Spray apparatus for a vehicle

A spraying method for a vehicle, comprising:

• providing a processing unit with at least one image of an environment;
• analyzing the at least one image with the processing unit to activate at least one chemical spray unit mounted on a vehicle;
• ejecting a liquid chemical by the at least one chemical spray unit;
• blowing air by at least one air blower mounted on the vehicle into a first downward directed air flow with respect to a fore-aft axis of the vehicle that is parallel to the ground;
• directing air moving as a consequence of movement of the vehicle by at least one diverter mounted on the vehicle into a second downward directed air flow with respect to the fore-aft axis of the vehicle that is parallel to the ground;
• and
• wherein, a chemical spray unit of the at least one chemical spray unit is positioned relative to one or more air blowers of the at least one air blower and is positioned relative to one or more air diverters of the at least one air diverter such that the ejected liquid chemical is at least partially entrained within the first downward directed air flow and is at least partially entrained within the second downward directed air flow.

A non-transitory computer readable medium storing one or more programs, the one or more programs comprising instructions, which when executed by a processor, cause the processor to:

• provide a processing unit with at least one image of an environment from an input unit;
• analyze the at least one image with the processing unit to activate at least one chemical spray unit mounted on a vehicle;
• eject a liquid chemical by the at least one chemical spray unit;
• blow air by at least one air blower mounted on the vehicle into a first downward directed air flow with respect to a fore-aft axis of the vehicle that is parallel to the ground;
• direct air moving as a consequence of movement of the vehicle by at least one diverter mounted on the vehicle into a second downward directed air flow with respect to the fore-aft axis of the vehicle that is parallel to the ground;
• and
• wherein, a chemical spray unit of the at least one chemical spray unit is positioned relative to one or more air blowers of the at least one air blower and is positioned relative to one or more air diverters of the at least one air diverter such that the ejected liquid chemical is at least partially entrained within the first downward directed air flow and is at least partially entrained within the second downward directed air flow.
