Description

Technical Field

[0001] The present invention relates to a windshield auto-cancel system, and particularly refers to a system that can automatically cancel the windshield after it is lit in a motor vehicle.

Background Art

[0002] The windshield is an essential warning light when changing directions or lanes. Motor vehicles and motorcycles must turn on the windshield before starting, when changing lanes and directions, and by notifying oncoming vehicles or following vehicles of the direction of the vehicle in advance, it improves traffic smoothness and driver driving safety.

[0003] However, in the case of motorcycles, the conventional windshield is manually controlled. In order to warn the turning direction in advance before turning a curve, the windshield needs to be turned on, and it is necessary to manually control the extinguishing of the windshield after changing the direction. However, during continuous curves, lane changes, or after sharp curves, usually, the driver cannot immediately manually control the turning on and off of the windshield, which troubles the driver. When it is necessary to control the direction of the vehicle and the turning on and off of the warning light simultaneously, the driver may become distracted or panicked, resulting in affecting the safety of road users. In addition, the driver may forget to turn off the windshield after changing the direction. As a result, not only is power consumed, but the vehicles in front and behind cannot accurately predict the direction of the vehicle, and there is a possibility of a collision accident.

[0004] Furthermore, the switch of the motorcycle windshield is located on the left handle grip. When the driver turns on the windshield, usually, the switch is switched with the thumb of the left hand. At this time, the left hand holds the handle of the motorcycle with the remaining four fingers. In such a situation, when encountering an emergency, the driver may be unable to maintain the balance of the motorcycle or the reaction speed may become slow, and as a result, there is a risk of endangering the life safety of the driver or road users.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Conventionally, a turn signal reset device has been provided in which a control unit is connected to the turn signal, a gravity inertia detection unit is coupled to the control unit, and after the driver turns on the turn signal to change direction, an inclination angle is formed in the vehicle body during the change of direction, the gravity inertia detection unit detects the inclination of the vehicle body, a signal is sent to the control unit, and the control unit resets the turn signal. However, detecting the inclination angle of the vehicle body using the gravity inertia detection unit is prone to misjudgment. For example, when trying to change direction while waiting at a traffic light, the driver will always stop moving first and turn on the turn signal at the same time to indicate the direction of change to surrounding vehicles so that they can change direction as soon as the light turns green. Also, when the driver stops moving, they often tilt the vehicle body to make it easier to put their feet on the ground and maintain balance, and this is especially common among shorter drivers. Therefore, if the gravity inertia detection unit misdetects the tilt of the vehicle when it is stopped, the turn signal may be turned off, preventing it from remaining displayed. This could affect the driver and surrounding vehicles, potentially impacting traffic flow and the safety of road users. [Means for solving the problem]

[0017] As shown in FIG. 1, FIG. 1 is a configuration diagram of the system of the present invention. Like the windshield wiper cancel system 10 shown in the drawing, the windshield wiper cancel system 10 is mainly provided on a motor vehicle 11, and the motor vehicle 11 may be a vehicle such as a motorcycle.

[0018] As described above, the turn signal auto-cancel system 10 mainly includes a processing module 101, a light source module 102, an inertial measurement module 103, and a situation judgment module 104. The processing module 101 is coupled to each module and used to drive and operate each module, and may be, for example, a central processing unit or a microprocessor. The light source module 102 is provided on the powered vehicle 11, and the light source module 102 is mainly a turn signal on the powered vehicle 11, but the type of light source module 102 is not limited, and the light source module 102 generates a light source in response to the drive of the processing module 101 and can generate a light source signal M1 after the drive. The inertial measurement module 103 may be, for example, an IMU (Inertial Measurement Unit), and mainly consists of multiple sensors, and is used to measure and report the acceleration, angular velocity and direction of an object, and is used to measure the body tilt angle of the powered vehicle 11, and generates body angle information M2 after the measurement. The situation determination module 104 is coupled to the inertial measurement module 103 and is used to receive vehicle body angle information M2. An angle threshold M3 is pre-set and is a limiting range value that restricts the vehicle body tilt of the powered vehicle 11 to a certain number of degrees. For example, the vehicle body tilt angle must not increase or decrease by more than 10 degrees. Based on the result of comparing the vehicle body angle information M2 and the angle threshold M3, the situation determination module 104 determines whether the tilt angle of the powered vehicle 11 exceeds the angle threshold M3 and selects whether to generate an off signal M4. Referring to Figure 2, Figure 2 is a schematic diagram of the angle threshold of the present invention. In one embodiment, the angle threshold M3 includes a tilt angle threshold M31 and a column angle threshold M32, and the tilt angles of the tilt angle threshold M31 and the column angle threshold M32 are as shown in Figure 3, which is a schematic diagram of the tilt angles of the tilt angle threshold M31 and the column angle threshold M32. Furthermore, it is preferable that the tilt angle threshold M31 has an angle increase or decrease of more than 20 degrees, and the column angle threshold M32 has an angle increase or decrease of more than 10 degrees. When the status judgment module 104 generates an off signal M4, the off signal M4 is sent to the processing module 101, and the processing module 101 turns off the light source module 102 according to the off signal M4.

