Description

The present invention relates to a device and a program for controlling for suppressing damage caused by improper operation by using, for example, an in-vehicle device installed in a vehicle.

In order to suppress damage and damage caused by erroneous operation of the vehicle, a technique for preventing sudden acceleration of the vehicle caused by accidentally depressing the accelerator pedal has been conventionally developed. For example, Patent Document 1 discloses a technique of controlling a throttle to prevent sudden acceleration when the accelerator pedal is suddenly depressed in a parking lot.

Japanese Unexamined Patent Publication No. 2012-107602

In such a conventional method, it is necessary to newly install a mechanism for detecting an erroneous operation and a mechanism for suppressing damage / damage caused by the erroneous operation in the vehicle. For example, even if an in-vehicle device already installed in the vehicle has a function of detecting an erroneous operation, a new mechanism for detecting an erroneous operation is installed separately from the in-vehicle device, which complicates the installation. At the same time, it has a functionally redundant configuration.

Therefore, an object of the present invention is to provide a device for reducing damage caused by improper operation, which can be easily installed without the need to install a redundant mechanism. This object is achieved, for example, by combining the features described in the independent terms in the claims. Dependent terms also define, for example, further advantageous embodiments of the present invention.

(1) The apparatus of the present invention has an erroneous operation detection unit that detects an improper operation on a vehicle in which an in-vehicle device is installed so that it can be used, and an erroneous operation detection unit that detects an improper operation when the erroneous operation detection unit detects the improper operation. It is equipped with a damage control control unit that controls to control the damage caused by the operation. Then, at least one of the erroneous operation detection unit and the damage suppression control unit transmits or receives an input signal to the in-vehicle device or an output signal from the in-vehicle device so as to be used for a purpose different from the use in the in-vehicle device.

In this way, the functions of the existing in-vehicle device can be effectively used, and a mechanism for suppressing damage caused by improper operation of the vehicle can be introduced without installing a redundant mechanism. .. For example, when an existing in-vehicle device is provided with a detection means that can be used to detect an inappropriate operation, the detection means can be diverted to detect an inappropriate operation instead of the original purpose of use in the in-vehicle device. It is possible to avoid providing duplicate detection means. Further, for example, when the existing in-vehicle device is provided with a mechanism capable of controlling the vehicle speed, the mechanism is used not for the original purpose of use of the in-vehicle device but for suppressing damage caused by improper operation. It is possible to avoid duplicating similar mechanisms.

The "use in the in-vehicle device" may be, for example, the original use of the in-vehicle device. For example, when the in-vehicle device is an anti-theft device, it is used to prevent theft. It is good to use it to inform the driver of the approach to.

The "different use" may be, for example, a use other than the original use of the in-vehicle device. For example, when the in-vehicle device is an anti-theft device, the anti-theft device is used to detect excessive depression of the accelerator. For example, when the in-vehicle device is a radar detector, the radar detector is used to detect that the vehicle position is a parking lot. It is good to use it for.

(2) It is preferable that the apparatus of the present invention further includes an activation control unit that activates the functions of the erroneous operation detection unit and the damage suppression control unit when the predetermined conditions are satisfied. (3) The predetermined condition is that the vehicle is driving slowly or stopped. (4) In this case, the predetermined conditions are, for example, that the predetermined time has not passed since the door was closed, that the predetermined time has not passed since the engine was started, and that the vehicle speed is within the predetermined range. , The engine speed is the idling speed, the throttle opening is less than or equal to the predetermined value, and the predetermined time has not passed since the shift was moved, using at least one of them. It should be judged. In particular, it is preferable to further provide an activation control unit that enables the functions of the erroneous operation detection unit and the damage control control unit only when the predetermined conditions are satisfied.

With such a configuration, it is possible to suppress damage caused by improper operation only when the predetermined conditions are satisfied, while using the in-vehicle device for the original purpose when the predetermined conditions are not satisfied. For example, when the in-vehicle device is an anti-theft device, the predetermined condition is "the vehicle is driving slowly or stopped", and when this condition is not satisfied, the anti-theft device is the original use of the anti-theft device. Therefore, when the anti-theft device is satisfied, the anti-theft device may be used for the purpose of detecting the excessive depression of the accelerator, which is different from the original use. In this way, when the predetermined condition is "the vehicle is driving slowly or stopped", the need for sudden acceleration or sudden start is low, for example, when the vehicle is in a parking lot. Only in situations can the damage caused by improper operation be suppressed. It is advisable to judge "the vehicle is driving slowly or stopped" based on the conditions listed. When the predetermined condition is "the vehicle is driving slowly or stopped", the inappropriate operation may be, for example, excessive depression of the accelerator.

