The invention relates to an energy-saving driving control method matched with a mechanical automatic transmission vehicle. The energy-saving driving control method comprises energy-saving slide detection and energy-saving slide control and is characterized in that energy-saving slide detection comprises slide entrance detection and slide exit detection so as to determine whether a vehicle enters or exits an energy-saving slide mode; the energy-saving slide control comprises trial slide control, confirmed slide control and slide exit control, and enables the vehicle to work in a state of breaking or recovering a transmission system on the basis of a judgment result that the vehicle enters or exits the energy-saving slide mode; a manual slide habit of a driver can be imitated, firstly, a clutch is separated to carry out trail sliding for a certain time, and when sliding is confirmed, a neutral position is switched into, so that when a certain energy-saving aim is fulfilled, increase of abrasion on a mechanical mechanism is avoided; moreover, in the process of entering or exiting the slide mode, power flow of the power transmission system can be rapidly and smoothly switched or recovered so as to fulfill the aims of safety and comfort.
