Abstract
Systems and methods are provided for presenting in a hybrid electric vehicle display, proximate to or in some relation to each other, engine power usage, motor-generator power usage, and battery state of charge information. By combining the display of engine power usage, motor-generator power, and battery state of charge information, power distribution and related information may be presented to the operator of a vehicle to explain the vehicle's performance from a power split output and usage perspective. This can provide reassurance or confirmation that the vehicle is operating as it should, identify a problematic condition, etc.
Claims7
A method of controlling a vehicle power usage split between engine-supplied power and motor generator-supplied power for a hybrid electric vehicle, the method comprising:
- receiving first data indicating a current engine-supplied power to a transmission of the hybrid electric vehicle;
- receiving second data indicating a current motor generator-supplied power to the hybrid electric vehicle transmission;
- determining a current battery state of charge;
- determining, based on the received first and second data, an impact of at least one of current environmental conditions and road conditions on an amount of the current engine-supplied power and an amount of the current motor generator-supplied power;
- and
- controlling a power usage split of the hybrid electric vehicle based on:
- the current engine-supplied power amount relative to the at least one of the current environmental conditions and road conditions impact;
- the current motor generator-supplied power amount relative to the at least one of the current environmental conditions and road conditions impact;
- and
- the current battery state of charge.
