Abstract

PROBLEM TO BE SOLVED: To ease uncomfortable feeling that a driver feels when performing a gear shift control by a navigation cooperative shift control during traveling of a vehicle. SOLUTION: While the navigation cooperative shift control is executed (step S10) in an automatic transmission control device performing a traveling state shift control and the navigation cooperative shift control for an automatic transmission based on a traveling state of the vehicle, a speed gear stage and a road state are displayed by using an LCD (step S12). By this display, the driver can know why the gear shift control is performed and can predict the gear shift control to some degrees and thereby uncomfortable feeling that the driver feels due to a change of the speed gear stage can be eased.

Next, embodiments of the present invention will be described with reference to examples. FIG. 1 is a configuration diagram schematically showing the configuration of an automatic transmission control device according to one embodiment of the present invention. The automatic transmission control device 100 receives an A / T electronic control unit (A / TECU) 12 that controls an automatic transmission (A / T) 10 that is a multi-stage transmission, and shift control information from the A / TECU 12. LCD (Li
LCD electronic control unit (LCDECU) 16 for controlling a quid crystal display (14), and a current position detecting unit 3
A navigation electronic control unit (navi ECU) 34 for performing a route search process using the current position of the vehicle detected at 0 and map data stored in advance in the map data storage unit 32.
And a navigation system 36 having

The A / TECU 12 controls the A / T 10 based on the running state of the vehicle determined based on the vehicle speed detected by the vehicle speed sensor 20 and the throttle opening detected by the throttle opening sensor 22. Calculated based on the road information and the current position of the vehicle.
The navigation cooperative shift control for controlling the A / T 10 so that the gear is different from the traveling state gear control based on the optimum gear position information output from the control unit 4 is performed. A from navigation ECU 34
The / TECU 12 also outputs road conditions such as a flat road, a mountain road, a curve, an uphill road, and a downhill road in addition to the optimum gear position information. In addition, the road conditions of flat road, uphill road, downhill road,
The A / TECU 12 can also calculate from the information of the vehicle speed sensor 20 and the throttle opening sensor 22.

The LCD ECU 16 controls the type of control performed by the A / TECU 12 (running state shift control or navigation cooperative shift control), the current gear position of the A / T 10, and navigation cooperative shift control. The information of the road condition at the time of the input is input from the A / TECU 12, and control for displaying the information on the LCD 14 is performed. FIG.
FIG. 4 is a flowchart showing an example of a display processing routine performed by the DECU 16, and FIGS. 3 and 4 are display examples of the LCD 14. First, it is determined whether or not the control performed by the A / TECU 12 is the navigation cooperative shift control (step S10). If it is not navigation cooperative shift control, LC
The processing routine ends without displaying the message on D14.

In the case of navigation cooperative shift control, for example,
When the road condition is an uphill road or a downhill road, the characters "GEAR POSITION 3" representing the current gear position and the characters "SLOPE" representing the uphill or downhill road are displayed on the LCD 14 (step S12, FIG. 3), end the processing routine.

It should be noted that instead of the character "SLOPE" indicating the road condition, "NAVI (registered trademark) -E" indicating that the navigation cooperative shift control is performed as shown in FIG.
The character “CT” may be displayed on the LCD 14.

As described above, the automatic transmission control device 1
00 indicates that the A / T 10 is executing the navigation cooperative shift control, the gear position of the A / T 10, and the road condition can be displayed on the LCD 14. , And the shift control performed by the A / TECU 12 can be predicted to some extent, so that the uncomfortable feeling felt by the driver due to the change in the shift speed can be reduced.

In the automatic transmission control device 100 of the embodiment, the LCD 14 determines whether the road condition is an uphill road or a downhill road.
However, the present invention is not limited to this road condition, and may be displayed when the road condition is a curve, a flat road, a mountain road, or the like.

Further, in the automatic transmission control device 100 of the embodiment, the LCD 14 can display that the A / T 10 is executing the navigation cooperative shift control, the gear position of the A / T 10 and the road condition. May be selected and displayed as needed.
