Abstract

A starting control method of a vehicle having an Automatic Manual Transmission (AMT), comprising: starting operation in braking, when ignition is turned on when the vehicle is braked, releasing the clutch and starting the engine through the controller; and an N-range changing operation of changing, by the controller, the shift range of the transmission to the N-range when a condition for performing the start operation in the braking is satisfied and the current shift range of the transmission is not the N-range.

Description

Start control method for vehicle with AMT
Technical Field
The present invention relates to a starting control method of a vehicle having an Automatic Manual Transmission (AMT), and more particularly, to a technique of starting the vehicle as much as a user's intention with respect to a vehicle starting operation by the user.
Background
Like a conventional Manual Transmission (MT), an Automatic Manual Transmission (AMT) performs shifting by selecting a speed change gear of a power transmission target as a synchromesh device among normally engaged speed change gears, in which case all intermittent operations of a clutch that selects gear selection and shifting of the speed change gear of the power transmission target are automatically performed by an actuator controlled by a controller, so that a driver can drive the vehicle as if driving a vehicle having the conventional automatic transmission.
At the time of vehicle start, in order to prevent an unexpected situation such as sudden acceleration, it is desirable to release all shift positions of the transmission and start the engine only when the driver depresses the brake pedal.
In general, in the case of the vehicle with the AMT described above, a neutral state of the transmission and a brake depression are also required as prerequisites for starting the engine to ensure the safety of the vehicle.
Therefore, in the case of a vehicle with an AMT, when the driver does not depress the brake pedal or the transmission gear of the transmission is engaged, i.e., in the D-range or the R-range, if the driver attempts to start the engine, the controller turns on a warning lamp on the dashboard or generates a warning sound to notify the driver that the current state is a state in which the engine cannot be started.
However, inexperienced drivers, hearing impaired persons, and the like cannot appropriately recognize or confuse the above-described warning.
The matters disclosed in this section are nothing but the ones used to facilitate an understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this matter forms the prior art known to a person skilled in the art.
Disclosure of Invention
An object of the present invention is to provide a starting control method of a vehicle having an Automatic Manual Transmission (AMT), in which the vehicle having the AMT can smoothly start an engine by reflecting a driver's intention to start the engine as much as possible while ensuring vehicle safety against sudden acceleration of the vehicle, so that unnecessary warnings can be minimized and the vehicle can be operated in a user-friendly manner, thereby improving marketability of the vehicle.
According to an embodiment of the present invention, a starting control method of a vehicle having an Automatic Manual Transmission (AMT) may include: starting operation in braking, when ignition is turned on when the vehicle is braked, releasing the clutch and starting the engine through the controller; and an N-range changing operation of changing, by the controller, the shift range of the transmission to the N-range when a condition for performing the start operation in the braking is satisfied and the current shift range of the transmission is not the N-range.
The method may further comprise: and a shift operator switching operation of switching the shift operator to the N range by the controller when the engine start is completed in the start-in-brake operation and the current shift range of the transmission is changed to the N range in the N range changing operation.
The method may further comprise: a manual manipulation guiding operation, when the starting operation in braking is completed, if the change to the N range fails during the N range changing operation, the driver is caused to attempt the manual change to the N range by the controller.
The method may further comprise: a clutch engagement suspension preparation operation of setting, by the controller, engagement of the suspension clutch when a start operation is completed in braking and a change to the N-range fails during the N-range changing operation, even if the clutch needs to be engaged before a manual manipulation guiding operation; and a clutch engagement suspension release operation of releasing the clutch engagement suspension preparation operation by the controller when the transmission is changed to the N range in the manual manipulation guiding operation.
When a manual manipulation of the guiding operation is attempted within a predetermined reference time and the transmission has not changed to the N range after the reference time elapses, the engine may be turned off.
The manual manipulation guide operation may be performed by outputting information indicating that the automatic change to the N range has failed and a warning for requesting a manual change to the N range to the driver.

