PROBLEM TO BE SOLVED: To provide a riding type lawn mowing vehicle, in which right and left wheels are independently driven by a motor, and which may easily avoid collision to an obstacle target upon rapid pivot to rear side.SOLUTION: A riding type lawn mowing vehicle comprises a drive source, a left wheel and a right wheel, a transmission which may receive driving power from the drive source to independently drive the left wheel and the right wheel with respect to a rotating direction and rotation speed, caster wheels arranged away from the left wheel and the right wheel in a forth and back direction, and a lawn mower, in which rapid pivot may be realized, where one of the left wheel and the right wheel may rotate on rotation center position or the left wheel and the right wheel rotate in an opposite direction, which comprises a first sensor which is arranged on the vehicle and capable of detecting an obstacle target at rear side, and a controlling apparatus decelerating rotation when the obstacle target is detected by the first sensor and rapid pivot to rear side is carried out so that rotation is stopped before collision of the vehicle to the obstacle target.SELECTED DRAWING: Figure 2

    【課題】乗用型芝刈車両において、左右車輪をモータにより独立に走行駆動する構成において、後方への急旋回時に障害対象への衝突を自動で回避しやすい構成を実現することである。【解決手段】乗用型芝刈車両は、駆動源と、左車輪及び右車輪と、駆動源からの動力を受けて左車輪及び右車輪を、回転方向及び回転速度についてそれぞれ独立して駆動可能に構成したトランスミッションと、左車輪及び右車輪に対し前後方向に離れて設けられたキャスタ輪と、芝刈機とを含み、旋回中心位置の回りに、左車輪と右車輪との一方のみが回転するか、または左車輪と右車輪とが逆方向に回転する急旋回が可能であり、車両に配置され、後側にある障害対象を検知可能な第1センサと、第1センサで障害対象が検知され、かつ、後方に急旋回中であるときに旋回を減速させ、障害対象に車両が衝突する前に旋回を停止させる制御装置とを含む。【選択図】図2
