Title:
スリップ制御装置
Document Type and Number:
Japanese Patent JP7149713
Kind Code:
B2
Abstract:
To provide a slip control device capable of performing stable slip control even if measurement precision of a wheel rotating speed becomes worse at a low speed, and then preventing a vehicle behavior from being disordered.SOLUTION: The present invention is applied to a slip control device 11 which calculates a deviation Δω between a wheel rotating speed ω and an allowable rotating speed ω', or a deviation Δλ in slip rate λ, and also performs feedback control with the deviation Δω using respective variable gainsK, K, and Kfor performing integral compensation, and proportional compensation or/and differential compensation. The slip control device has feedback gain variation parts 14, 14A which decrease one or both of the proportional gain Kand differential gain Kamong the gains used for the feedback control when a vehicle speed V is equal to or lower than a threshold V, and maintain the integral gain Kas it is or decrease it.SELECTED DRAWING: Figure 2
