Patent attributes
A center-of-mass height estimation device includes a roll moment calculation unit for calculating roll moment of a sprung portion in a vehicle on the basis of bearing capacities of left and right suspensions provided on the vehicle, a lateral acceleration measurement unit for measuring lateral acceleration, which is acceleration in a width direction of the vehicle, a mass measurement unit for measuring mass of the sprung portion, a transfer function calculation unit for calculating a transfer function of the roll moment with respect to the lateral acceleration, and a center-of-mass height calculation unit for dividing the gain of the transfer function by the mass of the sprung portion to calculate a height from a roll center of the vehicle to a center of mass of the sprung portion.
