摘要： Methods and systems for operating a hybrid driveline that includes an engine and an electric machine are presented. In one non-limiting example, the engine and electric machine are operated according to a solution of a Hamiltonian that includes a first co-state and a second co-state, an engine fuel flow parameter, a rate of change of battery state of charge parameter, and an emissions flow rate parameter.

摘要： A hybrid vehicle includes powertrain components such as an engine, an automatic transmission, and a traction motor selectively coupled to the engine via a clutch and to the transmission. At least one controller is programmed to control these powertrain components. The vehicle is driven over a drive cycle that includes multiple engine starts and transmission gear shifts. An amount of fuel consumption used during these engine starts and transmissions gear shifts is stored on an on-board storage device. Subsequently, the engine is inhibited from starting and the transmission is inhibited from shifting gears based on the amount of fuel consumption associated with the engine starts and transmission gear shifts performed during the drive cycle as recalled from the storage device.

摘要： A system includes one or more processors configured to receive a route and receive power-usage-affecting variables. The processor(s) are further configured to break the route into a number of segments. For each segment, the processors are configured to lookup a predetermined power usage estimate, based on the received variables. Also, the processors are configured to present total estimated power usage over the route based on accumulated power usage estimates for each segment.

摘要： An exhaust gas heat recovery system for a vehicle is configured to selectively distribute a fluid heated by engine exhaust to a first path for generating electricity and a second path for heating one or more powertrain components of the vehicle. A controller selects a distribution of the fluid to the first and second paths based on minimizing a fuel consumption of an engine. The controller further selects a distribution of fluid to the powertrain components to minimize fuel consumption. The controller distributes the fluid according to the selected distribution.

摘要： Systems and methods for operating an engine that includes an exhaust gas heat recovery system are described. The system may reduce engine warm-up time and increase an amount of time an engine of a hybrid vehicle is deactivated while the hybrid vehicle is powered by a motor. In one example, a phase change material selectively stores and releases exhaust gas energy from and engine to improve vehicle operation.

摘要： Systems and methods for operating an engine that includes an exhaust gas heat recovery system are described. The system may selectively or contemporaneously supply energy from engine exhaust gas to generate electricity or warm the engine. In one example, exhaust gas energy raises a temperature of a heat transfer medium and the heat transfer medium is routed to an engine coolant heat exchanger or an expander via a bypass valve.

摘要： A vehicle includes a powertrain having an engine and at least one controller. The controller is programmed to selectively heat at least one of a plurality of components of the powertrain with a given amount of waste heat based on an expected decrease in friction power associated with an expected increase in temperature from the given amount of waste heat for each of the components.
