First, before specifically describing the technical solution of the embodiment of the present disclosure, a technical background or a technical evolution context on which the embodiment of the present disclosure is based is described. In general, in the field of online car booking travel, the current technical background is as follows: in the riding process of the users, some users may have the condition of riding with one hand, the condition of riding with one hand is generally found by a traffic police on site and then correspondingly reminded and normalized, and the riding state of all the users cannot be effectively detected in real time by the manual detection mode, so that the probability of safety accidents is increased. Based on the background, the applicant discovers that in some hot spot areas in a map, at least 10% of users may have the problem of single-hand riding in a certain period of time through long-term model simulation research and development and experimental data collection, demonstration and verification, and therefore, how to timely discover and provide the single-hand riding users becomes a technical problem to be solved urgently. In addition, it should be noted that, from the determination of the probability point of 10% and the technical solutions described in the following embodiments, the applicant has paid a lot of creative efforts.

Specifically, the central control device may analyze the acquired user signal, and determine the riding state of the user according to an analysis result. For example, when the user signal includes a heart rate signal, if the heart rate signal is a signal detected by sensors on two handles, it is determined that the riding state is a two-hand grip riding state; if the heart rate signal is only the heart rate signal detected by the sensor on the right handle or only the heart rate signal detected by the sensor on the left handle, determining that the riding state is a single-hand grip riding state; when the user signals comprise temperature signals, if the temperatures detected by the sensors on the two vehicle handles are both greater than a preset temperature threshold value, determining that the riding state is a two-hand grip riding state; if only one sensor on the bicycle handle detects the temperature signal, determining that the riding state is the single-hand grip riding state, or determining that the riding state is the single-hand grip riding state if one temperature of the temperature signals detected by the sensors on the two bicycle handles is less than a preset temperature threshold; or the user signals comprise a heart rate signal and a temperature signal, and the temperatures detected by the sensors on the two vehicle handles are both greater than a preset temperature threshold value, so that the riding state is determined to be a two-hand grip riding state; if the sensors on the two handlebars do not detect any user signal, but the speed of the vehicle is greater than 0, it is determined that the riding state is a two-handle-off riding state, and the like.

According to the riding state detection method, the sensor can be mounted on the vehicle, the user signal is detected in real time through the sensor, and the user signal is analyzed to determine the real-time riding state of the user, so that the unsafe riding states such as the single-hand grip riding state and the double-hand off-handle riding state of the user can be detected quickly and efficiently, measures can be taken for the unsafe riding states, and the probability of unsafe accidents in the riding process of the user is reduced.

In one embodiment, the sensor comprises a heart rate detection sensor and the user signal comprises a heart rate signal. The step of analyzing the user signal and determining the riding state of the bicycle in S200 may include: and analyzing the heart rate signal to determine the riding state.

Specifically, if only be provided with the sensor on the vehicle handlebar hand, and set up the sensor on the vehicle handlebar hand and include rhythm of the heart detection sensor, well accuse equipment can acquire the rhythm of the heart signal that rhythm of the heart detection sensor detected to carry out the analysis to rhythm of the heart signal and confirm that user's the state of riding is both hands handle state of riding, one hand handle state of riding or both hands leave the state of riding. Optionally, the analyzing process may include determining whether the heart rate signal is valid or invalid, and determining the riding state of the user according to the determination result. Optionally, the method for determining whether the heart rate signal is valid or invalid may also be to determine whether the heart rate signal is valid or invalid according to the number of the heart rate signals.

In some scenes, some abnormal behaviors may exist in the riding process of a user, for example, the user holds up glasses, raises hair, pulls a bag and the like, the existing time of the behaviors is often very short, and in order to prevent the behaviors from being judged as riding with one hand by mistake, collected heart rate signals can be screened, and effective heart rate signals can be screened out. As shown in fig. 3, the step of analyzing the heart rate signal and determining the riding state may be specifically implemented by the following steps:

s210, judging whether the heart rate signal is an effective heart rate signal.

