[0046] The core of the present application is to provide a tidal seat control method, device and system. Before controlling the tidal seat to fold or unfold, it is necessary to determine whether the safety condition is met to avoid injuring passengers. When the number of passengers is less than the first preset number, the tidal seat can be unfolded to provide better comfort for passengers. When the number of passengers exceeds the first preset number, the tidal seat can be folded to increase the standing area so that the vehicle can accommodate more passengers.

[0047] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0048] Figure 1 A flowchart of a tidal seat control method provided by the present application is shown in the figure. The tidal seat control method is applied to a processor of a control device of a tidal seat of a vehicle. The tidal seat control method comprises the following steps.

[0049] S11: determining whether the safety condition of the tidal seat action is met. If yes, go to step S12.

[0050] S12: determining the number of passengers in the vehicle.

[0051] S13: when the number of passengers exceeds the first preset number and a folding signal is received, controlling the tidal seat to fold based on the folding signal.

[0052] S14: when the number of passengers does not exceed the first preset number and an unfolding signal is received, controlling the tidal seat to unfold based on the unfolding signal.

[0053] Traditional urban rail vehicle seats are fixedly installed, and the passenger compartment seats cannot be unfolded and folded during passenger flow peak or other low peak, and the state of the passenger compartment seats cannot be changed according to the actual passenger flow, and passengers cannot be provided with more personalized services. The tidal seat has the functions of folding and unfolding, and can be folded and unfolded according to the actual passenger capacity of the passenger compartment. If the passenger flow is in the peak period, the passenger compartment tidal seat is automatically folded, a larger standing area is provided for passengers, and more passengers can stand in the vehicle compartment. If the passenger flow is in the low peak period, the passenger compartment tidal seat is automatically unfolded, and better riding comfort is provided for passengers.

[0054] In order to improve the safety of the tidal seat during unfolding and folding, the tidal seat needs to meet certain safety conditions before it can be operated, for example, the unfolding and folding of the tidal seat can be controlled only when the vehicle is stationary, so as to improve the safety of passengers riding the vehicle. The intention of the tidal seat is to determine whether the tidal seat is in a folded state or an unfolded state according to the passenger flow, that is, the number of passengers in the vehicle, so the number of passengers in the vehicle needs to be obtained to determine the state of the tidal seat.

[0055] Specifically, when there are more passengers, the tidal seat occupies a larger area, which reduces the standing area and in turn reduces the number of passengers that the vehicle can accommodate, so the tidal seat is folded at this time to reduce the area occupied by the tidal seat, increase the standing area, and increase the number of passengers that the vehicle can accommodate. When there are fewer passengers, the tidal seat can be unfolded to allow passengers to sit down, improving the comfort of passengers riding the vehicle.

[0056] The application provides a control method of a tidal seat, relating to the field of vehicle control, comprising determining whether a safety condition for the tidal seat to act is met (including whether there are passenger seats or standing in the tidal seat area, etc.); determining the number of passengers in the vehicle; when the safety condition is met and the number of passengers exceeds a first preset number, controlling the tidal seat to fold based on a received folding signal; and when the safety condition is met and the number of passengers does not exceed the first preset number, controlling the tidal seat to unfold based on a received unfolding signal. Before controlling the tidal seat to fold or unfold, it is necessary to determine whether the safety condition is met to avoid injuring passengers. Based on the number of passengers, the tidal seat is controlled to fold or unfold, the tidal seat can be unfolded when the number of passengers does not exceed the first preset number to provide better comfort for passengers, and the tidal seat can be folded when the number of passengers exceeds the first preset number to increase the standing area so that the vehicle can accommodate more passengers.

[0057] On the basis of the above embodiments:

[0058] In some embodiments, determining whether the safety condition for the tidal seat to act is met comprises:

[0059] determining whether the driver's room of the vehicle sends an occupancy signal;

[0060] determining whether the vehicle is in a stationary state;

[0061] determining whether there is no passenger seat leaning in a preset area around the tidal seat;

[0062] determining whether there is no passenger standing in an area after the tidal seat is unfolded;

[0063] if the driver's room sends an occupancy signal, the vehicle is in a stationary state, there is no passenger seat leaning in a preset area around the tidal seat, and there is no passenger standing in an area after the tidal seat is unfolded, it is determined that the safety condition of the tidal seat action is met.

[0064] When the driver enters the driver's room and inserts the key, the driver's room will send an occupancy signal to the controller. If the vehicle is not controlled by the driver, it is very unsafe to unfold and fold the tidal seat automatically. In addition, when the vehicle is in a running state, it is very unsafe for passengers to unfold or fold the tidal seat, so it is necessary to determine that the vehicle is in a stationary state, i.e. zero speed.

[0065] If there is a passenger leaning on the unfolded tidal seat, folding the tidal seat at this time may cause the passenger to fall. In addition, if the tidal seat is in a folded state, but there is a passenger standing in the area after the tidal seat is unfolded, it is easy to hit the passenger when the tidal seat is unfolded in the nearby area.

[0066] Specifically, whether there is a passenger near the seat is determined by a shooting device.

[0067] In some embodiments, the vehicle further comprises a shooting device, and the number of passengers in the vehicle is determined, comprising:

[0068] The image in the vehicle is shot by a shooting device arranged on the top of the vehicle;

[0069] The number of passengers in the vehicle is determined according to the image in the vehicle.

