[0010] In a braking system of a two-wheeled vehicle, for example, an electric two-wheeled vehicle, generally two brake levers are present. The brake lever is an operating means that can actuate a wheel braking unit of a braking system. One brake lever is for actuating a rear wheel braking unit and another brake lever is for actuating a front wheel braking unit. Since the two brake levers are independent from each other, the application of brake forces on the front wheel braking unit and the rear wheel braking unit are completely independent from each other. Such an independent braking of the front wheel and the rear wheel is dangerous for a rider of the two-wheeled vehicle. For example, if the two-wheeled vehicle is cruising at a high speed, such as 70 Km / Hour and the rider actuates the brake lever connected to the front wheel braking unit, the two-wheeled vehicle may experience a roll-over and the rider may get injured. Also, the two-wheeled vehicle may also get damaged due to such a roll-over.

[0011] In addition, such a braking system includes additional components that connect the front wheel braking unit and the rear wheel braking unit to the respective brake levers, thereby making the overall braking system complex. Also, the additional components add to the overall weight of the two-wheeled vehicle and to the overall cost of manufacturing of the twowheeled vehicle.

[0012] The present subject matter describes example braking systems for an electric two-wheeled vehicle and electric two-wheeled vehicles having such a braking system. In the example braking systems described herein, safety of a rider of a two-wheeled vehicle and the two-wheeled vehicle itself isensured by simultaneously actuating a front wheel braking unit and a rear wheel braking unit of the two-wheeled vehicle.

[0013] The braking system of a two-wheeled vehicle includes a front brake and a rear brake. The front brake is a brake that, when actuated, deaccelerate a front wheel of the two-wheeled vehicle. The rear brake is a brake that, when actuated, deaccelerate a rear wheel of the two-wheeled vehicle. In an example, the two-wheeled vehicle is an electric two-wheeled vehicle. The front brake is connected to a front wheel of the electric twowheeled vehicle. The rear brake is connected to a rear wheel of the electric two-wheeled vehicle. Further, the braking system includes a brake lever operably coupled to the front brake and the rear brake. The brake lever is an operating means manually actuatable by a rider of the two-wheeled vehicle either by foot or by hand. The braking system further includes a control unit communicatively coupled to the front wheel and the rear wheel. In an example, the control unit is to determine speed related data of the front wheel and the rear wheel.

[0014] Upon actuation of the brake lever, i.e., when the rider actuates the brake lever to stop or to de-accelerate the two-wheeled vehicle, the control unit determines a rate of deceleration of the front wheel and the rear wheel. Based on the determination of the rate of deceleration of the front wheel and the rear wheel, the control unit determines how much braking force is required for the front wheel and for the rear wheel for optimal stopping / de-acceleration of the two-wheeled vehicle. Further, in response to the determination, the control unit adjusts a proportion of the braking force for being applied on each of the front wheel and the rear wheel so that the two-wheeled vehicle is optimally stopped / de-accelerated without compromising the safety of the rider and the two-wheeled vehicle. In an example, the control unit may split the braking force into half for being applied on each of the front wheel and the rearwheel. In an example, the control unit may split the braking force into variable percentage for being applied on each of the front wheel and the rear wheel.

[0015] Accordingly, a single brake lever connected both to the front brake and the rear brake is capable of distributing the braking force to the front wheel and the rear wheel. Thus, an operation load of the rider is reduced, which would have been there in the case where the rider has to actuate separate brake levers for the front wheel and the rear wheel. Since the control unit adjusts the proportion of the braking force for being applied on each of the front wheel and the rear wheel, both the rider and the two-wheeled vehicle are safe from the risk of any accident due to inappropriate application of the braking force on the wheels of the two-wheeled vehicle.

[0016] In addition, provision of a single a brake lever reduces the number of components, which would have otherwise required in case of two brake levers for connecting the front wheel braking unit and the rear wheel braking unit to the respective brake levers. Thus, the reduced number of components makes the overall braking system simple in construction. Also, the reduced number of components makes the braking system light weight and reduces the overall cost of manufacturing of the two-wheeled vehicle.

[0017] The present subject matter is further described with reference to the accompanying figures. Wherever possible, the same reference numerals are used in the figures and the following description to refer to the same or similar parts. It should be noted that the description and figures merely illustrate principles of the present subject matter. It is thus understood that various arrangements may be devised that, although not explicitly described or shown herein, encompass the principles of the present subject matter. Moreover, all statements herein reciting principles, aspects, and examples of the present subject matter, as well as specific examples thereof, are intended to encompass equivalents thereof.

