Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a vehicular seat device and a vehicular seat combined type notification system, and in particular, to a seat, when an obstacle or other vehicle approaches when traveling on a general road or an expressway or parking at a predetermined parking lot. The present invention relates to an apparatus in which a vibration generator provided is vibrated to notify an occupant.
[0002]
[Prior art]
  Conventionally, the driver of the vehicle recognizes the surrounding situation mainly visually from the position of the driver's seat through the windshield, the left and right door windows, or through the rear view mirror and the left and right door mirrors. Judgment of lane change and speed control to provide appropriate inter-vehicle distance between front and rear vehicles, smooth lane change while avoiding collision with other vehicles traveling on different lanes, especially parking lot When parking in a car, etc., the driver pays attention not only to other vehicles but also to various obstacles such as poles and fences.
[0003]
  By the way, the driver of the vehicle moves forward or backward while relying solely on the driver's visual judgment of the surrounding situation during driving or parking, so the driver approaches the vehicle for some reason. If you are not aware of other vehicles and obstacles, there may be a case that leads to a collision. In view of this, recently, various notification devices have been proposed in which other vehicles and obstacles approaching the surroundings of the vehicle are detected by sensors or devices to notify the driver.
[0004]
  For example, in the “vehicle approach warning device” described in Japanese Patent Application Laid-Open No. 10-67301, an approach warning device having a distance measuring device, a vehicle speed measuring device, and the like is provided so that the vehicle and the object ahead The warning distance is obtained from the relative speed, and when the distance between the vehicles becomes smaller than the warning distance, the seat belt tension is increased and a warning sound is generated to warn the driver. Here, for reference, the “swelling operation prevention device” described in Japanese Patent Application Laid-Open No. 10-258655 incorporates a vibration means for generating vibration by the rotation of the motor in the headrest, so that the driver can operate the switch. As a result, the motor rotates and the entire headrest vibrates via the vibration means, so that the driver is awakened.
[0005]
[Problems to be solved by the invention]
  As described above, according to the “vehicle approach warning device” described in Japanese Patent Laid-Open No. 10-67301, when the traveling vehicle and the front object approach abnormally, the seat belt tension is increased, If the seat belt is loosely tightened, the driver's body is shaking, the clothing is thick or layered, the driver will be alerted. In addition, there is a problem that an abnormal approach state cannot be reliably notified and the seat belt is fastened rapidly, so that an unfamiliar driver feels surprise and discomfort.
[0006]
  Further, there is a problem that the degree of approach of the front object cannot be determined only by increasing the seat belt tension. Furthermore, the approach of the rear object cannot be detected at all, and the obstacle behind the host vehicle when moving backward when approaching another vehicle traveling on the expressway or parking. There is a problem that no information can be reported. On the other hand, an alarm sound is generated. However, when listening to car radio or favorite music at a relatively large volume, there is a possibility that the alarm sound may be missed.
[0007]
  An object of the present invention is to be able to reliably report the approach of an obstacle including another vehicle to the host vehicle from the front, rear, left and right directions by vibration of the vibration generator, to be able to notify the degree of approach of the obstacle by the magnitude of the vibration, For example, the drive mode of the vibration generator can be changed according to the traveling state of the vehicle, and the drive gain of the vibration generator is reduced when a collision avoidance operation is performed on an obstacle.

It is an example at the time of applying this invention to the vehicle seat combined use alerting | reporting system.
  First, an automobile 1 (hereinafter referred to as a host vehicle) driven by a driver is a general one as shown in FIG. 1, and is a manual transmission type in which a shift shift is performed manually.
[0030]
  The front bumper on the front side of the host vehicle 1 is provided with a left front detection sensor 2 for detecting obstacles and other vehicles approaching the front left side of the host vehicle 1 at the left corner thereof, and the right side thereof.

Here, these detection sensors 2 to 6 corresponding to the obstacle detection means are constituted by ultrasonic sensors. These detection sensors 2 to 6 may be a laser / radar sensor or an infrared sensor, or may be a small auto-focus type camera, and the presence / absence of a vehicle is determined by analyzing an image photographed by the small camera. In addition, when a vehicle is detected, the inter-vehicle distance L at that time may be obtained based on the focal length.
