Description

The present invention relates to an accelerator abnormality operation determination system, and more specifically, to an accelerator abnormality operation determination system for determining an abnormality operation of an automobile accelerator pedal.

Conventionally, in driving a car, the accelerator pedal is operated by the driver. The accelerator pedal is usually operated according to the driver's intention to accelerate or decelerate the vehicle, but in some cases, the driver unintentionally operates the accelerator pedal to suddenly accelerate (runaway) the vehicle. In some cases.

In order to prevent such an unintended operation of the accelerator pedal by the driver, for example, the accelerator pedal is provided, the depression speed of the accelerator pedal is detected, and it is determined whether or not there is an abnormality in the depression operation of the accelerator pedal. When there is an abnormality, the sensor switch that outputs an abnormality signal, receives the abnormality signal from the sensor switch, transmits the control signal to the brake that controls the engine refueling, shuts off a large amount of refueling operation, and refuels a small amount. When the control unit that maintains the normal operation of the engine and the release unit, which are provided on the shift lever, detect the position of the shift lever and put the shift lever in the P range (parking) or N range (neutral). As the release unit, a vehicle runaway prevention device including a release unit that transmits a release signal to the control unit to release the control signal has been proposed (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2019-26254

In the above-mentioned vehicle runaway prevention device, the abnormality of the accelerator pedal depression operation is determined based only on the accelerator pedal depression speed.

On the other hand, the accelerator pedal of an automobile may be depressed relatively quickly even during normal driving. In particular, in a relatively small vehicle such as a light vehicle, the accelerator pedal is depressed relatively quickly during normal driving such as when starting, traveling on a slope, or after a curve.

However, the above-mentioned vehicle runaway prevention device has a problem that even in such a normal running, if the accelerator pedal is depressed relatively quickly, it is determined as an abnormality in the operation.

The present invention is an accelerator abnormal operation determination system capable of determining an abnormal operation of the accelerator pedal with higher accuracy.

The present invention [1] is an accelerator abnormal operation determination system for determining an abnormal operation of an accelerator pedal of an automobile, and is an operation speed detecting means for detecting the operating speed of the accelerator pedal and a traveling state detecting means for detecting the traveling state of the automobile. And an abnormality determining means for determining an abnormal operation of the accelerator pedal, the traveling state detecting means includes an accelerator opening detecting means for detecting the accelerator opening at the start of operation of the accelerator pedal and a vehicle speed detecting means for detecting the vehicle speed. The abnormality determination means includes a threshold value calculation unit that calculates a threshold value of the operation speed of the accelerator pedal based on the accelerator opening degree and the vehicle speed, and the operation speed of the accelerator pedal detected by the operation speed detection means. Includes an accelerator abnormality operation determination system including a determination unit for determining that the accelerator pedal is abnormally operated when the threshold value is equal to or higher than the above threshold value.

In the present invention [2], the traveling state detecting means further includes a load detecting means for detecting a load of an automobile, and the threshold value calculating unit of the abnormality determining means is based on an accelerator opening degree, a vehicle speed, and a load. The accelerator abnormality operation determination system according to the above [1] is included, which calculates the threshold value of the operation speed of the accelerator pedal.

In the accelerator abnormality operation determination system of the present invention, the threshold value of the operation speed of the accelerator pedal is calculated based on the accelerator opening degree at the start of operation of the accelerator pedal and the vehicle speed.

Then, in the accelerator abnormality operation determination system of the present invention, when the operation speed of the accelerator pedal is equal to or more than the calculated threshold value, it is determined that the accelerator pedal has been abnormally operated.

Therefore, according to the accelerator abnormality operation determination system of the present invention, the abnormality operation of the accelerator pedal can be accurately determined according to the traveling state of the automobile.

FIG. 2 is an example of a flowchart for determining an abnormal operation of the accelerator pedal. FIG. 3 is a schematic configuration diagram showing another embodiment (a mode without a load sensor) of the accelerator abnormality operation determination system of the present invention. FIG. 4 is a schematic configuration diagram showing another embodiment (a mode including an exception control unit) of the accelerator abnormality operation determination system of the present invention.

1. 1. Overall Configuration of Accelerator Abnormal Operation Judgment System In FIG. 1, the determination system 1 as an accelerator abnormal operation determination system is a system for determining an abnormal operation of an accelerator pedal (not shown (the same applies hereinafter)) of an automobile 10.