[0018] The manner in which the methods and computing devices are implemented are explained in detail with respect to FIGS. 1 -7. While aspects of described methods and computing devices can be implemented in any number of different devices, environments, and / or implementations, the examples are described in the context of the following system(s). It is to be noted that drawings of the present subject matter shown here are for illustrative purposes and are not drawn to scale.

[0019] FIG. 1 illustrates a block diagram of a braking system 100 for a two-wheeled vehicle (not shown), according to an example. In an example, the two-wheeled vehicle may be an electric two-wheeled vehicle. In an example, the two-wheeled vehicle may be any saddle-type two-wheeled vehicle. The two-wheeled vehicle includes a front wheel 102 and a rear wheel 104. The braking system 100 further includes a front brake 106 connected to the front wheel 102 and a rear brake 108 connected to the rear wheel 104. The front brake 106 is a brake that de-accelerate the front wheel 102 when actuated by the rider of the two-wheeled vehicle. In an example, the front brake 106 is one of a disc brake and a drum brake. The disc brake is a type of brake that uses callipers to squeeze pairs of pads against a disc or a rotor attached to the wheel to create friction for providing braking force to the wheel. The drum brake is a type of brake that uses friction caused by a set of shoes or pads that press outward against a rotating cylinder-shaped part called a brake drum. The rear brake 108 is a brake that de-accelerate the rear wheel 104 when actuated by the rider of the two-wheeled vehicle. In an example, the rear brake 108 is one of a disc brake and a drum brake. Any combination of the types of the brakes is possible in the two-wheeled vehicle. For example, a disc brake as the rear brake and a drum brake as the front brake or a disc brake as the rear brake and another disc brake as the front brake. In an example, one of the front brake 106 and the rear brake 108 is a drum brake. In an example, the front brake 106and the rear brake 108 are a disc brake. In an example, the front brake 106 and the rear brake 108 are a drum brake.

[0020] Further, the braking system 100 includes a brake lever 110 connected to the front brake 106 and the rear brake 108. The brake lever 110 is an operating means actuatable by the rider of the two-wheeled vehicle for de-accelerating the two-wheeled vehicle. In an example, the brake lever 110 is positionable in one of a front left, a front right, a bottom left, and a bottom right position of the two-wheeled vehicle, preferably electric two-wheeled vehicle. In an example, the brake lever 1 10 is operable by one of a hand and a foot of a rider of the two-wheeled vehicle, preferably electric two-wheeled vehicle. For example, if the brake lever 110 is positionable in one of a front left and a front right position of the two-wheeled vehicle, the brake lever 110 is operable by the hand of the rider. In case the brake lever 110 is positionable in one of a bottom left and a bottom right position of the two-wheeled vehicle, the brake lever 110 is operable by the foot of the rider.

[0021] The brake lever 110 is connected to a master cylinder 112 disposed between the brake lever 110 and the front brake 106 and the rear brake 108. The master cylinder 112 is to convert the pressure on the brake lever 110 to hydraulic pressure by feeding brake fluid into a brake circuit and are used both in disc brakes and drum brakes. When the rider actuates the brake lever 110 by applying pressure on the brake lever 110 either by the hand or by the foot, the master cylinder 112 accordingly translates the applied pressure to the front brake 106 and the rear brake 108 via hydraulic pressure and as a result thereof the the two-wheeled vehicle starts de-accelerating.

[0022] Further, the braking system 100 includes a front speed sensor 1 14 connected to the front wheel 102. The front speed sensor 114 is to monitor the speed of the front wheel 102. For example, the front speed sensor 114 is to monitor the revolution per minute (RPM) of the front wheel 102. The brakingsystem 100 also includes a rear speed sensor 116 connected to the rear wheel 104. The rear speed sensor 116 is to monitor the speed of the rear wheel 104. For example, the rear speed sensor 116 is to monitor the revolution per minute (RPM) of the rear wheel 104.

[0023] Further, the braking system 100 includes a control unit 118 connected to the front speed sensor 114 and the rear speed sensor 116. The control unit 118 is explained in detail in FIG. 2, which illustrates a block diagram of the control unit 118 of the braking system 100, according to an example. The control unit 118 may be a computing system found in a wide range of electronic device types to process signals and / or states representative of a diverse of content types for a variety of purposes. Examples of the control unit 118 may include, but are not limited to, an electronic control unit and a vehicle control unit.

[0024] The control unit 118 includes a processor 202. The processor 202 may include microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, state machines, logic circuitries, and / or any other devices that manipulate signals and data based on computer- readable instructions. Further, functions of the various elements shown in the figures, including any functional blocks labelled as “processor(s)”, may be provided through the use of dedicated hardware as well as hardware capable of executing computer-readable instructions.

