Abstract

For a commercial vehicle, in particular for a fork-lift truck (10) or industrial truck, comprising: a functional arrangement comprising at least one drive motor for providing at least one working or operating function including a travelling function; and a parameterisable electronic control arrangement (12), which is configured or programmed to control the functional arrangement depending on a parameter dataset stored in the control arrangement in relation to switching on or off the working or operating function or a respective working or operating function and/or in relation to a type of implementation of the working or operating function or a respective working or operating function. It is proposed that a data memory is provided, which is rigidly attached in the vehicle, separate with respect to the control arrangement and in which at least one dataset relevant to the vehicle is stored or can be stored, the control arrangement being configured to read out data of the dataset relevant to the vehicle from the data memory (14) in a read access via a data connection (16) and/or, in a write access, to write data to the data memory (14) for recording in the dataset relevant to the vehicle or to update the dataset relevant to the vehicle.

Claims

1. Commercial vehicle, in particular fork-lift truck (10) or industrial truck, comprising:

a functional arrangement comprising at least one drive motor for providing at least one working or operating function including a travelling function;

a parameterisable electronic control arrangement (12), which is configured or programmed to control the functional arrangement depending on a parameter dataset stored in the control arrangement in relation to switching on or off the working or operating function or a respective working or operating function and/or in relation to a type of implementation of the working or operating function or a respective working or operating function;

characterised by a data memory (14), which is rigidly attached in the vehicle, separate with respect to the control arrangement and in which at least one dataset relevant to the vehicle is stored or can be stored, the control arrangement being configured to read out data of the dataset relevant to the vehicle from the data memory (14) in a read access via a data connection (16) and/or, in a write access, to write data to the data memory (14) for recording in the dataset relevant to the vehicle or to update the dataset relevant to the vehicle.

2. Vehicle according to claim 1, characterised in that the control arrangement (12), or at least one control arrangement module thereof, can be removed from the vehicle independently of the data memory (14) and can be replaced by an exchange control arrangement or an exchange control arrangement module.

3. Vehicle according to claim 1, characterised in that the data relevant to the vehicle stored in the data memory (14) comprise the parameter dataset or a part data set of the parameter dataset.

4. Vehicle according to claim 1, characterised in that the control arrangement (12) and/or the data memory (14) is configured for the control arrangement to be able to access the data memory only for reading but not writing.

5. Vehicle according to claim 1, characterised in that the control arrangement (12) and/or the data memory (14) is configured for the control arrangement to be able to access a first memory portion of the data memory only for reading but not writing and to be able to access a second memory portion of the data memory for reading and writing.

6. Vehicle according to claim 1, characterised in that the data memory (14) or the second memory portion is configured as an electrically erasable programmable read-only memory (EEPROM) or in that the data memory (14) or the first memory portion is configured as a read-only memory (ROM) or as an erasable programmable read-only memory (EPROM).

7. Vehicle according to claim 1, characterised in that the data memory (14) is rigidly installed on or in a frame or a cable harness of the vehicle.

8. Vehicle according to claim 1, characterised in that the data connection (16) comprises at least one electric data line rigidly installed in the vehicle, the data connection preferably being formed by a serial two-wire bus, in particular a synchronous serial two-wire bus, for example the so-called I²C bus or TWI bus or—

most preferably—

by a serial one-wire bus.

9. Vehicle according to claim 1, characterised in that the control arrangement (12) is configured or programmed to read out data from the data memory (14) and to check said data using data of the parameter dataset stored in the control arrangement according to at least a first checking condition, and to respond to non-fulfilment of the checking condition by triggering at least one follow-up function and/or by blocking or limiting at least one working or operating function of the functional arrangement.

10. Vehicle according to claim 1, characterised in that the control arrangement (12) is configured or programmed to read out data from the data memory (14) and to check said data using data of the parameter dataset stored in the control arrangement according to at least a second checking condition, and to respond to a fulfilment of the checking condition by clearing or deleting a limitation of at least one working or operating functional arrangement.

11. Control arrangement for a vehicle according to claim 1, characterised in that the control arrangement (12) is configured or programmed, after installation in the vehicle (10) for parameterisation in relation to this vehicle, to carry out a parameterising function, in which data is read out from the data memory (14) and stored as a parameter dataset in the control arrangement.

12. Control arrangement according to claim 11, characterised in that the control arrangement (12) is configured or programmed for the parameterising function to only be able to be carried out when no parameter dataset has previously been stored in the control arrangement, or, if a parameter dataset has previously been stored in the control arrangement, can only be carried out when an authorisation function clears this, for example on the basis of authorisation data fed to the control arrangement.

13. Control arrangement according to claim 11, characterised in that the control arrangement (12) is configured or programmed to read out data from the data memory (14) and to check said data using data of a parameter dataset previously stored in the control arrangement according to at least one checking condition, and to respond to non-fulfilment of the checking condition by triggering at least one follow-up function and/or by blocking or limiting at least one working or operating function of the functional arrangement.

14. Method for parameterising a control arrangement in relation to a vehicle according to claim 1, characterised in that data are read out from the data memory (14) rigidly attached in the vehicle and stored in the control arrangement (12) as parameter data of a parameter dataset.

15. Method for ensuring a parameter integrity and/or parameter compatibility of a parameter dataset stored in a control arrangement (12) in relation to a vehicle according to claim 1, characterised in that data are read out from the data memory (14) rigidly attached in the vehicle and compared with parameter data of a parameter dataset stored in the control arrangement (12).

16. Method according to claim 15, characterised in that the data read out from the data memory (14) and/or the parameter data of the parameter dataset are checked for data integrity.
