Title:
VEHICLE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/159559
Kind Code:
A1
Abstract:
Provided is a vehicle control device for controlling a vehicle drive device, capable of enabling slip suppression control to intervene accurately and quickly. This vehicle control device (3) controls a vehicle drive device (4). The vehicle control device (3) is provided with a velocity calculation part (7a), a velocity estimation part, a motion feedback calculation part (7b), and a slip estimation means (9). The vehicle calculation part (7a) computes a velocity of a vehicle in a predetermined direction on the basis of a feature quantity. The velocity estimation part estimates the velocity in the predetermined direction on the basis of a velocity or acceleration detected by a motion detection means (2). The motion feedback calculation part (7b) performs feedback calculation for adding to the feature quantity a value obtained via a proportional gain from a deviation between the calculated velocity computed by the velocity calculation part and the estimated velocity estimated by the velocity estimation part. The slip estimation means (9) compares the calculated velocity with the estimated velocity and estimates that the vehicle is in a slip state in the predetermined direction when the estimated velocity exceeds the calculated velocity.
