Here, the output level is set to increase as the obstacle is closer to the vehicle, and the output level is set to Th1 and Th in descending order.
2, Th3. On the other hand, when there is no obstacle behind, the sensor output S ₁₁ becomes low level (S ₁₁ = 0).
Then, the sensor output S ₁₁ is sent to the vibration signal generator 12 and the control signal generator 13.

The vibration signal generator 12 is a rear obstacle sensor.

As the vibrating portion of the seat surface 15 moves from the front to the rear as the obstacle approaches, the distance between the driver and the obstacle is greater than that of a device that simply vibrates the vibrating body to notify the presence or absence of an alarm. Can be understood as a change in the position of the vibrating part. Therefore, various contents of the warning can be transmitted to the driver by the vibration. In addition, compared with general rear obstacle warning devices that change the pitch (frequency) of the warning sound to inform the distance to the obstacle, the driver can concentrate on backward driving. , It does not make passengers feel uncomfortable or anxious.

Here, when the approach sensor 21 detects the approach of the preceding vehicle, for example, a case where the vibrators V6, V5, and V4 among the vibrators V1 to V9 are sequentially vibrated at predetermined time intervals will be specifically described. . FIG. 7 is a flowchart showing the operation of the second embodiment.

In FIG. 7, the approach sensor 21 detects the approach of the preceding vehicle, and the sensor output S ₂₁ is at a high level (S ₂₁ =
In step 201, in step 201, a vibration signal is generated from the vibration signal generation unit 12 and output to the selection unit 14, and at the same time, the control signal generation unit 23 turns on the relay RY6 and turns off other relays. A control signal is generated and output to the selection unit 14.

In step 202, the relay RY6 is turned on by the control signal from the control signal generator 23, and the vibration signal input to the relay RY6 is transmitted to the output side of the relay RY6. At this time, the other relays RY1 to RY5,
Since RY7 to RY9 are in the OFF state, the vibration signal input to each relay is not transmitted to the output side. In step 203, the vibrating body V6 is driven and vibrated by the vibration signal output from the relay RY6.

In step 204, the control signal generator 23 measures the elapsed time t ₆ after the generation of the control signal for turning on the relay RY6, and the elapsed time t ₆ vibrates the preset vibrating body V6. Allowed time interval Td ₆
Is determined. Until the elapsed time t ₆ exceeds the time interval Td ₆ , the control signal generator 23 relays the relay RY.
A control signal for turning ON 6 is continuously output. When the elapsed time t ₆ exceeds the time interval Td ₆ , the control signal generator

In step 205, the relay RY6 is turned off by the control signal from the control signal generator 23, and the vibration signal is not output from the relay RY6. In step 206, the vibration of the vibrating body V6 is stopped. Step 207
Then, in response to the control signal from the control signal generator 23, the relay RY5 is turned on simultaneously with step 205, and the relay R
The vibration signal input to Y5 is transmitted to the output side of the relay RY5.

In step 208, the vibrating body V5 is driven and vibrated by the vibration signal output from the relay RY5. In step 209, the control signal generator 23 measures the elapsed time t ₅ after the generation of the control signal for turning on the relay RY5, and the elapsed time t ₅ vibrates the vibrating body V5 set in advance. It is determined whether the time interval Td ₅ has been exceeded. Until the elapsed time t ₅ exceeds the time interval Td ₅ , the control signal generator 23 turns on the relay RY5.
The control signal for setting the state is continuously output. Elapsed time t
_{When 5} exceeds the time interval Td ₅ , a control signal generating unit 23 generates a control signal for turning on the relay RY4 and turning off the other relays, and the control signal is output to the selecting unit 14 and step 21
Move to 0.

At step 210, the relay RY5 is turned off by the control signal from the control signal generator 23, and the vibration signal is not output. At step 211, the vibration of the vibrating body V5 is stopped. In steps 212 to 216, the same as steps 207 to 211 above,
The relay RY4 is continuously turned on for the time interval Td ₄ to vibrate the vibrating body V4, and when the time interval Td ₄ has passed, the relay RY4 is turned off to stop the vibration of the vibrating body V4.

Vibration signal is no longer generated and all
Vibration of the vibrating body is stopped.

When the sensor output S ₂₁ of the proximity sensor ₂₁ becomes a low level (S ₂₁ = 0) during the operation of steps 201 to 218, the vibration signal of the vibration signal generator 12 is generated. The vibration of all the vibrating bodies is stopped because it disappears. FIG. 8 shows a time chart of the above series of operations. As shown in the figure, the approach sensor 21 detects the approach of the preceding vehicle and the sensor output S ₂₁ is at a high level (S ₂₁ = 1).
Then, at the same time when the vibration signal of the vibration signal generating unit 12 is generated, the relays RY6, RY5 and RY4 are sequentially arranged at the time interval T.

= 0), the vibration signal of the vibration signal generation unit 12 stops and the vibrating body disappears. This vibration operation is shown in FIG.
As shown in, the vibration moving from the rear of the seat surface 15 to the front is transmitted to the driver.

