Abstract

A method, apparatus and computer program for producing driver information, where at least some of the driver information is produced in the form of haptic driver information on a control means of a vehicle, includes ascertaining a measure of a haptic contact between the driver of the vehicle and the control means for controlling the vehicle and producing the driver information based on the ascertained measure of the haptic contact between the driver and the control means on the control means as haptic driver information and/or producing auxiliary driver information that corresponds to the driver information and that is perceptible to the driver via a different perception channel.

First claim

What is claimed is:

1. A method for producing and transmitting driver information, wherein at least part of the driver information is produced as haptic driver information on a control element of a vehicle, the method comprising:
ascertaining a measure of a haptic contact between a driver of the vehicle and the control element via which the driver drives the vehicle;
selecting for production, based on the ascertained measure of the haptic contact, at least one from among the following:
the haptic driver information on the control element, and
non-haptic driver information that is perceptible by the driver via a non-haptic perception channel; and

producing the selected of: the haptic driver information on the control element, and the non-haptic driver information perceptible by the driver via the non-haptic perception channel.

2. The method as claimed in claim 1 , wherein the amplitude and/or frequency and/or the duration of the haptic driver information to be produced varies or is set based on the ascertained measure of the haptic contact between the driver of the vehicle and the control element for controlling the vehicle.

3. The method as claimed in claim 2 , wherein at least one vibration parameter in the vehicle is ascertained as a measure of vibrations prevailing in the vehicle at present or in the near future and said at least one vibration parameter is taken as a basis for at least one of:
adjusting the amplitude and/or frequency of the haptic driver information,
adjusting a time interval or a starting time for output of the haptic driver information,
moving the production of at least part of the haptic driver information to other parts of the vehicle.

4. The method as claimed in claim 1 , wherein at least one vibration parameter in the vehicle is ascertained as a measure of vibrations prevailing in the vehicle at present or in the near future and said at least one vibration parameter is taken as a basis for at least one of:
adjusting the amplitude and/or frequency of the haptic driver information,
adjusting a time interval or a starting time for output of the haptic driver information,
moving the production of at least part of the haptic driver information to other parts of the vehicle.

5. The method as claimed in claim 4 , wherein producing the haptic driver information on the control element of the vehicle is brought forward or put back in time based on the ascertained measure of the haptic contact and/or based on the at least one ascertained vibration parameter, and/or is split into at least two parts, and/or is adjusted to suit a particular time interval or an event.

6. The method as claimed in claim 5 , wherein an amplitude pattern and/or frequency pattern of the haptic driver information is chosen or adjusted based on the ascertained measure of a haptic contact between the driver of the vehicle and the control element for controlling the vehicle, and/or based on the at least one ascertained vibration parameter.

7. The method as claimed in claim 5 , wherein the ascertained measure of a haptic contact between the driver of the vehicle and the control element for controlling the vehicle and/or the at least one ascertained vibration parameter is/are taken as a basis for the driver information as auxiliary driver information being at least partially moved to at least one other perception channel of the driver.

8. The method as claimed in claim 4 , wherein an amplitude pattern and/or frequency pattern of the haptic driver information is chosen or adjusted based on the ascertained measure of a haptic contact between the driver of the vehicle and the control element for controlling the vehicle, and/or based on the at least one ascertained vibration parameter.

9. The method as claimed in claim 8 , wherein the ascertained measure of a haptic contact between the driver of the vehicle and the control element for controlling the vehicle and/or the at least one ascertained vibration parameter is/are taken as a basis for the driver information as auxiliary driver information being at least partially moved to at least one other perception channel of the driver.

10. The method as claimed in claim 4 , wherein the ascertained measure of a haptic contact between the driver of the vehicle and the control element for controlling the vehicle and/or the at least one ascertained vibration parameter is/are taken as a basis for the driver information as auxiliary driver information being at least partially moved to at least one other perception channel of the driver.

11. The method as claimed in claim 4 , wherein the at least one vibration parameter is ascertained based on unevennesses of a road area travelled on by the vehicle in the present time interval or in a time interval in the near future.

12. The method as claimed in claim 4 , wherein the at least one vibration parameter is ascertained based on at least one of the following:
information about a condition of a road from a digital navigation map;
sensor data of an ambient sensor of the vehicle configured to detect part of the road travelled on by the vehicle;
sensor data of a vertical dynamic sensor of the vehicle;
sensor data of an inertial sensor and/or acceleration sensor of the vehicle;

a characteristic quantity representing a rotation speed or current gear of a drive system of the vehicle; and/or
sensor data of a motion and/or force sensor on the manual control element of the vehicle.

13. The method as claimed in claim 4 , wherein
the haptic driver information comprises one or more frequency components having a respective amplitude and a respective frequency; and
the amplitude and/or frequency of the one or more frequency components of the haptic driver information is adjusted based on the measure of a haptic contact between the driver of the vehicle and the control element for controlling the vehicle and/or based on the at least one ascertained vibration parameter.

14. The method as claimed in claim 4 , wherein
the at least one ascertained vibration parameter represents a current measure of vibrations in the vehicle and a predicted future change in the measure of vibrations in the vehicle, and
the predicted future change in the measure of vibrations of the vehicle is ascertained based on a planned trajectory of the vehicle.

15. The method as claimed in claim 4 , wherein the haptic driver information is to be output in an upcoming time interval, and wherein the at least one ascertained vibration parameter relates to at least part of the upcoming time interval.

16. The method as claimed in claim 1 , wherein the amplitude, frequency or pattern of the haptic driver information is chosen such that the haptic driver information is below a disturbance threshold for the driver of the vehicle at which the haptic driver information is perceived as substantially uncomfortable, wherein the disturbance threshold is chosen based on the vibration parameters in the vehicle and/or based on the measure of the haptic contact between the driver of the vehicle and the control element for controlling the vehicle.

17. A computer program product embodied in a non-transitory computer readable storage medium to produce and transmit driver information, wherein at least part of the driver information is produced as haptic driver information on a control element of a vehicle, the computer program product comprising processor executable instructions to:
ascertain a measure of a haptic contact between a driver of the vehicle and the control element via which the driver drives the vehicle;
selecting for production, based on the a
