Description

Technical Field

[0001] This invention belongs to the field of automotive crash test technology, and relates to a manual remote control braking system and method in automotive crash tests. Background Technology

[0002] Crash tests are an important method for evaluating vehicle safety performance. During the test, if the vehicle veers to one side or exhibits other abnormal behavior, the test must be stopped immediately and braking measures must be taken to prevent accidental collisions, ensure the validity of the test, and avoid vehicle damage.

[0003] Currently, the commonly used method involves onboard braking systems. These systems use sensors to detect vehicle deceleration and automatically brake, or use a remote emergency stop switch for manual braking. The system utilizes air pressure as a power source, transmitting braking pressure from the master cylinder to the wheel cylinders via brake fluid, ensuring a rapid response and precise stopping control in critical moments. However, these onboard braking systems generally suffer from high cost and large size, especially noticeable in scenarios with high testing frequency. Furthermore, the large size of the equipment makes moving and transporting it between test sites inconvenient, increasing the time and labor costs for test preparation and follow-up. Due to cost and size constraints, onboard braking systems are often not equipped in low-speed or low-risk collision tests, increasing potential accident hazards in these tests. Summary of the Invention

[0004] The purpose of this invention is to provide a manual remote control braking system and method for automobile crash tests, so as to solve the technical problem of large size of vehicle-mounted braking equipment.

[0005] To achieve the above objectives, the present invention employs the following technical solution: In a first aspect, the present invention provides a manual remote-controlled braking system for automobile crash tests, comprising: A wireless remote control switch assembly, comprising a remote controller and an actuator, wherein the remote controller is used to issue control commands and the actuator is used to receive control commands issued by the remote controller; A power connection module is used to connect the power supply terminal of the actuator to the vehicle power supply. The handbrake motor control module includes a wiring harness to two-way connector; the output end of the actuator is connected to the electronic handbrake connectors at both ends of the vehicle through the wiring harness to two-way connector. After receiving the command from the remote control, the actuator controls the electronic handbrake motors at both ends of the vehicle to rotate in both directions to realize the braking operation and thus control the vehicle to decelerate and stop.

[0006] Furthermore, the wireless remote control switch assembly is a dual-channel wireless remote control switch, which can independently control the electronic handbrake motors at both ends of the vehicle.

[0007] Furthermore, the actuator is provided with a magnetic suction unit and a strap, which are used to quickly fix the actuator onto the vehicle.

[0008] Furthermore, it also includes an emergency power module and an audible and visual alarm module, which are electrically connected to the actuator. The emergency power module is configured to automatically provide emergency power to the actuator when the vehicle power supply is interrupted, so that the actuator can drive the electronic handbrake motor to perform at least one emergency braking operation. The audible and visual alarm module is configured to provide an audible and visual alarm when the vehicle power supply is interrupted or the emergency power module has insufficient power.

[0009] Furthermore, the actuator is equipped with an inertial measurement unit, which is used to detect the lateral acceleration of the vehicle.

[0010] Furthermore, the actuator is equipped with a data logger and a USB interface. The data logger is used to record the time and duration of each remote control command, and the data recorded by the data logger is exported through the USB interface.

[0011] Furthermore, the remote control and the actuator are both model TAD-T80.

[0012] Secondly, the present invention provides a method for using a manual remote control braking system in a car crash test, comprising the following steps: Connect the power supply terminal of the actuator to the vehicle power supply; Disconnect the original electronic parking brake connector of the vehicle, and use a wiring harness one-to-two connector to connect the output end of the actuator to the electronic parking brake connectors at both ends of the vehicle respectively. The actuator is fixed to the vehicle; The remote controller sends a control command, and after receiving the signal, the actuator controls the electronic handbrake motors at both ends of the vehicle to rotate in both directions, thereby controlling the braking operation to decelerate and stop the vehicle.

[0013] Furthermore, the actuator is equipped with an inertial measurement unit, including the following steps: The lateral acceleration of the vehicle is acquired in real time by the inertial measurement unit. If the lateral acceleration of the vehicle exceeds the threshold, the actuator controls the electronic handbrake motors at both ends of the vehicle to rotate in both directions to achieve the tightening and loosening of the brakes, thereby controlling the vehicle to decelerate and stop.