It may be connected to a device having a function, and the activation control unit may determine that a predetermined condition is satisfied when the current position is other than the road.

With such a configuration, when the acquired current position is other than the road, it is possible to enable the erroneous operation detection unit and the damage suppression control unit damage and execute the control for suppressing the damage. When the vehicle is equipped with a device having a position information acquisition function and a map matching function such as a navigation device or a radar detection device, the erroneous operation detection unit and the damage control control unit are limited to the case where the acquired current position is other than the road. It is possible to enable control to enable damage and control damage. As the position of "other than the road", for example, when the position of the parking lot facility registered in the map data or the position of the facility set as the destination is the current position, it is judged that the predetermined condition is satisfied. When configured, control can be performed to control damage only in parking lots or near destinations where slowing is required, while avoiding affecting normal driving operations in other situations. be able to. Inappropriate operation in this case may be, for example, excessive depression of the accelerator.

(7) Preferably, in the apparatus of the present invention, the activation control unit is connected to a device provided with an atmospheric pressure detecting means, and whether or not the activation control unit satisfies a predetermined condition based on a change in atmospheric pressure. You should judge.

For example, in a place such as a multi-storey car park where a sudden change in atmospheric pressure occurs when going up and down the floor, it is possible to enable damage to the erroneous operation detection unit and damage control control unit and execute control to suppress the damage. Can be. Inappropriate operation in this case may be, for example, excessive depression of the accelerator.

(8) Preferably, in the device of the present invention, the activation control unit is connected to a device having a camera that captures the periphery of the vehicle, and the activation control unit uses an image of the periphery of the vehicle captured by the camera. It is advisable to judge whether or not the predetermined conditions are satisfied by the image recognition.

With such a configuration, it is possible to determine whether or not a predetermined condition is satisfied according to the content of the photographed image of the periphery of the vehicle. For example, when the parking frame of the parking lot is shown in the image, it is judged that the predetermined conditions are satisfied, the erroneous operation detection unit and the damage control control unit are enabled, and the control for suppressing the damage is executed. It can be possible. Inappropriate operation in this case may be, for example, excessive depression of the accelerator.

(9) Preferably, in the apparatus of the present invention, the activation control unit is connected to a device provided with microwave detecting means, and the activation control unit detects an obstacle on the wall by the microwave detecting means. It may be judged that the predetermined conditions are satisfied.

With such a configuration, when there is a wall around the vehicle, for example, in a parking lot, it is determined that the predetermined conditions are satisfied, and the erroneous operation detection unit and the damage suppression control unit damage are enabled. It is possible to execute control for suppressing damage. Inappropriate operation in this case may be, for example, excessive depression of the accelerator.

The "predetermined condition" that defines the operation of the activation control unit may be any combination of those listed in (3) to (8) above, or a combination of these and other conditions. It may be.

(10) Preferably, in the device of the present invention, the in-vehicle device includes an on-board device side OBD connector connected to the vehicle side OBD connector installed in the vehicle, and the erroneous operation detection unit has a throttle opening degree from the in-vehicle device side OBD connector.

With such a configuration, it is possible to acquire raw information on the throttle opening degree from the vehicle-side OBD connector, and it is possible to detect excessive depression of the accelerator or mistaken depression of the brake and accelerator as inappropriate operations. The difference between the brake and the accelerator is whether the pedaling force is light or heavy, and the brake is usually heavier. For this reason, if you make a mistake in stepping on the brake and accelerator when trying to apply a sudden brake, you may suddenly step on the accelerator and cause collision damage due to unexpected sudden acceleration. It is especially effective in detecting missteps.

(11) Preferably, in the device of the present invention, the in-vehicle device includes a contact detecting means provided on the throttle stopper, and the erroneous operation detecting unit may detect the contact of the throttle pedal with the detecting means as an inappropriate operation.

