Abstract:
1. An engine control method for a vehicle with an idle stop function, comprising: an output limiting step that limits the maximum output torque of an engine to a predetermined limit level when an engine restart condition is satisfied and the engine is started after an idle stop wherein the predetermined limit level of the maximum output torque of the engine in the output limiting step is between 10% and 40% of the maximum output torque of the engine when the opening of a throttle valve is at maximum and wherein the predetermined limit level is within a range of above the minimum output torque needed for driving the engine and under the minimum output torque that generates a shift shock; and a limit removing step that removes the limit of the maximum output torque of the engine by gradually increasing the limited maximum output torque as time passes, the limiting of an output and the removing the limit sequentially performed.