[0014] Furthermore, the manual remote braking system in the vehicle crash test is equipped with an emergency power supply module and an audible and visual alarm module, and also includes the following steps: After the actuator's power supply is connected to the vehicle's power supply, the actuator automatically detects the power level of the emergency power module. If the vehicle's power is interrupted, the actuator will issue an audible and visual alarm via the audible and visual alarm module and automatically switch to the emergency power module for power supply. If the power level of the emergency power module is lower than the set power threshold, the actuator will issue an audible and visual alarm via the audible and visual alarm module.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention replaces traditional pneumatic transmission pipelines with wireless signals, eliminating the need for a pneumatic generator and complex oil circuit design, significantly reducing hardware costs and equipment size. The power connection module connects the actuator's power supply to the vehicle's power source, directly utilizing the vehicle's battery power, eliminating the need for an external power source, reducing equipment weight and installation complexity, and simplifying the system structure. The handbrake motor control module includes a wiring harness one-to-two connector; the actuator's output is connected to the electronic handbrake connectors at both ends of the vehicle via this connector, without damaging the vehicle's original brake wiring, preserving the original handbrake function, and reducing modification costs and vehicle wear risks. By integrating wireless remote control technology with the vehicle's existing electronic handbrake system, this invention avoids the complex design of sensor-dependent automatic braking, effectively reducing equipment size and installation complexity, and solving the problem of existing vehicle braking devices lacking effective remote braking methods in low-speed or no-deviation-risk tests.

[0016] In this invention, the power supply of the actuator is connected to the vehicle's power supply, directly utilizing the vehicle's existing power source, thus reducing hardware costs and complexity. The original vehicle's electronic parking brake connector is disconnected, and a wiring harness one-to-two connector is used to connect the actuator's output to the electronic parking brake connectors at both ends of the vehicle. This preserves the original electronic parking brake function, allowing system expansion solely through quick plug-and-play connector insertion, avoiding damage to the vehicle's original braking wiring. The actuator is fixed to the vehicle to prevent displacement during vehicle vibration or emergency braking, ensuring signal reception and motor control stability. Control commands are issued via the remote control. Upon receiving the signal, the actuator controls the forward and reverse rotation of the electronic parking brake motors at both ends of the vehicle, achieving brake engagement and disengagement, thereby controlling the vehicle to decelerate and stop. Test personnel can operate the remote control from a safe distance, avoiding personal injury due to vehicle loss of control. This invention combines a wireless remote control switch assembly with the vehicle's existing electronic parking brake system and utilizes a wiring harness one-to-two connector in the control circuit, thus avoiding the dependence of traditional vehicle braking equipment on pneumatic power sources and complex piping, significantly reducing equipment costs and size. Meanwhile, the ability to manually trigger braking via remote control solves the problem of lacking an effective remote braking method in low-speed or no-deviation-risk tests, thus simplifying the test preparation process and improving operational safety.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0019] It should be noted that the terms "first," "second," etc., in the specification and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings: See Figure 1 This invention discloses a manual remote-controlled braking system for automobile crash tests, characterized in that it comprises: A wireless remote control switch assembly, comprising a remote controller and an actuator, wherein the remote controller is used to issue control commands and the actuator is used to receive control commands issued by the remote controller; The wireless remote control switch assembly is a signal transmission device based on wireless communication technology. Its main function is to send and receive control commands. Specifically, this assembly can transmit commands via wireless communication methods such as radio frequency signals, Bluetooth, or infrared. For example, a 2.4GHz radio frequency module can be used to achieve signal interaction between the remote control and the actuator, or a short-range wireless connection can be established using the Bluetooth protocol. Its primary purpose is to enable operators to remotely control the vehicle's braking system from a safe distance. By replacing traditional pneumatic transmission pipelines with wireless signals, the need for pneumatic generating devices (air compressors, air tanks) and complex hydraulic circuit designs is eliminated, significantly reducing hardware costs and equipment size. Test personnel can operate the remote control from a safe distance (such as in a control room), avoiding the risk of personal injury due to vehicle malfunction (such as veering or abnormal acceleration).

[0021] A power connection module is used to connect the power terminal of the actuator to the vehicle power supply to obtain power supply. The power connection module provides stable power to the actuator, which can be achieved in various ways. For example, it can be connected to the positive and negative terminals of the vehicle battery via clamp-on electrodes, avoiding the need for an additional independent power supply, eliminating the need for an external power source, reducing equipment weight and installation complexity, and thus simplifying the system structure.

[0022] The handbrake motor control module includes a wiring harness to two-way connector; the output end of the actuator is connected to the electronic handbrake connectors at both ends of the vehicle through the wiring harness to two-way connector. After receiving the command from the remote control, the actuator controls the electronic handbrake motors at both ends of the vehicle to rotate in both directions to realize the braking operation and thus control the vehicle to decelerate and stop.

