, Description:TECHNICAL FIELD
[001] The embodiments herein generally relate to braking systems in vehicles and more particularly, to a system and a method for automatic one-side braking in an off-road vehicle such as tractor during turning of the vehicle.

BACKGROUND
[002] Generally, a braking system in a vehicle is used to reduce the speed of the vehicle or to stop the moving vehicle. Typically, off-road vehicles such as tractor include separate left brake pedal and right brake pedal for independently operating the left rear brake unit and right rear brake unit of the vehicle respectively. For example, when the vehicle is intended to make a tight right turn (i.e., to reduce the turn radius of the tractor for a right turn), the right brake pedal is pressed by the operator for activating the right rear brake unit manually whereby the rotational speed of the braked right rear wheel is reduced, thereby reducing the turn radius of the braked right rear wheel by which the turn radius of the tractor is reduced, such that the tractor almost pivots about the right rear wheel. Headland operation in agricultural fields requires frequent braking of the vehicle. The continuous braking of the vehicle by the operator in agricultural fields during field operation may cause fatigue to the operator and in turn may reduce the productivity. The frequent and over pressing of left or right brake pedal by the operator may result in wear and tear of components of the left and/or right rear brake unit.
[003] Therefore, there exists a need for a system and a method for automatic one-side braking in an off-road vehicle during turning of the vehicle, which obviates the aforementioned drawbacks.

Referring now to the drawings Figs. 1 through 3, where similar reference characters denote corresponding features consistently throughout the figures, there are shown embodiments.

For the purpose of this description and ease of understanding, the automatic one-side braking system (100) is explained herein with below reference to automatic one-side braking during turning of off-road vehicle such as tractor. However, it is also within the scope of the invention to use/practice the automatic one-side braking system (100) for automatic one-side braking during turning of any other vehicles without otherwise deterring the intended function of the system (100) as can be deduced from the description and corresponding drawings.
[0021] The one-side braking control switch (104) is in communication with the controller unit (102). The one-side braking control switch (104) can be moved between one of ON condition and OFF condition which is communicated to the controller unit (102). The ON condition of the one-side braking control switch (104) signals the controller unit (102) to perform one-side braking of the vehicle. The OFF condition of the one-side braking control switch (104) signals to the controller unit (102) to deactivate (switch off) one-side braking of the vehicle.
[0022] The left wheel angle sensor (106) is adapted for monitor and communicate wheel angle of corresponding left wheel (LW) of the vehicle to the controller unit (102). The right wheel angle sensor (108) is adapted for monitor and communicate wheel angle of corresponding right wheel (RW) of the vehicle to the controller unit (102).

[0025] The brake latch switch module (112) is in communication with the controller unit (102). The brake latch switch module (112) is moved between one of the open condition and closed condition, which is communicated to the controller unit (102). The open condition of the brake latch switch module (112) signals to the controller unit (102) that left brake pedal and right brake pedal is not connected with each other. The closed condition of the brake latch switch module (112) signals to the controller unit (102) that the left brake pedal and right brake pedal is connected with each other. The controller unit (102) is configured to activate one of the left wheel brake actuator (114) and the right wheel brake actuator (116) to facilitate automatic one-side braking of the vehicle based on inputs received from the one-side braking control switch (104), the wheel angle sensors (106, 108), the speed sensor module (110) and the brake latch switch module (112). For example, the controller unit (102) is configured to activate one of the left wheel brake actuator (114) and the right wheel brake actuator (116) to facilitate one-side braking of the vehicle when the vehicle speed as sensed by the speed sensor module (110) reaches predefined speed threshold, the wheel angle as sensed by wheel angle sensors (106, 108) reaches a predefined wheel angle threshold, the one-side braking control switch (104) is in ON condition and the brake latch switch module (112) is in open condition. For the purpose of this description and ease of understanding, the predefined wheel angle is more than 20 degree and the predefined speed threshold is less than 15 kilometer per hour. It is also within the scope of the invention to vary the predefined wheel angle and predefined speed threshold as per the requirement and design and configuration of the vehicle.

Further, the controller unit (102) is adapted to activate at least one of the left wheel brake actuator (114) and the right wheel brake actuator (116) which in turn varies pressure of brake fluid to left rear brake unit (not shown) and right rear brake unit (not shown) respectively in accordance to the measured angle of brake pedal(s) as sensed and communicated by the brake pedal angle sensors (118, 120) to the controller unit (102).
[0028] The power take off (PTO) lever position sensor (124) is adapted to monitor and communicate engaged position (power take off position) or disengaged position (PTO cut off position) of a power take off (PTO) lever to the controller unit (102).

[0035] Further, the method (200) includes, selecting and communicating, by a brake preset force control member (111), user defined brake preset force to the controller unit (102); and activating, by the controller unit (102), at least one of the left wheel brake actuator (114) and the right wheel brake actuator (116) in a controlled manner to facilitate partial braking or full braking of the vehicle based on input received from said brake preset force control member (111). Furthermore, the method (200) includes, monitoring and communicating, by a power take off (PTO) lever position sensor (124), engaged position (power take off position) or disengaged position (PTO cut off position) of a power take off (PTO) lever to the controller unit (102).
[0036] The technical advantages of the system (100) are as follows. The automatic one-side braking system assists the off-road vehicle to have shorter turning radius. The automatic one-side braking system reduces fatigue to the operator. The automatic one-side braking system achieves better headland operation thereby enhancing the productivity. The automatic one-side braking system enhances the lifetime of the brakes of the vehicle. The automatic one-side braking system assists in one-sided braking of the vehicle in a user defined manner. The automatic braking system maintains the vehicle in auto straight line thereby increasing productivity. The automatic braking system assists in automatic braking during parking thereby preventing accidents. The automatic braking system enhances the safety of operation with implement. The automatic braking system provides comfort and safe brake operation.
