Definitions
- the invention relates to a method and system for controlling the creep behavior of a vehicle equipped with an automated clutch.
- FIG. 5 shows an exemplary block diagram of a drive train of a motor vehicle equipped with an automated clutch.
- the drive train contains an internal combustion engine 2, a clutch 4 and a transmission 6, from which a drive shaft 8 leads to drive wheels, not shown.
- the transmission 6 is, for example, an automated manual transmission, a conical pulley belt transmission with continuously variable transmission ratio or a conventional automatic transmission working with planetary gears.
- An actuating device 9 is used to actuate or shift the transmission 6, which is operated from a selector device 10 by means of a selector lever 12 can be controlled via a control device 14 in a manner known per se. It goes without saying that the selection device can also be designed differently, for example as a classic shift lever (H-link) or as a lever with tip positions for shifting up and down.
- the clutch 4 is, for example, a friction disk clutch of a type known per se with an actuating device 16 which is designed hydraulically, electrically, electrohydraulically or in some other known manner.
- Sensors contained in the drive train such as a pressure sensor 18 for detecting the intake pressure of the engine 2, a speed sensor 20 for detecting the speed M of the crankshaft of the engine, a sensor 22 for detecting the position ⁇ of an accelerator pedal 24, and a sensor 26 for detecting the position of the Selector lever 12 and a further speed sensor 28 for detecting the speed of the drive shaft 8 are connected to the inputs of the control unit 14.
- the control unit 14 which contains a microprocessor with associated memories 29 in a manner known per se, characteristic maps and programs are stored with which actuators, such as a load actuator 30 for adjusting the load of the motor 2, the actuating device
- the individual actuators can be constructed in such a way that their position is known directly in the control unit 14, for example as stepper motors, or additional position transmitters, such as a position
- a brake pedal 34 is connected via a hydraulic line 35 to a brake pressure control device 36, which is connected to the vehicle brakes 38 via further hydraulic lines
- a further electronic control device 40 is provided, which is connected to the control device 14 via a data line 42.
- the pressure generated in the hydraulic line 35 by actuation of the brake pedal 34 is detected by a pressure sensor 44 connected to the control unit 14.
- the control device 40 controls the brakes, for example, in a manner known per se, in such a way that a
- the load actuator 30, the actuating device 16 and the actuating device 9 are actuated in a mutually coordinated manner as a function of signals supplied by the sensors, so that there is comfortable and / or economical driving.
- a characteristic curve is stored in a memory of the control unit 14, which defines a set position of the clutch 4 set by the actuating device 16 as a function of the torque to be transmitted by the clutch 4 in each case.
- the clutch torque that can be transmitted should only be as large as is absolutely necessary.
- the required torque to be transmitted results from the driver's request or the position of the accelerator pedal 24 and, for example, the load of the internal combustion engine 2 detected by the sensor 18 and possibly further operating parameters, such as the speed of the engine 2 etc.
- the characteristic curve stored in the control unit 14, which specifies the desired path of an actuator of the clutch moved by the actuating device 16 as a function of the calculated torque to be transmitted, has a decisive influence on comfortable starting and a comfortable handling of the switching process.
- the characteristic curve changes briefly, for example as a result of temperature changes, and long-term in the course of the life of the clutch, for example as a result of wear. It is therefore constantly updated or adjusted according to various strategies when predetermined operating conditions are present.
- This creep torque is regulated, for example, by the control device 14 slowly closing the clutch 4 with the aid of the actuating device 16 when the drive is engaged and the accelerator pedal is not actuated, and the engine is controlled by controlling the load actuator 30 of the internal combustion engine 2 while maintaining the engine 2 as constant as possible is controlled such that it generates the predetermined torque on the clutch. It goes without saying that the Power consumption of any other consumers driven by the engine is taken into account.
- a peculiarity of the known creep behavior of vehicles lies in the fact that the driver cannot directly influence the creep behavior, which, for example when maneuvering on sloping roads, leads to impaired comfort and requires a high level of skill on the part of the driver.
- the invention has for its object to provide a method and a system for controlling the creep behavior of a vehicle equipped with an automated clutch, with which a further increase in comfort of the creep behavior is possible.
- the driver can directly influence the position of the clutch and thus the creep by actuating the brake, so that the creeping torque which the clutch transmits during creep conditions can vary within wide limits. Furthermore, the clutch is protected because the creep torque is weakened with increasing brake application and the clutch or the motor does not work fully against the brakes.
