DESC:FIELD OF THE INVENTION

The present disclosure relates to the field of automobiles. Particularly, the present disclosure relates to a system for a Range Change Inhibitor (RCI) unit for providing feedback of improper working of the RCI unit installed in a vehicle.

BACKGROUND

Automobiles such as heavy-duty commercial vehicles are equipped with a transmission system having a gearbox and a Range change Inhibitor (RCI) unit. The gearbox includes a gear change shaft for shifting the gear. The RCI unit is adapted to inhibit unintentional gear downshifts that can cause a sharp increase in the load on the transmission system of the vehicle. For instance, the RCI unit is installed in a 9-speed gearbox of the vehicle to avoid the direct shifting of gears from a high range (8,7,6,5) to a low range (4,3,2,1), wherein the high range includes eighth, seventh, six, and fifth gear positions, and the low range includes fourth, third, second and first gear positions. When the RCI unit is working normally, the RCI unit prevents the direct shifting of gear from high range to low range until the engine speed is lowered.

On the other hand, when the RCI unit is not working properly, the RCI unit may not prevent the direct shifting of gear from the high range to the low range. As a result, the driver may downshift from the high range gears to low range gears at high speed resulting in a sharp increase of load on the gearbox. In some scenarios, a sudden shifting of gears will lead to damage in planetary gear shifting assembly due to rapid engagement and disengagement. .

Therefore, in view of the above-mentioned problems, there is a need to provide a system for a Range Change Inhibitor (RCI) unit that can eliminate one or more above-mentioned problems associated with existing RCI units.

SUMMARY

This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the disclosure. This summary is neither intended to identify key or essential inventive concepts of the disclosure and nor is it intended for determining the scope of the disclosure.

The present disclosure provides a system for a Range Change Inhibitor (RCI) unit. The system may include a relay unit, a feedback unit, and a control unit. The relay unit may be adapted to electrically couple the RCI unit to a power source based on an actuation signal. The control unit may be connected to the RCI unit via the relay unit adapted to supply electric power to the RCI unit via the relay unit. The control unit may be adapted to receive an input signal to determine a state of the RCI unit, wherein the state is one of an operational state and a non-operational state of the RCI unit. The control unit may be adapted to generate a feedback signal for the relay unit when the state is determined to be the non-operational state. Further, the feedback unit may be electrically connected to the relay unit and adapted to generate one of an aural feedback and a visual feedback based on the feedback signal.

Further, a vehicle is disclosed herein. The vehicle may include a gear change shaft, a Range Change Inhibitor (RCI) unit, and a system for the RCI unit. The gear change shaft may be adapted to enable a shifting of a gear of the vehicle. The Range Change Inhibitor (RCI) unit may be adapted to engage or disengage with a guide plate 104. The RCI unit physically stops the lever to shift from high range to low range with the help of guide plate mounted above the gear change shaft. The system may include a relay unit, a feedback unit, and a control unit. The relay unit may be adapted to electrically couple the RCI unit to a power source based on an actuation signal. The control unit may be connected to the RCI unit via the relay unit adapted to supply electric power to the RCI unit via the relay unit. The control unit may be adapted to receive an input signal to determine a state of the RCI unit, wherein the state is one of an operational state and a non-operational state of the RCI unit. The control unit may be adapted to generate a feedback signal for the relay unit when the state is determined to be the non-operational state. Further, the feedback unit may be electrically connected to the relay unit and adapted to generate one of an aural feedback and a visual feedback based on the feedback signal.

Moreover, a Range Change Inhibitor (RCI) assembly for a vehicle is disclosed herein. The RCI assembly may include a Range Change Inhibitor (RCI) unit and a system for RCI unit. The RCI unit includes a plunger adapted to be engaged with a guide plate to restrict the motion of the gear change shaft of transmission shifter turret assembly of the vehicle which further restricts a direct shifting of gear from a high range to a low range without lowering a speed of the vehicle. The system may include a relay unit, a feedback unit, and a control unit. The relay unit may be adapted to electrically couple the RCI unit to a power source based on an actuation signal. The control unit may be connected to the RCI unit via the relay unit adapted to supply electric power to the RCI unit via the relay unit. The control unit may be adapted to receive an input signal to determine a state of the RCI unit, wherein the state is one of an operational state and a non-operational state of the RCI unit. The control unit may be adapted to generate a feedback signal for the relay unit when the state is determined to be the non-operational state. Further, the feedback unit may be electrically connected to the relay unit and adapted to generate one of an aural feedback and a visual feedback based on the feedback signal.

