[0047] In the following description, exemplary embodiments of the present invention will be described with reference to the accompanying drawings and exemplary embodiments. For descriptive purposes, the proportions of the components shown in the drawings differ from the actual proportions, and therefore the proportions are not limited to those shown in the drawings.
[0048] Figure 1 This is a block diagram illustrating a braking system according to an embodiment.
[0049] Reference Figure 1 The braking system 1 may include: brakes 110, 120, 130 and 140, respectively disposed in the wheels w1, w2, w3 and w4 of the vehicle and configured to stop the rotation of the wheels w1, w2, w3 and w4; one or more power supply devices 150 configured to supply power to the braking system 1; and a controller 160 configured to control the braking system 1.
[0050] Brakes 110, 120, 130 and 140 may include: a first brake 110 configured to brake or release a first wheel w1; a second brake 120 configured to brake or release a second wheel w2; a third brake 130 configured to brake or release a third wheel w3; and a fourth brake 140 configured to brake or release a fourth wheel w4.
[0051] For example, the first wheel w1 and the second wheel w2 can be the front wheels, and the third wheel w3 and the fourth wheel w4 can be the rear wheels.
[0052] The first brake 110 and the second brake 120 can be configured as hydraulic brakes that operate by liquid pressure. Therefore, the braking system 1 may also include a liquid pressure supply device (not shown).
[0053] For example, the liquid pressure supply device may include: a reservoir configured to store a pressurized medium; a master cylinder configured to provide a reaction force to the driver corresponding to the pedal force of the brake pedal 31 and to pressurize and discharge the pressurized medium, such as brake fluid, contained therein; a liquid pressure supply unit configured to generate liquid pressure of the pressurized medium by means of mechanical operation by receiving the driver's braking intention as an electrical signal from a pedal displacement sensor 30 configured to detect the displacement of the brake pedal 31; a hydraulic control unit configured to control the liquid pressure from the liquid pressure supply unit; a hydraulic pressure circuit with wheel cylinders configured to brake a first wheel w1 and a second wheel w2 by receiving the liquid pressure of the pressurized medium; a connecting flow path configured to hydraulically connect the master cylinder and the hydraulic pressure circuit; a dump control unit disposed between the liquid pressure supply unit and the reservoir and configured to control the flow of the pressurized medium; a reservoir flow path configured to hydraulically connect the reservoir and the master cylinder; and / or a check flow path connected to the main chamber of the master cylinder.
[0054] The liquid pressure supply device can generate liquid pressure in response to the output signal of the pedal displacement sensor 30, and supply the generated liquid pressure to the wheel cylinders of the first wheel w1 and the second wheel w2 through the transmission flow path, so that braking force can be generated in the first wheel w1 and the second wheel w2 according to the internal pressure of the wheel cylinder.
[0055] Alternatively, the first brake 110 and the second brake 120 can be configured as electromechanical brakes (EMBs) that operate by electromechanical means, i.e., by generating braking force by means of a motor and mechanical components to generate clamping force for braking the respective wheels. The first brake 110 may include a controller (not shown) for controlling the first brake 110, and the second brake 120 may include a controller (not shown) for controlling the second brake 120. Furthermore, one or more force sensors may be provided in each of the first brake 110 and the second brake 120 to detect the clamping force of the respective brake.
[0056] A controller for controlling each of the first brake 110 and the second brake 120 may include drive circuitry for the motor. In response to a control signal from the controller 160, the drive circuitry may operate the motor to generate or eliminate braking force in the respective wheel.
[0057] For example, an electromechanical brake can be a caliper brake or a drum brake.
[0058] A caliper brake may include: a pair of pads mounted to press against a brake disc configured to rotate with each of wheels w1 and w2; a caliper housing configured to operate the pair of pads; a piston mounted in the caliper housing and configured to advance or retract; a power conversion unit configured to receive rotational drive power for moving the piston, convert the rotational drive power into linear drive power, and transmit the linear drive power to the piston; and / or a brake motor configured to generate rotational drive power for moving the piston.
[0059] A drum brake may include: a pair of brake shoes, each having an arcuate shape and mounted to be movable along the surface of a backing plate coupled to the vehicle body; a drum having a friction surface on its inner circumference and configured to rotate with the corresponding wheel of the vehicle; and / or an electric actuator configured to apply force to the brake shoes in the direction in which the pair of brake shoes are deployed. The electric actuator may include a motor, a reducer, and / or a pressurizing mechanism.