- Fig. 1 is a flow chart for explaining a creep strategy
- Fig. 2 shows the previously described scheme of a known vehicle drive train with control.
- the KP creep parameter is a quantity that indicates the "creep strength" of the vehicle.
- the function f is such that KP S decreases with increasing brake application B, that is, when the brake is not applied, the vehicle creeps strongly on its own and with increasing brake application the creep strength weakens, for example by increasingly opening the clutch or the Motor is controlled so that its torque is reduced.
- the measure of the brake actuation B can be given, for example, by the pressure p detected by the sensor 44 or by a force with which the brake pedal is actuated or the path by which the brake pedal is deflected (corresponding sensors are not shown).
- the force on the brake pedal or the way of actuation Taking the brake pedal as the characteristic characterizing the brake actuation is advantageous in electronic or electrical brake systems in which, like in electronic accelerator pedals, the actuation of the brake itself is decoupled from the actuation of the brake pedal.
- the actuation of a Hans brake lever, not shown, can also be used as the characteristic quantity for the brake actuation.
- the creep parameters determining the creep behavior of the vehicle can be of the most varied types.
- the creep torque transmitted by the clutch 4 can be used as a creep parameter, the engine then being kept at a constant speed, for example with an idle speed control device (not shown), and the clutch being controlled by the actuating device 16 in such a way that the torque predetermined by the brake actuation is controlled by it is transmitted.
- the torque that is transmitted when there is no brake actuation can be set so high that the vehicle, for example, also creeps forward when it is uphill.
- the vehicle speed is used as the creep parameter, which, in order to be sufficiently precisely measurable even at very low speeds, is advantageously detected by a sensor that detects the rotation of an input shaft of the transmission 6, which with known translation of the Transmission can be converted directly into the vehicle speed.
- the speed sensor 28, which detects the speed of the output shaft 8 of the transmission in FIG. 2 can then be omitted and is replaced by a corresponding sensor which detects the speed of the input shaft of the transmission 6. Because of the higher rotational speed of the transmission input shaft compared to the rotational speed of the wheels of the vehicle, it is favorable to detect the rotational speed of the transmission input shaft and not to use the wheel speed sensors which are generally present in vehicles with ABS systems.
- step 50 it is first determined whether the vehicle is in crawl mode or not.
- the creep mode is defined, for example, by the engine running, the accelerator pedal 24 not being operated and the forward gear with the highest gear ratio or the reverse gear engaged.
- step 52 If the vehicle is in creep mode, it is determined in step 52 whether the clutch 4 or the motor 2 are controlled in such a way that the instantaneous creep parameter KPj is greater than that, for example, of the actuation of the brake pedal 34 (for example that recorded by the sensor 44 Pressure) dependent target creep parameters KP S plus a value ⁇ which is advantageous for control reasons, ie whether the condition is fulfilled:
- step 54 the clutch is increasingly opened and / or the engine torque is weakened in step 54, so that KPj is reduced, for example, by a predetermined amount.
- the system then jumps to step 50 again.
- step 54 If it is determined in step 52 that the condition is not fulfilled, then it is determined in step 54 whether the condition KPj ⁇ KP S - ⁇ . If this is the case, KPj is increased in step 56 and the system jumps to step 50. If it is determined in step 54 that the condition checked there is not fulfilled, then the motor and / or the clutch is activated in step 58 maintained, whereupon the system jumps to step 15. If it is determined in step 50 that the creep mode is no longer present, for example by accelerating, engaging neutral gear or, for example, pressing the brake pedal with a force that is above a threshold value, the system jumps to termination step 60, in which crawl mode is ended.
- V max is the maximum creep speed (if the brake is not applied). If the brake actuation B exceeds the value B max , the creep speed should be reduced to zero.
- the torque transmitted via the clutch is regulated by the control unit 14 in such a way that the desired speed which is dependent on the brake actuation is set quickly and without control oscillations. In this way, the vehicle shows a creep behavior with which it can be maneuvered extremely comfortably under the most varied of conditions.
- the strategy can also be used on the mountain if the engine is able to provide sufficient torque within the controlled range, for example at its idling speed. Otherwise, the control range of the engine can be expanded by not only activating the idle speed control system, but also changing the position of a load actuator.
- the described method according to the invention can be modified in many ways. For example, different characteristic curves, setpoints and limit values can be used for a forward and a reverse gear stage.
