Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic change for a vehicle that electrically changes gears, and more particularly to an automatic change that can prevent the vehicle from being stolen.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, in vehicles, a gear shift operation device has been widely used in which the operation of a change lever is transmitted to a transmission by a cable or a rod to perform a gear shift operation.

On the other hand, with recent breakthroughs in computer technology, a shift range is selected by push operation of a switch operation unit, etc., and a drive signal is generated based on the selection of a shift range to drive an actuator such as a drive motor. Various vehicle automatic changes have been proposed in which the transmission is controlled to be switched to a parking P, reverse R, neutral N, drive D, second S, or low L shift range (for example, in actual development 60-. 168629).

[0004]

[Problems to be solved by the device]

 By the way, in vehicles, it may be necessary to leave the vehicle with the key attached. For example, if the engine is warmed up during a severe winter, press the key to turn on the ignition switch, start the engine and perform warm-up operation, and keep the driver indoors while the air condition starts to operate. May take up heating.

However, the conventional vehicle has a problem that the vehicle may be stolen if the vehicle is left with the key attached.

In order to solve the above-mentioned problems, the applicant of the present application sets the shift range to the drive P, the second S, or the low L by operating the switch when the shift range is set to the parking P when the vehicle is stopped in the vehicle automatic change. The vehicle cannot be driven at all unless it is operated in the driving range, etc., and it is possible to prevent theft if the switch operating part can be removed and taken out even with the key attached. We have developed an auto-change that can be installed as much as possible, but in this case, if a switch operating part that can generate the same signal as the switching signal of the removed switch operating part is used, the transmission will reach the driving range. There is concern that gear shifting may be performed.

In view of the above point, an object of the present invention is to provide an auto change capable of preventing vehicle theft even more reliably even when the engine is operating.

[0008]

[Means for Solving the Problems]

 Therefore, in the auto change according to the present invention, the switch operation unit is driven in the vehicle interior by generating a shift signal from the switch operation unit to drive the actuator to switch the transmission to a predetermined shift range. A mechanism for detachably mounting the switch operating part is provided, while at least one terminal for generating an identification signal is provided in the switch operating part so that the switch operating part can be identified. And

Here, the structure of the automatic change may be any structure as long as the gear shift operation is performed by the switch operation. For example, the switch operating unit may be of push button type, dial type or lever type. Further, the switch operating section and the microcomputer may be connected by a signal line, or signals may be exchanged by radio waves or the like. Further, a drive motor can be adopted as the actuator, but a drive source other than that may be used.

Further, in order to reliably prevent the vehicle from being stolen, it is necessary to set the shift range to parking when the vehicle is stopped, but it is preferable that the parking P be automatically set. Further, the attachment / detachment mechanism of the switch operation unit may be any kind, and if the mechanism is constructed properly, the switch operation unit can be installed at a desired place in the vehicle interior.

Further, the switch operating portion may be identified by mechanical identification, for example, a terminal of the switch operating portion may be formed as a protrusion having a special shape, and the protrusion may be fitted into a recess on the mounting portion side for identification. Contact type identification, for example, a coded identification signal may be added to the switching signal from the switch operation section and the control system decoder may identify this.

[0012]

[Action]

 In the present invention, the switch operating portion is made detachable, and the attachment / detachment mechanism is provided so that the transmission can be parked even when it is necessary to keep the key or leave the vehicle while the engine is operating. If the switch operating part is removed and brought out, the transmission will not shift to the driving range and the vehicle will not be in a running state without the occupant's knowledge. In addition, the switch operation unit can be installed in a place where the driver prefers, and the gear shifting operation becomes easier.

Further, since the switch operation portion is provided with the terminal for generating the identification signal, whether the switch operation portion is a legitimate switch operation portion is discriminated, and the switch operation capable of generating the same signal as the switching signal of the legitimate switch operation portion. When the parts are used, the transmission is never shifted into the driving range.

Next, the operation will be described using a flowchart.

In the control unit 3, as shown in FIG. 7, first, a control system is initially set (step S1), signals of various switches are input (step S2), and an automatic parking process is performed (step S1). In step S3), the processing content of the switching signal of the switch operating unit 2 is determined (steps S4 to S9), and according to the determination result, the parking, reverse, neutral, drive, second, or low speed shift processing is performed to shift the speed. The machine is switched to a predetermined range (steps S10 to S15).

Further, at a predetermined timing, the decoder control 5 determines whether the process is the switch loading process or the switch removal process, and the loading process and the remote switch 2 identification process or the removal process are executed accordingly. It

Next, each processing content will be described in detail.

“Switch removal processing”

In the switch take-out process, as shown in FIG. 9, it is first determined whether or not the eject switch 1c is turned on (step S31), and if the eject switch 1c is off, the remote switch 2 needs to be taken out. Since it does not exist, the process ends as it is.

On the other hand, when the eject switch 1c is ON, whether or not the vehicle speed is 0 km / H and whether or not the vehicle is traveling (step S32), and whether or not all the switches are OFF when the vehicle is stopped Is determined (step S33). If the car is running or some of the switches are on, the removal process is not performed. If all the switches are off while the car is stopped, the Solenondo 1b is turned on and the remote switch 2 is turned on. When the removal of the remote switch 2 is detected by the attachment / detachment detection switch 6c (step S35), the solenoid 1b is turned off (step S35), and the process ends.