[0060] The third brake 130 and the fourth brake 140 may each be provided as electromechanical brakes. The third brake 130 may be referred to as the first electromechanical brake, and the fourth brake 140 may be referred to as the second electromechanical brake.
[0061] The third brake 130 may include a controller 132 configured to control the third brake 130, and the fourth brake 140 may include a controller 142 configured to control the fourth brake 140. Controller 132 may be referred to as a first electromechanical brake controller, and controller 142 may be referred to as a second electromechanical brake controller.
[0062] One or more force sensors 10 may be disposed in the third brake 130, and one or more force sensors 20 may be disposed in the fourth brake 140.
[0063] One or more force sensors 10 may include a first force sensor 11 and / or a second force sensor 12.
[0064] One or more force sensors 20 may include a third force sensor 21 and a fourth force sensor 22.
[0065] The controller 132 of the third brake 130 and the controller 142 of the fourth brake 140 can be electrically or communicatively connected to the controller 160, and perform braking control or brake release control on the third brake 130 and the fourth brake 140 in response to the braking control or brake release control signal of the controller 160.
[0066] One or more force sensors 10 may be electrically or communicatively connected to the controller 132 of the third brake 130.
[0067] Therefore, the controller 132 can receive signals corresponding to the clamping force of the third brake 130 from one or more force sensors 10 and perform feedback control to adjust the clamping force of the third brake 130.
[0068] The controller 132 of the third brake 130 can respond to the output signal of the first force sensor 11 and the output signal of the second force sensor 12 by utilizing the signal correlation analysis function in the prior art to improve the clamping force accuracy of the third brake 130.
[0069] For example, the controller 132 of the third brake 130 can control the third brake 130 based on a comparison between the output signal of the first force sensor 11 and the output signal of the second force sensor 12, that is, to perform feedback control. Since feedback control is a technique in the relevant art, a detailed description of this control will be omitted.
[0070] Furthermore, the controller 132 of the third brake 130 can detect abnormal conditions (e.g., detect an error in either force sensor) by comparing and analyzing the output signals of the first force sensor 11 and the second force sensor 12, thereby performing control to optimize braking performance and maintain the stability of the third brake 130. In other words, the first force sensor 11 and the second force sensor 12 can be redundant. When either force sensor fails, the other force sensor can be used to control the corresponding brake.
[0071] For example, when either the first force sensor 11 or the second force sensor 12 fails to function, the controller 132 of the third brake 130 can control the third brake 130 in response to the output signal of the other force sensor. Since the identification of force sensor malfunction is a technology in the relevant art, its detailed description will be omitted.
[0072] The controller 132 of the third brake 130 can use the first force sensor 11 as the main sensor and the second force sensor 12 as the auxiliary force sensor.
[0073] For example, the controller 132 of the third brake 130 can control the third brake 130 in response to the output signal of the first force sensor 11, i.e., perform feedback control. When it is detected that the first force sensor 11 is not working, the controller 132 of the third brake 130 can control the third brake 130 in response to the output signal of the second force sensor 12. Since the identification of the failure of the force sensor is a technology in the relevant art, its detailed description will be omitted.
[0074] One or more force sensors 20 may be electrically or communicatively connected to the controller 142 of the fourth brake 140. Thus, the controller 142 may receive signals corresponding to the clamping force of the fourth brake 140 from one or more force sensors 20 and perform feedback control to adjust the clamping force of the fourth brake 140.
[0075] The controller 142 of the fourth brake 140 can respond to the output signals of the third force sensor 21 and the fourth force sensor 22 by utilizing the signal correlation analysis function in the prior art to improve the clamping force accuracy of the fourth brake 140.
[0076] For example, the controller 142 of the fourth brake 140 can control the fourth brake 140 based on a comparison between the output signal of the third force sensor 21 and the output signal of the fourth force sensor 22, that is, to perform feedback control.
[0077] Furthermore, the controller 142 of the fourth brake 140 can detect abnormal conditions (e.g., detect an error in either force sensor) by comparing and analyzing the output signals of the third force sensor 21 and the fourth force sensor 22, thereby performing control to optimize braking performance and maintain the stability of the fourth brake 140. In other words, the third force sensor 21 and the fourth force sensor 22 can be redundant. When either force sensor fails, the other force sensor can be used to control the corresponding brake.
[0078] For example, when either the third force sensor 21 or the fourth force sensor 22 fails to function, the controller 142 of the fourth brake 140 can control the fourth brake 140 in response to the output signal of the other force sensor. Since the identification of force sensor malfunction is a technology in the relevant art, its detailed description will be omitted.
