device (170) accessible on the portable apparatus (100). Alternatively, the vehicle hardware itself may be equipped with the GPS device, ECU (500) sends such information from the GPS device through the communication device (600) to the portable apparatus (100).
[0049] The portable apparatus (100) has stored in its memory the user feed data which may be inputted through user input device (120) of the portable apparatus (100). Alternatively the vehicle operational status naonitoring system (146) may download such information from the internet directly. The vehicle operational status nionitoring system (146) can use such information so downloaded or inputted by the user as a threshold values for other commutations or display purposes.
[0050] The vehicle operational status monitoring system (146) is adapted to perform including but not limited to the below actions:
1. The vehicle operational status monitoring system (146) is adapted to download or inputed the vehicle's maintenance plan. When the portable apparatus (100) is paired to thr ECU (500) it received the information such as total km run by the vehicle.

3. The vehicle operational status monitoring system (146) indicates the nearest assistance center in order to assist the user in case of need or in case of service alarm.
4. The vehicle operational status monitoring system (146) diaplays the information / data on the display with more or less graphic details, mentioning some of the data acquired from the ECU (500) or by the portable apparatus (100) (for example RPM, Throttle position, instantaneous consumption, engine speed, vehicle speed, engine temperature, atmospheric temperature and pressure, torque, power, etc.)
[0051] Oftentimes, it is difficult for a user to judge the state of vehicle or state of driving condition, and hence it is necessary to display the information in such maimer so that user can decide the state of vehicle or state of driving condition at a glance. For example many a times, it is difficult for a user to decide based on the . different values being displayed on the display of the portable apparatus (100) as to if he is driving at the best economy mode or not.
[0052] The vehicle operational status monitoring system (146) of the portable apparatus (100) provides a graphical pattern indicative of economy mode of instantaneous driving condition that enable the user to change the state of the vehicle while driving to enable the driver to drive the vehicle to achieve the best economical mode of the vehicle.
[0053] User selects the feature from the vehicle operational status monitoring system (146) to see the economy mode of instantaneous driving condition. The portable apparatus (100) starts receiving the data / information'related to engine RPM from the ECU (500) via communication device (600). Similarly, the portable apparatus (100) starts receiving the data / information related to fiiel consumption from the ECU (500) via communication device (600). Further, the portable apparatus (100) starts receiving the data / information related to speed

IPO DMLHZ e5: -.QZ- i.B 15 17 : 1:1

from the ECU (500) via communication device (600). This data / information that is engine RPM and fuel consumption and the speed is for a small time period, time period could be second or millisecond or microsecond. In an embodiment, the portable apparatus (100) receives data / information from the vehicle state detecting means (700) such as sensors and switches via communication device (600).
[0054] Then the portable apparatus (100) checks for the distance travelled by the vehicle in the same time period for which data / information related to fuel consumption and engine RPM is received. Based on the data / information related to fiiel consumption for a time period and distance travelled by the vehicle in the same time period the fuel consumption per unit distance and.fuel consumption per unit time is calculated. The vehicle operational status monitoring system (146) also calculates average engine RPM. The vehicle operational status monitoring system (146) also calculates the average speed. The vehicle operational status monitoring system (146) also calculates average fiiel consumption.
[0055] As illustrated in the Figure 4, on the display of the portable apparatus (100) a plot is created with average engine RPM or average speed as x-axis and the average fuel consumption as y-axis and instantaneous average values are depicted therein on the plot. In an embodiment, said instantaneous average values are depicted by a visible dot (10). In an embodiment, said instantaneous average values are depicted by a visible circle (10). In an embodiment, said instantaneous average values are depicted by any other suitable manner.
[0056] The ECU (500) keeps on updating the values and sends to the portable apparatus (100) and hence the-location of the visible circle (10) keeps on changing on the plot.
[0057] Every location of the visible circle (10) has particular coulour associated with it. When the position of the visible circle (10) changes, colour also changes.
14
.Lfctr Q5-Q2:-2:Qi5 1.7 : LL'

