- a power source for example, an engine throttle opening, a fuel injection amount, an ignition timing, and the like are controlled based on the determined target acceleration.
- a power source is controlled based on a target acceleration or a target driving force, which is a required value corresponding to the acceleration generated in the vehicle, but also an acceleration corresponding to the required value is achieved.
- the automatic transmission is also controlled based on the required value. Also in the vehicle control system that performs such torque demand control, as shown in Patent Document 2, not only automatic shift control for automatically shifting the automatic transmission, but also the automatic transmission is manually shifted by the operation of the driver. Manual shift control can be performed.
- the torque demand control is intended to achieve the feeling of acceleration required by the driver, which is required from the driver's accelerator operation, regardless of the current gear position.
- manual shift control the automatic transmission is shifted according to the driver's intention, and the object is to obtain an acceleration feeling corresponding to the driver's accelerator operation that differs for each shift stage. That is, the manual shift control is a driver's request to improve the controllability of the vehicle by manually shifting the automatic transmission. Therefore, if the vehicle generates the same acceleration as in the automatic shift control during the manual shift control in the torque demand control, the vehicle may not meet the driver's request.

- the switching operation may be performed by changing the control amount from the pre-switching control amount that is the control amount at the time of control before the control switching to the post-switching control amount that is the control amount at the time of control after the control switching. It is preferable that the control amount change be more gradual when the accelerator is on than when it is off.

To is calculated.
- the target engine torque calculation unit 74 for example, the target driving force Fo calculated at the time of manual shift control or the target engine torque To calculated based on the target driving force Fo is changed according to the actual shift speed nr. Correction is made so that the change in the acceleration G generated in CA becomes larger than that in the automatic shift control.

- the maximum acceleration Ga max during the automatic shift control does not change regardless of the shift of the automatic transmission 61.
- the maximum acceleration Gm max during the manual shift control changes due to the shift of the automatic transmission 61.
- the acceleration G generated on the vehicle CA is between the accelerator is fully closed to fully open throttle, changes minimum acceleration Ga mim, the Gm mim maximum acceleration Ga max, until Gm max. Accordingly, the width of the acceleration G corresponding to the driver's accelerator operation during the automatic shift control does not change at an arbitrary vehicle speed v (La shown in the figure).
- the width of the acceleration G corresponding to the driver's accelerator operation during the manual shift control changes according to the shift stage at an arbitrary vehicle speed v (Lm n , Lm n-1 shown in the figure). That is, at the time of manual shift control, the acceleration G generated in the vehicle CA changes for each shift stage with the accelerator opening Pa and the vehicle speed v being the same.

- the pre-switching control amount is a control amount at the time of control before the control switching instruction, and in the embodiment, is determined in the control before the control switching (automatic shift control or manual shift control) by the control switching instruction. This refers to the pre-switching torque Toa that is the target engine torque To.
- the control amount after switching is a control amount at the time of control after the control switching instruction.

- the switching operation control unit 75 for example, the current accelerator opening Pa, the instruction accelerator opening Pa1, the predetermined accelerator opening Pax, the pre-switching torque To1, the post-switching torque Tox, and the following equation (1)
- the target engine torque To during the switching operation is calculated, and the engine 5 is controlled based on the calculated target engine torque To.
- the predetermined accelerator opening degree Pax is determined based on the instructed accelerator opening degree Pa1, and when the accelerator opening degree Pa increases due to the driver's accelerator operation, and when the accelerator opening degree Pa decreases. Therefore, it can be set to either plus or minus.

Therefore, when the control switching is performed from the automatic transmission control to the manual transmission control immediately after the control switching instruction, the driving force F changes according to the change in the target engine torque To, and the accelerator opening Pa is constant and the automatic transmission.
- the gear 61 is not shifting, a shock may occur in the vehicle CA, which may cause the driver to feel uncomfortable.

