Description

Technical Field

[0001] The present application relates to the technical field of vehicle braking systems, and in particular to an integrated electronic parking redundancy system. Background Art

[0002] Motor vehicle parking system refers to a series of equipment and technologies used to fix and park motor vehicles. Its main function is to ensure that the vehicle remains stable when parked, prevent accidental sliding or shifting, and facilitate the driver's operation when parking. Motor vehicle parking systems usually include parking brakes, wheel locking devices and suspension systems. Among them, parking brakes can include mechanical parking brakes, electronically controlled parking brakes, automatic parking systems, and anti-skid parking devices. Motor vehicle parking systems are an indispensable part of modern vehicles, ensuring the basic function of safe parking of vehicles. From traditional manual handbrakes to modern intelligent electronic control systems, the technology of parking systems continues to evolve to meet the growing needs for safety and convenience. With the advent of the era of autonomous driving and electrification, motor vehicle parking systems are likely to achieve a higher level of intelligence and automation.

[0003] In the related technology, the electronic parking system (EPB) realizes parking brake through electronic control technology, replacing the traditional mechanical lever and cable structure. When the EPB caliper is working, the motor drives the gear or screw to push the brake pad to apply force to the brake disc to complete the braking process. According to the standard, for vehicles equipped with EPB, when the wiring harness (except the power supply line) or the control bridge fails, the vehicle needs to still be able to park fully loaded on a slope with a slope of 8%. In conventional solutions, the P gear lock is usually used to meet the requirements of the standard. For vehicles equipped with a parking gear locking mechanism, when the vehicle is in the P gear, the internal locking mechanism locks the gearbox to assist the vehicle in parking.

[0048] This application is made by the inventor based on the recognition and research of the following issues, specifically:

[0049] In the related technology, the electronic parking system (EPB) realizes parking brake through electronic control technology, replacing the traditional mechanical lever and cable structure. When the EPB caliper is working, the motor drives the gear or screw to push the brake pad to apply force to the brake disc to complete the braking process. According to the standard, for vehicles equipped with EPB, when the wiring harness (except the power supply line) or the control bridge fails, the vehicle needs to still be able to park fully loaded on a slope with a slope of 8%. In conventional solutions, the P gear lock is usually used to meet the requirements of the standard. For vehicles equipped with a parking gear locking mechanism, when the vehicle is in the P gear, the internal locking mechanism locks the gearbox to assist the vehicle in parking.

[0050] However, the current electronic parking system has the following technical problems:

[0051] The existing electronic parking system is difficult to meet the requirements of the standards, and there is still much room for optimization.

[0052] Based on this, the embodiment of the present application provides an integrated electronic parking redundancy system. Figure 1 and Figure 2 shown. Figure 1 FIG. 4 shows a schematic diagram of the system structure of an integrated electronic parking redundancy system in an embodiment of the present application. Figure 2 The connection diagram of the integrated electronic parking redundancy system with single-side dual control in one embodiment of the present application is shown in FIG. The embodiment of the present application provides an integrated electronic parking redundancy system, including a main control module 100, a redundant control module 200, a sensing module 300 and a braking module 400, wherein:

[0053] The main control module 100 is used to output a first parking instruction based on a preset main control logic to implement parking control of the electronic parking redundancy system;

[0054] The redundant control module 200 is used to output a second parking instruction based on a preset redundant control logic to implement the parking control of the electronic parking redundant system;

[0055] The sensing module 300 is connected to the main control module 100 and the redundant control module 200, and is used to monitor the preset functional modules of the target vehicle system to obtain a parking trigger signal;

[0056] The braking module 400 is connected to the main control module 100 and the redundant control module 200. The braking module 400 is used to perform parking braking on the target vehicle. The braking module 400 is controlled by the main control module 100. When the main control module 100 fails, the braking module 400 is controlled by the redundant control module 200.

