The invention discloses an automatic control system for left and right tracks to travel synchronously better suitable for equipment having relatively high requirement on straightness during traveling. The automatic control system comprises a control handle, a programmable controller PLC, a proportional valve, a left hydraulic motor, a left track traveling mechanism, a left incremental encoder, a right hydraulic motor, a right track traveling mechanism and a right incremental encoder; the control handle is electrically connected with the programmable controller PLC; the programmable controller PLC is electrically connected with the proportional valve; the output end of the proportional valve is divided into two branches, and one branch is orderly connected with the left hydraulic motor and the left track traveling mechanism, while the other branch is orderly connected with the right hydraulic motor and the right track traveling mechanism; the signal output end of the left hydraulic motor is electrically connected with the programmable controller PLC by use of the left incremental encoder; the signal output end of the right hydraulic motor is electrically connected with the programmable controller PLC by use of the right incremental encoder; the proportional valve is electrically connected with the programmable controller PLC by use of two branches of currents simultaneously.
