Definitions
- the invention relates to a method and a device for improving the functional reliability of an electronic control device, in particular for actuating a clutch and / or a transmission in a vehicle drive train.
- Automated clutches are increasingly being used in modern motor vehicles, preferably in conjunction with automated manual transmissions. This not only increases driving comfort, it also reduces fuel consumption, as the vehicle is driven in a long gear as a result of suitably designed electronic controls and programs.
- the invention has for its object to improve the functional reliability and reliability of such electronic control devices.
- a first solution of the object of the invention is achieved with a method for improving the functional reliability of an electronic control device, in particular for actuating a clutch and / or a transmission in a vehicle drive train, which contains the following steps: Determine whether a position controller error, which is defined by the fact that an electrical actuator is controlled by a control signal for moving to a target position deviating from a current actual position and the target position does not move, is present, and if so,
- the “EMC flag” advantageously remains set for at least a predetermined period of time.
- the method is preferably such that when the “EMC flag” is set, no torque reaction on the vehicle drive train that is unexpected for the driver can take place.
- the electric actuator is an actuator for actuating a clutch arranged between an engine and a transmission of a vehicle
- the EMC flag is advantageously only reset when the transmission is in a neutral gear or the clutch torque is zero after the end of the position controller error or an intention to shift is determined or the clutch is opened to stop.
- the EMC flag is reset after the ignition is switched off, then a check is carried out to determine whether a position controller error is present and, if not, a shutdown step is carried out.
- a device for improving the functional reliability of an electronic control device in particular for actuating a clutch and / or a transmission in a vehicle drive train, which contains an electric actuator fed by a power amplifier with an actuator, one Sensor for detecting the position of the actuator, a current measuring device in a feed line to the actuator and a the output stage, the sensor and the current measuring device connected electronic control unit with a microprocessor and associated memory devices, which depending on input signals generates an output signal for controlling the output stage in such a way that the actuator moves the actuator into a predetermined target position when functioning correctly, the operation of the control unit when a position controller error occurs according to a method according to one of claims 1 to 5.
- a further solution to the object of the invention is achieved with a method for improving the functional safety of an electronic control device for actuating a clutch and / or a transmission in a vehicle drive train, the control device containing a microprocessor with associated RAM, in which method the microprocessor with its RAM is set in a power-saving operating state when the supply voltage drops, in which the data in the RAM are held until a predetermined minimum voltage is undershot and the microprocessor with its RAM is reset to its normal operating state when a predetermined threshold voltage is exceeded.
- a further solution to the object of the invention is achieved with a device for improving the functional safety of an electronic control device for actuating a clutch and / or a transmission in a vehicle drive train, which contains a supply voltage source which is connected in parallel to a capacitor to the microprocessor with associated RAM, a logic circuit connected to the supply voltage source, which if the supply voltage drops an operation according to the above-mentioned methods in order to keep the data in the RAM as long as possible by supplying the RAM with voltage from the capacitor.
- the invention is generally suitable for electronic control devices for actuators.
- FIG. 1 is a block diagram of a control device with which EMC-related errors can be identified
- FIG. 3 shows a block diagram of a device which is protected against brief failures of the supply voltage.
- an actuator 10 designed as an electric motor, with which, for example, an actuator 12 of an automated clutch of a vehicle can be moved, is connected to a power source 22 via four electronic switches 14, 16, 18 and 20. Depending on whether the switches 14 and 18 are closed and the switches 16 and 20 are open or the switches 14 and 18 are open and the switches 16 and 20 are closed, the actuator 10 moves the actuator 12 in one direction or the other.
- the switches 14, 16, 18 and 20 can be, for example, FETs, which are contained in an output stage 24 shown in dashed lines, which is controlled by an electronic control unit 26, which is constructed in a manner known per se, and a microprocessor with a memory with random access (RAM) and a read only memory (ROM).
- Algorithms are stored in the ROM of the control device 26, according to which the control device controls the actuator 10, for example by means of pulse-width-modulated control of the switches, depending on signals at its inputs. Since a clutch for smooth operation and transmission of a precisely predetermined torque must be controlled very precisely, the position of the actuator 12 is preferably detected by a position sensor 28 and reported back to the control unit 26, so that the clutch is actuated in a controlled manner.
- the actuator 10 does not move to this desired position despite a correct specification of the desired position of the actuating member 12.
- the control unit 26 recognizes this as a position controller error which also occurs when, for example, the transmission path between the actuator 12 and the clutch itself, for example between a master cylinder and slave cylinder, is blocked or interrupted. It is known that in this case the control system goes into a shutdown mode, which is only reset when the ignition is switched off and on again.
- a blockage in driving operation can occur when the distance between a master cylinder and a slave cylinder (hydraulic transmission path; the actuator 12 is then connected to the master cylinder) widens due to temperature expansion or inflates at low temperatures. It may happen that the clutch is not completely disengaged, which can be seen when the position sensor 28 is attached directly behind the hydraulic transmission link, for example to the clutch release lever. In the event of the clutch not being fully disengaged, a strategy is already known which eliminates this error without ending in a shutdown mode.
