Abstract: A method for increasing the reliability of sensor systems for determining the position of flying objects. Since the position determination is very decisive for the execution of planned missions, it is especially important to increase the reliability of such systems. The star sensors of the star systems are preferably structured identically and connected to each other by a bidirectional bus system. Due to the presence of several identical modules in the sensor system, there is an inner redundancy that can be utilized via the bus system. The bus system allows the transmission of signals of different data processing levels, so that the transmission of the data of the data processing levels can be adapted to modules that may have failed.

Abstract: A method of controlling a battery electric vehicle includes displaying an energy consumption parameter to a vehicle operator.

Abstract: In a control apparatus, a filter processor filters target torque for a rotary electric machine to suppress a vibrational frequency component of a drivetrain using a filter having a frequency transfer characteristic. A controller performs drive control of the rotary electric machine according to the filtered target torque. A parameter calculator calculates, according to a running condition of the vehicle, a parameter associated with a request value for responsivity of output torque of the rotary electric machine with respect to the target torque. A variable setter variably sets the frequency transfer characteristic of the filter to decrease a degree of attenuation of the vibrational frequency component with an increase of the request value for responsivity of the actual output torque. A limiter limits a rate of change of the degree of attenuation to suppress vibrations of the drivetrain.
