When the electric vehicle is in a shutdown state, the electric vehicle can be started through specific operation (such as long pressing of a startup button), and after the electric vehicle is started, the electric vehicle is in a locked shutdown state and is unlocked and started through a wireless key. And when the code table and the effective key are in a connected state, the electric vehicle is shut down through specific operations (such as long pressing of a shutdown button, long pressing of a shutdown button of a wireless key or a shutdown button of a mobile phone APP).
It should be noted that the shutdown state of the electric vehicle is different from the lock shutdown state. In the shutdown state, the controller and the code table are in the complete shutdown state, and even the whole system is in the power-off state. The lock-up shutdown state can be entered only by a specific operation. And when the vehicle is locked and the vehicle is shut down, the system is partially shut down, wherein the main controller can be in any one of a shut-down state, a standby state, a normal operation state and a partial module operation state (such as a driving motor speed detection circuit and a main controller activation circuit), but partial functions of the code table are in a working state, the wireless key which can be used at the periphery can be continuously detected, and the code table can be verified, connected and communicated with the wireless key, and if a connection signal sent by the wireless key meets a preset connection condition, the main controller can be controlled to be unlocked and the system can be opened in a matched manner.
The code table has a scan detection state, a connection state, a standby state, an off state, and a connection mode state. In the scan detection state, the code table may scan for a connection signal transmitted by the wireless key. And in the connection state, the code table and the valid key are in a normal connection communication state. In the standby state, the code table is not scanned and detected, is not connected with the wireless key, and needs to be activated and then enters a detection scanning state or a closing state after the code table is completely closed. The stopwatch is in a closed state, namely the electric vehicle is in a complete shutdown state, the stopwatch does not work, and the electric vehicle needs to be manually started to be started. Under the connection mode state, the code table is connected with a corresponding wireless key, and the wireless key is used as an effective key of the code table (electric vehicle) after the connection is successful. It should be noted here that if the code table enters the connection mode state, the code table should not scan the connection signal, and of course, if the code table needs to find a new device in the connection state, the connection signal may be scanned.
In the connection mode, the code table can be automatically authenticated or manually authenticated with the wireless keys which can be connected with the periphery, pairing is successful through authentication, and then N wireless keys are selected from the successfully paired wireless keys for connection; the code list and the wireless key can be manually or automatically authenticated through a mobile phone APP or professional matching equipment, and the authentication is not limited specifically here. By this connection mode, the code table can be switched from the detection state to the connection state.
The wireless key comprises a battery and a control device, and the battery is connected with the control device. The control means may be a button activated manually or may be activated by other means, such as a vibration signal, a position signal or an angle signal. The control device can enable the wireless key to continuously send the Bluetooth signal after being activated or to be called as an effective key after the connection is successful, namely, the wireless key is not successfully connected with the code table, but the wireless key and the code table can possibly establish a pairing relationship, certainly, the control device cannot control the starting and stopping of the electric vehicle, and the effective key is successfully connected with the code table, so that the starting and stopping of the electric vehicle can be controlled.
The wireless key has an active transmission state, a connected state, a standby state, an off state, and a connected mode state. And in the working sending state, the wireless key sends a connection signal. And under the connection state, the effective key and the code table are in a normal connection communication state. In the standby state, the wireless key does not send a connection signal, does not communicate with the code meter, and needs to enter a working sending state after being manually activated or enter a closing state after completely closing the wireless key. The wireless key is in a closed state and needs to be manually opened. In the connection mode state, the wireless key and the connectable code table are paired, corresponding connection is carried out according to selection of the code table after pairing, and the wireless key can be used as a valid key of the code table (electric vehicle) after successful connection with the code table. The valid key is called a wireless key in all states except the connected state.
In the electric vehicle start-stop system, the code table can continuously scan the connection signal sent by the wireless key. And when the code table is scanned that the connection signal meets the preset connection condition, the code table is connected with the wireless key. And when the code table is successfully connected with the wireless key, the successfully connected wireless key is used as an effective key for controlling the start and stop of the electric vehicle. The code table and the effective key are kept connected, the effective key sends a first working signal, the code table continuously scans the first working signal, when the code table scans that the first working signal meets a preset first condition, an unlocking starting control signal is sent to the main controller, and the main controller automatically unlocks when receiving the starting control signal and controls the electric vehicle to start. The code table and the effective key are kept connected, the effective key continuously sends a second working signal, and the code table continuously scans the second working signal. And when the code table scans that the second working signal meets a preset second condition, sending a locking shutdown control signal to the main controller, and when the main controller receives the locking shutdown control signal, controlling the electric vehicle to shut down and automatically shut down.
It should be noted that the connection condition may be for an open operating mode or a closed operating mode, where the code table holds a pairing success table, which is a wireless key that has been paired with the code table. Wherein, for the code table in the open working mode, the connection condition may be: the wired key corresponding to the connection signal is not limited to exist in the pairing success table, but should be paired with the code table; for the code table in the closed operating mode, the connection condition may be: the wired key limit corresponding to the connection signal exists in the pairing success table.
