The method also includes calculating, using a processor, an optimal discharge rate for the known driving route, and applying, using the processor, the optimal discharge rate of the vehicle to each segment of the route.

Abstract: A system and method for optimizing a fuel efficiency of a hybrid vehicle by learning from a route history. The system may be a hybrid vehicle including an engine, a motor-generator, a battery, a battery module, a GPS unit, a memory, and a processor. The method may include detecting a current route of the hybrid vehicle, calculating a confidence value corresponding to a probability that the current route has a match in the route history, detecting a battery state of charge (SOC), determining a target SOC based on the confidence value and the route history, and adjusting an engine start/stop threshold and/or an engine power request to achieve the target SOC.

Abstract: A launch control system which maximizes hybrid vehicle acceleration from a standing start. A hybrid vehicle includes wheels, an engine, a motor-generator, a processor, and an actuation device. The processor controls an engine speed and an engine torque independently from a wheel speed and a wheel torque. While the hybrid vehicle is at a standstill, the actuation device is switched to an on state, and the engine speed and engine torque is raised to optimal values. When the actuation device is subsequently switched to an off state, the engine speed and the engine torque is applied to the plurality of wheels to launch the hybrid vehicle. The processor blends or further adjusts the torque applied to the plurality of wheels to maximize the acceleration while optimizing an amount of wheel slip. The processor then learns the launch to improve performance on subsequent launches.

Abstract: A method/system for maintaining the energy efficiency history of predicted route segments in a database, providing adaptive feedback to hybrid vehicle controls, and displaying the energy efficiency history to the driver. As the vehicle travels on a route, the system stores energy efficiency information for route segments. The system may include sensors, a memory, and a processor to learn energy efficiency information based on how fuel and battery power are used over a route segment and/or route. The method/system may utilize energy efficiency information to adjust a start/stop engine threshold of a hybrid vehicle. When the processor predicts that the vehicle will travels on the predicted route segment again, the vehicle may optimize powertrain parameters such as the start/stop engine threshold during traveling on the predicted route segment and/or before reaching the predicted route segment.

Abstract: A method/system for optimizing vehicle operations for a predicted route and/or a route set. The method/system may record location data and time data for a route. Two or more routes can be linked to form a route set by analyzing the location data and time data of the routes using a linking threshold. The linking threshold may be based on a relationship between locations and/or times of different routes. The vehicle may predict that a particular route segment or route will likely be driven. An operation of a unit or a device of the vehicle over the predicted route and/or route set may be adjusted based on information stored regarding the predicted route and/or route set in order to enhance the energy efficiency of the vehicle. The links may be categorized as having different types in order to apply a different control strategy to different types of links.

A method may include storing a driving route, parsing the driving route into a plurality of segments based on at least one of a turn detection, an intersection detection, a change in road conditions, a change in speed of the vehicle, or a predetermined distance traveled. The method may also include assigning to each segment a unique identification code, storing a plurality of values correlating to settings, the settings having values determined during a segment of the driving route, and associating each of the plurality of values to the unique identification code of the segment in which the setting was determined. The method may also include automatically changing each of the plurality of values at the beginning of each segment in which the value was altered.

The method may also include storing a known route having a plurality of segments where each segment has a corresponding battery temperature of the vehicle when the vehicle previously travelled along the segment. The method may also include providing a cooling device associated with a battery of the vehicle, initiating the cooling device during a previous time segment when the battery temperature for a particular time segment of the known route exceeds a high temperature threshold, and reducing an amount of battery power draw from the battery during the previous time segment.

If it is determined that the accelerator input is within the first range of values, an engine is controlled to provide limited or no power to a transmission. If it is determined that the accelerator input is within the second range of values, the engine is controlled to provide a substantially constant power to the transmission.
