摘要:
The present invention relates to a control system for a hybrid system comprising at least one energy store (1) and an energy source (2), the control system using a charge state (Z) in the at least one energy store (1), a nominal operating point (P11) of the energy source (2) and a system power (P1) which is currently to be output to ascertain a storage power (P3) which is to be output or received by the at least one energy store (1) and a source power (P2) which is to be output by the energy source (2) on the basis of at least one optimization criterion. In order to create a particularly flexible control system, the invention provides that at least one charge limit value (P4, P7, P8) and at least one discharge limit value (P5, P9, P10) for the at least one energy store (1) and a power limit value (P12) for the energy source (2) are also used at the same time in order to ascertain the storage power (P3) and the source power (P2), and that the at least one charge limit value (P4, P7, P8), the at least one discharge limit value (P5, P9, P10), the power limit value (P12) and the nominal operating point (P11) can be parameterized via an interface (5) in the control system.

One embodiment of a semiconductor device includes a semiconductor body with a first side and a second side opposite to the first side. The semiconductor device further includes a first contact trench extending into the semiconductor body at the first side. The first contact trench includes a first conductive material electrically coupled to the semiconductor body adjoining the first contact trench. The semiconductor further includes a second contact trench extending into the semiconductor body at the second side. The second contact trench includes a second conductive material electrically coupled to the semiconductor body adjoining the second contact trench.

The arrangement is to allow timely rollover recognition in the event of tipping over an embankment. For this purpose, the arrangement determines a predictive value of the yaw rate of the vehicle after a fictitious impact of the wheels on one longitudinal side of the vehicle against the ground from a yaw rate prevailing prior to the fictitious impact, the momentum of the vehicle in the direction of its vertical axis, and the angular momentum of the center of gravity of the vehicle prior to the fictitious impact. In addition, using the currently measured angle of inclination of the vehicle, it determines a critical yaw rate of the vehicle about its longitudinal axis instantaneously measured by the arrangement, which would be required to cause the vehicle to roll over. A conclusion is drawn about an imminent rollover if the predictive value of the yaw rate exceeds the critical yaw rate.

An undercarriage with a wheel set capable of self-steering independent of the vehicle body is disclosed. The undercarriage contains, in combination with hollow profile wheels in the wheel sets and primary elastic springs in the longitudinal direction, two lever systems which are self-adjusting, independent of each other and are arranged on the longitudinal sides of an undercarriage. The lever systems forcibly couple the axle ends of the wheel sets on the same rail in the longitudinal direction of the undercarriage and are movable only in opposite directions. The levers are further provided with a reversing member tiltably supported at the truck frame, the tilting motions of which are damped by a single damper assigned to each lever system, whereby in a structurally simple, rugged and low-maintenance manner, optimum limitation of the wheel set's freedom of motion relative to the truck frame is achieved in the longitudinal frame direction with respect to radial self-adjustment in track curves and, at the same time, high stability at high speeds is achieved.

In order to perform a simple plausibility check of a rollover decision which is as reliable as possible, an arrangement is provided which signal plausibility of the rollover decision if an acceleration measured in the direction of the vertical axis of the vehicle is either above a preset upper threshold or below a preset lower threshold, or if the acceleration measured in the direction of the vertical axis is between the two thresholds, but an acceleration measured in the direction of the transverse axis of the motor vehicle simultaneously exceeds a threshold which depends on the acceleration measured in the direction of the vertical axis.

The system is intended to have the ability to differentiate between various characteristic driving maneuvers, so that a special triggering algorithm of restraint devices can be initiated for each class of driving maneuvers. This system has an acceleration sensor that measures the acceleration of the vehicle in the direction of its vertical axis. A classifier is provided which, when the measured acceleration is above a threshold of 1 g, decides on a driving maneuver in which the vehicle lifts upward on one side, as when driving on a ramp. If the measured acceleration is between 0 g and 1 g, then the classifier decides on a driving maneuver during which the vehicle tips downward on one side, as when driving on a slope.
摘要:
In order to allow for a timely and reliable recognition of a rollover event of a vehicle, the angular velocities of the vehicle about the yaw axis, the roll axis, and the pitch axis are measured by way of respective rotation rate sensors. A rollover event is signaled as having been detected if an angular velocity exceeds a definable threshold.