In an embodiment, the two colour are used, for example red and green. In an embodiment, the colurs are of varying intensities. In an embodiment, three colours are used, for example red, yellow and green.
[0058] The vehicle operational status monitoring system (146) has inbuilt zone (20) which is overlapping with the plot having average engine RPM or average speed as x-axis and the average fuel consumption as y-axis and which is representing the best economy zone for the vehicle. In an embodiment, the inbuilt zone (20) can be visible or hidden.
[0059] In an embodiment, if the average engine RPM or average speed and the average ftiel consumption is within the range of this zone, it indicates that all the vehicle state parameters are maintained in such position that leading to optimum driving condition "of the vehicle.
[0060] If any of the parameter, vehicle parameter or any external parameter, changes, the position of the visible circle (10) on the plot also changes and consequently the colour of the visible circle (10) will also change. In an embodiment, as the visible circle (10) moves away from the inbuilt zone (20) the colour of the visible circle (10) becomes incrementaly more red, similarly, as the visible circle (10) moves towards the inbuilt zone (20) the colour of the visible circle (10) becomes incrementaly more green. In an embodiment, as the visible circle (10) moves away from the inbuilt zone (20) the colour of the visible circle (10) becomes decremently lesser green then becomes yellow and then becomes incrementaly more red, similarly, as the visible circle (10) moves towards the inbuilt zone (20) the colour of the visible circle (10) becomes decremently lesser red then becomes yellow and then incrementaly more green.
[0061] When the driver drives the vehicle with excessive opening of the throttle leading to uneconomical mode, the visible circle (10) moves away from the inbuilt zone (20) and its colour changes from green to yellow to red. This is the
15

indication to the driver to change the state of the driving to achieve the optimum economy mode.
[0062] Similarly, if the driver throttles the vehicle with brake and or clutch in, partially or fully, pressed condition again the visible circle (10) moves away from the inbuilt zone (20) and its colour changes from green to yellow to red. This is the indication to the driver to change the state of the driving to achieve the optimum economy mode.
[0063] Further, if the driver is driving in lower gear with excessive opening of the •throttle the visible circle (10) moves away from the inbuilt zone (20) and its colour changes from green to yellow to red. This is the indication to the driver to change the state of the driving to achieve the optimum economy mode.
[0064] When the colour of the visible circle (10) is green it indicates the optimum driving condition of the vehicle.
[0065] In an embodinient, an audio indication / signal is generated to alert the driver when visible circle (10) moves away from the inbuilt zone (20). In an embodiment, an audio indication / signal is generated to alert the driver when the visible circle (10) enters 7 lies in the inbuilt -zone (20). In an embodiment, the audio indications / signals when the visible circle (10) moves away from the inbuilt zone (20) and enters / lies in the inbuilt zone (20) are different.
[0066] In an embodiment, when visible circle (10) moves away from the inbuilt zone (20) the size of the visible circle (10) changes. For example, the size of •visible circle (10) increases as the visible circle (10) moves away from the inbuilt zone (20). Alternatively, the size of visible circle (10) decreases as the visible circle (10) moves away from the inbuilt zone (20).

[0067] As illustrated in the Figure 5, on the display of the portable apparatus (100) a plot is created with the engine / vehicle performance as x-axis and the average fuel consumption as y-axis and instantaneous average values are depicted therein on the plot. In an embodiment, the plot has varied color intensity with one , color e.g. RED at top left comer and the GREEN color at right bottom comer. The GREEN color represents the better performance and the RED is warning for the rider indicating that vehicle is not in economy mode.
[0068] Thus, the graphical representation on the portable apparatus (100) helps the driver to sense the state of vehicle or state of driving condition at a glance and change it to achieve the optimum driving condition of the vehicle.
[0069] In an embodiment, the vehicle itself can b^^dapted to have inbuilt apparatus which is capable of displaying the information and or the graphical patterns described hereinabove. In such cases the paring of apparatus, havirig display units, with the ECU (500) is not required. In such cases, the ECU (500) is configured to undertake the calculations and communicate with apparatus to display the information.
