Provided is a technique for simplifying the structure of an idling stop device. The idling stop device 100 includes a deceleration detector 200 which detects deceleration of a vehicle. The idling stop device 100 also includes an estimation part 350 which acquires, based on the deceleration detected by the deceleration detector 200, first deceleration when a vehicle is decelerated to a preset speed or less. Based on the acquired first deceleration, the estimation part 350 estimates a first brake pressure applied to the vehicle when the vehicle is decelerated to the preset speed or less. The idling stop device 100 also includes: an ISC 400 which stops an engine of the vehicle when the first brake pressure estimated by the estimation part 350 is higher than or equal to a preset threshold value; and an ESP 300 which transmits a valve opening/closing control signal to a hydraulic circuit 10 so as to maintain the brake pressure. |
