1. A start control device, comprising:
- pinion driving means for driving a pinion pushing device that pushes a pinion into a ring gear coupled with an engine;
motor driving means for driving a motor drive device that rotationally drives a motor coupled with the pinion;
start control means for controlling an operation of the pinion driving means and the motor driving means to start the engine, in response to a start request externally received; and
motor drive torque estimating means for estimating a motor drive torque of the motor,wherein the start control means controls the operation of the pinion driving means, based on the motor drive torque estimated by the motor drive torque estimating means.

Abstract
Provided is a start control device capable of reducing power consumption during the driving operation of a starter motor, to thereby improve fuel efficiency of a vehicle. In the start control device, a motor drive torque estimating part (123) estimates a motor drive torque based on a battery voltage drop amount of a battery (107) that supplies an electric power to a motor (105). A start control part (122) turns off energization of a pinion pushing device (104) by a pinion driving part (120) when the motor drive torque estimated by the motor drive torque estimating part (123) is equal to or larger than a given value.
