Definitions

• the invention relates to a method for controlling a sailing operation of a comprehensive, a manual transmission vehicle, in which a clutch is automatically opened and closed during a journey of the vehicle, and an apparatus for performing the method.
• From DE 102 21 701 A1 discloses a control method for motor vehicles with automated clutch device is known, in which the motor vehicle is put into a sailing operation. Sailing is a deliberate disengagement in coasting phases to understand in which neither the accelerator pedal as Kraftstoffzubuchbeiersglied nor the brake pedal is actuated.
• This sailing mode essentially serves to save fuel.
• the clutch is opened under control by the electronic control unit when the gear is engaged, so that the vehicle rolls without losing kinetic energy due to the braking effect of the engine.
• the sailing mode is usually terminated by operation of a brake or the accelerator pedal.
• the disadvantage here is that it is also decided at the same time with the sail once set whether the vehicle driving the engine continues to run or is turned off. That is, with the decision on the sailing mode, only the entire sailing functionality can be activated or deactivated.
• the invention has for its object to provide a method for controlling a sailing operation of a vehicle, in which no longer is determined from the outset, whether the sailing should be done with activated or deactivated internal combustion engine.
• the object is achieved in that the sailing operation is varied depending on a current driving condition of the vehicle. It can be made possible a variety of combinations that decide once whether sailing is allowed at all or during a sailing operation, the internal combustion engine is activated or deactivated. It should be further below the current Driving state a parameter range of various parameters of the vehicle are understood, which is set variably within parameter limits.
• the parameter limits which are considered in the current vehicle state, give conclusions about the driving situation and can be detected on the basis of eg an accelerator pedal position, a brake pedal position or a steering angle.
• the sailing operation is varied as a function of at least one vehicle-specific parameter.
• a vehicle-specific parameter can be understood, for example, as the battery state of charge or an engine speed.
• the sailing operation is started or terminated depending on the current driving state of the vehicle and / or the at least one vehicle-specific parameter.
• the current driving state and the at least one vehicle-specific parameter represent different classes of input signals or input parameters, the evaluation of which can be used for a combination state during sailing operation.
• an internal combustion engine is switched off and / or on again during sailing operation as a function of the current driving state of the vehicle and / or of the at least one vehicle-specific parameter.
• the operating state of the internal combustion engine can be varied during the sailing operation, so that it is not necessary to determine from the outset when calling up the sailing operation in which operating state the internal combustion engine is located.
• the internal combustion engine is operated during the entire sailing operation. But there is also the possibility that the internal combustion engine is completely switched off during the entire sailing operation. This decision is made depending on the driving condition and / or the at least one vehicle-specific parameter and regardless of the decision whether a sailing operation is set or not.
• a development of the invention relates to a device for controlling a sailing operation of a comprehensive, a manual transmission vehicle, which controls a arranged in the transmission clutch for opening and closing while driving the vehicle.
• a device in which there are many possible combinations during the control of the sailing operation is at least one logic unit having at least one first sensor unit for outputting a vehicle-specific parameter and / or connected to a second sensor unit for displaying a current driving state of the vehicle for setting the sail operation.
• sailing operation starting sail start logic unit is connected to a motor logic unit for deciding on the operation of an internal combustion engine during sailing operation, wherein the engine logic unit is connected to the first and / or the second sensor unit.
• these two logic units evaluate the input signals independently and determine different driving situations during sailing operation. These driving situations include “no sailing with engine ON”, “no sailing with engine OFF”, “sailing with engine ON” and “sailing with engine OFF”.
• a sail end logic unit connected to the first and / or the second sensor unit terminates the sail operation as a function of the input signals. This decision is made independently of the other logic units.
• Fig. 2 shows an embodiment of the method according to the invention.
• a control unit 1 which represents an embodiment of the device according to the invention.
• the control unit 1 is designed as an engine control unit, but may alternatively be a separate control unit, which controls a sailing operation in a, formed with a manual transmission vehicle.
• the vehicle with manual transmission thereby has a clutch actuator, which can optionally open the clutch parallel to the clutch pedal or has the sole control of the clutch operation.
• the clutch actuator can receive signals via one or more sensors, which determine the position of the clutch pedal on the pedal itself or on the master cylinder of the release system or on other Re sense the intention of the driver to operate the clutch by means of the clutch pedal.
• sailing is to be understood below as meaning the automated opening of the clutch, in particular during the drive of the vehicle, the additional option being to switch off the internal combustion engine in the sailing phases.
• the aim of the curse is to decouple the internal combustion engine from the drive train, in order to avoid its drag torque as loss torque, which can lead to fuel savings.
• the vehicle with manual transmission can be an automated
• Clutch actuator which is connected in parallel with a clutch pedal.
• the use of an electronic clutch management or a clutch-by-wire clutch is also possible.
• the control strategy for the sailing operation stored in the control unit 1 globally regulates the opening and closing of the clutch independently of driver actuations and the disconnection or adjustment of an internal combustion engine driving the vehicle.
• the control unit 1 comprises three logic units 2, 3, 4.
• the first logic unit is a sail start logic unit 2, which is connected to a motor logic unit 3. Parallel to the sail start logic unit 2, a sail end log unit 4 is present, which decides on the switching off of the sailing process. All three logic units 2, 3, 4 are independently the same input signals available by each logic unit 2, 3, 4 is directly connected to a first sensor unit 5 for outputting a vehicle-specific parameter and with a second sensor unit 6 for displaying the driving condition of the vehicle.
• FIG. 1 An embodiment of the method according to the invention is shown in FIG.
• the input signals are provided by the first sensor unit 5, which are characterized by the vehicle-specific parameters.
• further input signals are provided by the second sensor unit 6, which characterize the vehicle condition.
• These inputs are passed to block 103, where the input signals are evaluated and decided on sail entry.
• the sail entry of the vehicle is triggered in the case of a positive decision.
• the input signals 101 and 102 lead directly to a block 109, which decides whether the sailing operation is aborted. If the decision is made that the sailing operation is terminated, in block 1 10 of the termination of the sailing operation, in which preferably the clutch of the vehicle is closed again.
• Each state is triggered via the corresponding logic unit 2, 3, 4 independently of the others.
• a sailing strategy depending on the current driving situation of the vehicle.
