Abstract

A method and a device for event interpretation and output of operating instructions in motor vehicles are described. The inventive idea is to bundle the wealth of information regarding errors and/or defects resulting from the multitude of sensors and the complexity of modern vehicles, optionally linking it with empirical findings and outputting operating instructions to the driver, so that the instructions do not make excessive technical demands of the driver but instead are adapted to his/her instantaneous situation. The core of the inventive concept is to use an electronic database which contains the technical information including the error codes of devices of the automotive sensor and electronic systems for analysis of event information which informs the driver comprehensively and yet comprehensibly regarding the problems that have occurred. Likewise the database may be the target of an inquiry initiated by the driver.

Claims

1. A method of performing an event interpretation and outputting an operating instruction in a motor vehicle system, comprising:

compiling event information with respect to a vehicle-relevant event from devices of the vehicle electronic system and vehicle sensor system;

analyzing the event information by comparison with error codes of the devices stored in a database system and more extensive information regarding the error codes; and

outputting the operating instruction to a driver as a function of the analyzed event information, wherein the operating instruction is a problem solving instruction for a driver action in response to the event information.

2. The method as recited in claim 1, wherein the vehicle-relevant event includes one of:

a system-diagnosed error in the devices,

one of reaching and exceeding a critical threshold value of a quantity measured by a sensor,

an occurrence of a predefined signal pattern emanating from the devices, and

an inquiry by the driver.

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

analyzing the event information by comparison with predefined information regarding an error code combination.

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

querying a signal of an additional device in order to perform an error diagnosis whenever at least one of a predetermined error code combination and a predetermined event combination occur.

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

outputting the operating instruction to the driver acoustically via an audio output unit.

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

operating an input/output device present in the vehicle for at least one of;

inputting at least one of a message and an inquiry, and

outputting the operating instruction to the driver.

7. A device, comprising:

a system monitor for compiling event information with respect to a vehicle-relevant event from devices of the vehicle electronic system and vehicle sensor system and for analyzing the event information by comparison with information stored in a database system regarding error codes of the devices; and

an interface for an output of an operating instruction to a driver as a function of the analyzed event information, wherein the operating instruction is a problem solving instruction for driver action in response to the event information.

8. The device as recited in claim 7, further comprising:

an input device for input of at least one of a message and an inquiry by the driver.

9. The device as recited in claim 7, further comprising:

an additional interface for a wireless connection to a remote database for retrieving information regarding at least one of the error codes and error code combinations.

10. The device as recited in claim 7, further comprising:

a database for retrieving information regarding at least one of the error codes and error code combinations.

11. A memory card for connection to a device, comprising:

a database for storing one of error codes and error code combinations together with respective operating instructions, at least one of the error codes and the error code combinations being based on devices of at least one of a vehicle electronic system and a vehicle sensor system, and the operating instructions being outputtable to a driver.
