Work vehicle collective switch apparatus and work vehicle equipped with collective switch apparatus
A work vehicle collective switch apparatus includes: a switch operation unit including a plurality of switches; a network side signal output unit that outputs a switch state signal to an in-vehicle network side connected to the collective switch apparatus; a drive signal output unit that outputs a drive signal to a direct-coupled device connected to the collective switch apparatus, and a control unit that outputs a command signal corresponding to switch operation on a basis of switch assignment information that assigns in advance as to whether the drive signal is to be output from the drive signal output unit or the switch state signal is to be output from the network side signal output unit in accordance with switch operation of any of the plurality of switches.
1. A work vehicle collective switch apparatus comprising:
a switch operation unit including a plurality of switches;
a network side signal output unit that outputs a switch state signal to an in-vehicle network side connected to the collective switch apparatus;
a drive signal output unit that outputs a drive signal to a direct-coupled device connected to the collective switch apparatus, and
a control unit that outputs a command signal corresponding to switch operation on a basis of switch assignment information that assigns in advance as to whether the drive signal is to be output from the drive signal output unit or the switch state signal is to be output from the network side signal output unit in accordance with switch operation of any of the plurality of switches.
2. The work vehicle collective switch apparatus according to claim 1 , wherein at least a switch that causes the drive signal output unit to output the drive signal is assigned a function which does not need a vehicle information, and a switch that causes the network side signal output unit to output the switch state signal is assigned a function which needs the vehicle information.
3. The work vehicle collective switch apparatus according to claim 2 , wherein at least a switch that outputs the drive signal from the drive signal output unit is provided for activating a function of a lighting device system of the work vehicle.
4. The work vehicle collective switch apparatus according to claim 2 , wherein at least a switch that outputs the switch state signal to the in-vehicle network side is provided for executing a work capacity change function of the work vehicle.
5. The work vehicle collective switch apparatus according to claim 1 , comprising
a network side signal input unit that inputs a signal from the in-vehicle network side,
wherein, in a case where the signal input via the network side signal input unit is a command signal toward the direct-coupled device, the control unit outputs a drive signal corresponding to the command signal from the drive signal output unit to the direct-coupled device.
6. The work vehicle collective switch apparatus according to claim 5 , comprising
a memory that retains a current operation state for the direct-coupled device corresponding to the drive signal,
wherein, in a case where the signal input via the network side signal input unit is a command signal toward the direct-coupled device, and a drive signal corresponding to the command signal is to be output from the drive signal output unit, the control unit updates the switch state retained in the memory.
7. A work vehicle equipped with a collective switch apparatus comprising:
a vehicle body controller connected to the work vehicle collective switch apparatus according to claim 5 ,
wherein the collective switch apparatus outputs a switch state signal to activate a function of the direct-coupled device to the vehicle body controller in accordance with switch operation of any of the plurality of switches, and
the vehicle body controller outputs a command signal corresponding to the switch state signal to the network side signal input unit based on a determination of the vehicle body controller.