The abnormal operation of the accelerator pedal is an operation of the accelerator pedal that is not intended by the driver, and indicates an operation that causes a runaway of the automobile, such as an erroneous start of the automobile 10 or an erroneous acceleration of the automobile 10.

The determination system 1 includes an operation detection unit 2 as an operation speed detecting means, a traveling detection unit 3 as a traveling state detecting means, and an abnormality determining unit 4 as an abnormality determining means.

The operation detection unit 2 is a device for detecting the operation speed (depression speed) of the accelerator pedal.

The operation detection unit 2 is not particularly limited, and examples thereof include a known pedal sensor. The pedal sensor can detect the operating speed (depressing speed) of the accelerator pedal based on, for example, the arrangement of the accelerator pedal (pedal angle) and the change in the arrangement.

The travel detection unit 3 is a device for detecting the travel state of the automobile 10.

The traveling state of the automobile 10 includes, for example, the vehicle speed of the automobile 10, the accelerator opening degree of the automobile 10, and the load capacity of the automobile 10.

More specifically, the travel detection unit 3 includes an accelerator opening degree sensor 31 as an accelerator opening degree detecting means, a vehicle speed sensor 32 as a vehicle speed detecting means, and a load sensor 33 as a load detecting means.

The accelerator opening sensor 31 is a sensor for detecting the accelerator opening at the start of operation of the accelerator pedal. The accelerator opening sensor 31 is not particularly limited, and a known accelerator opening sensor can be used. For example, examples of the accelerator opening sensor 31 include a sensor that predicts the accelerator opening based on the position of the accelerator pedal.

Such an accelerator opening sensor 31 monitors, for example, the amount of change in the accelerator opening, and sets the accelerator opening when the amount of change becomes a negative value as a reference value (stepping start opening (zero change)). Set as. Further, when the change amount of the accelerator opening becomes positive at the start of the operation of the accelerator pedal, the change amount is continuously recorded as the accelerator opening degree (accelerator opening degree data). As a result, the accelerator opening sensor 31 can detect the accelerator opening at the start of operation of the accelerator pedal.

Such an accelerator opening sensor 31 is electrically connected to a threshold value calculation unit 41 (described later) of the abnormality determination unit 4.

As a result, the accelerator opening sensor 31 can input the accelerator opening data as an electric signal into the threshold calculation program P1 (described later) of the threshold calculation unit 41 (see the broken line in FIG. 1).

The vehicle speed sensor 32 is a sensor for detecting the speed (vehicle speed) of the automobile 10. The vehicle speed sensor 32 is not particularly limited as long as it can detect the speed of the automobile 10, and a known speed sensor can be used.

The vehicle speed sensor 32 may detect the speed of the automobile 10 from, for example, the number of rotations of the tires, or acquire the position data of the automobile 10 using, for example, a GPS system, and obtain the position data of the automobile 10 from the change of the position data. The moving speed of the automobile 10 may be calculated.

As a result, the vehicle speed sensor 32 can continuously acquire the speed (speed data) of the automobile 10.

Such a vehicle speed sensor 32 is electrically connected to a threshold value calculation unit 41 (described later) of the abnormality determination unit 4.

As a result, the vehicle speed sensor 32 can input the speed data of the automobile 10 as an electric signal into the threshold value calculation program P1 (described later) of the threshold value calculation unit 41 (see the broken line in FIG. 1).

The load sensor 33 is a sensor for detecting the load of the automobile 10.

The load capacity indicates, for example, the weight of an animal (including a person), a luggage, or the like loaded on the automobile 10.

The load sensor 33 is not particularly limited as long as it can detect the load, and a known load sensor can be used. As a result, the load sensor 33 can continuously acquire the value (load data) of the load of the automobile 10.

Such a load sensor 33 is electrically connected to a threshold value calculation unit 41 (described later) of the abnormality determination unit 4. As a result, the load sensor 33 can input the load data of the automobile 10 into the threshold value calculation program P1 (described later) of the threshold value calculation unit 41 as an electric signal (see the broken line in FIG. 1).

The abnormality determination unit 4 is a device for determining an abnormality operation of the accelerator pedal based on the traveling state of the automobile 10.

