Abstract
A steering control system for a tracklaying vehicle, which ensures smooth turning performance according to various modes such as ascent travel, descent travel, and travel in a low speed range and which provides improved controllability. According to various operation states such as an ascent travel state, descent travel state, high-load drive state, low engine rotational speed travel state, and high-speed travel state, the clutch/brake modulation characteristic (i.e., static or dynamic characteristic) is varied to select the optimum characteristic.
