Abstract
Description
- This invention relates to a vehicle braking system using stored vehicle parameters for electronic control of brake forces and relates more especially but not exclusively to road trailer vehicle compressed air operable brakes which are signalled from a tractor vehicle.
- In European and other countries there are a large number of small engineering companies building road trailer vehicles designed for use with various tractors employing compressed air operable brakes. Such trailer builders tend to specialise in specific vehicle types but to meet statutory braking requirements it is a common feature that trailers are provided with means which controls the braking force signalled from a towing tractor, and uses a proportional load sensing valve for adjusting brake pressure or in the case of electronic load sensing has an electronic control unit (ECU). In the case of a system which a mechanical load sensing pressure proportioning valve, if the valve needs to be replaced, a replacement valve can be readily set up using parameters supplied to the user with the trailer, by the builder, to define pressure producing the onset of braking (i.e. inshot), tare weight braking and full load braking.
- However in the case of electronic control by an ECU, possibly also including anti-lock control specific trailer parameters are initially installed into a configuration data memory of the ECU by a trailer builder using specialised equipment. If the ECU is subsequently required to be replaced due to failure or damage there is a problem in that the vehicle operator is normally unlikely to possess or have ready access to such specialised or suitable peripheral electronic equipment to re-enter specific system parameter settings into the memory of a replaced and unparameterised ECU.
- The present invention has an object to provide a vehicle braking system wherein the aforesaid problem is removed or substantially reduced.
- According to the invention there is provided a vehicle braking system including means operable to provide a signal indicative of vehicle loading, load responsive means responsive thereto and to a braking signal indicative of intended vehicle deceleration for controlling braking force produced by brake actuators of the vehicle said load responsive means comprising a parameterisable electronic braking control unit with a main configuration memory for storing parameters particular to the vehicle for control of vehicle brake force according to vehicle loading characterised in that said system includes a further electronic storage memory wherein said parameters particular to the vehicle are permanently retainable and means to effect entry of said parameters from said further memory to the main configuration memory of an unparameterised electronic braking control unit.
- More especially, the invention provides a trailer vehicle braking system including means operable to produce a signal indicative of vehicle loading, load responsive means responsive thereto and to a braking signal indicative of intended vehicle deceleration for controlling braking force produced by brake actuators of the vehicle said load responsive means comprising a main parameterisable electronic braking control unit with a main configuration memory for storing braking parameters particular to the vehicle for control of vehicle brake force according to vehicle loading a further electronic control unit including a configuration memory storing parameters particular to management of the vehicle and also a further electronic storage memory wherein said braking parameters particular to the vehicle are also permanently retainable and means operable to effect entry of said parameters from said further electronic memory to the main configuration memory of another unparameterised electronic braking control unit when substituted for said main unit.
- According to another aspect of the invention there is provided a trailer vehicle braking system including means operable to produce a signal indicative of vehicle loading, load responsive means responsive thereto and to a braking signal indicative of intended vehicle deceleration for controlling braking force produced by brake actuators of the vehicle said load responsive means comprising a main parameterisable electronic braking control unit with a main configuration memory for storing braking parameters particular to the vehicle for control of vehicle brake force according to vehicle loading a further electronic vehicle management control unit including a further configuration memory for storing management parameters particular to management of the vehicle and wherein said main control unit includes additional electronic storage memory wherein said parameters particular to management of the vehicle are also retainable and means operable to effect entry of said management parameters from said additional memory to a configuration memory of an unparameterised electronic control unit when substituted for said vehicle management control unit.
- In order that the invention may be more clearly understood and readily carried into effect the invention will now be further described by way of examples with reference to the accompanying drawings of which
- FIG. 1 illustrates a two-line trailer compressed air braking system with electronic load sensing adapted according to one embodiment of the invention; and
- FIGS.2-6 illustrate in schematic manner the operation of a preferred system.