[0025] Further, the control unit 118 includes a storage device 204. The storage device 204 may include any non-transitory computer-readable medium including, for example, volatile memory, such as static random-access memory (SRAM) and dynamic random-access memory (DRAM), and / or non-volatile memory, such as read only memory (ROM), erasable programmable ROM, flash memories, hard disks, optical disks, and magnetic tapes. The storage device 204 may store an activity data 206. In an example, the activity data 206includes speeds of the front wheel, speed of the rear wheel, pressure value applied by the rider on the brake lever, and predefined thresholds.

[0026] In an example, the control unit 118 includes interface(s) 208. The interface(s) 208 may include a variety of interfaces, for example, interface(s) 208 for users. The interface(s) 208 may include data output devices. The interface(s) 208 may facilitate the communication of the control unit 118 with various communication and electronic devices. In an example, the interface(s) 208 may enable wireless communications between the control unit 118, such as an electronic control unit, and one or more other computing devices (not shown).

[0027] Returning to FIG. 1 , the braking system 100 includes a proportion control valve 120. The proportion control valve 120 is coupled to the control unit 118. The proportion control valve 120 is disposed to regulate amount of pressure being applied on each of the front wheel 102 and the rear wheel, 104 based on the proportion of the braking force to be applied on each of the front wheel 102 and the rear wheel 104. In an example, the proportion of the braking force between the front wheel 102 and the rear wheel 104 is variable. The proportion control valve 120 controls the brake fluid flow rate from the master cylinder 112 by varying the size of the flow passage via a restrictor (not shown). The regulated flow rate subsequently regulates amount of pressure being applied on each of the front wheel 102 and the rear wheel, 104 based on the proportion of the braking force to be applied on each of the front wheel 102 and the rear wheel 104. In an example, a solenoid (not shown) may be disposed between the proportion control valve 120 and the control unit 118 to regulate the proportion control valve 120 based on the data received from the control unit 118.

[0028] In an example, when the rider actuates the brake lever 110 for de-accelerating the two-wheeled vehicle by applying a specified pressure onthe brake lever 110 either by the hand or by the foot, the master cylinder 112, based on the specified pressure, further supplies brake fluid to the front brake 106 to de-accelerate the front wheel 102 and to the rear brake 108 to deaccelerate the rear wheel 104. At the same time, the front speed sensor 114 monitors the speed of the front wheel 102 and the rear speed sensor 1 16 monitors the speed of the rear wheel 104, if the speed of the front wheel 102 is equal to or above a predefined threshold, in an example, 1000 RPM, the control unit 118 regulates the proportion control valve 120 in such a manner that a greater extent of the braking pressure is applied on the rear wheel 104 as compared to the front wheel 102 to avoid any roll-over of the two-wheeled vehicle due to front wheel braking at high speed, i.e., 1000 RPM in an example. In another scenario, if the speed of the rear wheel 104 is below a predefined threshold, in an example, 500 RPM, the control unit 118 regulates the proportion control valve 120 in such a manner that a greater extent of the braking pressure is applied on the front wheel 102 as compared to the rear wheel 104 for smooth de-acceleration of the two-wheeled vehicle.

[0029] The control unit 1 18 is communicatively coupled to the front wheel 102 and the rear wheel 104 via the front speed sensor 114 and the rear speed sensor 116, respectively, to continuously gather data from the sensors 1 14, 116. Upon actuation of the brake lever 110, the control unit 118 determines a rate of deceleration of the front wheel 102 and the rear wheel 104 based on the speed data received from the front speed sensor 114 and the rear speed sensor 116. The control unit 118 accordingly adjusts a proportion of the braking force for being applied on each of the front wheel 102 and the rear wheel 104 in response to the determination by regulating the proportion control valve 118. In an example, the proportion control valve 120 is solenoid based. Other types of the proportion control valve 120 are also feasible.

[0030] In FIG. 3, the front brake 106 is a disc brake and the rear brake 108 is a drum brake. FIG. 3 illustrates a block diagram of the braking system 100 having a front disc brake 302 and a rear drum brake 304, according to an example. The operation of the braking system 100 shown in FIG. 3 is similar to that of explained in FIG. 1. In this case, the proportion control valve 120 regulates a mechanical wire (not shown) connecting the rear drum brake 304 to the brake lever 110 and a calliper (now shown) connecting the front disc brake 302 to the brake lever 110 for adjusting the proportion of the braking force for being applied on each of the front wheel 102 and the rear wheel 104 in response to the determination of the control unit 118 by regulating the proportion control valve 120.

