IDLING STOP DEVICE
First Claim
Patent Images
1. An idling stop device comprising:
- a detection part which detects a deceleration of a vehicle;
an estimation part which acquires, based on the deceleration detected by the detection part, a first deceleration when a vehicle speed is decelerated to a preset speed or less, and estimates a first brake pressure applied to the vehicle when the vehicle is decelerated to the preset speed or less based on the acquired first deceleration;
a brake pressure control part which maintains a brake pressure applied to the vehicle when the first brake pressure estimated by the estimation part is higher than or equal to a preset threshold value; and
an idling stop control part which stops an engine of the vehicle when the first brake pressure estimated by the estimation part is higher than or equal to the preset threshold value

Abstract
A technique for simplifying the structure of an idling stop device. The idling stop device 100 includes a deceleration detector 200 which detects decelerations 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 of 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.
