Description

TECHNICAL FIELD

[0001] The utility model relates to a steering information sensing device, more specifically, the utility model relates to a steering information sensing device using a pressure sensor to obtain steering information. BACKGROUND

[0002] According to statistics, the proportion of motorcycle accidents in traffic accidents in Taiwan, China is quite high, and the main reason is that the user (i.e. the driver of the motorcycle) lacks experience and skill in handling road conditions. For example: when entering a curve, the speed is too fast, an inappropriate handlebar steering angle (i.e. the inclination angle of the front wheel of the motorcycle relative to the vehicle body) or vehicle body inclination angle (i.e. the inclination angle of the vehicle body relative to the ground) is generated when turning, etc. These inappropriate user behaviors can easily threaten the safety of motorcycle users and other road users. Although users can usually improve their riding and road condition judgment abilities after training. However, the conventional motorcycle training technology is through artificial means to record, analyze and evaluate the handling conditions of the user when riding the curve, but it cannot effectively sense and collect information when riding the curve, and it cannot dataize the information.

[0003] Therefore, how to provide a steering information sensing device that can effectively sense and collect information when the user turns and dataize it is a technical problem that needs to be solved in the technical field to which the utility model belongs. UTILITY MODEL CONTENT

[0004] In order to overcome the above technical problems, the utility model provides a steering information sensing device. The steering information sensing device includes a pressure sensing module, a processor and a memory, and the processor is electrically connected to the pressure sensing module and the memory. The pressure sensing module includes two pressure sensors respectively arranged on a left handlebar part and a right handlebar part on both sides of a handlebar of a vehicle, for sensing a first left pressure value of a left handlebar part and a first right pressure value of a right handlebar part applied by a user when operating the left handlebar part and the right handlebar part to turn. The memory is used to store the first left pressure value and the first right pressure value.

[0005] As mentioned above, the steering information sensing technology provided by the present application senses a pressure value applied to a handlebar of a vehicle by a user when turning (i.e., a first left pressure value corresponding to a left handle portion and a first right pressure value corresponding to a right handle portion) through a pressure sensing module. Then, the steering information sensing technology provided by the present application stores the pressure value. Therefore, the steering information sensing technology provided by the present application can efficiently sense and collect information of the user of the vehicle when turning, and can store the information, thereby providing objective and quantitative information to a person (e.g., the user of the vehicle or a coach of a driving training class) who wants to evaluate the riding condition of the user of the vehicle.

[0006] The above is not intended to limit the present application, but only to generally describe the technical problems that can be solved by the present application, the technical means that can be adopted, and the technical effects that can be achieved, so that the person skilled in the art can initially understand the present application.

Therefore, for example, the first element can be named as the second element without departing from the spirit or scope of the claimed invention.

[0018] Some embodiments of the present invention relate to a steering information sensing device 1, which can be applied to a vehicle (hereinafter referred to as "vehicle") that can be controlled by a user, such as a motorcycle or a bicycle, and in particular to a handlebar (handle) for controlling the riding direction of the vehicle, but not limited thereto. In addition, in this document, the user can ride the vehicle on a closed road (e.g., a driving school road or a race track road) for more accurate information sensing, but not limited thereto.

[0019] It is to be noted that the present application is basically directed to sensing and collecting specific data (e.g. pressure values, position information of the vehicle, and inclination information of the vehicle) that affect the riding action on a curve when the user rides the vehicle to turn. The skilled person in the art to which the present application pertains should be well aware of how to sense and collect other related data (e.g. vehicle speed, wind speed, temperature, riding distance, road slope, or altitude, etc.), and thus no further description is provided.

[0020] Figure 1 An exemplary schematic diagram of a turning information sensing device 1 according to certain embodiments of the present application is shown. Figure 1 The contents shown are merely for exemplifying the embodiments of the present application, and are not intended to limit the protection scope of the present application.

[0021] As shown in Figure 1 The turning information sensing device 1 basically includes a pressure sensing module 10 and a memory 12, and the pressure sensing module 10 is electrically connected (directly or indirectly) to the memory 12. The pressure sensing module 10 can further include two pressure sensors (e.g. a left pressure sensor 101 and a right pressure sensor 102) respectively arranged at a left grip portion and a right grip portion on opposite sides of the handlebar of the vehicle, for sensing a first left pressure value P1 applied to the left grip portion and a first right pressure value P2 applied to the right grip portion by the user. For example, when the user rides the vehicle to turn, the first left pressure value P1 applied to the left grip portion and the first right pressure value P2 applied to the right grip portion by the user can be sensed by the left pressure sensor 101 and the right pressure sensor 102. Then, the memory 12 can store the first left pressure value P1 and the first right pressure value P2.

