Description

  The present invention relates to an apparatus and program for performing control for suppressing damage caused by an inappropriate operation, using, for example, an on-vehicle apparatus installed in a vehicle.

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

JP, 2012-107602, A

  In such a conventional method, it is necessary to newly install a mechanism for detecting an erroneous operation and a mechanism for suppressing damage and damage caused by an erroneous operation in a vehicle. For example, even if the in-vehicle apparatus already installed in the vehicle has a function capable of detecting an erroneous operation, a mechanism for detecting an erroneous operation is newly installed separately from the in-vehicle apparatus, so the installation becomes complicated. In addition, it has a functionally redundant configuration.

  Therefore, an object of the present invention is to provide an apparatus that can be easily installed without the need to install a redundant mechanism, and that can reduce damage caused by improper operation. This object is achieved, for example, by the combination of the features described in the independent claims in the claims. The dependent claims also define, for example, further advantageous embodiments of the invention.

(1) In the device of the present invention, an incorrect operation detection unit that detects an inappropriate operation on a vehicle in which an in-vehicle device is available is detected, and the incorrect operation detection unit detects an inappropriate operation. And a damage suppression control unit that performs control to suppress 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 for use different from the application of the in-vehicle device.

  In this way, it is possible to effectively use the functions of the existing in-vehicle devices, and to introduce a mechanism for suppressing damage caused by improper operation of the vehicle without installing a redundant mechanism. . For example, when the existing in-vehicle apparatus is provided with a detection means that can be used to detect an inappropriate operation, the detection means is diverted to the detection of an inappropriate operation instead of the original purpose of use in the in-vehicle apparatus. The provision of redundant detection means can be avoided. Further, for example, when the existing on-vehicle apparatus includes a mechanism capable of controlling the vehicle speed, the mechanism is used to suppress damage caused by an inappropriate operation instead of the original use purpose of the on-vehicle apparatus. It is possible to avoid providing a similar mechanism redundantly.

  As the "use in in-vehicle apparatus", for example, it may be the original use of the in-vehicle apparatus. For example, in the case where the in-vehicle device is an antitheft device, the application position for preventing theft, for example, in the case where the in-vehicle device is a radar detector, the installation position of a radar type speed measuring device or an automatic speed control device (generally called "Ovis") It may be used to notify the driver of the approach to the vehicle.

  The “different application” may be, for example, an application other than the original application of the on-vehicle apparatus. For example, when the on-vehicle device is an anti-theft device, the anti-theft device is used to detect excessive depression of the accelerator, for example, when the on-vehicle device is a radar detector, the radar detector is detected. It is good to use it for

(2) Preferably, the apparatus according to the present invention may further include an activation control unit that enables functions of the erroneous operation detection unit and the damage suppression control unit when predetermined conditions are satisfied. (3) The predetermined condition may be a state in which the vehicle is traveling slowly or in a stopped state. (4) In this case, the predetermined condition is, for example, that the predetermined time has not elapsed since the door was closed, that the predetermined time has not elapsed since the engine was started, and that the vehicle speed is within the predetermined range. Using at least one of: an engine speed at idling and a throttle opening degree equal to or less than a predetermined value; and a predetermined time has not elapsed from when the shift is moved. It should be judged. In particular, it is preferable to further include an activation control unit that makes the functions of the erroneous operation detection unit and the damage suppression control unit effective only when a predetermined condition is satisfied.

  With such a configuration, when the predetermined condition is not satisfied, it is possible to suppress the damage caused by the inappropriate operation only when the predetermined condition is satisfied while using the in-vehicle device as the original application. For example, when the on-vehicle apparatus is the antitheft device, the predetermined condition is "the vehicle is slowly moving or stopped", and when the condition is not satisfied, the antitheft device is an essential application of the antitheft device. The anti-theft device may be used for the purpose of detecting the excessive depression of the accelerator different from the original application when the predetermined conditions are satisfied. As described above, when the predetermined condition is "the vehicle is in a state of slowing or in a stopped state", the necessity for rapid acceleration or sudden start is low, for example, as in a parking lot. Only in circumstances can we reduce the damage caused by improper operation. It may be determined based on the listed conditions that "the vehicle is in a state of slow travel or in a stopped state". An inappropriate operation in the case where the predetermined condition is "the vehicle is slowly moving or being stopped" may be, for example, an accelerator being depressed excessively.

