Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vehicle seat control device that electrically controls the seating posture of a vehicle seat. The present invention relates to a vehicular seat control device that prohibits manual operation and automatically switches a control mode to an OFF state when a manual operation switch is not operated for a predetermined period of time or more.

2. Description of the Related Art Conventionally, this type of technology is disclosed in Japanese Patent Application Laid-Open No. 58-53524, in which an airbag is built in to form a support part of a predetermined shape on the surface of a seat, and a switch corresponding to each support part is used. A seat control device has been proposed that operates an air pump to supply air by operating the seat.

Problems to be Solved by the Invention According to the conventional technique, a number of switches corresponding to the types of each support part is required, making the operation complicated. In addition, if these many switches are operated without visual confirmation, they may be operated incorrectly, and when installed in a vehicle, the seat control device may be activated if the switch is accidentally touched while the vehicle is running. .

Means for Solving the Problems The present invention has been devised in view of the above-mentioned problems, and provides posture control of the vehicle seat in response to the output of a mode selection means mounted on the vehicle in response to the operation of a manual operation switch. In a seat control device configured to notify a control mode by a sound generation means, the seat control device is connected to a start input section or a power supply section of the sound generation means in order to prohibit the sound notification sound when the mode selection means successively switches modes. The present invention provides a vehicle seat control device comprising a prohibition means configured to reset or turn off a mode selection means in response to a manual operation switch being left unattended for a predetermined period of time.

Functions The present invention performs the following functions by means of the diagonally upward configuration means. The attitude control mode is cyclically switched in response to the output of the mode selection means corresponding to the operation of the manual operation switch, and the set control mode is notified by the sound generation means, while the manual operation switch is pressed to select the control mode. During continuous operation, the prohibiting means prohibits the audio notification sound, and if the manual operation switch is not operated for a predetermined period of time or more, the reset means operates to reset the mode selection means to the initial state or turn off the power.

Embodiments Hereinafter, preferred embodiments of the present invention will be described based on the accompanying drawings.

In the drawing, 1 is a manual operation switch located near the seat of the vehicle for the passenger to operate, 2 is a seat control circuit as a mode selection means, 3 is a sound generation unit as a sound generation means, and 4 is a manual operation switch operated by a passenger. A first timer circuit serves as an inhibiting means, and a second timer circuit 5 serves as a resetting means.

To explain each circuit in more detail, the manual operation switch 1 includes:
A select switch 11 for selecting a control mode, and an increase/decrease switch 12 for increasing/decreasing the amount of posture control of the vehicle seat.
．． It consists of 13.

In this case, the amount of posture control of the vehicle seat refers to the amount of airbags installed in each of the lumbar support part 1 on the back of the seat, the site support part on the side part, and the waist support part 1 on the crotch part. This refers to the amount of air pressure inside the seat, the amount of angle of the reclining part of the seat, the amount of control of the lid that adjusts the height of the seat, and the amount of control of the slider that adjusts the fore-and-aft position of the seat.

The seat control circuit 2 also includes first to third waveform shaping circuits 21 to 23 connected to the manual operation switch, respectively;
A counter circuit 24 connected to the select switch 11 via the first waveform shaping circuit 21, a control circuit 25 and an L CD control circuit 26 connected to the first to sixth output parts Q1 to Q6 of the counter circuit 24, It is composed of an LCD display circuit 27 connected to the output part of the LCD control circuit 26, diodes D, , D2, and an actuator 28 connected to the output part of the control circuit 25.

Here, the output signals of the first to sixth output parts Q1 to Q6 of the counter circuit 24 are all It □ I+ when the control mode is in the initial state or reset state, for example.
level, and then each time the select switch 11 is pressed once, I
f I If level part circulates and switches. The control circuit 25 includes an air pump for adjusting the internal pressure of the airbag or a reversible motor for adjusting the seat position such as the reclining angle to control the posture of the seat according to the output state of the first output section Q1 to the sixth output section Q6. A signal is derived to an actuator 28 consisting of. Further, the LCD control circuit 26 derives a signal to the LCD display section 27 to display the control mode according to the output states of the first output section Qlfx to the sixth output section Q6.

Further, the sound generation section 3 includes a sound synthesis circuit 31 for synthesizing a sound signal for notifying the seat control mode, a diode, and a speaker 32.

The address input sections A to A6 of the speech synthesis circuit 31 are connected to the first output section Q1 to the sixth output section Q6 of the counter circuit 24, respectively, and the start input section ST is connected to the first output section Q1 to the sixth output section Q6 of the counter circuit 24. The busy output section BUSY is connected to the one waveform shaping circuit 21, and the busy output section BUSY is connected to the counter circuit 24 through the diode D3 and the second timer circuit 5.
Each is connected to SET.

Here, when a signal is input to the start input section ST, the voice synthesis circuit 31 synthesizes a notification voice corresponding to the input signal of the address input sections A1 to 80 and outputs it from the voice output section OUT, while This circuit outputs an interrupt prohibition signal from the output section BUSY while the notification audio signal is being output.

The first timer circuit 4 is composed of a delay circuit, and in response to the operation of the select switch 11, a start signal is output for a predetermined period of time 1. (After seconds J, for example, 1 (second), a start signal is input to the start input section ST of the speech synthesis circuit 31, but if the select switch 11 is further operated during the time limit operation, the time limit operation starts again from the beginning. In other words, the time limit operation starts from the beginning again. This circuit does not input a start signal to the start input section ST of the speech synthesis circuit 31 while the select switch 11 is repeatedly operated at time intervals shorter than time 1. (seconds) to sequentially switch control modes.

The second timer circuit 5 is also composed of a delay circuit, and starts a time-limiting operation for a predetermined period of 12 (seconds) in response to the stop of the interrupt prohibition signal output from the busy output section BUSY of the speech synthesis circuit 31. For example, a reset signal is inputted to the reset input section RESET of the counter circuit 24 after a row of 5 or 5, but if an interrupt disable signal is input during the timer operation, the timer operation starts again. This circuit does not input a reset signal to the reset input section RESET of the counter circuit 24 while the interrupt prohibition signal is output from the busy output section BUSY at time intervals shorter than the predetermined time t2 (seconds).

When the select switch 11 is repeatedly operated, the seat posture control mode is cyclically switched via the counter circuit 24, and the set control mode is displayed on the LCD display section 27.
On the other hand, when the select switch 11 is continuously and repeatedly operated to select the control mode, the notification sound from the audio generator 3 is prohibited by the delay action of the first timer circuit 4, and the manual If the operation switch 1 is not operated for a predetermined period of time t2r, the second timer circuit 5 resets the counter circuit 24 to an initial state that does not belong to any control mode.

The prohibition of the notification sound by the prohibition means may be done by stopping the power to the sound generation means E1, and the stop of the mode selection means by the reset means may be done by turning off the power to the mode selection means.

Effects of the present invention The present invention has the following effects due to its slanted structure. In other words, since the control mode can be selected and controlled using the select switch, the number of switches to be operated is small regardless of the type of support part, etc., and the type of selected control mode is notified by voice, so it is not necessary to switch by groping. There is no erroneous operation when operating the control mode, there is no unnecessary notification sound when the control mode is fast forwarded, and if you leave the seat without controlling the seat, the control mode will automatically reset to the initial state. The effect of providing a vehicle seat control device that is extremely easy to operate and has excellent safety because it does not malfunction even if the switch is touched by mistake while the vehicle is running.