Specifically, the connection condition may be defined by the number of wired keys, for example, if the number of wired keys is N (N ≧ 1), then the connection with the wireless key that transmits the connection signal may be performed N times according to the priority, where the specific number of N and the setting of the priority may be determined as the case may be, but to ensure stable control, N is preferably 1.
The first condition and the second condition are corresponding. For example, the first condition includes that the intensity of the first operating signal is greater than or equal to a preset signal intensity threshold, and the second condition includes that the intensity of the second operating signal is less than the signal intensity threshold; or the first condition includes that the distance between the transmission position of the first working signal and the code table is smaller than or equal to a preset signal distance threshold value, and the second condition includes that the distance between the transmission position of the second working signal and the code table is larger than the signal distance threshold value. The first condition and the second condition are not limited to the above-described preset conditions.
The electric vehicle starting and stopping system continuously scans a first working signal through the code table and compares the first working signal with a preset first condition, and can timely generate and send an unlocking starting control signal to the main controller so as to control the electric vehicle to start; and comparing the second working signal with a preset second condition, and sending a locking shutdown control signal to the main controller in time by the code meter so as to control the shutdown of the electric vehicle. The starting or stopping of the electric vehicle is controlled by manual operation after a wireless key is not required to send a connection signal, so that the steps of manual operation are reduced, the problem of low efficiency in starting and stopping control of the electric vehicle is solved, and the starting and stopping control efficiency of the electric vehicle is improved.
In some embodiments, the code table includes a first controller, a first transceiver, and a display device, the first controller being connected to the main controller, the first transceiver, and the display device, respectively.

The electric bicycle is in a normal riding state when abnormal connection conditions (such as communication connection abnormity caused by faults of the code meter or the wireless key) occur, the electric bicycle enters a locking shutdown countdown after being static, the electric bicycle is locked and shut down if the code meter is not connected with an effective key within a preset time, and the safety of the electric bicycle in the riding state can be improved. It should be noted that the number of connections in this step is not limited, i.e., multiple connections may be made within a preset time until the preset time is over.
In some embodiments, under the condition that the connection between the code table and the wireless key fails, the code table can continuously scan the connection signal sent by the wireless key, so that the code table can establish communication connection with the wireless key within the shortest time when the connection signal is rapidly scanned, and the control efficiency of starting and stopping the electric vehicle is improved.
In some embodiments, connecting with the wireless key that sends the connection signal, and using the wireless key that is successfully connected as a valid key, includes: under the condition that a plurality of connection signals exist in the range from the code table to the preset distance, the code table arranges all the connection signals according to the environment parameters, and the connection signals are sequentially connected with the wireless keys for sending the connection signals according to the arrangement sequence; and taking the wireless key which is successfully connected with the code list in priority as a valid key, wherein the environment parameters comprise: any one or more of signal strength, time scanned by the code table, and distance between the code table.
Taking signal strength as an example, the code table scans that a plurality of wireless keys exist in a preset distance range, the code table automatically and sequentially pairs the first, second and third … … Nth detected wireless keys, if none of the wireless keys are successfully paired, the code table re-scans and detects the pairable wireless keys and sequentially pairs again, and the process is circulated until the pairing is successful or the code table is manually controlled to stop detecting and scanning or stopping pairing. When the code table is successfully paired with at least one wireless key, the code table can select N wireless keys for connection based on the fact that the code table is closest to the code table or the connection signal is strongest, so as to determine the valid keys, and accordingly, the code table does not continue to search and detect new wireless keys until the code table is in an unconnected state again.
Taking the time scanned by the code table as an example, the code table automatically performs priority connection on the paired wireless keys detected at the first time, and if the connection is not successful, the paired wireless keys detected at the second and third times … … are sequentially connected, and the process is circulated until the connection is successful or the code table is manually controlled to stop detecting scanning or stopping connection. After the connection is successful, the code table and the wireless key are in a connection communication state, and the code table does not continue to search and detect a new wireless key in the state until the code table is in an unconnected state again.
In some embodiments, the code table stores a pairing success table, and more than one wireless key with successful pairing is stored in the pairing success table; when the code table scans that a plurality of connection signals exist in the preset distance range, in the process of connecting with the wireless key sending the connection signals, the priority of the connection signals associated with the pairing success table is higher than that of the connection signals not associated with the pairing success table.
For example, there are two connection signals passing through the wireless key that are both scanned by the code table, and one of the connection signals is associated with the pairing success table and is preferentially matched with the wireless key. Of course, if there are a plurality of wireless keys associated with the pairing success table, the connection priority between the plurality of wireless keys may be determined with reference to the above-described embodiment based on the environment parameter.
In some embodiments, in the step of connecting with the wireless key that sends the connection signal and using the wireless key that is successfully connected as the valid key, the priority may also refer to the orientation of the wireless device, and other steps may refer to the description related to the above embodiments, that is, it is preferable to connect with the code table using the wireless key that is oriented closest to the preset angle and has completed pairing.
It should be understood by those skilled in the art that various features of the above-described embodiments can be combined in any combination, and for the sake of brevity, all possible combinations of features in the above-described embodiments are not described in detail, but rather, all combinations of features which are not inconsistent with each other should be construed as being within the scope of the present disclosure.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
