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.
Claims18
A method comprising:
- monitoring current engine-supplied power to a hybrid electric vehicle transmission;
- monitoring current motor generator-supplied power to the hybrid electric vehicle transmission;
- determining a current battery state of charge;
- monitoring an impact of at least one of current environmental conditions and road conditions on the amounts of the current engine-supplied power and the current motor generator-supplied power;
- and
- presenting hybrid electric vehicle performance and power usage split information comprising:
- the current engine-supplied power amount;
- the current motor generator-supplied power amount relative to the at least one of the current environmental conditions and road conditions impact;
- and
- a presentation of the current battery amount of charge on a display of the hybrid electric vehicle, proximate to the current motor generator-supplied power amount.
A hybrid electric vehicle, comprising:
- a power display circuit:
- monitoring engine-supplied power to a transmission relative to engine-supplied available power;
- monitoring motor generator-supplied power to the transmission relative to motor generator-supplied available power;
- determining a battery state of charge;
- monitoring operating conditions relating to and operating characteristics of the hybrid electric vehicle and impacts of the conditions and characteristics on the amounts of the engine-supplied available power and the motor generator-supplied available power;
- and
- a display:
- displaying power usage split information comprising:
- the engine-supplied power amount relative to the engine-supplied available power amount;
- and
- the motor generator-supplied power amount relative to the motor generator-supplied available power amount;
- and
- displaying battery amount of charge information proximate to the power usage split information.
