Method and device for ascertaining the center-of-gravity height of a vehicle
First Claim
1. A method for ascertaining a center-of-gravity height of a motor vehicle, comprising:
- ascertaining a variable representing a rolling motion of the vehicle about its roll axis oriented in a vehicle longitudinal direction;
ascertaining a variable representing a lateral acceleration of the vehicle; and
ascertaining the center-of-gravity height as a function of the variable representing the rolling motion and the variable representing the lateral acceleration, the center-of-gravity height being ascertained only in predefined driving conditions, the predefined driving conditions being a function of a change in a roll rate per unit of time.

Abstract
A method and the associated device for ascertaining the center-of-gravity height of a motor vehicle, in which
a variable representing the rolling motion of the vehicle about its roll axis oriented in the vehicle longitudinal direction is ascertained,
a variable representing the lateral acceleration of the vehicle is ascertained,
the center-of-gravity height is ascertained from the variable representing the rolling motion and the variable representing the lateral acceleration,
the center-of-gravity height is ascertained only in predefined driving conditions,
the change in the roll rate per unit of time entering into the ascertainment of the predefined driving conditions.