[0023] The wiring harness to 2-to-1 connector in the handbrake motor control module is a key component for signal distribution and circuit connection. In practical applications, this connector can be implemented using a multi-core cable and branch terminals, such as a Y-type splitter with insulation protection, or by using an integrated circuit board to perform signal splitting and transmission. Its purpose is to ensure that the actuator can simultaneously control the electronic handbrake motors at both ends of the vehicle. Connecting to the original vehicle's electronic handbrake connector via the wiring harness to 2-to-1 connector avoids damaging the vehicle's original brake wiring, retains the original handbrake function, and reduces modification costs and vehicle wear and tear risks.

[0024] This invention provides a lightweight and low-cost remote braking solution by integrating wireless remote control technology with the vehicle's existing electronic parking brake system. Compared to traditional pneumatic devices, this system eliminates the need for complex hydraulic or pneumatic transmission structures, directly utilizing the vehicle's original electronic parking brake system for braking operation. Furthermore, manual braking is achieved through a wireless remote control switch assembly, avoiding the complex design of sensor-dependent automatic braking. This effectively reduces the device's size and installation complexity, and solves the problem of existing vehicle braking devices lacking an effective remote braking method in low-speed or no-drift-risk tests.

[0025] The working principle of this invention is as follows: The remote controller in the wireless remote control switch assembly issues control commands, and the actuator initiates its workflow upon receiving these commands. The power connection module connects the actuator's power supply to the vehicle's power source, providing power to ensure its normal operation. Furthermore, the handbrake motor control module distributes signals via a wiring harness one-to-two connector, with the actuator's output connected to the electronic handbrake connectors at both ends of the vehicle via this connector. Specifically, when the actuator receives a command from the remote controller, it controls the forward and reverse rotation of the electronic handbrake motors at both ends of the vehicle according to the command, thereby controlling the braking. This allows the vehicle to quickly decelerate and stop in case of abnormal conditions during testing. As a preferred implementation, this system directly utilizes the vehicle's original electronic handbrake system, eliminating the need for additional hydraulic or pneumatic transmission devices, significantly simplifying the system structure and reducing equipment size and cost. For example, in a crash test, if the vehicle veers or experiences other abnormal conditions, the operator can remotely trigger the braking operation via the remote controller, ensuring the safety and effectiveness of the test.

[0026] The present invention further proposes that the wireless remote control switch assembly is a dual-channel wireless remote control switch, which can independently control the electronic handbrake motors at both ends of the vehicle.

[0027] Specifically, a dual-channel wireless remote control switch refers to a wireless control device with two independent signal channels, which can be implemented using dual-band wireless communication technology or dual-channel coding technology. Its purpose is to avoid the limitation of a single-channel switch, which can only operate both ends synchronously, by separating the left and right control paths, thereby achieving independent control of the electronic parking brake motors at both ends of the vehicle.

[0028] In detail, this invention employs a dual-channel wireless remote control switch, providing two independent signal channels that allow for independent control of the electronic parking brake motors at both ends of the vehicle based on remote control commands. When the vehicle veers to one side, the operator can selectively apply braking to that side individually, for example, increasing the left wheel braking to correct a rightward veer. This ensures precise distribution of braking force, improves the controllability of the braking process, and effectively reduces the risk of accidental collisions caused by veerging. Simultaneously, the use of the wireless remote control switch assembly, actuators, and other basic components further enhances the system's practicality and safety, resolving the issue of inaccurate braking when the vehicle veers during collision tests.

[0029] The present invention further proposes that the actuator be equipped with a magnetic suction unit and a strap, the magnetic suction unit and the strap being used to quickly and securely mount the actuator onto a vehicle, thereby ensuring stable reception of commands issued by the remote control during vehicle operation.

[0030] Specifically, a magnetic unit is a device that uses magnetic attraction to achieve rapid fixation, which can be implemented using permanent magnets or electromagnets. A strap is a flexible restraint device, which can be made of Velcro, clips, or elastic materials, depending on the vehicle's surface material and structural characteristics. The magnetic unit is designed to provide immediate fixation, significantly improving installation efficiency during test preparation, while using magnetic force to resist vibration and impact, maintaining actuator position stability. Straps, as a supplementary fixation method, are designed to adapt to different vehicle structures, providing additional restraint to prevent actuator displacement during strong vibrations or accidental collisions.