[0032]
  Next, vibrators (corresponding to vibration generators) 13 to 15 provided on the driver seat 10 will be described with reference to FIGS.
  The driver seat 10 includes a horizontal seat cushion 11 on which a driver sits during driving, and a seat back 12 pivotally supported by the rear end portion of the seat cushion 11 to support the driver from the rear side. ing.
[0033]
  Then, circular recesses are formed in the vicinity of the front end of the seat cushion 11 and on the left and right surface portions where the left and right thighs of the driver abut, respectively, and a cylindrical right vibrating body ( (Hereinafter referred to as “R vibrating body”) 13 and a cylindrical left vibrating body (hereinafter referred to as “L vibrating body”) 14 are provided in the left concave portion.

Is provided. Here, the vehicle seat device 16 is configured by the three vibrating bodies 13 to 15 and the driver seat 10.
[0034]
  Since these vibrating bodies 13 to 15 have the same configuration, the R vibrating body 13 will be described. As shown in FIG. 3, as shown in FIG. 3, an electric circular magnet 18 incorporating a thin coil inside the protective case 17, and this magnet 18 is provided with an eccentric weight 32 that functions as a rotor pivotally supported by the shaft 18. That is, when a drive signal is supplied to the magnet 18 via the connection cord 9, the eccentric weight 19 is rotationally driven by the cooperation of the magnet 18 and the eccentric weight 19, and acts on the eccentric weight 19 during this rotation. The entire R vibrating body 13 is vibrated by centrifugal force.
[0035]
  Here, the magnet 18 and the eccentric weight 19 act as a drive motor. Furthermore, the rotational speed of the eccentric weight 19 can be changed by changing the frequency or voltage of the drive signal supplied to the magnet 18, thereby changing the drive gain G (vibration magnitude) of the vibrating bodies 13 to 15. Can do.
  On the other hand, the electric seat belt device 20 for the driver seated on the driver seat 10 will be briefly described. As shown in FIG. 4A, one end of the seat belt 21 is fixed to the fixing portion 22, The seat belt retractor 25 is configured to be wound around the buckle portion 23 and the shoulder support portion 24.
[0036]
  Here, as shown in FIG. 4B, a drive motor 26 is connected to the retractor 25, and the tension of the seat belt 21 can be changed by driving the drive motor 26. . By the way, it is possible to vibrate the seat belt 21 by driving the drive motor 26 alternately in the forward direction and the reverse direction every minute time.
  Next, a control system of the vehicle seat combined type notification system will be described based on the block diagram of FIG.
[0037]
  The control unit (corresponding to the control means) CU is composed of a microcomputer provided with a CPU 32, ROM 33, RAM 34, and the like, and a vehicle speed signal is sent from a main control unit (not shown) that executes engine control, travel control, etc. of the host vehicle 1. The steering angle signal, the shift position signal indicating the shift position of the shift lever, the brake signal when the brake is operated, etc. are received, the detection signals are received from the five detection sensors 2 to 6, and the audio signal is received from the microphone 30. On the other hand, the R vibrating body 13, the L vibrating body 14, the W vibrating body 15, the drive motor 26 that drives the retractor 25, and the liquid crystal display 31 are controlled to be driven.
[0038]
  The ROM 33 will be described later.LikeIn addition, the control program for the lane change notification control executed when the vehicle 1 is traveling on a general road or a highway at a vehicle speed of, for example, 30 km / hour or more, and the vehicle speed of the vehicle 1 is, for example, 30 km / hour. Control program for parking notification control executed when parking in a predetermined parking lot, and emergency vehicle notification control for detecting and notifying an emergency vehicle such as an ambulance or a patrol car. Control programs are stored in advanceHaveThe Further, the RAM 34 is provided with various numerical memories necessary for executing these controls, and various memories such as counters and buffers as necessary.
[0039]
  Next, a lane change notification control routine executed by the control unit CU will be described with reference to the flowcharts of FIGS. In the figure, reference sign Si (i = 1, 2, 3,...) Indicates each step.
  The engine is started by operating the ignition switch, and this control is started when the vehicle speed reaches, for example, 30 km / hour or more. First, the detection signals output from the three detection sensors 4 to 6 on the rear side are read (S1), and based on these detection signals, the distance L between the left rear, the right rear, and the rear center is calculated. (S2).