In this embodiment, can judge whether this heart rate signal is effective according to the duration of the heart rate signal of gathering, also can judge whether this heart rate signal is effective according to the intensity of this heart rate signal, can also judge whether this heart rate signal is effective according to whether the sensor on left handle and the right handle all gathers the heart rate signal at the same moment, and this application embodiment is not limited to this.

Wherein, the step of judging whether the heart rate signal is an effective heart rate signal in the above S210 may specifically include: if the first duration of the heart rate signal is greater than or equal to a first preset duration threshold, determining the heart rate signal as an effective heart rate signal; and if the first duration of the heart rate signal is less than a first preset duration threshold, determining that the heart rate signal is an invalid heart rate signal.

In this embodiment, when detecting the heart rate signal, the heart rate signal that heart rate detection sensor detected can carry the timestamp, and the duration of heart rate signal, first duration promptly can be confirmed according to the timestamp of a plurality of heart rate signals of gathering in succession. Optionally, the central control device may determine whether the first duration of the heart rate signal is greater than or equal to a first preset duration threshold, and if the first duration of the heart rate signal is greater than or equal to the first preset duration threshold, may determine that the heart rate signal is an effective heart rate signal; otherwise, the heart rate signal may be determined to be an invalid heart rate signal. Optionally, the first preset duration threshold may represent a maximum duration that a single-hand grip of the user is allowed to continue to be ridden in order to handle an abnormal condition in a two-hand grip riding process of the user; for example, handling the exception condition may be the behavior of the user holding glasses with one hand, the user lifting hair with one hand, the user pulling a bag with one hand, and so on.

And S220, if so, analyzing the heart rate signal and determining the riding state.

Specifically, if it is effective heart rate signal to judge the heart rate signal, at this moment, well accuse equipment can carry out the analysis to effective heart rate signal to confirm the state of riding for both hands handle state of riding, one hand handle state of riding or both hands leave the state of riding according to the analysis result. In this embodiment, the central control device may analyze the number and the generating orientation corresponding to the heart rate signals to determine the riding state according to the analysis result. For example, the generating orientation of the heart rate signal may include a left position corresponding to the heart rate signal detected by the heart rate detecting sensor mounted on the left handle of the vehicle and a right position corresponding to the heart rate signal detected by the heart rate detecting sensor mounted on the right handle of the vehicle.

In one scenario, if the heart rate signal includes a first heart rate signal and a second heart rate signal, the first heart rate signal is the heart rate signal collected by the heart rate detection sensor disposed on the left handle of the vehicle, and the second heart rate signal is the heart rate signal collected by the heart rate detection sensor disposed on the right handle of the vehicle, then the heart rate signal is analyzed in the above S220, and the step of determining the riding state may specifically include the following processes: if the first heart rate signal and the second heart rate signal are both effective heart rate signals, determining that the riding state is a two-hand grip riding state; and if the first heart rate signal or the second heart rate signal is the effective heart rate signal, determining that the riding state is the single-hand grip riding state.

It can be understood that if the heart rate signals include a first heart rate signal acquired by a heart rate detection sensor arranged on a left handle of the vehicle and a second heart rate signal acquired by a heart rate detection sensor arranged on a right handle of the vehicle, the central control device can judge whether the first heart rate signal and the second heart rate signal are both effective heart rate signals, and if the first heart rate signal and the second heart rate signal are both effective heart rate signals, the riding state of the user can be determined to be a two-hand grip riding state; otherwise, if one of the first heart rate signal and the second heart rate signal is judged to be the effective heart rate signal, the riding state of the user can be determined to be the single-hand grip riding state. In this embodiment, the method of determining whether the first heart rate signal and/or the second heart rate signal is an effective heart rate signal may be the same as the method of determining whether the heart rate signal is an effective heart rate signal in the above embodiments.

