DETAILED DESCRIPTION OF THE EMBODIMENTS

A clear and complete description will be made to the technical solutions in the present invention below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without any creative effort shall fall within the protection scope of the present invention.
As shown in FIG. 1, a method for controlling a vehicle door and lighting during rail vehicle cleaning, provided by the present invention, includes the following steps.

1. When the vehicle is stationary at a railway yard, a parking-mode switch is operated on an occupied cab to activate a parking mode, a vehicle control unit controls a parking brake valve to operate according to an activation signal of the parking mode, so that the vehicle can be parked safely; meanwhile, the current status of each subsystem of the vehicle is kept and recorded; a driver controller is operated to cancel a driver cab occupancy status, and the vehicle enters the parking mode.

Vehicles are generally parked by service braking. The service braking is effective only when the power is on, while the parking braking uses a spring force to generate a braking action, which can ensure safe parking of a vehicle even if the power is off. The parking-mode switch may be a hardware switch installed on a driver's desk or a soft button on an HMI screen. After the vehicle enters the parking mode, the driver pulls out an occupation key and gets off the vehicle.
2. Some subsystems of the vehicle are automatically controlled or closed according to a set time, and the vehicle enters a sleep mode.
The vehicle is not powered off in the parking mode for maintenance or cleaning of the interior of the vehicle by cleaning personnel, but this causes some loads to remain running and consuming electrical energy. The vehicle control unit automatically controls or closes the operation of some subsystems according to the set time to reduce the power consumption of the vehicle, for example, controlling the brightness of lighting, turning off an air conditioner, turning off fans in the toilet and bar, turning off a cabin display screen of a passenger information system, etc. In this embodiment, the set time is 30 minutes.
3. In the parking mode, professional maintenance personnel or the driver operates an locking-mode switch outside the vehicle with a key to activate a vehicle locking mode, and the vehicle control unit controls the vehicle door to be closed and locked according to an activation signal of the vehicle locking mode, and controls the lighting to be turned off at the same time. When the vehicle locking mode is activated, the vehicle door cannot be opened through an emergency unlocking device, and the vehicle locking mode must be closed with a key before unlocking the vehicle door, thus preventing other persons from entering the vehicle at will by using the emergency unlocking device of the vehicle door when the vehicle is parked, which may cause safety issues, thereby enhancing management of personnel boarding the vehicle, ensuring vehicle safety, and achieving the advantages of safety, reliability, easy implementation, and convenient popularization and application.
4. When cleaning is required, cleaning personnel operates the locking-mode switch outside the vehicle with a key to close the vehicle locking mode. When the vehicle locking mode is closed, the limitation on the emergency unlocking device is released, and the vehicle door can be opened through the emergency unlocking device, so that cleaning personnel can enter the vehicle.
5. The cleaning personnel operates a cleaning-mode switch inside the vehicle with a key to activate a cleaning mode, opening and closing of the vehicle door can be controlled after the cleaning mode is activated, the lighting is controlled to be turned on at the same time, and when the cleaning mode is activated, the vehicle door can be controlled through a local door switch. The cleaning-mode switch is arranged inside the vehicle, next to the vehicle door, which is convenient for the cleaning personnel to operate. The cleaning-mode switch may be the same as the locking-mode switch, and a key corresponding to the cleaning-mode switch may be the same as the key corresponding to the locking-mode switch.
6. After the cleaning is completed, the cleaning personnel operates the cleaning-mode switch inside the vehicle with a key to close the cleaning mode, so that the local door switch is unable to control opening and closing of the vehicle door. The cleaning personnel operates the locking-mode switch outside the vehicle with a key to activate the vehicle locking mode again, the vehicle door is controlled to be closed and locked according to the activation signal of the vehicle locking mode, and the lighting is controlled to be turned off at the same time.
7. The driver operates the locking-mode switch again to close the vehicle locking mode, operates the driver controller to occupy the cab, and operates the parking-mode switch again to end the parking mode.
According to the control method of the present invention, the vehicle door is closed and locked and the lighting is turned off through the activation signal of the vehicle locking mode, and the vehicle door cannot be opened through an emergency unlocking device in the vehicle locking mode; when cleaning is required, the vehicle locking mode is closed, the vehicle door is opened through the emergency unlocking device, and cleaning personnel can enter the vehicle, then opening and closing of the vehicle door can be controlled after the cleaning mode is activated, that is, the opening and closing of the vehicle door can be controlled through a local door switch, and the lighting is turned on at the same time; after the cleaning is completed, the cleaning mode is closed, the vehicle locking mode is activated again, the vehicle door is controlled to be closed and locked through the activation signal of the vehicle locking mode, and the lighting is controlled to be turned off at the same time. The control method of the present invention does not require the control of the vehicle door and the lighting in the cab, so the vehicle door and the lighting can be controlled without the assistance of professional maintenance personnel or the driver, the vehicle maintenance is convenient, and the waste of manpower and material resources is reduced. Besides, the vehicle door cannot be opened through the emergency unlocking device in the vehicle locking mode, thus preventing persons other than professional maintenance personnel, the driver and cleaning personnel from entering the vehicle, thereby enhancing management of personnel boarding the vehicle, reducing potential safety concerns, and ensuring vehicle safety.