[0040]
  At this time, when there is no vehicle approaching the host vehicle 1, the inter-vehicle distance L is infinite. Next, based on the inter-vehicle distance L, the relative speed of the vehicle approaching rearward with respect to the host vehicle 1 is obtained by calculation (S3). This relative speed calculation is obtained by the time change of the distance between the rear vehicle and the host vehicle 1, but since this relative speed calculation technique is generally known, detailed description thereof is omitted. Next, based on the own vehicle speed and the relative speed, a distance A for alarming is calculated (S4). That is, the warning distance A changes based on the host vehicle speed and the relative speed, and takes a positive value when the host vehicle 1 and the rear vehicle are in a relative speed (the host vehicle 1 and the rear vehicle are close to each other). Suppose) Here, for example, it is assumed that the alarm distance A is determined such that the approaching distance after about 2 seconds is about 3 m.
[0041]
  Next, when the distance L with the rear vehicle is larger than the warning distance A, that is, when the inter-vehicle distance L is in the safety zone (S5: No), S1 to S5 are repeatedly executed without any warning being notified. Is done. By the way, when the inter-vehicle distance L is equal to or less than the warning distance A (S5: Yes), the seat belt 21 of the retractor 25 is vibrated by repeatedly driving the drive motor 26 at normal speed and reverse at a minute interval. (S6). At this time, if another vehicle is approaching the rear center of the host vehicle 1 (S7: Yes), the W vibrating body 15 sets the drive gain G to “G0” and the drive cycle T to “T0”. (S8).
[0042]
  That is, as shown in FIG. 12, the drive cycle T0 is about 2 seconds, and the drive gain G is G0 and the vibration period is periodically repeated as “Beep, Beep, Beep, Beep, ...”. The That is, it is possible to recognize that another vehicle is approaching behind the host vehicle 1 by the vibration of the W vibrating body 15. Further, since the W vibrating body 15 actually vibrates after the warning is issued through the vibration of the seat belt 21 of the seat belt retractor 25, the surprise and uncomfortable feeling of the driver can be realized with a simple mechanism and with the notice. Can be relaxed.
[0043]
  Next, when the traveling state of the host vehicle 1 is changed based on the vehicle speed signal, a process of changing the vibration mode (drive mode) of the drive gain G of the W vibrating body 15 according to the change is executed ( S9). That is, in this drive mode change processing, the drive gain G of the W vibrating body 15 is driven slightly weaker than the gain G0 (Δ) in the acceleration state, and slightly less than the gain G0 in the deceleration state ( Driven by being enhanced by Δ). On the other hand, when the vehicle speed returns from the acceleration state or the deceleration state to the steady state, the vehicle returns to the original drive gain G0 and is driven.
[0044]
  Next, the detection signals of the detection sensors 4 to 6 are read (S10), and the inter-vehicle distance L between the left rear, the right rear, and the rear center is again calculated (S11). Next, when the inter-vehicle distance L becomes smaller than the previous distance (S12: Yes), the drive gain G is slightly increased by (Δ) (S13). That is, as shown in FIG. 13, the driving gain G is increased as the inter-vehicle distance L decreases. Next, when an operation for avoiding a collision with a vehicle approaching rearward by depressing the accelerator pedal and accelerating the host vehicle 1 or turning the steering wheel to the left or right is performed ( S17: Yes), the drive gain G is reduced to, for example, half the magnitude (S18), and S9 and subsequent steps are repeatedly executed.
[0045]
  On the other hand, when the inter-vehicle distance L becomes larger than the previous time (S12: No), the drive gain G is slightly weakened by (Δ) (S14). Next, the relative speed is obtained, and the alarm distance A is again calculated (S15). When the inter-vehicle distance L is still less than or equal to the alarm distance A (S16: Yes), S17 and subsequent steps are executed. Is larger than the alarm distance A and the safety zone is reached (S16: No), the driving of the vibrators 13 to 15 currently being driven is stopped (S26), and the process returns to S1.