[0079] The controller 142 of the fourth brake 140 can use the third force sensor 21 as the main force sensor and the fourth force sensor 22 as the auxiliary force sensor.
[0080] For example, the controller 142 of the fourth brake 140 can control the fourth brake 140 in response to the output signal of the third force sensor 21, i.e., perform feedback control. When it is detected that the third force sensor 21 is not working, the controller 142 of the fourth brake 140 can control the fourth brake 140 in response to the output signal of the fourth force sensor 22. Since the identification of the failure of the force sensor is a technology in the relevant art, its detailed description will be omitted.
[0081] The power supply unit 150 can be configured to supply power to the components of the braking system 1, such as the controller 132 of the third brake 130 and the controller 142 of the fourth brake 140, force sensors 10 and 20, controller 160 and / or pedal displacement sensor 30.
[0082] The power supply device 150 may include a first power supply device 1510 and a second power supply device 1520 and implement power redundancy.
[0083] The first power supply device 1510 and the second power supply device 1520 may include independent power circuits configured to supply power from different batteries, or may include independent power circuits separate from one battery.
[0084] For example, the first power supply device 1510 may include a first battery and / or a first power circuit configured to provide power from the first battery, and the second power supply device 1520 may include a second battery and / or a second power circuit configured to provide power from the second battery. Alternatively, the first power supply device 1510 and the second power supply device 1520 may each include a first power circuit and a second power circuit configured to provide power from a single battery.
[0085] The controller 160 can be electrically or communicatively connected to the pedal displacement sensor 30 of the brake pedal 31.
[0086] The controller 160 can receive the output signal of the pedal displacement sensor 30 and, in response to the output signal of the pedal displacement sensor 30, output a signal for performing braking control or brake release control on the first brake 110, the second brake 120, the third brake 130 and / or the fourth brake 140.
[0087] The pedal displacement sensor 30 can output a signal corresponding to the displacement (e.g., distance traveled and / or speed of travel) of the brake pedal 31. Therefore, the controller 160 can identify the displacement of the brake pedal 31 in response to the output signal of the pedal displacement sensor 30, and thus output a brake control signal corresponding to the driver's braking intention.
[0088] Controller 160 may include a first controller 1610 and / or a second controller 1620.
[0089] For example, the first controller 1610 may be the basic controller of the braking system 1, and the second controller 1620 may be a backup controller.
[0090] For example, the first controller 1610 can control the first brake 110, the second brake 120, the third brake 130, and the fourth brake 140, and the second controller 1620 can control the first brake 110, the second brake 120, the third brake 130, and the fourth brake 140. In this case, the first controller 1610 can be the basic controller of the braking system 1, the second controller 1620 can be a backup controller, and the second controller 1620 can operate if the first controller 1610 fails or cannot operate.
[0091] As another example, the first controller 1610 can control the first brake 110 and the second brake 120, and control either the third brake 130 or the fourth brake 140. The second controller 1620 can control the first brake 110 and the second brake 120, and control the remaining brake among the third brake 130 and the fourth brake 140 that is not controlled by the first controller 1610. In this case, with the first brake 110 and the second brake 120, the first controller 1610 can be the primary controller, and the second controller 1620 can be the backup controller. Therefore, in the event of a failure or inoperability of the first controller 1610, the second controller 1620 can control the first brake 110 and the second brake 120, and control the remaining brake among the third brake 130 and the fourth brake 140, which is a brake that is not controlled by the first controller 1610 when no failure occurs.
[0092] As another example, the first controller 1610 can control the first brake 110 and the fourth brake 140, and the second controller 1620 can control the second brake 120 and the third brake 130.
[0093] The first controller 1610 may include a processor 1611 and a memory 1613.
[0094] The processor 1611 can process the output signal of the pedal displacement sensor 30 and, in response to the output signal of the pedal displacement sensor 30, output a control signal for performing braking control on the first brake 110, the second brake 120, the third brake 130 and the fourth brake 140.
[0095] The memory 1613 can store or remember programs and data used to control the operation of components included in the braking system 1. The memory 1613 can provide the stored programs and data to the processor 1611, and store temporary data generated during the operation of the processor 1611.
[0096] The second controller 1620 may include a processor 1621 and a memory 1623.
[0097] The processor 1621 can process the output signal of the pedal displacement sensor 30 and, in response to the output signal of the pedal displacement sensor 30, output a control signal for performing braking control on the first brake 110, the second brake 120, the third brake 130 and the fourth brake 140.
