Abstract

A driving data recording device for a motor vehicle for collecting at least one of time- and speed-dependent data and including, housing having an element for securing the housing to a housing shell of a motor vehicle drive gear, a control module for processing collected data and located in the housing, and a memory located in the housing and cooperating with the control module.

Claims

1. A driving data recording device for a motor vehicle for collecting at least one of time- and speed-dependent data, the recording device comprising a housing having means for fixedly securing the housing to a housing shell of a motor vehicle drive gear;

a control module for processing collected data and located in the housing; and

memory means located in the housing and cooperating with the control module.

2. A driving data recording device according to claim 1, wherein the memory means comprises a non-volatile memory for storing actual driving data, and wherein the recording device further comprises an energy accumulator for protecting the actual driving data stored in the non-volatile memory in case of an interruption of external voltage supply.

3. A driving data recording device according to claim 1, further comprising means for electrically connecting the housing of the recording device with a motor vehicle chassis.

4. A driving data recording device according to claim 1, further comprising a plurality of conductors for connecting the recording device with external devices, and wherein at least one of the plurality of conductors is formed as a light guide.

5. A driving data recording device according to claim 1, further comprising means for recording the driving data by a compressed, redundancy-reduced coding.

6. A driving data recording device according to claim 1, wherein the memory means comprises means for storing the driving data with a high chronological accuracy of dates and times of a day, and wherein the recording device further comprises means for connecting the storing means with an external data display capable of fetching out and reconstructing the stored driving data.

7. A driving data recording device according to claim 1 further comprising an internal timer, and a synchronization device for adjusting the internal timer to an exact date and time if the date and the time of the timer do not correspond to date and time signals of an external precise timer.

8. A driving data according device according to claim 1, further comprising an electrical generator for supplying at least partially power necessary for operation of the recording device.

9. A driving data recording device recording to claim 8, wherein the generator comprises at least one permanent magnet and a coil which generate, during movement of the motor vehicle, an alternative current, the generated alternative current representing a speed signal of a motor vehicle speed.

10. A driving data recording device according to claim 1, wherein the control means comprises means for executing partial programs consisting of comparatively short, interrupt, signal-triggered program portions with a comparatively high computation output.
