Description

A passenger door control system, method, device and storage medium for a pure electric bus Technical Field

[0001] This invention belongs to the field of vehicle door control, specifically relating to a passenger door control system, method, device, and storage medium for a pure electric bus. Background Technology

[0002] With the widespread application of pure electric buses in the public transportation sector, the passenger door control system has become a key component in ensuring passenger safety and improving vehicle operating efficiency.

[0003] In related technologies, the existing door control system for pure electric buses is mainly controlled by a switch set in the driver's cab. When passengers need to get on or off after the bus stops, the driver turns on the corresponding switch to control the opening and closing of the door. After the passengers get on the bus, the door is closed again. The opening and closing of the door is controlled by a single logic.

[0004] Regarding the aforementioned technologies, buses encounter various different states during operation, and the opening and closing of passenger doors is only operated by the driver. The driver cannot possibly be aware of all situations at all times, which can easily lead to misoperation or untimely response, affecting passenger safety and the riding experience. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a passenger door control system, method, device and storage medium for pure electric buses, which can intelligently control the opening and closing of the doors according to different situations.

[0006] A passenger door control system for a pure electric bus includes:

[0007] The domain controller, body module, and door controller are connected in sequence. The body module is used to receive control commands from the domain controller and convert the control commands into control signals to be transmitted to the door controller.

[0008] The domain controller is also connected to a signal acquisition unit and a door control switch signal acquisition unit. The signal acquisition unit is used to acquire the door opening and closing shielding signal inside the vehicle. When the door opening and closing shielding signal is valid, the switch signal acquired by the door control switch signal acquisition unit is invalid.

[0009] The door controller is also connected to a door enable switch and a passenger door switch. When the door enable switch signal is valid, the passenger door switch signal is valid.

[0010] The domain controller sends control commands to the body module based on the received door opening / closing shielding signal and switch signal. The body module then converts the control commands into control signals and sends them to the door controller to control the opening and closing of the passenger doors.

[0011] Optionally, the door opening / closing shielding signal includes:

[0012] ON signal, vehicle speed signal, disabled access pedal signal, infrared anti-pinch signal, and cabin door signal.

[0013] Optionally, the passenger door includes a front door, a rear door, and a middle door, wherein the middle door is a door for disabled persons to board the vehicle.

[0014] Optionally, the switching signal includes:

[0015] Driver door control switch signal, front door opening switch signal, emergency stop switch signal, diagnostic switch signal, door enable switch signal, and passenger door switch signal.

[0016] A method for controlling passenger doors in a pure electric bus includes:

[0017] Acquire the type of received signal, which includes door opening / closing shielding signal and door control switch signal;

[0018] Based on the signal type, control commands are issued;

[0019] If the signal type is an ON position signal, then the control command issued is to disable the front door opening switch signal;

[0020] If the signal type is a vehicle speed signal and the vehicle speed is greater than the preset speed, then the control command issued is to block the driver's area door control switch signal, the front door opening switch signal and the door enable switch signal.

[0021] If the signal type is a diagnostic switch signal, then the door opening / closing shielding signal is blocked.

[0022] Optionally, if the signal type is a door enable switch signal, then determine whether the door enable switch signal is valid;

[0023] If the door enable switch signal is valid, then the switch signal on the passenger door is valid.

[0024] Optionally, if the signal type is an emergency stop switch signal, then all door opening and closing blocking signals are blocked, and a forced door opening command is issued;

[0025] If the signal type is a disabled access pedal signal, then the middle door closing signal of all switches is blocked;

[0026] If the signal type is an infrared anti-pinch signal, when the infrared anti-pinch signal is valid, the signal source position of the infrared anti-pinch signal is obtained, and the corresponding door closing signal is blocked according to the signal source position. The signal source position includes the front door signal source position, the middle door signal source position, and the rear door signal source position.

[0027] Optionally, if the signal type is a hatch signal, then when the hatch signal is open, all arbitrary door closing signals of all switches are blocked. The hatch includes a charging port hatch, a side hatch, and a rear hatch.

[0028] A terminal device includes a memory and a processor. The memory stores a computer program that can run on the processor. When the processor loads and executes the computer program, it employs a method for controlling passenger doors of a pure electric bus.

[0029] A computer-readable storage medium storing a computer program, which, when loaded and executed by a processor, employs a method for controlling passenger doors in a pure electric bus.

