Definitions
- the invention relates to a method for controlling a tire pressure monitoring system of a vehicle, which has an electronic control unit with a receiving unit, a main memory and a buffer memory, as well as a tire sensor module for each vehicle wheel with a transmitter/receiver unit, a battery and a pressure sensor, with the tire sensor modules each in transmit a sensor data set by radio at certain time intervals and after triggering, which contains at least one individual identification code, a tire pressure value and trigger information.
- Vehicles of the so-called class M1 i.e. passenger cars and mobile homes, which from 1 November 2012 received a new type approval or from 1.
- Vehicles newly registered since November 2014 must be equipped with a tire pressure monitoring system in the EU in accordance with EU Regulation 661/2009. With this tire pressure monitoring system, the tire pressure of the vehicle wheels is determined and a warning is given in the event of incorrect tire pressure or a loss of pressure in one of the wheel tyres.
- the increasing use of tire pressure monitoring systems and the associated driving with the correct tire pressures should reduce fuel consumption and CO2 emissions from vehicles and prevent accidents caused by incorrect tire pressures and tire damage.
- Indirect tire pressure monitoring systems in which deviations in tire pressure from the target pressures are detected by the wheel speed sensors of the respective ABS brake system based on the speed differences, which occur due to changed rolling radii of the vehicle wheels, have not been able to establish themselves on the vehicle market. Therefore, these days almost exclusively direct effective tire pressure monitoring systems, in which the tire pressures are recorded directly via pressure sensors, which are either external, i.e. outside the respective wheel tire, with a connection to the tire valve on the wheel rim concerned, or internal, i.e. inside the respective wheel tire on the wheel rim or the wheel tire are.
- the pressure sensors are usually part of tire sensor modules, which each have a transmitter and receiver unit and a battery in addition to the pressure sensor.
- a temperature sensor and an acceleration sensor can also be arranged on it.
- the tire sensor modules transmit a sensor data set via radio at certain time intervals and after a trigger, which contains at least an individual identification code (abbreviated: sensor ID), a tire pressure value and trigger information.
- sensor ID individual identification code
- trigger information e.g., a tire pressure value
- sensor data sets are received and processed by an electronic control unit.
- the control device is connected to a display device, which is arranged, for example, in the area of the driver's seat in the towing vehicle, and on which the tire pressures or at least warning signals in the event of incorrect tire pressures are displayed.
- the control device can also be connected wirelessly to a display device on the trailer of a commercial vehicle or to a mobile display and operating device of a vehicle driver via a radio link.
- a tire pressure monitoring system intended especially for heavy commercial vehicles is described in the information sheet 815 020 229 3 "OPTITIRETM tire pressure monitoring for commercial vehicles - system description" from WABCO GmbH with regard to its design, its mode of operation and its operation.
- This information sheet can be downloaded from the company's website as a PDF document from the Internet.
- the defective vehicle wheel mounted on a vehicle axle can be exchanged for a spare wheel that is carried along.
- the wheel positions of the two vehicle wheels concerned are swapped, so that incorrect vehicle wheels are displayed to the driver on the said information device for these two wheel positions if no corrections are made.
- the assignment of the wheel positions to the tire sensor modules remains unchanged.
- a new vehicle wheel with a new individual identification code can be mounted on the wheel position at which the vehicle wheel with the tire damage was previously, as an alternative to mounting a spare wheel that is being carried along found.
- the control unit receives the sensor data records of the newly fitted vehicle wheel with a previously unknown sensor ID, and the sensor data records of the removed vehicle wheel with the known sensor ID are no longer received.
- the sensor ID changes at the relevant wheel position, which is to be brought to the attention of the control unit in a suitable manner.
- the control unit also does not know anything about this without further measures and displays incorrect values for the wheel position.
- a method described in DE 196 08 478 A1 for assigning wheel positions to tire sensor modules requires a tire pressure monitoring system with multiple receiving antennas, which are each arranged near a wheel position on the vehicle frame and connected to an electronic control unit.
- the wheel positions are assigned to the tire sensor modules in accordance with the highest signal level at each of the receiving antennas when the sensor data sets transmitted by the tire sensor modules at specific time intervals are received.
- DE 102 50 942 A1 discloses a method for assigning wheel positions to tire sensor modules, in which the wheel positions are assigned while driving based on changes in tire pressures due to dynamic driving processes such as cornering, braking and acceleration processes.