[0046]
  For example, as shown in FIG. 14A, when another vehicle 36 suddenly approaches the rear of the host vehicle 1 while traveling on a general road, the inter-vehicle distance L between the host vehicle 1 and the rear vehicle 36 thereof. Is smaller than the alarm distance A obtained by calculation, the seat belt 21 of the seat belt retractor 25 vibrates, and the W vibrating body 15 is actually vibrated after the vibration of the vibrating body is notified. And it drives so that the drive gain G of the W vibrating body 15 becomes large, so that the distance L between the vehicles becomes small. On the other hand, when a collision avoidance operation such as depressing the accelerator pedal and accelerating or changing the lane to the right or left lane by turning the steering wheel to the right or left, W vibration When the drive gain G of the body 15 is halved and the distance is greater than the alarm distance A, the drive is stopped.
[0047]
  By the way, when the inter-vehicle distance L is equal to or less than the warning distance A (S5: Yes), it is detected based on the steering angle signal that the steering wheel has been rotated to the right, and the host vehicle 1 is moving rightward. (S19: Yes), when another vehicle is approaching the right rear of the host vehicle 1 (S20: Yes), the R vibrating body 13 sets the drive gain G to “G0” and sets the drive cycle T to “ It is driven under the driving condition of “T0” (S21). On the other hand, when the steering wheel is turned counterclockwise, it is detected based on the steering angle signal, and when the host vehicle 1 is moving to the left (S19: No, S22: Yes), another vehicle is the host vehicle 1. When the vehicle is approaching the left rear side (S23: Yes), the L vibrating body 14 is driven under a driving condition in which the driving gain G is set to “G0” and the driving cycle T is set to “T0” (S24). .
[0048]
  Then, during this traveling, when the traveling state is changed based on the steering angle signal, a process of changing the vibration mode of the R vibrating body 13 or the L vibrating body 14 according to the change is executed (S25), S10. The subsequent steps are executed. That is, in this vibration mode changing process, when the R vibrating body 13 is driven in the right turn state, the drive gain G is driven with a gain slightly increased (Δ) from the drive gain G0. Alternatively, when the L vibrating body 14 is driven, the drive gain G is driven with a gain slightly weaker than the drive gain G0 by (Δ).
[0049]
  Conversely, when the R vibrator 13 is driven in the left turn state, the drive gain G is driven with a gain slightly weaker (Δ) than the drive gain G0, or the L vibrator. When 14 is being driven, the drive gain G is driven with a gain that is slightly higher than the drive gain G0 by (Δ). By the way, when returning to the straight traveling state, the driven R vibrating body 13 or L vibrating body 14 returns to the original drive gain G0 and is driven.
[0050]
  For example, as shown in FIG. 14B, when the host vehicle 1 changes the lane to the right traveling lane by rotating the handle to the right, the vehicle 1 and the other vehicle 36 that approaches the rear right side of the vehicle 1 suddenly approach. When the inter-vehicle distance L is smaller than the alarm distance A, the seat belt 21 of the seat belt retractor 25 vibrates, so that the vibration of the vibrating body is informed before the R vibrating body 13 is actually vibrated. And it drives so that the drive gain G of the R vibrating body 13 becomes large, so that the distance L between the vehicles becomes small. On the other hand, when a collision avoidance operation such as depressing the accelerator pedal for acceleration or changing the lane to the original travel lane by turning the steering wheel counterclockwise is performed, the drive gain G of the R vibrator 13 is halved. When the distance is greater than the alarm distance A, the driving is stopped.
[0051]
  Further, as shown in FIG. 14C, when the host vehicle 1 changes the lane to the left traveling lane by rotating the handle to the left, the vehicle 1 and the other vehicle 36 approaching the rear left side of the vehicle 1 suddenly approach. When the inter-vehicle distance L is less than the warning distance A, the seat belt 21 of the seat belt retractor 25 vibrates, so that the L vibrator 14 is actually vibrated after the vibration of the vibrator is notified. And it drives so that the drive gain G of the L vibrating body 14 may become large, so that the distance L between the vehicles becomes small. On the other hand, when a collision avoidance operation such as depressing the accelerator pedal to accelerate or changing the lane to the original travel lane by rotating the steering wheel to the right, the drive gain G of the L vibrator 14 is halved. When the distance is greater than the alarm distance A, the driving is stopped.
