摘要： A thermal sub-system for a fuel cell system that employs an algorithm using feed-forward control. The algorithm calculates a Reynolds number based on the velocity of the cooling fluid, a diameter of a coolant loop pipe and a kinematic viscosity (temperature) of a cooling fluid. The algorithm also uses a pressure loss number based on the Reynolds number and a position of a by-pass valve. The algorithm also defines a pressure loss value based on the pressure loss number, the density of the cooling fluid and the velocity of the cooling fluid. The algorithm then calculates a delivery head value based on the pressure loss value, the fluid density and a gravitational acceleration. The algorithm then uses the delivery head value and a predetermined set-point value of the volume flow to determine a desired pump speed based on the current operating parameters of the system.

摘要： A method is disclosed for the automatic detection and identification of errors in a balancing machine during operation, in which a rotor provided with an unbalance is rotatably mounted in a vibratory bearing in the balancing machine and is set in rotation by a drive, the rotational frequency of the rotating rotor and the vibrations stimulated by the rotor are measured and measurement signals which comprise the measured values of the rotational frequency and the vibrations are generated and delivered to an evaluation computer. The evaluation calculation is based on mathematical models of the dynamic properties of the balancing machine which describe stimulations of the machine structure due to the unbalance, in particular in the balancing planes, and/or due to the rotor geometry and/or due to the bearing and/or possible damage to the bearing. Features such as vibration characteristics and/or process parameters are calculated by a signal-model-based method from the measurement signals, and discrepancies are established by comparing the calculated features with predetermined normal features of an error-free process.

摘要： A method for steering a motor vehicle in a collision avoidance maneuver ahead of an object in the front or lateral surroundings of the motor vehicle. It is arranged that a linear control method is employed, in which case one controller output signal (δLLM1; . . . ; δLLMN) each is determined in at least two linear controller modules depending on a deviation (e) between an actual position of the motor vehicle and a nominal position that is predetermined due to the avoiding path. The controller output signals (δLLM1; . . . ; δLLMN) are weighted with respectively one weighting factor (Φ1; . . . ; ΦN) that is established depending on the vehicle speed (v), and a steering angle of steerable wheels of the motor vehicle is established based on an arbitration of the weighted controller output signals. Furthermore, a device which is suitable to implement the method is provided.

摘要： A method of compensating inaccuracies in a wheel speed sensor wherein signal-forming elements are arranged on a sensor wheel and wherein a determined angle is allocated to a given number of signal-forming elements to determine a wheel speed, and wherein the wheel speed is determined by evaluating the time during which the wheel rotates around the angle, wherein a correction factor which is included in the determination of the wheel rotational speed is memorized with respect to each element to compensate for variations of the signal-forming elements and/or the positioning of the elements, and the correction factors are updated during the driving operation, wherein updating is performed so that the non-corrected wheel speed measured by the sensor is compared with a reference value of the wheel speed established by means of a calculating model, and the correction factor is updated in dependence of this comparison.

摘要： The invention relates to a process and control circuits for generating defined actuating forces for a brake that is actuated electrically by means of an actuator or electric motor, wherein a first relationship exists between the actuator position and the torque generated by the actuator when the brake is applied and a second relationship exists between the actuator position and the torque generated by the actuator when the brake is released, defining such relationships make it possible to determine the actuating forces occurring during operation without any additional sensors. For this purpose, the present invention proposes that the actuator torques resulting from the first and second relationships be evaluated for determining the efficiency.