More specifically, the abnormality determination unit 4 is a control unit (that is, an Electronic Control Unit) that executes electrical control in the automobile 10, and is composed of a microcomputer including a CPU, a ROM, a RAM, and the like. There is.

Further, the abnormality determination unit 4 determines whether or not the accelerator pedal is abnormally operated based on the threshold value calculation unit 41 that calculates the threshold value (described later) of the operation speed of the accelerator pedal and the threshold value (described later). It is provided with a part 42.

The threshold value calculation unit 41 is a unit that calculates the operation speed (that is, the threshold value) of the accelerator pedal as a reference in determining the abnormal operation of the accelerator pedal.

More specifically, the threshold value calculation unit 41 is electrically connected to the accelerator opening sensor 31, the vehicle speed sensor 32, and the load sensor 33, respectively (see the broken line in FIG. 1). As a result, the accelerator opening data detected by the accelerator opening sensor 31, the vehicle speed data detected by the vehicle speed sensor 32, and the load data detected by the load sensor 33 are transferred to the threshold value calculation unit 41, respectively. , It is possible to input as an electric signal.

Then, the threshold value calculation unit 41 includes a threshold value calculation program P1 for calculating the threshold value.

In the threshold value calculation program P1, if the operating speed (depressing speed) of the accelerator pedal is, the operation is as intended by the driver (that is, normal operation), and the operating speed (depressing speed) of the accelerator pedal is It is a program that determines a reference operation speed (threshold value) as to how much the operation is not intended by the driver (that is, an abnormal operation).

More specifically, in the determination system 1, when the operation speed (depression speed) of the accelerator pedal is higher than the threshold value, it is determined that the operation is not intended by the driver (that is, an abnormal operation).

On the other hand, for example, when the vehicle speed of the automobile 10 is relatively low, the accelerator operation speed (depression speed) becomes high even in the normal acceleration operation. That is, when the vehicle speed is relatively low, it is possible that the accelerator is vigorously operated (depressed) for the acceleration of the automobile 10. On the other hand, when the vehicle speed of the automobile 10 is relatively high, it is rare that the accelerator is operated (stepped on) more vigorously.

That is, the threshold value of the accelerator operation speed for determining that the operation is not intended by the driver (that is, an abnormal operation) differs depending on the vehicle speed of the automobile 10.

Similarly, when the accelerator opening degree is relatively small, the accelerator operation speed (depression speed) becomes high even in a normal acceleration operation. That is, when the accelerator opening degree at the start of the accelerator operation is relatively small, the accelerator may be vigorously operated (depressed) for the acceleration of the automobile 10. On the other hand, when the accelerator opening at the start of accelerator operation is relatively large, it is rare that the accelerator is operated (depressed) more vigorously.

That is, the threshold value of the accelerator operation speed for determining that the operation is not intended by the driver (that is, an abnormal operation) differs depending on the accelerator opening at the start of the accelerator operation.

Further, for example, when the load capacity of the automobile 10 is relatively large, the accelerator operation speed (depression speed) becomes high even in the normal acceleration operation. That is, when the load capacity of the automobile 10 is relatively large, the accelerator may be vigorously operated (depressed) for the acceleration of the automobile 10. On the other hand, when the load capacity of the automobile 10 is relatively small, it is rare that the accelerator is stepped on more vigorously.

That is, the threshold value of the accelerator operation speed for determining that the operation is not intended by the driver (that is, an abnormal operation) may differ depending on the load of the automobile 10.

As described above, when the accelerator operation speed is relatively high (that is, when the accelerator is stepped on vigorously), the determination of whether the accelerator operation is normal or abnormal is determined by the vehicle speed of the automobile 10 and the start of the accelerator operation. It depends on the accelerator opening, load capacity, etc.

If the threshold value is not changed according to these conditions (vehicle speed of the automobile 10, accelerator opening at the start of accelerator operation, load, etc.), even normal accelerator operation is erroneously determined to be an abnormal operation. In some cases.

Therefore, the threshold value calculation unit 41 includes a threshold value calculation program P1 for calculating the threshold value of the accelerator operation speed based on the vehicle speed of the automobile 10, the accelerator opening at the start of accelerator operation, and the load of the automobile. There is.

