Embodiment 1

[0028] figure 1 It is a figure explaining the schematic structure of the drive device 12 with which the vehicle 10 to which this invention is applied, and is a figure explaining the main part of the control system used for various control in the vehicle 10. exist figure 1 Among them, the driving device 12 includes an engine 14 as a power source, an automatic transmission 16 connected directly to the engine 14 or indirectly through a shock absorber not shown in the figure, and a differential gear device 18 connected to an output rotating member of the automatic transmission 16. , and a pair of axle shafts 20 connected to the differential gear unit 18, and the like. In the driving device 12, the power output from the engine 14 (torque and force mean the same unless otherwise specified) is transmitted to the automatic transmission 16, and is transmitted from the automatic transmission 16 via the differential gear device 18 and the like. It is transmitted to the drive wheels 22 ...

Embodiment 2

[0064] In this embodiment, a case in which the vehicle is traveling using the sport mode shift line is exemplified, and a specific mode of the control for selecting the above shift line will be described. The sports mode vehicle shift cable is the first power shift cable used when power performance is more important than fuel economy performance among various vehicle shift cables.

[0065] The vehicle state determination unit 60 determines whether the frequency of the acceleration request is high. Specifically, the vehicle state determination unit 60 determines whether or not the number of accelerations in a state in which the throttle opening tap is larger than a predetermined value is a predetermined number or more in the latest predetermined period. The above-mentioned predetermined value, predetermined period, and predetermined number of times are predetermined threshold values ​​for determining that the frequency of the acceleration request is high. The vehicle state det...

Abstract

The invention relates to a vehicle control apparatus, which can carry out speed change, which meets the traffic rules and intention of drivers, of automatic gearbox. The information based on the valueindicating the acceleration request reflecting the driver's intention or satisfaction, and the current information of the vehicle (10) reflecting the number of other vehicles (110) or driving tendency different for each area (Area) The information at the location distinguishes between the vehicle shifting line that is suitable for the vehicle (10) (for example, reflecting the difference in acceleration requirements), although the information of other vehicles (110) is not reflected, and the information transmitted by other vehicles (110) reflects each different center shift lines for each area (Area). Thereby, the shift of the automatic transmission (16) in accordance with the traveling road and the intention of the driver can be realized.

Description

technical field [0001] The present invention relates to a control device for a vehicle that performs shifting of an automatic transmission using information received from a device outside the vehicle. Background technique [0002] There is known a vehicle control device that performs shifting of an automatic transmission using information received from a device outside the vehicle. For example, the vehicle control device described in Patent Document 1 is such a vehicle control device. This patent document 1 discloses that a running environment of a vehicle is assumed based on information received from an external device, a shift characteristic corresponding to the traveling environment is set, and an automatic transmission is shifted using the shift characteristic. [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 11-315734 [0004] Then, it is conceivable to receive from the external device the information of the shift line that is different for each r...