[0031] In FIG. 4, the front brake 106 is a disc brake and the rear brake 108 is another drum brake. FIG. 4 illustrates a block diagram of the braking system 100 having a front disc brake 402 and a rear disc brake 404, according to an example The operation of the braking system 100 shown in FIG. 4 is similar to that of explained in FIG. 1. In this case, the proportion control valve 120 regulates a front calliper (now shown) connecting the front disc brake 402 to the brake lever 110 and a rear calliper (now shown) connecting the rear disc brake 404 to the brake lever 110 for adjusting the proportion of the braking force for being applied on each of the front wheel 102 and the rear wheel 104 in response to the determination of the control unit 118 by regulating the proportion control valve 120.

[0032] In an example, the control unit 118 may command the solenoid to adjust the proportion control valve 120 to achieve a variable front to rear braking force based on the vehicle speed determined by the sensors 114, 1 16.

[0033] FIG. 5 illustrates a block diagram of a braking system 500 providing an equal split of braking force at a front wheel 502 and a rear wheel 504 of a two-wheeled vehicle, according to an example. In an example, thetwo-wheeled vehicle is an electric two-wheeled vehicle. The braking system 500 includes a brake lever 506 similar to the brake lever 1 10 of FIG. 1 and a master cylinder 508 similar to the master cylinder 1 12 of FIG. 1. Further, the braking system 500 includes a front brake 510 similar to the front brake 106 of FIG. 1 and is connected to the front wheel 502. The braking system 500 includes a rear brake 512 similar to the rear brake 108 of FIG. 1 and is connected to the rear wheel 504.

[0034] When the rider actuates the brake lever 506 for de-accelerating the two-wheeled vehicle by applying a specified pressure on the brake lever 506 either by the hand or by the foot, the master cylinder 508 splits the pressure and supplies equal amounts of brake fluid to the front brake 510 to deaccelerate the front wheel 502 and to the rear brake 512 to de-accelerate the rear wheel 504.

[0035] FIG. 6 illustrates a block diagram of a braking system 600 for a two-wheeled vehicle (not shown) having a front drum brake 602 and a rear drum brake 604, according to an example. In an example, the two-wheeled vehicle may be an electric two-wheeled vehicle. In an example, the twowheeled vehicle may be any saddle-type two-wheeled vehicle. The twowheeled vehicle includes a front wheel 606 and a rear wheel 608. The front drum brake 602 of the braking system 600 is connected to the front wheel 606 and the rear drum brake 604 is connected to the rear wheel 608. The front drum brake 602 is a brake that de-accelerate the front wheel 606 when actuated by the rider of the two-wheeled vehicle. The rear drum brake 604 is a brake that de-accelerate the rear wheel 608 when actuated by the rider of the two-wheeled vehicle.

[0036] Further, the braking system 600 includes a brake lever 610 connected to the front drum brake 602 and the rear drum brake 604. The brake lever 610 is an operating means actuatable by the rider of the two-wheeledvehicle for de-accelerating the two-wheeled vehicle. In an example, the brake lever 610 is positionable in one of a front left, a front right, a bottom left, and a bottom right position of the two-wheeled vehicle, preferably electric twowheeled vehicle. In an example, the brake lever 610 is operable by one of a hand and a foot of a rider of the two-wheeled vehicle, preferably electric twowheeled vehicle. For example, if the brake lever 610 is positionable in one of a front left and a front right position of the two-wheeled vehicle, the brake lever 610 is operable by the hand of the rider. In case the brake lever 610 is positionable in one of a bottom left and a bottom right position of the twowheeled vehicle, the brake lever 610 is operable by the foot of the rider.

[0037] The braking system 600 includes a pulley arrangement 612. pulley arrangement 612 is to create a tension between the brake lever 610 and the drum brakes (the front drum brake 602 and the rear drum brake 604) for de-accelerating the two-wheeled vehicle. The brake lever 610 is connected to the pulley arrangement 612 disposed between the brake lever 610 and the front drum brake 602 and the rear drum brake 604. The pulley arrangement 612 is exclusively used in the drum brakes. When the rider actuates the brake lever 610 by applying pressure on the brake lever 610 either by the hand or by the foot, the pulley arrangement 612 accordingly pulls the shoes pads of the front drum brake 602 and the rear drum brake 604 and as a result thereof the the two-wheeled vehicle starts de-accelerating.