[0070] A PIS (Passenger Information System) camera is arranged in the vehicle interior, which shoots the passengers in the vehicle and the tidal seat, and the number of passengers in the vehicle is determined according to the shot image. In addition, the PIS camera also determines whether there is a passenger near the tidal seat. If the tidal seat is leaned by a passenger or there is a passenger in the unfolded area, the tidal seat will not be moved.

[0071] In some embodiments, the vehicle further comprises a weight collecting device;

[0072] The number of passengers in the vehicle is determined, comprising:

[0073] When the number of passengers in the vehicle is less than the second preset number, the number of passengers in the vehicle is determined according to the image in the vehicle, and the second preset number is less than the first preset number;

[0074] When the number of passengers in the vehicle is not less than the second preset number and less than the first preset number, the number of passengers in the vehicle is determined according to the number of passengers collected by the weight collection device, the weight corresponding to the weight collection device, the number of passengers in the vehicle determined according to the image in the vehicle, and the weight corresponding to the image.

[0075] When the number of passengers in the vehicle is not less than the first preset number, the number of passengers in the vehicle is determined according to the number of passengers collected by the weight collection device.

[0076] Considering that when the number of passengers is large, the image determines the number of passengers is not accurate, and when the number of passengers is small, the number of passengers determined by the weight collection device is also relatively inaccurate, the weight collection device is also provided in the application, which determines the number of passengers in the vehicle according to the set body weight and the collected total weight.

[0077] Specifically, taking the second preset number as 80 people, the first preset number as 150 people, and the weight as 50% as an example, when the number of passengers in the passenger compartment is less than 80, the PIS video counting signal is used as the vehicle load signal; when the number of passengers in the passenger compartment is greater than 80 but less than 150, the vehicle load signal is the video counting signal*0.5+air spring load signal*0.5; when the number of passengers in the passenger compartment is greater than 150, the vehicle load signal is air spring load signal*100%.

[0078] In some embodiments, the control device of the tidal seat further comprises a folding switch, a centralized control switch and a remote control module, all connected with the controller, and the tidal seat is controlled to fold based on the folding signal, comprising:

[0079] The tidal seat is controlled to fold when the folding signal sent by the folding switch when being pressed, the folding signal sent by the centralized control switch or the folding signal sent by the remote control module when receiving the folding signal sent by the ground control center through the control line, and it is determined that there is no passenger near the tidal seat.

[0080] Local offline mode control: when it is judged that it is not in the maintenance mode, and the local offline mode is valid, whether there is a remote centralized control signal or not, the tidal seat is controlled according to the local offline mode. When the folding signal is received, the tidal seat is folded; when the unfolding signal is received, the tidal seat is unfolded.

[0081] Remote control mode: when the non-maintenance mode and the local offline mode are determined to be invalid, the tidal seats are controlled according to the remote control mode. When the effective folding signal provided by the control switch or the remote control module (high, the driver's room occupancy signal is valid, the vehicle zero speed signal, the load signal is valid, and the tidal seat area personnel approach signal, the tidal seat is folded and stored, and a larger passenger room standing area is provided for passengers, and the passenger sitting crowded area space is improved.

[0082] In some embodiments, further comprising:

[0083] Upon receiving the maintenance signal, whether the folding signal or the unfolding signal is received, the tidal seats are controlled to be locked, and unfolding or folding is not allowed.

[0084] The folding tidal seat control is divided into remote control, local offline control and maintenance mode control. The maintenance mode has the highest priority, the local offline mode is second, and the remote control mode is at the lowest level. When the maintenance mode is in the maintenance mode, the processor will lock the maintenance mode signal, regardless of whether there is a remote control signal or a local offline mode signal, the tidal seats are not allowed to fold or unfold, and will always remain in the current state until the maintenance mode is released.

[0091] The processor 22 is used to determine that the current safety condition for the tidal seat action is met when the driver's room occupancy switch K01 is closed and the zero speed signal switch K02 is closed.

[0102] In summary, taking the first preset number of 150 people as an example, the control logic of the application is:

[0103] When the passenger number in the passenger compartment is less than 150 and the tide seat area personnel approach signal (D4) are both satisfied, the effective unfolding and turning centralized signal (high level) provided by the S01 tide seat centralized switch (3-4) or the remote control module (D2) + the driver room occupancy signal (K01) is valid (high level) + the vehicle zero speed signal (K02) is valid (high level) are also required to be satisfied, and then the tide seat is allowed to be unfolded and turned down. When the passenger number in the passenger compartment is greater than 150, even if the effective unfolding and turning centralized signal (high level) provided by the S01 tide seat centralized switch (3-4) or the remote control module (D2) + the driver room occupancy signal (K01) is valid (high level) + the vehicle zero speed signal (K02) is valid (high level) + the load signal is valid + the tide seat area personnel approach signal (D4) are all satisfied, the tide seat is not allowed to be unfolded and turned down.

[0104] When the passenger number in the passenger compartment is less than 150 and the tide seat area personnel approach signal (D4) are both satisfied, the effective folding centralized signal (high level) provided by the S01 tide seat centralized switch (1-2) or the remote control module (D2) + the driver room occupancy signal (K01) is valid (high level) + the vehicle zero speed signal (K02) is valid (high level) are also required to be satisfied, and then the tide seat can be allowed to be folded and stored.

[0105] When there is a passenger on the tide seat (the tide seat area personnel approach signal D4 is low), the tide seat is not allowed to be folded and stored or turned down.