Therefore, for example, when the accelerator opening degree Pa further increases from the predetermined accelerator opening degree Pax, the engine 5 is controlled based on the target engine torque To in the case of the accelerator opening degree Pa at the time of manual shift control.
- the switching operation control unit 75 gradually changes the target engine torque To from the pre-switching torque to the post-switching torque while the accelerator opening degree Pa is changing, that is, while the driving force F is changing. Therefore, since the control switching can be performed while the acceleration G generated in the vehicle CA is changing, in a state where the accelerator opening degree Pa does not change, that is, in a state where no step is generated in the driving force F for the driver. The occurrence of a shock or the like due to control switching can be suppressed, and the driver can be prevented from feeling uncomfortable. Note that the switching operation control unit 75 performs the same switching operation as described above even when the control switching is performed from the manual shift control to the automatic shift control.
- the switching operation control unit 75 performs a switching operation in which the target engine torque To is set to the post-switching torque To immediately after the control switching instruction when the accelerator is off at the time of the control switching instruction, that is, the accelerator opening degree Pa is 0%. That is, the switching operation control unit 75 immediately switches control based on the control switching instruction if the accelerator is off at the time of the control switching instruction. For example, when control switching is performed from manual shift control to automatic shift control, if the accelerator is off at the time of control switching instruction, the switching operation ends immediately after the control switching instruction, and at the time of control switching instruction at the time of manual shift control The target engine torque To in the case of the accelerator opening degree Pa is calculated, and the engine 5 is controlled based on the calculated target engine torque To.

In other words, the switching operation control unit 75 immediately switches control based on the control switching instruction when the accelerator is on at the time of the control switching instruction and the automatic transmission 61 is shifted after the control switching instruction.
- the switching operation control unit 75 keeps the accelerator opening degree Pa at the instructed accelerator opening degree Pa2, and changes the shift stage of the automatic transmission 61 from the n-th speed to the (n ⁇ 1) based on the shift instruction by the driver operating the shift lever 43.
- shifting to a high speed that is, downshifting (t2 in the figure)
- the automatic shift control is immediately switched to the manual shift control, and at the time of the manual shift control, the shift stage is n-1 speed and the instructed accelerator opening Pa2.
- the engine 5 is controlled based on the target engine torque To3 in the case.
- the driver has a desire to change the driving force F and change the acceleration G. Therefore, when the driver seeks a change in the driving force F due to the shift of the automatic transmission 61, the driving force F can be changed to reflect the driver's will, which makes the driver feel uncomfortable. Can be suppressed.
- the switching operation control unit 75 changes the speed of the automatic transmission 61 from n-speed to n + 1-speed based on the shift instruction in the automatic shift control while the accelerator opening Pa remains the instruction-time accelerator opening Pa2. (T2 in the figure), the manual shift control is immediately switched to the automatic shift control, and the engine 5 is controlled based on the target engine torque To5 in the case of the command accelerator opening degree Pa2 during the automatic shift control.
- FIG. 7 is a control flowchart showing a vehicle control method by the vehicle control system according to the embodiment. Since the method for controlling the engine 5 and the automatic transmission 61 by the automatic shift control or the manual shift control has been described above, the description thereof is omitted here. Hereinafter, the control method of the switching operation is executed every predetermined control cycle. Moreover, the control flow shown in the figure is an example, and the order of each process is not limited.

- Step ST6 the switching operation control unit 75 determines that the accelerator opening degree Pa is 0 (Yes in Step ST2) or determines that the shift of the automatic transmission 61 is performed (Yes in Step ST4)
- the switching operation control unit 75 performs the control after the control switching. Control is executed (step ST6), the current control cycle is terminated, and the next control cycle is started. Therefore, the control is immediately switched immediately after the automatic transmission 61 is shifted.
- the target engine is set such that the change in the acceleration G generated in the vehicle CA due to the shift of the automatic transmission 61 is greater than that during the automatic shift control. Since the torque To is determined and the engine 5 is controlled based on the determined target engine torque To, it is possible to improve the controllability of the vehicle during manual shift control. In addition, since the switching operation for performing actual control switching is changed according to the accelerator operation after the control switching instruction, it is possible to suppress the driver from feeling uncomfortable.

That is, the target engine torque To at the time of manual shift control may be obtained by a conventional method for calculating the target engine torque To in the vehicle CA. In this case, during the automatic shift control, the target engine torque To is calculated so that the change in the acceleration G generated in the vehicle CA due to the shift of the automatic transmission 61 becomes smaller than during the manual shift control.
- the automatic transmission 61 may be forcibly changed when the control is switched.

- the switching operation control unit 75 performs the switching operation while the accelerator opening degree Pa is changing when the accelerator is on. Accordingly, in the switching operation, the control shift from the automatic shift control to the manual shift control is not performed immediately after the control switch instruction, and the pre-switching torque To1 in the case of the command accelerator opening degree Pa1 is maintained during the automatic shift control.
- the target driving force Fo is used as the required value corresponding to the acceleration G generated in the vehicle CA, but the present invention is not limited to this and may be the target acceleration Gx.
- the target engine torque To and the target shift stage no are determined based on the target acceleration Gx.
