It is known that it begins to However, during the above-mentioned idling operation, if the engine speed is high due to application of a load such as an air conditioner or depression of the accelerator pedal, there is a possibility that the vehicle will start suddenly at the same time as the shift lever is switched. There is,
Japanese Utility Model Publication No. 60-23427 proposes a system that makes it impossible to shift from neutral to drive range when the brake is not activated and the engine speed is high.

る。The above-mentioned brake device IO is configured as a disc brake device in this embodiment, and the disc pads 13 and 14 facing each other with the brake disc 12 in between are connected to the caliper 15.
The pressure chamber 16 of the caliper 15 is supplied with pressure oil through a conduit 18 from a master bag 17 when a brake pedal (not shown) is depressed. It is connected by a pipe line 19 to a pressure oil source 20 such as an oil pump. In addition, pipe line 1

作されたか否かが判定される。Now, when the control is started, data such as vehicle speed, shift bonding, and operation/non-operation of the brake device IO are read in step #l. Next, in step #2, it is determined whether the vehicle speed is less than or equal to the set vehicle speed (when the vehicle is stopped), and in step #3, it is determined whether the brake is off (non-operating), and in the next step #4. It is determined whether the shift lever 8 has been shifted from the neutral (N) range to the drive (D) range.

して、ブレーキ装置ＩＯを非作動とする。Step #2. #3. If the determination in #4 is YES, that is, when the vehicle is stopped and the brake device IO is inactive, and the shift lever 8 is operated to switch from neutral to drive range, the first The on-off valve 21 is "open" and the second on-off valve 22 is "closed". Therefore, pressure oil is supplied from the pressure oil source 20 to the pressure chamber 16 of the caliper 15 through the conduit 19, and the brake device IO is operated. In this case, the brake force is gradually released from the orifice 24, and the release speed is:
It is determined by the set diameter of the orifice 24. After that, increment the internal timer T defined on the program and wait for the set time to elapse (step #
6, #7) When the set time K has elapsed, the first on-off valve 21 is closed, the second on-off valve 22 is opened, and the brake device IO is deactivated in step #8.

解放したので車両はスムースに発進することができる。With the above control, when starting with the brakes released, the brake device 10 is temporarily activated, so even if the shift lever 8 is switched from neutral to drive range without stepping on the brake, the shift lever 8 can be switched from neutral to drive range at the same time. The vehicle can start safely after adjusting its driving position. Further, since the orifice 24 is provided to gradually release the brake force, the vehicle can start smoothly.

If the answer is "No", the brake control as described above is not necessary and the process returns directly.

The starting of the vehicle may be doubly restricted by controlling the opening to be fully closed or close to this.
