Abstract
Description
Technical Field
[0001] The present application relates to the field of automobile safety protection technology, and in particular to an automatic braking device and method for accidental accelerator activation. Background Art
[0002] Currently, when the driver accidentally steps on the accelerator, causing the vehicle to accelerate unexpectedly, traditional vehicles usually lack an active braking mechanism to directly address the accidental accelerator pedaling. Moreover, in vehicles not equipped with intelligent systems, the accelerator and brakes are completely under the independent control of the driver. Even if there are instrument warnings, it all depends on the driver's temporary reaction. In vehicles equipped with intelligent systems, the accidental accelerator suppression system mostly relies on obstacle detection by the vehicle body sensors. If the accelerator is accidentally stepped on on an open road, braking is still not possible, and the deceleration effect is very limited. Summary of the Invention

BRIEF DESCRIPTION OF THE DRAWINGS
[0027] Figure 1 A structural diagram of an autonomous braking device for accidental throttle activation is provided as an exemplary embodiment of the present application.
[0028] Figure 2 A flowchart of an autonomous braking method for accidental throttle activation is provided as an exemplary embodiment of the present application. DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.
[0030] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.
[0031] See Figure 1 , an embodiment of the present application provides an autonomous braking device for accidental throttle activation, the device comprising:
[0032] Induction switch module, brake control module, first push rod, throttle control module and second push rod.
[0033] The sensing switch module, brake control module, first push rod, throttle control module and second push rod in the present application are all small enough in size. Even when the engine compartment layout of fuel vehicles and hybrid vehicles is already very compact, the layout of the engine compartment can still be changed to a minimum extent, so that fuel vehicles, hybrid vehicles and electric vehicles can all be installed with this device; moreover, the cost of each module is low, and there is no need to purchase an expensive control system. The operation of the first push rod and the second push rod can be controlled by using the throttle control module and the brake control module. The installation cost is low and the difficulty is low, and it is easy to be accepted by the public.
[0034] The first push rod is connected to the brake pedal through a steel wire rope; the second push rod is connected to the accelerator pedal through a push rod.
[0035] The first push rod and the second push rod are both electric push rods with a rated voltage of 12 volts.
[0036] The first push rod is connected to the brake pedal via a high-tensile-strength steel cable, employing a flexible transmission method to accommodate pedal travel variations across different vehicle models while avoiding the risk of mechanical jamming associated with a rigid connection. The second push rod, acting directly on the back of the accelerator pedal via a rigid push rod, provides instantaneous reverse thrust when triggered, ensuring the accelerator pedal quickly returns to its initial position and physically disconnecting power output. These dual push rods independently control the brake and throttle, eliminating the response delay caused by mechanical interference in traditional single-actuator solutions. Furthermore, the synchronization error between the brake operation and the throttle disconnection can be controlled to within one second.
[0037] The rated voltage of the electric push rod is directly matched with the on-board 12-volt battery module, eliminating the need for an additional voltage conversion module, reducing the complexity and failure rate of the system. Compared with active braking solutions using high-voltage motors or hydraulic drives, the 12-volt electric push rod of this application achieves triple optimization of energy consumption, cost and safety while ensuring braking response speed through a streamlined mechatronic architecture.
[0038] The sensor switch module is located just below the back of the accelerator pedal; the sensor switch module is used to receive a false touch signal, send a brake start signal to the brake control module, and send a throttle cut-off signal to the throttle control module.
[0039] Among them, the sensing switch module may include a brake sensing switch and a throttle sensing switch arranged side by side; the brake sensing switch is used to receive a false touch signal and send a brake start signal to the brake control module; the throttle sensing switch is used to receive a false touch signal and send a throttle cut-off signal to the throttle control module.
[0040] This application fixes the sensor switch module directly below the back of the accelerator pedal. Using the principle of mechanical leverage, it senses the acceleration of the pedal's displacement in real time. Compared to traditional bottom-mounted pressure sensors, this can identify inadvertent accelerator pedal depressing actions beyond the threshold, such as pedaling speeds exceeding twice the normal acceleration. The brake sensor switch and accelerator sensor switch are placed side by side. When the driver accidentally depresses the pedal, the pedal deflection angle triggers a synchronous signal from both switches, creating a redundant check of the dual signals. This avoids system mis-triggering caused by a single sensor mis-reporting, significantly reducing the misjudgment rate.
[0041] In some embodiments, the inductive switch module may also be a two-in-one two-way two-purpose range switch. The two-in-one two-way two-purpose range switch can further reduce the size of the inductive switch module and make installation more convenient and simple.
