Description

The invention relates to an electronic security component, having a supply input and a component output, which are electrically connected to one another via an isolating switch, and having at least two measuring devices. The invention also relates to a safety system, having at least one electronic safety component and a triggering logic, which is connected to the measuring devices and the disconnector in terms of signals and which is set up to evaluate the measured values determined by the measuring devices and to control the disconnector based on the result of the evaluation. The invention also relates to a vehicle that has at least one such security system. The invention can be applied particularly advantageously to vehicles, in particular when installed in an on-board power supply system of a vehicle.

In order to prevent system failures in a vehicle due to undervoltages and to protect against thermal events such as arcing, etc., components of the vehicle such as at least one electrical load, at least one electrical energy source (e.g. a battery, a supercapacitor or a converter), at least one Power distributors, etc. partially protected by electronic fuses (also known as "E-Fuses" or "Smart Fuses"). As in 7 shown, a conventional electronic fuse 101 has an electronic circuit breaker 102 (eg, a bipolar transistor, a MOSFET, etc.) that is installed in series between a supply input 103 and a component output 104 . The component output 104 is intended in particular to be electrically connected to the at least one vehicle component to be protected.

In the current path between the supply input 103 and the component output 104 there is also a voltage measuring device 105H and 105L on each side of the isolating switch 102 . The two voltage measuring devices 105H, 105L are connected to ground GND via a common node. Also located in the current path between the supply input 103 and the component output 104 is a current measuring device 106H for measuring the electrical current passed through the current path. The voltage measuring devices 105H, 105L and the current measuring device 106H are connected in terms of data technology to a triggering logic 107, which can also selectively switch the isolating switch 102 to be conductive or blocked by means of a corresponding control. The triggering logic 107 can detect voltage dips in the voltage measuring devices 105H, 105L and current dips in the current measuring device 106H and then block or open the isolating switch 102 by means of a corresponding control. In addition, the triggering logic 107 can monitor a voltage difference between the two voltage measuring devices 105H and 105L and thus detect a defective circuit breaker 102 . If, for example, the voltage difference is high although the isolating switch 102 is switched on, or if, for example, the voltage difference is low although the isolating switch 102 is switched off, a fault in the isolating switch 102 can be assumed. In particular, the tripping logic 107 can differentiate between different faults such as short circuits, creeping short circuits, wrong polarity, undervoltage, etc. Since the isolating switch 102, due to its property as an electronic switch, is also set up to be reversibly commanded to be selectively blocking or conducting or opened or closed, the isolating switch 102 can be selectively switched when a fault is detected by the tripping logic.

These advantages of the electronic fuse 101 are offset by the fact that it is an electronic component and is therefore subject to a higher probability of failure or error than, for example, a mechanical fuse (e.g. a fuse). Possible errors can occur, for example, in the measurement (too high, too low, measurement failure, etc.) or in the separating element / switch (accidental or incorrect opening, closing, etc.). In such a case, the rest of the vehicle electrical system is not protected, especially in the event of short circuits, impermissible currents and/or heating in the current path of the component(s), and the overall system safety (e.g. including functional availability, functional safety and passenger safety) is endangered.

It is the object of the present invention to at least partially overcome the disadvantages of the prior art and in particular to improve the protection of electrical components protected by electronic fuses and higher-level systems, in particular an on-board supply network, in vehicles in a cost-effective manner.

This object is solved according to the features of the independent claims. Preferred embodiments can be found in particular in the dependent claims.

• - einen Versorgungseingang und einen Komponentenausgang,
• - die über mindestens zwei elektronische Trennschalter miteinander elektrisch verbunden sind, und
• - mindestens zwei Messeinrichtungen.

The task is solved by an electronic component (“fuse component”), having:

• - a supply input and a component output,
• - which are electrically connected to one another via at least two electronic circuit breakers, and
• - at least two measuring devices.

