Abstract
Description
Technical Field
[0001] This application relates to an automatic turn signal deactivation system, and more particularly to an automatic turn signal deactivation system and its implementation method that can automatically deactivate a powered vehicle after the turn signal is activated. Background Technology
[0002] As is well known, turn signals are essential warning lights for turning or changing lanes. Cars and motorcycles display turn signals before starting, when changing lanes, and when turning, so that oncoming or following vehicles can know their direction of travel, thereby improving traffic flow and the safety of all drivers.
[0003] However, for two-wheeled vehicles, the existing turn signals are manually controlled. The turn signal is used to warn of the direction of the turn before turning, and the turn signal is manually turned off after turning. However, when turning continuously, changing lanes, or after a sharp turn, the driver usually cannot immediately manually control the turn signal switch, which causes confusion for the driver. If the driver needs to control the vehicle direction and turn on / off the warning lights at the same time, it will distract or panic the driver, thus affecting the safety of other road users. In addition, there are cases where drivers forget to turn off the turn signal after turning. In addition to wasting power, it is also easy for vehicles in front and behind to not be able to accurately predict the direction of travel, resulting in collisions.
[0004] Furthermore, the turn signal switch for two-wheeled vehicles is located on the left handlebar. When the driver turns on the turn signal, they usually switch the switch with their left thumb. At this time, only four fingers of the left hand are left to hold the handlebar. If an emergency occurs at this time, it may delay the driver's balance and reaction ability to control the motorcycle, thereby endangering the life safety of the driver or other road users.
[0005] Therefore, the prior art provides a turn signal reset device, which connects a turn signal to a control unit, and the control unit is coupled to a gravity inertial sensing unit. After the driver displays the turn signal and turns, the vehicle body will form a tilt angle when turning. After the gravity inertial sensing unit senses the tilt of the vehicle body, it sends a signal to the control unit, which then resets the turn signal. However, using the gravity inertial sensing unit to sense the tilt angle of the vehicle body is prone to misjudgment. For example, when stopping at a traffic light and wanting to turn, one must first stop and display the turn signal to warn oncoming vehicles so that one can turn when the light turns green. When the driver stops, the vehicle body often tilts so that the driver's feet can easily touch the ground to maintain the vehicle's balance, especially common among smaller people. Therefore, if the gravity inertial sensing unit misjudges the vehicle body tilt when it stops and turns off the turn signal, preventing the turn signal from being continuously displayed, it will affect the driver and oncoming vehicles, affecting traffic flow and the traffic safety of all road users. Summary of the Invention

The condition judgment module has a default angle threshold, and selects whether to generate a shutdown signal based on the result of comparing the vehicle body angle information with the angle threshold; and if the condition judgment module generates the shutdown signal, the processing module shuts down the light source module according to the shutdown signal.
[0007] In one embodiment, the automatic turn signal off system further includes a countdown module coupled to the light source module, which receives the light source signal and executes a countdown. When the status determination module does not generate the off signal, the light source module turns off after the countdown is completed.
[0008] In one embodiment, the automatic turn signal deactivation system further includes a distance sensing module coupled to the light source module. The distance sensing module has a default distance threshold. When the distance sensing module receives the light source signal, it starts to calculate a displacement distance of the powered vehicle. If the displacement distance is greater than the distance threshold and the condition judgment module generates the shutdown signal, the processing module shuts down the light source module according to the shutdown signal.
[0009] In one embodiment, the angle threshold includes a tilt angle threshold and a line angle threshold.
[0010] In one embodiment, the tilt threshold is an angle increase or decrease of more than 20 degrees, and the line angle threshold is an angle increase or decrease of more than 10 degrees.
[0011] This application also provides a method for implementing an automatic turn signal deactivation system, used to automatically shut off a light source module on a powered vehicle, comprising:
[0012] The execution steps of a light source are as follows: A processing module drives the light source module to generate a light source signal;
[0013] A vehicle body angle measurement step: After measuring the current tilt angle of the powered vehicle using an inertial measurement module, a vehicle body angle information is generated;
[0014] A condition judgment step: The condition judgment module has a default angle threshold. The module selects whether to generate a shutdown signal based on the result of comparing the vehicle body angle information with the angle threshold.
[0015] Step 1: If the condition judgment module generates the shutdown signal, the processing module shuts down the light source module according to the shutdown signal.
