    • An integrated microprocessor system for safety-critical control systems, comprising at least two microprocessor system modules each comprising at least one processor core, a read/write memory and a memory protection unit, and a read-only memory which is jointly assigned to the processor cores of the microprocessor system modules. Each of the microprocessor system modules executes a main program and a monitoring program which may comprise a plurality of subprograms. If the memory protection unit detects unauthorized operations by one of the programs for accessing a separate address area (A, B) of another program, then the respective memory protection unit assigns a separate address area (A, B) of the read/write memory to the main program and to the monitoring program.

    • In order to adapt a simplified vehicle model to the driving behavior of a real automotive vehicle, it is possible to modify the slip rigidity values assumed to be constant in a linear model. After departure from the linear range of the lateral-force/slip-angle characteristic, a lower value can be assumed for the slip rigidities. However, this will involve the risk that the wheels of the rear axle are already in a slip angle range to which the lower slip rigidity is associated whereas the front wheels are still in the linear range of the lateral-force/slip-angle characteristic. This would impart to the vehicle model an oversteering behavior which should the more so be avoided if such a vehicle model is used for presetting the nominal value. This problem is solved, in the practice of the invention, by suggesting to modify only the slip rigidity values of the front axle while the ones of the rear axle are assumed to be constant.
    • 为了使简化的车辆模型适应于真正的机动车辆的驾驶行为,可以在线性模型中修改假定为恒定的滑移刚度值。 在偏离横向力/滑移角特性的线性范围之后,可以假设滑移刚度较低的值。 然而,这将涉及后轴的车轮已经处于与下滑动刚度相关联的滑移角范围内的风险,而前轮仍处于横向力/滑移角特性的线性范围内。 这将给车辆模型赋予过度转向行为,如果使用这种车辆模型来预设标称值,则应该更加避免。 在本发明的实践中,解决了这个问题,即通过建议在假定后轴的恒定的情况下仅修改前桥的滑动刚度值。

    • Apparatus for improving the driving behavior of a vehicle is provided. The vehicle has front and rear axles, each having a plurality of wheels. Each wheel-has a brake. Sensor are provided for measuring the rotational speed of each wheel, the vehicle yaw rate and the vehicle lateral acceleration. An anti-lock braking system provides first preset pressure values for controlling each brake, to prevent the wheels from locking during braking. A traction slip control system provides second preset pressure values for controlling each brake, to prevent the wheels from slipping during acceleration. A brake effort proportioning system provides third preset pressure values for distributing braking pressure between the wheels of the front axle and the wheels of the rear axle. A yawing moment controller provides fourth preset pressure values used to control each brake during cornering, to avoid application to the vehicle of an unbalanced moment which would cause the vehicle to understeer or oversteer. The antilock braking system, traction slip control system, brake effort proportioning means and yawing moment control system all operate independently of one another. A prioritizing mechanism applies criteria to determine a desired brake pressure that is applied to each wheel, based on the outputs of the antilack braking, traction slip control, brake effort proportioning, and yawing moment control systems.

    • A control circuit for use with an automotive vehicle motion control system such as an anti-lock control (ABS) for an automotive vehicle brake system and/or traction slip control (TCS) includes circuits for processing sensor signals and for generating braking pressure control signals to enable hydraulic valves inserted into pressure fluid conduits of the brake system. The valve control signals are derived from the sensor signals by means of a single-chip microcontroller which processes the data in two successive or time-offset calculating operations performed according to different algorithms. The results of the calculating operations are temporarily stored and compared for coincidence. When the results differ from each other, their deviation is signaled to a monitoring circuit. In addition, the microcontroller is continuously tested by switch-on tests and, during operation, by cycle tests, self-tests, signature analyses and other known methods of error detection.
