[0032] The technical solutions in the embodiments of the application will be apparently and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0033] The above purposes, features and advantages of the application will be more apparent and easy to understand. The application will be further described in detail below with reference to the drawings and specific embodiments.

[0034] The purpose of the application is to make the rear vehicle have enough reaction time to take deceleration or other avoidance measures to avoid rear-end collision, collision and other traffic accidents when the two-wheeled electric vehicle frequently brakes on the road, and to warn pedestrians around the vehicle to avoid, improve the driving safety of the vehicle, and reduce other secondary injuries caused by the rear vehicle driver's insufficient reaction time or the surrounding pedestrians and vehicles not paying attention to the emergency brake vehicle.

[0035] As shown in Figure 1 The embodiments of the application provide an emergency brake warning system, which comprises a motor (driving motor), a brake handle, a turn signal, an integrated flash module (instrument / flasher module) and a controller; the integrated flash module is connected with the controller; and the integrated flash module is connected with the turn signal.

[0036] The controller is used to acquire the reverse acceleration, and determine whether to trigger the emergency brake according to the reverse acceleration, and if yes, generate an emergency brake control instruction; the emergency brake control instruction comprises a double flashing instruction and an increased flashing frequency instruction.

[0037] As an optional implementation, the determination of whether to trigger the emergency brake according to the reverse acceleration specifically comprises:

[0038] determining whether the reverse acceleration reaches a set threshold.

[0039] if yes, triggering the emergency brake.

[0040] if no, not triggering the emergency brake.

[0041] The controller plays a pivotal role in receiving instructions, sending instructions, and executing various operation controls, and is connected to a driving motor, an instrument / flashing module, a brake handle, etc., receives feedback information from each component, reacts, and sends instructions to relevant components to perform operations, such as Figure 2 as shown.

[0042] The integrated flashing module is used to receive the emergency brake control instruction, and control the turn signal to double flash and increase the flashing frequency according to the emergency brake control instruction.

[0043] As an optional implementation, the integrated flashing module comprises a flashing controller and an instrument panel; the flashing controller and the instrument panel are both connected to the controller. The instrument panel is provided with a steering indicator lamp.

[0044] The flashing controller is used to control the turn signal to double flash and increase the flashing frequency according to the emergency brake control instruction.

[0045] The instrument panel is used to make the steering indicator lamp double flash according to the emergency brake control instruction.

[0046] In actual application, the instrument / flashing module comprises an instrument panel interface display, a flashing frequency controller (flashing controller), etc., and is used to receive the execution emergency brake instruction sent by the controller and perform the operations of double flashing of the left and right turn signal indicators of the whole vehicle, increasing the flashing frequency, and restoring the state of the whole vehicle before the emergency brake after the end of the emergency brake; it is connected to the controller and the turn signal; when the controller sends the execution emergency brake instruction, the instrument / flashing module is connected to the left and right turn signal indicators before and after the whole vehicle to double flash, the left and right turn signal indicators of the instrument panel are simultaneously turned on to double flash, and the flashing frequency is simultaneously increased to make the turn signal of the whole vehicle in a stroboscopic state, such as Figure 3 as shown.

[0047] The motor is connected to the controller.

[0048] The controller is also configured to acquire a real-time running state parameter of the motor, and determine whether to trigger the emergency brake according to the real-time running state parameter.

[0049] In actual application, the real-time running state of the driving motor is used as a judgment condition to determine the emergency brake and the normal brake, and is connected to the controller to feed back the real-time running state parameter of the motor to the controller to determine whether it is an emergency brake, as shown in Figure 4 .

[0050] In another embodiment, a pressure sensor can also be used to measure the pressure of the pinch brake or the piston pressure of the brake at the brake handle to determine the emergency brake and the normal brake.

[0051] The turn signal lamp, as the final embodiment of the emergency brake system, is used to flash the warning when the emergency brake is triggered, and is connected to the instrument / flasher module to perform the warning function, as shown in Figure 5 .

