Definitions
- the present invention relates generally to brake solutions for motor vehicles being based on exhaust gas restriction. More particularly the invention relates to an exhaust brake system according to the preamble of claim 1 and a motor vehicle according to claim 8 The invention also relates to a method of controlling an exhaust gas brake according to the preamble of claim 9, a computer program product according to claim 16 and a computer readable medium according to claim 17.
- Exhaust brake systems for combustion-engine vehicles typically include a valve, which is arranged in the engine's exhaust passage. When the exhaust brake is activated, the valve is controlled to a position wherein it obstructs the exhaust gasses flowing from the engine. Thereby, the pistons in the engine experience an increased resistance during the engine's exhaust stroke, and consequently a brake effect occurs.
- US 6,810,850 discloses a solution according to which an exhaust restrictor is located in an exhaust system downstream of the engine's exhaust manifold.
- a controller determines a set pressure in the exhaust manifold correlated with speed of the engine. The controller then adjusts the restrictor to achieve and maintain the set pressure in the exhaust manifold.
- VVT variable geometry turbocharger
- the object of the present invention is therefore to provide a solution, which alleviates the problems above, and thus offers predictable, reliable and efficient exhaust brake function.
- the object is achieved by the initially described exhaust brake system, wherein the system includes a second pressure sensor adapted to register an input pressure in an air intake to the engine.
- the brake torque regulator includes a processing means, which is adapted to receive the registered input pressure, receive an engine para- meter reflecting a speed of the engine, model a gas exchange work performed by the engine and generate a reference parameter based on this model.
- the brake torque regulator also includes a control means that is adapted to receive at least the reference parameter, and based thereon, produce the control sig- nal. I.e., the control signal is produced, directly or indirectly, based on the registered exhaust gas pressure, the reference parameter and a set value, which designates a desired brake torque.
- control signal is generated on the basis of a model describing a gas exchange work being performed by the engine.
- a feedback loop may be used to determine how well a current adjustment of the exhaust brake valve matches the desired brake torque.
- the valve can be adjusted very accurately irrespective of, whether or not, one or more components in the control chain deviate reasonably from their nominal characteristics.
- the processing means is adapted to receive the set value, and on the further basis thereof, generate the reference parameter in the form of a first modeled parameter reflecting an estimation of the exhaust gas pressure in the exhaust conduit.
- the gas exchange model for the engine implemented by the processing means bases its generated estimation of the exhaust gas pressure on the input pressure registered in the air intake to the engine, the speed of the engine and the set value.
- control means is further adapted to receive this estimation of the exhaust gas pressure and receive the exhaust gas pressure registered in the engine's exhaust conduit.
- control means is adapted to produce the control signal to the adjustable valve. Consequently, the control means may produce the control signal in order to minimize an error between the registered and the estimated exhaust pressure.
- control means is specifically adapted to implement a proportional-integrating-derivative algorithm. Namely, this vou- ches for a desirable balance between response time, accuracy and stability.
- the processing means is instead adapted to receive the registered exhaust gas pressure.
- the processing means is adapted to generate the estimated reference parameter in the form of a second modeled parameter reflecting an estimation of the desired brake torque.
- the gas exchange model for the engine implemented by the processing means bases its estimation of the desired brake torque on the input pressure registered in the air intake to the engine, the exhaust gas pressure registered in the exhaust conduit and the speed of the engine. Consequently, the control means may produce the control signal in order to minimize an error between the estimated desired brake torque and the actually desired bra- ke torque (designated by the set value).
- the control means is specifically adapted to implement a proportional-integrating- derivative algorithm, which provides a desirable balance between response time, accuracy and stability.
- the object is achieved by the motor vehicle described initially, wherein the vehicle includes an internal combustion engine and the above-proposed exhaust brake system.
- This system is configured to apply an adjustable brake torque with respect to at least one drive axis of the engine.
- the object is achie- ved by the method described initially, wherein an input pressure is registered in an air intake to the engine; an engine parameter is registered that reflects a speed of the engine, and a reference parameter is generated based on a model of a gas exchange work performed by the engine and in response to the registered input pressure and the registered engine parameter. Finally, the control signal is produced on the further basis of the reference parameter.
- the object is achieved by a computer program product directly loadable into the internal memory of a computer, comprising software for controlling the above proposed method when said program is run on a computer.
- the object is achieved by a computer readable medium, having a program recorded thereon, where the program is to make a computer control the above proposed method.

- Figure 4 shows a flow diagram illustrating the general me- thod according to the invention.
