[Detailed description of the invention]

[Field of Industrial Application] The present invention relates to vehicle travel control and is particularly directed to a novel vehicle travel control device suitable for encouraging and customizing the wearing of safety devices such as seat belts. Regarding. [Prior Art] It has been widely known that if a seat belt is fastened while the door is open or closed, passengers will suffer less damage in the event of an accident or other emergency situation. . Therefore, it is preferable for safety to always fasten the seat belt when the door is open or closed. However, the reality is that some passengers sometimes drive without wearing their seatbelts for reasons such as being bothersome or unsightly. One way to deal with this situation from the perspective of automobile hardware is to detect the open or closed state of the door unless the seat belt is fastened (for example, Japanese Patent Laid-Open No. 6
0-115618). [Problems to be Solved by the Invention] However, if a means for detecting the open or closed state of the door is adopted unless the seat belt is fastened, for example, if the passenger removes the seat belt for some reason while driving, In such a case, or if Tg is determined that the safety device is not installed due to a malfunction of the sensor system, there is a possibility that control for disallowing the opening or closing of the door will be executed and a problem will occur.

[Purpose of the invention]

The present invention has been made in view of these problems, and while it is mandatory to wear safety devices such as seat belts when starting a vehicle, it is also mandatory to wear safety devices such as seat belts when the door is open or closed. Vehicle running control that enables each running system to function satisfactorily regardless of the situation, and as a result, achieves a good balance between installing safety devices in case of an emergency and maintaining the function of the door in the open or closed state. The purpose is to provide equipment.

By providing this, the above objective is also achieved.

[Effect]

In the present invention, when the vehicle starts (when one vehicle is stopped and one vehicle speed is below a predetermined value), the open or closed state of the door is detected unless the safety device is installed. In addition, if the vehicle enters the -shift state, for example, if the driver removes the safety device for some reason, or if the sensor system malfunctions, Even if the travel is detected, the control to detect the travel is not executed, and therefore, each travel can be operated normally. In the first invention, this travel is not permitted. Since the cancellation is made until the engine OFF is detected, after the -a drive is started, the control to disallow the drive is not executed until the drive is finished.Furthermore, in the second invention, Since this is the case until the door is opened or the leap is detected, when the driver leaves the driver's seat and sits down again, the request to install the safety device will be prompted again. [Example of actual IM] The drawing below is An embodiment of the present invention will be described in detail based on the following. In this embodiment, a seat belt is adopted as a safety device, and a means for fixing an automatic shift shift lever is used as a means for disallowing travel. An example of a control device for fixing this shift lever is shown in Figs. 2 and 3. This shift lever control device is fixed to the vehicle body 1o, and A detent plate 14 having a positioning hole 12 in which each engagement part for the range or the D range is adjacent to each other in order as part of the circumference, and is rotatably supported by the heavy body 10 about an axis 16, A shift lever 18 that allows selection of neutral, parking, drive, etc. positions of an automatic transmission depending on its position relative to the detent plate 14; and the shift lever 1.
It is provided at the lower end of a bushing rod (not shown) disposed in the interior of the detent plate 14 so as to be freely pushed down by the driver. The guide bin 20 and the shift lever 1

