Description

[Technical Field]

[0001] The present invention relates to a turn signal auto-cancellation system, particularly to a system for a motor vehicle that can automatically cancel a turn signal after it is turned on. [Background technology]

[0002] Turn signals are essential warning lights when changing direction or lanes. Cars and motorcycles must turn on their turn signals before starting off, and when changing lanes or directions. By informing oncoming or following vehicles of the vehicle's direction of travel in advance, they improve traffic flow and driving safety for drivers.

[0003] However, for motorcycles, conventional turn signals are manually controlled, requiring drivers to turn on the turn signal before turning a curve to warn the driver of the direction they are about to turn, and then manually turn off the turn signal after changing direction. However, when navigating successive curves, changing lanes, or after a sharp turn, drivers are usually unable to manually turn on or off the turn signal immediately, causing inconvenience to the driver. Having to simultaneously control the vehicle's direction and the warning lights can lead to distraction and panic, ultimately affecting the safety of road users. Drivers also sometimes forget to turn off the turn signal after changing direction, which not only wastes power but also prevents vehicles in front and behind from accurately predicting the vehicle's direction, potentially resulting in a collision.

[0004] Furthermore, the motorcycle's turn signal switch is located on the left handlebar grip, and when a driver wants to turn on the turn signal, they usually use their left thumb to switch it on, while the remaining four fingers of their left hand grip the handlebars of the motorcycle. In such a situation, if an emergency occurs, the driver may not be able to maintain balance on the motorcycle or their reaction time may be delayed, which may endanger the life and safety of the driver or other road users. Summary of the Invention [Problem to be solved by the invention]

[0005] A conventional turn signal reset device has been provided in which a control unit is connected to a turn signal, and a gravity inertia sensing unit is coupled to the control unit. After a driver turns on the turn signal and changes direction, a tilt angle is formed in the vehicle body during the change of direction. The gravity inertia sensing unit detects the tilt of the vehicle body and then sends a signal to the control unit, which then resets the turn signal. However, using a gravity inertia sensing unit to detect the tilt angle of the vehicle body is prone to erroneous determination. For example, when trying to change direction while waiting at a traffic light, a driver must first stop driving so that they can change direction immediately when the light turns green, and at the same time turn on the turn signal to indicate the direction of change to surrounding vehicles. In addition, when a driver stops driving, they often tilt the vehicle body to make it easier for their feet to touch the ground and maintain balance, which is particularly common among small drivers. Therefore, if the gravitational inertia detection unit detects the inclination of the vehicle body when the vehicle is stopped and makes an erroneous judgment, the turn signal will be turned off and will no longer be displayed continuously, which may have an impact on the driver and surrounding vehicles, and may affect the smooth flow of traffic and the road safety of road users. [Means for solving the problem]

[0006] The present invention provides a turn signal auto-cancellation system and an implementation method thereof for a motor vehicle, the turn signal auto-cancellation system comprising: a processing module for driving each module to operate; a light source module for being mounted on the motor vehicle and generating a light source in response to the driving of the processing module and generating a light source signal after being driven; an inertial measurement module for measuring the vehicle body tilt angle of the motor vehicle and generating vehicle body angle information after the measurement; and a situation judgment module coupled to the inertial measurement module for receiving the vehicle body angle information, the situation judgment module having a preset angle threshold and comparing the vehicle body angle information with the angle threshold to determine whether to generate an OFF signal based on the result of the comparison; a distance detection module coupled to the light source module and having a preset distance threshold; Including, The angle threshold includes the tilt angle threshold and the column angle threshold. , When the distance detection module receives the light source signal, it starts to calculate the displacement distance of the powered vehicle, and if the displacement distance is greater than the distance threshold, andIf the situation determination module generates an off signal, the processing module turns off the light source module according to the off signal.

[0007] In one embodiment, the turn signal auto-cancellation system further includes a countdown module coupled to the light source module for performing a countdown after receiving the light source signal, and if the situation determination module does not generate an off signal, the light source module is turned off after the countdown is completed.

[0008] In one embodiment, the tilt angle threshold is greater than 20 degree increments and the column angle threshold is greater than 10 degree increments.

[0009] The present invention also provides a method for implementing a turn signal auto-cancellation system for automatically turning off a light source module in a motor vehicle, the method for implementing the turn signal auto-cancellation system including a light source execution step in which a processing module drives a light source module to generate a light source signal; a body angle measurement step in which an inertial measurement module measures a current body tilt angle of the motor vehicle and then generates body angle information; a situation judgment module having a preset angle threshold; The angle thresholds include a tilt angle threshold and a column angle threshold; A situation determination step of determining whether to generate an off signal based on a result of comparing the vehicle body angle information with an angle threshold; and a light source off step of turning off the light source module in accordance with the off signal when the situation determination module generates the off signal. After the situation determination step is performed, a distance detection step is performed. In the distance detection step, a distance detection module is coupled to the light source module and has a preset distance threshold. When the distance detection module receives a light source signal, it starts to calculate a displacement distance of the powered vehicle. When the displacement distance is greater than the distance threshold and the situation determination module generates an off signal, it turns off the light source module. .

[0010] In one embodiment, a countdown step is performed after the situation judgment step is performed, and in the countdown step, a countdown module is coupled to the light source module, and when the countdown module performs the countdown after receiving the light source signal, if the situation judgment module does not generate an off signal, the light source module will be turned off after the countdown is completed.

[0017] As shown in Figure 1, Figure 1 is a configuration diagram of the system of the present invention. As shown in the figure, the turn signal auto-cancellation system 10 is mainly installed in a motor vehicle 11, and the motor vehicle 11 may be, for example, a motor vehicle such as a motorcycle.