In another scenario, the heart rate sensor may be disposed on the left handlebar and the right handlebar, for example, heart rate detection patches are disposed on the left handlebar and the right handlebar, and when the user holds the left handlebar and the right handlebar simultaneously, the heart rate signal can be detected, and if the user only holds the left handlebar or the right handlebar, the heart rate signal cannot be detected, so that the heart rate signal is analyzed to determine the riding status, which may include: and if the heart rate signal is an effective heart rate signal, determining that the riding state is a double-hand grip riding state.

In this embodiment, because the characteristic of heart rate detection sensor itself, the user need hold two car handles about simultaneously and just can detect the heart rate signal, consequently, when detecting the heart rate signal, can regard as this user to ride for both hands handle at present, and furtherly, can also detect the duration of this heart rate signal, when the duration of this heart rate signal was greater than the time threshold value of predetermineeing, think this heart rate signal as effective heart rate signal, then confirm the state of riding to be both hands handle state of riding.

According to the riding state detection method, when the heart rate signal is detected and is an effective signal, the riding state is determined to be the double-handle riding state.

In one embodiment, the pressure sensor can be used for acquiring the pressure signal acted on the handlebar by the user, and in this way, the pressure signal can be acquired regardless of whether the user directly holds the handlebar or holds the handlebar by wearing gloves, so that the use scene is wider. If the sensor comprises a pressure sensor, the user signal comprises a pressure signal. The step of analyzing the user signal and determining the riding state of the bicycle in S200 may include: and analyzing the pressure signal to determine the riding state.

Specifically, if only be provided with the sensor on the vehicle handlebar hand, and set up the sensor on the vehicle handlebar hand and include pressure sensor, well accuse equipment can acquire the pressure signal that pressure sensor detected to carry out the analysis to pressure signal and confirm that user's the state of riding is both hands handle state of riding, one hand handle state of riding or both hands leave the state of riding. Optionally, the analyzing process may include determining whether the pressure signal is valid or invalid, and determining the riding state of the user according to the determination result. Optionally, the method for determining whether the pressure signal is valid or invalid may also be that whether the heart rate signal is valid or invalid is determined by the number of the pressure signals, and whether the pressure signal is valid or invalid is determined by comparing the pressure signal with a valid information threshold or an invalid information threshold.

In this embodiment, the pressure sensor may be a flexible film pressure sensor, and the flexible film pressure sensor may be used for detecting a pressure signal when a user wears gloves and cannot directly contact the electrodes.

In some scenes, some abnormal behaviors may exist in the riding process of a user, and in order to prevent the behaviors from being judged as riding with one hand by mistake, collected pressure signals can be screened out, and effective pressure signals can be screened out. As shown in fig. 4, the step of analyzing the pressure signal and determining the riding state may be specifically implemented by the following steps:

and S230, judging whether the pressure signal is an effective pressure signal or not to obtain a judgment result.

In this embodiment, whether the pressure signal is valid may be determined according to the duration of the collected pressure signal, whether the pressure signal is valid may also be determined according to the strength of the pressure signal, and whether the pressure signal is valid may also be determined according to whether the pressure sensors on the left handle and the right handle collect the pressure signal at the same time, which is not limited in this embodiment of the application. .

The step of determining whether the pressure signal is the valid pressure signal in S230 may specifically include: if the second duration of the pressure signal is greater than or equal to the first preset duration threshold, determining the pressure signal as an effective pressure signal; and if the second duration of the pressure signal is less than the first preset duration threshold, determining that the pressure signal is an invalid pressure signal.

In this embodiment, when detecting a pressure signal, the pressure signal detected by the pressure sensor may carry a timestamp, and the duration of the pressure signal, that is, the second duration, may be determined according to the timestamps of continuously acquiring a plurality of pressure signals. Optionally, the central control device may determine whether the second duration of the pressure signal is greater than or equal to the first preset duration threshold, and if the second duration of the pressure signal is greater than or equal to the first preset duration threshold, may determine that the pressure signal is an effective pressure signal; otherwise, the pressure signal may be determined to be an invalid pressure signal.