An electromagnetic lock device 32 in which an engagement pin 28 supported on the 0 side can be moved and engaged by electromagnetic force, a shift position sensor 34, a seat belt attachment sensor 36, and a pair of first and second vehicle speed sensors 38. .40, engine 0N
It mainly consists of a microcomputer 42 that receives signals from the 1OFF sensor 41, etc., and controls the TI country locking device 32, and a regulation communication means 43 that notifies the driver that shift regulation is being carried out. ing. The engaging pin 28 of the electromagnetic locking device 32 corresponds to the plate 24 with holes exactly when the shift lever 18 is in the N range position and when the shift lever 18 is in the P range position.
A hole 26, that is, a pressure hole 26N for the N range, is located at a position where it can be engaged.
and a P range regulation hole 26P. The electromagnetic locking device 32 is connected to the vehicle body 1011! a case 29 that is fixed to l and slidably supports the engagement bin 28;
, an electromagnet 30 capable of attracting the engaging pin 28, and an electromagnet 30 that can attract the engaging pin 28, and when the electromagnet 3o is de-energized, the engaging pin 28 is
! [It is composed of a spring 31 that pushes back in the direction away from the f1 stone 30. The shift position sensor 34 is a known sensor that detects the position of the shift lever 18. The seatbelt attachment sensor 36 outputs an on signal when the seatbelt is attached. For example, the seatbelt attachment sensor 36 outputs an on signal when the seatbelt is attached. A device that detects whether or not it has been pulled out may be considered. As the first and second width speed sensors 38.4o, two conventional vehicle speed sensors can be used as they are. That is, an automatic transmission normally includes a first vehicle speed sensor 38 that generates one pulse per revolution of the output shaft used for automatic transmission, and a first vehicle speed sensor 38 that generates four pulses per revolution of the output shaft used for a speedometer. Two systems of vehicle speed sensors, a second vehicle speed sensor and 4o, are provided. In this embodiment, the microcomputer 42
The signal from the always-open vehicle speed sensor 38.40 is input to the 1115th! The vehicle speed is determined based on the signal from the sensor 38, and in the event that a malfunction occurs in the first vehicle speed sensor 38, the information from the second speed sensor 40 is used. The engine ON/OFF
The sensor 41 is a known sensor that determines the operating state of the engine based on the position of the ignition switch 46 and the like. The regulation transmission means 43 includes a synthetic voice generator 1143A that generates synthetic meat such as "Please fasten your seatbelt. 43C. In the figure, 44 is a battery, 48 is a fuse, and 50 is a connecting rod that transmits the movement of the shift lever to a manual valve (not shown).Next, this example!@'s The operation will be explained with reference to the flowchart shown in Fig. 4. At steps 100, 102, and 104, the engine is turned on, the vehicle is stopped, and the shift lever 18 is checked. It is determined whether the position is in either the N range or the P range.
Whether the vehicle is stopped or not is determined by whether the signal from the vehicle speed sensor 38 is below a predetermined value! gi. Specifically, for example, if the speed is 6 km/hr or less, it is determined that the vehicle is stopped. If a negative determination is made in any one of the three conditions: the engine is ON, the vehicle is stopped, and the shift lever is in the P or N range, f! ! Both the magnetic rotor locking device 32 and the control transmission means 43 are turned off and the process returns to step 100. On the other hand, if a YES determination is made in all of steps 100, 102, and 104, the process proceeds to step 106, where it is determined whether or not the seat belt is fastened. If it is determined that the seat belt is not fastened, the process proceeds to step 112 and the FF1L lock device 32 is turned off.
At the same time, the regulation transmission means 43 is turned on in step 114. That is, the microcomputer 4
2, the mm stone 30 of the electromagnetic locking device [32] is energized, and this energization causes the engagement pin 28 to move towards the electromagnet 30.
At this time, the engaging pin 28 and the hole 26 (26N or 26P) of the holed plate 24 engage with each other. As a result, the shift lever 18 is fixed at the current P range or N range position, and cannot be moved to any other range. As long as the engine is ON, the vehicle is stopped, and the shift lever is in the P or N range, the electromagnetic locking device 32 remains ON unless the seat belt is fastened. The control transmission means 43 continues to transmit to the driver that the means for disallowing further travel is in the process of functioning. Eventually, when the seat belt is fastened by the driver, the process proceeds to step 116, where the seat belt lock 32 is turned off, and in step 118, the restriction transmission means 4 is turned off.
3 is also turned off. Thereafter, it is determined in step 120 whether the vehicle has stopped, and if the vehicle is running, it is determined in step 116.11.
