step S4131, controlling the supporting frame (200) to move to a headstock, enabling the horizontal brush roller (510) of the top brushing mechanism (500) to be close to the headstock, enabling the foam spraying device (400) to independently spray water at the top and enabling the flushing device (300) to start working, and simultaneously controlling the horizontal brush roller (510) to rotate by a first control motor (540), and enabling the horizontal brush roller (510) to fall down to be attached to a vehicle body;

s4132, controlling the supporting frame (200) to drive the horizontal brush roller (510) to move from the lowest position on one side of the vehicle head to the vehicle tail;

S4133, separating the horizontal brush roller (510) from the vehicle body, starting rotating water throwing, and after the water throwing set time, recovering the horizontal brush roller (510) to the initial position, and stopping the operation of the foam spraying device (400); controlling the supporting frame (200) to retract, controlling the top of the flushing device (300) to spray water during the retracting process, and closing the flushing device (300) when the top of the flushing device is at the initial position.

10. An unattended bus car wash method according to claim 5, wherein: in step S420, the step of controlling the foam spraying device (400), the flushing device (300), and the top brushing mechanism (500) to clean both sides of the bus includes:

step S421, judging whether the foam spraying device (400), the flushing device (300) and the side wall brushing mechanism (600) are in failure, stopping washing the vehicle when the failure exists, and if not, continuing washing the vehicle;

step S422, controlling the supporting frame (200) to move to the headstock, and controlling the vertical brush rollers (610) of the two side wall brushing mechanisms (600) to move to a fitting state; the second control motor (630) drives the vertical brush roller (610) to rotate, and the foam spraying device (400) and the flushing device (300) start to work;

Step S423, the supporting frame (200) drives the vertical brush rollers (610) to move to be attached to the vehicle body, and when the working current of the second control motor (630) reaches a set threshold value, the two vertical brush rollers (610) are separated, and the attached vehicle body advances;

step S4231, when the inclination angle of the vertical brush roller (610) is larger than a set angle, controlling the supporting frame (200) to stop, and simultaneously controlling the vertical brush roller (610) to be far away from the vehicle body until the inclination angle of the vertical brush roller (610) is smaller than the set angle, and controlling the vertical brush roller (610) to be close to the vehicle body again; repeating the step S4231 until the inclination angle of the vertical brush roller (610) is smaller than a set angle, and the working current of the second control motor (630) reaches a set threshold;

step S4232, when the two vertical brush rolls (610) are separated from the car body, the brush rolls stop rotating and return to the initial position, the foam spraying device (400) stops working, the supporting frame (200) is controlled to retract, water is sprayed on the side wall of the flushing device (300) in the retracting process, and the flushing device (300) is closed when the two vertical brush rolls are at the initial position;

in the step S500, the supporting frame (200) is controlled to start from an initial position and move along a vehicle body, and in the moving process, the bright wax spraying device (800) is controlled to spray bright wax on the bus;

When the support frame (200) drives the bright wax spraying device (800) to pass through the complete vehicle body, the bright wax spraying device (800) is closed, and the support frame (200) is controlled to retract to the initial position.