And S240, determining the riding state according to the judgment result.

Specifically, if the pressure signal is the effective pressure signal, then, the central control device can analyze the effective pressure signal, and determine that the riding state is the two-hand grip riding state, the one-hand grip riding state or the two-hand off-handle riding state according to the analysis result. In this embodiment, the central control device may analyze the number and the generating orientation corresponding to the pressure signals to determine the riding state according to the analysis result. Alternatively, the generating direction of the pressure signal may include a left position corresponding to the pressure signal detected by the pressure sensor mounted on the left handle of the vehicle and a right position corresponding to the pressure signal detected by the pressure sensor mounted on the right handle of the vehicle.

In one scenario, if the pressure signal includes a first pressure signal and a second pressure signal, where the first pressure signal is a pressure signal collected by a pressure sensor disposed on a left handle of the vehicle, and the second pressure signal is a pressure signal collected by a pressure sensor disposed on a right handle of the vehicle, the step of determining the riding state according to the determination result in S2400 may specifically include the following steps: if the first pressure signal and the second pressure signal are both effective pressure signals, determining that the riding state is a double-hand grip riding state; and if the first pressure signal or the second pressure signal is an effective pressure signal, determining that the riding state is a single-hand grip riding state.

It can be understood that, if the pressure signals include a first pressure signal acquired by a pressure sensor arranged on the left handle of the vehicle and a second pressure signal acquired by a pressure sensor arranged on the right handle of the vehicle, at this time, the central control device can judge whether the first pressure signal and the second pressure signal are both effective pressure signals, and if the first pressure signal and the second pressure signal are both effective pressure signals, it can be determined that the riding state of the user is the riding state of the grip of the two hands; if one of the first pressure signal and the second pressure signal is judged to be an effective pressure signal, the riding state of the user can be determined to be a single-hand grip riding state. If the pressure signal comprises a first pressure signal or a second pressure signal, and the first pressure signal or the second pressure signal is an effective pressure signal, the riding state of the user can also be determined to be a riding state of the grip of the two hands, under the condition, the pressure signal generated by the left hand or the right hand in the riding process of the user can only be detected, the pressure sensor which cannot detect the pressure signal possibly has a fault at the moment, and at the moment, the pressure sensor is possibly required to be subjected to fault detection and timely reported for repair.

In this embodiment, the method for determining whether the first pressure signal and/or the second pressure signal is the effective pressure signal may be the same as the method for determining whether the pressure signal is the effective pressure signal in the above-mentioned embodiment.

In the riding state detection method, when the pressure signal is detected and is an effective signal, the riding state is determined to be the double-hand grip riding state.

In this embodiment, in the case that the user may drive the switch in the right hand during the riding process, for this case, in this embodiment, if the pressure signal includes the first pressure signal, the step of determining the riding state according to the determination result in S240 may include, as shown in fig. 5:

and S241, if the first pressure signal is an effective pressure signal, detecting whether an electric valve on a right handle of the vehicle is driven.

In this embodiment, the electric door of the vehicle may be disposed on the right handle of the vehicle, at this time, the pressure signal acquired by the central control device only includes the first pressure signal acquired by the pressure sensor disposed on the left handle of the vehicle, and after determining that the first pressure signal is the valid pressure signal, the central control device may detect whether the electric door on the right handle of the vehicle is driven at the time when the first pressure signal is generated. Optionally, the method for detecting whether the electric switch on the right handle of the vehicle is driven may be whether the driving signal generated by the vehicle driving motor can be acquired; if the electric gate is driven, a driving signal can be generated, and if the electric gate is not driven, the driving signal cannot be generated.

And S242, if the switch on the right handle of the vehicle is driven, determining that the riding state is a two-hand grip riding state.

