Abstract
System and method for vehicle drive cycle determination and energy management is provided. Based on a number of inputs, the system can determine the type of road that the vehicle is likely to drive on as well as the level of traffic congestion that the vehicle is likely to experience. Using these determinations, setpoints for various degrees of freedom, such as engine speed and battery power, can be set to reduce energy usage in the vehicle.
Claims20
A system for vehicle drive cycle determination and energy control for an automotive vehicle with an engine and a storage battery, the system comprising:
- a computer-readable storage medium;
- and
- a controller in electrical communication with the storage medium, the controller being configured to receive a speed signal representing speed of the vehicle, to process the speed signal to obtain a set of features characterizing a driving environment that the vehicle has experienced, to process the features to determine a drive cycle, and to generate a control signal based on the drive cycle to control charging of the storage battery with power generated from the engine.
A system for vehicle drive cycle determination and energy control for an automotive vehicle with an engine and a storage battery, the system comprising:
- a computer-readable storage medium;
- and
- a controller in electrical communication with the storage medium, the controller being configured to receive a speed signal representing speed of the vehicle at a plurality of predetermined time segments, to process the speed signal in a sequential manner to obtain, at a predetermined time interval, a set of features characterizing a driving environment including at least one road type that the vehicle has experienced, the set of features being obtained from features stored in the computer-readable storage medium, to process the set of features to determine a road type that the automotive vehicle is predicted to traverse, to determine a drive cycle based on the road type that the automotive vehicle is predicted to traverse, and to generate a control signal based on the drive cycle to control charging of the storage battery with power generated from the engine, the control signal controlling a rate of charging of the storage battery in an effort to decrease energy usage in the automotive vehicle.
A method of drive cycle determination and energy control for an automotive vehicle with an engine and a storage battery, the method comprising:
- receiving a speed signal representing speed of the vehicle;
- processing the speed signal to obtain a set of features characterizing a driving environment that the vehicle has experienced;
- processing the set of features to determine a drive cycle;
- and
- generating a control signal based on the drive cycle to control charging of the storage battery with power generated from the engine.