- the present invention is therefore based on the object of presenting a method for controlling a tire pressure monitoring system of a vehicle of the type mentioned at the beginning, with which the assignment of the wheel positions to the tire sensor modules after a wheel change is possible for a driver or fitter comparatively quickly and easily.
- This object is achieved by a method which has the features of claim 1.
- Advantageous developments of this method are defined in the dependent claims.
- the invention relates to a method for controlling a tire pressure monitoring system of a vehicle, in particular a commercial vehicle, which has an electronic control unit with a receiving unit, a main memory and a buffer memory, as well as a tire sensor module RSM with a transmitter/receiver unit, a battery and a pressure sensor for each vehicle wheel , wherein the tire sensor modules RSM transmit a sensor data set SDS via radio at specific time intervals and after triggering, which contains at least one individual identification code (sensor ID), a tire pressure value and trigger information.
- a tire sensor module RSM transmit a sensor data set SDS via radio at specific time intervals and after triggering, which contains at least one individual identification code (sensor ID), a tire pressure value and trigger information.
- a detection function EF and then, conditionally, a test function PF are carried out, that while the detection function EF is being carried out, all Tire sensor modules RSM in a sequence characterizing the wheel positions, it is expected that the control unit will receive the sensor data sets SDS of the triggered tire sensor modules and will store them in the buffer memory in the order in which they are received, and that the sensor data sets SDS stored in the buffer memory will be checked for plausibility in the test function and a positive test result are stored in the main memory instead of older sensor data sets.
- the control method according to the invention therefore uses a tire pressure monitoring system of a vehicle, which has an electronic control unit with a receiving unit, a main memory and a buffer memory and a tire sensor module with a transmitting and receiving unit, a battery and a pressure sensor for each vehicle wheel.
- the main memory are at a first Commissioning of the control unit, the basic vehicle configuration data has been permanently stored, for example the presence of three vehicle axles, each with two wheels per vehicle axle. These vehicle configuration data can only be changed using separate diagnostic software and therefore remain constant when the described method according to the invention is used.
- the tire sensor modules each transmit a sensor data set by radio at specific time intervals and after a triggering, which contains at least one individual identification code (sensor ID), a tire pressure value and trigger information.
- TPMS Tire Pressure Monitoring System
- the tire sensor modules can also be triggered by means of a suitable permanent magnet, which is held briefly in the vicinity of the relevant tire sensor module for this purpose.
- a triggered signal is known to differ from a regular, automatically transmitted signal, so that an erroneous assignment of a randomly received sensor signal is avoided.
- the detection and assignment of the wheel positions to the tire sensor modules can be carried out relatively quickly and easily before the start of a journey without any further prerequisites. Since the detection function EF of the method according to the invention is executed before the start of each journey, regardless of whether a wheel change has taken place or not, it can also run without a result, ie without a new assignment of wheel positions to specific tire sensor modules. If no triggered sensor signals were received while the detection function EF was being executed, the test function PF is not carried out.
- the test function PF is preferably carried out after the end of the detection function EF during the subsequent journey of the vehicle. In this way it can be ensured that the sequence of the detection function EF has ended.
- the detection function EF is started when the ignition or the on-board electrical system of the vehicle is switched on and ended after a specified running time A (t>AL).
- the running time AL of the detection function EF is set to a period of time in which all tire sensor modules can be easily triggered by a human in the intended sequence.
- the runtime AL of the detection function is measured in such a way that all tire sensor modules can be easily triggered in the intended order, it can happen that the driver or mechanic is held up during the triggering process and therefore does not manage to find all tire sensor modules within the runtime AL of the to trigger the acquisition function.
- the runtime AL of the detection function EF is extended until the start of the journey if at least one triggered sensor data set SDS has been received by the control unit, and that the detection function EF is ended without a result if the triggered sensor data sets SDS of all tire sensor modules have not been received by the start of the journey of the vehicle have been received.
- Sensor data records from non-triggered tire sensor modules received during the runtime AL of the detection function are ignored, since they are irrelevant for the assignment of the wheel positions to the tire sensor modules.
- the sensor data sets of triggered and non-triggered tire sensor modules can be distinguished using the trigger information in the sensor data sets, for example a “1” for triggered and a “0” for non-triggered.
- each sensor data record of a triggered tire sensor module is advantageously confirmed by the output of an acoustic and/or optical signal.
- an acoustic confirmation of receipt signal for example, a controllable drain solenoid valve of a compressed air brake system of the vehicle can be briefly opened once.