[0019] Referring to FIG. 4, FIG. 4 is a configuration diagram of the countdown module of the present invention. In one embodiment, the wiper auto-cancel system 10 further includes a countdown module 105 coupled to the light source module 102 for performing a countdown after receiving the light source signal M1. When the situation determination module 104 does not generate the off signal M4, the light source module 102 turns off after the countdown is completed.

[0020] Referring to FIG. 5, FIG. 5 is a configuration diagram of the distance detection module of the present invention. In one embodiment, the wiper auto-cancel system 10 further includes a distance detection module 106. The distance detection module 106 is coupled to the light source module 102, and a distance threshold M5 is provided in advance. The distance threshold M5 is a range value that limits the moving distance, for example, 10 meters. When the distance detection module 106 receives the light source signal M1, the distance detection module 106 starts to calculate the displacement distance of the motor vehicle 11. When the displacement distance is greater than the distance threshold M5 and the situation determination module 104 generates the off signal M4, the processing module 101 turns off the light source module 102 according to the off signal M4.

[0021] Referring to FIG. 6, FIG. 6 is a schematic diagram of the implementation steps of the present invention. Referring to FIGS. 1 to 5 together, the implementation method of the present system is as follows. Light source execution step S1: The processing module 101 drives the light source module 102 to generate the light source signal M1. Vehicle body angle measurement step S2: After measuring the current vehicle body tilt angle of the motor vehicle 11 by the inertial measurement module 103, the vehicle body angle information M2 is generated. The purpose of detecting the vehicle body tilt angle is to determine whether the motor vehicle 11 is currently in a state of turning a curve. Situation determination step S3: The situation determination module has a pre-set angle threshold M3, and it selects whether to generate an off signal M4 based on the result of comparing the vehicle body angle information M2 with the angle threshold M3. In short, the angle threshold M3 is a limiting range value that restricts the amount of inclination of the vehicle body of the powered vehicle 11 that it must not exceed. Referring to Figure 7, which is a schematic diagram of the inclination angle of the powered vehicle. For example, the increase or decrease in the vehicle body inclination angle θ must not exceed 10 degrees, and when riding in the powered vehicle 11 in an upright position at 90 degrees, if the left and right inclination angles of the powered vehicle 11 exceed 100 degrees and 80 degrees, it indicates that the powered vehicle 11 is turning a curve, and the system should not turn off the light source module 102. Light source off step S4: When the situation determination module 104 generates an off signal M4, it indicates that the vehicle body angle information M2 does not exceed the range of the angle threshold M3. This situation indicates that the powered vehicle 11 has finished turning the curve, and the processing module 101 can turn off the light source module in accordance with the off signal M4.

[0022] Referring to Figure 8, which is a schematic diagram of the countdown step of the present invention, referring to Figures 1 to 5 together, in one embodiment, the countdown step S5 is performed after the situation determination step S3 is performed, and in the countdown step S5, there is a countdown module 105 mainly coupled to the light source module 102, the countdown module 105 performs a countdown after receiving the light source signal M1, and if the situation determination module 104 does not generate an off signal M4, the light source module 102 turns off after the countdown is completed. The main purpose of this step is to avoid a situation where the system cannot accurately determine the tilt angle of the powered vehicle 11 and the light source module 102 cannot be turned off for a long time, for this reason the countdown module 105 can be forcibly turned off after the countdown after the light source module 102 has been activated, and the number of seconds of the countdown can be estimated based on the typical time it takes to turn a curve.

[0023] Referring to Figure 9, which is a schematic diagram of the distance detection step of the present invention, referring to Figures 1 to 5 together, in one embodiment, the distance detection step S6 is performed after the situation determination step S3 is performed. In the distance detection step S6, there is a distance detection module 106 coupled to the light source module 102 and having a distance threshold M5 set in advance. When the distance detection module 106 receives the light source signal M1, it starts calculating the displacement distance of the powered vehicle 11. If the displacement distance is greater than the distance threshold M5 and the situation determination module 104 generates an off signal M4, the processing module 101 turns off the light source module 102. As described above, the main purpose of performing the distance detection step S6 is as follows: If the light source module 102 is turned off immediately after completing a turn, the buffer time for the powered vehicle 11 to return to its original position when turning a large curve is shortened, increasing the risk of being rear-ended by a following vehicle. Therefore, if the light source module can be turned off after traveling a certain distance, even after completing a turn, driver safety can be improved.

[0024] In summary, the turn signal auto-cancel system 10 of the present invention primarily works by having each module of the system automatically detect the status of the powered vehicle 11 to determine whether the light source module 102 should be turned off, thereby effectively improving the convenience and safety of the driver when riding in the powered vehicle 11. Therefore, the turn signal auto-cancel system 10 of the present invention can certainly achieve the objective of automatically turning off the turn signals after they have been turned on.