(5) Preferably, in the device according to the present invention, the activation control unit acquires at least one of the engine speed, the vehicle speed, the throttle opening degree, the gear position, and the door open / closed state from the vehicle side. It may be determined whether a predetermined condition is satisfied. The acquisition from the vehicle side may be performed, for example, by acquiring a signal from a computer on the vehicle side. In particular, it may be acquired from a signal line in the vehicle connected to the vehicle-side computer. It is preferable to use the signal line of the vehicle fault diagnosis connector as a connector in which such a signal line exists. In particular, an apparatus-side connector connectable to a failure diagnosis connector of a vehicle may be provided, and the apparatus-side connector may be inserted into the failure diagnosis connector of the vehicle and acquired. As such a connector, an OBD connector may be used.

  With such a configuration, it is possible to acquire information necessary for determining whether or not a predetermined condition is satisfied from the vehicle side. The activation control unit may, for example, acquire information from the vehicle at predetermined time intervals.

(6) Preferably, in the device according to the present invention, the validation control unit corrects the current position acquired by the position information acquiring function of acquiring the current position of the vehicle and the position information acquiring function based on the map information. The activation control unit may be connected to an apparatus having a function, and may determine that the predetermined condition is satisfied when the current position is other than a road.

  With such a configuration, when the acquired current position is other than a road, it is possible to validate the damage of the erroneous operation detection unit and the damage suppression control unit, and to perform control for suppressing the damage. For example, when the vehicle is equipped with a device having a position information acquisition function such as a navigation device or a radar detection device and a map matching function, the erroneous operation detection unit and the damage suppression control unit only when the acquired current position is other than a road. Control can be enabled to validate the damage and control the damage. It is determined that the predetermined condition is satisfied when, for example, the position of the parking facility registered in the map data or the position of the facility set as the destination is the current position as the position “other than road”. If configured, control can be provided to control damage only in the vicinity of the parking lot or destination where slow travel is required, while avoiding affecting normal driving operations in other situations be able to. The inappropriate operation in this case may be, for example, an accelerator depression.

(7) Preferably, in the device according to the present invention, the validation control unit is connected to an apparatus provided with a barometric pressure detection unit, and the validation control unit determines whether a predetermined condition is satisfied based on a change in the pneumatic pressure. It is good to judge

  With such a configuration, in the case of including an apparatus provided with air pressure detection means, it is possible to determine whether a predetermined condition is satisfied or not based on a change in air pressure. For example, in a place where a sudden change in air pressure occurs by moving up and down the floor, such as in a three-dimensional parking lot, it is possible to execute control to suppress damage by validating damage to the erroneous operation detection unit and the damage suppression control unit. It can be done. The inappropriate operation in this case may be, for example, an accelerator depression.

(8) Preferably, in the device of the present invention, the activation control unit is connected to an apparatus having a camera for photographing the periphery of the vehicle, and the activation control unit uses an image of the periphery of the vehicle photographed by the camera. It is preferable to determine whether predetermined conditions are satisfied by image recognition.

  With such a configuration, whether or not a predetermined condition is satisfied can be determined according to the contents shown in the image obtained by photographing the periphery of the vehicle. For example, when the parking frame of the parking lot appears in the image, it is determined that the predetermined condition is satisfied, and the erroneous operation detection unit and the damage suppression control unit validate the damage and execute control to suppress the damage It can be possible. The inappropriate operation in this case may be, for example, an accelerator depression.

(9) Preferably, in the device of the present invention, the validation control unit is connected to an apparatus provided with a microwave detection unit, and the validation control unit detects an obstacle on the wall by the microwave detection unit. It may be determined that a predetermined condition is satisfied.

  With such a configuration, for example, when there is a wall around the vehicle as in a parking lot, it is determined that the predetermined condition is satisfied, and the erroneous operation detection unit and the damage suppression control unit damage are validated, Control to suppress damage can be made executable. The inappropriate operation in this case may be, for example, an accelerator depression.