Specifically, if the central control device detects that the switch on the right handle of the vehicle is driven, the switch can drive the motor to drive the vehicle, and meanwhile, the riding state of the user can be determined to be a double-handle riding state; that is, the user places his left hand on the left handle of the vehicle to perform the grip operation, and the user places his right hand on the right handle of the vehicle to perform the door drive operation.

And S243, if the switch on the right handle of the vehicle is not driven, determining that the riding state is a single-hand grip riding state.

Specifically, if the central control device does not detect that the switch on the right handle of the vehicle is driven, the vehicle can still run by inertia at the moment, and meanwhile, the riding state of the user can be determined to be a single-hand grip riding state, that is, the riding state of the user can be determined to be a left-hand grip riding state, and the right-hand grip-free state.

In another embodiment, the central control device may only obtain the pressure signal collected by the pressure sensor on the right handle, and in this embodiment, if the pressure signal includes the second pressure signal, the step of determining the riding state according to the determination result in S240 may include: and if the second pressure signal is an effective pressure signal, determining that the riding state is a single-hand grip riding state.

In this embodiment, the pressure signal acquired by the central control device only includes the second pressure signal acquired by the pressure sensor arranged on the right handle of the vehicle, and the second pressure signal is determined to be an effective pressure signal.

However, the pressure signal acquired by the central control device only includes the second pressure signal acquired by the pressure sensor arranged on the right handle of the vehicle, and the second pressure signal is determined to be an effective pressure signal.

In the riding state detection method, the pressure signals acquired by the pressure sensor on the left handle and the pressure sensor on the right handle are respectively analyzed, the riding state of the user can be identified according to various conditions, the scene flexibility is higher, especially, the pressure signals are acquired by the pressure sensor on the left handle, but when the pressure signals are not acquired by the sensor on the right handle, the riding state of the user is determined by further judging whether the electric switch on the right handle is driven, thereby avoiding the misjudgment of the right hand due to the driving of the electric switch, and the accuracy of the obtained riding state of the user is higher.

In another embodiment, if the pressure signals include a first pressure signal, a second pressure signal and a third pressure signal, the first pressure signal is a pressure signal collected by a pressure sensor disposed on a left handle of the vehicle, the second pressure signal is a pressure signal collected by a pressure sensor disposed on a right handle of the vehicle, and the third pressure signal is a pressure signal collected by a pressure sensor disposed on a seat cushion of the vehicle, the step of determining the riding state in S240 according to the determination result may specifically include the following processes: if the first pressure signal, the second pressure signal and the third pressure signal are all high level signals, determining that the riding state is a double-hand grip riding state; if the first pressure signal or the second pressure signal is a low level signal, the third pressure signal is a high level signal and a switch on the vehicle is driven, determining that the riding state is a single-hand grip riding state; and if the third pressure signal is a low level signal, determining that the vehicle is in a non-riding state.

It can be understood that if the pressure signals include a first pressure signal acquired by a pressure sensor arranged on a left handle of the vehicle, a second pressure signal acquired by a pressure sensor arranged on a right handle of the vehicle, and a third pressure signal acquired by a pressure sensor arranged on a cushion of the vehicle, at this time, the central control device can judge whether the first pressure signal, the second pressure signal, and the third pressure signal are all high-level signals, and if the first pressure signal, the second pressure signal, and the third pressure signal are all high-level signals, it can be determined that the riding state of the user is a two-hand grip riding state; if one of the first pressure signal and the second pressure signal is judged to be a low level signal, the third pressure signal is judged to be a high level signal, and a switch on the vehicle is driven currently, so that the riding state of the user can be determined to be a single-hand grip riding state; whether the first voltage signal and the second voltage signal are high level signals or low level signals, only the third pressure signal is judged to be a low level signal, which can indicate that the user does not sit on the vehicle cushion, and at the moment, the vehicle is determined to be in a non-riding state.