[0022] Figure 2 An exemplary schematic diagram of a pressure sensing module according to certain embodiments of the present application is shown. The following description is provided in conjunction with Figure 2 Exemplifying how the two pressure sensors are arranged on the vehicle. Figure 2 The contents shown are merely for exemplifying the embodiments of the present application, and are not intended to limit the protection scope of the present application.

[0023] In particular, the two pressure sensors (i.e., a left pressure sensor 101 and a right pressure sensor 102) of the pressure sensing module 10 can employ various types of pressure sensors. For example, piezoelectric pressure sensors, piezoresistive sensors, or capacitive sensors, but not limited thereto. In this context, the two pressure sensors are described by way of example using piezoelectric pressure sensors. In some embodiments, the two pressure sensors can be pressure sensing patches, in which a plurality of sensing units can be distributed to sense the pressure values of each region. That is, the left pressure sensor 101 and the right pressure sensor 102 can be two pressure sensing patches, and are respectively wrapped on the surfaces of the left handle portion and the right handle portion to sense the stress applied to the pressure sensing patches, thereby generating voltage values. It should be noted that the present application does not limit the arrangement of the pressure sensors. For example, the pressure sensors can also be arranged in the left handle portion and the right handle portion, which will not be described hereinafter.

[0024] The memory 12 can include a first storage device (e.g., a memory) and can store a set of instructions readable by a processor. In some embodiments, in addition to the first storage device, the memory 12 can also include a second storage device (e.g., a hard disk, an optical disk) connected to the processor through an internal I / O channel, using a data buffer to transfer data to the first memory. In some embodiments, in addition to the first storage device and the second storage device, the memory 12 can also include a third storage device (e.g., a USB flash disk, a cloud hard disk), which can also copy data into the second storage device.

[0025] It should be noted that the first left pressure value P1 and the first right pressure value P2 can include the pushing force applied by the user to the left handle portion and the right handle portion. Similarly, the first left pressure value P1 and the first right pressure value P2 can include the pulling force applied by the user to the left handle portion and the right handle portion. Similarly, the first left pressure value P1 and the first right pressure value P2 can include the pushing force and the pulling force applied by the user to the left handle portion and the right handle portion. For example, if the user performs appropriate riding actions (e.g., the same or similar to the riding actions of the coach), when the vehicle is turning left, it should apply a pushing force to the left handle portion and a pulling force to the right handle portion. Conversely, when the vehicle is turning right, it should apply a pulling force to the left handle portion and a pushing force to the right handle portion. The above-mentioned corner riding action is called "countersteering". That is, when the vehicle is about to turn, the user of the vehicle can temporarily change the steering angle direction of the handlebar (e.g., "when turning left, push with the left hand and pull with the right hand" or "when turning right, pull with the left hand and push with the right hand") to tilt the center line of the vehicle to the turning direction, so as to smoothly complete the turning angle.

[0026] Next, after the pressure sensing module 10 senses the first left pressure value P1 and the first right pressure value P2, it can store the first left pressure value P1 and the first right pressure value P2 in the memory 12. Therefore, the first left pressure value P1 and the first right pressure value P2 sensed and stored by the steering information sensing device 1 can be used to analyze and evaluate whether the user's handling of the curve is appropriate. In other words, the first left pressure value P1 and the first right pressure value P2 can be used to determine whether the user has appropriately performed counter-steering to turn.

[0027] Figures 3A-3C A schematic diagram illustrating how a steering information sensing device 1, according to certain embodiments of the present invention, senses a first left pressure value and a first right pressure value is shown. Figures 3A-3C The illustrations shown are for informational purposes only and are not intended to limit the scope of protection of this invention. It should be noted that the circles in the figures indicate the position of the vehicle, and the arrows indicate the riding direction. Furthermore, the first left pressure value P1 and the first right pressure value P2 are based on the thrust exerted by the user on the left and right handlebars, respectively.

[0028] like Figure 3A As shown, when the user rides the vehicle in a straight line, the left pressure sensor 101 senses a first left pressure value P1 of 2176 millivolts (mV), while the right pressure sensor 102 senses a first right pressure value P2 of 2182 millivolts (i.e., the pressure values ​​applied by the user to the left and right grips are not significantly different). Next, referring to 3B, when the vehicle makes a left turn, the left pressure sensor 101 senses a first left pressure value P1 of 3682 millivolts, while the right pressure sensor 102 senses a first right pressure value P2 of 1908 millivolts (i.e., the pressure value applied by the user to the left grip is greater than that to the right grip). Next, referring to 3C, when the vehicle returns to a straight line, the left pressure sensor 101 senses a first left pressure value P1 of 2201 millivolts, while the right pressure sensor 102 senses a first right pressure value P2 of 2190 millivolts (that is, the pressure values ​​applied by the user to the left and right grips are not significantly different). Therefore, it can be determined that the user appropriately performed counter-steering when making a left turn while riding the vehicle.

