Abstract
The control apparatus and vehicle of the invention for controlling a broom and blower system attached to the vehicle typically includes several modules (which may be software, hardware, or a combination of these) which interact to process command inputs. Thus, broom state, broom height, and broom direction command modules are all logically connected to a command input module. Similarly, blower state (blower on/off) and direction (blower left/right) modules are also logically connected to the command input module. The method of the invention for operating a broom and a blower includes the steps of receiving a command input, measuring the duration of the command input, and determining whether the command input is a broom state command, a broom height command, a broom direction command, a blower state command, or a blower direction command. If the command is one which requires selection of an intermediate position, then the command is followed as long as the command is entered. If the command is of a relatively short duration, then the command input is latched and held for the length of time required to reach a full-stop position.