This component has the advantage that there are a number of isolating switches and a number of measuring devices. This redundancy can reduce susceptibility to errors and consequently increase system, functional and component reliability. Especially due to the redundancy of the measuring devices, the circuit breakers can be tripped in a highly reliable manner and measurements can be checked for plausibility in parallel, e.g. in the event of drifting away or an inconsistency ("measurement validation"). The integration of multiple disconnectors and measuring devices in a single component can also be implemented particularly cost-effectively. The triggering can take place via one or two independent triggering logics. The electronic security component can be used particularly advantageously when high-availability vehicle components are to be secured.

The fact that the security component is an electronic security component can include that at least the isolating switches and possibly also at least one of the measuring devices are designed as semiconductor elements.

The fuse assembly has two electrical terminals for inserting the fuse assembly into a power line, referred to without limitation as "supply input" and "component output." In particular, the fuse component can be designed to conduct current through it with particularly low losses or practically no losses when current flows from the supply input to the component output. In one development, the fuse component is provided as a high-side component, in which the at least one consumer to be protected is connected to the component output (“behind” the fuse component) in the voltage or current direction.

The isolating switch is designed to interrupt an electrical line (e.g. a busbar) in which it is inserted by means of suitable switching or activation from the outside. The fact that the circuit breaker is an electronic circuit breaker includes, in particular, that it has at least one semiconductor switch, e.g. a MOSFET. As a result, it is also reversible, i.e. it can be selectively controlled to block and/or conduct (a transistor, e.g. by applying a corresponding blocking voltage to the control connection), whereby its switching state can be changed as often as desired.

In this case, the safety component is in particular a component that has the function of protecting at least one functional component connected thereto, in particular downstream in the current direction. The fact that the security component is a component includes, in particular, that it is an inseparable object (without being destroyed). In particular, the component can have a housing that encloses the electronic circuit breakers and the measuring devices. In particular, the electronic circuit breakers can be formed on a common semiconductor substrate, in particular a silicon substrate (“chip”). In one development, at least some of the measuring devices can also be formed on the semiconductor substrate. The semiconductor component can be embedded in the housing, in particular in such a way that only electrical connections such as the supply input, the load outlet and signal connections of the measuring devices are brought out. The housing can be an injection molded part.

In one development, every possible current path between the supply input and the component output has at least one isolating switch. In particular, there is no current path between the supply input and the component output past the isolating switches.

The at least two electronic isolating switches can include two, three, four or even more electronic isolating switches, which can be electrically connected to one another in basically any topology or arrangement.

A measuring device is understood to mean, in particular, a device for quantitatively measuring at least one physical variable (e.g. current, voltage, temperature, etc.), which outputs a value of this physical variable as the result of the measurement (e.g. x ampere, y volt, z °C, etc.).

The at least two measuring devices can include two or more measuring devices. The at least two measuring devices can include measuring devices “of the same type” (ie measuring devices that determine the same physical variable) and/or measuring devices of “different type” (ie measuring devices that determine a different physical variable). The at least two measuring devices can thus include, for example, exactly one voltage measuring device, exactly one current measuring device and/or exactly one temperature measuring device. The fact that a measurement validation can also be achieved by comparing different physical quantities can be used here can be. In particular, measuring devices of the same type can be identically constructed measuring devices. In a further development, the measuring devices can be in the form of semiconductors.

In one configuration, the at least two isolating switches are exactly two isolating switches which are arranged electrically in series with one another between the supply input and the component output. This achieves the advantage that the electronic security component blocks particularly sensitively and reliably, since the connection between the supply input and the component output is already interrupted by the isolating switch that blocks first. If disconnection by one of the two switches is not possible, the current flow can be interrupted by the other switch. This can also be referred to as "safe disconnect". In this configuration, the supply input, the two isolating switches and the component output are electrically connected in series.

In one configuration, the at least two isolating switches are exactly two isolating switches which are arranged electrically parallel to one another between the supply input and the component output. In this way, the advantage is achieved that if one of the isolating switches fails in such a way that it is permanently blocked, the current flow through the other switch can be maintained. This can also be referred to as "secure connection".

