fuel efficiency values corresponding to the vehicles traveling the route. The apparatus may also determine an estimate of an amount of carbon emissions for each of the vehicles based in part on applying at least one carbon emission value to respective fuel values associated with corresponding determined fuel efficiency values.

摘要： A lane change device, a system including the same, and a method thereof are provided. The lane change system includes a sensor unit that senses a rotational angular velocity of a turn signal lever of a subject vehicle, an electric field signal of a gear lever of the subject vehicle, and distances between the subject vehicle and neighboring vehicles. A processor then sets a driving mode using the rotational angular velocity, the electric field signal, and the distances between the subject vehicle and the neighboring vehicles, generates a lane change path based on the driving mode, and executes a lane change of the subject vehicle.
