Description

Technical Field

[0001] This invention belongs to the field of bus passenger door control technology, specifically relating to a bus passenger door control device and method based on the driver's intention. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Currently, passenger door control systems for city buses and long-distance coaches typically consist of core components such as a passenger door anti-pinch control box, a door pump solenoid valve, and a door pump. The driver operates the door control rocker switch, outputting an open signal. This signal is received by the passenger door anti-pinch control box. After confirming the signal's validity, the anti-pinch control box activates the door pump solenoid valve, which in turn drives the door pump to open the door.

[0004] However, with the rapid development of automotive electronics technology, the types of external electrical devices installed in buses are increasing, such as CAN bus node modules, intelligent terminals, tire pressure monitoring systems, and lane departure warning systems. In complex operating environments, these devices may generate electromagnetic interference or erroneous pulse signals at their signal output terminals, potentially sending interference signals to external circuits that resemble the door opening signal waveform. Traditional passenger door anti-pinch control boxes are designed only to detect the presence or absence of a signal, failing to effectively distinguish the source and intent of the signal. Upon receiving such a false trigger signal, they are treated as a legitimate door opening command, automatically opening the passenger door without any driver intervention—a false door opening incident.

[0005] If a door is accidentally opened while the vehicle is traveling at high speed, it will pose an extremely serious safety hazard, potentially even throwing passengers out of the vehicle and causing a major traffic accident. Existing technology can employ speed-based door lock control schemes, but their control logic is usually quite simple and cannot fundamentally solve the problems of signal source contamination and physical isolation. They also lack effective protection against reverse-flowing power signals caused by malfunctions in other components. Therefore, accurately identifying the driver's true intention to open the door and fundamentally preventing accidental door opening caused by external interference is a pressing problem that needs to be solved. Summary of the Invention

[0006] To address the aforementioned issues, this invention proposes a bus passenger door control device and method based on driver intent. It uses the driver's actual intention to open the door as an independent, high-priority judgment condition, achieving absolute control over passenger door opening through physical-level circuit isolation. The passenger door control system is only "authorized" to execute the door opening action when the driver has a clear intention to open the door and the vehicle is in a safe condition. This fundamentally solves the problem of passenger doors automatically opening during vehicle operation, effectively ensuring the safety of passengers inside the vehicle. Through dual control logic and physical isolation, it ensures that the door only opens when the driver's intention is clear and it is safe, effectively eliminating the risk of accidental opening of passenger doors while the vehicle is in motion.

[0007] According to some embodiments, the first aspect of the present invention provides a bus passenger door control device based on driver intent, employing the following technical solution: A bus passenger door control device based on driver intent, comprising: The passenger door actuator includes a door pump and a door pump solenoid valve for controlling the operation of the door pump; The passenger door anti-pinch control box is used to output a door pump control signal to the door pump solenoid valve after receiving a door opening trigger signal; The door pump solenoid valve relay has its normally open contact connected in series between the passenger door anti-pinch control box and the door pump solenoid valve. The driver intent acquisition unit is used to acquire mechanical switch signals that indicate the driver's intent to open the passenger door; The passenger door auxiliary controller is connected to the coils of the driver intention acquisition unit and the door pump solenoid valve relay, respectively. After receiving the mechanical switch signal from the driver intention acquisition unit, it controls the coil of the door pump solenoid valve relay to be energized, so that the normally open contact of the door pump solenoid valve relay is closed. After a preset delay, it outputs the door opening trigger signal to the passenger door anti-pinch control box.

[0008] As a further technical limitation, the driver intent acquisition unit includes at least a driver door control rocker switch, an outside door button switch, a remote key receiving module, and an emergency valve switch; the input terminal of the passenger door auxiliary controller connected to the driver intent acquisition unit is configured to receive only switching signals generated by mechanical connection or disconnection.

[0009] As a further technical limitation, the bus is equipped with several passenger doors, and each passenger door corresponds to a door pump solenoid valve relay.

[0010] Furthermore, after the passenger door auxiliary controller receives the main valve open signal indicating that all passenger doors are open, it simultaneously controls the coils of all door pump solenoid valve relays to be energized, and after a preset delay, outputs an opening trigger signal to the passenger door anti-pinch control box corresponding to each passenger door.

[0011] As a further technical limitation, the passenger door auxiliary controller includes a vehicle speed signal acquisition unit for real-time acquisition of the vehicle's current speed; when the current vehicle speed is greater than a preset safe vehicle speed threshold, the passenger door auxiliary controller receives a signal sent by the driver intention acquisition unit, prohibits the control of the coil of the door pump solenoid valve relay to be energized, and prohibits the output of the door opening trigger signal.