As described above, by operating the eject switch 1c, the remote switch 2 is automatically removed, and it is possible to easily carry the remote switch 2 out of the passenger compartment.

“Switch loading process”

In the switch loading process, as shown in FIG. 8, it is first determined whether or not the attachment / detachment detection switch 6c is turned on (step S41). If the attachment / detachment detection switch 6c is OFF, the remote switch 2 is Since the loading process is unnecessary as it is taken out, the process ends.

On the other hand, when the remote switch 2 is attached to the recess 1a of the steering wheel 1 and the attachment / detachment detection switch 6c is turned on, whether the remote switch 2 belongs to the vehicle based on the coded identification signal in the switching signal. Whether or not it is determined (step S42), if the remote switch 2 is not for the vehicle, it is determined to be another remote switch 2 and the engine starting process is not performed.

When the remote switch 2 belongs to the vehicle, it is determined whether the engine start button is turned on (step S43) or the engine stop button is turned on (step S44), and the start button is pressed. When is turned on, the engine is started (step S45), and when the stop button is turned on, the engine is stopped (step S46).

When the remote switch 2 is loaded on the handle 1 in this manner, the remote switch 2 is identified, and it becomes possible to start and stop the engine and switch the shift range.

“Automatic parking process”

First, as shown in FIG. 10, it is determined whether or not the ignition switch is ON (step S301). If the ignition switch is ON, it means that the vehicle is in a traveling state and therefore whether or not the parking brake is in operation. Whether or not the seat belt is worn is determined whether the attachment / detachment detection sensor 6c is ON (removal) or OFF (loading) (steps S302 to S304). When the parking brake is not operated, the seat belt is worn, and the remote control switch 2 is loaded, it is determined that the running state should be continued, the attachment / detachment flag is set to 1 and the process ends ( Step S305).

When the ignition switch is OFF, it is determined whether or not the neutral inhibit switch is ON (step S306). In the neutral state, the automatic parking process is unnecessary and the process is terminated as it is.

On the other hand, if the vehicle is not in the neutral state, it is determined whether or not the brake is depressed (step S307), and if the brake is not depressed, it is determined whether or not the vehicle speed is 3 km / H or less (step S307). S308), if the vehicle speed is 3 km / H or less, the vehicle is in a stopped state, so the motor operation routine is processed, the transmission is shifted to the parking range P and the processing is terminated (step S309), and the vehicle speed is 3K. If m / H or more, the vehicle is still in a traveling state and automatic parking should not be processed, so the processing ends.

If the brake is depressed, the process proceeds to step S304 described above, and it is determined whether the attachment / detachment detection sensor 6c is ON / OFF. If the remote control switch 2 is not attached, it is determined whether the attachment / detachment flag is 1 (step S310), and if the attachment / detachment flag is 1, it is determined whether the vehicle speed is 3 Km / H or less (step S311). ) If the vehicle speed is 3 Km / H or less, the condition for automatic parking is set. Therefore, after setting the attachment / detachment flag to 0 (step S312), the motor operation routine is processed (step S309) to perform the parking range. The speed is changed to P and the process is ended.

On the other hand, when the attachment / detachment flag is 0, or when the vehicle speed is 3 Km / H or more, there is no need for automatic parking, or the vehicle is in a running state, and the conditions for automatic parking are not satisfied. The process ends.

“Parking range processing”

When the parking push button 2a of the remote control switch 2 is operated, as shown in FIG. 11, it is determined whether or not the vehicle speed is 3 Km / H or higher (step S101). If it is 3 Km / H or higher, Since the vehicle speed is still high and the vehicle should not be parked, the processing is terminated as it is.

When the vehicle speed becomes 3 Km / H or less, the process of the motor operation routine (step S102) is performed, the transmission is shifted to the parking range P, and the process ends.

“Reverse range processing”

When the reverse push button 2b of the remote control switch 2 is operated, as shown in FIG. 12, it is determined whether or not the vehicle speed is 3 Km / H or more (step S111), 3 Km / H or more. In this case, when shifting from the drive D, second S or low L range to the lever range R, the gears of the transmission are subject to load and may be damaged. .

When the vehicle speed becomes 3 Km / H or less, it is determined whether or not the transmission is in the parking P (step S112). If the transmission is in the parking P, is the brake stepped on? Whether or not it is determined (step S113), if the brake is depressed, the process of the motor operation routine is performed (step S114), the transmission is shifted to the reverse range R, and the process is terminated.

When the transmission is not in the parking P, the motor operation routine is processed (step S114), the speed is changed to the reverse range R, the processing is terminated, and the brake is not depressed. It is determined that the condition for shifting to the reverse range R is not satisfied, and the process is ended as it is.

“Neutral range processing”

Further, in the neutral range processing, as shown in FIG. 13, it is determined whether or not the transmission is in the parking P (step S121). Determines whether or not the brake pedal is depressed (step S122). If the brake pedal is depressed, the motor operation routine is processed (step S123) to shift the transmission to the neutral range N. Finish the process.

