CLAIMS

1. Computer-implemented method for maintaining a driver's perceived trust level in an at least partially automated vehicle (1), comprising the following steps:

monitoring one or more parameters concerning the driver (6), the vehicle (1) and/or a surrounding environment;

predicting, based on the one or more parameters, a decrease in the perceived trust level; and

carrying out one or more countermeasures to compensate for the predicted decrease in the perceived trust level.

2. Computer-implemented method according to claim 1, wherein the one or more parameters comprise information related to one or more of a driver profile, vehicle specifications, traffic, weather and/or road conditions, a driver state, vehicle dynamic outputs and human-machine interface outputs to the driver (6).

3. Computer-implemented method according to claim 2, wherein the information related to the driver profile includes stored driver preferences concerning vehicle dynamic outputs and/or human-machine interface outputs to the driver (6).

4. Computer-implemented method according to claim 3, further comprising a step of updating the stored driver preferences in response to the predicted decrease in the perceived trust level.

5. Computer-implemented method according to any one of claims 2 to

4, wherein the information related to the driver profile includes information related to one or more of the driver's propensity to trust the vehicle (1) and the driver's familiarity with the vehicle (1).

6. Computer-implemented method according to any one of claims 2 to

5, wherein the information related to the vehicle specifications includes information concerning inherent attributes of the vehicle (1) with a potential impact on the perceived trust level, such as e.g. brand image or physical attributes of the vehicle (1).

7. Computer-implemented method according to any one of claims 2 to

6, wherein the information related to the traffic, weather and/or road conditions include stored itinerary information and/or information received from one or more vehicle sensors (7).

8. Computer-implemented method according to any one of claims 2 to

7, wherein the one or more vehicle sensors (7) include one or more of a radar, a LIDAR, a camera, an acoustic sensor, a rain sensor and a motion sensor.

9. Computer-implemented method according to any one of claims 2 to

8, wherein the information related to the driver state comprises physiological information received from one or more driver sensors.

10. Computer-implemented method according to any one of claims 2 to

9, wherein the physiological information include one or more of the driver's electrodermal activity, pulse rate and eye activity.

11. Computer-implemented method according to any one of claims 2 to

10, wherein the information related to vehicle dynamic outputs includes information related to current and/or upcoming steering, acceleration and/or braking of the vehicle (1).

12. Computer-implemented method according to any one of claims 2 to

11, wherein the information related to human-machine interface outputs to the driver (6) include information concerning one or more of purpose, method and sensory channel of one or more current and/or upcoming human-machine interface outputs to the driver (6).

13. Computer-implemented method according to any one of claims 1 to

12, wherein the one or more countermeasures comprise adjusting one or more of vehicle dynamic outputs and human-machine interface outputs to the driver (6).

14. A computer program product comprising a set of instructions that, when carried out by a computer, cause it to carry out the computer-implemented method of any one of claims 1 to 13.

15. A computer-readable data storage medium comprising a set of instructions that, when carried out by a computer, cause it to carry out the computer-implemented method of any one of claims 1 to 13.

16. A vehicle control system (10) adapted to carry out the computer-implemented method of any one of claims 1 to 13.

17. An at least partially automated vehicle (1) comprising a vehicle control system (10) according to claim 16.
