- FIG. 3 shows an example of a schematic representation of the profiles of various operating parameters that can occur when driving down a motor vehicle with a known torque transmission device, an example change according to the invention being indicated schematically.
- FIG. 3 shows in particular the time profile of the actual clutch torque 300, the desired clutch torque 302, the transmission speed 304 and the engine speed 306.
- a clutch device is controlled by a control device, in particular by specifying a clutch setpoint torque 302 as a function of the transmission speed 304. If the gearbox speed 304 initially running synchronously with the engine speed 306, in particular when the vehicle rolls out on the mountain, to a predetermined value, which is shown here by way of example at about 1000 rpm, has dropped, the desired clutch torque is specified according to a changed characteristic. This is in particular designed in such a way that the desired engine torque 302 drops sharply, as the partial curve 308 of the desired clutch torque 302 illustrates.
- the target engine torque is controlled as a function of a constant value. This drop in the desired clutch torque means in particular that the clutch can now only transmit a reduced torque. This leads in particular to the fact that the gear speed 304 and the motor speed 306 diverge from point 310, so that slip occurs in the clutch.
- the transmission speed 304 Since the vehicle is accelerated by the downhill driving force and is braked to a lesser extent by the engine due to the at least partial opening of the clutch, the transmission speed 304 initially rises sharply in the region 312. At the same time, the engine speed 306 approaches the idle speed in the area 314. As soon as the increasing transmission speed 304 has reached a predetermined value, which is indicated schematically here at point 316, the desired clutch torque 302 is again specified in accordance with a changed characteristic, in particular a driving component flowing into the desired clutch torque 302 Increase in the desired clutch torque in the area 318, so that the clutch device closes increasingly.
- a predetermined value which is indicated schematically here at point 316
- This increasing closing of the clutch device has the effect, in particular, that the gradient of the time course of the transmission speed decreases, which is due in particular to the fact that the transmission speed is reduced as a result of the now more strongly braking engine.
- the gearbox speed 304 increases because it is accelerated more strongly due to the downhill force than it is decelerated due to the closing clutch. Then, however, falls also the gearbox speed 304.
- the engine speed 306 increases increasingly at a certain point, so that from point 318 the engine speed and the transmission speed run essentially synchronously again.
- FIG. 4 shows the time course of the transmission speed ( ⁇ ) 304 and the engine speed (n ⁇ ) 306 in an exemplary time course that can occur in a known arrangement when driving downhill.
- the engine speed 306 first falls in synchronism with the transmission speed 304.
- the clutch is increasingly opened so that the engine speed 306 approaches the idle speed 332.
- the transmission speed 304 initially increases because the vehicle accelerates due to the downhill force and because of the increasingly opening clutch device, the engine is no longer or less braked.
- Closing also increasingly brakes the engine of the vehicle, so that the gradient of the time course of the transmission speed decreases, then becomes negative, the engine speed 306 increasing due to the closing clutch, and then converges with the engine speed 306 at point 334, so that the Gearbox speed 304 and engine speed 306 run synchronously.
- the motor is further braked by the engine, so that the synchronously running speeds 304, 306 decrease and drop again to the disengagement curve 330.
- the speeds 304, 306 diverge again.
- the control device controls the clutch device according to a modified characteristic, so that the gradient of the time speed curve decreases, the speeds 304, 306 converge again, run synchronously, and again reach the decoupling shaft. In the worst case, this cycle can be repeated many times.
- FIG. 5 shows an example of a schematic representation of the curves of the engine speed 306 and the gear speed 304 during a downhill run, in which a control device controls the torque transmission device, in particular the clutch device, according to the invention.
- the characteristic for controlling the torque transmission device, in particular for controlling the transmission device is changed, in particular changed in such a way that the disengagement threshold is reduced, which is shown in FIG. 5 by arrow 342 pointing from point 330 to point 340 is indicated.
- the clutch device therefore opens, especially when rolling out on a mountain, only when the gear speed has reached the reduced disengagement threshold 340.
- the disengagement threshold 340 is preferably above the idle speed 332.
- the differential speed between the idle speed 332 and the disengagement threshold 340 is preferably dependent on the principle on which the drive device is based.
- the disengagement threshold 340 is between 0 rpm and 100 rpm above the idle speed 332. It is particularly preferred that the disengagement threshold is between 0 rpm and 50 rpm, for example at 40 rpm or at 0 rpm above the idle speed 332.
- the disengagement threshold is between 100 and 250 rpm above the idle speed 332.
- the clutch table shaft 340 is 150 rpm in gasoline engines.
- the transmission speed and the engine speed run synchronously over a longer period of time. It is particularly preferred that the disengagement threshold 340 is set in such a way that the speed at which the vehicle is moved settles to a substantially low speed.
- the engine braking force is essentially significantly greater than the specified braking force, so that the speeds 304, 306 decrease significantly.
- the speed 304, 306 is set to a value just above the disengagement threshold 340 A cyclical behavior of engagement and disengagement processes, as occurs in known arrangements, is thus avoided according to the invention.