[0012] Furthermore, when the current vehicle speed is less than or equal to a preset safe vehicle speed threshold, the passenger door auxiliary controller supplies power to the driver door control rocker switch, making the door opening signal output by the driver door control rocker switch valid.

[0013] As a further technical limitation, the passenger door auxiliary controller also includes a door opening suppression signal acquisition unit for receiving door opening suppression signals from the vehicle controller or other safety systems; when the passenger door auxiliary controller receives the door opening suppression signal, it prohibits the coil of the door pump solenoid valve relay from being energized and prohibits the output of the door opening trigger signal.

[0014] According to some embodiments, a second aspect of the present invention provides a bus passenger door control method based on driver intent, which adopts the bus passenger door control device based on driver intent provided in the first aspect, and employs the following technical solution: A method for controlling bus passenger doors based on driver intent, comprising: The passenger door auxiliary controller monitors the mechanical switch signals generated by the driver's intention acquisition unit in real time. When a mechanical switch signal is detected, the passenger door auxiliary controller determines whether the current vehicle status meets the preset safe door opening conditions. When the safe door opening conditions are met, the coil of the door pump solenoid valve relay controlled by the passenger door auxiliary controller is energized, the normally open contact closes, and the physical connection line between the passenger door anti-pinch control box and the door pump solenoid valve is connected. After the control relay coil is energized and a preset delay time has elapsed, the passenger door auxiliary controller outputs an opening trigger signal to the passenger door anti-pinch control box. The passenger door anti-pinch control box responds to the door opening trigger signal and outputs a door pump control signal. The output door pump control signal is transmitted to the door pump solenoid valve through the normally open contact of the closed relay, driving the door pump to open the passenger door, thus realizing bus passenger door control based on the driver's intention.

[0015] As a further technical limitation, the safe door opening conditions include the vehicle speed signal obtained from the vehicle CAN bus being lower than a preset safe vehicle speed threshold, and no other door opening suppression signals being received.

[0016] As a further technical limitation, a bus passenger door control method based on driver intent also includes door closing control. That is, when the passenger door auxiliary controller receives a door closing signal, it controls the coil of the door pump solenoid valve relay to be energized, so that the normally open contact is closed. During the door closing process, if the passenger door anti-pinch control box outputs a door pump control signal due to the anti-pinch function, the output door pump control signal is transmitted to the door pump solenoid valve through the closed normally open contact of the relay to realize the anti-pinch reverse opening function.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention fundamentally solves the problem of accidental door opening caused by external interference signals through a dual insurance mechanism of "driver intent confirmation + physical circuit isolation". Any signal that has not been confirmed by the driver intent acquisition unit cannot directly drive the door pump. When other components malfunction and reverse current flows into the signal line, the current cannot reach the door pump because the door pump solenoid valve relay is in the open state, thus achieving perfect electrical isolation, providing dual safety protection, eliminating accidental door opening, ensuring pure signal source, and accurate intent recognition.

[0018] By limiting the driver intent acquisition unit to a purely mechanical switch, this invention ensures the absolute purity of the trigger signal for the passenger door auxiliary controller, avoids false signals caused by electronic component failure or interference, and greatly improves the accuracy of intent recognition.

[0019] This invention combines vehicle speed signals and door opening suppression signals to intelligently determine the vehicle status, ensuring that passenger doors can only be opened at a safe low speed or when stationary. This completely eliminates the major safety hazard of passengers being thrown out of the vehicle due to accidental door opening during high-speed travel. It can be added or modified as an additional module to the existing bus passenger door control system by disconnecting the original control circuit and connecting it to relay contacts, and adding an auxiliary control box. It requires minimal modification to the original vehicle system, has strong compatibility, and is easy to promote and implement. Attached Figure Description

[0027] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0028] Example 1 Embodiment 1 of the present invention introduces a bus passenger door control device based on driver intent.

[0029] like Figure 1As shown, in this embodiment, the original wiring between the passenger door anti-pinch control box and the door pump solenoid valve is disconnected and connected to the normally open contacts of the relays, thus physically isolating the wiring between the passenger door anti-pinch control box and the door pump solenoid valve. The circuit connection between the passenger door anti-pinch control box and the door pump solenoid valve is only connected when the relay is energized. At the same time, a passenger door auxiliary controller is developed. When the passenger door auxiliary controller receives the driver's intention to open the door, it outputs power to control the relay. After the relay is energized, the passenger door auxiliary controller outputs another door opening signal to the passenger door anti-pinch control box. The passenger door anti-pinch control box outputs a door pump solenoid valve control signal 0.5 seconds later, which passes through the energized relay and reaches the door pump solenoid valve to achieve the purpose of opening the passenger door.