[0052]
  Next, a parking notification control routine that is executed when the vehicle 1 is parked in a state where the vehicle speed of the host vehicle 1 is slower than, for example, 30 km / hour will be described based on the flowcharts of FIGS.
  When the ignition switch is operated to start the engine and the shift shift enters the forward or reverse position, this control is started. First, based on the speed signal, when the host vehicle 1 is stopped, S30 is repeated. When it is executed and starts moving (S30: No), detection signals output from the five detection sensors 2 to 6 are read (S31), and based on these detection signals, left front, right front, left rear, The distance L between obstacles between the host vehicle 1 and the obstacle at the right rear and rear center is obtained by calculation (S32).
[0053]
  Next, when all the distances L between the obstacles in these five directions are larger than a predetermined danger distance D (for example, about 1 m) (S33: No), S30 to S33 are repeatedly executed. However, when any one of the distances L between the five obstacles is less than or equal to the predetermined danger distance D (S33: Yes), the drive motor 26 is repeatedly driven at high speeds in normal rotation and reverse rotation every minute time. As a result, the seat belt 21 of the retractor 25 is vibrated (S34).
[0054]
  At this time, when the vehicle is moving backward based on the shift position signal (S35: Yes), if the obstacle is approaching the rear center of the host vehicle 1 (S36 / S38: No), the W vibrating body 15 is driven under a driving condition in which the driving gain G is set to “G0” and the driving cycle T is set to “T0” (S40). Further, when the obstacle is approaching the right rear side of the host vehicle 1 (S36: Yes), the R vibrating body 13 and the W vibrating body 15 set the drive gain G to “G0” and the drive cycle T. When the vehicle is driven at the same time under the driving condition of “T0” (S37) and the obstacle is approaching the left rear of the host vehicle 1 (S36: No, S38: Yes), the L vibrating body 14 and the W The vibrating body 15 is simultaneously driven under the driving condition in which the driving gain G is “G0” and the driving cycle T is “T0” (S39).
[0055]
  On the other hand, when the vehicle is moving forward (S35: No), if the obstacle is approaching the right front of the host vehicle 1 (S41: Yes), the R vibrating body 13 sets the drive gain G to “G0”. And the driving cycle T is set to “T0” (S42), and when the obstacle is approaching the left front of the host vehicle 1 (S41: No), the L vibrating body 14 is Then, the driving is performed under the driving condition where the driving gain G is “G0” and the driving cycle T is “T0” (S43). Next, the detection signals from the five detection sensors 2 to 6 are read again (S44), and the distance L between the obstacles in these five directions is again calculated (S45).
[0056]
  Next, when the host vehicle 1 is moving in the forward or reverse direction (S46: No), and then when the inter-vehicle distance L becomes smaller than the previous time (S47: Yes), it is shown in FIG. As described above, the drive gain G is slightly increased by (Δ) (S48). Next, when the obstacle approaches forward while moving forward, or when the obstacle approaches backward while moving backward, the direction opposite to the direction in which the brake pedal was operated or the obstacle was detected When an operation for avoiding a collision with an approaching obstacle by turning the handle is performed (S50: Yes), the drive gain G is reduced to, for example, half (S51). .
[0057]
  Next, when the shift shift position is other than neutral (N) or parking (P) and the host vehicle 1 moves in the forward direction or the reverse direction (S52: No), S44 and subsequent steps are repeatedly executed. Here, also when the vehicle is stopped with the shift shift in the forward position or the reverse position (S46: Yes), the drive gain G is reduced to about half (S51). By the way, since the own vehicle 1 can be parked in a predetermined parking lot, when the shift shift position is set to neutral (N) or parking (P) (S52: Yes), any vibrator 13 that has been driven is used. ˜15 is stopped (S53), and the process returns to S30.
[0058]
  Here, as shown in FIG. 10, when the parking notification control is partially changed and an obstacle approaches the front, a brake operation is required to increase the distance to the obstacle. Therefore, while driving the brake pedal side, that is, the L vibrating body 14, when an obstacle approaches rearward, an accelerator operation is required to increase the distance between the obstacle and the accelerator pedal. Alternatively, the R vibrating body 13 may be driven.
  That is, S60 to S64 are the same as S30 to S34 of the parking notification control shown in FIG.
