Sensor and affiliated storage medium.
Background technology
Resistance is measured for example for battery sensor, the battery sensor is gone to for detection or from battery or electric power storage
Pond passes through electric current.Particularly battery sensor is used to monitor on-vehicle battery in a motor vehicle, and on-vehicle battery is typically electric power storage
Pond.
The voltage declined on measurement resistance is typically measured at herein.The voltage allows the electric current for being inferred to flow through.For this
The resistance value for measuring resistance naturally must be accurately known.
On the one hand the measurement resistance of steady in a long-term and temperature stabilization can be applied for this.It is such to measure resistance but expensive
And it is difficult to handle.Alternatively can be continuously or to determine that time interval carrys out calibration measurement resistance by means of series resistance.
This, which is particularly, or temperature stabilization and can realize series resistance steadily in the long term, and this is held due to the electric current needed for may be significantly smaller
Loading capability and compared to measurement resistance can cost advantages much realize that or series resistance can be by means of steady in a long-term and temperature
Stable current source is spent to calibrate.
It has been proved that these ways cause very accurate result.It has been demonstrated that for it is problematic be improve from
Body current drain and due to bad in the case of high useful electric current/effective current (starting dragging state (Cranking))
Signal to noise ratio and the long time of integration needed.
The content of the invention
Therefore the task of the present invention is that this method is compared to known there is provided a kind of method for calibration measurement resistance
Method is to improve, particularly in itself current drain and/or in terms of the time of integration.In addition, the present invention task be there is provided
Calibrating installation, affiliated battery sensor and affiliated storage medium belonging to a kind of.
This is according to the present invention by method according to claim 1, calibrating installation according to claim 13, according to right
It is required that 14 battery sensor and computer-readable non-volatile memory medium according to claim 15 are realized.Favorably set
Meter scheme can be obtained for example from corresponding dependent claims.The content of claim is included in explanation by clearly quoting
In the content of book.
The present invention relates to a kind of method for calibration measurement resistance, this method has steps of：
- reference current is guided by measuring resistance according to characteristic curve, now

- the voltage declined according to the current strength of reference current and on measurement resistance asks for measuring the resistance value of resistance,
According to present invention provide that, characteristic curve and flow through the useful electric current of measurement resistance and/or with flowing through measurement resistance
The gradient of useful electric current is relevant.
By means of considering characteristic curve, the characteristic curve again relies on useful electric current or its gradient, can be obviously better
In view of present case.Thus, it is possible to reduce current drain in an advantageous manner, for example its method is：In following situation --- wherein
Accurate measurement is all impossible anyway --- lower such adjustment/matching properties curve so that on a small quantity or without reference to electricity
Stream flows through.Can also be for example in the case of small useful electric current or small gradient for small current drain adjustment characteristic song
Line.
Useful electric current is especially understood to such electric current herein, and the electric current flow to ground connection, particularly vehicle bottom from battery
Disk is on the contrary.Gradient can especially be understood to time gradient.
According to an embodiment, characteristic curve includes the current strength of reference current.Therefore can be according to present case
Adjust and optimize current strength.
Preferably, useful electric current is higher, then the current strength of reference current is higher.It particularly can accordingly realize characteristic
Curve.This allows optimization signal to noise ratio and saves electric current in the case of low current intensity.
According to an embodiment, characteristic curve includes keying frequency/gating frequency (Tastfrequenz), with the keying
Frequency application reference current.This is also had confirmed to be favourable for optimizing.
Preferably, the gradient of useful electric current is higher and/or frequency of useful electric current is higher, then keying frequency is higher.This
Have confirmed to be conducive to optimization signal detection and current drain.
Preferably, useful electric current is higher, and keying frequency is higher.This allows the change for quickly detecting resistance value, the electricity
Resistance for example can quickly be changed in the case of higher useful electric current by temperature effect.
According to an embodiment, the reference current with current known intensity is produced by precision current source.
According to an embodiment, determined by the voltage drop measured in the series resistance being connected with measurement resistant series
The current strength of reference current.
Both ways have been proved to be favourable in practice.
If closed using the series resistance of steady in a long-term and/or temperature stabilization, for example by copper-nickel-manganese alloy such as manganese ambrose alloy
The series resistance that gold is constituted, then the resistance value of series resistance can be for example enduringly known.Alternatively, continuously or according to
Interval determines the resistance value of series resistance, such as by means of steady in a long-term and/or temperature stabilization precision current source.
Characteristic curve preferably can be adjusted either continuously or periodically.This allows continuous optimization.
In order to adjust characteristic curve, particularly useful electric current can be either continuously or periodically measured.This allows particularly advantageously
Match with the actual value of useful electric current.
In order to ask for resistance value, it can be advantageous to be averaging on the period.It is possible thereby to eliminate short-term fluctuation.Particularly
Resistance value on period can be averaging at this.
The current strength of useful electric current or reference current is smaller, and the period can be particularly longer.It is strong in small electric current
In the case of degree, the change for having resistance value can be only expected in longer time section, because in the absence of such height of measurement resistance
The temperature change depending on electric current.In the case of small reference current, longer time section can advantageously improve noise
Than.
The present invention is additionally related to a kind of calibrating installation for being used to measure resistance, and the calibrating installation is arranged for, implemented
According to the method for the present invention.All embodiments and modification can be used herein.Illustrated advantage is correspondingly applicable.
Calibrating installation can particularly have memory cell and processor unit, wherein having program stored therein in the memory unit
Code, in configuration processor code, processor unit performs the method according to the present invention.
Particularly characteristic curve can be realized in specific method flow and/or parameter.
The present invention additionally relates to a kind of battery sensor, and the battery sensor has measurement resistance and the school according to the present invention
Standard apparatus, the calibrating installation is connected with measuring a pole of resistance.All embodiments and modification can be used herein.
The present invention is additionally related to a kind of computer-readable non-volatile memory medium, and the storage medium includes program generation
Code, in configuration processor code, computing device is according to method of the invention.Can use herein all embodiments and
Modification.
In general, such as two kinds measures can be taken, to reduce itself current drain and to significantly improve signal to noise ratio.This
Two kinds of measures not only can be used alone but also can apply together.
On the one hand, the size of reference current may rely on useful electric current to be measured, i.e. the useful electric current to be measured is got over
It is high, then reference current is higher.This cause the improvement of signal to noise ratio and in the case of low useful electric current itself current drain drop
It is low.
On the other hand, the keying frequency or dutycycle of calibration signal may rely on the gradient for the useful electric current to be measured
And/or size, that is,
A) useful power frequency is lower, then reference current frequency is lower；
B) useful electric current is smaller, then the keying frequency or dutycycle of reference current are smaller.

Switch 45,55 is alternately connected successively, thus also defines keying frequency.During precision current source 40 is connected with series resistance,
That is, during first switch 45 is closed, calibration electric current is conducted through series resistance 30 from precision current source 40.Calibration electricity
Stream is very accurately known, because precision current source 40 is special temperature stabilization and steady in a long-term.In the calibration electric current
