Please refer to Figure 1. The processor 3 is coupled to the drive module 11, the control module 12, and the sensing module 24. The processor 3 can receive the throttle signal and the frequency signal. And control the driving module 11 to drive the vehicle 1 to move with one of the throttle signal and the frequency signal.

The processor 3 can be coupled to a database 31 for storing a power conversion table. The power conversion table can store a number of output powers in different ranges. The output powers correspond to different ranges of Throttle signal and frequency signal. The processor 3 can search the database 31 to obtain an output power from the plurality of output powers, and the output power corresponds to the throttle signal or the frequency signal received by the processor 3. The processor 3 can input the output power to a motor controller, and then use the motor controller to control the drive module 11 to output kinetic energy equivalent to the output power to drive the wheel 13b to rotate. In this embodiment The input commands that the motor controller can accept include RS232, CAN, PWM, and analog voltage. For example, it can be a DC servo motor controller.

For example, when a 5V power supply is provided to the control module 12, the value of the throttle signal received by the processor 3 can vary between 0~1023; among them, when the value of the throttle signal is between 0~ At 250, the output power can be set to 0 to make the drive module 11 appear in an idle state; when the value of the throttle signal is between 251 and 300, the output power can be set to 100% when the drive module 11 is running at full speed. Ten percent; when the value of the throttle signal is between 301 and 350, the output power can be set to 20% of the drive module 11 when it is running at full speed; when the value of the throttle signal is between 351 and 400 , The output power can be set to 30% of the drive module 11 at full speed; when the value of the throttle signal is between 401~450, the output power can be set to the drive module 11 at full speed Forty percent; when the value of the throttle signal is between 451~500, the output power can be set to 50% of the drive module 11 at full speed; when the value of the throttle signal is between 501~ At 550, the output power can be set to 60% of the drive module 11 running at full speed; when the value of the throttle signal is between 551 and 600, the output power can be set to the drive module 11 running at full speed 70% of the time; when the value of the throttle signal is between 601~1023 At this time, the output power can be set to 75% of the drive module 11 when it is running at full speed.

On the other hand, when the value of the frequency signal is less than or equal to 4 times every six seconds, the output power can be set to 0 to make the drive module 11 appear in an idling state; when the value of the frequency signal is between every six seconds When more than 4 times and less than or equal to 5 times, the output power can be set to 10% of the drive module 11 when it is running at full speed; when the value of the frequency signal is greater than 5 times and less than or equal to 6 times every six seconds , The output power can be set to 20% of the drive module 11 at full speed; when the value of the frequency signal is greater than 6 times and less than or equal to 7 times every six seconds, the output power can be set to the Thirty percent of the drive module 11 when it is running at full speed; when the value of the frequency signal is greater than 7 times and less than or equal to 8 times every six seconds, the output power can be set to that when the drive module 11 is running at full speed Forty percent; when the value of the frequency signal is greater than 8 times and less than or equal to 9 times every six seconds, the output power can be set to 50% of the drive module 11 at full speed; when the When the value of the frequency signal is greater than 9 times and less than or equal to 10 times every six seconds, the output power can be set to 60% of the drive module 11 at full speed; when the value of the frequency signal is between every six When the second is greater than 10 times and less than or equal to 11 times, the output power can be set to 70% of the drive module 11 at full speed; when the value of the frequency signal is greater than 11 times every six seconds, the output The power can be set to 75% of the drive module 11 when it is running at full speed.

Please refer to Figure 2, the vehicle power control system of the present invention can control the processor 3 by programming to receive only one of the throttle signal and the frequency signal at the same time. , You can also install a switch 4 to achieve the same functional purpose. In detail, the switch 4 is provided on the carrier 1, and is preferably arranged adjacent to the control module 12. The switch 4 can be a two-to-one switching element, for example: the switch 4 can have a first An input end, a second input end and an output end, the first input end can be electrically connected to the control module 12, the second input end can be electrically connected to the sensing module 24, the output end is electrically connected Is connected to the processor 3, and can be always connected to one of the first input terminal and the second input terminal. In this embodiment, the The output terminal is always connected to the first input terminal, but it is not limited to this.

