Description

Technical Field

[0001] This invention relates to the field of electric-assisted bicycles, and more specifically, to a device and method for preventing accidental activation of the assist function in an E-bike. Background Technology

[0002] Currently, with the assist function activated, e-bikes will move forward as long as the pedaling force exceeds a preset threshold. However, if the user is not riding but pushing or standing, accidentally triggering the assist function could lead to accidents. For example, if a user is pushing an e-bike and the pedal hits their leg or an obstacle on the road, generating a pedaling force exceeding the threshold, triggering the motor assist, the vehicle will suddenly accelerate, causing the user to be pulled and fall, or causing a collision with a pedestrian. Although the probability of these accidents is small, if they do occur, they can cause significant damage. Summary of the Invention

[0019] If the vehicle speed is in the high-speed range or the pressure is greater than the set pressure value, no action will be taken;

[0020] If the vehicle speed is in the medium speed range, when the pedal force increases from below the set pedal force value to above the set pedal force value, the power assist will be limited to no more than level 2 for the first set time period. After the first set time period, the power assist will be released.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. In addition, the technical features of the various embodiments or individual embodiments provided by the present invention can be arbitrarily combined with each other to form feasible technical solutions. Such combinations are not constrained by the order of steps and / or structural composition patterns, but must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0044] Based on the problems in the background technology, the present invention determines whether the E-bike is in a riding state by collecting data from multiple sensors. Based on the riding state of the E-bike and the changing trends of speed and pedaling force, and combined with measures such as limiting the power assist level, the present invention tries to avoid accidents caused by accidental activation of power assist.

[0045] This invention provides a device for preventing accidental activation of the assist function on E-Bikes, such as... Figure 1 As shown, the device includes a wheel speed sensor, a pressure sensor, a pedal force sensor, and a control mechanism. The control mechanism is connected to the wheel speed sensor, the pressure sensor, and the pedal force sensor via wired or wireless means, respectively.

[0046] The system includes a wheel speed sensor for real-time detection of the E-bike's speed; a pressure sensor installed under the seat for real-time detection of the pressure exerted on the seat; a pedal force sensor for real-time detection of the pedal force exerted by the user when pedaling; and a control mechanism for determining whether the E-bike is in a riding state based on the real-time detected speed, seat pressure, and pedal force, as well as determining whether the E-bike's assist level needs to be adjusted, and adjusting the assist level based on safety measures that limit the assist level.

[0047] It is understood that the device for preventing accidental activation of the assist function in E-Bike provided by the present invention includes a wheel speed sensor, a pressure sensor, a pedal force sensor, and a control mechanism, wherein the control mechanism is connected to the pressure sensor via wired or wireless means.

[0048] Wheel speed sensors are a fundamental component of E-Bikes. They are generally based on the Hall effect and can be used to calculate the vehicle speed, i.e., the speed at which the E-Bike is moving forward, by measuring the wheel speed.

[0049] Pressure sensors are typically installed under seats or in other locations to detect the pressure exerted on the seat. Once the pressure exceeds a preset threshold, it is determined that the user is sitting on the seat.

[0050] The pedal force sensor is a fundamental component of the E-Bike, used to detect the torque generated on the bottom bracket when a user pedals the E-Bike.

[0051] The control mechanism includes at least one of a motor controller and an instrument panel. The motor controller controls the output of the motor and is a basic component of the E-Bike. When the motor controller detects that the pedaling force exceeds the preset pedaling force threshold, it will trigger the assist function, drive the motor to rotate, and make the E-Bike move forward. The instrument panel, sometimes called a speedometer, can display information such as speed and assist level, and can also send commands to set the assist level to the motor controller. The instrument panel and the motor controller are connected via wired or wireless means.

[0052] Among them, such as Figure 1 As shown, the control mechanism only includes a motor controller. The motor controller is used to determine whether the E-bike is in riding mode based on the real-time detected vehicle speed, seat pressure and pedal force, and whether the E-bike's assist level needs to be adjusted. It also adjusts the E-bike's assist level based on safety measures that limit the assist level.

[0053] like Figure 2 As shown, another embodiment of an E-Bike device for preventing accidental activation of assist is illustrated. The control mechanism includes a motor controller and an instrument. The instrument is connected to the motor controller via a wired or wireless means. The instrument is used to determine whether the E-bike is in a riding state based on real-time detected vehicle speed, seat pressure, and pedal force, and to determine whether the assist level of the E-bike needs to be adjusted. When the assist level needs to be adjusted, a command to adjust the assist level is sent to the motor controller so that the motor controller can adjust the assist level of the E-bike.

[0054] Understandably, the control mechanism is used to determine whether the E-bike is in a riding state based on the real-time detected vehicle speed, the pressure on the seat, and the pedaling force, and to determine whether the E-bike's assist level needs to be adjusted. It then adjusts the E-bike's assist level based on safety measures to limit the assist level, including: determining that the E-bike is in a riding state when the pressure on the seat exceeds a preset pressure value; otherwise, determining that the E-bike is in a non-riding state; when the E-bike is in a riding state, taking corresponding safety measures to limit the assist level based on the vehicle speed range and the trend of pedaling force changes; and taking no measures when the E-bike is in a non-riding state.

[0055] Among them, when the E-bike is in riding mode, the corresponding safety measures for limiting the power assist level are taken according to the speed range and the trend of pedal force changes, including:

[0056] When riding an E-bike, the speed is divided into high-speed, medium-speed, and low-speed ranges.