The flow of step 8 is repeated, and the driving prohibition means is canceled and the vehicle is stopped. When the vehicle has stopped, the process proceeds to step 122, where it is determined whether the engine is turned off. Step 116.11 again when the engine is ON
8 is l15m satL 'b. If it is set to OFF, just in case, repeat steps 108 and 110 M! OF of 10 Tsuku device 32, OF of 71 transmission 1 means 43
Go back to step 100 where you lightly violate F's 〇-. According to this embodiment, when the seat belt is not fastened, the shift lever 18 is in either the P range or the N range, and the vehicle is stopped, the shift lever 18 is locked, It becomes impossible to move to any other range, and the reason why the shift lever 18 is locked is "Please fasten your seat belt."
This can be communicated to the driver by uttering a synthesized voice such as ``j'', and prompting the driver to fasten the seat belt 18. Further, after starting the -shifting process, steps 116 to 120 are performed.
1 or between steps 116 and 122, the shift lever 18 will be activated even if the seat belt is intentionally removed by the driver or the seat belt sensor 36 malfunctions and is determined to be unfastened.
is not locked, and there are no particular inconveniences in terms of use or running. Furthermore, when determining the P range or N range, the shift lever 18 is configured to be locked only in either the P range or N range position due to the hardware structure, and also in the software routine. Since this is determined in step 104, even if the holed plate 24 is no longer correctly fixed and positioned relative to the shift lever 18 due to damage to the ball 22, for example, when the shift lever 18 is in the D range, The electromagnetic locking device [32] is never turned on. Furthermore, since information from two systems of vehicle speed sensors 38 and 40 is input as the width, reliability is greatly improved. FIG. 5 shows an example of another control flow. Steps 100 to 122 are the same as the previous control flow. In this flow, steps 200 to 206 are provided after step 122, and the following operations are performed. That is, when it is determined in step 122 that the engine is ON, the process proceeds to step 200, and the shift lever 18 is turned on.
It is determined whether or not it is in the P range. If it is determined that the door is in the P range, the process advances to step 206; if it is determined that the door is in the "leap" position, the process returns to step 116; if it is determined that the door is "open", the process advances to step 106. Unless you have to fasten your seat belt again.
W1 magnetic lock device @32 is not turned off. When it is determined in step 200 that the shift lever 18 is in a position other than the P range, the process proceeds to step 202 where it is determined whether the shift lever 18 is in the N range. If the vehicle is not in the N range, the process returns to step 116, and if it is determined that the vehicle is in the N range, the process proceeds to step 204, where the handbrake is turned on.
It is determined whether or not it is. Handbrake is O
If it is set to FF, return to step 116 and turn it ON.
If so, the process proceeds immediately before step 206 and a door opening/closing determination is made. According to this flow, the vehicle is stopped and the shift lever is moved to P as a condition for the vehicle to stop and the shift lever to be activated by detecting that the safety device is not installed again when the vehicle has started driving.
The condition is that the vehicle is in the range and the door is opened, or the vehicle is stopped and the shift lever is in the N range, the handbrake is pulled, and the door is opened.
Compared to the previous control flow, it becomes possible to perform control that is more in line with the riding state of the driver. In addition, in the above embodiment, the means for disallowing travel is as follows:
Although a device was adopted to prevent the shift lever from moving into the driving range, the means for disallowing driving in the present invention is not limited to this (for example, a device that cuts the line pressure of the automatic transmission). , A device that specially releases the frictional engagement device that connects and separates the engine side and the drive width side in an automatic transmission, A device that reduces oil pump discharge of the hydraulic control device of an automatic transmission 5! One that controls the stator angle in the torque converter to prevent torque from increasing, one that applies the brakes to the vehicle when it stops on a slope and specially activates the a position.
Change the friction engagement device of the self-help gearshift to a higher speed side so that sufficient drive torque is not obtained in the light path, stop the engine by cutting the fuel supply, etc., or the wire of the accelerator pedal. Various means are possible, such as fixing the link. In addition to the so-called seatbelt, the safety device may include, for example, an arm or the like that restrains and supports the passenger's body. [Effects of the Invention] As explained above, according to the present invention, it is possible to encourage the installation of safety devices when starting the vehicle, and it is possible to prevent the vehicle from interfering with the driving ability. Excellent effects can be obtained.