[0059]
  When the obstacle is approaching in front of the host vehicle 1 (S65: Yes), the L vibration body 14 on the brake pedal side, that is, the left side, sets the drive gain G to “G0” and sets the drive period T to Driving is performed under a driving condition of “T0” (S66), and S44 and subsequent steps are executed. In addition, when the obstacle is approaching the rear of the host vehicle 1 (S65: No), the R vibrating body 13 has a driving condition in which the driving gain G is set to “G0” and the driving cycle T is set to “T0”. (S39), and similarly S44 and subsequent steps are executed. In this case, it is possible to instruct the driver which one of the brake pedal and the accelerator pedal should be operated via the R vibrating body 13 and the L vibrating body 14, thereby preventing erroneous operation of the pedal operation by the driver. it can.
[0060]
  Next, an emergency vehicle notification control routine for detecting and notifying an approach of an emergency vehicle such as an ambulance or a patrol car will be described based on the flowchart of FIG. This control is executed when the vehicle speed is, for example, 30 km / hour or more and the host vehicle 1 is traveling. However, it is assumed that various siren recognition patterns described later are stored in the ROM 33 in advance.
  When this control is started, an audio signal output from the mylophone 30 is first read (S70), and this audio signal is analyzed (S71).
[0061]
  That is, in this audio signal analysis processing, various noises and noises, wind noises and engine sounds, and various sounds such as vehicle horns are output in a mixed state from the mylophone 30 during traveling. In a wide variety of sounds, it is analyzed whether or not the siren recognition pattern of emergency vehicles (“Peepy Peep” for ambulances, “Woo” for patrol cars, “Ukankan” for fire engines, etc.) When the “siren” is not detected (S72: No), or when the sound level of the “siren” is lower than the predetermined sound pressure P, that is, when the emergency vehicle is traveling far from the own vehicle 1 (S73). : No), S70 to S73 are repeatedly executed.
[0062]
  Then, when a “siren” that substantially matches the siren recognition pattern of the emergency vehicle is detected (S72: Yes) and the sound level of the “siren” is equal to or higher than a predetermined sound pressure P (S73: Yes), the R vibrator 13 The L vibrating body 14 and the W vibrating body 15 are simultaneously driven under the driving conditions in which the driving gain G is set to “G0” and the driving cycle T is set to “T0” (S74). Next, the audio signal from the mylophone 30 is read again (S75), and the audio signal analysis process is executed as in S71 (S76). As a result, when the current sound level is higher than the previous sound level, that is, when the emergency vehicle is approaching the host vehicle 1 (S77: Yes), the drive gain G of the vibrators 13 to 15 is increased. It is slightly strengthened by (Δ) (S78).
[0063]
  And, for example, when an emergency car goes away through the side of the own vehicle 1, the current voice level is lower than the previous voice level (S77: No), but still more than the position to be wary of When approaching and greater than a predetermined sound level (S79: No), the drive gain G of the vibrating bodies 13 to 15 is slightly weakened (Δ) (S80), and S75 to S80 are repeatedly executed. By the way, when the emergency vehicle is far away from the own vehicle 1 and the current sound level is reduced to a predetermined sound level (S79: Yes), the driving of all the vibrators 13 to 15 is stopped ( The process proceeds to S81) and S70.
[0064]
  Here, the left front detection sensor 2 and the right front detection sensor 3 correspond to a pair of left and right front obstacle detection means, and the left rear detection sensor 4 and the right rear detection sensor 5 detect a pair of left and right rear obstacles. The rear center detection sensor 6 corresponds to a rear center obstacle detection means. Further, the retractor 25 that winds up the seat belt 21, the drive motor 26 that rotationally drives the retractor 25, and the like are vibration adding means, and the vibration adding means corresponds to the notice means.