- a visual confirmation of receipt for example, the brake lights or the direction indicator lights of the vehicle can be switched on briefly once.
- the receipt of a number ns of received sensor data sets from triggered tire sensor modules corresponding to the number na of vehicle wheels, ie a complete number ns of received sensor data sets, can advantageously be confirmed by the output of an acoustic and/or optical signal.
- an acoustic confirmation of receipt signal for example, a controllable drain solenoid valve of the vehicle's compressed air brake system can be briefly opened twice in succession.
- a visual confirmation of receipt for example, the brake lights or the direction indicator lights of the vehicle can be briefly switched on twice in a row.
- the detection function is also ended prematurely if the drive engine of the vehicle is started before the end of the runtime Ati_ or the vehicle starts to move (vehicle speed VF > 0). If, for example, the vehicle was in an unsafe place when the wheel was changed and triggering was not possible there, the tire sensor modules can then be triggered in a secure parking lot, for example.
- the plausibility of the received sensor data sets from triggered tire sensor modules is determined, for example, when the wheel positions of at least two tire sensor modules are reversed compared to the wheel positions that were assigned to the two tire sensor modules before the journey was interrupted.
- the plausibility of the received sensor data sets from triggered tire sensor modules is also determined in the check function PF, for example, if at least one wheel position is assigned to a tire sensor module with a new sensor ID, and the sensor ID to which this wheel position was assigned before the journey was interrupted has been omitted .
- an acoustic and/or visual warning signal is output to draw the driver's or fitter's attention to the error and him if necessary, to cause the tire sensor modules to be triggered again after a restart of the detection function.
- the driver or fitter only has to switch off the ignition or the on-board electrical system and switch it on again.
- a controllable release solenoid valve of the vehicle's compressed air brake system can be briefly opened three times in succession.
- an optical warning signal for example, the brake lights or the direction indicator lights of the vehicle can be switched on briefly three times in a row.
- FIG. 1 shows a first part of the sequence of the method according to the invention for controlling a tire pressure monitoring system in the form of a schematic flowchart
- FIG. 2 shows a second part of the sequence of the method according to the invention for controlling a tire pressure monitoring system in the form of a schematic flowchart.
- FIGS. 1 and 2 show a possible sequence of the method according to the invention for controlling a tire pressure monitoring system of a vehicle in the form of a flowchart.
- the method is used to allocate wheel positions to the tire sensor modules RSM arranged in or on the wheel tires of the vehicle wheels after a break in travel, during which a wheel change may have taken place. If, for example, a wheel change took place during the break in travel, in which at least one vehicle wheel with a defective wheel tire mounted on a vehicle axle was replaced with a spare wheel that was carried along or with a new vehicle wheel, the wheel positions for the changed or newly mounted vehicle wheels must be assigned to the relevant ones tire sensor modules required. An update of the assignment of tire sensor modules to other than the previous wheel positions is also required when vehicle wheels to achieve even tire wear axle by axle or be exchanged page by page. The same applies when changing vehicle wheels with summer tires to vehicle wheels with winter tires.
- the method provides that the driver or fitter triggers the tire sensor modules of all vehicle wheels in a specified order, for example starting with the tire sensor module of the right front wheel clockwise around the vehicle to the tire sensor module of the left front wheel.
- the tire sensor modules each transmit a sensor data set via radio, which contains at least one individual identification code (sensor ID), a tire pressure value and trigger information.
- sensor ID individual identification code
- the wheel positions are determined by the sequence of triggering.
- the assignment of the wheel positions to the tire sensor modules within the tire pressure monitoring system takes place automatically using the control method described below. It is assumed here that the basic vehicle configuration data are permanently stored in the tire pressure monitoring system, for example the number of vehicle axles and the number of wheels per vehicle axle. These vehicle configuration data can only be changed using separate diagnostic software and therefore remain constant while the described method according to the invention is being used.
- a detection function EF is started (function start SO) after the ignition or the on-board electrical system of the vehicle is switched on.
- a time counter and a counter ns indicating the number of received sensor data sets SDS of triggered tire sensor modules RSM are initialized, ie set to the value zero.
- An electronic control unit then receives a sensor data set SDS sent by a tire sensor module RSM (method step S2), which may have been sent by the relevant tire sensor module due to a trigger or due to an expired time interval.
- step S3 it is checked whether the tire sensor module RSM of the received sensor data set was triggered or not, which is based on the trigger information (value "1" or value "0") in the sensor data set. If the verification of the triggering is positive, an acoustic and/or visual confirmation of receipt signal ES-1 is output as feedback for the driver or fitter (method step S4).
