Description

Technical Field

[0001] This invention belongs to the field of electronic control technology for intelligent new energy vehicles, and particularly relates to a door control system for intelligent new energy vehicles. Background Technology

[0002] Current intelligent new energy vehicles are equipped with numerous electrical devices on their doors, such as window regulators and their control switches, rearview mirror adjustment devices, central locking, door-controlled footlights, speakers, cameras, sensors, etc. These devices are powered by a battery installed within the vehicle body via wiring harnesses. If the vehicle's power supply and its wiring fail during an accident, resulting in a power outage, the entire set of electrical devices on the door will malfunction. For example, windows will not be able to be raised or lowered, and door locks will not open automatically, preventing outsiders from opening the doors to rescue passengers. If a traffic accident results in injuries or entrapment of passengers inside the vehicle, or even a fire, the consequences could be disastrous. Such incidents frequently occur with new energy vehicles. If the door had an independent power system to power the electrical devices, it could be wirelessly charged via the vehicle's power supply under normal circumstances. Even if the vehicle's power supply fails, the door power supply would still have sufficient charge to ensure the door locks open automatically, allowing for timely rescue of passengers inside. Therefore, designing and developing such a control device has significant practical engineering implications. Summary of the Invention

[0003] The purpose of this invention is to provide a system that can provide sufficient power from the vehicle door itself in an emergency when the vehicle's power system fails, so that the windows can automatically lower and the door locks can automatically unlock, creating favorable conditions for rescue. At the same time, when the door battery is low on power, it can also charge itself via a wireless charging device.

[0004] To achieve this technical objective, the present invention adopts the following technical solution:

[0005] A door control system for an intelligent new energy vehicle includes a battery module, a door control ECU (i.e., a door electronic control unit), a wireless charging receiver, a battery status display, a collision sensor, an antenna, a window regulator motor, a door lock actuator, a control switch, and other power electrical components. The battery module is electrically connected to the door control ECU, the wireless charging receiver, and the battery status display. The door control ECU is also electrically connected to the collision sensor, antenna, window regulator motor, door lock actuator, control switch, and other power electrical components. The wireless charging receiver is mounted on the door, near the edge of the side frame. When the door is closed, its position is directly opposite the wireless charging transmitter on the door pillar. The transmitter and receiver together form a complete wireless charger, enabling wireless charging of the battery module. The battery module and the door control ECU are positioned appropriately within the internal cavity of the door body.

[0006] The battery module includes the battery and the battery management system. The battery management system is responsible for controlling and managing the battery's charging, discharging, status monitoring, and safety protection.

[0007] A collision sensor is fixed on the internal bracket of the car door. The collision sensor is placed horizontally. When the car door is closed, the arrow on its outer shell points directly forward of the vehicle, so that it can only detect collisions in the front-to-back direction of the vehicle, but cannot detect lateral impacts when the door is opened and closed.

[0008] The battery status display is an LCD screen located on the outer surface of the door trim panel. It is used to display the charging status, discharging status, remaining charge, and fault information of the battery module.

[0009] The antenna is a Bluetooth transmitting and receiving antenna, which is electrically connected to the Bluetooth unit in the gate control ECU via a wire to achieve wireless communication with the Bluetooth communication unit on the body controller.

[0010] The window lift motor is a DC motor, and its forward and reverse rotation is controlled by the gate control ECU through a wiring harness to realize the raising and lowering of the glass.

[0011] A door lock actuator is an electromagnetic switch, similar to the remote door lock actuators used in existing vehicles. It is controlled by the door control ECU through its forward and reverse current to open and close the door lock.

[0012] Control switches are a general term for various switches, such as window lift switches, rearview mirror adjustment switches, and central locking switches.

[0013] Other power electrical appliances are also a general term for various other power actuators, including rearview mirror adjustment motors, door control footlights, audio equipment, camera devices, etc.