[0057] If the vehicle speed is in the high-speed range or the pressure is greater than the set pressure value, no action will be taken;

[0058] If the vehicle speed is in the medium speed range, when the pedal force increases from below the set pedal force value to above the set pedal force value, the power assist will be limited to no more than level 2 for the first set time period. After the first set time period, the power assist will be released.

[0059] If the vehicle speed is in the low speed range, when the pedal force increases from below the set pedal force value to above the set pedal force value, the second set time period delay assistance measure is first adopted, and then the first set time period limit assistance is adopted to be within level 2. After the first set time period, the limit level is released. The second set time period is shorter than the first set time period.

[0060] Understandably, the control mechanism collects data from various sensors in real time and makes a comprehensive judgment on vehicle speed, pressure, and pedaling force. If the pedaling force exceeds the threshold when the vehicle is not being ridden, safety measures such as suspending power assist, delaying power assist, or limiting power assist levels will be taken.

[0061] The criteria for judging sensor data mainly include: if the vehicle speed is high, significantly exceeding the walking speed of a normal person, it is determined that the person is riding; however, it is impossible to judge when the vehicle speed is low. If the pressure exceeds the threshold, it is determined that the person is riding; however, it is impossible to judge when the pressure does not exceed the threshold, because the user may be riding standing up. If the pedal force quickly exceeds the threshold and then quickly drops to a very small value, it indicates that the pedal force at this time is likely to be generated accidentally, and it is determined that the person is not riding.

[0062] The main safety measures that can be implemented include:

[0063] Pause assist means not providing assist regardless of the pedaling force.

[0064] Delayed boost means that when the pedal force exceeds a threshold, boost is not applied immediately. Boost is only applied when the pedal force continuously exceeds the threshold within a certain period of time. This measure is mainly for situations where the pedal force rises and falls rapidly.

[0065] Limiting the assist level means restricting the actual assist of the motor to no more than a lower level, such as limiting it to level 2. If the user sets it to level 3, the motor will provide assistance at level 2.

[0066] Safety measures are time-sensitive. They take effect when vehicle speed and pressure meet certain conditions and pedal force rises from below a threshold to above a threshold. After a certain period, the safety measures automatically expire. These safety measures are implemented flexibly according to different situations; for example, different measures are taken at different vehicle speeds.

[0067] See Figure 3 This invention provides a method for preventing accidental triggering of the assist function on E-Bikes, which mainly includes the following steps:

[0068] Step 1: Real-time monitoring of E-bike speed, seat pressure, and pedaling force when the user pedals the E-bike;

[0069] Understandably, this invention primarily relies on a wheel speed sensor to detect the forward speed of the E-bike, a pressure sensor installed under the E-bike seat to detect the pressure exerted on the seat, and a pedal force sensor to detect the pedal force exerted by the rider on the E-bike pedals.

[0070] Step 2: Based on the real-time detected vehicle speed, seat pressure, and pedal force, determine whether the E-bike is in riding mode and whether the E-bike's assist level needs to be adjusted. Adjust the E-bike's assist level based on safety measures that limit the assist level.

[0071] Specifically, when the pressure on the seat exceeds a preset pressure value, the E-bike is determined to be in riding mode; otherwise, the E-bike is in non-riding mode. When the E-bike is in riding mode, corresponding safety measures are taken to limit the power assist level based on the speed range and the trend of pedal force changes. When the E-bike is in non-riding mode, no measures are taken.

[0072] Specifically, the judgments and measures for preventing untriggered assistance in this invention are implemented by the software of the control mechanism. A specific embodiment of this software is described in detail below. Figure 1 The structure and program flow shown are as follows: Figure 4 As shown.

[0073] The software collects data such as vehicle speed, pressure, and pedal force every 200ms and takes different measures based on different vehicle speeds.

[0074] Vehicle speed is divided into three ranges: high speed, medium speed, and low speed. High speed is greater than 10 km / h, medium speed is between 6 km / h and 10 km / h, and low speed is less than 6 km / h.

[0075] If the vehicle speed is in the high-speed range or the pressure is greater than 30 kgf, no action will be taken;

[0076] Otherwise, if the speed is in the medium speed range, when the pedal force increases from below 4 N*m to above 4 N*m, the power assist will be limited to no more than level 2 within 1 second. That is, when the pedal force exceeds 4 N*m, the power assist level will be limited to level 2, and the restriction will be lifted after 1 second.

[0077] Otherwise, if the vehicle speed is in the low speed range, when the pedal force increases from below 4 N*m to above 4 N*m, a 0.6-second delay assistance measure is first taken, followed by a 1-second limit assistance measure within the second gear. That is, when the pedal force exceeds 4 N*m and lasts for 0.6 seconds, assistance is provided at a gear no higher than the second gear, and the gear restriction is lifted after 1 second.

[0078] Because the safety measures are only valid for a short period, the original measures will remain in effect as long as the vehicle speed changes from one range to another.

[0079] This invention provides a device and method for preventing accidental activation of the assist function on an E-Bike. Based on data collected from multiple sensors, it determines whether the user is in a riding state. Only when the E-Bike is in a riding state, based on the changing trends of speed and pedaling force, and combined with measures such as limiting the assist level, it minimizes the risk of accidents caused by accidental activation of the assist function.