[0030] The beneficial effects of this invention are:

[0031] By using a door enable switch signal, this system ensures that passengers cannot arbitrarily control the opening and closing of the doors. Then, based on door opening / closing blocking signals and door control switch signals collected by a signal acquisition unit, the system controls the opening and closing of the doors. When the door opening / closing blocking signal is active, the signal from the door control switch signal acquisition unit is disabled, preventing arbitrary control of the doors in special scenarios and avoiding unnecessary dangers. When the door control switch signal is active, the system controls the opening and closing of the doors according to different door control signals. This application prevents arbitrary opening and closing of doors in special scenarios from affecting passenger safety. Considering the switching states in various scenarios, it pays special attention to the coordinated control of vehicle status and door operation, such as vehicle speed sensors, wheelchair pedals, infrared anti-pinch devices, and door opening and closing, ensuring safe and intelligent control of passenger doors based on the overall vehicle operating status during driving, parking, or special operations. Compared to traditional control systems that rely on the driver to control the doors via switches in the driver's cab, this system offers faster response times for opening and closing doors. Furthermore, it is safer because it controls the doors based on different operating states, rather than solely relying on the driver. Attached Figure Description

[0032] Figure 1 is a flowchart illustrating a passenger door control system for a pure electric bus according to the present invention. Detailed Implementation

[0033] A passenger door control system for a pure electric bus, as shown in Figure 1, includes:

[0034] The domain controller, body module, and door controller are connected in sequence. The body module is used to receive control commands from the domain controller and convert the control commands into control signals to be transmitted to the door controller.

[0035] The domain controller is also connected to a signal acquisition unit and a door switch signal acquisition unit. The signal acquisition unit is used to collect the door opening and closing shielding signal inside the vehicle. When the door opening and closing shielding signal is valid, the switch signal collected by the switch signal acquisition unit becomes invalid.

[0036] Specifically, a valid signal means that the corresponding action can be performed based on the received signal, while an invalid signal means that even if a signal is received, the corresponding action will not be performed based on the received signal.

[0037] Specifically, after receiving the door opening / closing shield signal and the door control switch signal, the domain controller processes and judges the signal, and sends a command to the body module via CAN communication. After receiving the command, the body module outputs a control signal to the door controller, which then executes the door opening / closing action.

[0038] The door controller also has a feedback function, which will feed back the actual status of the door to the domain controller in real time.

[0039] The door controller is also connected to a door enable switch and a passenger door switch. When the door enable switch signal is valid, the passenger door switch signal is also valid.

[0040] The domain controller sends control commands to the body module based on the received door opening / closing shielding signals and switch signals. The body module then converts the control commands into control signals and sends them to the door controller to control the opening and closing of the passenger doors.

[0041] The door opening and closing shielding signals include the ON position signal, vehicle speed signal, disabled access pedal signal, infrared anti-pinch signal, and cabin door signal.

[0042] Specifically, the ON signal indicates that the entire vehicle is powered on; the vehicle speed signal indicates the vehicle's current speed; the infrared anti-pinch signal prevents injury from the door closing if someone is under or near the door; and the wheelchair access control signal is provided for disabled persons getting in and out of the vehicle. Typically, the wheelchair access control is only installed on the middle door. When the wheelchair access control is extended, it disables the closing signal of all other doors, preventing injury from a sudden door slamming when a disabled person is getting out of the vehicle.

[0043] Door control switch signals include:

[0044] Driver door control switch signal, front door opening switch signal, emergency stop switch signal, diagnostic switch signal, door enable switch signal, and passenger door switch signal.

[0045] Specifically, the driver door control switch signal is obtained through the driver door control switch, the front door opening switch signal is obtained through the front door opening switch, the emergency stop switch signal is obtained through the emergency stop switch, the diagnostic switch signal is obtained through the diagnostic switch, the door enable switch signal is obtained through the door enable switch, and the passenger door switch signal is obtained through the passenger door switch.

[0046] The driver sends the door control switch signal to the domain controller. After receiving it, the domain controller processes and judges the signal, and sends the command to the body module via CAN communication. After receiving the command, the body module outputs a control signal to the door controller, which then executes the door opening and closing action.

[0047] Driver's area door control switch: This switch is usually directly controlled by the driver and is used to manually operate the passenger door.