Such a threshold value calculation program P1 is not particularly limited, is designed by a known method, and is stored in the threshold value calculation unit 41.

The determination unit 42 is provided to determine that the accelerator pedal is abnormally operated when the operation speed of the accelerator pedal is equal to or higher than the threshold value.

More specifically, the determination unit 42 is electrically connected to the operation detection unit 2 (see the broken line in FIG. 1). As a result, the accelerator operation speed detected by the operation detection unit 2 can be input to the threshold value calculation unit 41 as an electric signal.

Further, the determination unit 42 is electrically connected to the threshold value calculation unit 41 (see the broken line in FIG. 1). As a result, the threshold value calculated by the threshold value calculation unit 41 can be input to the determination unit 42 as an electric signal.

The determination unit 42 is designed so that the detected accelerator operation speed and the calculated threshold value can be compared.

More specifically, the determination unit 42 includes an abnormality determination program P2 for determining an abnormality operation of the accelerator pedal.

The abnormality determination program P2 is a program that determines that the accelerator pedal is abnormally operated when the operation speed of the accelerator pedal detected by the operation detection unit 2 is equal to or greater than the threshold value calculated by the above threshold value calculation program P1. Is.

That is, as will be described in detail later, the abnormality determination program P2 determines whether the accelerator pedal operation speed (depression speed) is the accelerator operation (that is, normal operation) as intended by the driver. , It is possible to determine how much the accelerator pedal operation speed (depression speed) is the accelerator operation (that is, abnormal operation) not intended by the driver.

Such an abnormality determination program P2 is not particularly limited, is designed by a known method, and is stored in the determination unit 42.

In the abnormality determination unit 4, the threshold value calculation unit 41 and the determination unit 42 may be provided independently of each other or integrally.

Further, the determination system 1 is electrically connected to the brake system 5.

The brake system 5 is a system for decelerating or stopping the automobile 10. As the brake system 5, a known brake system is adopted. Further, the brake system 5 can be provided with an indicator control unit that controls an indicator such as a warning light, and can also be provided with an accelerator control unit that controls an accelerator opening degree.

When the determination system 1 determines an abnormal operation of the accelerator pedal, the brake system 5 can input the determination result. Then, when an abnormal operation of the accelerator pedal is determined, the automobile 10 can be decelerated or stopped by the autonomous operation of the brake system 5.

2. Judgment of Abnormal Operation by Judgment System In the following, a method of detecting the operation speed of the accelerator pedal by the judgment system 1 and determining the abnormal operation of the accelerator pedal will be described in detail with reference to FIG.

More specifically, first, at the start of driving the automobile 10, the determination system 1 is started to operate, and the threshold value calculation program P1 and the abnormality determination program P2 are executed (S1: start).

When the determination system 1 starts operating, the threshold value calculation program P1 first calculates a threshold value for determining an abnormal operation of the accelerator pedal (S2).

That is, when the operation of the automobile 10 is started, the accelerator opening sensor 31 continuously detects the accelerator opening, and the accelerator opening data at the start of the accelerator operation is continuously input to the threshold calculation program P1 of the threshold calculation unit 41. do.

Further, the vehicle speed sensor 32 continuously detects the speed (vehicle speed) of the automobile 10, and continuously inputs the vehicle speed data into the threshold value calculation program P1 of the threshold value calculation unit 41.

Further, the load sensor 33 continuously detects the load of the automobile 10, and continuously inputs the load data into the threshold value calculation program P1 of the threshold value calculation unit 41.

Then, the threshold value calculation program P1 determines a threshold value for determining the operation speed of the accelerator pedal as abnormal based on the accelerator opening degree data, the vehicle speed data, and the load data.

More specifically, for example, based on the vehicle speed data, a threshold value for determining the operating speed of the accelerator pedal as abnormal is tentatively determined, and then the tentatively determined threshold value is determined by the accelerator opening degree data and the load data. to correct.

The method of calculating the threshold value is not particularly limited, but for example, by acquiring in advance a correlation map between the opening degree data, the vehicle speed data, and the load data and the accelerator opening degree in abnormal driving, and following the correlation map, the above-mentioned The threshold value of can be easily calculated.