[0029] In some embodiments, the steering information sensing device 1 may further include a display device electrically connected to the processor, and the display device may be configured on the vehicle (e.g., but not limited to, on the handlebars, dashboard, or other location within the user's line of sight). In some embodiments, the display device may be a light bar (e.g., an LED light bar), a speaker, or other display element, but is not limited thereto. The display device can be used to display the riding motion analysis results.

[0030] In some embodiments, the display device can be two light bars (e.g., a left light bar and a right light bar), each having five light beads. When the pressure sensing module 10 senses the first left pressure value P1 and the first right pressure value P2, the processor can generate a display signal according to the first left pressure value P1 and the first right pressure value P2. Then, the display device can display the first left pressure value P1 and the first right pressure value P2 according to the display signal. For example, when the vehicle is turning left, if the user properly performs counter-steering to turn (e.g., pushing the left handlebar and pulling the right handlebar), a larger pressure value is applied to the left handlebar, and a smaller pressure value is applied to the right handlebar. At this time, the left light bar displays one light bead, and the right light bar displays five light beads. For another example, when the vehicle is turning left, if the user does not properly perform counter-steering to turn (e.g., pushing the left handlebar and pushing the right handlebar) due to nervousness. At this time, since the user performs improper riding actions, the processor does not generate the display signal, and neither the left light bar nor the right light bar displays any light beads.

[0031] In some embodiments, the display device can be a speaker. When the pressure sensing module 10 senses the first left pressure value P1 and the first right pressure value P2, the processor can generate the display signal according to the first left pressure value P1 and the first right pressure value P2. Then, the speaker can emit sound or not emit sound according to the display signal to provide a prompt.

[0032] Figure 4 A schematic diagram of a right front side pressure sensor and a right rear side pressure sensor according to some embodiments of the present application is illustrated. It should be noted that, Figure 4 The right pressure sensor 102 is taken as an example for illustration, but the left pressure sensor 101 substantially corresponds to the right pressure sensor 102. Figure 4 The content shown is only for the purpose of illustrating the embodiments of the present application, and is not intended to limit the protection scope of the present application.

[0033] In some embodiments, the left pressure sensor 101 can further include a left front side pressure sensor (not shown) and a left rear side pressure sensor (not shown), and the left front side pressure sensor and the left rear side pressure sensor can be wrapped around the left handlebar. On the other hand, the right pressure sensor 102 can further include a right front side pressure sensor 102a and a right rear side pressure sensor 102b, and the right front side pressure sensor 102a and the right rear side pressure sensor 102b can be wrapped around the right handlebar. It should be noted that the left front side pressure sensor, the left rear side pressure sensor, the right front side pressure sensor 102a, and the right rear side pressure sensor 102b can be composed of a plurality of sensing units.

[0034] For example, when the user is riding the vehicle to turn, a left front side pressure value (pushing force) applied by the user to the left handlebar portion can be sensed by the left front side pressure sensor, and a left rear side pressure value (pulling force) applied by the user to the left handlebar portion can be sensed by the left rear side pressure sensor. Similarly, a right front side pressure value (pushing force) applied by the user to the right handlebar portion can be sensed by the right front side pressure sensor 102a, and a right rear side pressure value (pulling force) applied by the user to the right handlebar portion can be sensed by the right rear side pressure sensor 102b.

[0035] In some embodiments, the turning information sensing device 1 can further comprise a positioning device and a processor, the positioning device is electrically connected to the processor, and the positioning device can be disposed on the vehicle (for example, but not limited to, under the instrument panel, under the seat cushion). In some embodiments, the positioning device can be a global positioning system (GPS) for tracking and obtaining a position information of the vehicle. The processor can be a programmable special integrated circuit with the ability of operation, storage, output / input, etc., and can accept and process various coded instructions to perform various logical operations and arithmetic operations and output corresponding operation results. The processor can be programmed to interpret various instructions and perform various tasks or programs to complete various actions described in the disclosure. For example, the processor can include a central processing unit (CPU), a digital signal processor (DSP), a microprocessor, and / or a microcontroller, etc.

