  • Publication number: 20150291155
    Abstract: A method for improvement of safety when driving a vehicle includes the steps to: continuously (s410) establish a measure of instability relating to the vehicle; continuously provide (s420) the measure of instability within a communications network internal to the vehicle (L230, L240), to which network at least one vehicle braking function's control device (240a; 240b; 240c; 240d) is connected; and continuously establish the measure of instability based on a difference between an expected propulsion and an actual propulsion. Also, a computer program product with program code (P) for a computer (200; 210) to implement the method. Also, a device (298, 299) for improving safety when driving a vehicle and a motor vehicle (100) equipped with such a device.

  • Patent number: 7286919
    Abstract: A method and algorithm for semi-active suspension damper control is described. The algorithm controls the damper setting to limit vehicle body movement in terms of body modal velocities of heave, roll and pitch. The main input, body movement, is measured with accelerometers. The control output comprises a request in percent of damper control range. Vehicle speed-dependent minimum and maximum limits are applied. The method includes monitoring vehicle speed and a modal sensing system. A common damping rate for the dampers is determined based upon parameters for speed, heave, pitch, and roll. Each damper is controlled based upon the common damping rate adjusted based upon a location of each of the controllable suspension dampers. The output comprises a single signal, translated to a front and rear setting. The purpose is to always have a balanced setting of the four dampers.

  • Publication number: 20070174481
    Abstract: A method of rapidly sending large volumes of information to one or more personal computers from a database containing information. A personal computer is connected to the database via a first communication network, such as the Internet, to a server connected with the database to allow a user to request information. A second communication network, such as a DAB radio network, transmits requested information from the server at high speed to a receiver unit in the possession of the user. A proxy server between the personal computer and the server selectively either forwards collected information for transmission to the receiver unit via the digital radio network, to allow information received in the receiver unit to be transferred to the personal computer, or, alternatively, to allow the direct transfer of information between the server and the personal computer.