With such a configuration, it is possible to detect excessive depression of the accelerator or mistaken depression of the brake and accelerator as inappropriate operations. In particular, if you make a mistake in pressing the brake and accelerator when trying to apply a sudden brake, the throttle pedal may be depressed deep enough to hit the throttle stopper, causing collision damage due to unexpected sudden acceleration. It is especially effective in detecting mistakes in stepping on the accelerator.

(12) Preferably, in the apparatus of the present invention, the in-vehicle device includes a device including a shock detecting means and a tilt detecting means, and the erroneous operation detecting unit rides on an obstacle by the shock detecting means and the tilt detecting means.

With such a configuration, in a vehicle equipped with an anti-theft device equipped with a shock detecting means and an inclination detecting means, these detecting means are diverted to detect climbing on an obstacle and control for suppressing damage. Can be done. If you make a mistake in stepping on the brake and accelerator in the parking lot and get on the car stop, it can be detected as an inappropriate operation. The anti-theft device normally functions only when the vehicle is parked, but by diverting the detection means of the anti-theft device to detect an erroneous operation, the potential function of the in-vehicle device can be effectively utilized. It is effective in that it can be used. The shock detecting means and the tilt detecting means are configured to detect that an inappropriate operation such as riding on an obstacle has been performed when the shock detection and the tilt detection matching a predetermined sequence are performed. It is good to do.

(13) Preferably, in the device of the present invention, the damage suppression control unit may perform control to reduce the vehicle speed when the erroneous operation detection unit detects an inappropriate operation. As a control to reduce the vehicle speed, for example, (14) In a vehicle equipped with an in-vehicle device having an idling stop system, the damage control control unit controls the idling stop system when an erroneous operation detection unit detects an inappropriate operation. Use it to stop the engine. (15) In a vehicle equipped with an anti-theft device having an immobilizer function, the damage control control unit stops the engine by using the immobilizer function of the anti-theft device when the erroneous operation detection unit detects an inappropriate operation. It is good to let it.

With such a configuration, when an improper operation such as a sudden depression of the accelerator is detected, it is possible to control to reduce the vehicle speed and control the damage caused by the improper operation. can. In particular, the vehicle can be suddenly stopped by forcibly stopping the engine by the idling stop system or the immobilizer function. Other controls to reduce the vehicle speed include, for example, throttle valve butterfly to regulate the intake air amount, reduce the amount of fuel injection discharged from the injector, and thin out the ignition of the spark plug. It is advisable to adopt a control that suppresses the output.

The method of notifying the driver may be, for example, a visual method, an auditory method, a tactile method, and a combination thereof, or may be another method. For example, (17) In a vehicle equipped with a device having a monitor as an in-vehicle device, the damage control control unit may control to display a warning on the monitor when the erroneous operation detection unit detects an inappropriate operation. In a vehicle equipped with a navigation device or a radar detector, it is possible to visually notify the driver that an improper operation has been performed. (18) In a vehicle equipped with an anti-theft device having a flash irradiation function that threatens a thief as an in-vehicle device, the damage control control unit controls to irradiate the flash when an erroneous operation detection unit detects an inappropriate operation. It is good to do. It is possible to visually notify the driver that an improper operation has been performed. Further, (19) In a vehicle equipped with an anti-theft device having a function of sounding a warning sound in the vehicle, the damage control control unit warns the inside of the vehicle equipped with the anti-theft device when an erroneous operation detection unit detects an inappropriate operation. It is good to control the sound. The warning sound may be, for example, a siren sound, a buzzer sound, a voice, or the like. It is possible to aurally notify the driver that an improper operation has been performed.

With such a configuration, it is possible to encourage a driver who has performed an improper operation to perform an operation for avoiding damage caused by the improper operation. In particular, when the driver is dozing or unconscious, notifying the driver that an inappropriate operation has been detected can suppress damage and prevent accidents. Is effective. In addition to the above, in a vehicle provided with a mechanism (so-called power seat) that can adjust the seat position of the driver's seat by power, it is preferable to drive the driver's seat so as to vibrate and notify the driver.

(20) Preferably, in the device of the present invention, the in-vehicle device is an anti-theft device provided with a means for notifying the surroundings, and the damage control control unit is not suitable when the erroneous operation detection unit detects an inappropriate operation.