  The “predetermined condition” that defines the operation of the validation control unit may be any combination of those listed in (3) to (8) above, or any other combination of these. It may be

(10) Preferably, in the device according to the present invention, the in-vehicle device includes an in-vehicle device OBD connector connected to a vehicle-side OBD connector installed in the vehicle, and the erroneous operation detection unit detects the throttle opening from the in-vehicle device OBD connector It is good to acquire and detect the sudden change of the throttle opening as an inappropriate operation.

  With such a configuration, it is possible to acquire raw information of the throttle opening degree from the vehicle side OBD connector, and it is possible to detect excessive depression of the accelerator or incorrect depression of the brake and the accelerator as an inappropriate operation. The difference between brakes and accelerators is how light the pedal effort is, and it is usually heavier for the brakes. Because of this, if you make a mistake in stepping on the brake and the accelerator while trying to apply the brake suddenly, you may step on the accelerator rapidly and cause collision damage due to an unexpected sudden acceleration. It is particularly effective in detecting missteps.

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

  With such a configuration, it is possible to detect excessive depression of the accelerator or incorrect depression of the brake and the accelerator as improper operation. In particular, if you make a mistake in stepping on the brake and the accelerator while trying to apply the brake suddenly, the throttle pedal may step deeply enough to hit the throttle stopper, which may cause collision damage due to an unexpected rapid acceleration. It is particularly effective in detecting wrong pedaling and acceleration.

(12) Preferably, in the device according to the present invention, the in-vehicle device includes a device including a shock detection unit and a tilt detection unit, and the erroneous operation detection unit indicates that the shock detection unit and the tilt detection unit have run over the obstacle. If detected, it may be detected that an inappropriate operation has been performed.

  With such a configuration, in a vehicle provided with an antitheft device provided with a shock detection means and a tilt detection means, these detection means are diverted to detect riding on an obstacle, and control is performed to suppress damage. Can. It can be detected as an inappropriate operation when riding on a car stop with wrong brake and accelerator strokes in a parking lot. Although the antitheft device normally functions only when the vehicle is parked, the potential function of the in-vehicle device can be made effective by diverting the detection means of the antitheft device to detection of an erroneous operation. Effective in terms of availability. The shock detection means and the inclination detection means are configured to detect that an inappropriate operation such as riding on an obstacle has been performed when shock detection and inclination detection matched with 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 control performed to reduce the vehicle speed, for example, in a vehicle equipped with an on-vehicle device having an idling stop system (14), the damage suppression control unit controls the idling stop system when the erroneous operation detection unit detects an inappropriate operation. You should use it to stop the engine. (15) In a vehicle equipped with an anti-theft device having an immobilizer function, the damage suppression control unit stops the engine using the immobilizer function of the anti-theft device when the erroneous operation detection unit detects an inappropriate operation. You should do it.

  With such a configuration, for example, when an inappropriate operation such as a sudden depression of an accelerator is detected, control is performed to reduce the vehicle speed, and control is performed to suppress damage caused by the inappropriate operation. it 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, throttling the throttle valve butterfly to regulate the intake air amount, reducing the fuel injection amount from the injector, thinning the ignition plug ignition, and the like. It is good to adopt the control which suppresses the output.

(16) Preferably, in the device of the present invention, the damage suppression control unit performs control to notify the driver that an inappropriate operation has been detected when the erroneous operation detection unit detects an inappropriate operation. Good. The method of informing the driver may be, for example, a visual method, an auditory method, a tactile method, and a combination thereof, and may be another method. For example, in (17) a vehicle including an apparatus having a monitor as an on-vehicle apparatus, the damage suppression control unit may perform control to display a warning on the monitor when the erroneous operation detection unit detects an inappropriate operation. In the vehicle in which the navigation device and the radar detector are installed, it is possible to visually notify the driver that there is an inappropriate operation. (18) In a vehicle equipped with an antitheft device having a flash irradiation function that threatens a burglar as an on-vehicle device, the damage suppression control unit controls the flash irradiation when the erroneous operation detection unit detects an inappropriate operation. It is good to do. It is possible to visually notify the driver that there is an inappropriate operation. (19) In a vehicle equipped with an antitheft device having an alarm sound function in the vehicle, the damage suppression control unit warns in the vehicle provided in the antitheft device when the erroneous operation detection unit detects an inappropriate operation. It is better to control the sound. The warning sound may be, for example, a siren sound, a buzzer sound, or a voice. The driver can be aurally informed that an improper operation has been made.