[0030] like Figure 2 and Figure 3 As shown, in this embodiment, the line between the passenger door anti-pinch control box and the door pump solenoid valve is disconnected, and a door pump solenoid valve relay is added.

[0031] As one or more implementation methods, such as Figure 4 As shown, in this embodiment, the power supply of the passenger door auxiliary controller is controlled only by the vehicle's mechanical switches. The GND pin is grounded to ensure normal power supply to the passenger door auxiliary controller. The CANH and CANL pins are connected to the vehicle's CAN bus to read the vehicle speed signal and send the pin status of the passenger door auxiliary controller to the bus for other devices to read. The door rocker power supply pin outputs power to the door pump rocker switch when the vehicle speed is below 3 km / h, supplying power to the rocker switch's door opening signal. This ensures that the rocker switch can send a door opening signal to the passenger door auxiliary controller only when the vehicle speed is below 3 km / h, thus enabling the passenger door auxiliary controller to receive the door opening signal and indicating the passenger's intention to open the door.

[0032] When the passenger door auxiliary controller receives an opening signal from the rocker switch, it outputs a door control relay to control the power supply, closes the door pump solenoid valve relay, and outputs an opening signal to the passenger door anti-pinch control box after 0.5 seconds. The passenger door anti-pinch control box then outputs an opening signal, which passes through the already closed door pump solenoid valve relay to the door pump solenoid valve, thus achieving the purpose of opening the passenger door.

[0033] As one or more implementation methods, the door closing signal of the rocker switch is connected to the door closing input pin of the passenger door auxiliary controller, so that the passenger door auxiliary controller outputs the door control relay control power during the door closing process, closes the door pump solenoid valve relay, and when the anti-pinch function is activated during the door closing process, the door opening signal reaches the door pump solenoid valve from the passenger door anti-pinch control box, so that the passenger door anti-pinch control box opens the passenger door through the anti-pinch function.

[0034] As one or more implementation methods, the valve opening input pin of the passenger door auxiliary controller is connected to the vehicle emergency valve. When the valve opening signal is valid, the passenger door auxiliary controller receives the driver's intention to open the door, outputs the control power of the door control relay, closes the door pump solenoid valve relay, and outputs the door opening signal to the passenger door anti-pinch control box after 0.5 seconds. The passenger door anti-pinch control box then outputs the door opening signal, which passes through the already closed door pump solenoid valve relay to the door pump solenoid valve, reversing the passenger door solenoid valve to open the passenger door. At the same time, the valve opening signal is output to the instrument cluster through the passenger door valve opening output pin, illuminating the valve opening indicator light on the instrument cluster.

[0035] It should be noted that passenger doors are not allowed to open in situations such as when the vehicle speed is high or when there is a swing door in front of or behind the sliding door. Therefore, an additional door opening suppression input pin is added. When this pin is active, the door pump solenoid valve relay output pin and the door opening signal output pin of the passenger door auxiliary controller are not allowed to output, in order to prevent passengers from being thrown out or other accidents from occurring.

[0036] As one or more implementation methods, buses generally have two or more passenger doors. Therefore, the passenger door switch, passenger door emergency valve, door pump solenoid valve relay, and door opening signal are all designed for four passenger doors. An additional master valve opening pin is added. When this pin is active, all door pump solenoid valve relays of the passenger door auxiliary controller output pins, closing all door pump solenoid valve relays. After 0.5 seconds, all door opening signals are output to each passenger door anti-pinch control box. The passenger door anti-pinch control box then outputs a door opening signal for each door, which passes through the already closed door pump solenoid valve relay to the door pump solenoid valve, thus achieving the purpose of opening all passenger doors.

[0037] For the safety of passengers inside the vehicle, even if the passenger door auxiliary controller receives a door opening signal from the rocker switch or a valve opening signal from the emergency valve when there is a vehicle speed signal, it is not allowed to output the door control relay control power and door opening signal, so as to prevent the passenger door from opening while the vehicle is running at high speed.

