DETAILED DESCRIPTION 10 [00011] One of the fastest growing areas in communication technology involves telematics control units embedded in vehicles. A telematics control unit provides wireless communication functions such as unlocking the doors of a vehicle, disabling an alarm, determining the location of a vehicle, and accessing call-center information. [00012] Telematics refers to the integrated use of telecommunications devices and systems 15 and information storage, usage, transmitting, receiving, and processing. More simply, telematics refers to sending, receiving and storing, information via telecommunication devices. In addition, telematics devices and system have been applied alongside Global Positioning System (“GPS”) technology integrated with computers and mobile communications technology in automotive information and navigation systems. 20 [00013] Other than the convergence of telecommunications and information processing, the term telematics may also refer to automation of various processes relating to the driving and using of automobiles. For example, the telematics control unit can report emergency situations to a telematics services provider's central location via a voice telephony call over a wireless communications network, or a message sent electronically 25 over a network, including a wireless communications network and the Internet. Telematics control unit also includes services such as GPS navigation, integrated hands-free cellular telephony, wireless safety communications, and automatic driving assistance and information systems, such as traffic, restaurant, fuel, and emissions information.
4
[00014] The term telematics control unit is coined to automobile systems that combine global positioning system (GPS) satellite tracking and wireless communications for automatic roadside assistance and remote diagnostics. This combination provides consumers with a multitude of services not previously available.
[00015] In recent years, increasingly sophisticated telematics control unit have been 5 developed to detect vehicle locations as well as the speed and direction at which the vehicle is traveling. Telematics control unit has been developed for monitoring fixed customer locations as well as for vehicle applications, especially in the case of vehicle collision or crash condition.
[00016] Vehicle accidents/crashes are a common occurrence in many parts of the world, 10 and the number of vehicle accidents increases each year with the increase of vehicles on the road. When a collision occurs while driving, the owners of accident-involved vehicles may occupy the road for hours to preserve evidence at the spot where the accident took place. As a result, traffic may be congested for a long time.
[00017] Generally, when dealing with the accident, the most important things are to 15 evaluate which vehicle caused the accident and to quantify the degree of damage. When a collision occurs while driving, the subject vehicles move a distance from an initial accident site except for some specific cases. Unless speed marks are generated or witnesses from the collision scene are found, objective evidence is lost, and there will be continuing controversy over the circumstances of the accident. Therefore, insurance 20 companies, the police, and the owners of the vehicles will be burdened with economical and time losses while determining the circumstances of the accident. Furthermore, in the case of a collision with a vehicle, unless the owner of a damaged vehicle or a witness is present on the site, it may be difficult to acquire accident information if the driver of the vehicle causing the collision does not get in touch with the owner of the damaged vehicle. 25
[00018] Hence, upon detecting a crash condition, the on-board system that is telematics control unit, activates a cellular transceiver to initiate a cellular telephone call to a call center of the telematics service provider (TSP). Upon connection to the call center, the system may communicate certain data, such as location determined by global positioning satellite (GPS) processing, identification data and crash related data. After the data 30 transmission, the call is converted to a voice call in which a TSP representative at the call
5
center can attempt voice communication with an occupant of the vehicle. The TSP also offers mechanisms for the representative to contact emergency service personnel in the area, to respond appropriately to the incident. More recently, such systems have been enhanced to offer other related services, such as navigation services like turn-by-turn directions. GPS based on-board navigation systems have also become common, which 5 provide the vehicle operator with location and velocity information. [00019] Telematics units within mobile vehicles provide subscribers with connectivity to a telematics service provider (TSP). The TSP provides subscribers with an array of services ranging from emergency call handling and stolen vehicle recovery to vehicle system status and diagnostics monitoring, global navigation system aided position identification, 10 map services, and turn-by-turn navigation assistance. Telematics control units are often provisioned and activated at a point of sale when a subscriber purchases a telematics-equipped vehicle. Upon activation, the telematics control unit can be utilized to provide subscribers/users with a variety of telematics-facilitated services such as those described herein. 15 [00020] New methods of vehicle time sharing have been developed in recent years in response to increased opportunities for monetizing the idle capacity of unused vehicles. Automobile rental services have targeted, for example, locations where the costs of owning and storing a vehicle are high relative to potential owners' available cash flows and where potential owners are likely to use vehicles for only a small percentage of the 20 total available time. Meanwhile, more traditional automobile rental business models, such as those that maintain large vehicle fleets in the vicinity of airports to cater to business travelers and vacationers, have remained successful. [00021] Also, automobile rental services and other automobile owners who intend to rent, loan or share their automobiles with other drivers may maintain accounts linking the 25 telematics units with TSPs to preserve the functionality of telematics units for their customers and/or share groups. [00022] Further, taking example of a vehicle immobilizer and the telematics control unit, the telematics control unit works slightly different from the vehicle immobilizer. Conventionally, the immobilizer is known to immobilize the vehicle to protect it from 30 theft etc. The immobilizer works only when the phone is in the vicinity of the vehicle,
6
meaning thereby, immobilizer is for only short distance. The telematics control unit covers the wide range as compared to the vehicle immobilizer, as the telematics control unit works through GSM and GPS. Taking example of a scenario, if someone intentionally took or steals the vehicle pre equipped with telematics control unit, then the user or owner can immobilize the vehicle remotely through the mobile phone since it is 5 connected to the telematics control unit. So, the telematics control unit ensures the anti-theft property. [00023] Therefore, from the above mentioned paragraphs it is quite clear that the telematics control unit has become an important part of the mobile vehicle in recent times. It is imperative for the telematics control unit to be located in the vicinity capable 10 of sensing data. The proximity of telematics control unit with neighboring components helps to perform its intended function in an efficient manner. The location of the telematics control unit and access to the air flow in the vehicle plays an important role in maintaining the efficiency and accuracy of the data sent by the telematics control unit, as the telematics control unit has an inbuilt antenna over it. This particular antenna needs to 15 be in contact with the outer frequency to send the required data. The telematics control unit is mostly mounted on a frame member of a vehicle, for example mounted below seat assembly or anywhere in the compact location. The telematics control unit in this location is without any air flow. The absence of flow of air affects the efficiency of the telematics control unit as the frequency of the telematics control unit would not get synchronized 20 with the radio frequency and hence the telematics control unit might not perform satisfactorily or may be rendered dead e.g. a mobile phone in the basement without signal. Further, the frame member is prone to vibration and noise, which also affects the efficiency of the telematics control unit. So, there is a need of improved mounting the telematics control unit in a frame member so that the efficiency and the accuracy of data 25 should not get hampered by the metal contact, by maintaining the constant flow of air, and also should not get hampered by the vibration and noise of the frame member.