[0016] In one embodiment, after the status judgment step is performed, a countdown step is executed. The countdown step includes a countdown module coupled to the light source module. After receiving the light source signal, the countdown module executes a countdown. When the status judgment module does not generate the shutdown signal, the light source module shuts down after the countdown is completed.
[0017] In one embodiment, after the condition judgment step is performed, a distance sensing step is executed. The distance sensing step includes a distance sensing module coupled to the light source module, and the distance sensing module has a default distance threshold. When the distance sensing module receives the light source signal, the distance sensing module starts to calculate a displacement distance of the powered vehicle. If the displacement distance is greater than the distance threshold, and the condition judgment module generates the shutdown signal, the light source module is turned off.

[0032] As Figure 1 shown Figure 1 is a block diagram schematic of an automatic cancellation system for direction lights according to an embodiment of the present application. As shown in the figure, an automatic cancellation system 10 for direction lights is mainly disposed in a powered vehicle 11, and the powered vehicle 11 may be, for example, a locomotive or other transportation means.
[0033] Specifically, the automatic cancellation system 10 for direction lights mainly includes a processing module 101, a light source module 102, an inertial measurement module 103, and a condition judgment module 104. Among them, the processing module 101 is coupled to the light source module 102, the inertial measurement module 103, and the condition judgment module 104, and is used to drive each module to act. The processing module 101 may be, for example, a central processing unit, a microprocessor, etc.
[0034] The light source module 102 is disposed on the powered vehicle 11. The light source module 102 is mainly the direction light on the powered vehicle 11, but the type of the light source module 102 is not limited, and the light source module 102 can be driven by the processing module 101 to generate a light source, and a light source signal M1 is generated after being driven.
[0035] The inertial measurement module 103 may be, for example, an Inertial Measurement Unit (IMU), mainly composed of multiple sensors, used to measure and report the acceleration, angular velocity, and direction of an object, used to measure the body tilt angle of the powered vehicle 11, and a body angle information M2 is generated after measurement.
[0036] The condition judgment module 104 is coupled to the inertial measurement module 103 to receive the vehicle body angle information M2. The condition judgment module 104 has a default angle threshold M3, which is a limit value that restricts the tilt of the powered vehicle 11 to a certain degree. For example, the tilt angle of the vehicle body cannot increase or decrease by more than 10 degrees. The condition judgment module 104 determines whether the tilt angle of the powered vehicle 11 exceeds the angle threshold M3 based on the result of comparing the vehicle body angle information M2 with the angle threshold M3, and selects whether to generate a shutdown signal M4.
[0037] Please see Figure 2 , Figure 2 This is a block diagram of an automatic turn signal deactivation system according to another embodiment of this application. In this embodiment, based on the above embodiment, the angle threshold M3 includes a tilt angle threshold M31 and a line angle threshold M32, and the tilt angle of the tilt angle threshold M31 and the line angle threshold M32 is as follows: Figure 3 As shown in the figure, the tilt angle is a schematic diagram of the tilt angle of the tilt angle threshold and the line angle threshold.
[0038] In one embodiment, the tilt angle threshold M31 is defined as an angle increase or decrease exceeding 20 degrees, and the tilt angle threshold M32 is defined as an angle increase or decrease exceeding 10 degrees. Taking the tilt angle threshold M31 as an example, when the vehicle body of the powered vehicle 11 is parked, the inertial measurement module 103 will detect the tilt angle of the vehicle body when it is parked. Assuming the tilt angle between the vehicle body and the ground is 30 degrees, if the tilt angle of the vehicle body is affected by external forces or other factors and exceeds 50 degrees or 10 degrees, that is, exceeding the angle range limit, the system will perform subsequent operations exceeding the angle range limit. Furthermore, if the situation judgment module 104 generates the shutdown signal M4, the shutdown signal M4 will be transmitted to the processing module 101, and the processing module 101 will shut down the light source module 102 according to the shutdown signal M4.
[0039] Please see Figure 4 The diagram below illustrates the composition of the countdown module in this application. In one embodiment, the automatic turn signal deactivation system 10 further includes a countdown module 106. The countdown module 106 is coupled to the light source module 102 and is used to receive the light source signal M1 and execute a countdown. When the status judgment module 104 does not generate the off signal M4, the light source module 102 is turned off after the countdown is completed.