[0065]
  As described above, the R vibrating body 13 and the L vibrating body 14 are provided in the left and right parts different from each other on the seat cushion 11 of the driver seat 10, and the W vibrating body 15 is provided at the center in the width direction of the seat back 12 of the driver seat 10. During driving, the W vibrating body 15 is driven when another vehicle approaches the rear of the own vehicle 1 to be closer to the alarm distance A, and the right side of the own vehicle 1 is changed when the lane is changed to the right running lane. When another vehicle approaches behind the warning distance A, the R vibrating body 13 is driven, and when changing to the left traveling lane, the other vehicle is behind the warning distance A when the vehicle 1 changes to the left side. Since the L vibrating body 14 is driven when approaching near, any one of these vibrating bodies 13 to 15 vibrates as long as the driver sits on the seat 10 in any posture. The direction in which the vehicle is approaching, can be notified to effectively and reliably driver by the position of the vibrator 13 to 15. In addition, passengers listening to radio broadcasts and music will not be disturbed at all.
[0066]
  On the other hand, when the host vehicle 1 is parked in the parking lot, the R vibrating body 13 is driven when an obstacle approaches right front during forward movement, and the L vibrating body 14 is driven when approaching left front, The R vibrating body 13 and the W vibrating body 15 are driven when approaching the right rear, the L vibrating body 14 and the W vibrating body 15 are driven when approaching the left rear, and further, the W vibration is driven when approaching the rear center. Since the body 15 is driven, similarly, as long as the driver sits on the seat 10 in any posture, any of these vibrating bodies 13 to 15 vibrate alone or in combination, so that an obstacle or other The direction in which the vehicle is approaching can be effectively and reliably notified to the driver by the positions of the vibrating bodies 13 to 15. In addition, passengers listening to radio broadcasts and music will not be disturbed at all.
[0067]
  In addition, since the seat belt 21 of the retractor 40 is vibrated before the vibrating bodies 13 to 15 corresponding to the obstacle detection direction are driven, the driving of the vibrating bodies 13 to 15 is notified to the driver. Even a driver who is unfamiliar with the vibration of the seat 10 can alleviate the surprise and uncomfortable feeling when the vibrating bodies 13 to 15 vibrate by the advance notice.
  Moreover, since the drive gain G of the vibrating bodies 13 to 15 to be driven is strengthened as the distance from the own vehicle 1 to the obstacle or other vehicle becomes smaller, the degree of approach of the obstacle or other vehicle is increased. It is possible to effectively notify.
[0068]
  The direction in which an obstacle or other vehicle is detected in consideration of the driver's body swinging in the front-rear direction or the left-right direction according to the traveling state of the host vehicle 1 such as decelerating, accelerating, or turning. Since the drive mode is changed by increasing or decreasing the drive gain G of the vibrators 13 to 15 that are driven corresponding to the vibration, the magnitude of the vibration transmitted to the driver becomes substantially constant, and the obstacle The detection direction can be always stabilized and notified.
  In addition, when an obstacle is detected, when the accelerator pedal or the brake pedal is depressed or the steering wheel is operated so as to avoid a collision with the obstacle, the driving gain of the vibrating bodies 13 to 15 being driven Therefore, the driver's unpleasant sensation can be alleviated.
[0069]
  Further, as shown in FIG. 10, when the obstacle detection direction is the front, the L vibration body 14 on the brake pedal side is driven, while when the obstacle detection direction is the rear, the R vibration body 13 on the accelerator pedal side is driven. Therefore, it is possible to instruct the driver which one of the brake pedal and the accelerator pedal should be operated via the R vibrating body 13 and the L vibrating body 14 and to prevent erroneous operation of the pedal operation by the driver. .
[0070]
  Next, a modified embodiment in which the embodiment is partially modified will be described.

[0072]
6] The drive gain G0 at the start of driving the vibrating bodies 13 to 15 may be set smaller when traveling on a highway than when traveling on a general road. Moreover, you may make it change the drive pattern of the vibrating bodies 13-15 according to the kind of vehicle which approaches.
7] When any of the steering wheel, the brake, and the accelerator is operated, and the collision avoidance operation with the obstacle including the other vehicle approaching rearward or forward is executed, the vibration bodies 13 to 15 being driven are The drive gain G may be weakened.
8] The vibrating bodies 13 to 15 may be constituted by actuators that generate vibrations electrically such as piezoelectric elements and solenoids.
[0073]
9] When changing the lane from the current driving lane to the right or left driving lane, if the blinker is forgotten to be emitted, a warning or warning may be given by a lamp or buzzer, or the direction of the movement direction operated by the steering wheel. The blinker may be configured to automatically operate.
