Detailed Description
The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
In the present embodiment, there is provided a method for executing a control instruction that can be executed on an electric vehicle, and fig. 1 is a flowchart of a method for executing a control instruction according to an embodiment of the present invention, as shown in fig. 1, the flowchart includes the following steps:
step S102, receiving a control instruction, wherein the control instruction is used for controlling the electric vehicle to enter a motor control shielding-releasing state from a motor control shielding state;
and step S104, executing the control command under the condition that the electric vehicle is determined to meet the preset condition.
Among other things, the operations described above may be performed by an electric vehicle (including but not limited to an electric motorcycle, an electric bicycle, a moped, etc.), or may be part of an electric vehicle, such as one or more processors in the electric vehicle, or one or more other types of modules. The above-mentioned predetermined condition is actually a condition for ensuring that the electric vehicle is in a state of being installed for driving after the shielding of the motor control is released. In the motor control shielding state, the motor control signals input through the speed control component of the electric vehicle are all invalid signals, namely, the input motor control signals cannot be responded in the motor control shielding state; and under the state that the motor is controlled to be shielded, motor control signals input through the speed control component of the electric vehicle are all effective signals, and under the state that the motor is controlled to be shielded, the rotating speed of the motor can be adjusted according to the input motor control signals.
In addition, it should be further noted that the application scenario of the present invention may be before the electric vehicle is ridden (i.e., the above steps are performed while the electric vehicle is in a stationary state) or during the electric vehicle is ridden (i.e., during the electric vehicle is ridden, the electric vehicle may enter the motor control shielding state, for example, in the case that the P-range function is implemented through the seat, the user leaves the seat during the riding process, and then enters the motor control shielding state, and after entering the motor control shielding state, the above steps may be performed).
Through the embodiment, because after receiving the control command for controlling the electric vehicle to enter the motor control shielding state by the motor control shielding state, the command can not be always executed, but only under the condition that the electric vehicle meets the preset condition, the control command is executed, so that the electric vehicle is effectively prevented from jumping out at a higher speed, therefore, the problem that the electric vehicle in the related technology can directly jump out, and further the injury to a rider, the electric vehicle and the surrounding environment is caused can be solved, and the effect of ensuring the safety of the rider, the electric vehicle and the surrounding environment is achieved.
In an optional embodiment, in the case where it is determined that the electric vehicle satisfies the predetermined condition, executing the control instruction includes: and executing the control command when the motor rotating speed corresponding to the motor control signal input by the speed control component of the electric vehicle is determined to be less than a preset value. In this embodiment, the predetermined value may be a fixed value set in advance, or may be a current motor rotation speed value of the electric vehicle. In addition, it should be noted that the preset value can be flexibly set according to actual conditions, and after the setting is completed, the preset value can be flexibly adjusted. The adjustment of the preset value can be set on an application APP, or a regulation and control template is preset on the electric vehicle and is adjusted through the regulation and control template.
In an optional embodiment, in the case where it is determined that the electric vehicle satisfies the predetermined condition, executing the control instruction includes: and executing the control command when the motor rotating speed corresponding to the motor control signal input by the speed control component of the electric vehicle is determined to be 0. That is to say, when confirming no motor control signal of input on the accuse fast part, namely when accuse fast part is not rotated, go to control the electric motor car again and enter into motor control by motor control shielding state and separate shielding state, under this state, because the motor control signal of accuse fast part input is 0, consequently, the electric motor car can not flee away, and then just can not cause the threat to riding passerby and surrounding environment.
In an optional embodiment, the method further comprises: and under the condition that the electric vehicle is determined not to meet the preset condition, suspending the execution of the control instruction until the preset condition is met. In the present embodiment, when it is determined that the electric vehicle does not satisfy the predetermined condition, the received control instruction may be refused to be executed until the electric vehicle satisfies the predetermined condition. For example, after receiving the control command, it is detected that the motor control signal input through the speed control component of the electric vehicle is too large, and in addition, the electric vehicle is not controlled to enter the motor control shielding-released state from the motor control shielding state, that is, the electric vehicle is still in the stationary state, and only after detecting that the motor control signal input through the speed control component of the electric vehicle is small enough, for example, as small as 0, the control command is executed.
In an optional embodiment, after receiving the control instruction, the method further comprises: and executing a prompting operation under the condition that the electric vehicle is determined not to meet the preset condition, wherein the prompting operation is used for prompting to adjust the control instruction. In this embodiment, after triggering control command, the rider may not realize that the rider has rotated the speed control component, and at this time, the electric vehicle may perform prompt processing, for example, perform voice prompt or ring prompt, or perform text prompt or light prompt on the display screen if the electric vehicle is provided with the display screen. The rider can realize the misoperation and adjust the operation in time, so that the normal riding of the rider is not delayed.