The time intervals Td ₆ , Td ₅ and Td ₄ can be set arbitrarily. For example, each time interval is equal to Td ₆ = T.
It is also possible to set d ₅ = Td ₄ = d. As described above, according to the second embodiment, when the preceding vehicle approaches and the safe inter-vehicle distance cannot be maintained, the vibrating bodies V6, V5 are generated.
By selecting V4 and causing it to vibrate in time series, the driver is given a tactile sensation of vibration moving from the rear of seat seat surface 15 to the front, and an alarm is issued to inform the driver of the approach of the preceding vehicle. As a result, compared to a device that simply vibrates the vibrating body to notify the presence or absence of an alarm, the vibrating part is the seat seat surface.
By moving from the rear of 15 to the front, it is possible to present the contents as a warning of attention to the front, and to transmit the contents of various warnings to the driver.

Next, a third embodiment will be described.
In the third embodiment, a case will be described in which the vehicular warning device of the present invention is applied to a device that detects a half-door and issues a warning to the driver. FIG. 10 is a block diagram showing the configuration of the third embodiment. However, the same components as those in the second embodiment are designated by the same reference numerals and the description thereof will be omitted.

In FIG. 10, the configuration of the third embodiment is different from that of the second embodiment in that a door sensor 31 is provided on each door of the vehicle instead of the proximity sensor 21, and a control signal generator 23 is provided. Instead, the control signal generator 33 is used.
The door sensor 31 includes, for example, a door sensor 31A provided on the driver side door, a door sensor 31B provided on the passenger side door, a door sensor 31C provided on the right rear seat door, and a rear seat left side sensor 31C. Door sensor 31 installed on the door

_31A to S _31D is by the opening and closing states of the respective door, high level when in the state in which the door is opened (for example, S _31A =
1) and becomes low level (for example, S _31A = 0) when the door is in the closed state.

The control signal generator 33 includes a door sensor 31A,
Sensor outputs from 31B, 31C, 31D S _31A , S _31B ,
When _S31C and _S31D become high level, relay R respectively
A control signal for turning on Y1, RY7, RY3 and RY9 is generated. The other configurations are the same as the configurations of the second embodiment, and thus the description thereof will be omitted. Next, the operation of the third embodiment will be described.

FIG. 11 is a flow chart showing the operation of the third embodiment. Referring to FIG. 11, the case of warning the half door of the driver's side door will be described. Step 301A
Then, the level of the sensor output S _31A of the door sensor 31A is determined. Sensor output S _31A is low level (S _31A =
In the case of 0), since the door is in the closed state, the half-door alarm operation is not performed. Sensor output S _31A is high level (S
_{If 31A} = 1), the process proceeds to step 302A.

In step 302A, a vibration signal is generated from the vibration signal generation unit 12 and output to the selection unit 14, and a control signal for turning on the relay RY1 is generated from the control signal generation unit 33 to generate the selection signal.

The Y1 is turned on, and the vibration signal input to the relay RY1 is transmitted to the output side of the relay RY1.

In step 304A, the vibrating body V1 is driven and vibrated by the vibration signal output from the relay RY1. In step 305A, the level of the sensor output S _31A of door sensor 31A is determined. When the door is not closed and the sensor output S _31A is at a high level (S _31A = 1), the control signal generator 33 continuously outputs a control signal for turning on the relay RY1. The door is closed and the sensor output S
_{When 31A} becomes low level ( _S31A = 0), a control signal for turning off the relay RY1 is output from the control signal generator 33, and the process proceeds to step 306A.

In step 306A, the relay RY1 is turned off by the control signal from the control signal generator 33, and the vibration signal is not output from the relay RY1. In step 307A, the vibration of the vibrating body V1 is stopped. In this way, by the operation of steps 301A to 307A, the driver is given an alarm indicating the half-door state on the driver's seat side. Further, with respect to the passenger side door, the rear right side door, and the rear left side door, when the half-door state is detected in the same manner as the operation on the driver side door, the vibrating body V7, the vibrating body V3, and the vibration are detected. Each body V9 vibrates and the driver is notified of the alarm.

FIG. 12 shows a time chart of the above series of operations. In the figure, an example is shown in which a half door of the passenger seat side door and the rear seat right side door are detected. When the output of the door sensors 31B, 31C becomes high level, the vibration signal of the vibration signal generating unit 12 is generated, and the door sensors 31B, 31C are generated.
While the high level output is generated from the relay RY7, RY
3 becomes an ON state, and the corresponding vibrating bodies V7 and V3 vibrate. At this time, since the outputs of the door sensors 31A and 31D are at a low level, vibration does not occur. This vibration motion is
As shown in FIG. 13, first, when the front door half doors and the rear seat right door half doors are detected, the vibrating body V7 located on the front left side of the seat seat surface and the vibrating body V3 located on the rear right side.

Then, when the door on the right side of the rear seat is closed, the vibration of the vibrating body V3 stops. In this way, the portion of the seat seat surface 15 corresponding to the position of each door vibrates and an alarm indicating a half-door state is transmitted to the driver.

As described above, according to the third embodiment, by selecting and vibrating the vibrating body corresponding to the position of the door in the half-door state, an alarm for notifying the driver of the half-door is issued. This allows the driver to recognize the position of the door in the half-door state, which cannot be transmitted by the device for notifying the half-door by the alarm sound or the single warning light, by the vibrating position of the seat seat surface 15.