[0036] When the user rides the vehicle, the positioning device can obtain a plurality of position information of the vehicle as the vehicle moves. Accordingly, the processor can generate a riding path information according to the position information. As mentioned above, in this document, the riding path of the vehicle can be a driving school road or a race track road. For example, when the user rides the vehicle in a driving school, the positioning device can obtain the position information of each position of the vehicle in the driving school road, and generate the riding path information according to the positions.

[0037] Figure 5 A schematic view of an inclination angle of the vehicle according to some embodiments of the present disclosure. Figure 5 The contents shown are only for illustrating the embodiments of the present disclosure, and are not intended to limit the protection scope of the present disclosure.

[0038] In some embodiments, the turning information sensing device 1 can further comprise a tilt sensor electrically connected to the processor, and the tilt sensor can be disposed on the vehicle (e.g., but not limited to, under the dashboard, under the seat cushion). As shown in FIG. 10B, when the vehicle is turning, in order to balance the centrifugal force and the gravity of the vehicle to smoothly turn, an angle θ between the center line L of the vehicle and the normal N of the ground can be formed. Therefore, when the user rides the vehicle to turn, the tilt sensor can be used to sense an angle information (i.e., θ) of the vehicle. Figure 5

[0039] In some embodiments, the memory 12 can store the riding path information and the angle information, which can be used later to analyze and evaluate whether the user's handling condition when riding the curve is appropriate.

[0040] In some embodiments, the processor of the turning information sensing device 1 can establish a riding action model according to the first left pressure value P1, the first right pressure value P2, the riding path information and the angle information. For example, the aforementioned user can be a coach of a driving school. That is, the aforementioned riding action can be performed by the coach. In this case, the turning information sensing device 1 can establish the riding action model by sensing and storing the first left pressure value P1, the first right pressure value P2, the riding path information and the angle information. In addition, in some embodiments, the riding action model can also be pre-established, and a plurality of the riding action models can be established by a large amount of the first left pressure value P1, the first right pressure value P2, the riding path information and the angle information. That is, different position information can correspond to different first left pressure value P1, first right pressure value P2 and the angle information.

[0041] In some embodiments, after establishing the riding action model, the turning information sensing device 1 can further sense the pressure value of the left handlebar portion, the pressure value of the right handlebar portion, a to-be-tested position information and a to-be-tested angle information of the user or another user when the user or another user rides the vehicle to turn, which can be used later to analyze and evaluate whether the user or another user's handling condition when riding the curve is appropriate. In this case, the user can be a student of a driving school. For example, when a student of a driving school rides the vehicle to turn, the pressure sensing module 10 can sense a second left pressure value of the left handlebar portion and a second right pressure value of the right handlebar portion applied by the user according to the left pressure sensor 101 of the left handlebar portion and the right pressure sensor 102 of the right handlebar portion. The positioning device is also used to obtain a to-be-tested position information of the vehicle. In addition, the tilt sensor is also used to sense a to-be-tested angle information of the vehicle.

[0042] ​Accordingly, the processor of the turning information sensing device 1 can determine a riding action analysis result of the user according to the aforementioned riding action model based on the second left pressure value, the second right pressure value, the to-be-measured position information, and the to-be-measured inclination information. In some embodiments, the riding action analysis result can be whether the user performs a proper riding action or not, or whether the user performs a riding action similar to or not similar to the riding action of the coach. In other words, the riding action analysis result can be used to indicate whether the user performs a proper riding action or not.

[0043] In some embodiments, the turning information sensing device 1 can further include a transmission interface electrically connected to the pressure sensing module 10, and the transmission interface can be disposed on the vehicle (for example, but not limited to, under the instrument panel, under the seat cushion). The transmission interface can be used to output the first left pressure value P1 and the first right pressure value P2. In some embodiments, the transmission interface can support wired transmission or wireless transmission (for example, but not limited to, Bluetooth, a proprietary wireless protocol). Specifically, the first left pressure value P1 and the first right pressure value P2 can be output to a data management system (not shown) corresponding to the turning information sensing device 1 through the transmission interface, so as to analyze and evaluate whether the user's handling condition when riding the curve is proper or not. In some embodiments, the first left pressure value P1, the first right pressure value P2, the riding path information, and the inclination information can be output to the data management system corresponding to the turning information sensing device 1 through the transmission interface. In some other embodiments, the second left pressure value, the second right pressure value, the to-be-measured position information, and the to-be-measured inclination information can be output to the data management system corresponding to the turning information sensing device 1 through the transmission interface.

[0044] The above-described embodiments are only used to illustrate some implementation manners of the present application and explain the technical features of the present application, but not used to limit the protection scope and range of the present application. Any change or equivalent arrangement that can be easily completed by any person skilled in the art belongs to the claimed scope of the present application, and the protection scope of the present application is subject to the claims.