In some scenarios, in order to avoid unsafe accidents occurring in the riding process of the user, before the vehicle is started, whether the riding state of the user and/or the riding sitting posture of the user meet the normal riding specification of the vehicle or not can be determined, and the vehicle is started for the user to normally ride only when the current state of the user meets the normal riding specification of the vehicle. The above method may further comprise: if the riding state is determined to be the two-hand grip riding state before the vehicle is started, controlling the vehicle to be started; if the riding state is determined to be the single-hand grip riding state or the vehicle is the non-riding state before the vehicle is started, the vehicle is forbidden to be started, and first safety reminding information is output and used for reminding a user of riding by using the grips of both hands.

It can be understood that before the vehicle is started, if the central control device determines that the riding state of the user is the two-hand grip riding state, at this time, it can be shown that the current state of the user meets the normal riding specification of the vehicle, and after the user triggers a vehicle starting instruction, the central control device can control the vehicle to be started according to the received vehicle starting instruction. Before the vehicle is started, if the central control device determines that the riding state of the user is a single-handle riding state or the vehicle is in a non-riding state, at this time, it can be shown that the current state of the user does not conform to the normal riding specification of the vehicle, after the user triggers a vehicle starting instruction, the central control device cannot normally respond to the vehicle starting instruction, and at this time, the central control device can prohibit the vehicle from being started. Optionally, the riding sitting posture of the user meets the normal riding specification of the vehicle, which can be understood as that the user is currently sitting on a cushion of the vehicle; the fact that the riding sitting posture of the user does not meet the normal riding specification of the vehicle can be understood that the user does not sit on the cushion of the vehicle currently, namely, the vehicle is in a non-riding state currently.

In some scenes, a heart rate detection sensor and a pressure sensor can be arranged on a handlebar of the vehicle at the same time, a heart rate signal and a pressure signal are detected at the same time, and the riding state of a user is analyzed by combining the two signals. In this embodiment, the sensor includes a heart rate detection sensor and a pressure sensor, and the user signal includes a heart rate signal and a pressure signal. As shown in fig. 6, the step of analyzing the user signal and determining the riding state of the user in S200 may be implemented by the following steps:

and S250, judging whether the heart rate signal is an effective heart rate signal.

Specifically, if the sensor that sets up on the vehicle handlebar hand includes rhythm of the heart detection sensor and pressure sensor, at this moment, can detect the rhythm of the heart signal through rhythm of the heart detection sensor, detect pressure signal through pressure sensor, under this condition, well accuse equipment can judge earlier whether the rhythm of the heart signal that acquires through rhythm of the heart detection sensor is effective rhythm of the heart signal.

The method for determining the riding state of the user according to the pressure signal in this step is the same as the method for determining the riding state according to the pressure signal, where the method is the same as the method in which the central control device only acquires the pressure signal and then determines the riding state according to the pressure signal in the above embodiment, and details are not repeated here.

On the basis of the above embodiment, when it is detected that the user has an unsafe riding state, the user may be appropriately reminded of riding with both hands, and in this embodiment, the above method may further include: if the riding state is a single-hand grip riding state or a double-hand off-grip riding state, outputting safety reminding information; the safety reminding information is used for reminding a user to ride the handle of the two hands.

It should be noted that, if the central control device determines that the riding state of the user is the one-hand grip riding state or the two-hand off-handle riding state, at this time, the central control device may output safety prompting information, and the safety prompting information may be used to prompt the user to change the one-hand grip riding state or the two-hand off-handle riding state into the two-hand grip riding state, so as to ensure the safety of the user in the riding process.

