Abstract

A signal processing apparatus for a taxi meter comprises a processor (108) and a plug (122). The plug (122) connects to a vehicle'"'"'s (100) diagnostic system (116) and receives an incoming electrical signal from the vehicle'"'"'s diagnostic system (116). The signal passes to the processor (108), the processor which convert the signal to distance data indicative of a distance travelled. The processor (108)interprets the distance data into a form suitable for reading by a taximeter and transmits the interpreted distance data to a taximeter.

Claims

1. A signal processing apparatus for a taxi meter comprising processing means and connection means, the connection means being arranged to connect to a vehicle'"'"'s diagnostic system, the connection means being arranged to receive said incoming electrical signal from the vehicle'"'"'s diagnostic system and to pass said incoming electrical signal to the processing means, the processing means being arranged to convert an incoming electrical signal from a vehicle'"'"'s diagnostic system to distance data indicative of a distance traveled, the processing means being further arranged to interpret distance data into a form suitable for reading by a taximeter, and being further arranged to transmit said interpreted distance data.

2. Signal processing apparatus according to claim 1 that is arranged to connect to the vehicle'"'"'s diagnostic system via a connector that is complimentary to that of the vehicle'"'"'s diagnostic system.

3. Signal processing apparatus according to claim 1, wherein the connection means may be a controller area network (CAN) connector.

4. Signal processing apparatus according to claim 1, wherein the connection means comprises a shaped end-piece shaped complimentarily to the connector of the vehicle'"'"'s diagnostic system.

5. Signal processing apparatus according to claim 4, wherein the end-piece and the connector are arranged to frictionally engage.

6. Signal processing means according to claim 1, wherein the connection means comprises a plug or a socket arranged to engage with a socket or a plug of the vehicle'"'"'s diagnostic system.

7. Signal processing means according to claim 1, wherein the incoming electrical signal comprises odometer data.

8. Signal processing means according to claim 1, wherein the connection means is arranged to carry a voltage from the vehicle'"'"'s diagnostic system.

9. Signal processing means according to claim 1, the voltage is arranged to power illuminated signage.

10. Signal processing means according to claim 1, wherein the processing means is arranged to convert said distance data to distance value data indicative of a monetary value associated with said distance data and being further arranged to add further value data to said distance value data if appropriate to yield a total value data.

11. Signal processing means according to claim 1, wherein the taximeter comprises display means arranged to display said total value data.

12. Signal processing means according to claim 1, wherein the processor is arranged to an output analogue signal.