[0018] As described above, the turn signal auto-cancellation system 10 mainly includes a processing module 101, a light source module 102, an inertial measurement module 103, and a situation assessment module 104. The processing module 101 is coupled to each module and is 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 installed on the motor vehicle 11 and is mainly a turn signal on the motor vehicle 11, but the type of the light source module 102 is not limited. The light source module 102 generates a light source when driven by the processing module 101 and can generate a light source signal M1 after being driven. The inertial measurement module 103 may be, for example, an IMU (Inertial Measurement Unit), mainly composed of multiple sensors, and used to measure and report the acceleration, angular velocity, and direction of an object, and to measure the body tilt angle of the motor vehicle 11 and generate body angle information M2 after measurement. The situation judgment module 104 is coupled to the inertial surveying module 103 and is used to receive the vehicle body angle information M2. The angle threshold M3 is a preset value that limits the vehicle body tilt of the motorized vehicle 11 beyond a certain degree. For example, the vehicle body tilt angle must not increase or decrease by more than 10 degrees. The situation judgment module 104 compares the vehicle body angle information M2 with the angle threshold M3 to determine whether the vehicle body tilt angle exceeds the angle threshold M3 and selects whether to generate an OFF signal M4. Referring to FIG. 2, FIG. 2 is a schematic diagram of the angle thresholds of the present invention. In one embodiment, the angle threshold M3 includes a tilt angle threshold M31 and a row angle threshold M32. The tilt angles of the tilt angle threshold M31 and the row angle threshold M32 are as shown in FIG. 3, which is a schematic diagram of the tilt angles of the tilt angle threshold M31 and the row angle threshold M32. Preferably, the tilt angle threshold M31 has an angle increase / decrease of more than 20 degrees, and the row angle threshold M32 has an angle increase / decrease of more than 10 degrees. When the situation determination 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] 4, which is a block diagram of the countdown module of the present invention. In one embodiment, the turn signal auto-cancellation 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, and if the situation judgment module 104 does not generate an off signal M4, the light source module 102 will be turned off after the countdown is completed.

[0020] 5, which is a block diagram of the distance detection module of the present invention. In one embodiment, the turn signal auto-cancellation system 10 further includes a distance detection module 106, which is coupled to the light source module 102 and has a preset distance threshold M5, which is a range value limiting the travel distance, for example, 10 meters. When the distance detection module 106 receives the light source signal M1, the distance detection module 106 begins to calculate the displacement distance of the motor vehicle 11. If the displacement distance is greater than the distance threshold M5 and the situation judgment module 104 generates an 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 also to Figs. 1 to 5, 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 a light source signal M1. Body angle measurement step S2: After measuring the current body tilt angle of the motor vehicle 11 using the inertial measurement module 103, body angle information M2 is generated. The purpose of detecting the body tilt angle is to determine whether the motor vehicle 11 is currently turning a corner. Situation determination step S3: The situation determination module is provided with a preset angle threshold M3, and determines whether to generate an off signal M4 based on the result of comparing the vehicle body angle information M2 with the angle threshold M3. Simply put, the angle threshold M3 is a limiting range value that limits the degree to which the vehicle body inclination of the motorized vehicle 11 must not exceed. Also refer to FIG. 7, which is a schematic diagram of the motorized vehicle inclination angle. For example, the vehicle body inclination angle θ must not increase or decrease by more than 10 degrees. When riding the motorized vehicle 11 in an upright position of 90 degrees, if the left and right inclination angles of the motorized vehicle 11 exceed 100 degrees and 80 degrees, respectively, this indicates that the motorized vehicle 11 is turning a corner, and the system should not turn off the light source module 102. Light source off step S4: If the situation judgment module 104 generates an off signal M4, it indicates that the vehicle body angle information M2 is not beyond the range of the angle threshold M3, which indicates that the motor vehicle 11 has finished turning the curve, and the processing module 101 can turn off the light source module according to the off signal M4.

[0022] Referring to FIG. 8, FIG. 8 is a schematic diagram of the countdown step of the present invention. Referring also to FIGS. 1 to 5, in one embodiment, the countdown step S5 is performed after the situation determination step S3 is performed. The countdown step S5 mainly includes a countdown module 105 coupled to the light source module 102. The countdown module 105 performs a countdown after receiving the light source signal M1. If the situation determination module 104 does not generate the off signal M4, the light source module 102 turns off after the countdown is completed. The main purpose of this step is to prevent the system from being unable to accurately determine the inclination angle of the motorized vehicle 11 and turning off the light source module 102 for a long time. Therefore, after the light source module 102 is activated, the countdown module 105 can be forced to turn off after the countdown, and the number of seconds for the countdown can be estimated based on the typical time required to turn a corner.

[0023] Referring to FIG. 9, FIG. 9 is a schematic diagram of the distance detection step of the present invention. Referring also to FIGS. 1 to 5, in one embodiment, the distance detection step S6 is performed after the situation determination step S3 is performed. In the distance detection step S6, the distance detection module 106 is coupled to the light source module 102 and has a preset distance threshold M5. When the distance detection module 106 receives the light source signal M1, it begins to calculate the displacement distance of the powered vehicle 11. When 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 the powered vehicle 11 has finished turning a curve, the buffer time required for the powered vehicle 11 to return to its original position when turning a sharp 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 the powered vehicle 11 has traveled a certain distance, even after the powered vehicle has finished turning a curve, driver safety can be improved.

[0024] To sum up, the turn signal auto-cancellation system 10 of the present invention mainly has each module of the system automatically detect the status of the motor 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 motor vehicle 11. Therefore, the turn signal auto-cancellation system 10 of the present invention can indeed achieve the goal of automatically turning off the turn signals after they are turned on.
