Definitions
- the invention relates to an electronic-hydraulic control device of an automatically switching motor vehicle transmission, in which friction clutches or brakes, which can be engaged and disengaged hydraulically, are actuated for shifting individual gear stages, as a function of operating parameters of the motor vehicle transmission and a drive motor, as well as devices for Switching and / or driving program influencing the actuating devices are pressurized by the electronic-hydraulic control device.
- An electronic-hydraulic control device of an automatically switching motor vehicle transmission of the aforementioned type is known from EP 0 440 748 Bl.
- a control valve is assigned to each actuating device, and the solenoid valves and switching valves, which are used to control the control valves, can perform multiple functions.
- the control unit of this transmission control has a device for fault monitoring, an assigned solenoid valve or pressure control valve being reversed when the fault signal occurs in such a way that the motor vehicle transmission is idling at least in phases. For a motor vehicle, it is necessary to be able to continue driving even if the electronic control is defective.
- the invention has for its object to provide an electronic-hydraulic transmission control for a transmission with automatic gear change, preferably a six gear, to create, in which the clutches or brakes of the transmission can be controlled by an electronic control unit and in the event of failure of the electronic control unit, an emergency gear is automatically switched, which is designed such that when driving in the upper
- Transmission gears (four to six) are shifted into an upper gear in the event of a fault and into a lower gear when driving in the lower gears (one to three) in the event of a fault.
- the clutch or brake which must be switched for the emergency gear, is not acted upon by a regulated pressure but by the full system pressure when the emergency occurs.
- the gear jump from the gear previously operated to the emergency gear must not be too great.
- the control valves are switched so that in a previously driven upper gear preferably fourth to sixth gear, in an upper gear preferably fifth gear and when driving in the lower gears, preferably gears one to three, in a lower gear Gear, preferably the third gear, is switched.
- the reverse gear can be engaged in emergency mode directly by moving the selector slide.
- the vehicle e.g. B. in a braking process at a traffic light
- the control valves switch over in such a way that when the internal combustion engine is started again, the third gear is automatically switched if the electronic control unit is defective. Since this electronic-hydraulic transmission control is preferably used for a six-speed automatic transmission, the control valves which control the clutches and brakes are designed in such a way that they have two different valve characteristics.
- a clutch is both z. B. operated in third and fifth gear to engage the gears.
- the torque on the clutch in a lower gear has a difference to the torque of the same clutch in upper gear, it is necessary to apply different pressures to the actuating device of this clutch depending on the gear engaged.
- the Control valves are either pressurized only from one surface or, if a second valve characteristic is required, the control valves are pressurized from another surface, the surface of the one pressurized side being different from the other surface.
- 1 is a transmission diagram of a six-speed
- Fig. 3 is a simplified control scheme of the control device according to the invention.
- Fig. 4 is a table in which the switched solenoid and electrical pressure control valves are shown for each switched gear.
- the illustrated transmission diagram shows a six-speed transmission in planetary design, in which the drive shaft 1 is driven by an internal combustion engine, not shown.
- the drive shaft 1 can be connected to the output shaft 2 via the clutches A, B, E and brakes C, D.
- the shifted clutches or brakes to the corresponding gears are shown in Fig. 2.
- a pump 3 is driven by an internal combustion engine, not shown, which supplies the system pressure for the electro-hydraulic transmission control.
- the system pressure is regulated by the system pressure valve 4. If the selector slide is moved into a forward travel position, the electrical pressure control valves 6, 7, 8, 9, 10, 11 and solenoid valves 12, as can be seen in the table in FIG. 4, are activated, depending on the parameters of the internal combustion engine and the automatic transmission. Is z. B. the second gear is engaged, the pump 3 supplies the control with pressure medium via a channel 13, which is controlled by the system pressure valve to a predetermined level. The reversing valve 15 is reversed via the channel 14, thereby connecting the channel 16 to the channel 17.
- the electronic control unit checks whether the gear selection is permissible and then controls the electrical pressure control valves 6, 8 and 11. In this state, the emergency drive valve 18 and the switching valve 19 are in the starting position. The control valve 20 is reversed and the clutch A is closed. The control valve 21 is reversed and the brake C is closed. The second gear is thus engaged. If a fault occurs in the electronic control unit in gears one to three, the solenoid valves 12 and the electrical pressure control valves 6, 7, 8, 9, 10, 11 are switched off. Since the pressure control valve 7 is without current, the electrical pressure control valve 7 is reversed by its spring in such a way that the control valve 23 is reversed via the channel 22. is controlled and clutch B closes unregulated.
- the channel 17 is connected to the channel 16 and the pressure which acts on the actuating device of the clutch B is passed to the control valve 20 via the emergency drive valve 18.
- the control valve 20 is thus pressurized so that the clutch A remains closed.
- the valve 24 is reversed via the channel 16 and the channel 25 is pressurized.
- the switching valve 19 is reversed so that the connection from the channel 26 to the channel 27 is changed over and thus the channel 28 is depressurized, as a result of which the control valve 29 reverses and the clutch D is released without pressure.
- the electrical pressure control valves 6, 7, 8, 9, 10, 11 and the solenoid valves 12 are also de-energized. As described above, the electrical pressure control valve 7 is reversed via its spring and thus the clutch B is closed. With the upper gears 4, 5 and 6 engaged, the solenoid valve 12 is energized during normal operation of the electronic control unit. For this reason, the emergency drive valve 18 is still moved against its spring when the error occurs in the electronic control unit.
- the system pressure must be interrupted for a short time, which can be done by switching off the internal combustion engine or by manually switching another valve.
- the emergency drive valve 18 goes into its initial position and when the engine is restarted and the driving position is engaged, third gear is now automatically engaged again.
- control valves which are assigned to the clutches and brakes, can be pressurized from both sides, but they have different surfaces on the two sides, so it is possible, on the one hand, to pressurize a surface with a first valve characteristic and on the other hand to realize a second valve characteristic by pressurizing a second surface and a first surface.
- This is necessary because certain clutches or brakes are used in several gears, e.g. B. clutch C is applied in gears two and six.
