1. A vehicle start control device for conducting neutral control and hill hold control, wherein, in the neutral control, if predetermined neutral control conditions are satisfied in a drive position, a coupling device provided in a power transmission path between an engine and drive wheels is brought into a slipping state or a released state and thus the power transmission path is kept in a power transfer suppressing state to reduce an engine idling load and, in the hill hold control, if predetermined hill hold control conditions are satisfied on a hill, a brake force is generated in a motor vehicle to hold the motor vehicle against movement on the hill, comprising:

  • a neutral release mode controller that increases a torque transfer capacity of the coupling device in such a manner that the coupling device is engaged more gently in case of releasing the neutral control under the hill hold control than in case of releasing the neutral control when the hill hold control is not executed.