The method of notifying people around the vehicle may be, for example, a visual method or an auditory method. As a visual method, for example, it is preferable to perform control such as blinking a hazard lamp or passing a headlight. Further, in the auditory method, it is preferable to control the horn, or in the case of a vehicle equipped with a siren for theft prevention, the siren.

(21) In order to solve the above problems, in the program of the present invention, it is preferable to make the computer function as any of the above-mentioned devices.

[Activation control]
As described above, the erroneous operation damage suppression device 10 enables the functions of the erroneous operation detection unit 101 and the damage suppression control unit 102 described above by the activation control unit 103 only when the predetermined conditions are satisfied. The predetermined condition may be, for example, "the vehicle is slowing down or stopped". In this case, the predetermined time (for example, 5 minutes) has not passed since the door was closed. A predetermined time (for example, 3 minutes) has not passed since the engine was started, the vehicle speed is within a predetermined range (for example, 0 km / hour to 5 km / hour), and the engine speed is the idling speed. At least one of the above, that the throttle opening is less than or equal to the predetermined value (for example, only at 0%), and that the predetermined time (for example, 1 minute) has not passed since the shift was moved was satisfied. In some cases, it is treated as satisfying the predetermined conditions.

Determine if it is. By acquiring the vehicle information from the vehicle side OBD connector 141, it is not necessary to add a dedicated sensor or switch.

When the vehicle 1 is slowing down or stopped, the driver may make an unintended sudden start due to an inappropriate operation such as a mistake in pressing the throttle pedal and the brake pedal, which may cause damage such as a collision. However, when the vehicle 1 is slowing down or stopped, the activation control unit 103 enables the functions of the erroneous operation detection unit 101 and the damage suppression control unit 102, so that the throttle pedal and the brake pedal are pressed incorrectly.

Enable the function of. The fact that the vehicle 1 is in a place other than the road is likely to be a place where slow driving is required, such as a parking lot, and the driver does not intend due to an inappropriate operation such as a mistake in pressing the throttle pedal and the brake pedal. There is a possibility that the vehicle will start suddenly and will be exposed to collisions. Since the erroneous operation damage suppression device 10 of the present embodiment activates the functions of the erroneous operation detection unit 101 and the damage suppression control unit 102 on condition that the current position is other than the road, there is no mistake of depressing the throttle pedal and the brake pedal. It is possible to detect appropriate operations and control to suppress damage.

Another example of the predetermined condition is "the change in atmospheric pressure is equal to or greater than the predetermined value". When the atmospheric pressure sensor 1263 included in the radar detector 12 detects a change in atmospheric pressure of a predetermined value or more, the activation control unit 103 determines that the predetermined conditions are satisfied, and the erroneous operation detection unit 101 and the damage suppression control unit 102 Enable the function. Sudden changes in atmospheric pressure are likely to be places where slowing is required, such as underground parking lots and multi-storey car parks. Since the erroneous operation damage suppression device 10 of the present embodiment activates the functions of the erroneous operation detection unit 101 and the damage suppression control unit 102 on condition that the change in atmospheric pressure is equal to or higher than a predetermined value, the throttle pedal and the brake pedal are erroneously pressed. It is possible to detect inappropriate operations and control to suppress damage.

Another example of the predetermined condition is "the vehicle is in the parking lot". Image recognition is performed using the image of the surroundings of the vehicle 1 taken by the camera provided in the drive recorder 13, and the frame line of the parking frame drawn on the ground of the parking lot, the car stop, the gate provided at the entrance of the parking lot, etc. are recognized. , Determines that vehicle 1 is in the parking lot. Other methods of determining a parking lot using images include places where cars are lined up, places where white lines are like a grid, places where wheel chocks and bollards are lined up, and progress, which are peculiar to parking lots. It is determined that the vehicle 1 is in the parking lot by recognizing a place where there is a wall in the direction, a place where the walls are surrounded in the 1st to 3rd directions, a place where a person is in the traveling direction, and the like. The traveling direction is detected based on the gear position. Further, when the proximity sensor 1121 provided in the anti-theft device 11 detects a building obstacle such as a wall provided in the parking lot, it is determined that the vehicle 1 is in the parking lot. Further, by acquiring the current position of the vehicle by the position information acquisition unit 125 (for example, GPS receiver) included in the radar detector 12 and collating the current position with the map information, the vehicle 1 can be identified as a parking lot. To detect. Since the erroneous operation damage suppression device 10 of the present embodiment activates the functions of the erroneous operation detection unit 101 and the damage suppression control unit 102 in a parking lot where damage is likely to occur due to a sudden start, the throttle pedal and the brake pedal are erroneously pressed. It is possible to detect improper operation such as sudden depression of the throttle pedal due to such factors, and to control to suppress damage.