As explained above, the feedback unit of the system may generate one of the aural feedback and the visual feedback to indicate a driver of the vehicle the RCI unit is in the non-operational state. This is an indicative that the RCI unit is not working, such that the driver shall not directly shift the gear from the high range to the low range without lowering the speed of the vehicle. This prevents the structural failure of the gearbox which will be very expensive to repair. Further, the system may prevent accidents of the vehicle by preventing the structural failure of the gearbox.

Embodiments of the present disclosure will be described below in detail with reference to the accompanying drawings.

Figure 1 illustrates a close-up view of a transmission unit 102 of a vehicle 100 having a Range Change Inhibitor (RCI) unit 106 and a guide plate 104, according to an embodiment of the present disclosure. Further, Figures 2(a) and 2(b) illustrate arrangements of the RCI unit 106 and the guide plate 104 depicting different operating positions of the RCI unit 106, according to an embodiment of the present disclosure. Referring to Figures 1, 2(a), and 2(b), the vehicle 100 may include the transmission unit 102, a guide plate 104, the RCI unit 106, and a system 400 for the RCI unit 106. The transmission unit 102 may include a gear change shaft and the system 400. The gear change shaft may be adapted to enable a shifting of a gear of the vehicle 100. The RCI unit 106 may be adapted to engage or disengage with the guide plate 104 to restrict or allow, respectively, the motion of the gear change shaft of a transmission shifter turret assembly of the vehicle which further restricts a direct shifting of gear from a high range to a low range without lowering a speed of the vehicle 100. In an embodiment, the gearbox may include the gear change shaft coupled to the guide plate 104.

The guide plate 104 may include at least one slot 104-2 adapted to receive a plunger 114 (shown in Figure 3) of the RCI unit 106. Herein, the RCI unit 106 may be operated in a first operating position and a second operating position to engage or disengage with the guide plate 104. The engagement of the RCI unit 106 with the guide plate 104 may restrict the direct shifting of gear from a high range to a low range without lowering a speed of the vehicle 100. This prevents the shifting of gears which leads to damage in planetary gear shifting assembly of the vehicle 100 due to rapid engagement and disengagement. Herein, the system 400 (shown in Figure 4) may be adapted to generate feedback of an operational state of the RCI unit 106.

In the first operating position as shown in Figure 2(a), the RCI unit 106 may be disengaged from the at least one slot 104-2 of the guide plate 104. Herein, the RCI unit 106 may not prevent the direct shifting of gear from the high range to the low range. In the second operating position as shown in Figure 2(b), the RCI unit 106 may be engaged with the at least one slot 104-2 of the guide plate 104. In an embodiment, the plunger 114 of the RCI 106 may be engaged with the at least one slot 104-2 of the guide plate 104. Herein, the RCI unit 106 prevents the direct shifting of the gear from the high range to the low range without lowering the speed of the vehicle 100. Thus, the driver may shift the gear from the high range to the low range upon lowering the speed of the vehicle 100.

The constructional and operational details of the RCI unit 106 are explained with reference to the Figure 3.

Figure 3 illustrates an exploded view of the RCI unit 106, according to an embodiment of the present disclosure. Referring to Figure 3, the RCI unit 106 may be installed in a commercial vehicle to prevent the direct shifting of the gear from high range 8,7,6,5 to low range 4,3,2,1 without lowering the speed of the vehicle 100.

The RCI unit 106 may include a housing 108, a solenoid member 110, a solenoid-piston 112, the plunger 114, and an inlet 116. Further, the RCI unit 106 may include a stopper body 118, a steel ball 120, a spring 122, a sealing washer 124, a sealing plastic 126, a seal rubber 128, an outer O-ring 130, an inner O-ring 132, a core 134, at least one washer 136, a plurality of bolts 138, at least one screw 140, at least one sealing member 142, and a name plate 144.

The housing 108 is adapted to at least partially accommodate the spring 122, the solenoid-piston 112, the sealing plastic 126, the seal rubber 128, the plunger 114, the at least one washer 136, and the at least one sealing member 142. The solenoid member 110 and the solenoid-piston 112 may be coupled to the housing 108 via the plurality of bolts 138. The solenoid member 110 may be adapted to receive a connector adapted to supply the power to the RCI unit 106 through the solenoid member 110. Further, the inlet 116 may be connected to a pressure tank adapted to supply a predefined amount of pressure to the RCI unit 106. In an embodiment, the predefined amount of pressure may be from 6 bar to 12 bar, without departing from the scope of the present disclosure. Herein, the RCI unit 106 may be operated based on the supplied the power and the predefined amount of pressure.