Optionally, when the safety reminding information is output, the safety reminding information output by the central control device may carry a timestamp, and the duration of the safety reminding information, that is, the fourth duration, may be determined according to the timestamps of the continuously output multiple times of safety reminding information. Optionally, the third preset duration threshold may be a self-defined duration threshold, which is not limited in this embodiment. Optionally, the current riding state of the user may be a corresponding riding state when the safety reminding information is output, that is, a single-hand grip riding state or a double-hand off-handle riding state. Optionally, the user information may include personal basic information of the user and cycling state information of the user. Wherein, the high in the clouds can draw the user portrait of the one-hand user of riding according to received user information and the state of riding, can also grade the user behavior of riding through the standard of riding, simultaneously, can also establish the control strategy of riding to the user of riding of one-hand to control user's the number of times of riding, promote the user to change the habit of riding of one-hand. Optionally, the riding specification may include riding state of the user, standard usage habit of the user, normal placement position of the user after using the vehicle, and other information.

In some scenarios, when the user is found to be in an unsafe riding state and the vehicle speed is high, the vehicle can also be controlled to decelerate properly. In this embodiment, the method may further include: if the riding state is a single-hand grip riding state or a double-hand off-grip riding state, acquiring the running state information of the vehicle; if the running state information meets the preset deceleration triggering condition, outputting a deceleration instruction to a braking device of the vehicle; the deceleration command is used to instruct the brake device to perform a deceleration operation.

It should be noted that, if the central control device determines that the riding state of the user is a one-hand grip riding state or a two-hand off-grip riding state, at this time, the central control device may acquire the driving state information of the vehicle through a gyroscope and an accelerometer arranged on the vehicle; the driving state information may be that the vehicle is driving on a flat road at a constant speed, the vehicle is accelerating or decelerating on a flat road, the vehicle is driving on an uphill, and the vehicle is driving on a downhill.

It can be understood that, if the central control device determines that the driving state information meets the preset deceleration triggering condition, the central control device can send a deceleration instruction to the braking device of the vehicle, so that the braking device automatically makes a deceleration operation response, the vehicle executes the deceleration operation, and the driving speed of the vehicle is reduced to within the safe speed, so as to ensure the safety of the user in the riding process. In this embodiment, the preset deceleration triggering condition may be that a downhill angle of the vehicle in the traveling direction is greater than a preset angle threshold, a speed of the vehicle exceeds a preset speed threshold, an acceleration of the vehicle exceeds a preset acceleration threshold, and the like, which is not limited in this embodiment of the application.

Optionally, the output mode of the deceleration reminding signal may be a voice broadcast mode, and may also be a view display mode.

In addition, the method may further include, in addition to the above steps: in the driving process of the vehicle, if the user signal is not acquired, the riding state is determined to be a two-hand-off riding state.

It can be understood that, in the vehicle driving process, if the heart rate detection sensor cannot detect the heart rate signal and the pressure sensor cannot detect the pressure signal, at this time, the riding state of the user can be determined to be a state that the two hands are away from the handle. In addition, if the effective heart rate signal and the effective pressure signal cannot be detected, and the vehicle is in a running state, the heart rate detection sensor and the pressure sensors arranged on the left handle and the right handle of the vehicle are possibly in a fault state, further the standard can be reached for the corresponding vehicle, whether the vehicle has the state in the historical time period or not is obtained, and if the state is not obtained, the riding state of the user can be determined to be a state that the two hands leave the handle for riding. The situation is in an extremely dangerous state, and the central control equipment can continuously output prompt information for reminding a user that the speed limit or the deceleration control cannot be carried out on the vehicle so as to prevent the vehicle from being out of control. In addition, if the effective heart rate signal and the effective pressure signal cannot be detected, and the vehicle is in a static state, at the moment, the vehicle is in a safe state, the central control equipment does not perform any reminding, and the vehicle does not perform any operation.

According to the riding state detection method, the detected heart rate signals and pressure signals can be analyzed to determine the real-time riding state of the user, so that the unsafe riding states of all users can be detected quickly and efficiently, safety prompts are given to the user in time, the user can change the riding state to ensure safe riding of the user, and the probability of unsafe accidents in the riding process of the user is reduced.