Another example of the predetermined condition is that "the vehicle is in the parking lot and an obstacle such as a wall is recognized in the forward or backward direction of the vehicle". Under such conditions, the functions of the erroneous operation detection unit 101 and the damage suppression control unit 102 can be enabled in a situation where there is a risk of collision or rushing into an obstacle such as a wall due to an erroneous throttle operation. ..

When the activation control unit 103 is in standby mode, it is possible to recognize that the system is in standby mode by displaying "system is operating" or the like on the monitor of the in-vehicle device, lighting or blinking the LED lamp, or the like.

[Detection of erroneous operation]
When the function of the erroneous operation detection unit 101 is enabled by the activation control unit 103 as described above, the erroneous operation detection unit 101 uses a signal such as a sensor signal output from the in-vehicle device as an application in the in-vehicle device. Receives for different purposes and detects improper operation on vehicle 1 based on the received signal. The erroneous operation detection unit 101 of the present embodiment detects an event that can be presumed that the throttle pedal has been suddenly depressed as an inappropriate operation for the vehicle 1.

The erroneous operation detection unit 101 acquires the throttle opening degree from the vehicle side OBD connector 141 via the in-vehicle device side OBD connector 142, and detects a sudden change in the throttle opening degree as an inappropriate operation. Specifically, when the amount of depression of the throttle pedal changes suddenly, such as from 0% to 100%, it is detected as an inappropriate operation. By acquiring vehicle information from the vehicle-side OBD connector 141 via the vehicle-mounted device-side OBD connector 142, it is not necessary to add a dedicated sensor, switch, or the like. Further, the erroneous operation detection unit detects the contact of the throttle pedal with the throttle stopper switch 17 as an inappropriate operation.

When the erroneous operation detection unit 101 uses the shock sensor 1122 and the inclination sensor 1123 included in the anti-theft device 11 to detect that the vehicle has climbed onto an obstacle (for example, a road obstacle such as a wheel chock), an inappropriate operation is performed. Detect what has been done. Specifically, when the shock sensor 1122 detects an impact and immediately after that (for example, within 1 second after detecting the impact), the inclination sensor detects a change in the inclination of the vehicle 1 in which the traveling direction side of the vehicle 1 becomes higher. In addition, it is determined that the vehicle 1 has climbed onto an obstacle and it is detected that an improper operation has been performed. By algorithmic control using the shock sensor 1122 and the tilt sensor 1123, it is possible to accurately detect an obstacle in the traveling direction.

In addition, the erroneous operation detection unit 101 detects that an improper operation has been performed when the acceleration sensor included in the radar detector 12 or the drive recorder 13 detects a sudden acceleration in the traveling direction.

The erroneous operation detection unit 101 may detect an inappropriate operation based on any combination of the plurality of methods described above. By combining a plurality of conditions, the detection accuracy of improper operation can be improved.

[Damage control control]
When the function of the damage suppression control unit 102 is enabled by the activation control unit 103 as described above, the damage suppression control unit 102 sends the input signal to the in-vehicle device to an application different from the application in the in-vehicle device. It transmits for use and controls in-vehicle devices to suppress damage caused by improper operation.

[Reduction of vehicle speed]
The damage suppression control unit 102 controls to reduce the vehicle speed when the erroneous operation detection unit detects an event that can be presumed that the throttle pedal has been suddenly depressed as an inappropriate operation for the vehicle 1. Specifically, the damage suppression control unit 102 controls to reduce the vehicle speed by stopping the engine using the idling stop system 15. When the idling stop system 15 is used, not only the engine can be easily stopped, but also the engine can be easily restarted and the normal operation can be easily returned. Further, the damage control control unit 102 controls to reduce the vehicle speed by stopping the engine by using the immobilizer function of the anti-theft device 11. Specifically, the immobilizer function is activated to cut the ignition (IG) line and force the engine to stall.

