Problems solved by technology

[0005] Disadvantages in the application process of the existing electric bicycle speeding protection technology: 1. It is necessary to add a new protection circuit for hardware protection, so as to prevent the speeding phenomenon, which is not easy to implement and increase the cost of the whole vehicle; 2. If the hardware is not directly protected, the Generally, the motor will be forced to stop working only when the motor speed is too high, but this may have caused a safety accident or motor damage; 3. The user needs to restart the electric bicycle to exit the speed protection mode, which is complicated to operate and not convenient; 4. , The scope of application is small, and it is impossible to avoid speeding phenomena such as user misoperation

Embodiment 1

[0043] figure 1 It is a flow chart of an electric bicycle speeding automatic protection method provided by Embodiment 1 of the present invention. This embodiment can be applied to electric bicycles, and the method is executed by the electric bicycle controller. The controller can use software and / or hardware It is realized in a way and is generally integrated in the control equipment of the electric bicycle. The method specifically includes the following steps:

[0044] S101. In the electric mode, monitor the running state of the electric bicycle.

[0045] The operating state of electric bicycles is mainly divided into riding and non-riding states, which state can be identified through various parameter indicators. For example, the indicators of the non-riding state are typically the driving speed and acceleration variation, etc., and the speed and acceleration can be identified by monitoring the motor speed. The non-riding state is also reflected in whether the user contro...

Embodiment 2

[0056] figure 2 It is a method flow chart of a preferred mode of the automatic protection method for electric bicycles provided by Embodiment 2 of the present invention. Based on the foregoing embodiments, this embodiment provides a preferred solution for identifying the non-riding state, specifically in the electric mode Next, monitor the handlebar operation signal and motor speed of the electric bicycle. If the handlebar operation signal is not received within the set time period and the motor speed is less than or equal to the set threshold, it is determined that the operating state is a non-riding state operation , including:

[0057] S1011. When the handlebar operation signal is not received and the motor speed is less than or equal to the set threshold, start the timer and start counting;

[0058] S1012. During the timing process, judge whether the handlebar operation signal of the electric bicycle is received, if not, execute S1014, if yes, that is, if the handlebar o...

Embodiment 3

[0069] image 3 A schematic structural diagram of an electric bicycle controller according to Embodiment 3 of the present invention is shown. The above-mentioned electric bicycle controller includes: a state monitoring module 301, a protection mode entry module 302 and a protection mode exit module 303, each module will be described in detail below.

[0070] The state monitoring module 301 is used to monitor the running state of the electric bicycle in the electric mode;

[0071] The protection mode entry module 302 is used to trigger the electric bicycle to enter the speed protection mode if the running state of the electric bicycle is a non-riding state, wherein the handlebar operation signal input by the user in the speed protection mode is invalid;

[0072] The protection mode exit module 303 is configured to exit the high speed protection mode when receiving an instruction input by the user to end the high speed protection.

[0073] Preferably, the condition monitoring ...

Abstract

The embodiment of the invention discloses a runaway automatic protecting method for an electric bicycle and a controller. The method comprises the following steps: in an electric mode, monitoring the operating state of the electric bicycle; if the operating state is a non-riding state, triggering the electric bicycle to enter a runaway protecting mode, wherein a handle reversing operation signal input by a user in the runaway protecting mode is invalid; and receiving a runaway protection finish command input by the user, escaping the runaway protecting mode. According to the technical scheme disclosed by the invention, whether the electric bicycle enters the runaway protecting mode or not can be automatically judged to achieve an effect of pre-protection and avoid safety accidents or hardware damage, so that runaway protection of the electric bicycle is easily realized without adding the integral cost, and therefore, the safety of operation of the electric bicycle is effectively improved.

Description

technical field [0001] The embodiments of the present invention relate to the overrunning protection technology, in particular to an automatic overrunning protection method and controller for an electric bicycle. Background technique [0002] Electric bicycles are green vehicles that are very suitable for China's national conditions and have great development prospects. With the development of my country's economy, electric bicycles can be seen everywhere in daily life, and the sales volume has maintained a steady growth in recent years. Electric bicycles are not only green and environmentally friendly, but also highly efficient and reasonably priced, and are more and more popular among the general public. However, during the use of electric bicycles, there are more and more speeding phenomena, and the resulting accident rate increases, resulting in property damage and personal injury. The speeding phenomenon refers to the phenomenon that the user loses control of the elec...
