Description

  The present invention relates to a parameter construction control structure for a three-wheeled motorcycle, and more particularly, to a control device for upright stability of a vehicle body and tilt assistance.

In general, motorcycles tend to be dangerous when driving on wet or graveled roads, whether going straight or curving. For this reason, attention has recently been focused on three-wheeled motorcycles. Three-wheeled bikes can slip and reduce the possibility of falling or overturning compared to two-wheeled bikes. Furthermore, because the three-wheeled bike has good stability, when the vehicle body tilts, the three-wheeled bike moves the center of gravity as the vehicle body tilts, providing good assistance for the centripetal force required for the curve.

JP-T-2017-518224

The problem to be solved is that when the body of a tricycle is tilted, the center of gravity moves too much due to the weight of the body of the tricycle, so the center of gravity moves too fast and the rolling is excessive. The body tilts too early or the direction of rotation becomes excessive. Then, operation control becomes unstable. Tilt assistance and body stability are important points that three-wheeled bikes must improve.

From these points, the inventor has actively pursued a solution to improve the above-mentioned drawbacks based on his many years of experience in research and development in this area, and the present invention has finally been completed.

The present invention includes a sensing unit for sensing vehicle dynamics, a trip computer connected to the sensing unit, a control module connected to the trip computer, a tilt assist device connected to the control module, and a vehicle upright stabilizer. The tilt assist device includes an actuator and a shock absorber that adjusts in conjunction with the actuator.
When the vehicle body is tilted by the tilt assist device, after the sensing unit detects the tilt state, the trip computer calculates the necessary amount of damping force, and the control module controls the tilt assist device to adjust the vehicle body. The main feature is not to overly tilt.

The main advantage of the present invention is that when the vehicle is tilted while driving, the tilt assist device and the vehicle body upright stabilizing device maintain the optimum degree of tilt by automatic calculation so that the vehicle body does not tilt excessively. In addition, the posture can be easily restored during driving, and when the vehicle speed decelerates and stops, a control mechanism that makes the vehicle body stand up works to easily maintain the vehicle body upright posture when the vehicle stops driving.

It is a parameter construction system instruction figure of the example of the present invention. It is a control process instruction | indication figure of the Example of this invention. It is an instruction diagram of a sensing signal and a vehicle body tilt state of an embodiment of the present invention.

In order to achieve the above-mentioned object, the present invention provides a control device for upright stability of a vehicle body and tilt assistance. It consists of a sensing unit installed on a three-wheeled motorcycle and detecting the vehicle's dynamics, a trip computer connected to the sensing unit, a control module connected to the trip computer, and a slope connected to both ends of the control module and the two-wheeled connecting wheel of the three-wheeled motorcycle. Includes auxiliary equipment and body upright stabilizer. Among them, the tilt assist device includes an actuator connected to the control module and a shock absorber connected to the actuator for adjustment.

In the tilt assist device, the sensing unit detects a vehicle movement sensing signal and transmits it to the trip computer. The trip computer then calculates the attenuation requirement with the sensed signal. Next, the required amount of damping force is converted to the voltage pulse frequency required by the actuator based on the shock absorber characteristics through the control module. Finally, the actuator is controlled by the control module, the shock absorber is controlled based on the voltage pulse frequency, and a suitable damping force is output and controlled by the shock absorber.

Of these, when the vehicle speed of the three-wheeled motorcycle is 0 or lower than the specific vehicle speed, the trip computer operates the control module to lock the vehicle upright stabilizer, and the three-wheeled motorcycle's vehicle upright posture. Keep the vehicle body from tilting arbitrarily during driving. When the speed of a three-wheeled motorcycle exceeds a specific vehicle speed, the trip computer controls the control module to release the locked state of the upright stabilizer and allows the vehicle body to tilt arbitrarily so as to be suitable for driving.

In order to explain the object, effect, feature, and structure of the present invention in more detail, the following description will be made with reference to examples and examples.

FIG. 1 is an instruction diagram of a control device for upright stability of a vehicle body and assisting in tilting according to a preferred embodiment of the present invention.

FIG. 1 shows a preferred embodiment of the present invention. A tilt assist device 1 for upright stability and tilt assist of a vehicle body is installed on a three-wheeled motorcycle and detects a vehicle dynamics. A trip computer 12 connected to each other, a control module 13 connected to the trip computer 12, and a tilt assist device 14 connected to the control module 13 and the connecting rods of both wheels of the three-wheeled motorcycle are included. Among them, the tilt assisting device 14 includes an actuator 141 connected to the control module 13 and a shock absorber 142 connected to the actuator 141.

