An apparatus for controlling an energy system having at least one energy unit and at least one DC/DC converter, wherein the DC/DC converter is coupled to at least one electrical component, and a power output to the electrical component can be controlled by the DC/DC converter, with the maximum power which can be output to the electrical component being determined by a power limit value of the DC/DC converter. The invention provides that the energy unit and the DC/DC converter and the electrical component are coupled via a limit-value management system which controls the power output such that, when power is demanded from the electrical component above the power limit value of the DC/DC converter, power is output up to the maximum power limit value.

A method for controlling the operating mode of a drive of a vehicle that includes a main drive unit and an auxiliary tractive energy source. The method includes operating the main drive unit, detecting the duration of actuation of an uninterrupted actuation of a brake pedal, and detecting whether the duration of actuation is above a minimum duration by comparing the duration of actuation with a minimum duration. The main drive unit is switched off if it has been detected that the duration of actuation is above the minimum duration. Otherwise, operation of the main drive unit is continued if it has been detected that the duration of actuation is not above the minimum duration. A device for carrying out the method is also described, which includes a timer for detecting the duration of actuation and a comparator for comparing the duration of actuation with a minimum duration.

A system for generating a signal which, in addition to first information representing the rotational speed of a rotating part, contains at least second information. The signal changes over time between a first and a second current level and/or voltage level (high/low). The first information is represented by the time interval between a substantially identical change either between the first to the second level (high/low edge) or a substantially identical change between the second to the first level (low/high edge). On the other hand, the second information is represented by the length of time either of the first or of the second level. No further current levels or voltage levels are used to transmit the additional information, and that the additional information can be evaluated relatively simply. High data integrity can be attained by pulses which are as long as possible.

System for generating a signal to superimpose information

The invention relates to a method for detecting rpm signal errors, in which pulses (t , t , t , t , t and t ) and pulse intervals (t , t , t , t , t ) are generated by poles that generate rpm signals and are disposed on the circumference of a pole wheel. To ascertain a change in speed, pulse intervals (t , t , t , t ) within a first allowable tolerance range are compared in a first step for equality and in a second step for inequality in terms of duration, during one wheel revolution.

Method for recognition of signal errors

The invention is based on a system for changing a signal representing rotational motion in a motor vehicle with first means for generating a first signal representing the rotational motion and a second means for generating at least one second signal representing additional information (direction of rotation, air gap, and/or brake lining wear). In addition, a third means is provided, by means of which the first signal (rotational speed signal) can be changed as a function of the second signal (direction of rotation, air gap, and/or brake lining wear). The essence of the invention is that the first means is designed in such a way that the first signal (rotational speed signal) assumes at least two first current values and/or two first voltage values. In addition, the third means is designed in accordance with the invention in such a way that, to change the first signal (rotational speed signal), at least one of the first current values and/or voltage values can be changed at least for a certain period of time into at least one second current value and/or voltage value as a function of the second signal (direction or rotation, air gap and/or brake lining wear).

A system for superimposing data in which data are represented by a constituted analog signal. The analog signal periodically has two presettable levels (high, low), with the data being represented with the time duration of the analog signal. The presettable levels (high, low) of the analog signal can be realized in this context by two different current or voltage values. Other data are present in the form of a constituted digital signal which represents the data in the form of a digital data word. In order to constitute a superimposed signal, a digital signal is superimposed on the analog signal.

In a connection arrangement between a sensor and connection leads, only a small installation space is required. To this end, the connection arrangement has a signal amplifier, which is electrically contacted by means of bond connections with the sensor and the connection leads. This is achieved by means of connecting elements, which are designed as thin sheet-metal shaped parts and are fixed with tab-shaped end sections in a housing of plastic, in which the signal amplifier is also inserted. The end sections, the signal amplifier, and the bond connections are arranged in a space-saving manner in roughly one plane. The connection arrangement is especially suited for sensors used to measure the speed of motor vehicles.