[0038] When the vehicle is equipped with a remote lock or door button, the passenger door needs to be able to open with only constant power. The power supply of the door button or remote lock is connected in parallel to the door opening signal input pin of the passenger door auxiliary controller. Since the power supply of the passenger door auxiliary controller is connected to the power supply after the mechanical switch, when the door button or remote lock is active, the passenger door auxiliary controller can also output the door control relay control power supply to close the door pump solenoid valve relay. After 0.5 seconds, it outputs the door opening signal to the passenger door anti-pinch control box. The passenger door anti-pinch control box then outputs the door opening signal, which passes through the already closed door pump solenoid valve relay to the door pump solenoid valve, thus achieving the purpose of opening the passenger door. It should be noted that if other components require an opening signal, they will obtain the opening signal from the opening signal terminal of the passenger door auxiliary controller. Even if other components malfunction and output power in reverse, the power can only be output to the opening signal terminal of the passenger door auxiliary controller. Since the door pump solenoid valve relay is only controlled by the passenger door auxiliary controller at this time, it is in the off state and cannot open the passenger door.

[0039] The relay between the passenger door anti-pinch control box and the door pump solenoid valve is controlled by the output of the passenger door auxiliary controller or other control modules. This relay is only controlled by the output of the control module. The input of the module is only a mechanical switch control such as a rocker switch and an external door button. There are no microcontrollers, MOSFETs, controllers, etc., to ensure the purity of the input door opening signal.

[0040] When the driver presses the passenger door switch, the passenger door auxiliary controller receives the door opening signal from the rocker switch, outputs the door control relay control power, closes the door pump solenoid valve relay, and outputs the door opening signal to the passenger door anti-pinch control box after 0.5 seconds. The passenger door anti-pinch control box then outputs the door opening signal, which passes through the already closed door pump solenoid valve relay to the door pump solenoid valve, opening the passenger door.

[0041] This embodiment fundamentally solves the problem of accidental door opening caused by external interference signals through a dual insurance mechanism of "driver intent confirmation + physical circuit isolation". Any signal that has not been confirmed by the driver intent acquisition unit cannot directly drive the door pump. When other components malfunction and reverse current flows into the signal line, the current cannot reach the door pump because the door pump solenoid valve relay is in the open state, thus achieving perfect electrical isolation and dual safety protection, eliminating accidental door opening. The signal source is pure and the intent recognition is accurate.

[0042] This embodiment ensures the absolute purity of the trigger signal for entering the passenger door auxiliary controller by limiting the driver intention acquisition unit to a purely mechanical switch, avoiding false signals caused by electronic component failure or interference, and greatly improving the accuracy of intention recognition.

[0043] This embodiment combines vehicle speed signals and door opening suppression signals to intelligently determine the vehicle status, ensuring that passenger doors can only be opened at a safe low speed or when stationary. This completely eliminates the major safety hazard of passengers being thrown out of the vehicle due to accidental door opening during high-speed travel. It can be added or modified as an additional module to the existing bus passenger door control system. The original control circuit is disconnected and connected to relay contacts, and an auxiliary control box is added. It requires minimal modification to the original vehicle system, has strong compatibility, and is easy to promote and implement.

[0044] Example 2 Based on the bus passenger door control device based on driver intent described in Embodiment 1, Embodiment 2 of the present invention introduces a bus passenger door control method based on driver intent.

[0045] A method for controlling bus passenger doors based on driver intent, comprising: The passenger door auxiliary controller monitors the mechanical switch signals generated by the driver's intention acquisition unit in real time. When a mechanical switch signal is detected, the passenger door auxiliary controller determines whether the current vehicle status meets the preset safe door opening conditions. When the safe door opening conditions are met, the coil of the door pump solenoid valve relay controlled by the passenger door auxiliary controller is energized, the normally open contact closes, and the physical connection line between the passenger door anti-pinch control box and the door pump solenoid valve is connected. After the control relay coil is energized and a preset delay time has elapsed, the passenger door auxiliary controller outputs an opening trigger signal to the passenger door anti-pinch control box. The passenger door anti-pinch control box responds to the door opening trigger signal and outputs a door pump control signal. The output door pump control signal is transmitted to the door pump solenoid valve through the normally open contact of the closed relay, driving the door pump to open the passenger door, thus realizing bus passenger door control based on the driver's intention.

[0046] As one or more implementation methods, the safe door opening conditions include the vehicle speed signal obtained from the vehicle CAN bus being lower than a preset safe vehicle speed threshold, and no other door opening suppression signals being received.

[0047] As one or more implementation methods, the bus passenger door control method based on driver intent also includes door closing control. That is, when the passenger door auxiliary controller receives a door closing signal, it controls the coil of the door pump solenoid valve relay to be energized, so that the normally open contact is closed. During the door closing process, if the passenger door anti-pinch control box outputs a door pump control signal due to the anti-pinch function, the output door pump control signal is transmitted to the door pump solenoid valve through the closed normally open contact of the relay to realize the anti-pinch reverse opening function.