- a blockage of the distance between actuator 10 and clutch, which can occur in any actuation position of the clutch, would, if the system does not change to the shutdown state, in which the power supply to actuator 10 is switched off, lead to thermal destruction of the actuator 10 and / or cause further damage to the actuating mechanism.
- a position controller error caused by electromagnetic radiation is i. A. dependent on the frequency and field strength of the radiation and can occur in any actuation position of the clutch.
- a position controller error cannot be distinguished from a position controller error which is attributable to other faults, such as blockage, pinching or pinching off a hydraulic hose, etc. Since an EMC influence generally only lasts for a short time, it is advisable to detect a position controller error due to a lack of electromagnetic compatibility, so that the activation of a resulting emergency operation strategy is left again without the driver's intervention.
- the controlled electronic switches 14, 16, 20 and 18 are not or not correctly switched through, so that the control of the actuator 10 is faulty; a "hot path" can be switched, for example by switching switches 18 and 20 and / or 14 and 16 at least partially.
- a current measuring device 30 is provided in the current path to the motor, which is connected to an input of the control unit 26.
- a first step 40 of the routine process it is determined whether the ignition is switched on. If this is the case, it is checked in step 42 whether a position controller error is present, which is recognized by the fact that the position sensor 28 does not move into its desired position. If a position controller error is detected, see above it is checked in step 44 whether the current in the motor path (measured by means of the current device 30) is above a predetermined value for a longer period of time. If this is the case, there is a blocking error and a blocking flag is set to 1 in step 46. If there is no blocking error, this is evaluated as an EMC error and an EMC flag is set to 1 in step 48.
- step 50 the output stage (eg 24 in FIG. 1) is put out of operation, so that damage or other malfunction of the system is avoided. From step 50, the method routinely returns to step 40.
- step 52 determines whether one of the conditions of transmission in neutral or clutch torque equal to zero or intention to shift exists or clutch is present for stopping. If this is the case, the EMC flag is reset to zero in step 54.
- the aforementioned conditions are examples of the fact that there are no unexpected torque reactions in the drive train when the clutch resumes normal operation or the power stage is started up. It is then checked in step 56 whether the blockade flag is set. If this is not the case, the output stage is put into operation in step 58, so that a clutch is actuated in accordance with an active program. If the blockade flag is set, the power stage cannot be put into operation.
- step 40 If it is determined in step 40 that the ignition is switched off, for example to stop the vehicle, then the possibly set EMC flag is reset in step 60. In step 62 it is then checked whether a position controller error is present. If this is not the case, a shutdown routine runs, within which the clutch is closed, for example, when a gear is engaged, in order to support the standstill of the vehicle by the engine idling torque.
- the described method ensures that an emergency operation program, which is activated, for example, after or in step 50, is automatically exited if an EMC error does not persist.
- control devices are able to withstand an interruption in the supply voltage for a very short period of time, for example of about one millisecond, without an undervoltage reset. This time period depends heavily on the type of voltage dip and the current system status. The worst case is when, for example, the supply voltage goes to zero due to unsafe contact of a pole terminal while an actuator is running. The voltage buffering is then taken over by a capacitor, which normally has the function of suppressing interference signals in order to stabilize the supply voltage.
- FIG. 3 shows an electronic control unit 26, which could be functionally connected like the control unit according to FIG. 1, with a microprocessor, RAM and ROM. Numerous functions can be controlled with the control device 26, as indicated by the large number of outputs.
- the control device 26 is supplied with voltage via a supply voltage source 70, to which a buffer capacitor 72 is connected in parallel.
- the supply voltage is detected by a logic circuit 74, which is connected to an input of the control device 26, with which various operating modes or operating states of the control device 26 can be switched.
- the logic circuit 74 If the logic circuit 74 detects a voltage drop, for example the supply voltage drops below 6 volts, the logic circuit device 74 generated interrupt signal the microprocessor with its internal volatile memory (RAM 30) in a power-saving mode (power down mode).
- the supply voltage is buffered by the external buffer capacitor 72.
- other electronics such as output stages, external control devices, etc., are decoupled from the control of the processor of control device 26, and their state is thereby frozen. Actuators that may be in motion stop immediately. This further reduces power consumption.
- the current required by the microprocessor in the power-saving operating state is, for example, approximately 100 ⁇ A. This means that the data can be held in RAM at a voltage of, for example, 2.5 volts.
- the microprocessor When the supply voltage rises again to more than 6 volts, the microprocessor is reset to its normal operating state via a reset signal generated by the logic circuit 74 without loss of the data of the RAM, by resuming its control and regulating functions.
- the flawless nature of the data in the RAM can be ensured by carrying out a checksum calculation of the data in the RAM after the reset, the checksum possibly with a power down
- the capacitance of the buffer capacitor is 10 ⁇ F and its voltage is 5 volts, the following energy can be stored:
- the voltage supply can be calculated for a period of 330 ms:
- the above examples can be modified in many ways. For example, they can be combined with each other.
- the logic circuit 74 can be integrated in the control unit, etc.