[0031] In detail, the magnetic unit is designed based on the common characteristics of vehicle metal components, enabling it to quickly adhere to the vehicle surface and achieve immediate fixation without tools. During vehicle operation, the magnetic unit uses magnetic force to resist vibration and impact, maintaining the actuator's stable position and preventing signal interruption due to bumps. The straps can be flexibly wrapped around non-metallic components or frames according to the diversity of vehicle structures, providing additional restraint, especially suitable for scenarios where magnetic attraction is insufficient. This combination not only adapts to the installation requirements of different vehicle surfaces but also forms a dual fixing mechanism, ensuring the actuator's continuous and stable operation under harsh conditions such as crash tests. This fundamentally eliminates signal reception failures caused by insecure installation, enabling reliable transmission of remote control commands and execution of braking operations.

[0032] This invention further proposes an emergency power supply module and an audible and visual alarm module. The emergency power supply module is electrically connected to the actuator and is configured to automatically provide emergency power to the actuator when the vehicle's power supply is interrupted, enabling the actuator to drive the electronic handbrake motor to perform at least one emergency braking operation. The audible and visual alarm module is configured to issue an audible and visual alarm when the vehicle's power supply is interrupted or the emergency power supply module's power is insufficient, facilitating timely monitoring of the power supply status and preventing the system from malfunctioning due to insufficient power during experiments.

[0033] An emergency power module is a backup power supply device independent of the vehicle's main power supply. It can be implemented using energy storage components such as lithium battery packs, supercapacitors, or lead-acid batteries. In practical applications, the emergency power module monitors the vehicle's power status in real time through a built-in power management chip and quickly switches to backup power mode when a voltage drop or open circuit is detected. Its purpose is to ensure that actuators can maintain critical functions even in the event of a vehicle power failure, preventing braking system paralysis due to power interruption. In extreme cases of vehicle power supply interruption, the system can still reliably perform emergency braking operations, significantly improving safety during vehicle crash tests.

[0034] When vehicle power is interrupted, the emergency power module can respond immediately and provide power support, completing the power switch without any manual intervention. Specifically, the emergency power module is designed to support at least one emergency braking operation, considering both basic test safety requirements and avoiding the bulk and cost burden of excessive redundancy. Furthermore, the combined use of the emergency power module and actuators not only solves the problem of braking failure in vehicle power interruption scenarios but also ensures that the system restores braking capability within milliseconds, effectively preventing secondary accidents caused by vehicle loss of control.

[0035] The present invention further proposes an inertial measurement unit, which is arranged on an actuator and is used to detect the lateral acceleration of a vehicle.

[0036] Specifically, an inertial measurement unit (IMU) is a sensor device capable of sensing changes in the motion state of an object. It can be implemented using a MEMS accelerometer, gyroscope, or a combination of both. In practical applications, the IMU is typically integrated within the actuator and communicates with the main control circuit via an I2C or SPI interface. The purpose of introducing an IMU is to monitor the lateral dynamic characteristics of the vehicle in real time, providing the system with accurate vehicle status information.

[0037] When lateral acceleration exceeds a preset threshold, the actuator automatically triggers braking control commands. This effectively compensates for the shortcomings of relying solely on manual operation, especially in emergency situations such as abnormal vehicle deviation. The system can react quickly without waiting for operator judgment and action. Simultaneously, integrating the inertial measurement unit directly into the actuator avoids the complexity of additional wiring and independent sensor installation, ensuring reliable and real-time signal transmission. Lateral acceleration, as a crucial indicator of vehicle lateral stability, accurately characterizes potential trajectory deviation risks during testing. Compared to traditional longitudinal deceleration detection methods, it more promptly reflects the vehicle's lateral loss-of-control tendency, thus significantly improving the system's safety response capabilities.

[0038] The present invention further proposes to set a data logger and a USB interface on the actuator, wherein the data logger is used to record the time and duration of each remote control command, and the data recorded by the data logger is exported through the USB interface.

[0039] A data logger is an electronic module capable of capturing and storing time-related data, typically implemented using flash memory chips and a real-time clock circuit. A USB interface can be understood as a hardware interface conforming to the Universal Serial Bus standard, implemented through the integration of a USB controller chip. The purpose of introducing a data logger is to ensure the traceability of remote control operations, while the USB interface facilitates convenient data transfer.