- Referring to FIG. 1, a semi-trailer has three braked axles of respective pairs of
wheels 1, 2 and 3 with respective compressed air operated brakes and controlled air suspensions represented by references 1 b, 2 b and 3 b the pressures in which depend upon the loading of the trailer. A conventional trailer reservoirsupply line coupler 10 is connected in operation via lines (shown heavy) to derive pressure from a tractor to a trailer reservoir 11 via a maneuvering park valve 12 (park and shunt valve) and arelay emergency valve 14 and also to spring brake parking sections of doublediaphragm tandem actuators respective wheels 2 and 3 of two of the axles. If desired the functions of thevalves control line coupler 20 is connected in operation to provide a control input from the tractor vehicle to therelay emergency valve 14, the delivery from which is an input to a systemcontrol valve assembly 22 of an ECU 26 having electronics 21 with anelectrical plug coupler 30 to the tractor and deriving suitably proportional service brake pressure from the trailer reservoir 11 to respectiveservice brake chambers - The ECU26 includes a rain configuration data memory and electronics 21 for specific braking related vehicle parameters which enable it to control the
valve assembly 22 to supply braking pressure to the brake actuators appropriate to the loading and operating condition of the particular trailer. This memory is parameterised by the trailer builder using specialised equipment, to enable the function of the ECU to be matched to the particular vehicle, in a manner which is analogous to setting up of a conventionally mechanically operable variable load valve in a purely pneumatic system. Thus ECU 26 will determine the delivered basic pressure or inshot pressure established at onset of braking and thereafter provide appropriate graduation of brake pressures between tare weight and full load braking pressure curves for the particular trailer. It will further be understood that it is desirable for a vehicle operator to be able to replace a damagedECU 26 with minimal delay or complication despite the fact that an ECU parameterised with vehicle parameters specific to the vehicle will not in general be readily available even from specialist automotive components or parts distributors. - In the system of FIG. 1 there is included trailer diagnostic and information means including a further electronic control unit (ECU)27 adapted to receive, from sensors (not shown) connected to
inputs 31, indications of the locked or interlocked status of trailer body rear door locks, trailer body temperature, trailer reversing obstacle detection, tire pressure monitoring and information for determining imminence of servicing requirements based upon trailer use. The ECU 27 can communicate such information visibly or audibly to the tractor vehicle driver or to one or more remote information control stations via radio or satellite links. For the purpose of itsfunction ECU 27 also includes a main configuration data memory. The ECU 27 also has additional specific memory capacity wherein specific vehicle parameters are stored consequent upon the vehicle builder parameterising the main memory of thebraking ECU 26. - The ECU26 includes multipin socket connections 32 to a readily connected multiplug communication link and
coupler 33 via enabling inter alia detection of substitution of an unparameterised ECU, as a replacement for a damagedcrucial braking ECU 26. TheECU 27 can thereby initiate a function for newly parameterising thereplacement ECU 26 using stored parameters specific to the particular trailer. - In a preferred embodiment of a trailer braking system according to the invention the ECU's26 and 27 are provided with respective
electronic sub-systems data communication link 33 between the ECU's 26 and 27 permits parameterising communication between in each case the additional data memory of the ECU and the main configuration data memory of the other. Thedata communication link 33 transmits flag signals betweenECU 26 and ECU 27 whereby each can indicate to the other, detection of a “new ECU” (44, 54) and or imminent “data update” (43, 53). In FIGS. 2-6 “TRUE” present signals are indicated by hatching. Further, validity presently stored braking or management data is represented respectively by hatching or cross-hatching ofmemories - When the trailer is manufactured it is prepared for service as represented in FIG. 3 with each ECU initially presenting a “new ECU” flag signal. Using external computing equipment, the trailer manufacturer enters initial parameterising data to
system 40 which parameterises theconfiguration data memory 41, according to specific entered vehicle characteristic data. This data determines specified required computed responses of the trailer brakes to brake pressure signals from a tractor vehicle relative to loads carried by the trailer. - Following the described initial parameterising as represented at34 of FIG. 3 of the
configuration data memory 41 ofECU 26, as seen represented in FIG. 4 in a subsequent parameterising cycle, a “new ECU”flag signal 43 ofsystem 40 clears and 40 sets a “data update”flag signal 43 which with a “new ECU”flag signal 54 ofsystem 50 permits the new data to be copied frommemory 41 into theadditional memory 52 of 27. - Similarly, during a further parameterising cycle, the
configuration data memory 51 forECU 27 presenting a “new ECU” signal, is initially programmed with additional vehicle management data by the manufacturer from the external computing equipment. In yet another cycle, with a present “data update” flag signal ofsystem 40, copying of the management data contents ofconfiguration data memory 51 to thememory 42 ofECU 26, takes place. The resulting normal operable state of the parameterised system is then as illustrated in FIG. 5. - For normal operation of the trailer vehicle and its brakes in service the configuration data memories of ECU26 (braking) and ECU 27 (other parameters namely distance logging and other diagnostic parameters) are used as the basis of operation and management of the trailer vehicle. However in the event of one ECU, especially the
crucial braking ECU 26, being damaged and requiring replacement a standard but unparameterised replacement unit may be purchased and fitted by the operator. When the system is re-energised with such replacement correctly installed, the presence of the new ECU is indicated by presence of a “new ECU” flag signal (FIG. 6) to initiate copying of contents ofmemory 52 into theconfiguration data memory 41 ofECU 26. - Although not described in detail in the foregoing, it will be appreciated by the skilled person that the
communication link 33 betweenECU 26 and ECU 27 may preferably comprise a suitable multicore conductor or optical connection which carries digital signal elements making up not only the flagging signals for initiating copying of stored parameters between respective memories as described but also the parameters in digitised form along with check code elements bits. The clock rate for such transfer of information is preferably a subs multiple of a much higher operating clock rate governing the incremental brake pressure control and wheel antilock control if provided. - In the described embodiment, in addition to means whereby entry into a
replacement ECU 26 of crucial braking parameters from thefurther memory 52 according to the invention, withsub-system 40 of thebraking control ECU 26 also provided with theadditional memory capacity 42, it is possible for thevehicle management ECU 27 to be replaced and reparametised with valid management information especially that relating to servicing intervals of the vehicle. - The invention therefore provides the substantial advantage to a trailer operator that a potentially widely available unparameterised stock individual replacement ECU may be immediately parameterised for a particular trailer upon installation thereof, by copying crucial data from within a distinct intact system of the vehicle without any need for external specialised computer equipment. Vehicle down-time and cost is therefore much less than may otherwise be the case.