By the control for reducing the vehicle speed as described above, it is possible to suppress the damage caused by the vehicle 1 colliding with the surrounding articles.

In addition, the damage suppression control unit 102 controls to suppress an increase in the engine speed. The damage control control unit 102 reduces the discharge amount of fuel injection from the injector to suppress the engine output, closes the throttle valve butterfly to regulate the intake air amount to suppress the engine output, and cuts sparks from the spark plug. Controls such as suppressing engine output. If the increase in engine speed is suppressed and the vehicle does not start suddenly, or if the vehicle accelerates slowly, damage can be reduced if the vehicle collides with a wall or the like or the vehicle rushes into the store. ..

[Notification to the inside of the car]
When the erroneous operation detection unit 101 detects an improper operation, the damage suppression control unit 102 controls to notify the driver that the improper operation has been detected. The damage control control unit 102 controls the interface unit 123 of the radar detector 12 and the alarm unit 114 of the anti-theft device 11 to notify the driver that an inappropriate operation has been performed. If the radar detector is equipped with a monitor, it controls to display a warning on the monitor. As a specific example of the warning display, an arrow in the direction of travel and an icon of × (cross mark) are displayed. In addition, a siren, which is an example of an indoor warning sound source such as the indoor siren 1142 of the anti-theft device 11, is controlled to make a siren sound in the vehicle 1. In addition, the flash light 1141 of the anti-theft device 11 is controlled to irradiate the flash light to notify the driver. The flash light is irradiated according to the lighting or blinking pattern.

By notifying the driver, it is possible to urge the driver who has performed an improper operation to perform an operation for avoiding damage caused by the improper operation. In particular, when the driver is dozing or unconscious, notifying the driver that an inappropriate operation has been detected can suppress damage and prevent accidents. Is effective. In addition to the above, in the vehicle 1 provided with a mechanism (so-called power seat) capable of adjusting the seat position of the driver's seat by power, the vehicle 1 is driven so as to vibrate the seat of the driver's seat to notify the driver.

[Notification to the outside of the vehicle]
When the erroneous operation detection unit detects an improper operation, the damage suppression control unit 102 controls to notify the surroundings of the vehicle 1 that the improper operation has been detected. By notifying the surroundings of the vehicle, it is possible to alert people around the vehicle 1 and encourage them to take actions to avoid damage caused by improper operation. The method of notifying the people around the vehicle 1 is a visual method or an auditory method. The damage control control unit 102 controls the loud siren 1143 of the anti-theft device 11 to emit a loud siren sound around the vehicle 1 to notify the surrounding people of the occurrence of an inappropriate operation.

The damage suppression control unit 102 controls to end the control for suppressing damage and return to the normal operating state when a predetermined operation is performed. For example, when the brake pedal is pumped 2-3 times, it returns to the normal operating state.

Further, when the erroneous operation damage suppressing device 10 is not desired to be used, a predetermined operation is performed so that the erroneous operation damage suppressing device 10 is not used and the normal operation according to the driving operation is performed. For example, the erroneous operation damage suppression device 10 is configured to be turned off when the emergency switch is pressed and held for a long time. When a sufficient engine output is desired on a step or a slope, it is effective to provide an operation method for not using such an erroneous operation damage suppressing device 10.

[Specific application example]
FIG. 5 is a configuration diagram showing an example in which the stepping error prevention device 100, which is an example of the erroneous operation damage suppressing device 10, is applied to the vehicle 1. The vehicle 1 includes a throttle pedal 170 which is an input means for controlling the vehicle speed by an operation by the driver, and the throttle sensor 171 detects the amount of depression of the throttle pedal 170. A throttle stopper switch 17 is provided at a position where the back surface of the pedal comes into contact when the throttle pedal 170 is fully depressed, and it is detected that the throttle pedal 170 is fully depressed by the throttle stopper switch 17.

The amount of depression detected by the throttle sensor 171 is transmitted to the engine ECU 16 via the throttle controller 160. The throttle controller 160 defines the correspondence between the amount of depression of the throttle pedal 170 and the opening degree of the throttle valve 161. Further, the output signal of the throttle sensor 171 branches from the path to the throttle controller 160 and is also input to the stepping error prevention device 100. The engine ECU 16 controls the intake air amount of the throttle valve 161, the fuel injection amount of the injector 162, the ignition timing of the spark plug 163, and the like based on the output of the throttle controller 160.

