Abstract: The invention relates to a method and to a device for analyzing a sensor data stream, which characterizes a vehicle environment, with respect to a presence of traffic scenarios. The invention further relates to a method for guiding a vehicle. A similarity measure, which indicates the degree of correspondence between a section of the sensor data stream and at least one template stored in a database, is determined by mapping the section of the sensor data stream to the at least one template, preferably by means of dynamic time normalization. The template thereby characterizes a known traffic scenario. The known traffic scenario is assigned to the section of the sensor data stream, if the similarity measure satisfies a predetermined similarity criterion.

Abstract: A method of determining an insulin bolus to be administered by an insulin delivering device is disclosed. According to the inventive method, glucose measurement data corresponding to glucose level measurement signals detected by a continuous glucose sensor are received. An insulin bolus to be administered by the insulin delivering device is determined based on a formula having expressions indicative of, for example, glucose level derived from the glucose measurement data, carbohydrate-to-insulin ratio (CIR) and an insulin sensitivity factor (ISF). The method can be carried out using a processor of a device such as insulin pen, an insulin pump, a remote control device configured to remotely control an insulin pump or an insulin pen, a continuous glucose meter, a controller of a continuous glucose meter, a blood glucose meter, and a portable electronic device such as a smart phone, smart watch or tablet.

Abstract: An electric motor (2) of a drive train (1) of a hybrid vehicle is controlled by determining the shaft torque (TW) of a current work cycle (n) of an included internal combustion engine (3) and feeding the shaft torque (TW) to a compensation controller (K) which has stored the shaft torque (TW(n?1)) of a preceding work cycle (n?1) of the internal combustion engine, and calculating a compensated shaft torque (Tkomp) from the shaft torque (TW(n)) of the current work cycle (n), the shaft torque (TW(n?1)) of a previous work cycle (n?1), and the shaft torque of a previous work cycle (n?1) shifted by a system delay, which compensated shaft torque (Tkomp) is linked to a target torque (Tsoll) predefined by a higher-level control unit (15) to determine the controlling torque (Tstell) for the electric motor.

Abstract: When arrangements with a repeating working cycle such as, for example, in the case of engine test benches, are being controlled, resonances which have to be damped by the control system are often excited by the test specimen (for example an internal combustion engine) in the working range of the arrangement. The invention proposes for this purpose a control concept in which a modified actual value rist—mod is determined from a current actual value rist—akt of the control system and from a predicted imminent system-delay-free actual value on the basis of the actual value of a previous working cycle, and said modified actual value rist—mod is fed to the control system.

Abstract: A control valve unit for a hydraulic elevator includes two control valves wherein the flow of hydraulic oil from a tank to a lifting cylinder driving an elevator cabin and/or from the lifting cylinder to the tank can be controlled. In case of an upward movement of the elevator cabin, hydraulic oil is conveyed by a pump driven by an electromotor from the tank through the control valve unit to the lifting cylinder. In the case of a downward movement of the elevator cabin, the hydraulic oil flows through the control valve unit to the tank without the pump working. The control of the upward movement and the downward movement of the elevator cabin is achieved by one single pilotable control valve, respectively, that are provided to act as a check valve as well as a proportional valve.

Abstract: A method for controlling a hydraulic elevator whose car can be displaced by a hydraulic drive mechanism by hydraulic oil fed through a cylinder line or evacuated from said hydraulic drive mechanism by a pump that cooperates with a first control valve unit and a second control valve unit, wherein the flow the hydraulic oil is controlled by a measuring device and operation of the elevator can be controlled and regulated by a control apparatus. The load of the elevator car is determined by a load pressure sensor detecting pressure PZ in the cylinder line and is controlled preferably in a constant manner by changing the control of the second control valve unit in such a way that movement of the elevator car can be controlled in a very precise manner. When the elevator car is descending, the dropping pressure PZ in the cylinder line is regulated by changing the first control valve unit in such a way that the descending movement of the elevator-cabin can also be controlled in a very precise manner.

Abstract: The invention pertains to a control valve unit (28) for an hydraulic elevator. It contains two control valves (5, 15) with which the flow of hydraulic oil from a tank to a lifting cylinder driving an elevator cabin and/or from said lifting cylinder to said tank can be controlled. In case of upward movement of said elevator cabin hydraulic oil is conveyed by means of a pump driven by an electromotor, from said tank through said control valve unit (28) to said lifting cylinder, whereas in case of downward movement of said elevator cabin said hydraulic oil flows through said control valve unit (28) to the tank without the pump working. In accordance with the present invention for control of the upward movement and the downward movement of said elevator cabin in said control valve unit (28) one single pilotable control valve (5, 15) respectively is provided for, each of which acts as check valve as well as as proportional valve.

Abstract: The method according to the invention is based on the discovery that the pollutant emissions in the first minutes of operation of an internal combustion engine also depend on the preceding operation and switching off procedure. It is suggested to subject the internal combustion engine and the catalytic converter to a cleaning or a scavenging phase before the standstill of the motor. With this cleaning or scavenging phase the movement of the internal combustion engine is still maintained for a certain time before standstill of the motor either by sparking or by an external drive and at least temporally in at least individual cylinders of the internal combustion engine the supply of fuel is interrupted and exclusively air is delivered. By way of this it is achieved that the remaining pollutants accumulated in the internal combustion engine are supplied to the catalytic converter which is still at the operating temperature and the catalytic converter is enriched with oxygen.

Abstract: A hybrid vehicle and operating method, wherein, given a pending change in the rotational speed of a combustion engine of the hybrid vehicle, provides for a battery, independently of the power to be transmitted to the driving wheels, to be so charged or discharged in a directed manner that the change in rotational speed is effected as swiftly as possible. With regard to fuel consumption, pollutant emission and/or care of the engine, optimal operating points are passed through. On the one hand in the case of a pending increase in power of the combustion engine, it is provided for the battery to be more heavily discharged or less heavily charged according to the initial situation, and in the case of a pending reduction in power, to be more heavily charged or less heavily discharged.
