Abstract
Systems and methods for operating a vehicle that may be driven to or sold in different geographical locations that may have different engine emissions and fuel economy standards are described. The systems and methods may adjust vehicle operation to comply with standards that may be enforced where the vehicle is geographically located. The standards may apply to countries, treaty zones, race track areas, off-road areas, and other geographically related standards.
Claims20
An operating method for a vehicle, comprising:
- storing a plurality of vehicle calibrations to read-only memory of a controller;
- estimating a position of a vehicle in response to the data;
- loading a base calibration from the plurality of vehicle calibrations into random-access memory of the controller, and generating a revised calibration via copying parameters from an alternate calibration included in the plurality of vehicle calibrations into random access memory of the controller based on the position of the vehicle;
- and
- adjusting one or more actuators responsive to the vehicle calibration parameters.
A system, comprising:
- an engine;
- a motor/generator;
- a transmission mechanically coupled to the engine and the motor/generator;
- and
- a controller including executable instructions stored in non-transitory memory that cause the controller to copy a baseline calibration from read-only memory to random access memory, copy an alternative calibration from the read-only memory to the random access memory and overwrite portions of the baseline calibration copied into random access memory, the baseline calibration and the alternative calibration included in a plurality of calibrations stored in the read-only memory, the alternative calibration selected according to a vehicle's geographical location.
An operating method for a vehicle, comprising:
- storing a plurality of different calibrations, including different size calibrations, in read-only memory of a controller;
- loading a base calibration from the read-only memory to random-access memory of the controller;
- overwriting a portion of the random-access memory that includes the base calibration with an alternative calibration that is copied from the read-only memory, the alternative calibration selected in response to a geographical position of the vehicle changing, and where the alternative calibration includes fewer vehicle calibration parameters than the base calibration;
- and
- adjusting one or more actuators responsive to calibration parameters stored in the random-access memory.