  With such a configuration, it is possible to urge the driver who performed the improper operation to perform the operation to avoid the damage caused by the improper operation. In particular, when the driver is asleep or consciously alert, informing the driver that an inappropriate operation has been detected suppresses the damage or prevents an accident. Is effective. In addition to the above, in a vehicle provided with a mechanism (so-called power seat) capable of adjusting the seat position of the driver's seat by power, the driver's seat may be vibrated to notify the driver.

(20) Preferably, in the device of the present invention, the in-vehicle device is an antitheft device provided with notification means to the surroundings, and the damage suppression control unit is not suitable when the operation error detection unit detects an inappropriate operation. The notification means may be controlled to notify the surroundings that an appropriate operation has been detected.

  With such a configuration, it is possible to alert people around the vehicle to take action to avoid damage caused by improper operation. The method of informing a person around the vehicle may be, for example, a visual method or an audible method. As a visual method, for example, control may be performed such as flashing a hazard lamp, passing a headlight, and the like. In addition, in the method by hearing, it is preferable to perform control such as ringing the horn, ringing the siren in the case of a vehicle equipped with an anti-theft siren, and the like.

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

  According to the program of the present invention, it is possible to effectively use the functions of existing in-vehicle devices, and to introduce a mechanism for suppressing damage caused by improper operation of the vehicle without installing a redundant mechanism. it can. For example, when the existing on-vehicle apparatus includes a detection unit that can be used to detect an inappropriate operation, the detection unit functions to divert the detection not to the intended purpose of the on-vehicle apparatus but to an inappropriate operation. In this way, redundant provision of detection means can be avoided. Also, for example, when the existing on-vehicle apparatus includes a mechanism capable of controlling the vehicle speed, the mechanism is used to suppress damage caused by an inappropriate operation rather than the intended purpose of the on-vehicle apparatus. By doing so, it is possible to avoid providing a similar mechanism redundantly.

  ADVANTAGE OF THE INVENTION According to the electronic device of this invention, it is not necessary to install a redundant mechanism and can provide the apparatus for reducing the damage by the improper operation which can be installed easily and can be provided.

[Activation control]
As described above, the erroneous operation damage control apparatus 10 causes the validation control unit 103 to validate the functions of the erroneous operation detection unit 101 and the damage suppression control unit 102 only when the predetermined condition is satisfied. The predetermined condition may be, for example, "the vehicle is slowly moving or stopped." In this case, a predetermined time (for example, 5 minutes) has not elapsed since the door is closed. A predetermined time (for example, 3 minutes) has not elapsed 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 And at least one of the following: the throttle opening degree is equal to or less than a predetermined value (for example, only at 0%), and the predetermined time (for example, one minute) has not elapsed since the shift was moved. Treat as if the given condition is satisfied.

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.

  In the state where the vehicle 1 is running slowly or stopped, the driver's sudden start may be caused by an inappropriate operation such as a wrong pedaling of the throttle pedal and the brake pedal, and damage such as a collision may occur. The activation control unit 103 enables the functions of the erroneous operation detection unit 101 and the damage suppression control unit 102 while the vehicle 1 is moving slowly or stops, so that the throttle pedal and the brake pedal are incorrectly stepped This makes it possible to detect inappropriate operations and to control damage.

When the radar detector 12 notifies that the current position of the vehicle 1 is outside the road, the validation control unit 103 determines that the predetermined condition is satisfied, and the erroneous operation detection unit 101 and the damage suppression control unit 102 Enable the feature of. If the vehicle 1 is in a place other than the road, there is a high possibility that it is a place where slow traveling such as a parking lot is required, and the driver's intention is unintended due to an improper operation of the throttle pedal and the brake pedal. A sudden start is made, and there is a possibility that an outside such as a collision may occur. The erroneous operation damage control 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 a road, so that the wrong operation of the throttle pedal and the brake pedal It is possible to detect appropriate operation and control to control damage.

