VEHICLE STATE ESTIMATION DEVICE, CONTROLLER, SUSPENSION CONTROLLER, SUSPENSION DEVICE, STEERING CONTROLLER, AND STEERING DEVICE

摘要

To suitably estimate a state of a vehicle.SOLUTION: A vehicle state estimation part 1200 comprises a main calculation part 1210 which performs calculation for a state quantity concerning a vehicle state. An input value to the main calculation part 1210 includes ground load fluctuation of a wheel. The ground load fluctuation of the wheel is calculated with reference to a map with a tire effective radius R, which is calculated by a wheel effective radius calculation part in a tire ground load fluctuation calculation part 1220 as an input and with a ground load with an output.SELECTED DRAWING: Figure 5