The RCI unit 106 may be adapted to connect with a control unit 402 of the system 400 to receive the voltage from the control unit 402 through the solenoid member 110 to operate the RCI unit 106. The RCI unit 106 may include the plunger 114 adapted to be activated upon receiving the power and the predefined amount of pressure. In an embodiment, the control unit 402 may be embodied as electronic control unit (ECU) 402. In the subsequent paragraphs, the control unit 402 may be interchangeably referred to as ECU 402, without departing from the scope of the present disclosure.

Upon activation, the plunger 114 moves downwardly to engage with the guide plate 104 for locking the gear change shaft. This prevents the direct shifting of the gears from the high range 8,7,6,5 to the low range 4,3,2,1 unless the speed of the vehicle 100 is reduced by the driver. When the RCI unit 106 is in working condition, the plunger 114 is activated and the RCI unit 106 is getting the signal from the ECU 402. If there is non-supply of voltage from the ECU 402 to the RCI unit 106, this represents the non-working condition of the RCI unit 106. In the non-working condition of the RCI unit 106, a warning lamp 408 indicates the driver so that the driver will not directly shift gears from the high range 8,7,6,5 to the low range 4,3,2,1 without lowering the speed of the vehicle 100. In an embodiment, a commercial vehicle may be an Indian commercial vehicle such as a truck. In another embodiment, some other factors such as failure of the plunger 114, and a pressure drop in a pump of the vehicle 100 may also be responsible for the non-working of the RCI unit 106.

Figure 4 illustrates a schematic view of the system 400 for the RCI unit 106 having the warning lamp 408, according to an embodiment of the present disclosure while Figure 5 illustrates a schematic view of the system 400 having the warning lamp 408 and a buzzer 414, according to another embodiment of the present disclosure. Referring to Figures 4 and 5, the system 400 may be adapted to give feedback or warning about the improper working and non-working of the RCI unit 106 in the vehicle 100. The RCI unit 106 may be installed in the 9-speed gearbox of the vehicle in order to avoid the direct shifting of gears from the high range (8,7,6,5) to the low range (4,3,2,1). Herein, the high range includes eighth, seventh, sixth, and fifth gear positions, and the low range includes fourth, third, second, and first gear positions. When the RCI unit 106 is in an operational state, the RCI unit 106 prevents the direct shifting of gear from high range to low range without lowering the speed of the vehicle 100.

The system 400 may include a relay unit 404, a feedback unit, and the control unit 402 such as the ECU 402. The relay unit 404 may be adapted to electrically couple the RCI unit 106 to a power source 410 such as a battery 410 based on an actuation signal. The control unit 402 may be connected to the RCI unit 106 via the relay unit 404 adapted to supply electric power to the RCI unit 106 via the relay unit 404. The control unit 402 may be adapted to receive an input signal to determine a state of the RCI unit 106. The state is one of the operational state and the non-operational state of the RCI unit 106. Further, the control unit 402 may be adapted to generate a feedback signal for the relay unit 404 when the state is determined to be the non-operational state. The feedback signal of the non-operational state of the RCI unit 106 may be transmitted to one of the relay unit 404 and the feedback unit.

The relay unit 404 may be adapted to electrically connect the RCI unit 106, the control unit 402, and the feedback unit with each other. The relay unit 404 is an integrated circuit having a pin-1, a pin-4, a pin-5, a pin-8, a pin-9, a pin-12, a pin-13, and a pin-14. The pin-1 may be adapted to connect to the feedback unit and a pin-5. The pin-5 may be adapted to connect with the pin 9 and RCI unit 106. The pin-9 may be connected to the pin-5 and the RCI unit 106, and the pin-4 may be connected to a pin-8. The pin-8 may be adapted to connect the pin-12, and the pin-13 may be connected to the RCI unit 106. Further, the pin-13 and pin-14 are adapted to connect the ECU 402 with RCI unit 106, and to connect the battery 410 with the RCI unit 106.