In addition, it should be noted that, in the present invention, the operation of receiving the control instruction may be of various types, for example, the control instruction triggered by a predetermined operation may be received, where the predetermined operation includes detecting that the load state of the electric vehicle is a predetermined load state; and/or receiving the control instruction triggered by pressing a preset button arranged on the electric vehicle. Alternatively, the load state of the electric vehicle may be determined by a sensor. The bearing state of the electric vehicle may include bearing states at a plurality of different positions, for example, the bearing state may be a seat cushion, a pedal, a tire (a front wheel and/or a rear wheel, which may be determined according to a tire pressure value of the tire), a pedal, or some part of a bracket of the electric vehicle (for example, a bracket for supporting the seat cushion). The sensors may be disposed at different positions corresponding to different positions, for example, the sensor may be disposed below the seat cushion, or may be disposed on the pedal instead of below the seat cushion, or on the rotating handles on two sides of the faucet of the electric vehicle, or on the body part in front of the seat cushion, or on the tire, or inside the shock absorber, or in any of these positions, etc. Optionally, the detecting that the loading state of the electric vehicle is the predetermined loading state includes at least one of: detecting that a pressing pressure acting on a seat cushion of the electric vehicle is greater than a first preset value; detecting that the pressing pressure acting on a pedal of the electric vehicle is greater than a second preset value; detecting that the tire pressure value of the tire of the electric vehicle is greater than a third preset value; and detecting that the stepping frequency of the pedals of the electric vehicle is greater than a fourth preset value.
Fig. 2 is a schematic diagram of a part of components of an electric vehicle according to an embodiment of the present invention, in which the component numbered 1 is a pedal, the component numbered 2 is a pedal, and the component numbered 3 is a handlebar stem.
In an optional embodiment, after executing the control instruction, the method further comprises: controlling an indicator lamp (also called as an electric vehicle state indicator lamp) of the electric vehicle to light according to a preset display mode, and controlling the electric vehicle to send out a first preset prompt tone; the indicating lamp is located at other positions on the handlebar of the electric vehicle except for the position of the instrument, or the indicating lamp is located on a handlebar vertical pipe (also called as a handlebar head pipe), namely a supporting rod for supporting a faucet of the electric vehicle. In this embodiment, after the control command is executed, the electric vehicle enters a normal driving state, in which the current state can be indicated by controlling the indicator light of the electric vehicle to light up and controlling the sound emitted by the electric vehicle, for example, the indicator light of the electric vehicle can be controlled to light white constantly and the electric vehicle can be controlled to emit a sound of "popping". In addition, it should be noted that different states of the electric vehicle can be indicated by different display modes of the electric vehicle indicator lamp and different sounds emitted by the electric vehicle. Alternatively, different states of the electric vehicle can be indicated only by different display modes of the electric vehicle indicating lamp or only by different sounds emitted by the electric vehicle
Optionally, the indicator light may be located in at least one of the following positions of the electric vehicle: the inner side of the handle of the electric vehicle; the outer side of the handle of the electric vehicle; the instrument is arranged at a position between the inner side of the handle and the instrument, wherein the instrument is arranged at the middle position of the handle bar of the electric vehicle.
Alternatively, the number of the indicator lamps may be one or more.
Optionally, the indicator light may include: annular pilot lamp, semi-annular pilot lamp, dot matrix type pilot lamp, rectangular shape pilot lamp.
Optionally, the display mode of the indicator light includes at least one of the following: the display color of the indicator light; when the number of the indicator lamps is multiple, the display number of the indicator lamps is large; the display shape of the indicator light.
It can be seen from the above embodiments that when the aforementioned second signal detects that the user is switching to a state ready for driving the electric vehicle, while the speed control member in the first signal is in a state of rotating by a certain magnitude, the electronic control system does not immediately provide high speed control to the motor, but provides the following solution: it must be ensured that the first signal again becomes minimum in order to enter normal use. Besides, it should be noted that, besides the approach scheme, a time delay (for example, set to 5-10 seconds) may be performed to slowly accelerate the rotation speed of the motor from 0 to the motor speed corresponding to the current high data of the first signal. Thereby effectively avoid the easy drunkenness of electric motor car that motor speed control sudden change caused thereby to lead to reducing the risk of security.