In one configuration, the at least two isolating switches are four isolating switches which are arranged in two electrically parallel branches each having two isolating switches electrically connected in series with one another. In this way, the advantage is achieved that if one of the circuit breakers in one of the branches fails, redundancy is still guaranteed by the other branch. In this way, safe disconnection and safe connection are advantageously combined.

The circuits above for the circuit breakers can basically be expanded as desired, e.g. to more than two circuit breakers connected in series, to more than two parallel branches, to a combined series and parallel circuit, etc.

In one configuration, the at least two measuring devices include at least one group each with at least two measuring devices of the same type. This facilitates a measurement validation on the measuring devices of the same type and, for example, also a detection of creeping errors.

In one configuration, the at least one group with at least two measuring devices includes or has at least one group with at least two voltage measuring devices. In other words, the electronic security component has at least two voltage measuring devices. This achieves the advantage that the voltage measurements are designed to be redundant, which in turn means that an inaccurate or faulty voltage measuring device can be detected. For example, determined, in particular measured, voltage levels and/or voltage curves can be compared with one another.

In a further development, the isolating switches are arranged electrically in series with and between the voltage measuring devices. In this way, the advantage is achieved that the voltages upstream and downstream of the isolating switches can be measured, making it particularly easy to diagnose faults and failures in the isolating switches. In particular, the supply input, at least one voltage measuring device, the isolating switch, at least one voltage measuring device and the component output are electrically connected in series in this order. In another development, at least one voltage measuring device can be arranged electrically between two isolators or groups of isolators, which can further simplify fault diagnosis of the isolators.

In one embodiment, the voltage measuring devices are connected to ground separately or independently of one another, e.g. are connected to a body or ground line of a vehicle. This achieves the advantage that, in contrast to a connection to ground via a node common to the voltage measuring devices, a measurement deviation of one of the voltage measuring devices due to faulty or unreliable contact with ground can be identified. A voltage offset of the different connection points is typically negligible, e.g. when connecting to a body due to the small distance and the low body resistance.

In one configuration, the at least one group with at least two measuring devices includes or has at least one group with at least two current measuring devices. In other words, the electronic security component has at least two current measuring devices. This achieves the advantage that the current measurements are designed redundantly, as a result of which an inaccurate or faulty current measuring device can in turn be recognized by measurement validation.

In a further development, the isolating switches are arranged electrically in series with and between the current measuring devices. In this way, the advantage is achieved that the current through the electronic safety component can be measured several times and an inaccurate or faulty current measuring device can thus be identified particularly easily. In particular, the supply input, at least one current measuring device, the isolating switch, at least one current measuring device and the component output are electrically connected in series in this order. In another development, a respective current measuring device can be arranged electrically in one, several or all parallel current branches or paths, which can simplify fault diagnosis of the isolating switch even further.

In one configuration, the at least one measuring device has at least two current measuring devices which measure a current intensity of currents flowing in opposite directions, i.e. one of these at least two current measuring devices measures a current intensity of a current in a first direction and the other of these at least two current measuring devices measures a current intensity of a current in a second direction opposite to the first direction. This has the advantage that feedback currents can be easily identified.

In one configuration, the at least one group with at least two measuring devices includes or has at least one group with at least two temperature measuring devices. In other words, the electronic security component has at least two temperature measuring devices. This has the advantage that the temperature measurements are designed redundantly, which in turn makes it possible to identify an inaccurate or faulty temperature measuring device (e.g. a temperature sensor).

The object is also achieved by a security system having at least one electronic security component as described above and at least one triggering logic, which is connected to the measuring devices and the disconnectors in terms of data or signals and which is set up to determine, e.g. measured, the measuring devices Evaluate measured values and control the circuit breakers based on the result of the evaluation. The security system can be designed analogously to the electronic security component and has the same advantages. In particular, the tripping logic can be used to achieve a highly reliable tripping of the circuit breakers by plausibility checks of measurements or measured values from measuring devices of the same type relative to each other and/or by plausibility checks of measurements or measured values from measuring devices of different types relative to each other.

