Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

As shown in fig. 1, an automatic locking and power-off system for an electric vehicle comprises:

the signal detection module 10 is used for acquiring speed information, posture information, shaking information and manual operation information of the electric vehicle in an unlocking state;

the judging module 20 is connected with the signal detecting module 10 and used for judging whether the electric vehicle is in an unmanned state or not according to the speed information, the attitude information, the shaking information and the manual operation information which are acquired by the signal detecting module 10;

and the vehicle locking and power off module 30 is connected with the judging module 20 and is used for locking and power off the electric vehicle after the judging module 20 judges that the electric vehicle is in the unmanned state and keeps the unmanned state for exceeding the preset time.

The automatic locking and power-off system for the electric vehicle adopts the signal detection module 10 to acquire speed information, attitude information, shaking information and manual operation information of the electric vehicle in an unlocking state, and judges whether the electric vehicle is in an unmanned state or not by utilizing the judgment module 20 according to the speed information, attitude information, shaking information and manual operation information acquired by the signal detection module 10. If the unmanned driving state exceeds the preset time, the electric vehicle is locked and powered off, and the motor is not provided with any power by twisting the rotating handle again, so that the unlocking operation is required again to be carried out, and the unlocking operation can be released. For example, if the speed of the electric vehicle is 0 within ten continuous minutes, and the electric vehicle does not shake up, down, left, right, front, and back (whether the vehicle shakes is detected by the three-axis acceleration sensor 11, whether the vehicle shakes on the xyz axes is detected, and at least one axial acceleration of the xyz axes changes during shaking), and the vehicle is not toppled or manually operated, the vehicle is considered to be in a static state all the time, and at this time, the motor controller of the electric vehicle is powered off, and the electric vehicle is locked and powered off.

The scheme is mainly used for the situation that the vehicle is possibly stolen when a user leaves and forgets to lock the vehicle, and the anti-theft performance of the electric vehicle can be effectively improved by using the system; the adopted judgment mode is comprehensive, the condition of misjudgment can not be generated basically, a certain preset time is designed, the traffic light intersection can be tolerated or the user can stop in a nursing state in a short time, the vehicle using habit of the user is more met, and the user experience is improved.

The signal detection module 10 includes an acceleration sensor, a wheel movement signal sensor, or a hall signal sensor. The acceleration sensor, the wheel movement signal sensor or the Hall signal sensor can acquire whether the electric vehicle generates acceleration or speed, so that the speed information of the electric vehicle is acquired.

The signal detection module 10 includes a triaxial acceleration sensor 11 for acquiring posture information and/or shaking information of the electric vehicle, where the posture information includes standing information and tilting information of the electric vehicle. As shown in fig. 2, the acceleration sensor and the three-axis acceleration sensor 11 in the signal detection module 10 can both use the same invensense icm20600 chip. If the chip is horizontally arranged, only one gravity acceleration exists on the z axis, if the chip is inclined, the gravity acceleration can be decomposed on the other axis, and the inclination angle rule can be calculated through the acceleration values of the three xyz axes, so that whether the electric vehicle stands or falls is judged. The shaking information includes information about whether the electric vehicle shakes, which is determined by accelerations of three axes of an x-axis, a y-axis, and a z-axis. Sensing shaking is to acquire the acceleration of three axes of an x axis, a y axis and a z axis, calculate the acceleration difference value in a period of time through an algorithm, and consider that shaking is triggered when the acceleration difference value exceeds a preset threshold value.

The signal detection module 10 includes an operation motion sensor 12 for acquiring human operation information of the electric vehicle, including body button operation information or remote control operation information about lighting, whistling generation. The body of the electric vehicle has a plurality of operation actions or switches to be operated by a user, and the operation of the buttons and the switches can be detected by signals, and corresponding operation can be executed only after the detection is finished, such as whistling/turning on of a vehicle lamp, so that whether artificial operation information or remote control operation information exists can be acquired by operating the action sensor 12.

The preset time is 3min-60min continuously. The optimal time can be 5min-10min, the preset time can be selected according to actual needs, the red light waiting time of a common intersection is less than three minutes, and the time is set to be 5min-10min to be more suitable for the light waiting time of an actual electric vehicle or the parking habit under temporary care. The preset time can be realized by connecting the timing module 40 of the locking power-off module 30, the timing module 40 starts timing when the electric vehicle is judged to be in the unmanned state by the judging module 20, and when the timing time of the timing module 40 exceeds the preset time, the locking power-off module 30 works.

As shown in fig. 3, the present disclosure further provides an automatic locking and power-off method for an electric vehicle, including:

s1: acquiring speed information, posture information, shaking information and manual operation information of the electric vehicle in an unlocking state;

s2: judging whether the electric vehicle is in an unmanned state or not according to the acquired speed information, attitude information, shaking information and manual operation information;

s3: and when the electric vehicle is judged to be in the unmanned driving state and the unmanned driving state is kept for exceeding the preset time, locking and power-off operation are carried out on the electric vehicle.

The principle of the above-mentioned electric vehicle automatic locking power-off method and the above-mentioned electric vehicle automatic locking power-off system are not repeated here, and the method mainly lies in the method of judging whether the vehicle is in the unmanned state and the locking and power-off operation is carried out when the vehicle is confirmed to be in the unmanned state, so as to improve the theft-proof property of the vehicle. The electric vehicle includes, but is not limited to, an electric bicycle.

The speed information is specifically speed information of the electric vehicle acquired by an acceleration sensor, a wheel movement signal sensor or a hall signal sensor. The posture information includes standing information and tilting information of the electric vehicle in a three-dimensional space, which are acquired by the three-axis acceleration sensor 11. The shaking information includes shaking information acquired by the triaxial acceleration sensor 11, and the shaking information includes information about whether the electric vehicle is shaken or not, which is judged by the acceleration of three axes, namely, an x axis, a y axis and a z axis. The human operation information includes body button operation information or remote control operation information about the generation of a light on, a whistle.

Judging whether the electric vehicle is in an unmanned state according to the acquired speed information, attitude information, shaking information and manual operation information specifically means that: and when the acquired speed information is kept to be zero, the posture information is displayed as dumping information, the shaking information is displayed without shaking, and the manual operation information is displayed without any manual operation, judging that the electric vehicle is in an unmanned state. The judgment condition of whether the electric vehicle is in the unmanned state is complex, the scheme selects the speed information, the posture information, the shaking information and the artificial operation information from a plurality of elements and respectively judges, the electric vehicle is judged to be in the unmanned state only if all the information meets the requirement of the unmanned state, the condition of misjudgment is avoided, the electric vehicle is judged to be in the unmanned state from the judgment module 20 and starts timing, the whole electric vehicle needs to keep the state for a certain preset time, the vehicle is considered to be in the static state all the time, then the electric vehicle can be subjected to locking and power-off operation, the judgment is accurate, and the pertinence is strong. Similarly, the preset time is 3min to 60min continuously, preferably 5min to 10min, and the preset time can be selected according to actual needs.