The engine ECU 16 outputs vehicle speed, engine speed, throttle opening, gear position, brake switch information, and the like as OBD information for self-diagnosis of the vehicle. These OBD information is taken out via the vehicle side OBD connector 141 and the vehicle-mounted device side OBD connector 142, and is input to the stepping error prevention device 100.

In addition to the above-mentioned OBD information, the stepping error prevention device 100 enables / disables the functions of the door switch 180 for detecting the opening and closing of the door, the ignition (IG) switch 181 for starting the engine of the vehicle, and the stepping error prevention device 100. Receives input from the ON / OFF switch 182 for switching, the emergency release switch 183 for disabling or canceling the damage suppression control, and the like. Further, the stepping error prevention device 100 receives inputs from the front camera 130 for capturing an image in front of the vehicle and the back camera 131 for capturing an image in the rear of the vehicle. Further, the stepping error prevention device 100 includes various sensors (for example, shock sensor 1122, tilt sensor 1123, microwave) provided in existing in-vehicle devices such as the anti-theft device 11, radar detector 12, drive recorder 13, and idling stop system 15. The input from the sensor 1121, the immobilizer 113, the pressure sensor 1263, etc.) is received. For the front camera 130 and the back camera 131 described above, the camera included in the drive recorder 13 mounted as an in-vehicle device can be diverted or shared.

The output of the stepping error prevention device 100 is connected to a path connecting the throttle sensor 171 and the engine ECU 16, and controls the throttle controller 160 and the engine ECU 16 via the throttle controller 160. Further, the output of the stepping error prevention device 100 is connected to a hazard lamp 184 and a horn 185 to notify the surroundings by sound and light, and controls them. Further, the output of the stepping error prevention device 100 is connected to a monitor screen 127, a speaker 128, and a flashlight 129 provided in the vehicle to notify the driver visually and audibly, and controls them. As the monitor screen 120, the speaker 121, and the flashlight 122, those provided by an in-vehicle device such as a radar detector 12 can be diverted or shared.

Using the data of the general road and / or highway of the radar detector 12, when the current position is determined to be a parking lot, the engine rotates in a direction that does not open the butterfly in the throttle body even if the accelerator is suddenly depressed. The output is limited so that it does not rise rapidly. As a result, it is possible to reduce misplacement of gears and unintended runaway in the parking lot.

When an obstacle such as a wall is recognized in the parking lot and in the forward or reverse direction using the images of the drive recorder 13 and the front camera 130 and the back camera 131, the gear position (for example, drive (D) or reverse (R)) is recognized. ) Or), it is determined whether the vehicle is moving forward or backward based on the usage status of the back camera 131, and even if the accelerator is suddenly depressed in the direction of an obstacle, the engine rotation is not increased or the output is limited. Control to apply.

If it is judged to be other than the road or the parking lot, when the gear is put in by mistake, a large x (x) mark is displayed on the monitor 127, a warning sound is emitted, a flash is emitted, and the vibration motor 186 is vibrated. Notify the driver by notifying the driver.

The acceleration sensor (G sensor) detects dangerous driving such as sudden start and stop, judges safe driving, and outputs the judgment result via the character displayed on the screen (for example, animation of "Kirishima Rei"). When the radar detector 12 is provided, if the character determines that the vehicle is driving dangerously, even if the accelerator is depressed according to the level, the time until the accelerator is fully opened is lengthened to realize gentle acceleration. The control level is also changed according to the degree of danger.

The difference between the brake and the accelerator is whether the pedaling force is light or heavy, and the brake is usually heavier. For this reason, if the brake and the accelerator are mistakenly depressed when trying to apply the brake suddenly, the accelerator may be suddenly depressed to the full extent, causing collision damage due to unexpected sudden acceleration. In order to suppress such damage, the speed and stroke of depressing the accelerator are detected, and a warning of sudden acceleration caution is given.

The erroneous operation damage suppressing device 10 can be utilized for eco-driving, in addition to dangerous erroneous operations such as a mistake in stepping on the throttle pedal 170. For example, it is preferable to control the butterfly in the throttle body so that it does not open even if the accelerator is depressed. As a result, the fuel injection amount of the injector can be reduced and the fuel consumption can be suppressed.