[00024] In known art, the telematics control unit is mounted under a fuel tank assembly in a recess formed between a lower portion of a fuel tank assembly and a main tube of a vehicle frame member, towards a rear portion of a fuel tank assembly for a motorcycle 30 type saddle vehicle. This arrangement raises problem that is, the conventional layout of
7
the fuel tank changes to accommodate telematics control unit. Further, the telematics control unit is prone to vibration and rattling noise because of the interference with the inner portion of fuel tank assembly. The disposition of the telematics control unit in a recess formed leads to further problem, that is, the telematics control unit is not easily accessible at the time of servicing, that is one has to remove the fuel tank assembly, only 5 then the telematics unit can be accessed. Further, such disposition results in change in design or change in location of the conventional parts in the compact layout, thereby increasing cost, undesirably high lead time for change over as well as more variety in parts.
[00025] Hence, there exists a challenge of designing an improved mounting scheme, 10 which can satisfactorily accommodate electronic components like telematics control unit within a compact layout of a saddle type vehicle while maintaining a constant air flow in the vicinity and ensuring ease of accessibility. Additionally there exists a challenge of designing a flexible platform architecture solution to mount the telematics control unit which is to be implemented in a variety of vehicle variants & platforms without any 15 major change in design and manufacturing set-up of the range of vehicles.
[00026] Therefore, there is a need to have an improved mounting scheme for the telematics control unit for a saddle type vehicle which overcomes all of the above problems and other problems known in art.
[00027] The present subject matter discloses a mounting bracket for the telematics control 20 unit to ensure the stable mounting of the telematics control unit and also, make it as theft proof.
[00028] As per one aspect of present invention, a frame assembly of the motorcycle type saddle vehicle comprises of a head pipe, a main frame, a down frame etc. The main frame is extended rearward from the head pipe. Further, as per one aspect of the present 25 invention, a fuel tank assembly is mounted on the main frame with various attachment means, for example, fasteners. The down frame extended backward after it is extended downward from the front of the main frame. As per one aspect of the present invention, a frame reinforcement member is integrally attached with the main frame and down frame. The frame reinforcement member extends from the head pipe and supports initial part of 30 the main frame and the down frame. Further, a support frame member that is cross frame
8
member acting like a bridge is integrally diagonally attached with the main frame and the down frame of a frame member. This configuration provides support to the main frame and the down frame of the frame assembly and hence, ensuring the rigidity of the frame assembly.
[00029] Further, as per one aspect of the present invention, the frame reinforcement 5 member has C shaped profile. As per one aspect of the present invention, a mounted bracket is mounted on left side of a frame reinforcement member with various attachment means, for example, fasteners. The mounting bracket includes a pair of arms and a depressed portion/groove. The first arm is having a slot or an opening which compliments with an opening present on the frame reinforcement member. Hence, the mounting 10 bracket is detachably attached to the frame reinforcement member with a fastener. Further, the depressed portion/ groove present on the mounting bracket act as the self-guiding bracket as it follows the trajectory of the frame reinforcement member, ensuring fool-proof or error proof assembly of the mounting bracket with the frame reinforcement member. Thereby, restricts the wrong assembly of the mounting bracket. 15
[00030] Further, as per one aspect of the present invention, the arm B has a straight profile and at rear end has a pair of projected profile (referred here as projected profile). The projected profile of the arm B conforms to a profile present on a housing member, for example rubber boot. The housing member has a profile to detachably accommodate a telematics control unit. The telematics control unit is detachably attached to the mounting 20 bracket with a housing member. Therefore, the telematics control unit assembly is detachably attached to the mounting bracket, separated by a gap with respect to the cross frame member, preventing the telematics control unit from sagging and also, restricting the unit from fouling with other components. This mounting scheme ensures that the efficiency of the telematics control unit is not affected by the vibration generated and a 25 eliminates any direct contact with the metal member of the frame member. The mounting scheme ensures the constant flow of air in the vicinity of the telematics control unit as it maintains the gap between the metal member and the telematics control unit. This mounting means also ensures the rigid mounting of the telematics control unit. The constant flow of air helps to synchronize the frequency of the telematics unit with the 30
9
radio frequency. This mounting scheme also ensures that the mounting of the telematics control unit is theft proof.
[00031] Further, as per an additional embodiment of the present invention, an ignition coil is mounted on a support frame member opposite to the mounting of the telematics control unit, that is on the right hand side of the frame member, ensuring the optimization of 5 wiring harness.
[00032] In the ensuing exemplary aspects, the vehicle is a two wheeler saddle type vehicle. However, it is contemplated that the concepts of the present invention may be applied to any of the two wheeler including hybrid electric vehicle and electric vehicle.
