Abstract

A method for controlling a motor vehicle includes: ascertaining a driving strategy as a function of an environment; detecting a driving strategy of a motor vehicle driving ahead; ascertaining that the driving strategies deviate from each other; and controlling the motor vehicle in accordance with the driving strategy of the motor vehicle driving ahead.

Claims

1. A method for controlling a host motor vehicle, comprising:

generating a first driving strategy of the host motor vehicle as a function of a detected environment surrounding the host motor vehicle;

detecting a second driving strategy of a motor vehicle driving ahead;

ascertaining whether the first and second driving strategies deviate from one another; and

depending on results of the ascertaining, controlling the host motor vehicle according to the second driving strategy of the motor vehicle driving ahead including controlling linear and lateral movements of the host motor vehicle so as to emulate linear and lateral movements of the motor vehicle driving ahead.

2. The method as recited in claim 1, wherein driving strategies of multiple target motor vehicles driving ahead are ascertained and the host motor vehicle is controlled according to one of the driving strategies of the multiple target motor vehicles if the multiple target motor vehicle driving strategies correspond to one another and deviate from the first driving strategy of the host motor vehicle.

3. The method as recited in claim 1, further comprising:

supplying a control recommendation for a specified location for one of the host motor vehicle or the target motor vehicle driving ahead, based on the detected second driving strategy of the target motor vehicle driving ahead.

4. The method as recited in claim 1, further comprising:

storing the control recommendation for the specified location; and

subsequently guiding the host motor vehicle on the basis of the stored control recommendation when the host motor vehicle is traveling through the specified location again.

5. The method as recited in claim 1, wherein the second driving strategy of the motor vehicle driving ahead is checked for a risk potential, and the guidance of the host motor vehicle in accordance with the second driving strategy of the motor vehicle driving ahead takes place only if the danger potential is less than a predefined threshold value.

6. The method as recited in claim 5, wherein the first driving strategy relates to a linear control of the host motor vehicle.

7. The method as recited in claim 5, wherein the first driving strategy relates to a lateral control of the host motor vehicle.

8. The method as recited in claim 5, wherein the controlling of the host motor vehicle includes an intervention into at least one of a linear control and a lateral control of the host motor vehicle.

9. The method as recited in claim 1, wherein the controlling of the host motor vehicle includes initiating, by a processing device, an automatic or semiautomatic intervention in linear and lateral control of the host motor vehicle to control the linear and lateral movements of the host motor vehicle so as to emulate the linear and the lateral movements of the motor vehicle driving ahead.

10. The device as recited in claim 1, wherein the controlling of the host motor vehicle includes initiating, by a processing device, an automatic or semiautomatic intervention in linear and lateral control of the host motor vehicle to control the linear and lateral movements of the host motor vehicle so as to emulate the linear and the lateral movements of the motor vehicle driving ahead.

11. The method as recited in claim 1, further comprising:

providing information to the driver, via an output device, based on the results of the ascertaining.

12. A non-transitory, computer-readable data storage medium storing a computer program having program codes which, when executed on a computer, perform a method for controlling a host motor vehicle, the method comprising:

generating a first driving strategy of the host motor vehicle as a function of a detected environment surrounding the host motor vehicle;

detecting a second driving strategy of a motor vehicle driving ahead;

ascertaining whether the first and second driving strategies deviate from one another; and

depending on results of the ascertaining, controlling the host motor vehicle according to the second driving strategy of the motor vehicle driving ahead including controlling linear and lateral movements of the host motor vehicle so as to emulate linear and lateral movements of the motor vehicle driving ahead.

13. The non-transitory, computer-readable data storage medium as recited in claim 12, wherein the controlling of the host motor vehicle includes initiating, by the computer, an automatic or semiautomatic intervention in linear and lateral control of the host motor vehicle to control the linear and lateral movements of the host motor vehicle so as to emulate the linear and the lateral movements of the motor vehicle driving ahead.

14. The non-transitory, computer-readable data storage medium as recited in claim 12, wherein the method further comprises providing information to the driver, via an output device, based on the results of the ascertaining.

15. A device for controlling a host motor vehicle, comprising:

a scanning device configured to scan an environment of the host motor vehicle and scan a region of a motor vehicle driving ahead; and

a control unit including a processor configured to (i) generate a first driving strategy for the host motor vehicle as a function of the environment of the host motor vehicle, (ii) ascertain a second driving strategy of the motor vehicle driving ahead based on the scan of the region of the motor vehicle driving ahead, and (iii) control the host motor vehicle according to the second driving strategy of the motor vehicle driving ahead if the first and second driving strategies deviate from one another, wherein the control includes controlling linear and lateral movements of the host motor vehicle so as to emulate linear and lateral movements of the motor vehicle driving ahead.

16. The device as recited in claim 15, further comprising:

an output device to output information to the driver based on results of the ascertaining.