[0098] The memory 1623 can store or remember programs and data used to control the operation of components included in the braking system 1. The memory 1623 can provide the stored programs and data to the processor 1621, and also store temporary data generated during the operation of the processor 1621.
[0099] Memory 1613 and memory 1623 may each include volatile memory, such as static random access memory (S-RAM) and dynamic random access memory (D-RAM), and non-volatile memory, such as read-only memory (ROM), erasable programmable read-only memory (EEPROM), electrically erasable programmable read-only memory (EEPROM), and flash memory.
[0100] The first controller 1610 and the second controller 1620 may each include one or more semiconductor elements and are referred to by various terms such as electronic control unit (ECU).

[0103] The braking system 1-1 may include: a first brake 110 and a second brake 120, which are caliper-type hydraulic brakes; a third brake 130 and a fourth brake 140, which are drum-type electromechanical brakes; a first force sensor 11 and a second force sensor 12 disposed in the third brake 130; a third force sensor 21 and a fourth force sensor 22 disposed in the fourth brake 140; a first battery 1510 and a second battery 1520, the first battery 1510 corresponding to a first power supply device 1510 and the second battery 1520 corresponding to a second power supply device 1520, the first power supply device and the second power supply device being two independent power supply devices; a controller 160 configured to control at least one component of the braking system 1-1; a liquid pressure supply device 190 configured to provide liquid pressure to the first brake 110 and the second brake 120; and a pressure sensor 40 capable of measuring the liquid pressure of the pressurized medium when the first brake 110 and the second brake 120 are operated by the pedal displacement sensor 30 of the brake pedal 31 and / or the liquid pressure supply device 190.
[0104] The third brake 130 may include a controller 132, and the fourth brake 140 may include a controller 142.
[0105] The first brake 110 and the second brake 120 can be hydraulically connected to the liquid pressure supply device 190, and generate braking force on the corresponding wheels w1 and w2, or release the generation of braking force, by receiving liquid pressure from the liquid pressure supply device 190.
[0106] The liquid pressure supply device 190 can be electrically or communicatively connected to the controller 160 and operates by receiving control signals from the controller 160.

Furthermore, when either the first force sensor 11 or the second force sensor 12 fails, the controller 132 can use the remaining force sensor to control the third brake 130.
[0112] Alternatively, controller 132 can perform feedback control on the third brake 130 by using the first force sensor 11 as the primary sensor and the second force sensor 12 as the auxiliary force sensor. For example, controller 132 can control the third brake 130 in response to the output signal of the first force sensor 11. When it is detected that the first force sensor 11 is not working, controller 132 can control the third brake 130 in response to the output signal of the second force sensor 12.
[0113] The dual-type third force sensor 21 and fourth force sensor 22 disposed in the fourth brake 140 can be electrically or communicatively connected to the fourth brake 140. For example, the third force sensor 21 and fourth force sensor 22 can be electrically or communicatively connected to the controller 142 of the fourth brake 140.
[0114] The controller 142 of the fourth brake 140 can perform braking control or brake release control on the fourth brake 140 in response to a control signal from the controller 160.
[0115] Furthermore, the controller 142 can perform signal correlation analysis and / or feedback control in response to the output signals of the third force sensor 21 and the fourth force sensor 22. Additionally, if either the third force sensor 21 or the fourth force sensor 22 fails, the controller 142 can utilize the remaining force sensor to control the fourth brake 140.
[0116] Alternatively, controller 142 can perform feedback control on the fourth brake 140 by using the third force sensor 21 as the primary sensor and the fourth force sensor 22 as the auxiliary force sensor. For example, controller 142 can control the fourth brake 140 in response to the output signal of the third force sensor 21. When it is detected that the third force sensor 21 is not working, controller 142 can control the fourth brake 140 in response to the output signal of the fourth force sensor 22.

[0123] For example, the pedal displacement sensor 30 and the pressure sensor 40 can serve as redundancy for each other, so that if one sensor fails, the other sensor can provide a backup for the function.
[0124] Although not shown in the attached diagram, in Figure 2 In the above embodiments, the third brake 130 and the fourth brake 140, that is, the controller 132 of the third brake 130 and the controller 142 of the fourth brake 140, can be electrically connected or communicatively connected to each other and work together.
[0125] In addition, according to Figure 2In the above configuration of the braking system 1-1, the two force sensors in each of the third brake 130 and the fourth brake 140 are redundant, so that when any one force sensor fails, the remaining force sensor can be used to control the corresponding brake.
