Abstract
The present disclosure provides a control method for an engine and a transmission. The control method may include: determining whether a current mode corresponds to a coasting mode; outputting a neutral operation signal to the transmission when the current mode corresponds to the coasting mode; determining whether an operation condition corresponds to a coasting mode release condition based on the signal of each sensor; outputting a D-stage connection signal to the transmission and outputting an engine torque limitation signal to the engine when the operation condition corresponds to the coasting mode release condition; determining whether the operation condition corresponds to a release of the engine torque limitation condition according to an entry of D stage and the signals of the engine RPM and turbine RPM; and outputting a normal operation signal to the engine when the operation condition corresponds to the release of the engine torque limitation condition.
