Background technology
Disclosed control system such as ABS (Antiblockiersystem-antiblock device) and/or the ESP (Elektronisches that is used for the functional component of automobile
-electronic stability program) regulation accesses the parameter for single automobile modification coding in second computing machine when ROM (read-only memory (ROM)) is not enough.When system quickens, the parameter of modification of activation is copied to the RAM (Random Access Memory-random access memory) of first computing machine from the ROM of second computing machine.Purpose wherein is to utilize existing memory as far as possible best for the reason of cost.
According to standard for example ABS/ESP have only a computing machine.Yet particularly original equipment manufacturer (OEM) (OEM, Original Equipment Manufacturer) wants distinctive additional function is arranged in the controller, so the storage location also has when not enough and has two system for computer.In the ABS/ESP of a current generation, only stipulate a computing machine at present.
Additionally having one according to the current ABS/ESP system of standard, to be used for storage errors, to adjust numerical value and car data and capacity be the E of 1KB to 4KB (kilobytes)
2PROM (EEPROM-can electricly eliminate and the programmable read-only memory (ROM)).
Summary of the invention
But simple in structure, the reliable in function, use that are it according to the advantage of system of the present invention flexibly and cost advantageously make.
Can reach by following measure from these advantages of control system as described in the preamble, promptly at the E of this system according to claim 1
2Store controlled variable in the prom memory, these controlled variable are identified for the parameter (parametrisieren) of the system of different automobile modification.
A fundamental point of this control system is to utilize already present E in system usually
2Prom memory.Therefore do not need to be provided with additional parts for the parameter of storing the modification coding.These additional parts have similarly increased its complexity, need the space, have also improved the manufacturing cost of circuit.New-type utilization to memory device can realize on disclosed failure-free circuit that these circuit needn't carry out the change of essence for this reason.
If many parameter group must be stored in the controller according to customer requirements, but the resource of ROM is not enough, particularly produces described advantage in the time of therefore must using bigger computing machine.If second computing machine only is used to access the parameter that modification is encoded in this case, then this relates to the huge extra cost that is used for controller.When because will to access the modification coding parameter must also be like this when second computing machine that has been provided with a more large-scale computer generation too.
But system according to the present invention on the contrary allows better scaling property (Skalierbarkeit) under the conditions of demand of the storage location of limit.This uses particularly, and cost provides the desired storage location of user storage level to become possibility best.Also can become sequence ground to change parameter in addition continuously and need not computing machine itself is changed, this also makes at ABS and/or the ESP ROM computing machine that use cost is favourable more easily in the works.
In claim 2 to 4, the preferred improvement project according to system of the present invention is illustrated.
In one of system favourable form of implementation, stipulate E in view of the above
2Prom memory has the capacity that surpasses 32 kilobytes, particularly 64 kilobytes, 128 kilobytes or 256 kilobytes.The extra cost that is used for this is lower than the extra cost of second computing machine significantly, and also is lower than the additional expense of more large-scale computing machine.Because sort memory and less E
2PROM-memory device lead-in wire is compatible (pinkompatibel), therefore needn't change computing machine.
Except obviously more favourable cost, also have following advantage, can change E at any time
2Parameter in the prom memory.Therefore the very big alerting ability that system just occurred.For example need not to change controller software and just can be in " continuous variation " (a Running Change) mend modification into other with continuous group form, change parameter with continuous group form, replace the modification that no longer needs with new modification, and can also continue to support old automobile even so.Can also provide special modification in addition, for example automobile of Jia Guing or special-purpose motion version.
Wherein, guarantee a kind of special reliability of this system by following measure, promptly the RAM memory device has a wrong identification and correcting mechanism.In the time can not carrying out periodic parameter update (Parameter-Refresh) with identical speed, for example at this moment the parameter update that is carried out when parameter calls out to second computing machine can require to use the RAM memory device with ECC (Error CorrectionCode-error-correcting code)/EDC (Error Detection Code-error detector sign indicating number) especially.
Can be preferably used as ABS-and/or ESP system according to system of the present invention because just in time used usually there a kind of according to the present invention available E
2Prom memory.
Above-mentioned advantage also can obtain by a kind of method that is used for the functional component of Control of Automobile.This method comprises an E who controlled variable is stored into the operating data that is used for automobile
2(these parameters are determined the parameter of different automobile modification) in the prom memory, the parameter of the automobile modification that correspondence is actual is from E
2Be written into the RAM memory device of computer unit in the prom memory, and according to the step of these parameters by the functional component of this computer unit Control of Automobile.
Wherein, the method according to this invention fundamental point is its realization property that is easy to.This realization is only required E
2Prom memory carries out suitable management.In addition, disclosed failure-free circuit is not carried out the change of essence because this method requires, so but abnormal cost advantageously realize.
By using E
2Another advantage has appearred in prom memory, promptly in order at magnetic tape trailer (Bandende) ROM (Flashen) original equipment manufacturer (OEM) of programming not to be needed the Infrastructure that provides special.With at magnetic tape trailer the automobile specified parameter group is write selection among the ROM and compares all parameters that are used for all the automobile modification that can expect and all be included in E
2Among the PROM.
In manufacturer, simplified logistics on the contrary, because must be provided for E according to control system of the present invention
2The single parameter group of PROM, rather than whole software (
).The computing machine modification that also can abandon adding as requested.
Therefore, the parameter with the modification coding when quickening in system is not to be loaded into the RAM of first computing machine from second computing machine, but from E
2Take out among the PROM.Other mechanism remains unchanged.Yet can require to use RAM main memory, because periodic parameter update can not carry out with identical speed as when parameter is called out to second computing machine with ECC/EDC.
Some preferred improvement projects to the method according to this invention in claim 6 to 8 are illustrated.
In a favourable projecting point of the present invention, be defined in method run duration controlled variable in view of the above and be replaceable, change and/or remove.Advantage mentioned above so just appears.Need not to change controller software according to these advantages and for example in a kind of " changing continuously " (Ranning Change), replenish into other modification with becoming sequence continuously, become sequence ground to change parameter continuously, with the modification that new modification replacement no longer needs, can also support old automobile even so.In addition, also special modification be can provide, the automobile or the special-purpose motion version of reinforcing for example are used to.
In this case advantageously, remove the controlled variable that no longer needs of automobile modification, perhaps replaced with new parameter.Can in the scope of the modification of whole automobile, handle by this measure, for example remove the automotive type that no longer is supported, and receive other controlled variable.
The timing requirement of OEM when starting in system in order to satisfy is preferably just set up a kind of network service at the first loading duration of controlled variable between the computer unit of automobile and other functional component.