- FIG. 1 shows a block diagram over an exhaust brake system according to a first embodiment of an exhaust brake system 100 according to the invention.
- the pro- posed system 100 operates on an internal combustion engine 1 10 of a vehicle, wherein the engine 1 10 receives input air A in via an air intake 140 and emits exhaust gasses E out via an exhaust conduit 150.
- the system 100 includes an adjustable valve 135, a first pressure sensor 155, a second pressure sensor 145 and a brake torque regulator 160, here in the form of an electronic control unit (ECU).
- This regulator 160 includes a control means 130 and a processing means 120.
- Each of the means 120 and 130 may be implemented in hardware as well as in firmware or software. I.e. one or both of the means 120 and 130 respectively may be represented by a physical unit, or a firmware/software module.
- the adjustable valve 135 is arranged in the exhaust conduit 150.
- the valve is adapted to obstruct the exhaust gasses E out in the conduit 150 in response to a control signal C.
- the valve 135 is preferably connected to a lever and piston arrangement (not shown), which for instance is electronically, pneumatically or hydraulically operated.
- a brake effect is accomplished if the control signal C, which may be a pulse width modulated (PWM) electrical or optical signal, controls at least one obstructive ele- ment of the valve 135 to attain a position in which the exhaust gasses experience a resistance being higher than otherwise.
- PWM pulse width modulated
- the brake torque either counteracts a drive torque being produced during the engine's 1 10 combustion phase, or genera- tes a torque that reduces the vehicle's kinetic energy (or momentum), e.g. when the vehicle rolls down a slope.
- a brake effect occurs with respect to the engine's 1 10 drive axis (i.e. the axis devised to convey propelling energy to the vehicle's drive wheels).
- this is a desirable complement to the conventional brake system.
- the first pressure sensor 155 is adapted to register an exhaust gas pressure P m in the exhaust conduit 150 between the engine 1 10 and the valve 135. Naturally, for a given amount of exhaust gasses emitted from the engine 1 10, the exhaust gas pressure P m becomes higher if the adjustable valve 135 is adjusted to a more obstructive position.
- the control means 130 is adapted to receive the exhaust gas pressure P m registered by the first pressure sensor 155, and produce the control signal C at least partially based on this pressure P m .
- the control signal C is also produced, directly or indirectly, based on a set value T req designating a desired brake torque.
- the set value T req may either be assigned manually by an operator/driver (e.g. via a pedal or a lever), or this parameter may be generated automatically by a control means in the vehicle, for instance being adapted to limit the amount of white smoke emitted, or to accomplish a quick heat- up of the engine 1 10.
- the processing means 120 is adapted to receive an input pressure P in registered by the second pressure sensor 145, which is arranged in the air intake 140. Additionally, the processing means 120 is adapted to receive an engine parameter rpm reflecting a speed of the engine 1 10 (e.g. the number of revolutions per unit time performed by the engine's 1 10 crank axle). In response to these parameters rpm, P in and T req , the processing means 120 is adapted to gene- rate a reference parameter P m-mod -
- the processing means 120 is adapted to model a gas exchange work being performed by the engine 1 10.
- the processing means 120 produces the refe- rence parameter in the form of a first modeled parameter P m - mOd that reflects an estimation of the exhaust gas pressure in the exhaust conduit 150 between the engine 1 10 and the valve 135.
- the first modeled parameter P m - moc i is produced based on the engine speed rpm, the exhaust gas pressure P m and the set value T req .
- the control means 130 is adapted to receive the reference parameter (i.e. here the first modeled parameter P m - moc i) and produce the control signal C on the basis thereof in addition to the above-mentioned exhaust gas pressure P m .
- the control means 130 is specifically adapted to implement a proportional- integrating-derivative algorithm, which in turn, is adapted to produce the control signal C in order to minimize an error between the registered exhaust gas pressure P m and the first modeled parameter P m - mOd (representing the processing means' 120 esti- mation of this pressure).
- a stabile and accurate and adjustment of the valve 135 can be performed, such that an actual brake torque applied to the vehicle's drive axis quickly approaches the desired brake torque indicated by the set value
- Figure 2 shows a block diagram over an exhaust brake system according to a second embodiment of an exhaust brake system according to the invention. All reference labels occurring in Figure 2, which are identical to those used Figure 1 designate the same entities, parameters and variables as those described above with reference to this figure.
- control means 130 is adapted to receive a reference parameter T mOd and produce the control signal C based thereon. In this case, however, the control means 130 also receives the set value T req directly.
- control means 130 is specifically adapted to implement a proportional-integrating-derivative algorithm, which in turn, is adapted to produce the control signal C in order to minimize an error between the set value T req and the second modeled para- meter T mod .
