Abstract
A display controller calculates a driver-related fuel economy value and a performance value indicating an amount of difference between the calculated driver-related fuel economy value and a baseline value. The display controller displays the performance value on a display device during vehicle operation. A memory in the vehicle stores a number of initial fuel economy values that are replaced by the driver-related fuel economy values as new driver-related fuel economy values are calculated. An oldest fuel mileage value stored in the memory is replaced with a newly calculated fuel mileage. The baseline value used to calculate the performance value is an average of the number of the fuel economy values stored in the memory.
Claims10
A display controller for use in a vehicle, the display controller comprising:
- a first calculator configured to calculate, a driver-related fuel economy value;
- a second calculator configured to calculate a performance value that indicates a difference between the driver-related fuel economy value and a baseline fuel economy value;
- a display performer configured to control a display device to display the performance value calculated by the second calculator;
- at least one memory configured to store at least one of one or more initial fuel economy values and one or more driver-related fuel economy values;
- and
- an updater configured to update the at least one memory with the driver-related fuel economy value, wherein
- the at least one memory includes a plurality of storage areas, each of the plurality of storage areas configured to store one of the one or more initial fuel economy values or the one or more driver-related fuel economy values, the one or more initial fuel economy values stored in the plurality of storage areas before the driver-related fuel economy value is calculated, and wherein
- the updater is further configured to update the at least one memory by removing an oldest of the one or more initial fuel economy values or the one or more driver-related fuel economy values before storing a newly calculated driver-related fuel economy value to the memory;
- and wherein
- the second calculator is further configured to calculate the baseline value as an average of values stored in the plurality of storage areas.