[0057] By implementing the above-mentioned integrated electronic parking redundancy system, the following beneficial effects can be achieved:

[0058] An integrated electronic parking redundancy system includes a main control module 100, a redundant control module 200, a sensing module 300 and a braking module 400. The main control module 100 is used to output a first parking instruction based on a preset main control logic to realize the parking control of the electronic parking redundancy system; the redundant control module 200 is used to output a second parking instruction based on a preset redundant control logic to realize the parking control of the electronic parking redundancy system; the sensing module 300 is connected to both the main control module 100 and the redundant control module 200, and is used to monitor the preset functional module of the target vehicle system to obtain a parking trigger signal; the braking module 400 is connected to the main control module 100 and the redundant control module 200, and is used to perform parking brakes on the target vehicle, and the braking module 400 is controlled by the main control module 100. When the main control module 100 fails, the braking module 400 is controlled by the redundant control module 200. In implementation, the system is provided with a main control module 100 and a redundant control module 200, both of which are used to control the brake module 400 to implement parking brake. When the sensing module 300 monitors the preset function module of the target vehicle system and determines the parking trigger signal, it can determine the parking intention of the operator, and then trigger further parking brake. At this time, the main control module 100 can output a first parking instruction based on the preset main control logic, and control the brake module 400 to perform parking brake through the first parking instruction. At this time, if the main control module 100 has an abnormality and causes the control of the brake module 400 to fail, the redundant control module 200 outputs a second parking instruction based on the preset redundant control logic to implement parking brake control of the brake module 400. In this way, the system can still have the ability to control the brake module 400 when the main control unit fails, and ultimately improve the stability of the parking system.

[0059] In one embodiment, the braking module 400 includes:

[0060] A first motor drive unit 401 is connected to the redundant control module 200. The first motor drive unit 401 is controlled by the redundant control module 200 and is used to control the corresponding terminal brake to perform parking braking.

[0061] The second motor drive unit 402 is connected to both the main control module 100 and the redundant control module 200. The second motor drive unit 402 is controlled by the main control module 100 or the redundant control module 200 and is used to control the corresponding terminal brake to perform parking braking.

[0062] In this embodiment, the brake module 400 is provided with a first motor drive unit 401 and a second motor drive unit 402. The two motor drive units form a single-side single-control system architecture, which can improve the stability of the parking brake, improve the braking effect, and enhance the braking force of the parking brake.

[0063] In one embodiment, the system comprises:

[0064] The first instruction switching module 500 is disposed between the second motor drive unit 402 and the main control module 100 and the redundant control module 200 , and is used for switching control of the control instructions output to the second motor drive unit 402 .

[0065] Specifically, the first instruction switching module 500 is disposed between the second motor drive unit 402 and the main control module and the redundant control module 200, and can receive the first parking instruction output by the main control module 100 and the second parking instruction output by the redundant control module 200, and control the second motor drive unit 402. In the scenario where the signal transmission between the main control module 100 and the redundant control module 200 is normal, after the first parking instruction and the second parking instruction are input into the first instruction switching module 500, the first instruction switching module 500 can control the second motor drive unit 402 according to the preset priorities of the first parking instruction and the second parking instruction. For example, when the system status is normal, the main control module 100 can normally control the second motor drive unit 402 and make the vehicle enter the parking state. At this time, the first parking instruction in the first instruction switching module 500 has a higher priority than the second parking instruction. After receiving the first parking instruction and the second parking instruction, the first instruction switching module 500 outputs the first parking instruction; when the main control module 100 communicates normally with the redundant control module 200, but the main control module 100 cannot normally control the second motor drive unit 402 to make the vehicle enter the parking state, at this time, although the first instruction switching module 500 can receive the first parking instruction, a fault occurs during the execution of the first parking instruction, and the sensing module 300 detects that the vehicle has not entered the parking state. The sensing module transmits the sensing signal at this time to the main control module 100 and the redundant control module 2 00, after the first instruction switching module 500 receives any switching signal from the main control module 100 or the redundant control module 200, the priority of the first parking instruction in the first instruction switching module 500 is adjusted to be lower than the second parking instruction. After receiving the first parking instruction and the second parking instruction, the first instruction switching module 500 outputs the second parking instruction; when the system state is abnormal, the communication between the main control module 100 and the redundant control module 200 is abnormal, the main control module 100 cannot normally control the second motor drive unit 402, so that the vehicle enters the parking state, and it is difficult to transmit the priority settings of the first parking instruction and the second parking instruction through signals, at this time, after the first instruction switching module 500 receives the second parking instruction, the first instruction switching module 500 outputs the second parking instruction to control the second motor drive unit 402 to realize parking braking.

