Abstract

Claims (26)

1. A method for generating driving instructions driver of an electrically driven vehicle, comprising the following steps:

acquiring route information for at least one route section of a driving route lying ahead of the vehicle;

determining temperature information, acting in a temperature-varying fashion on at least one drive component of the vehicle, for the at least one route section on the basis of the route information; and

outputting a driving instruction to the driver on the basis of the temperature information for the at least one route section.

2. The method as claimed in claim 1 , wherein the route information has at least one of the following route parameters for the route section:

curve profile of the route section;

gradient profile of the route section;

underlying surface of the route section; and

weather information for the route section.

3. The method as claimed in claim 1 , wherein the temperature information has at least one of the following temperature parameters for the route section:

expected power consumption of the at least one drive component;

cooling capacity for the at least one drive component; and

heating situation for the at least one drive component.

4. The method as claimed in claim 1 , further comprising the step of determining an expected heating capacity for at least one mode of operation of the vehicle on the at least one route section on the basis of the route information.

5. The method as claimed in claim 4 , further comprising the steps of (i) determining a change in temperature on the basis of the expected heating capacity, and (ii) using a current temperature of the at least one drive component as a basis for the outputting of the driving instruction.

6. The method as claimed in claim 5 , further comprising the steps of (i) determining the current temperature of the at least one drive component, and (ii) subsequently accounting for the current temperature during the outputting of the driving instruction to the driver.

7. The method as claimed in claim 1 , wherein the driving instruction to the driver includes a predefinition for a performance request by the driver for the at least one drive component.

8. The method as claimed in claim 1 , wherein the outputting of the driving instruction to the driver has a color coding.

9. An instruction device for generating driving instructions for a driver of an electrically driven vehicle, comprising:

an acquisition module for acquiring route information for at least one route section of a driving route lying ahead of the vehicle,

a determining module for determining temperature information acting in a temperature-changing fashion on at least one drive component of the vehicle, for the at least one route section on the basis of the route information, and

an output module having a display device for outputting a driving instruction to the driver on the basis of the temperature information for the at least one route section.

10. The instruction device as claimed in claim 9 , wherein the acquisition module, the determining module and the output module are configured to execute the following method:

acquiring route information for at least one route section of the driving route lying ahead of the vehicle;

determining the temperature information acting in temperature-varying fashion on the at least one drive component of the vehicle, for the at least one route section on the basis of the route information; and

outputting the driving instruction to the driver on the basis of the temperature information for the at least one route section.
