Abstract: A method of controlling drivability of a vehicle detects an overall load acting on the vehicle. A mass of the vehicle or an estimate thereof is obtained. A controller determines whether the vehicle is negotiating a curve during a driving situation. If the vehicle is negotiating a curve during the driving situation, the controller determines whether the vehicle has a tendency to oversteer or to understeer. The load acting on the vehicle is dynamically changed or a suspension stiffness of the vehicle is dynamically adjusted to reduce the tendency of the vehicle to oversteer or to understeer.

Abstract: Intermodule testing in a computer system including a plurality of modules interconnected via a system bus is performed by means of a serial test bus which is incorporated into the computer system for testing components, for example integrated circuits, used to construct the modules of the computer system. Intermodule test data is maintained in memory on each of the modules and is accessible through operations of the serial test bus. Intermodule test data is retrieved by the serial test bus and used to set up the modules so that one module drives the system bus with test signals defined by test vectors included within the intermodule test data. The remaining modules are set up to receive the test signals. Tables are developed in accordance with the intermodule test data to define which test signals drive which system bus leads and also which receiving modules receive the test signals.

Abstract: Nonvolatile memory is provided on each module of a computer system including one or more modules with each module including a plurality of components including JTAG technology. A test bus operable in accordance with the 1149.1 standard is included in the computer system and is arranged to access the nonvolatile memory. Boundary scan information for the components on a module and also additional information, preferably fully describing all JTAG related characteristics and operations, is stored in the nonvolatile memory. A JTAG bus system is then able to access the module memory and obtain all information required to fully implement JTAG operations for the module.