When the transmission is not in the parking P or when the brake is not pressed, the processing of the motor operation routine is immediately performed (step S123), and the transmission is shifted to the neutral range N.

“Drive or second range processing”

In the low range processing, as shown in FIG. 14, it is determined whether or not the transmission is in reverse R (step S151). This is because when the vehicle speed is, for example, 3 Km / H or more and the speed is changed from the reverse range R to the drive or the second ranges D and S, the transmission gears may be damaged.

If the transmission is not in reverse R, it is determined whether the transmission is in parking P (step S152). If it is in parking P, is the brake applied? Whether or not it is determined (step S153), if the brake is pressed, the processing of the motor operation routine is performed (step S154), the speed changer is shifted to the drive or the second range D, S, and the processing is terminated. .

When the transmission is not in the parking P, the motor operating routine is immediately processed (step S154) to shift to the low range L and the processing is completed, and the transmission is set to the reverse R. If the vehicle speed is 3 Km / H or more (step S155), it is judged that the transmission gears have been damaged if the vehicle speed is 3 Km / H or more. When it becomes 3 Km / H or less, the processing of the motor operation routine (step S154) is performed to shift to the low range L, and the processing ends.

“Low-range processing”

In the drive or second range processing, as shown in FIG. 15, it is determined whether or not the transmission is in reverse R (step S131). This is because when the vehicle is traveling at a speed of 3 km / h or higher and the speed is changed from the reverse range R to the low range L, the gears of the speed change gear may be damaged and damaged.

If the transmission is not in reverse R, it is determined whether the transmission is in parking P (step S132), drive D or second S, and drive D or If it is not in the second S, the motor operating routine is processed (step S134), the transmission is shifted to the low range L, and the processing is terminated.

When the transmission is in reverse R, it is determined whether the vehicle speed is 3 Km / H or higher (step S135). If it is 3 Km / H or higher, the gears of the transmission are damaged. If there is a possibility that the process ends without performing any processing and the speed falls below 3 Km / H, the processing of the motor operation routine (step S134) is performed to shift the transmission to the range of drive D or second S, and the processing is performed. finish.

Further, since there is no possibility of damage to the transmission when the transmission is in the parking P, if the brake is depressed (step S136), the processing of the motor operation routine (step S134) is performed. Then, the transmission is shifted to the range of the drive D or the second S and the processing is terminated. If the drive D or the second S is set, it is determined whether the vehicle speed is 100 km / H or more (step S137). , 100 Km / H or more, a sudden downshift may cause a forward throwing load on the occupant, and the gears of the transmission may be damaged. Therefore, the processing is terminated as it is, and 100 Km / H or less, The process of the motor operation routine (step S134) is performed to shift the transmission to the range of the drive D or the second S, and the process ends.

“Operating Routine Processing”

In the processing of the motor operation routine, as shown in FIG. 16, it is determined whether or not the motor flag is 1 (step S20). If the flag is 0, that is, the main motor 4a is normal, the main motor 4a Is turned on to turn off the sub-motor display of the motor indicator 6k (steps S21 and S22), and when the flag is 1, that is, when the main motor 4a is defective, the sub-motor 4b is turned on and the sub-motor indicator 6k is displayed. It is displayed (steps S23 and S24).

Next, it is determined whether or not the motor is locked, that is, the motors 4a and 4b are defective (step S25). If the motor is not locked, it is determined whether or not the range of the transmission is the range selected by the remote switch 2. If it is determined (step S26) and the positions match, that is, if the gears are shifted to a predetermined range, the motors 4a and 4b are turned off (step S27) and the process ends.

Further, when the driving main motor 4a or sub motor 4b is locked for some reason, it is determined whether or not the motor flag is 1 (step S28), and when the motor flag is 0, the main flag is set. The motor 4a is turned off, the sub motor 4b is turned ON, the motor flag is set to 1 (steps S29, S210, S211), and the process moves to step S26 to determine whether the positions match. If the motor flag is 1, the sub motor 4b Is turned off, the main motor 4a is turned on, the motor flag is set to 0 (steps S212, S213, S214), and the process proceeds to step S26 to determine whether or not the positions match. Thus, the gear shifting process is performed by replacing the motors 4a and 4b. .

In the above-described auto change of the present embodiment, the remote control switch 2 is detachably attached to the handle 1 and the transmission is switched to the parking P when the remote control switch 2 is removed, so that the engine is operated. Even if it is necessary to get out of the vehicle as it is, if the remote control switch 2 is detached and taken out, the transmission is not shifted to the travel range and the vehicle can be reliably prevented from being stolen. Moreover, since the transmission is automatically switched to the parking P when the remote control switch 2 is removed, the vehicle theft can be more reliably prevented.

Further, in the auto change of the present embodiment, the switch 2 is discriminated based on the identification signal from the remote control switch 2, so that the remote control switch 2 which generates a similar switching signal can be eliminated, which further improves the operation. You can definitely steal your vehicle.
