Control system for cold planer and apparatus and method thereof

A control system comprising:

• a memory configured to store data corresponding to a ventilation mode set by an operator of a milling machine, and to store data corresponding to a conveyor delay amount set by the operator of the milling machine, the ventilation mode being indicative of whether a ventilation system of the milling machine is to turn off as part of a first predetermined sequence of operations to transition operation of the milling machine from a milling mode to a standby mode, and the conveyor delay amount being a time period after which a conveyor of the milling machine stops moving after initiation of the first predetermined sequence of operations to transition operation of the milling machine from the milling mode to the standby mode;
• and
• a controller in communication with the memory, the controller configured to:
• responsive to a first input at a control panel of the milling machine when the milling machine is in the milling mode, control transition of operation of the milling machine from the milling mode to the standby mode according to the first predetermined sequence of operations based on the data from the memory corresponding to the ventilation mode set by the operator and the data from the memory corresponding to the conveyor delay amount set by the operator, and
• responsive to a second input at the control panel of the milling machine when the milling machine is in the standby mode, control transition of operation of the milling machine from the standby mode to the milling mode according to a second predetermined sequence of operations,
• wherein the second predetermined sequence of operations returns each of a plurality of milling machine operational states changed as part of the first predetermined sequence of operations to an operational state at a time of initiating the first predetermined sequence of operations,
• wherein the first predetermined sequence of operations includes the controller controlling a speed of an engine to a low idle state and determining whether the speed of the engine has reached the low idle state prior to determining whether the ventilation system is to turn off as part of the predetermined sequence of operations, and
• wherein the second predetermined sequence of operations includes as first operations, the controller controlling the speed of the engine to a high idle state, from the low idle state, and determining whether the speed of the engine has reached the high idle state prior to performing remaining operations of the second predetermined sequence of operations.

A computer-implemented method for controlling a cold planer, the computer-implemented method comprising:

• receiving, when the cold planer is in a milling mode, a control signal from a first operator control interface to initiate a first predetermined sequence of operations to transition operation of the cold planer from the milling mode to a standby mode;
• and
• controlling the transition of operation of the cold planer from the milling mode to the standby mode according to the first predetermined sequence of operations based on a first input corresponding to a first preset condition of a ventilation system and a second input corresponding to a second preset condition of a conveyor system at a second operator control interface and stored in a memory, in response to the control signal received in the milling mode,
• wherein the first preset condition is whether the ventilation system is set, via the second operator control interface, to an automatic mode or a manual mode, the method further comprising determining whether the ventilation system is set to the automatic mode or the manual mode, and in response to determining that the ventilation system is in the manual mode, not changing an operational state of the ventilation system during the first predetermined sequence of operations, in response to determining that the ventilation system is in the automatic mode, automatically turning off the ventilation system as part of the first predetermined sequence of operations to transition operation of the cold planer from the milling mode to the standby mode,
• wherein the first predetermined sequence of operations includes controlling a speed of an engine of the cold planer to a low idle state and determining whether the speed of the engine of the cold planer has reached the low idle state prior to determining whether the ventilation system is to turn off as part of the first predetermined sequence of operations, and
• wherein a second predetermined sequence of operations includes as first operations, setting the speed of the engine of the cold planer to a high idle state, from the low idle state, and determining whether the speed of the engine of the cold planer has reached the high idle state prior to performing remaining operations of the second predetermined sequence of operations.