[0038] Further, the braking system 600 includes a front speed sensor 614 connected to the front wheel 606. The front speed sensor 614 is to monitor the speed of the front wheel 606. For example, the front speed sensor 614 is to monitor the revolution per minute (RPM) of the front wheel 606. The braking system 600 also includes a rear speed sensor 616 connected to the rear wheel 608. The rear speed sensor 616 is to monitor the speed of the rear wheel 608.For example, the rear speed sensor 616 is to monitor the revolution per minute (RPM) of the rear wheel 608.

[0039] Further, the braking system 600 includes a control unit 618 connected to the front speed sensor 614 and the rear speed sensor 616. The control unit 618 is similar to the control unit 118 and is explained in detail in FIG. 2.

[0040] The pulley arrangement 612 is coupled to the control unit 618 and is to create tension between the brake lever 610 and each of the front wheel 606 and the rear wheel 608, based on the proportion of the braking force to be applied on each of the front wheel 606 and the rear wheel 608. The pulley arrangement 612 is disposed to regulate amount of tension being applied on each of the front wheel 606 and the rear wheel 608. In an example, the proportion of the braking force between the front wheel 606 and the rear wheel 608 is variable. For example, the pulley arrangement 612 may split the tension between the brake lever 610 and each of the front wheel 606 and the rear wheel 608 in 30% and 70%. That is, 30% of tension is applied at the front drum brake 602 and 70% of tension is applied at the rear drum brake 604 by the pulley arrangement 612 based on the commend received from the control unit 618.

[0041] In an example, a solenoid (not shown) may be disposed between the pulley arrangement 612 and the control unit 618 to regulate the pulley arrangement 612 based on the data received from the control unit 618.

[0042] In an example, when the rider actuates the brake lever 610 for de-accelerating the two-wheeled vehicle by applying a specified pressure on the brake lever 610 either by the hand or by the foot, the pulley arrangement 612, based on the specified pressure, further creates the tension between the brake lever 610 and the front and rear drum brakes 602, 604 to de-acceleratethe front wheel 606 and the rear wheel 608. The tension between the brake lever 610 and the front and rear drum brakes 602, 604 is created with equal split. At the same time, the front speed sensor 614 monitors the speed of the front wheel 606 and the rear speed sensor 616 monitors the speed of the rear wheel 608, if the speed of the front wheel 606 is equal to or above a predefined threshold, in an example, 1000 RPM, the control unit 618 regulates the pulley arrangement 612 in such a manner that a greater extent of the tension (for example, 70%) is applied on the rear wheel 608 as compared to the front wheel 606 to avoid any roll-over of the two-wheeled vehicle due to front wheel braking at high speed, i.e., 1000 RPM in an example. In another scenario, if the speed of the rear wheel 608 is below a predefined threshold, in an example, 500 RPM, the control unit 618 regulates the pulley arrangement 612 in such a manner that a greater extent of the braking pressure is applied on the front wheel 606 as compared to the rear wheel 608 for smooth de-acceleration of the twowheeled vehicle.

[0043] The control unit 1 18 is communicatively coupled to the front wheel 606 and the rear wheel 608 via the front speed sensor 614 and the rear speed sensor 616, respectively, to continuously gather data from the sensors 1 14, 116. Upon actuation of the brake lever 610, the control unit 618 determines a rate of deceleration of the front wheel 606 and the rear wheel 608 based on the speed data received from the front speed sensor 614 and the rear speed sensor 616. The control unit 618 accordingly adjusts a proportion of the tension for being applied on each of the front wheel 606 and the rear wheel 608 in response to the determination by regulating the pulley arrangement 612.

[0044] FIG. 7 illustrates a block diagram of a braking system 700 providing an equal split of braking force at a front drum brake 702 and a rear drum brake 704 of a two-wheeled vehicle, according to an example. In anexample, the two-wheeled vehicle is an electric two-wheeled vehicle. The braking system 700 includes a brake lever 706 similar to the brake lever 610 of FIG. 6. Further, the front drum brake 702 is similar to the front drum brake 602 of FIG. 6 and is connected to a front wheel 708 of the two-wheeled vehicle. The rear drum brake 704 similar to the rear drum brake 604 of FIG. 6 and is connected to a rear wheel 710 of the two-wheeled vehicle. The brake lever 706 is connected to the front drum brake 702 and the rear drum brake 704 with a 50%-50% split brake wire (not shown). When the rider actuates the brake lever 706 for de-accelerating the two-wheeled vehicle by applying a specified pressure on the brake lever 706 either by the hand or by the foot, the 50%-50% split brake wire splits the tension in equal magnitude to de-accelerate the twowheeled vehicle.
