Title:
STATE QUANTITY CALCULATION DEVICE, CONTROL DEVICE, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/059544
Kind Code:
A1
Abstract:
Provided is a technique for calculating with high precision a state quantity of a vehicle. An ECU (600) of a vehicle (900) is provided with a ground contact load calculation unit (610), an input quantity calculation unit (620), a first state quantity calculation unit (630), a measurement quantity calculation unit (640), a second state quantity calculation unit (650), and a damper ECU (660). The ECU (600) inputs values calculated on the basis of G-sensor values and the like into a vehicle model, calculates a first state quantity of the vehicle (900), and calculates a second state quantity for the vehicle (900) using a measurement quantity calculated on the basis of a ground contact load and a tire spring constant gain to correct the first state quantity.