A tripping logic can be understood in particular as a data processing device which processes measured values determined or determined by means of the measuring devices for evaluation and, based on the result of the evaluation, decides on the switching state (conducting / blocking or open / closed) of the disconnectors and the disconnectors for taking of the desired switching state.

For this purpose, the tripping logic is connected to the specific measuring devices and circuit breakers in terms of data and signals. It can therefore receive measured values from these measuring devices in analog or digital form and output control signals to the electronic fuse component or the specific isolating switch, e.g. set suitable control voltages for the control connections of the isolating switch, which causes them to be switched (i.e., retain their previous switching state or change their change switching status).

In one development, the triggering logic is a component that is different from the electronic security component, in particular a vehicle component, that is to say an entity “external to the security component”. This instance can be a stand-alone component or can be functionally integrated with a component used for other purposes such as an energy management system, an on-board computer, and so on.

It is a development that the triggering logic is integrated into the electronic security component. In this way, the advantage of autonomous monitoring and triggering is achieved.

In a further development, triggering logic (external to the fuse component) is connected to a plurality of electronic security components. It can then advantageously monitor and control a number of electronic security components at the same time.

In one configuration, the at least one triggering logic has exactly one (“central”) triggering logic that is set up to evaluate the measured values determined by all measuring devices and to activate all disconnectors based on the result of the evaluation. In this way, the advantage is achieved that the triggering logic for diagnosis and/or decision-making about the switching positions of the isolating switches takes into account the measured values of all measuring devices. In the case of correlations, faulty assembly components can advantageously be identified particularly reliably in this way (an error state can possibly even be predicted), and it is possible to react to such events in a particularly reliable and intelligent manner.

In one configuration, the at least one triggering logic has a plurality of triggering logics which are independent of one another or which act independently and which are set up to evaluate the measured values determined by a respective part of the measuring devices of at least one group and to open a respective part of the circuit breaker based on the result of the control evaluation. This achieves the advantage that the triggering logics are also designed redundantly, so that in the event of a fault or failure of one of the triggering logics, at least the isolating switches that can be switched by the (at least one) other triggering logic can be switched or activated. In particular, the multiple triggering logics are constructed in the same way.

In a further development, each triggering logic is assigned the same number and type of measuring devices, e.g. a voltage measuring device, a current measuring device and/or a temperature measuring device and/or the same number and type of isolating switches. This facilitates a similarly redundant mode of operation.

In one development, the at least one triggering logic has exactly two triggering logics. These can, for example, each control one, two or even more circuit breakers.

It is an advantageous configuration, particularly in the event that there are four circuit breakers, which are arranged in two electrically parallel branches, each with two circuit breakers electrically connected to one another in series, that the at least one triggering logic has two triggering logics that are independent of one another and are set up to to control both circuit breakers of a respective branch.

The object is also achieved by a vehicle having at least one electronic security component and/or at least one security system as described above. The vehicle can be designed analogously to the electronic security component and/or the security system and has the same advantages. At least one security component and/or at least one security system can be part(s) of an on-board power supply system of the vehicle. In particular, the at least one electronic security component can be integrated into an electrical vehicle component such as a consumer, a control device, a power distributor, an electrical energy source, etc.

The vehicle may be an internal combustion engine vehicle, a hybrid vehicle, or an all-electric vehicle.

The vehicle may be a land-based vehicle (such as a car, truck, motorcycle, bus, etc.), a watercraft, or an aircraft (such as an airplane, helicopter, etc.).

The vehicle is in particular a partially or fully autonomous vehicle for which the safety component and the safety system can be particularly useful due to the increased importance of fail-safety of electrical components.

The object is also achieved by a method for controlling isolators of an electronic security component as described above, which is a component of a security system as described above, in which the measured values determined by the measuring devices are evaluated by means of the at least one tripping logic and the isolators by means of the at least a triggering logic based on the result of the evaluation can be optionally switched on or off. The method can be designed analogously to the electronic security component, the security system and/or the vehicle and has the same advantages.
