An electronic parking disc (2) containing a display (4) that communicates with an electronic clock (6), where signal wires (8, 32) communicates with an acceleration detector (10) and a gyro detector (30) for connecting the detectors to a signal processing unit (12). An electronic connection (20) goes from the processing unit (12) to a memory unit (14) that receives a time signal over a databus (16) from the electronic clock (6) and where the memory unit (14) over databus (18) transmits a signal to display (4) containing segments (22, 24, 26, 28) |
