Abstract

A method for generating action recommendations for the driver of a rail vehicle or control signals for the rail vehicle by way of a driver assistance system. Taking at least one journey specification into account, driving data is calculated and on the basis of the driving data: an action recommendation is generated and displayed in an action recommendation display device or a control signal that acts on a vehicle control device is generated. In order to optimize such a method in relation to an energy requirement of the rail vehicle, at least one air pressure characteristic variable is taken into account as a journey specification.

First claim

The invention claimed is:

1. A method of generating action recommendations for the driver of a rail vehicle or control signals for the rail vehicle, the method comprising:
detecting an air pressure characteristic variable as a detection value;
calculating driving data with a driver assistance system and thereby taking into account at least one air pressure characteristic value forming a journey specification and also taking into account a factor which is stored in a database as a function of the detection value; and
based on the driving data:
generating an action recommendation and displaying the action recommendation in an action recommendation display device; or
generating a control signal acting on a vehicle control device.

2. The method according to claim 1 , which comprises repeatedly detecting the air pressure characteristic variable during a journey.

3. The method according to claim 1 , which comprises detecting the air pressure characteristic variable with a sensor unit on board the rail vehicle.

4. The method according to claim 1 , which comprises detecting the air pressure characteristic variable by way of a detection of an altitude characteristic variable.

5. The method according to claim 4 , which comprises deriving the altitude characteristic variable on a basis of location information.

6. The method according to claim 5 , which comprises detecting the location information by way of a locating unit.

7. The method according to claim 5 , wherein the location information is determined on the basis of stored route data.

8. A driver assistance system for generating action recommendations for the driver of a rail vehicle or control signals for the rail vehicle, the system comprising:
a computing unit configured for calculating driving data taking into account at least one air pressure characteristic variable forming at least one journey specification;
said computing unit being configured for generating action recommendations for the driver of the rail vehicle and control signals for the rail vehicle; and
an action recommendation display device disposed to receive from said computing unit calculated driving data and configured for displaying the action recommendation generated based on the driving data; or
a vehicle control device disposed to receive from said computing unit the calculated driving data and subject to the control signal generated on a basis of the driving data.

9. A rail vehicle, comprising a driver assistance system according to claim 8 .