[0040] Please see Figure 5The diagram below illustrates the composition of the distance sensing module in this application. In one embodiment, the automatic turn signal deactivation system 10 further includes a distance sensing module 106, which is coupled to the light source module 102. The distance sensing module 106 has a default distance threshold M5, which is a range value that limits the movement distance, such as 10 meters. When the distance sensing module 106 receives the light source signal M1, it starts to calculate a displacement distance of the powered vehicle 11. This displacement distance is the distance that the distance sensing module 106 begins to move immediately after receiving the light source signal M1. If the displacement distance is greater than the distance threshold M5, and the situation judgment module 104 generates the shutdown signal M4, then the processing module 101 shuts down the light source module 102 according to the shutdown signal M4.
[0041] Please see Figure 6 This is a schematic diagram illustrating the implementation steps of this application; please refer to it in conjunction with other relevant documents. Figures 1-5 The implementation method of this system is as follows:
[0042] Step S1: Light source execution steps.
[0043] Specifically, the processing module 101 drives the light source module 102 to generate the light source signal M1.
[0044] Step S2: Vehicle body angle measurement steps.
[0045] Specifically, the inertial measurement module 103 measures the current tilt angle of the powered vehicle 11 and generates the vehicle angle information M2. The purpose of detecting the tilt angle is to determine whether the powered vehicle 11 is currently turning.
[0046] Step S3: Situation assessment step.
[0047] Specifically, the condition judgment module has a default angle threshold M3. The condition judgment module 104 selects whether to generate the shutdown signal M4 based on the result of comparing the vehicle body angle information M2 with the angle threshold M3. The angle threshold M3 is a limit value that restricts the tilt of the powered vehicle 11 to a certain degree. Please refer to the relevant documentation. Figure 7 This is a schematic diagram of the tilt angle of a powered vehicle. For example, the tilt angle θ of the vehicle body must not increase or decrease by more than 10 degrees. If the powered vehicle 11 is in a 90-degree upright riding condition, and the left and right tilt angles of the powered vehicle 11 exceed 100 degrees and 80 degrees, it means that the powered vehicle 11 is in a cornering state, and the system should not turn off the light source module 102.
[0048] Step S4: Turn off the light source.
[0049] Specifically, if the situation judgment module 104 generates the shut-off signal M4, it means that the vehicle angle information M2 has not exceeded the range of the angle threshold M3. At this time, the situation should be that the powered vehicle 11 has completed the cornering. Then the processing module 101 can shut down the light source module according to the shut-off signal M4.
[0050] Please see Figure 8 This is a diagram illustrating the countdown steps of this application; please refer to it in conjunction with the documentation. Figures 1 to 5 In one embodiment, after implementing the situation judgment step S3, a countdown step S5 is executed. The countdown step S5 mainly includes a countdown module 105 coupled to the light source module 102. After receiving the light source signal M1, the countdown module 105 executes a countdown. When the situation judgment module 104 does not generate the shutdown signal M4, the light source module 102 is shut down after the countdown is completed. This step is mainly to avoid the system being unable to shut down the light source module 102 due to its inability to accurately judge the tilt angle of the power vehicle 11. Therefore, the countdown module 105 can be forcibly shut down after a countdown time after the light source module 102 is started. The number of seconds of the countdown can be estimated based on the general cornering time.
[0051] Please see Figure 9 This is a schematic diagram of the distance sensing steps in this application. Please refer to it for further details. Figures 1 to 5 In one embodiment, after performing the situation judgment step S3, a distance sensing step S6 is executed. This distance sensing step S6 includes a distance sensing module 106, which is coupled to the light source module 102. The distance sensing module 106 has a default distance threshold M5. When the distance sensing module 106 receives the light source signal M1, it begins to calculate a displacement distance of the powered vehicle 11. If the displacement distance is greater than the distance threshold M5, and the situation judgment module… When group 104 generates the shutdown signal M4, the processing module 101 shuts down the light source module 102. As mentioned above, the main purpose of implementing the distance sensing step S6 is that if the light source module 102 is shut down immediately after a turn, the return-to-center buffer time of the powered vehicle 11 will be reduced when passing through a larger curve, which may lead to a rear-end collision. Therefore, even if the powered vehicle has completed a turn, if the light source module can be shut down after a certain distance has been traveled, it will definitely increase the safety of the driver.
[0052] In summary, the automatic turn signal deactivation system 10 of this application mainly determines whether the light source module 102 should be turned off by automatically detecting the status of the powered vehicle 11 by each module of the system, which effectively increases the convenience and safety of the driver when riding the powered vehicle 11. Therefore, the automatic turn signal deactivation system 10 of this application can indeed achieve the purpose of automatically turning off the turn signal after it has been turned on.
