Vehicle Control Device
The purpose of the present invention is to improve fuel efficiency during coasting by calculating, with high accuracy, travel resistance during coasting. This vehicle control device comprises: a first travel resistance acquisition unit that acquires a first travel resistance, which is determined on the basis of road information or external information; and a second travel resistance acquisition unit that acquires a second travel resistance, which is determined on the basis of the result of actual traveling of the vehicle. This vehicle control device determines the content of coasting travel control during traveling of the vehicle on the basis of the result of a comparison of the first travel resistance and the second travel resistance in a predetermined zone where the vehicle has actually traveled.
Method and system for increasing engine braking
A method of increasing engine braking of an engine for a vehicle, the method including: determining the change in kinetic energy of the vehicle over a period; determining the energy output from a drivetrain of the vehicle over the period; comparing the change in kinetic energy to the energy output; and increasing the engine braking of the vehicle when the change in kinetic energy is greater than the energy output over the period.
Adaptive in-drive updating of energy consumption prediction for vehicle with a load
A system for adaptive in-drive updating, for a vehicle travelling on a route, includes a controller having a processor and tangible, non-transitory memory. The vehicle is carrying a load. The controller is adapted to obtain one or more dynamic parameters pertaining to the load. A plurality of adaptive predictors is selectively executable by the controller at a timepoint during the route at which a completed portion of the route has been traversed by the vehicle and a remaining portion remains untraversed. The plurality of adaptive predictors includes a speed predictor configured to generate a global speed profile. The plurality of adaptive predictors includes a driving consumption predictor is configured to predict a driving consumption profile for the remaining portion of the route based in part on the dynamic parameter, the route features, the global speed profile, and a past drive consumption.

Systems and methods for energy efficient mobility using machine learning and artificial intelligence
Systems and methods for energy efficient mobility are provided. The method may include identifying a vehicle moving on a road, calculating a first energy required to complete a trip, determining a size of an air pocket zone of the vehicle, calculating a second energy required to transition to the air pocket zone of the vehicle and to complete the trip in the air pocket zone of the vehicle, and transitioning to the air pocket zone of the vehicle if the second energy is more energy efficient than the first energy.
Roundtrip range projection
An automated method that determines a roundtrip range of a vehicle includes: retrieving a set of parameters associated with the vehicle; retrieving map information regarding a geographic area including multiple links associated with available roadways in the geographic area and each link includes a cost value; determining a set of roundtrip range projection links by evaluating the links to identify multiple roundtrip paths extending radially outward from the vehicle by: determining a total cost of an outbound path and a return path, where the paths meet at a common node; and including the common node in a range projection polygon if a summed cost for a set of links included in the outbound path and the return path is less than a target cost; and generating and displaying a map of at least a portion of the geographic area and a set of range projection polygons overlaid onto the map.

A control system of a mining machine controls a driving device that drives a traveling device of the mining machine. The control system includes an acceleration command value calculation unit that calculates an acceleration command value for accelerating the mining machine, a correction value calculation unit that calculates a correction value for the acceleration command value based on a first driving force component of the driving device to cause the mining machine to travel at a target traveling speed and a second driving force component of the driving device to offset a resistance component against traveling of the mining machine, an addition processing unit that calculates a correction acceleration command value by adding the acceleration command value and the correction value, and an acceleration command value output unit that outputs the correction acceleration command value to the driving device.
VEHICLE MASS AND ROAD LOAD ESTIMATION IN AN EV CONDITION
Systems and methods provide accurate determinations of relevant vehicle mass that can take into account any load being carried and/or towed by a vehicle, such as an electric vehicle or hybrid vehicle. Systems and methods also provide accurate road load measurements that can take into account road gradient(s) and the impact of gravity. Accordingly, the dynamic nature of relevant vehicle mass and road load can be captured. Efforts to optimize operation and/or take preemptive action to provide more efficient performance, enhance the drive experience, etc. can be better achieved through the more accurate determinations of relevant vehicle mass and road load achieved by these systems and methods.
Vehicle, system, and method of calculating an engine torque request value
A method of calculating an engine torque request value for a vehicle includes a vehicle controller receiving an regeneration torque request value corresponding to a regeneration torque to be generated by an energy recovery mechanism. The vehicle controller further receives a desired acceleration value, and calculates the engine torque request value based on the regeneration torque request value and the desired acceleration value. The vehicle controller may then operate the engine in accordance with the engine torque request value.
Device and method for controlling motor output of a hybrid vehicle
A hybrid vehicle control device for controlling a hybrid vehicle with an engine and an electric motor as drive sources of the vehicle includes a high-load road travel determination unit configured to determine whether or not the vehicle is traveling on a high running resistance road surface on which a predetermined vehicle acceleration is unobtainable only by an output of the engine, and a motor output setting unit configured to set an output of the electric motor. If the vehicle is determined to be traveling on the high running resistance road surface by the high-load road travel determination unit, the motor output setting unit limits the output of the electric motor when a vehicle speed reaches a predetermined vehicle speed.