[0014] The beneficial effects of this invention are:

[0015] Under normal circumstances, the battery module provides power to various electrical appliances on the doors. When the battery is low, the body controller charges the battery wirelessly and stops automatically when fully charged. In the event of a collision, the collision sensor generates a collision signal, which is then controlled by the door control ECU to automatically unlock the doors and lower the windows to their lowest position to facilitate rescue. Even if the vehicle's power is cut off after a severe collision, the door control system can still function normally. The door battery status information is directly displayed on the battery status display. At the same time, the door control ECU communicates with the body controller via Bluetooth.

[0019] Please see Figure 1 This application provides a door control system for an intelligent new energy vehicle, including a battery module 1, a door control ECU 2 (i.e., door electronic control unit), a wireless charging receiver 3, a battery status display 4, a collision sensor 5, an antenna 6, a window lifting motor 7, a door lock actuator 8, a control switch 9, and other power electrical appliances 10.

[0020] The battery module 1 is electrically connected to the door control ECU 2, the wireless charging receiver 3, and the battery status display 4; the door control ECU (2) is also electrically connected to the collision sensor 5, the antenna 6, the window lifting motor 7, the door lock actuator 8, the control switch 9, and other power electrical appliances 10.

[0021] The wireless charging receiver 3 is installed on the car door, near the edge of the side frame. When the car door is closed, its position is directly opposite the wireless charging transmitter on the door pillar. The two are combined to form a complete wireless charger to realize the wireless charging function of the battery module 1.

[0022] The battery module 1 and the door control ECU 2 are located in appropriate positions inside the cavity of the vehicle door.

[0023] The battery module 1 includes a battery and a battery management system. The battery management system is responsible for controlling and managing the charging, discharging, status monitoring and safety protection of the battery.

[0024] A collision sensor 5 is fixed on the internal bracket of the car door. In this embodiment, the sensor is a vehicle collision sensor from the car airbag system. It is placed horizontally. When the car door is closed, the arrow on its outer shell points directly to the front of the vehicle, so that it can only detect collisions in the front-rear direction of the vehicle, but cannot detect lateral impacts when the door is opened and closed.

[0025] The battery status display 4 is an LCD display, which is installed on the outer surface of the door interior panel and is used to display the charging status, discharging status, remaining power and fault information of the battery module.

[0026] The antenna 6 is a Bluetooth transmitting and receiving antenna, which is electrically connected to the Bluetooth unit in the gate control ECU2 via a wire to realize wireless communication with the Bluetooth communication unit on the body controller.

[0027] The window lifting motor 7 is a DC motor, similar to the window lifting motors in existing automobiles. Its forward and reverse rotation is controlled by the gate control ECU2 through the wiring harness to realize the raising and lowering of the window glass.

[0028] The door lock actuator 8 is an electromagnetic switch, similar to the remote door lock actuator used in existing vehicles. The door control ECU2 controls the opening and closing of the door lock through its forward and reverse current.

[0029] The control switch 9 is a general term for various switches. In this embodiment, it includes the window lift switch, the rearview mirror adjustment switch, and the central locking switch.

[0030] The term "other power electrical appliances 10" is a general term for various power actuators. In this embodiment, it includes a rearview mirror adjustment motor, door control footlights, audio equipment, and a camera device.

[0031] The following describes the system's working process:

[0032] Under normal vehicle use, battery module 1 provides power to various electrical appliances on the doors. The status information of the door battery can be directly displayed on the battery status display. This information is also communicated in real time with the body controller via the Bluetooth transmitter of the door control ECU. When the battery power is low, the door control ECU sends a charging request signal. After receiving the Bluetooth signal, the body controller controls the wireless charger to charge the battery, and automatically stops charging when fully charged. When the vehicle is involved in a collision of a certain intensity, the collision sensor generates a collision trigger signal to the door control ECU. The door control ECU then controls the door locks to open automatically and controls the windows to lower to the lowest position, creating conditions for rescue. Even in extreme cases where the vehicle's power is cut off after a severe collision, the door control system can still function normally.

[0033] With this device, the problems of car doors locking up after a collision and people being unable to be rescued, as well as the phenomenon of people being burned alive after a collision and fire in a new energy vehicle, can be effectively eliminated.

[0034] The system has a simple structure, is easy to manufacture and use, and is particularly suitable for intelligent new energy vehicles. It is also suitable for promotion and application in other types of vehicles.