Fig. 1 is a diagram showing the configuration of a vehicle with an Automatic Manual Transmission (AMT) to which the present invention is applicable.
Fig. 2 is a flowchart of a starting control method of a vehicle with an AMT according to the present invention.
Detailed Description
Fig. 1 is a diagram showing the configuration of a vehicle with an Automatic Manual Transmission (AMT) to which the present invention is applicable. The power of the engine E may be transmitted to the AMT through the clutch CL to perform shifting, and may be output to the drive wheels W on both sides through the differential DF.
A Transmission Control Unit (TCU) as a controller for controlling the AMT may be configured to control the AMT and the engine while communicating with an Engine Control Unit (ECU) as a controller for controlling the engine.
Specifically, the TCU may control the clutch actuator CA to manipulate the clutch CL, and may control the gear selection/shift actuator SA to perform a gear change by the gear selection and shift operation of the AMT.
The shift operator MP for receiving a driver's shift manipulation may be connected to the TCU, may be configured in the form of a shift lever as in the related art or may use various manners such as a push button type or a touch type, and may perform functions of enabling the driver to select a D range for forward running of the vehicle, an N range as a neutral state in which all shift ranges of the transmission are released, and an R range for reverse running of the vehicle.
The ECU may be a controller for controlling the engine and may communicate with the TCU to perform a function of starting the engine to control the engine when an engine start condition is satisfied.
Generally, the TCU and the ECU are independently installed in the vehicle, but may be theoretically or conceptually integrated with each other, and the ECU and the TCU need not be separately described in the following description of the present invention, so the term "controller" may collectively refer to the TCU and the ECU.
Referring to fig. 2, a starting control method of a vehicle having an AMT according to the present invention may include: a start-in-brake operation S10 of releasing the clutch CL and starting the engine E by the controller when the ignition is turned on at the time of braking of the vehicle; and an N-range changing operation S20 of changing, by the controller, the shift range of the transmission to the N range when the condition of performing the in-brake starting operation S10 is satisfied and the current shift range of the transmission is not the N range.
That is, according to the present invention, when the braking state of the vehicle is ensured, even if the shift range of the transmission is not the N range, the engine is first enabled to be started to minimize unnecessary warnings and to reflect the intention of the driver as much as possible to enable the engine to be started.
Needless to say, even if the engine is started in the above state, at least one brake device of the vehicle is operated to apply a braking force, and the engine is started in a state where the clutch CL is released as described above, so even if the shift range is the D range or the R range, the vehicle is not suddenly accelerated, and the safety of the vehicle can be ensured.
Needless to say, even if the safety of the vehicle is ensured as described above, the shift range can be automatically changed to the N range after the engine is started, and therefore the safety of the vehicle can be additionally ensured.
When the engine start is completed in the start-in-brake operation S10 and the current shift range change of the transmission to the N range is completed in the N range changing operation S20, the controller may further perform a shift operator switching operation S30 of switching the shift operator MP to the N range.
That is, when the transmission is changed to the N range in the N range changing operation S20, the shift operator MP is in a state where the D range or the R range other than the N range has been selected when the engine is started, and thus the selected range can be matched with the actual state of the transmission.
When the in-brake start operation S10 is completed, if the change to the N range fails during the N range change operation S20, the controller may further perform a manual manipulation guidance operation S50 of causing the driver to attempt a manual change to the N range.
That is, when the engine is started in the start-in-brake operation S10, but the state of the transmission is not automatically changed to the N range because the N range changing operation S20 is not appropriately performed due to a hardware problem or various other problems, the driver may be guided to attempt to manually change the transmission to the N range.
When the manual manipulation of the guiding operation S50 is attempted within a predetermined reference time and the transmission has not been changed to the N range after the reference time elapses, it may be desirable that the engine is turned off to ensure the safety of the vehicle.
Therefore, the reference time may be set in consideration of securing safety of the vehicle, and may be set in a range of several seconds to several tens of seconds, for example, 5 seconds or 10 seconds.
The manual manipulation guiding operation S50 may be performed by outputting information indicating that the automatic change to the N range has failed and a warning for requesting a manual change to the N range to the driver.
According to the present embodiment, when the in-brake cranking operation S10 is completed and the change to the N range fails during the N range change operation S20, the controller may further perform: a clutch engagement suspension preparatory operation S40 of setting the engagement of the suspension clutch CL even if the engagement of the clutch CL is required before the manual manipulation guiding operation S50; and an engagement suspension releasing operation S60 of a clutch engagement suspension preparation operation S40 when the transmission is changed to the N range in the manual manipulation guiding operation S50.
That is, when the in-brake cranking operation S10 is once completed to start the engine and the transmission is not automatically shifted to the N range, the clutch engagement suspension preparation operation S40 may be performed to prevent the clutch CL from being suddenly engaged to transmit the power of the engine to the drive wheels W.
Needless to say, even in the above state, if the state of the transmission is changed to the N range in the manual manipulation guiding operation S50, the engagement suspension releasing operation S60 may be performed, and if it is necessary to engage the clutch CL, the clutch CL may be allowed to be engaged.
As described above, according to the embodiments of the present invention, a vehicle having an AMT may reflect a driver's intention to start an engine as much as possible to smoothly start the engine while ensuring vehicle safety against sudden acceleration of the vehicle, and thus unnecessary warnings may be minimized and the vehicle may be operated in a user-friendly manner, thereby improving marketability of the vehicle.
The foregoing embodiments are therefore illustrative in all respects, and should not be construed as limiting. The scope of the invention is defined by the appended claims, rather than the description above, and all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
