Description

Technical Field

[0001] This invention relates to the field of electric vehicle control technology, and in particular to a method for controlling a speed control throttle signal. Background Technology

[0002] Electric bicycles are vehicles that use batteries as auxiliary power and are based on ordinary bicycles, but are equipped with motors, controllers, batteries, throttles, brake levers, and other control components and display instrument systems.

[0003] Traditional electric bicycles are controlled by twisting a throttle. The full travel of the throttle is about 70°, but the actual effective travel in the whole vehicle is about 45°, with the ineffective travel accounting for about 35%, resulting in a poor user experience. If the effective travel is simply increased, there is a risk that the speed control function will fail or the vehicle will run away after being powered on, posing a safety hazard. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a speed-adjusting throttle signal control method. This method detects the initial and full-throttle signal levels of the electric vehicle's throttle during the power-on phase. Based on the detected data, the corresponding minimum and maximum values ​​are adjusted, thereby increasing the effective travel of the electric vehicle's throttle and reducing the proportion of ineffective travel, thus improving the user experience. At the same time, it avoids the risks of power-on failure and runaway, making it safer to use.

[0005] The technical solution of the present invention, a method for controlling a speed control throttle signal, includes the following specific steps:

[0006] S1. The controller detects the initial throttle signal level k1 and the full throttle signal level k2 in real time when it is powered on.

[0007] S2. Compare the signal levels k1 and k2 obtained in S1 with the controller's factory default values;

[0008] S3. Based on the comparison results, the controller automatically adjusts the minimum and maximum values ​​of the throttle speed control signal.

[0009] Preferably, the speed control signal level of the throttle is X-Y.

[0010] Preferably, the controller's factory default value is (X+a)—(Yb).

[0011] Preferably, if k1 is less than X+a, the minimum value of the throttle speed control signal is adjusted to k1+a1.

[0012] Preferably, if k1 is greater than or equal to X+a2, the minimum value of the throttle speed control signal is not adjusted.

[0013] Preferably, if k2 is greater than Yb, then the maximum value of the throttle speed control signal is adjusted to k2-b1.

[0014] Preferably, if k2 is less than or equal to Y-b2, then the maximum value of the throttle speed control signal will not be adjusted.

[0015] Preferably, X is 0.85V, Y is 4.20V, and the deviation is ±0.05V.

[0016] Preferably, a is 0.3V, b is 0.25V; a1 is 0.1V, b1 is 0.15V; a2 is 0.4V, b2 is 0.5V.

[0017] An application of speed control throttle signal control, using the above control method to control the speed control throttle.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects:

[0019] This invention detects the initial and full-throttle signal levels of the electric vehicle's throttle during the power-on phase; and adjusts the corresponding minimum and maximum values ​​based on the detected data. Specifically: if k1 is less than X+a, the minimum value of the throttle speed control signal is adjusted to k1+a1; if k1 is greater than or equal to X+a2, the minimum value of the throttle speed control signal is not adjusted; if k2 is greater than Yb, the maximum value of the throttle speed control signal is adjusted to k2-b1; if k2 is less than or equal to Y-b2, the maximum value of the throttle speed control signal is not adjusted.

[0020] Furthermore, during vehicle operation, the minimum and maximum values ​​of the throttle speed control signal are adjusted in real time according to the above constraints. After adjustment using this method, the effective travel of the electric vehicle's throttle is approximately 52°, and the ineffective travel accounts for approximately 25%, a reduction of 10%, which improves the actual user experience. At the same time, it avoids the risk of power failure and runaway, making it safer to use. Attached Figure Description

[0022] Example 1

[0023] The present invention proposes a speed control throttle signal control method, the steps of which are as follows:

[0024] 1. The controller detects the initial throttle signal level k1 and the full throttle signal level k2 in real time upon power-up; and obtains the initial data, where k1 is 0.80V and k2 is 4.15V.

[0025] 2. Compare the signal levels k1 and k2 obtained in S1 with the controller's factory default values; where the throttle speed control signal level is X—Y; the controller's factory default value is (X+a)—(Yb);

[0026] Based on experience and industry best practices, X is set to 0.85V, Y to 4.20V, with a deviation of ±0.05V.

[0027] The controller's factory default value is set to (0.85+0.3)—(4.20-0.25)V;

[0028] 3. Based on the comparison results, the controller automatically adjusts the minimum and maximum values ​​of the throttle speed control signal;

[0029] After comparison, k1 is 0.80V, which is less than the minimum value (0.85+0.3)V set by the controller at the factory; therefore, the minimum value of the throttle speed control signal should be adjusted to k1+a1, which is (0.80+0.1)V.

[0030] k2 is 4.15V, which is greater than the maximum value (4.20-0.25)V set by the controller at the factory. Therefore, the maximum value of the throttle speed control signal should be adjusted to k2-b1, which is (4-4.15)V.