- an acoustic confirmation of receipt signal for example, a controllable drain solenoid valve of a compressed air brake system of the vehicle can be briefly opened once.
- a visual confirmation of receipt for example, the brake lights or the direction indicator lights of the vehicle can be switched on briefly once.
- method step S5 it is checked whether a sensor data set SDS of the tire sensor module with the same sensor ID has already been received and stored in a buffer ZS. If this is the case, the relevant sensor data set SDS in the buffer store ZS is overwritten with the currently received sensor data set SDS (method step S6). If no sensor data set SDS with the relevant sensor ID has yet been stored, the currently received sensor data set SDS is stored at the designated location in the buffer store ZS (method step S7) and in the subsequent method step S8 the counter ns for the signal data sets received as a result of a trigger SDS increased by one.
- method step S6 or method step S8 it is checked whether the number ns of sensor data sets SDS received as a result of a trigger corresponds to the number nn of vehicle wheels, i.e. whether sensor data sets of all vehicle wheels have been received (method step S9). If the test result is positive, ie the presence of a complete number of signal data sets SDS, an acoustic and/or optical receipt confirmation signal ES-2 is output in method step S10 to inform the driver or fitter.
- an acoustic confirmation of receipt signal for example, a controllable drain solenoid valve of the vehicle's compressed air brake system can be opened in succession in a defined sequence, for example twice for a comparatively short time and twice for a comparatively long time.
- the brake lights or the Direction indicator lights of the vehicle in a defined sequence are briefly switched on one after the other.
- the type and duration of the confirmation signal described can be set freely and can be combined with other confirmation signals if required.
- the detection function then ends normally (function end E1) and a test function PF is then carried out, which is shown in the flow chart of FIG. 2 and will be described later.
- method step S11 If the check for the presence of a complete number of sensor data sets SDS in method step S9 is negative, it is checked in method step S11 whether a running time A of the detection function EF, which is fixed at five minutes, for example, has already been reached or exceeded. If the test result is negative, a branch is made back before method step S2, in which another signal data set can be received. If the test result in method step S11 is positive, i.e. the runtime AL of the acquisition function EF has been reached or exceeded, it is checked in method step S12 whether the number ns of sensor data sets SDS received as a result of a trigger has reached or exceeded a specified minimum number ns_min.
- the detection function EF ends without result (end of function E2), ie without a new assignment of wheel positions to specific tire sensor modules. This also ends the control method according to the invention. If the test result is positive, the runtime AL of the detection function EF is increased in method step S13 by a time period Atz, which is fixed at five minutes, for example, and then a branch is made back before method step S2. This gives the driver or mechanic the opportunity to complete an incomplete sequence of trigger processes and thereby achieve a regular termination of the detection function EF.
- the test function PF is started (function start S0').
- the signal data records SDS received in the detection function EF and stored in the buffer store ZS are first checked for plausibility (method step S14).
- the plausibility of the received sensor data records SDS triggered tire sensor modules is determined, for example, when the wheel positions of at least two tire sensor modules are reversed compared to the wheel positions that were assigned to the two tire sensor modules before the journey was interrupted.
- the plausibility of the sensor data sets received from triggered tire sensor modules is also determined, for example, if at least one wheel position is assigned to a tire sensor module with a new sensor ID, and the sensor ID that was assigned to this wheel position before the journey was interrupted has been omitted.
- the test function PF is preferably only operated while the vehicle is driving, which ensures that the detection function EF described has been completed and the vehicle has left a workshop, for example.
- the sensor data sets SDS previously stored in the intermediate memory ZS are stored in a main memory HS of the control unit (method step S15), whereby the corresponding assignment of the wheel positions to the tire sensor modules given by the sequence of the previous triggering of the tire sensor modules in the subsequent control of the tire pressure control system TPMS.
- the test function PF ends (end of function E3) and thus also the control method according to the invention.
- an acoustic and/or visual warning signal WS is output in method step S16 to inform the driver or mechanic before the test function PF ends (function end E3).
- an acoustic warning signal for example, a controllable release solenoid valve of the vehicle's compressed air brake system can be briefly opened three times in succession.
- the brake lights or the vehicle's direction indicator lights for example, can be briefly switched on three times in succession as a visual warning signal.
- the assignment of the wheel positions to the tire sensor modules RSM can thus be carried out relatively quickly and easily after a break in travel without any further prerequisites.