  In addition, another example of the predetermined condition is "the change in atmospheric pressure is equal to or more than a predetermined value". When the barometric pressure sensor 1263 included in the radar detector 12 detects a barometric pressure change equal to or more than a predetermined value, the validation control unit 103 determines that the predetermined condition is satisfied, and the erroneous operation detection unit 101 and the damage suppression control unit 102 Enable the feature. A sudden change in atmospheric pressure is likely to be a place where slow travel is required, such as underground parking lots and multilevel parking lots. The erroneous operation damage control device 10 of the present embodiment activates the functions of the erroneous operation detection unit 101 and the damage suppression control unit 102 on the condition that the change in atmospheric pressure is equal to or greater than a predetermined value. This makes it possible to detect inappropriate operations and to control damage.

  Also, another example of the predetermined condition is "the vehicle is in the parking lot". Image recognition is performed using an image of the periphery of the vehicle 1 taken by a camera provided in the drive recorder 13 to recognize a frame line of a parking frame drawn on the ground of the parking lot, a car stop, a gate provided at the entrance of the parking lot, etc. , It is determined that the vehicle 1 is in the parking lot. Other methods of judging a parking lot using images include locations specific to the parking lot, locations where cars are lined, locations where white lines are like grids, locations where rings and stops are lined, progress It is determined that the vehicle 1 is in a parking lot by recognizing a place having a wall in a direction, a place surrounded by a wall in one to three directions, a place having a person in a traveling direction, and the like. The traveling direction is detected based on the gear position. In addition, when a building obstacle such as a wall provided in a parking lot is detected by the proximity sensor 1121 included in the antitheft device 11, it is determined that the vehicle 1 is in the parking lot. In addition, the current position of the vehicle is acquired by the position information acquisition unit 125 (for example, a GPS receiver) included in the radar detector 12, and the vehicle 1 is a parking lot by comparing the current position with map information. To detect. The erroneous operation damage control device 10 of this embodiment activates the functions of the erroneous operation detection unit 101 and the damage suppression control unit 102 in a parking lot where there is a high possibility of damage caused by sudden start. Thus, it becomes possible to detect an inappropriate operation such as a sudden depression of the throttle pedal and control to suppress damage.

  Also, another example of the predetermined condition is "the vehicle is in a parking lot and an obstacle such as a wall is recognized in the forward or reverse 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 validated in a situation where there is a risk of collision or entry to an obstacle such as a wall due to an erroneous throttle operation. .

  When the activation control unit 103 is in the standby state, it is possible to recognize that the standby state is achieved by displaying “system in operation” or the like on the monitor of the in-vehicle device, lighting or blinking the LED lamp.

[Detection of incorrect operation]
As described above, when the function of the erroneous operation detection unit 101 is made effective by the activation control unit 103, the erroneous operation detection unit 101 determines that a signal such as a sensor signal output from the in-vehicle device is used in Are received for use in different applications, and detect improper operation of the vehicle 1 based on the received signals. The erroneous operation detection unit 101 of the present embodiment detects an event that can be inferred that the throttle pedal has been suddenly depressed as an inappropriate operation on 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 apparatus side OBD connector 142, and detects an abrupt change in the throttle opening degree as an inappropriate operation. Specifically, when the amount of depression of the throttle pedal changes rapidly, 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 in-vehicle device-side OBD connector 142, it is not necessary to add a dedicated sensor or switch. Further, the erroneous operation detection unit detects the contact of the throttle pedal with the throttle stopper switch 17 as an inappropriate operation.