The sensing unit 11 is a displacement meter. The displacement meter sets a certain distance range of the movement, which represents the angular range of the tricycle body tilt. When the displacement meter 11 detects that the inclination angle of the three-wheeled motorcycle body is within the range, the trip computer 12 immediately starts to control the control module 13.

Among them, the sensing unit 11 is also an inclinometer that detects a vehicle body tilt angle. The specific range of motion is set by the inclinometer, which represents the angular range of the tricycle body tilt. When the inclinometer detects that the three-wheeled motorcycle body has entered the movable range, the trip computer 12 immediately starts to control the control module 13.

Of these, the actuator 141 is an electromagnet. The control module 13 outputs a specific pulse voltage to the electromagnet, and further controls the magnitude of the damping force of the shock absorber 142 by the electromagnet.

Among them, the shock absorber 142 includes a variable valve 1421 and a damping 1422 connected to the variable valve 1421. The actuator 141 controls the opening / closing width of the variable valve 1421, the damping 1422 connected to the variable valve 1421 produces different levels of damping force, and the three-wheeled motorcycle has the most suitable damping force at a tilt angle within a certain range. Prevent excessive tilting of the tricycle.

Among them, the control module 13 and the two-wheel connecting rod of the three-wheeled motorcycle further connect the vehicle body upright stabilizer 15. The sensing unit 11 detects the front wheel turning angle and the vehicle body inclination angle of the three-wheeled motorcycle, sends an angle sensing signal to the trip computer 12, and the trip computer 12 operates the control module 13 to lock the vehicle body upright stabilizer 15. Alternatively, unlock operation is performed to help drive when decelerating or stopping a signal, and stable vehicle upright control is performed.

The operation of the parameter construction system 1 is as follows. First, the signal transmitted by the sensing unit 11 is received by the trip computer 12, and the sensing signal is the displacement distance of the displacement meter, the inclination angle of the inclinometer, or other numerical values detected by the sensing unit. Based on the data, the necessary amount of damping force for preventing the vehicle body from being tilted excessively is calculated. Subsequently, the control module 13 converts the required amount of damping force, the known damping 1422 characteristic, and the electromagnet characteristics (for example, damping force-velocity characteristic, electromagnet attraction force-distance characteristic, electromagnet attraction force-power characteristic), and further the actuator A voltage pulse frequency for controlling the magnitude of the power 141 is obtained. The control module 13 controls the actuator 141 at the voltage pulse frequency. The actuator 141 controls the opening / closing width of the variable valve 1421 and further controls the magnitude of the damping force output from the damping 1422.

FIG. 2 is a control device instruction diagram of the vehicle upright stability and tilt assist stability according to a preferred embodiment of the present invention.

The operation of the vehicle body upright stabilizer and the tilt assist stabilizer according to the preferred embodiment of the present invention includes the following operation steps.
Among them, the operation of the tilt assisting device is the next steps A1 to A4. In order of step A1, the sensing unit detects a vehicle movement sensing signal and transmits it to the trip computer. In step A2, the trip computer calculates the required amount of damping force with the sense signal, and transmits the required amount signal of the damping force to the control module. In step A3, the control module converts the required amount of damping force into the voltage pulse frequency required to control the actuator based on the characteristics of the attenuator. Further, the actuator is controlled based on the voltage pulse frequency. In step A4, the actuator controls the corresponding damping force generated by the shock absorber to prevent the vehicle body from being excessively tilted during driving.

FIG. 3 is a sensing signal of the sensing unit according to the embodiment of the present invention and a vehicle body tilt state instruction diagram. The sensing unit of FIG. 3 will be described as a displacement meter.

Among them, in step A1, the sensing unit detects a vehicle movement sensing signal and transmits it to the trip computer. The sensing signal is a voltage output generated by the displacement distance of the displacement meter, an inclination angle of the inclinometer, or other numerical value detected by the sensing unit. In this embodiment, the sensing signal detected by the displacement meter is generated by the displacement distance. The voltage output will be described.