[0040] In detail, the data logger on the actuator is directly linked to the control circuit. When the remote control issues a command, the data logger synchronously records the trigger time and duration of the command, thus forming a precise operation timeline. This avoids timing deviations that may be caused by external device intervention, ensuring the accuracy of the recorded data. Simultaneously, the use of a USB interface allows test personnel to quickly import recorded data into general analysis equipment, significantly improving data processing efficiency. It facilitates the complete reconstruction of the braking operation sequence, providing a reliable basis for analyzing the timeliness of vehicle deceleration and stopping. Combined with the wireless remote control switch assembly, handbrake motor control module, and other basic structures, it forms a complete remote control braking system, effectively solving the problem of insufficient precise traceability in remote control operations.

[0041] Preferably, the remote controller and the actuator are model TAD-T80.

[0042] See Figure 2 Based on the manual remote braking system used in automobile crash tests, this invention also discloses a method for using the manual remote braking system in automobile crash tests, including the following steps: S1, connect the power supply of the actuator to the vehicle's power supply, directly utilize the vehicle's existing power supply (12V / 24V), eliminate the need for external power equipment such as air compressors and air tanks in traditional pneumatic brake systems, and reduce hardware costs and complexity.

[0043] In this embodiment of the invention, after the actuator's power supply is connected to the vehicle's power supply, the actuator automatically detects the power level of the emergency power module. If a power outage is detected, the actuator activates an audible and visual alarm via the audible and visual alarm module and automatically switches to the emergency power module for power supply. If the emergency power module's power level is detected to be lower than a set power threshold, the actuator also activates an audible and visual alarm via the audible and visual alarm module. This dual power supply switching and real-time power status monitoring helps ensure the reliability of the system operation.

[0044] S2, disconnect the original electronic parking brake connector from the vehicle, and use a wiring harness 1-to-2 connector to connect the output end of the actuator to the electronic parking brake connectors at both ends of the vehicle. This retains the original electronic parking brake function, achieving system expansion only through quick plug-and-play connectors, avoiding damage to the vehicle's original brake wiring, and reducing modification risks and costs.

[0045] S3. Fix the actuator to the vehicle. The actuator is small in size and can be concealed in an empty area inside the vehicle (such as under the dashboard or under the seats) to avoid occupying test space. Fixed installation prevents the actuator from shifting during vehicle vibration or emergency braking, ensuring the stability of signal reception and motor control.

[0046] S4. A control command is issued via the remote control. Upon receiving the signal, the actuator controls the electronic handbrake motors at both ends of the vehicle to rotate in both directions, thereby controlling the braking operation and slowing down the vehicle to a stop. Test personnel can operate the remote control from a safe distance (such as in the control room or protected area) to avoid personal injury caused by vehicle loss of control (such as veering or abnormal acceleration).

[0047] This invention combines a wireless remote control switch assembly with the vehicle's existing electronic parking brake system and utilizes a wiring harness one-to-two connector to intervene in the control circuit. This avoids the dependence of traditional vehicle braking equipment on pneumatic power sources and complex pipelines, significantly reducing equipment cost and size. Simultaneously, it enables manual braking via remote control, solving the problem of lacking an effective remote braking method in low-speed or no-deviation-risk tests, thus simplifying test preparation procedures and improving operational safety.

[0048] In a preferred embodiment, the present invention further includes the following steps: The lateral acceleration of the vehicle is acquired in real time by the inertial measurement unit. If the lateral acceleration of the vehicle exceeds the threshold, the actuator controls the electronic handbrake motors at both ends of the vehicle to rotate in both directions to achieve the tightening and loosening of the brakes, thereby controlling the vehicle to decelerate and stop.

[0049] In a preferred embodiment of the present invention, when installing the actuator, the original electronic parking brake connector of the vehicle is first disconnected, and then the output end of the actuator is connected to the electronic parking brake connectors at both ends of the vehicle through the wiring harness one-to-two connector.

[0050] This invention enables vehicles that exhibit deviation or abnormal behavior during actual crash tests, even those without onboard braking systems, to achieve braking control using the method described herein. In practical applications, before installing the actuator, the vehicle's original electronic parking brake connector is disconnected to ensure no direct electrical connection between the original electronic parking brake system and external devices. This is to avoid short-circuit risks caused by signal superposition or abnormal current loops, thus ensuring circuit safety. This operation can be performed manually by unplugging the connector or with the assistance of a special tool. The wiring harness one-to-two connector can be a cable assembly with an adapter interface, used to achieve independent connection between the actuator output and the left and right motor connectors. This aims to maintain the forward and reverse rotation control function of the electronic parking brake motor and eliminate potential interference.

[0051] The above content is only for illustrating the technical concept of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made to the technical solution based on the technical concept proposed in this invention shall fall within the scope of protection of this invention.