As a result, the threshold value (operation speed) for determining the abnormal operation of the accelerator pedal is calculated. More specifically, for example, when the accelerator opening degree is 5%, the vehicle speed is 10 km / h, and the load is 150 kg, the threshold value of the accelerator operation speed is set to 600% / sec.

Then, the threshold value calculation unit 41 inputs the calculated threshold value (operation speed) into the abnormality determination program P2 of the determination unit 42.

On the other hand, in the determination system 1, the operation detection unit 2 continuously detects the operation speed (depression speed) of the accelerator pedal as the operation of the automobile 10 starts (S3).

Then, the operation detection unit 2 inputs the obtained operation speed (depression speed) of the accelerator pedal into the abnormality determination program P2 of the determination unit 42.

After that, in this determination system 1, the abnormality determination unit 4 executes the abnormality determination program P2 of the determination unit 42, and the operation speed of the accelerator pedal detected by the operation detection unit 2 and the threshold value calculated by the threshold value calculation unit 41. (Operation speed) is compared (S4).

Then, as a result of comparison, when the operating speed of the accelerator pedal is less than the above threshold value (S4: NO), the determination unit 42 determines that the operating speed of the accelerator pedal is appropriate for the running state, and the accelerator pedal. Is determined to be operating normally.

In this case, the traveling of the automobile 10 is continued, and the above processing is continued.

On the other hand, when the operating speed of the accelerator pedal is equal to or higher than the above threshold value (S4: YES), the determination unit 42 determines that the operating speed of the accelerator pedal is excessively high with respect to the running state, and the accelerator pedal is abnormally operated. It is determined that it is.

In this case, the determination unit 42 inputs to the brake system 5 that the accelerator pedal has been abnormally operated, and operates the brake system 5. As a result, the automobile 10 is decelerated or stopped (S5).

After that, the above processing ends (end).

3. 3. Action / Effect In the above determination system 1, the threshold value of the operation speed of the accelerator pedal is calculated based on the accelerator opening at the start of operation of the accelerator pedal, the vehicle speed, and the load.

Then, in the above-mentioned determination system 1, when the operation speed of the accelerator pedal is equal to or higher than the calculated threshold value, it is determined that the accelerator pedal has been abnormally operated.

Therefore, according to the above-mentioned determination system 1, the abnormal operation of the accelerator pedal can be accurately determined according to the traveling state of the automobile 10.

As a result, according to the above-mentioned determination system 1, it is possible to suppress unexpected behavior of the automobile such as erroneous starting and accelerating of the automobile.

4. Modification example In the above description, the travel detection unit 3 includes a load sensor 33, and the threshold value calculation unit 41 (threshold value calculation program P1) of the abnormality determination unit 4 determines the accelerator opening, the vehicle speed, and the load. Although the threshold value of the operation speed of the accelerator pedal is calculated based on this, as shown in FIG. 3, the travel detection unit 3 does not have to include the load sensor 33.

In this case, the threshold value calculation unit 41 (threshold value calculation program P1) of the abnormality determination unit 4 can calculate the threshold value of the operation speed of the accelerator pedal based on the accelerator opening degree and the vehicle speed without referring to the load.

That is, in such a determination system 1, the threshold value of the operation speed of the accelerator pedal is calculated based on the accelerator opening degree at the start of operation of the accelerator pedal and the vehicle speed.

Then, in the above-mentioned determination system 1, when the operation speed of the accelerator pedal is equal to or higher than the calculated threshold value, it is determined that the accelerator pedal has been abnormally operated.

Therefore, even in the above-mentioned determination system 1, the abnormal operation of the accelerator pedal can be accurately determined according to the traveling state of the automobile 10.

As a result, even in the above-mentioned determination system 1, it is possible to suppress unexpected behavior of the automobile such as erroneous starting and accelerating of the automobile.

From the viewpoint of further improving the determination accuracy, the travel detection unit 3 preferably includes a load sensor 33, and the threshold value calculation unit 41 (threshold value calculation program P1) is based on the accelerator opening, the vehicle speed, and the load. , Calculate the threshold value of the operation speed of the accelerator pedal.

Further, the determination system 1 may include an exception control unit 6 as shown in FIG.

The exception control unit 6 is a unit for exceptionally interrupting the operation of the above-mentioned abnormality determination program P2.