  The erroneous operation detection unit 101 uses the shock sensor 1122 and the inclination sensor 1123 included in the antitheft device 11 and detects that the vehicle has run onto an obstacle (for example, an obstacle on the road such as a ring). Detect what has been done. Specifically, when the shock sensor 1122 detects an impact, and immediately after that (for example, within one second after detecting the impact) the inclination sensor detects a change in inclination of the vehicle 1 in which the traveling direction side of the vehicle 1 becomes high It is determined that the vehicle 1 has run over the obstacle and that an inappropriate operation has been performed. Algorithm control using the shock sensor 1122 and the inclination sensor 1123 enables accurate detection of an obstacle in the traveling direction.

  In addition, the erroneous operation detection unit 101 detects that an inappropriate operation has been performed, when the rapid detection in the traveling direction is detected by the acceleration sensor included in the radar detector 12 or the drive recorder 13.

  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, it is possible to enhance the detection accuracy of the inappropriate operation.

[Damage suppression control]
As described above, when the function of the damage suppression control unit 102 is made effective by the activation control unit 103, the damage suppression control unit 102 uses an input signal to the on-vehicle device for an application different from that of the on-vehicle device Send to use, and control in-vehicle devices to suppress damage caused by inappropriate operation.

[Reduction of vehicle speed]
The damage suppression control unit 102 performs control to reduce the vehicle speed when the erroneous operation detection unit detects an event that can be inferred that the throttle pedal has been suddenly depressed as an inappropriate operation on the vehicle 1. Specifically, the damage suppression control unit 102 performs control 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 it becomes easy to stop the engine, but also the engine can be easily restarted and it is easy to return to the normal operation. Further, the damage suppression control unit 102 performs control to reduce the vehicle speed by stopping the engine using the immobilizer function of the antitheft device 11. Specifically, the immobilizer function is activated to cut the ignition (IG) line and force engine stall.

  The control to reduce the vehicle speed as described above can suppress the damage caused by the collision of the vehicle 1 with the surrounding articles.

  Further, the damage suppression control unit 102 performs control to suppress an increase in the engine speed. The damage suppression control unit 102 reduces the discharge amount of fuel injection from the injector to suppress the engine output, closes the throttle valve butterfly to restrict the intake air amount, and suppresses the engine output, and cuts the spark from the spark plug. Control the engine output, etc. It is possible to reduce damage caused by collision with a wall or rushing into a store if the vehicle does not make a sudden start or slow acceleration by suppressing an increase in engine speed and slow acceleration. .

[Notification to the car]
The damage suppression control unit 102 performs control to notify the driver that the improper operation has been detected when the erroneous operation detection unit 101 detects an inappropriate operation. The damage suppression control unit 102 controls the interface unit 123 of the radar detector 12 and the alarm unit 114 of the antitheft device 11 to perform control to notify the driver that an inappropriate operation has been performed. When the radar detector includes a monitor, control is performed to display a warning on the monitor. As a specific example of the warning display, an arrow of a traveling direction and an icon of cross (x) are displayed. Further, a siren, which is an example of an indoor warning sound source such as the indoor siren 1142 of the antitheft device 11, is controlled to control the siren sound in the vehicle 1. Further, the flash light 1141 of the antitheft device 11 is controlled to emit flash light to notify the driver. The illumination of the flash light is performed by lighting and blinking patterns.

  By notifying the driver, it is possible to urge the driver who has performed the inappropriate operation to perform an operation to avoid the damage caused by the inappropriate operation. In particular, when the driver is asleep or consciously alert, informing the driver that an inappropriate operation has been detected suppresses the damage or prevents an accident. 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 driver's seat is driven to vibrate to notify the driver.

[Notification to the outside of the car]
The damage suppression control unit 102 performs control to notify the surroundings of the vehicle 1 that an improper operation has been detected when the erroneous operation detection unit detects an inappropriate operation. By notifying the surroundings of the vehicle, it is possible to alert the people around the vehicle 1 to take action to avoid damage caused by an inappropriate operation. A method of informing a person around the vehicle 1 is a method by visual or a method by hearing. The damage suppression control unit 102 controls the high volume siren 1143 of the antitheft device 11 to emit a high volume siren sound around the vehicle 1 to notify the surrounding people of the occurrence of an inappropriate operation.

  When a predetermined operation is performed, the damage suppression control unit 102 performs control to end the control for suppressing the damage and restore the normal operation state. For example, when the brake pedal is pumped 2-3 times, the normal operation state is restored.