[0052] The turn signal lamp continues for a set time after the last time it receives the emergency brake control instruction, and returns to the light state before the emergency brake.

[0053] As an optional embodiment, it also includes a brake handle; the brake handle is connected to the controller; the brake handle is used to generate an emergency brake signal.

[0054] In actual application, the brake handle, as the executor of the brake action, is used to perform the brake operation, including mechanical brake and electronic brake; it is connected to the controller and the motor; the mechanical brake drives the motor and feeds back the electronic brake signal to inform the controller that the whole vehicle stops driving the motor and performs the counter braking, as shown in Figure 6 .

[0055] As shown in Figure 7 , the operation principle of the emergency brake warning system of the present application is as follows:

[0056] When the vehicle is running, the brake is controlled by pinching the brake. When the brake is pinched, the controller receives the electronic brake signal, the controller cuts off the motor output to stop the driving motor and generates counter braking. At this time, the vehicle is still running by relying on its own inertia while the brake is also mechanically braking the motor to reduce the motor speed to achieve the purpose of stopping the vehicle. During the braking process, the whole vehicle speed has a deceleration action from maximum to 0. At this time, the motor acceleration will have a reverse increase, and then recover to 0. When the emergency brake (maximum force pinch brake or normal running sudden emergency brake) is triggered, the vehicle speed will decrease from maximum to 0 in a very short time until the vehicle is stopped. By comparing the acceleration values before and after the emergency brake and the non-emergency brake through repeated tests, a reverse acceleration threshold value can be set to determine the emergency brake and the normal brake action, and the emergency brake warning system is triggered when the set threshold value is reached, as shown inFigure 8 and Figure 9 shown, where the blue line represents the warning signal, the orange line represents the acceleration, the green line represents the brake signal, and the red line represents the threshold line.

[0057] When the controller detects that the reverse acceleration reaches the threshold value, the emergency brake warning system is activated. The controller sends an emergency brake flag (5S, with a set duration) to the instrument panel (with an integrated flashing module) through a communication protocol. The instrument panel receives the emergency brake signal (emergency brake control command) and increases the flashing frequency (for example, from 70 times / min to 100 times / min). At the same time, the left and right turn signal indicators on the instrument panel are turned on with double flashing (which can also be set to emit a warning sound simultaneously). The left and right turn signals on the front and rear of the vehicle are activated with high-frequency double flashing to achieve the warning purpose. The high-frequency double flashing of the left and right turn signals on the front and rear of the vehicle will continue for 5S after the last time the emergency brake signal is received, and then return to the state of the whole vehicle lights before the emergency brake.

[0058] The present application is a safety system that is automatically activated when a two-wheeled vehicle experiences an emergency brake while driving. The system uses a stroboscopic double flashing light to warn vehicles behind that the vehicle in front is experiencing an emergency brake, prompting the vehicle behind to slow down or take other evasive actions to control the vehicle distance and reduce or avoid rear-end accidents. At the same time, the system warns pedestrians in the vehicle's surroundings to avoid the vehicle. This system not only helps to improve the safety of the vehicle itself, but also reduces secondary injuries caused by the driver of the vehicle behind not paying attention to the emergency brake vehicle or other pedestrians and vehicles in the surrounding area. The emergency brake warning system enables the intelligentization of two-wheeled electric vehicles, and the whole vehicle equipped with the emergency brake warning system is more intelligent and safer.

[0059] In addition, the present application realizes functional transformation through a software program scheme, maximally reduces part specification changes, and has cost advantages. No mold changes are involved, which can be applied to the whole vehicle development cycle, and the function can be quickly realized.

[0060] The technical features of the above embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered as within the scope of the present application.

The above examples are only used to help understand the method and core idea of the present application; for those skilled in the art, the specific implementation modes and application scope can be changed according to the idea of the present application.