That is, as described above, the abnormal operation of the accelerator pedal is determined by comparing the operation speed of the accelerator pedal with the calculated threshold value.

However, depending on the running state of the automobile 10, the operating speed of the accelerator pedal may be higher than the threshold value even in normal driving, which may cause an erroneous judgment.

More specifically, for example, when the automobile 10 travels uphill, the accelerator may be vigorously operated (depressed), so that the operating speed of the accelerator pedal may be higher than the threshold value. be.

Further, for example, even when the automobile 10 decelerates or accelerates after stopping, the accelerator may be vigorously operated (depressed), so that the operating speed of the accelerator pedal may be higher than the threshold value.

Further, for example, when the automobile 10 accelerates after turning right or left at an intersection or the like, the accelerator may be vigorously operated (depressed), so that the operating speed of the accelerator pedal becomes higher than the threshold value. There is.

In these cases, even if the operation is normal, the abnormality determination program P2 may determine that the accelerator pedal is abnormally operated, and the brake system 5 decelerates or stops the automobile 10 to make driving comfortable. Sex may be reduced.

Therefore, in this embodiment, a case where the operation speed of the accelerator pedal is predicted to be relatively high is set in advance as an exceptional state, and it is detected that the exceptional state is applicable, and the exception control unit 6 is used. The operation of the abnormality determination program P2 is interrupted.

More specifically, the exception control unit 6 can include, for example, a vehicle attitude sensor (not shown) for detecting the inclination of the vehicle 10, whereby the vehicle 10 is traveling uphill. It can be detected.

Further, the exception control unit 6 can be provided with, for example, a sensor for detecting the on / off of the stop lamp switch of the automobile 10, whereby it is possible to detect that the automobile 10 has decelerated or stopped.

Further, the exception control unit 6 can be provided with, for example, a sensor for detecting the operation of the blinker of the automobile 10, whereby it can detect that the automobile 10 has turned right or left at an intersection or the like.

Such an exception control unit 6 is electrically connected to the determination unit 42 (see the broken line in FIG. 4), and the operation of the abnormality determination program P2 can be exceptionally interrupted.

More specifically, when the exception control unit 6 detects, for example, that the automobile 10 is traveling uphill, the exception control unit 6 inputs the data to the abnormality determination program P2 and interrupts the operation of the abnormality determination program P2. .. As a result, even when the operation speed of the accelerator pedal becomes higher than the threshold value on an uphill, the automobile 10 can be driven without being determined to be an abnormal operation.

Further, when the exception control unit 6 detects, for example, that the automobile 10 has decelerated or stopped, the data is input to the abnormality determination program P2 to interrupt the operation of the abnormality determination program P2. As a result, even if the operating speed of the accelerator pedal becomes higher than the threshold value after deceleration or stopping, the automobile 10 can be driven without being determined to be an abnormal operation.

Further, when the exception control unit 6 detects, for example, that the automobile 10 has turned right or left at an intersection or the like, the exception control unit 6 inputs the data to the abnormality determination program P2 and interrupts the operation of the abnormality determination program P2. As a result, even if the operating speed of the accelerator pedal becomes higher than the threshold value after turning right or left, the automobile 10 can be driven without being determined to be an abnormal operation.

When the exception control unit 6 detects that the exceptional condition has been resolved, such as the end of an uphill, the exception control unit 6 operates the abnormality determination program P2.

Then, also in such an embodiment, similarly to the above, the threshold value of the operation speed of the accelerator pedal is calculated based on the accelerator opening at the start of operation of the accelerator pedal, the vehicle speed, and (furthermore, the load). ..

Then, in the above-mentioned determination system 1, when the operation speed of the accelerator pedal is equal to or higher than the calculated threshold value, it is determined that the accelerator pedal has been abnormally operated.

Therefore, even in the above-mentioned determination system 1, the abnormal operation of the accelerator pedal can be accurately determined according to the traveling state of the automobile 10.

As a result, even in the above-mentioned determination system 1, it is possible to suppress unexpected behavior of the automobile such as erroneous starting and accelerating of the automobile.

Further, the automobile 10 can be provided with a confirmation device for confirming the operation or stop of the determination system 1 if necessary, and when the determination system 1 is stopped while the automobile 10 is traveling, the automobile 10 is driven. Can be stopped.