[0042] The brake control module is configured to receive a brake activation signal and control the first push rod to rotate forward, thereby controlling the wire rope to pull up the brake pedal and execute the braking operation. The first push rod is also configured to reverse and reset after the braking operation is completed, releasing the wire rope and releasing the brake pedal.
[0043] The first push rod of this application is connected to the brake pedal via a high-tensile-strength steel wire rope. It uses a flexible transmission design to adapt to the pedal travel differences of different vehicle models, ensuring linear transmission of braking force. When the first push rod rotates forward, it automatically tightens the wire rope to trigger the brake operation. When it rotates backward, the tension is simultaneously released and the brake is reset, avoiding the problems of traditional mechanical linkages such as jamming or return delays. After the braking action is completed, the first push rod automatically reverses and resets, while a built-in mechanical return device provides additional redundant force to ensure that the brake pedal is fully returned to its original position. The brake control module monitors the status of the first push rod in real time and triggers the emergency release mechanism in the event of an abnormality to prevent the brake system from accidentally locking.
[0044] The throttle control module receives the throttle cut signal and controls the second push rod to reverse, which in turn controls the push rod to lift the throttle pedal and execute the throttle cut operation. The second push rod also controls the push rod to rotate forward and reset after the throttle cut operation is completed, controlling the push rod to retract and release the throttle pedal.
[0045] The second push rod in this application acts directly on the back of the accelerator pedal via a rigid push rod. When the push rod reverses, it applies reverse thrust, forcing the accelerator pedal to quickly return to its initial position, achieving physical power cutoff. After the push rod returns to its original position, it automatically locks, preventing secondary activation of the accelerator pedal due to vehicle turbulence or misoperation. Furthermore, the second push rod's transmission mechanism utilizes low-temperature and corrosion-resistant materials, ensuring stable operation in extreme temperatures and humid environments.
[0046] The brake control module and the throttle control module achieve synchronized action through hardware-level signal interlocking, ensuring seamless connection between braking operation and throttle cut-off operation; when a single module fails, the other module and the vehicle's own braking system can still work independently to maintain basic safety functions.
[0047] An autonomous braking device for accidental accelerator pedaling provided in the above embodiment introduces an active braking device to prevent accidental accelerator pedaling. It can directly monitor accidental accelerator pedaling operations through the sensing switch module at the bottom of the accelerator pedal, thereby realizing physical braking intervention without relying on obstacle detection by sensors. In addition, a steel wire rope and a push rod are added to achieve faster braking speed without relying on manual driver response. It also covers more potential dangerous scenarios. Regardless of whether there are obstacles or not, it will be triggered as long as there is an accidental accelerator pedaling, providing more safety protection for accidental accelerator pedaling.
[0048] In some embodiments, a battery module is also included to provide 12 volts to the brake control module and the throttle control module. This application utilizes the vehicle's own battery module to provide 12 volts, eliminating the need for an additional voltage conversion module. This reduces system complexity and failure rate, and is highly compatible with 12 volt electric actuators, resulting in excellent performance.
[0049] See Figure 2 Another embodiment of the present application provides an autonomous braking method for accidental throttle activation, the method comprising:
[0050] Step S1: The sensor switch module receives a false touch signal, sends a brake start signal to the brake control module, and sends a throttle cut-off signal to the throttle control module;
[0051] Step S2: The brake control module receives the brake start signal, controls the first push rod to rotate forward, and controls the wire rope to pull up the brake pedal through the first push rod to perform the braking operation;
[0052] In step S3, the throttle control module receives the throttle cut-off signal, controls the second push rod to reverse, and controls the push rod to lift the throttle pedal through the second push rod to perform the throttle cut-off operation.
[0053] In some embodiments, the method further comprises:
[0054] The first push rod is reversed and reset after the brake operation is completed, loosening the wire rope and releasing the brake pedal.
[0055] In some embodiments, the method further comprises:
[0056] The second push rod rotates forward and resets after the throttle switching operation is completed, the control push rod is retracted and the accelerator pedal is released.
[0057] The specific limitations of the method for autonomous braking due to accidental throttle activation provided in this embodiment can be found in the above embodiment of an autonomous braking device due to accidental throttle activation, and will not be repeated here. The various modules in the aforementioned method for autonomous braking due to accidental throttle activation can be implemented in whole or in part through software, hardware, or a combination thereof. The aforementioned modules can be embedded in or independent of a processor in a computer device in hardware form, or can be stored in a memory in a computer device in software form, so that the processor can call and execute the operations corresponding to the aforementioned modules.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