- the processing means 120 is adapted to receive both the registered input pressure P in and the registered exhaust gas pressure P m in addition to the engine parameter rpm that reflects the speed of the en- gine 1 10. Based on these parameters P in , P m and rpm, the processing means 120 is adapted to generate the reference parameter T mod , which here reflects an estimation of the desired brake torque designated by the set value T req .
- the processing means 120 is adapted to apply a model of the gas exchange work performed by the engine 1 10, which is essentially reverse to the model applied by the control means shown in Figure 1 .
- a model reversion is rendered relatively uncomplicated if the modeled relationship between the brake torque and the exhaust gas pressure is linear.
- the model of the gas exchange work performed by the engine 1 10 may derived by applying a polynomial regression algorithm to least-square fit a set of measurement data from the engine 1 10.
- the resulting polynomial includes a respective term pertaining to the input pressure P in , the exhaust gas pressure P m and the engine speed rpm.
- the polynomial further includes an offset term and possibly a number of cross terms and/or relevant temperature parameters.
- Tmo d C 0 + C 1 - P 1n + C 2 - P m + C 3 - TPm + C 4 - Ti n + C 5 - T n may be used, where in addition to the above, C 4 and C 5 are constants, T in designates the temperature in the air intake 140, and
- T m designates the temperature in the exhaust conduit 150 between the engine 1 10 and the valve 135.
- FIG 3 schematically depicts a motor vehicle 200 in the form of a truck, which is equipped with the proposed exhaust brake system 100.
- the vehicle 200 includes an internal combustion engine 1 10 having an air intake 140 and an exhaust conduit 150 for receiving air A in and emitting exhaust gasses E out respectively.
- the exhaust brake system 100 is configured to apply an ad- justable brake torque with respect to at least one drive axis of the engine 1 10 by adjustment of a valve in the exhaust conduit 150, such that the exhaust gasses E out from the engine 1 10 experience an increased resistance.
- the system 100 includes, or is associated with, a computer readable medium 1 70 (e.g. a memory module) storing a program, which is adapted to make at least one control unit in the vehicle 200 execute the above-described steps.
- a computer readable medium 1 70 e.g. a memory module
- a program which is adapted to make at least one control unit in the vehicle 200 execute the above-described steps.
- a first step 410 receives a set value designating a desired brake torque to be applied to a vehicle's drive axis; a second step 420, registers an exhaust gas pressure in an exhaust conduit from an internal combustion engine of the vehicle; a third step 430, registers an input pressure in an air intake to the engine; and a fourth step 440 registers an engine parameter reflecting a speed of the engine.
- the steps 410, 420, 430 and 440 may be completed in any order relative to one another, as well as in parallel.
- a step 450 follows, wherein a reference parameter is generated.
- the reference parameter ei- ther reflects an estimation of the exhaust gas pressure in the exhaust conduit, or an estimation of the desired brake torque.
- the reference parameter is generated in response to (i) the input pressure, the engine parameter and set value, provided that the reference parameter reflects an estimation of the exhaust gas pressure; and (ii) if the reference parameter reflects an estimation of the desired brake torque, the reference parameter is generated in response to the input pressure, the exhaust gas pressure and the engine parameter.
- a step 460 produces a control signal for the ad- justable valve, so as to obstruct the exhaust gasses from the engine, and thus accomplish a brake torque during the engine's exhaust stroke to counteract a drive torque produced during the engine's combustion phase.
- the control signal is produced based on the reference parameter and either of the exhaust gas pressure and the set value. Specifically, (i) if the reference parameter is based on the input pressure, the engine parameter and set value, the exhaust gas pressure is used; and (ii) if the reference parameter is based on the input pressure, the exhaust gas pressure and the engine parameter, the set value is used.
- the procedure is preferably executed repeatedly, or continuously, such that for examp- Ie while the step 460 operates on data registered at a particular instance t, the steps 410, 420, 430 and 440 operate on data registered at a somewhat later instance t + ⁇ t.
- All of the process steps, as well as any sub-sequence of steps, described with reference to the figure 4 above may be controlled by means of a programmed computer apparatus.
- the embodiments of the invention described above with reference to the drawings comprise computer apparatus and processes performed in computer apparatus, the invention thus also extends to computer programs, particularly computer pro- grams on or in a carrier, adapted for putting the invention into practice.
- the program may be in the form of source code; object code, a code intermediate source and object code such as in partially compiled form, or in any other form suitable for use in the implementation of the process according to the invention.
