Abstract
A vehicle computer system (e.g., on-board vehicle computer system) obtains a fuel economy performance goal for a vehicle (e.g., an engine speed goal or a vehicle speed goal) that is based on a configuration of the vehicle; calculates a count of events in which a current value exceeds the goal; compares the count of events with a threshold count; and generates one or more notifications based at least in part on the comparison (e.g., for display on an operator interface). The vehicle computer system also calculates an engine speed and a vehicle speed score for a driver of the vehicle based at least in part on comparisons of current speeds with the speed goals. Scoring and other data may be displayed or stored for further processing.
Claims17
A non-transitory computer-readable medium having stored therein computer-executable instructions configured to cause a computer system on board a vehicle to perform steps comprising:
- obtaining a fuel economy performance goal for the vehicle, wherein the fuel economy performance goal is based at least in part on a configuration of the vehicle, and wherein the fuel economy performance goal is an engine speed goal or a vehicle speed goal;
- calculating a count of events in which a current value exceeds the fuel economy performance goal, wherein the current value is a current engine speed or a current vehicle speed;
- performing a comparison of the count of events with a threshold count;
- generating one or more notifications based at least in part on the comparison, wherein the one or more notifications include an indicator of driver performance relative to the fuel economy performance goal;
- and
- presenting the one or more notifications via an operator interface of the vehicle.
A non-transitory computer-readable medium having stored therein computer-executable instructions configured to cause a computer system on board a vehicle to perform steps comprising:
- obtaining fuel-economy performance goals for the vehicle, wherein at least one of the fuel economy performance goals is based at least in part on a configuration of the vehicle, and wherein the fuel economy performance goals comprise an engine speed goal and a vehicle speed goal;
- determining whether at least one vehicle operating condition is satisfied;
- based on at least one vehicle operating condition being satisfied:
- performing a comparison of a current engine speed with the engine speed goal;
- calculating an engine speed score for a driver of the vehicle based at least in part on the comparison of the current engine speed with the engine speed goal;
- performing a comparison of a current vehicle speed with the vehicle speed goal;
- and
- calculating a vehicle speed score for the driver of the vehicle based at least in part on the comparison of the current vehicle speed with the vehicle speed goal;
- and
- outputting the engine speed score and the vehicle speed score via an operator interface of the vehicle.
A computer-implemented method performed by a computer system, wherein the computer system includes an operator interface on board a vehicle, the method comprising:
- obtaining fuel-economy performance goals for the vehicle, wherein at least one of the fuel economy performance goals is based at least in part on a configuration of the vehicle, and wherein the fuel economy performance goals comprise an engine speed goal and a vehicle speed goal;
- determining whether at least one vehicle operating condition is satisfied;
- based on at least one vehicle operating condition being satisfied:
- performing a comparison of a current engine speed with the engine speed goal;
- calculating an engine speed score for a driver of the vehicle based at least in part on the comparison of the current engine speed with the engine speed goal;
- performing a comparison of a current vehicle speed with the vehicle speed goal;
- and
- calculating a vehicle speed score for the driver of the vehicle based at least in part on the comparison of the current vehicle speed with the vehicle speed goal;
- and
- outputting the engine speed score and the vehicle speed score via the operator interface.
