Description

TITLE OF INVENTION A Motor Vehicle

FIELD OF THE INVENTION

[001] The present invention generally relates to a motor vehicle and more particularly to On Board Diagnostic systems for motor vehicles.

BACKGROUND OF THE INVENTION

[002] Vehicle manufacturers generally provide On Board Diagnostic (OBD) systems on vehicles such as two-wheelers, light-duty cars, trucks etc. These diagnostic systems monitor various parameters that affect overall functioning of the vehicle and generate data for processing. Typically, OBD systems feature a network of in-vehicle sensors that monitor the vehicle's electrical, mechanical, and emissions systems, and in response generate data that are processed by the vehicle's control unit. The data is used, for example, to detect malfunctions or deterioration in the vehicle's performance.

[003] Thus, the OBD systems generally include a standardized connector, referred to as an OBD connector/ diagnostic connector/ diagnostic port. The diagnostic port being connected to the OBD system is connected to an external scanner. Once connected, the diagnostic port provides access to the OBD system and the data from the system which is thereby retrieved by the scanner.

[004] The diagnostic connector is typically positioned either near a battery or near an engine of the vehicle. As such, ready accessibility of the diagnostic port during a repair process is a persistent concern. Further, vehicles provided with electronic fuel injection (EFI) systems require frequent diagnosis for correction of any faulty codes that may occur. Typically, such data are stored in electronic control unit (ECU) of the vehicle. However, it is not always possible and preferable to access the ECU directly, which makes the positioning of the diagnostic port critical in the vehicle layout. However, in conventional systems, in case a user or a technician wants an access to the diagnostic port, then the user or the technician normally requires a set of tools. Accessing the diagnostic port on a regular basis therefore becomes a cumbersome task.

[005] Further, since the diagnostic port is situated in a substantially non accessible region of the vehicle, replacement and servicing of the diagnostic port requires dis-assembling of multiple parts of the vehicle. This is not only an arduous task but also increases service time manifold.

[006] Hence, there is a need in the art for a motor vehicle having a diagnostic port and addressing at least the aforementioned problems.

SUMMARY OF THE INVENTION [007] The present invention is directed to a motor vehicle. The motor vehicle has a diagnostic port mounted on a vehicle component such that the diagnostic port is directly accessible by a user to obtain status of various vehicle sub-systems.

[008] In an embodiment of the invention, the vehicle component has a utility box disposed below a seat and the diagnostic port is mounted inside the utility box and accessible by opening the seat. In another embodiment, the diagnostic port is removably mounted on a side wall of the utility box.

[009] In yet another embodiment, the diagnostic port is disposed inside an electrical enclosure, the electrical enclosure having a top opening for further receiving at least one fuse, at least one relay, and at least one flasher; and a bottom opening to receive respective multi-wire cables for connecting each of the diagnostic port, the fuse, the relay, and the flasher to a vehicle wiring system. In an embodiment, the electrical enclosure has an openable and a closeable protection cap attached to the top opening for accessing the diagnostic port, the fuse, the relay, and the flasher. In a further embodiment, the electrical enclosure is a junction box. In yet another embodiment, the electrical enclosure is disposed inside the utility box.

[010] In another embodiment, the vehicle component has an aperture made thereon for receiving and fixedly mounting the diagnostic port therein. In a further embodiment, the diagnostic port is disposed inside a housing, the housing having a first opening to receive the diagnostic port, and a second opening to receive a wiring harness. In an embodiment, the housing has an openable and a closeable cap attached to the first opening for accessing the diagnostic port. In a further embodiment, the housing has an actuator for opening and closing the cap. In an embodiment, the aperture is further configured to receive the actuator such that the actuator is directly accessible by the user.

[011] In an embodiment of the invention, outer periphery of the housing has fastening means for detachably mounting the diagnostic port on the vehicle component. In another embodiment, the vehicle component is a glove box or a handlebar or a floorboard. BRIEF DESCRIPTION OF THE DRAWINGS