  In addition, when the user does not want to use the erroneous operation damage control device 10, by performing a predetermined operation, without using the erroneous operation damage control device 10, the normal operation according to the driving operation is performed. For example, when the emergency switch is pressed for a long time, the erroneous operation damage control device 10 is turned off. It is effective to provide an operation method for not using the erroneous operation damage control device 10 when sufficient engine output is desired on a level difference or a slope.

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

  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 degree of opening 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 treading mistake 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, etc. as OBD information for self-diagnosis of the vehicle. The OBD information is taken out via the vehicle-side OBD connector 141 and the in-vehicle device-side OBD connector 142, and is input to the treading mistake prevention device 100.

  In addition to the OBD information described above, the treading mistake prevention device 100 enables / disables 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 treading mistake prevention device 100. And the emergency release switch 183 for disabling or releasing the damage control. Further, the treading error prevention device 100 receives an input from the front camera 130 for capturing an image in front of the vehicle and the back camera 131 for capturing an image in rear of the vehicle. In addition, the stepping error prevention device 100 includes various sensors (for example, a shock sensor 1122, an inclination sensor 1123, a microwave, etc.) provided in the existing on-vehicle devices such as the antitheft device 11, the radar detector 12, the drive recorder 13 and the idling stop system 15. It receives an input from a sensor 1121, an immobilizer 113, an atmospheric pressure sensor 1263 and the like. A camera provided in the drive recorder 13 mounted as an on-vehicle device can be diverted or shared for the front camera 130 and the back camera 131 described above.

  The output of the step 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 same. Also, the output of the step error prevention device 100 is connected to and controls the hazard lamp 184 and the horn 185 so as to notify the surroundings with sound and light. Further, the output of the step error prevention device 100 is connected to the monitor screen 127, the speaker 128, and the flash light 129 provided in the vehicle to control the driver and the driver by visual and audio notification. The monitor screen 120, the speaker 121, and the flash light 122 can be diverted or shared by the on-vehicle device such as the radar detector 12 or the like.

  If the current position is determined to be a parking lot using the data of the general road and / or expressway possessed by the radar detector 12, the engine rotation is performed with the butterfly in the throttle body not opening even if the accelerator pedal is suddenly depressed. Apply output restrictions so as not to rise rapidly. As a result, it is possible to reduce gear misplacement and unintended runaway in the parking lot.

  Gear position (for example, drive (D) or reverse (R) when an image such as a wall is recognized in the parking lot and in the forward or reverse direction using images of the drive recorder 13, the front camera 130 and the back camera 131 )), It is judged whether the traveling direction of the vehicle is forward or backward based on the usage condition of the back camera 131, etc., and the engine rotation is not increased even if the accelerator is suddenly depressed in the direction of an obstacle etc. Control to apply

  When it is determined that it is not a road or it is determined that it is a parking lot, at the stage where the gear is mistakenly inserted, a large x (cross) mark is displayed on monitor 127. The driver is notified by notification etc.

  A dangerous drive such as sudden start or sudden stop is detected by an acceleration sensor (G sensor) to judge safe driving, and the judgment result is output via a 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 in a dangerous state, even if the accelerator is depressed according to the level, the time until the accelerator is fully opened is extended to realize a gentle acceleration. In addition, the control level is also changed according to the degree of danger.

  The difference between brakes and accelerators is how light the pedal effort is, and it is usually heavier for the brakes. For this reason, when the driver tries to apply the brake suddenly, if the driver steps on the brake and the accelerator incorrectly, the accelerator may be depressed rapidly and fully, causing a collision damage due to an unexpected rapid acceleration. In order to suppress such damage, it detects the speed and stroke in which the accelerator is depressed and warns of sudden acceleration.

  The erroneous operation damage control device 10 can utilize the present invention for eco-drive, in addition to dangerous erroneous operation such as a wrong step on the throttle pedal 170. For example, it is preferable to control so that the butterfly in the throttle body is not opened even if the accelerator is depressed. As a result, the fuel injection amount of the injector can be reduced and fuel consumption can be suppressed.
