Now referring to the drawings wherein the descriptions are for the purpose of illustrating preferred embodiments of the invention only, and not for the purpose of limiting the same.
In the instant invention intelligent acquisition of Customer Driving Pattern in Engine ECU has proved to be really a beneficial feature. Implementation of this feature requires only development cost and can be implemented in any existing Engine ECUs of today’s vehicles in the market provided these ECUs can accommodate some additional data processing and portion of its memory.
In existing vehicles in the market, there is a technology to record lot in information in Engine ECU such as DTCs (Diagnostic Trouble Codes) of any malfunctions, Engine parameters such as air or fuel adaptations to correct vehicle ageing related combustion inefficiencies, Vehicle parameters such as VIN, ECU flashing counter, ECU software version no, Total kms covered. However, there is no technology available which can give information regarding customer driving pattern during the life of the vehicle. Such information will be useful to understand the consumer market better and help in designing the future products. For example - If vehicle

manufacturer gets updated information regarding at what engine speed and load vehicles are driven by various different types of customers in different demographically evolving cities, it can design its engine and gearbox to give maximum fuel efficiency and performance benefit to customers. Similarly, mode based kilometer run record will help better in knowing the trend followed by Customers. This data will be very useful in designing multi-mode configuration of future vehicles. But as on date, this data is not being stored in any of the vehicle in the market for the lifetime and future retrieval purposes. Currently, many manufacturers who offer multi-mode vehicles in the market are processing information such as 1) Real-time engine speed & engine load 2) kms driven. But all of these manufacturers are using this real-time information to automatically shift to suggested drive mode for the customer. None of these is storing this information for lifetime for future retrieval.
The main purposes to develop this information were to obtain engine operation record as per load and engine speed with percentage run in different zones, and kilo metres travelled in various modes. For e.g. - eco, city apart from other driving conditions.
Engine operation record, the computation of Engine driving state for various Engine Load Vs Engine speed is stored in a memory matrix of m x n. Where, m = number of calibration points of Engine load. n = number of calibration points in Engine speed. Engine Load calibration points cover 0 to 200%, step size of 10%. Engine Speed calibration points support 0 to 8000 rpm, step size of 500rpm. The accumulation of data is initiated automatically when engine starts. The periodicity of accumulation data counter is calibrateable (minimum interval can be 100ms). On every successful ECU shutdown, data is stored in ENVRAM. Memory blocks each of 4 bytes can be allocated in ENVRAM for each cell of the matrix.
This kind of feature is first in its kind and can prove beneficial if used across various vehicle platforms. Special Data Analytic Tool with restricted access can read the Vehicle History data over vehicle CAN bus. The tool read and convert this data into required percentage duration record of Engine Load Vs Engine Speed for entire lifetime of the vehicle up to date. Kilometres travelled in various modes. For e.g. - eco, city etc. As soon as customer select the drive mode
5

switch, kilometres accumulation shift to the ECU mileage memory that is designated for that particular drive mode. The least count is 100 meters.
The main advantages of above Customer Driving Pattern data acquisitions are that they help in evaluating customer driving habits and contribute to designing drive mode configuration, engine hardware and gear ratios for upcoming project. This data also proves beneficial for developing fuel efficiency improvement guidelines for the customer.
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes but is not limited to," etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an" should typically be interpreted to mean "at least one" or "one or more"); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, typically
6

means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, and C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to "at least one of A, B, or C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, or C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B."
The foregoing description is a specific embodiment of the prevent invention. It should be appreciated that this embodiment is described for the purpose of illustration only and that numerous alteration and modification may be practiced by those skill in the art without departing from the spirit and scope of the invention. It is intended that all such modification and alteration included in so far as they come within the scope of the invention as clamped the equivalent thereof.
