Lawn mowing vehicle with a control unit for elevating mechanisms
A lawn mowing vehicle ( 1 ) mows a lawn along the travel path of the vehicle. The lawn mowing vehicle ( 1 ) includes: at least one electric reel unit having an electric reel ( 22 ) raised and lowered by an electric cylinder ( 26 a - 26 c ); sensors ( 34 a - 34 c ) for detecting the travel speed of the vehicle; and a control device ( 37 ) for controlling the electric cylinder ( 26 a - 26 c ) according to the result of the detection by the sensors ( 34 a - 34 c ) to thereby control the elevation position of the electric reel ( 22 ).
1. A lawn mowing vehicle having first and second reel units disposed at positions that are different from each other in a frontward/rearward direction thereof with respect to a traveling direction, the lawn mowing vehicle comprising:
a first elevating mechanism that elevates the first reel unit using an electric actuator;
a second elevating mechanism that elevates the second reel unit using an electric actuator;
a speed detection unit that detects a traveling speed of the vehicle; and
a control unit configured to control the first and second elevating mechanisms such that an elevating position of the first reel unit is separated by a calculated travel distance of the vehicle from an elevating position of the second reel unit, the calculated travel distance being calculated based on the traveling speed detected by the speed detection unit, whereby the control unit is configured to change a time from when the first reel unit begins to be elevated to when the second reel unit begins to be elevated depending on the traveling speed detected by the speed detection unit, wherein
the first and second reel units are electric reel units, each of which has a rotating blade driven by a motor and is configured so that a rotational shaft of the rotating blade is set in the leftward/rightward direction that intersects the traveling direction of the vehicle.
2. The lawn mowing vehicle according to claim 1 , further comprising an input unit that inputs an instruction of whether or not to perform automatic elevation control that is control of matching elevating positions of the first and second reel units with each other, wherein
the control unit performs the automatic elevation control when the instruction to perform the automatic elevation control is received from the input unit.
3. The lawn mowing vehicle according to claim 2 , wherein,
when there is no instruction to perform the automatic elevation control, the control unit controls the first and second reel units so as to be individually elevated depending on the instruction input from the input unit.
4. The lawn mowing vehicle according to claim 1 , wherein the calculated travel distance is equal to a distance between the first reel unit and the second reel unit.
5. The lawn mowing vehicle according to claim 1 , wherein the control unit is configured to calculate the calculated travel distance by integrating the traveling speed detected by the speed detection unit from a time when the first reel unit begins to be elevated.