[0031] In this embodiment, after intelligent adjustment using this solution, the effective travel is approximately 52°, and the ineffective travel accounts for approximately 25%, which is reduced by 10%, thus improving the actual user experience.

[0032] Example 2

[0033] The present invention proposes a speed control throttle signal control method, the steps of which are as follows:

[0034] 1. The controller detects the initial throttle signal level k1 and the full throttle signal level k2 in real time upon power-up; obtains the initial data, where k1 is between (0.85-1.25)V and k2 is between (3.7-4.20)V.

[0035] 2. Compare the signal levels k1 and k2 obtained in S1 with the controller's factory default values; where the throttle speed control signal level is X—Y; the controller's factory default value is (X+a)—(Yb);

[0036] Based on experience and industry best practices, X is set to 0.85V, Y to 4.20V, with a deviation of ±0.05V.

[0037] The controller's factory default value is set to (0.85+0.3)—(4.20-0.25)V;

[0038] 3. Based on the comparison results, the controller automatically adjusts the minimum and maximum values ​​of the throttle speed control signal;

[0039] After comparison, k1 is (0.85-1.25)V, which is greater than or equal to the minimum value (0.85+0.3)V set by the controller at the factory. Therefore, the minimum value of the throttle speed control signal is not adjusted, which is the actual measured value of k1, and its value range is (0.85-1.25)V.

[0040] If k2 is (3.7-4.20)V and is less than or equal to the maximum value (4.20-0.25)V set by the controller at the factory, then the corresponding maximum value of the throttle speed control signal will not be adjusted, which is the actual measured value of k2, and its value range is (3.7-4.20)V.

[0041] In this embodiment, the initial throttle signal level k1 and the full throttle signal level k2 are detected. Since they exceed the adjustment range, the detected initial level k1 and full throttle signal level k2 are used as the minimum and maximum values ​​to avoid the risk of power-on failure and runaway.

[0042] Example 3

[0043] The present invention proposes a speed control throttle signal control method, the steps of which are as follows:

[0044] 1. The controller detects the initial throttle signal level k1 and the full throttle signal level k2 in real time upon power-up; and obtains the initial data, where k1 is (0.85-1.25)V and k2 is 4.15V.

[0045] 2. Compare the signal levels k1 and k2 obtained in S1 with the controller's factory default values; where the throttle speed control signal level is X—Y; the controller's factory default value is (X+a)—(Yb);

[0046] Based on experience and industry best practices, X is set to 0.85V, Y to 4.20V, with a deviation of ±0.05V.

[0047] The controller's factory default value is set to (0.85+0.3)—(4.20-0.25)V;

[0048] 3. Based on the comparison results, the controller automatically adjusts the minimum and maximum values ​​of the throttle speed control signal;

[0049] After comparison, k1 is (0.85-1.25)V, which is greater than or equal to the minimum value (0.85+0.3)V set by the controller at the factory. Therefore, the minimum value of the throttle speed control signal is not adjusted, which is the actual measured value of k1, and its value range is (0.85+0.4)V.

[0050] Since k2 is 4.15V, which is greater than the maximum value (4.20-0.25)V set by the controller at the factory, the corresponding maximum value of the throttle speed control signal should be adjusted to k2-b1, which is (4-4.15)V.

[0051] Example 4

[0052] The present invention proposes a speed control throttle signal control method, the steps of which are as follows:

[0053] 1. The controller detects the initial throttle signal level k1 and the full throttle signal level k2 in real time upon power-up; and obtains the initial data, where k1 is 0.80V and k2 is (3.70-4.20)V.

[0054] 2. Compare the signal levels k1 and k2 obtained in S1 with the controller's factory default values; where the throttle speed control signal level is X—Y; the controller's factory default value is (X+a)—(Yb);

[0055] Based on experience and industry best practices, X is set to 0.85V, Y to 4.20V, with a deviation of ±0.05V.

[0056] The controller's factory default value is set to (0.85+0.3)—(4.20-0.25)V;

[0057] 3. Based on the comparison results, the controller automatically adjusts the minimum and maximum values ​​of the throttle speed control signal;

[0058] After comparison, k1 is 0.80V, which is less than the minimum value (0.85+0.3)V set by the controller at the factory; therefore, the minimum value of the throttle speed control signal should be adjusted to k1+a1, which is (0.80-0.90)V.

[0059] If k2 is (4.20-0.5)V, which is less than or equal to the maximum value (4.20-0.25)V set by the controller at the factory, then the corresponding maximum value of the throttle speed control signal will not be adjusted, which is the actual measured value of k2, which is (3.7-4.20)V.

[0061] This invention provides an application of speed control throttle signal control, using the control methods of Embodiments 1 and 2 to control the speed control throttle of an electric vehicle. After adjustment using this method, the effective travel of the electric vehicle's throttle is approximately 52°, and the ineffective travel ratio is approximately 25%, a reduction of 10%, improving the user's actual experience; at the same time, it avoids the risk of power-on failure and runaway.