The feedback unit is electrically connected to the relay unit 404 and adapted to generate one of an aural feedback and a visual feedback based on the feedback signal received from the control unit 402. The feedback unit may include an indication device 408, 414 positioned on a dashboard of the vehicle 100. The indication device 408, 414 may be adapted to provide one of the aural feedback and the visual feedback to a driver of the vehicle 100. In an embodiment, as shown in Figure 4, the indication device 408, 414 may include a warning lamp 408. The warning lamp 408 may be adapted to generate the visual feedback based on the feedback signal received from the control unit 402. The warning lamp 408 may be embodied as a Light-Emitting Diode (LED). In another embodiment, as shown in Figure 5, the indication device 108, 114 may include the warning lamp 408 and a buzzer 414. The buzzer 414 may generate the aural feedback based on the feedback signal received from the control unit 402.

The warning lamp 408 may be adapted to connect with the pin-1 of the relay unit 404, and the warning lamp 408 is also connected with the battery 410 and RCI unit 106. The components of the system 400 such as the ECU 402, the relay unit 404, the RCI unit 106, the warning lamp 408, and the battery 410 are electrically connected with one another.

When the RCI unit 106 is not working, the positive pin of the battery 410 will connect with pin-9 which is already connected with pin-1 of the relay unit 404. In such a situation, no signal will be sent from ECU 402 to the RCI unit 106, so the warning lamp 408 will glow, and that will notify to driver that the RCI unit 106 is not in working condition, or improper working condition. Thus, the warning lamp 408 is adapted to indicate to the driver that the RCI unit 106 is not in working condition so that the driver shall not shift the gear from high range to low range without lowering the speed of vehicle 100. The warning lamp 408 is installed on the dashboard of the vehicle 100 for causing awareness to the driver about the non-working of RCI unit 106 or improper working condition.

On the other hand, the warning lamp 408 will get off when RCI unit 106 is actuated by means of voltage supplied by the ECU 402. When power is supplied from the ECU 402, the power will flow from pin-14 and pin -13, and the pin-9 will connect to the pin -5 of the relay unit 404, so the RCI unit 102 will be actuated, and warning lamp 408 will be off. In such a situation, the RCI unit 106 prevents the shifting of gear from the high range to the low range unless the speed is reduced by the driver.

In an embodiment, the system 400 may include a pressure sensor 412 mounted on an inlet of the RCI unit 106 and in communication with the control unit 402. The pressure sensor 412 may be embodied as a low-pressure switch 412 as shown in Figure 5. Herein, the pressure sensor 412 may be adapted to determine the pressure supplied to the RCI unit 106 and provide the input signal of the determined pressure to the control unit 402. The control unit 402 may be adapted to actuate the feedback unit to indicate the non-operational state of the RCI unit 106 if the determined pressure is less than the predefined amount of pressure. Herein, the buzzer 414 may be referred to as a pressure indication switch 414 adapted to notify the driver about a pressure drop.

The low-pressure switch 412 may be adapted to connect the pressure indication switch 414 with the RCI unit 106 and the ECU 402. The ECU 402 may generate the feedback signal in case of a pressure drop less than the predetermined pressure. Further, the feedback signal from low-pressure switch 412 may be used as an input for the buzzer 414 to indicate to the driver about the state of the RCI unit 106. In an embodiment, the warning lamp 408 and the buzzer 414 may be installed on the dashboard of the vehicle 100 to generate indications for the driver. Herein, the warning lamp 408 may be adapted to indicate to the driver that the RCI unit 106 is non-operational state due to non-supply of power from the ECU 402. The buzzer 414 may be adapted to notify the driver that there is the pressure drop in the vehicle 100.

The system 400 of the present disclosure, may include the indication device 408 and 414 that indicates the driver about the operational state of the RCI unit 106. The indication device 408 and 414 may be installed on the dashboard, such that the driver may identify whether the RCI unit 106 is in the operational state or in the non-operational state, just by looking at the indication device 408, 414. In such conditions, the driver shall be aware of the working of the RCI unit 106, and the driver shall not directly shift the gears from the high range to the low range without lowering the speed of the vehicle 100. This prevents the shifting of gears which leads to damage in planetary gear shifting assembly of the vehicle 100 due to rapid engagement and disengagement, so that the overall maintenance cost associated with the repair of gearbox is reduced. In addition, the implementation of the system 400 may reduce the accidents of the vehicle 100 due to the structural failure of the gearbox, as the structural failure of the gearbox may be prevented.

While specific language has been used to describe the present subject matter, any limitations arising on account thereto, are not intended. As would be apparent to a person in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein. The drawings and the foregoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment. ,CLAIMS:1.
