Abstract
A display device for a motor vehicle having an internal combustion engine for at least temporarily driving the motor vehicle, and for displaying operating-time-related data of the internal combustion engine. The display device is characterized in that the operating-time-related data are provided as portions of the operation of the motor vehicle with a switched-off internal combustion engine at entities (E, E′, E″, . . . ) occurring earlier on the route of the motor vehicle. The display device is configured to display these data in the manner of a histogram.
Claims18
A display device for a motor vehicle having an internal combustion engine for at least temporarily driving the motor vehicle, and for displaying operating-time-related data of the internal combustion engine, characterized in that:
- the operating-time-related data are provided as portions of the operation of the motor vehicle with a switched-off internal combustion engine at entities occurring earlier on a route of the motor vehicle;
- and
- the display device is configured to display the data as a histogram.
A motor vehicle, comprising:
- an internal combustion engine for at least temporarily driving the motor vehicle;
- a control unit for calculating a percentage of time that the internal combustion engine is switched off during specified sequential entities of operation of the motor vehicle;
- a memory for storing the percentage of time that the internal combustion engine is switched off during each of a plurality of said entities as calculated by the control unit;
- and
- a display device configured to display as a histogram the stored percentage of time that the internal combustion engine was switched off for each of a selected number of the sequential entities.
A method for monitoring operation of a motor vehicle that has an internal combustion engine, the method comprising:
- measuring time during which the motor vehicle is operated with the internal combustion engine switched off during the course of a selected entity;
- calculating the percentage of time during which the internal combustion engine was switched off during the course of the entity;
- storing in a memory the percentage of time during which the motor vehicle was operated with the internal combustion engine switched off for each of a plurality of sequential entities;
- and
- displaying as a histogram on a display device the percentage of time during which the motor vehicle was operated with the internal combustion engine switched off for each of a selected number of the sequential entities.