Following the above, before starting step A1, first, the maximum displacement under displacement is set based on the vehicle maximum tilt angle. As shown in FIG. 3, the output voltage when the vehicle is upright is X (volts). The displacement meter outputs X (volts) plus or minus a specified range and moves straight forward, and the trip computer is not linked to the control module. If the vehicle body starts persistent rolling and the displacement meter output voltage range is between A and A '(volts) or between B and B' (volts), the trip computer starts step A2.

Among them, in step A3, the control module converts the voltage pulse frequency necessary to control the actuator based on the known damping characteristics and the necessary amount of damping force, and further controls the actuator based on the voltage pulse frequency. To do. The above-mentioned known damping characteristics and electromagnet characteristics (for example, damping force-velocity characteristics, electromagnet attracting force-distance characteristics, electromagnet attracting force-power characteristics) are the damping force-velocity characteristics, electromagnet attracting force-distance characteristics, electromagnet attracting force. -Including power characteristics.

Among them, in Step A4, the actuator controls the corresponding damping force generated by the shock absorber, and prevents the vehicle body from being excessively tilted during driving. The actuator controls the opening and closing width of the variable valve to control the magnitude of the damping force output by the damping, and the three-wheeled motorcycle produces the optimum damping force at an oblique angle within a certain range. Return to the original.

Next, the operation of the vehicle body upright stabilizer is the following steps B1 to B2, and in order as step B1, when the vehicle speed of the three-wheeled motorbike is 0 or lower than the specific vehicle speed (the specific vehicle speed in this embodiment is a trip computer). The trip computer controls the control module to lock the vehicle upright stabilizer and maintain the vehicle upright of the three-wheeled motorcycle to make it optional during operation. Make sure that the body does not tilt. As step B2, when the speed of the three-wheeled motorcycle exceeds a specific vehicle speed (in this embodiment, the trip computer is set to be greater than 5 km / hr), the trip computer controls the control module to lock the vehicle upright stabilizer. The car body tilts arbitrarily to release the state and drive.

As a supplement to the above, as the step B1, when the vehicle body upright stabilizer is in the locked state, it mainly automatically forms the vehicle body upright state, and the vehicle body does not tilt, thereby further enhancing the stability of the vehicle body upright. For example, when the vehicle stops at a red light, driving stops from deceleration, so the foot does not have to be fixed to the vehicle body, or does not have to be fixed to the middle column or the side column. Since the vehicle upright stabilizing device operates automatically when the vehicle upright stabilizing device operates and the vehicle upright stabilizing device operates, the vehicle body upright stabilizing device cannot tilt the vehicle body, and is more stable when driving and is more convenient. In Step B2, when the engine is running and the speed exceeds 5 km / hr when the signal is green, the upright stabilizer is unlocked, and when driven, the body is tilted freely and recovered to the three-wheeled motorcycle running state. To do.

Among them, the sensing unit further detects the front wheel turning angle and the vehicle body inclination angle of the three-wheeled motorcycle. Further, an angle detection signal is sent to the trip computer, and the trip computer operates the control module to lock or unlock the upright stabilizer. For example, when the trip computer is set to a front wheel turning angle of -10 degrees to 10 degrees or a vehicle body inclination angle of -10 to 10 degrees, lock operation control is performed on the vehicle body upright stabilizer. The aforementioned front wheel turning angle and the vehicle body tilt angle range have only been described with examples. When the vehicle is operated to decelerate or stop the signal in this way, the stable vehicle upright control and the control for releasing the lock operation are canceled immediately if the vehicle speed exceeds 5 km / hr.

From the above, the operation of the vehicle body upright stabilizer of this embodiment is as shown in Table 1.

The parameter construction control structure for upright stability and tilt assist of the vehicle body of the present invention is not possible with currently known technologies in the similar technical field, and has the following advantages.

The tilt assist device generates an optimal damping force after automatic calculation, so that the vehicle body does not tilt excessively and can be easily restored during operation.

The vehicle upright stability control automatically provides the vehicle upright stability control when the vehicle is stopped with the vehicle speed gradually lowered, and when the operation is stopped, the vehicle upright posture is easily maintained.

Therefore, the present invention is excellent in inventive step and practicality among similar products. At the same time, this kind of structural technology data in Japan and overseas has not been seen, and the approximate structure of the present invention has not been found. Therefore, since the present invention meets the application requirements of “creativity”, “match industrial utility” and “inventive step”, it applies for utility model registration.

The above is only a preferred embodiment of the present invention, may be an application of the present invention, and all other structures having the same effect are included in the scope of the claims of the present invention.