[0048] The front door opening switch signal is sent to the body module. After receiving the signal, the body module outputs a control signal to the door controller to execute the door opening and closing action.

[0049] Front door opening switch: This switch is typically used by the driver to manually control the front passenger door when getting in and out of the vehicle.

[0050] The door enable switch signal is sent to the door controller. When the door enable switch signal is valid, the switch on the passenger door can operate.

[0051] Passenger door switch signals allow passengers to open or close the doors by pressing a switch. These signals can be located on the vehicle's dashboard or on the vehicle's pillars or handrails.

[0052] The emergency stop switch signal is sent to the domain controller. After receiving it, the domain controller blocks all door opening and closing signals and sends a forced door opening command to the body module via CAN communication. After receiving it, the body module outputs a door opening signal to the door controller to force the door opening action.

[0053] The diagnostic switch signal is sent to the domain controller. Upon receiving the signal, the domain controller blocks the door opening and closing signal. The diagnostic switch is typically used to put the vehicle into a diagnostic fault mode.

[0054] Passenger doors include the front door, rear door, and middle door, with the middle door being the door for disabled passengers to board.

[0055] A method for controlling passenger doors in a pure electric bus includes:

[0056] Acquire the types of signals received, including door opening / closing shielding signals and door control switch signals.

[0057] Specifically, the door opening / closing shielding signal is to prevent the door from opening or closing under special circumstances.

[0058] Control commands are issued based on the signal type.

[0059] If the signal type is ON, the control command issued will be to disable the front door opening switch signal.

[0060] Specifically, the ON signal is sent to the domain controller. When the ON signal is valid, the front door opening switch signal is blocked. The ON signal indicates that the vehicle is fully powered on. At this time, the doors must be kept closed. Even the front door opening switch signal in the driver's cab cannot be used to open the door to prevent personal safety hazards caused by the door opening.

[0061] If the signal type is a vehicle speed signal and the vehicle speed is greater than the preset speed, the control command issued will be to disable the driver's area door control switch signal, the front door opening switch signal, and the door enable switch signal.

[0062] Specifically, in this embodiment, the preset speed is set to 5 km / h. At this time, the vehicle has already started. When the vehicle is running, all doors are not allowed to be opened to prevent accidents from happening to passengers.

[0063] If the signal type is a diagnostic switch signal, then the door opening / closing shield signal is blocked.

[0064] If the signal type is a door enable switch signal, then determine whether the door enable switch signal is valid.

[0065] If the door enable switch signal is valid, then the switch signal on the passenger door is valid.

[0066] If the signal type is an emergency stop switch signal, then all door opening and closing blocking signals will be blocked, and a forced door opening command will be issued.

[0067] If the signal type is a disabled access pedal signal, then the middle door closing signal of all switches should be disabled.

[0068] If the signal type is an infrared anti-pinch signal, when the infrared anti-pinch signal is valid, the signal source position of the infrared anti-pinch signal is obtained, and the corresponding door closing signal is blocked according to the signal source position. The signal source position includes the front door signal source position, the middle door signal source position, and the rear door signal source position.

[0069] Specifically, the front door signal source position, the middle door signal source position, and the rear door signal source position correspond to the front door, middle door, and rear door of the vehicle, respectively.

[0070] If the signal type is a hatch signal, then when the hatch signal is open, all switch signals for any door closing will be blocked. The hatches include the charging port hatch, the side hatch, and the rear hatch.

[0071] Car hatches are special doors on a vehicle, such as charging port hatches, side hatches, and rear hatches. The opening and closing status of these hatches is crucial for the normal operation and maintenance of the vehicle.

[0072] This application also discloses a terminal device, including a memory and a processor. The memory stores a computer program that can run on the processor. When the processor loads and executes the computer program, a method for controlling passenger doors of a pure electric bus is adopted.

For example, the terminal device may also include input / output devices, network access devices, and buses.

Furthermore, the memory can be a combination of internal storage units and external storage devices of the terminal device. The memory is used to store computer programs and other programs and data required by the terminal device. The memory can also be used to temporarily store data that has been output or will be output. This application does not limit this.

[0076] In this terminal device, the passenger door control method for a pure electric bus described in the above embodiments is stored in the memory of the terminal device and loaded and executed on the processor of the terminal device for convenient use.
