Abstract

The present application relates to a communication system for controlling the output of messages to a vehicle occupant. The communication system has a processor configured to output a first message to the vehicle occupant. A signal is received from one or more sensors operative to monitor the vehicle occupant when the first message is output. The signal from said one or more sensors is analysed to determine one or more parameters relating to the response of the vehicle occupant to said first message. The communication system controls the subsequent output of at least said first message in dependence on said one or more determined parameters. The present application also relates to a method and to a vehicle.

First claim

The invention claimed is:

1. A communication system for controlling the output of messages to a vehicle occupant, the communication system comprising one or more processors configured to:
output a first message to the vehicle occupant;
receive a signal from one or more sensors that monitor the vehicle occupant;
analyse the signal from the one or more sensors to determine one or more parameters relating to a response of the vehicle occupant to the first message, wherein the one or more parameters provide identification of a negative response by the vehicle occupant to the first message;
implement a counter to count negative responses;
implement a second counter; and
control subsequent output of the first message in dependence on the counter and the second counter.

2. The communication system of claim 1 , wherein the one or more parameters provide identification of a positive response by the vehicle occupant to the first message and the counter counts positive responses.

3. The communication system of claim 2 , wherein the one or more processors is configured to calculate a probability of a driver responding positively or negatively to the first message.

4. The communication system of claim 1 , wherein the one or more sensors comprise an audio sensor and the one or more processors are configured to analyse an audio signal output from the audio sensor.

5. The communication system of claim 4 , wherein the audio sensor is operative to detect a spoken response from the vehicle occupant and the one or more processors are configured to analyse the spoken response to determine one or more characteristics.

6. The communication system of claim 1 , wherein the one or more sensors comprise at least one image sensor, and wherein the one or more processors are configured to analyse an image signal output from the at least one image sensor.

7. The communication system of claim 6 , wherein the one or more processors are configured to analyse the image signal to identify one or more of the following:
(a) a movement of the vehicle occupant;
(b) a gesture performed by the vehicle occupant;
(c) a facial expression of the vehicle occupant to assess attentiveness of the occupant; and
(d) a facial expression of the vehicle occupant to assess emotional status of the occupant.

8. The communication system of claim 1 , wherein the one or more processors are configured to control the output of the first message by:
(a) inhibiting output of the first message for at least a first defined time period;
(b) defining an output format for the subsequent output of the first message; and
(c) adjusting a frequency with which the first message is output.

9. The communication system of claim 1 , wherein the one or more processors are configured to control the output of the first message in dependence on workload of the vehicle occupant.

10. The communication system of claim 1 , wherein the one or more processors are configured to control the output of the first message in dependence on data received from one or more sensors arranged to detect vehicle situational data.

11. A vehicle, comprising:
one or more sensors; and
a communication system coupled to the one or more sensors that controls output of messages to a vehicle occupant, the communication system comprising one or more processors configured to:
output a first message to the vehicle occupant;
receive a signal from one or more sensors that monitor the vehicle occupant;
analyse the signal from the one or more sensors to determine one or more parameters relating to a response of the vehicle occupant to the first message, wherein the one or more parameters provide identification of a negative response by the vehicle occupant to the first message;
implement a counter to count negative responses;
implement a second counter; and
control subsequent output of the first message in dependence on the counter and the second counter.

12. A method of controlling the output of messages to a vehicle occupant, the method comprising:
outputting a first message to the vehicle occupant;
using one or more sensors to monitor the vehicle occupant;
analysing a data signal from the one or more sensors to determine one or more parameters relating to a response of the vehicle occupant to the first message, wherein the one or more parameters provide identification of a negative response by the vehicle occupant to the first message;
electronically counting negative responses;
electronically implementing a second counter; and
controlling the subsequent output of at least the first message in dependence on the count of negative responses and the second counter.

13. The method of claim 12 , wherein the one or more parameters provide identification of a positive response by the vehicle occupant to the first message, and wherein the method further comprises counting positive responses.

14. The method of claim 13 , wherein the one or more processors are configured to calculate a probability of a driver responding positively or negatively to the first message.

15. The method of claim 14 , wherein the one or more processors are configured to determine when to output the first message in dependence on the calculated probability.

16. The communication system of claim 3 , wherein the one or more processors are configured to determine when to output the first message in dependence on the calculated probability.

17. The communication system of claim 1 , wherein controlling subsequent output comprises changing a method of interaction.