[0066] In this embodiment, an instruction switching module is set in the system, and the two control instructions of the main control module 100 and the redundant control module 200 are switched and output through the instruction switching module to form a single-side dual-control redundant control architecture, which helps to improve the stability of system control.

[0067] In one embodiment, the first motor drive unit 401 is also connected to the main control module 100, and the system further includes:

[0068] The second instruction switching module 600 is provided between the first motor drive unit 401 and the main control module 100 and the redundant control module 200 , and is used for switching control of the control instructions output to the first motor drive unit 401 .

[0069] Exemplarily, the functional logic of the second instruction switching module 600 is similar to that of the first instruction switching module 500, and will not be described in detail herein.

[0070] In this embodiment, a second instruction switching module 600 is also provided in the system. By providing two instruction switching modules, two control modules and two braking modules 400, a bilateral dual-control redundant control architecture is implemented, which helps to further improve the stability of the system redundant control.

[0071] In one embodiment, the sensing module 300 includes:

[0072] The brake switch unit 301 is connected to the main control module 100 and is used to obtain the parking trigger signal, which is determined according to the switch state of the brake switch.

[0073] In this embodiment, the sensing module 300 includes a brake switch unit 301, which helps to detect the switch state of the on-board mechanical switch on the target vehicle, thereby obtaining a parking trigger signal, which helps to improve the convenience of vehicle parking control.

[0074] In one embodiment, the sensing module 300 further includes:

[0075] The vehicle communication network unit 302 is connected to the main control module 100 and is used to obtain the parking trigger signal, and the parking trigger signal is determined according to the interactive signal of the vehicle communication network.

[0076] For example, the vehicle communication network unit 302 may include CAN, FlexRay, EtherNet, etc.

[0077] In this embodiment, the sensing module 300 includes a vehicle communication network unit 302, which helps to utilize the vehicle communication network unit 302 on the target vehicle, determine the operator's parking intention through interactive information, and thus obtain a parking trigger signal, which helps to improve the convenience of vehicle parking control.

[0078] In one embodiment, the sensing module 300 further includes:

[0081] In this embodiment, the sensing module 300 is also provided with a wheel speed sensing unit 303, which helps to detect the vehicle state, so as to determine whether the vehicle state meets the requirements of parking braking. The wheel speed detection signal and the parking trigger signal are combined to jointly determine whether to perform parking braking, which helps to improve the safety of the system.

[0082] In one embodiment, the wheel speed sensing unit 303 includes:

[0083] The wheel speed detection devices 3031 are provided in several groups and distributed on different wheels of the target vehicle. The wheel speed detection devices 3031 are connected to the main control module 100 and the redundant control module 200 at the same time.

[0084] In this embodiment, the wheel speed sensing unit 303 includes several groups of wheel speed detection devices 3031, and the wheel speed detection devices 3031 are all connected to the main control module 100 and the redundant control module 200, thereby realizing independent wheel speed detection on each side, which helps to further improve the stability of the system.

[0085] In one embodiment, the system further comprises:

[0086] A connection module 700, which is disposed between the main control module 100 and the redundant control module 200, and is used to implement signal transmission between the main control module 100 and the redundant control module 200;

[0087] The connection module 700 includes a plurality of groups of independent connection units, and the connection units are used to support signal transmission between the main control module 100 and the redundant control module 200 when an abnormality occurs in other connection units.

[0088] Exemplarily, the connection unit includes CAN, SPI, UART, etc. The signal transmitted between the main control module 100 and the redundant control module 200 may include a PWM signal, an analog level, etc.

[0089] In this embodiment, the connection module 700 provided between the main control module 100 and the redundant control module 200 includes a plurality of independent connection units, and the signal transmission in abnormal scenarios is realized through the connection units, which helps to improve the stability of signal transmission.

[0092] The power supply module 800 includes a main power supply unit 801 and a redundant power supply unit 802 .

[0093] In this embodiment, a power supply module 800 is provided to supply power to the main control module 100 and the redundant control module 200, wherein the main power supply unit 801 is connected to the main control module 100, and the redundant power supply unit is connected to the redundant control module 200.
