  • Method for estimating the longitudinal inclination of a roadway
    Patent number: 7580784
    Abstract: A method and device for determining a longitudinal inclination variable representing the longitudinal inclination of a roadway, using a sensor “means” present in a motor vehicle, in which a first unbraked driving state of the vehicle and a second driving state of the motor vehicle in which at least one brake is actuated are considered; and as a function thereof the variable representing the longitudinal inclination of the roadway is determined.
    Type: Grant
    Filed: October 26, 2004
    Date of Patent: August 25, 2009
    Assignee: Robert Bosch GmbH
    Inventors: Mario Schmidt, Joerg Grieser
  • Method for determining an estimate of the mass of a motor vehicle
    Patent number: 6980900
    Abstract: A method for determining an estimate of the mass of a motor vehicle for use in controlling the brake system of a motor vehicle, in which a driving force and a force of inertia acting instantaneously on the wheel being determined for all the wheels of the vehicle, and the instantaneous driving forces and inertia forces of all wheels as well as an instantaneous wind resistance of the motor vehicle are added up and divided by the instantaneous longitudinal acceleration of the vehicle to determine the estimate of the mass. In addition, the rolling resistance of the vehicle and/or a braking force acting instantaneously on the wheel is determined for all the wheels and taken into account in the addition.