Please also refer to Figure 3, the vehicle power control system of the present invention may also have a brake module 5, which is provided on the vehicle 1, and preferably adjacent to the control module 12. It is configured that the braking module 5 is coupled to the processor 3 and used to generate a braking signal. When the processor 3 receives the braking signal, and the value of the braking signal is greater than a first threshold, the processor 3 can reset the relative kinetic energy generated by the output power to zero; and, when the processor 3 receives When the braking signal has a value less than the first threshold and greater than a second threshold, the processor 3 can halve the kinetic energy generated by the output power. For example, when a 5V power supply is provided to the brake module 5, the value of the brake signal received by the processor 3 can vary between 1000 and 1023. In this embodiment, the first The threshold value is set to 1015, and the second threshold value is set to 1000, but it is not limited to this.

Specifically, the priority of the brake signal is higher than the throttle signal and the frequency signal, that is, the processor 3 will first confirm whether the brake signal is received, and if the confirmation result is yes, it will be based on the brake signal. The numerical value reduces the relative kinetic energy generated by the output power, so that the vehicle 1 can decelerate linearly; if the confirmation result is no, the processor 3 then adjusts the output of the driving module 11 according to the received throttle signal or frequency signal power.

It is worth mentioning that, in this embodiment, the processor 3 first converts the output power from an analog signal to a pulse width modulation signal, and then inputs it to the motor controller. The pulse width modulation signal The signal range of the output power is 0~5V, and when the input voltage of the output power is greater than 2.5V, the drive module 11 can show forward rotation; and, when the input voltage of the output power is less than 2.5V, the drive module The system 11 can be reversed; and when the input voltage of the output power is 2.5V±200mV, it is the dead point of the driving module 11, and the driving module 11 will not output at this time.

In view of the above, when the frequency of the analog voltage read by the motor controller is greater than the switching frequency (490 Hz) of the processor 3, and the output power is 0, the motor controller will control the The driving module 11 directly stops operating, causing the vehicle 1 to suddenly stop. Therefore, the vehicle power control system of the present invention can also be electrically connected to the processor 3 and the motor controller with an RC low-pass filter circuit, so that the capacitor (47μF) on the RC low-pass filter circuit can be used in the When the output power is 0, the output voltage is output so that the voltage of the output power will not be 0 and far away from the dead point signal, so as to avoid the sudden stop.

With the aforementioned system architecture, before using the vehicle 1, the user can operate the switch 4 to switch the speed control of the vehicle 1 to the control module 12 or the exercise equipment 2. For example, when the exercise equipment 2 is used as the speed control member of the carrier 1, the user can step on the two pedals 21 so that the two pedals 21 can be linked up and down relative to each other, so that the sensed member 242 can interact with each other. The sensing element 241 is located so that the sensing element 241 can sense the sensing element 242; or the sensing element 242 is deviated from the sensing element 241, so that the sensing element 241 cannot sense the sensing element 242. The processor 3 can sense the frequency of the sensed element 242 through the sensing element 241 to calculate the frequency signal of the user using the exercise device 2. Subsequently, the processor 3 can search the database 31 to obtain an output power corresponding to the frequency signal from the plurality of output powers, and the processor 3 can control the driving module 11 to output equal to the output power The kinetic energy to drive the wheel 13b to rotate.

In summary, the vehicle power control system of the present invention is capable of combining the sports equipment with the vehicle and serving as another speed control component besides the control module of the vehicle. The processor uses the control The signal generated by the module or the sports equipment is used as the basis for controlling the drive module to generate the corresponding motor torque. In this way, the user can choose to use the exercise equipment for fitness while achieving the purpose of moving, and when they do not want to exercise, they can use the control module to drive the vehicle to move. In this way, the exercise equipment provided by the present invention When the vehicle is in motion, it has a relatively safe effect.

Although the present invention has been disclosed using the above-mentioned preferred embodiments, it is not intended to limit the present invention. Invention, any person who is familiar with this technique does not deviate from the spirit and scope of the present invention, and makes various changes and modifications relative to the above-mentioned embodiments still belong to the technical scope protected by the present invention.
