A time-dependent quantum wave packet method is used to calculate the branching ratio of photodissociation products of the HI molecule in two-color intense few-cycle laser pulses with varying relative phase. It is demonstrated that the relative phase between two intense few-cycle pulses ({omega} and 2{omega}) can be used for controlling the branching ratio of the photodissociation products I({sup 2}P{sub 3/2}) and I({sup 2}P{sub 1/2}) of the HI molecule. The nonadiabatic effect of the crossing potential energy curves on the photodissociation product yields of the HI molecule is also discussed.
