Description

The present invention relates to a control device used in a vehicle equipped with a manual transmission.

In recent years, there have been accidents caused by misapplication of the brake pedal and the accelerator pedal of a vehicle, that is, an accident in which the driver accidentally depresses the accelerator pedal and the brake pedal with the intention of stopping the vehicle, causing the vehicle to accelerate against the driver's will. It is frequent.

Misapplication accidents occur in vehicles equipped with two pedals, an accelerator pedal and a brake pedal (two-pedal vehicle), that is, vehicles equipped with an automatic transmission, and vehicles equipped with three pedals, an accelerator pedal, a brake pedal, and a clutch pedal. (three-pedal vehicles), i.e. vehicles equipped with a manual transmission, are generally considered not to occur.

That is, in a two-pedal vehicle, when the shift range of the automatic transmission is set to the D range (driving range), the engine and drive wheels are connected so as to be able to transmit power. When the accelerator pedal is stepped on, the engine speed increases, the engine output increases, and the vehicle suddenly accelerates, which may cause an accident of colliding with an object in front or behind. On the other hand, in a three-pedal vehicle, when the vehicle is stopped, the clutch pedal is depressed and the engine is disconnected from the drive wheels. It is generally believed that the vehicle does not suddenly accelerate just by going up (raising), so that an accident does not occur.

However, as the inventors of the present application proceeded with research on vehicle safety, it was found that depending on the vehicle conditions, even in a three-pedal vehicle, an accident could occur due to misapplication of the brake pedal and the accelerator pedal.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle control apparatus capable of reducing or suppressing the occurrence of accidents caused by erroneous operation of a brake operation member and an accelerator operation member in a vehicle equipped with a manual transmission. be.

In order to achieve the above object, a vehicle control device according to the present invention includes a drive source, a manual transmission for shifting power from the drive source, and connecting the drive source and the manual transmission by engagement and disengagement. A clutch that disconnects the drive source and the manual transmission by means of a clutch, a brake mechanism that applies braking force to the wheels, and an acceleration operation to increase the output of the drive source and a deceleration operation to decrease the output of the drive source. an accelerator operation member that is operated to increase the braking force of the brake mechanism and is operated to be released to decrease the braking force of the brake mechanism; and an engagement operation member that is operated to engage the clutch. and a clutch operation member that is operated to release the clutch, the control device for releasing the clutch operation member when the degree of acceleration operation of the accelerator operation member is greater than an accelerator reference. Based on the degree, it is determined whether or not to suppress the running of the vehicle by the drive source, and when it is determined to suppress the running of the vehicle, the running of the vehicle is suppressed.

According to this configuration, when the degree of acceleration operation of the accelerator operation member is greater than the accelerator reference, it is determined whether or not to suppress the running of the vehicle by the drive source based on the degree of release operation of the clutch operation member. .

For example, when the vehicle is running (driving idle or under cruise control) with none of the accelerator operating member, brake operating member, or clutch operating member being operated, the red light of the traffic signal in the direction of travel lights up. When the driver misunderstands the braking operation of the brake operation member and performs the acceleration operation of the accelerator operation member, the vehicle is rapidly accelerated because the clutch is engaged. Accidents may occur due to

Therefore, when the degree of acceleration operation of the accelerator operation member is greater than the accelerator reference, and the clutch operation member is not released, or even if the clutch operation member is released, the release operation is performed. If the degree is small and the clutch remains engaged, it may be determined to restrain the vehicle from running. As a result, the running of the vehicle is suppressed, so if the acceleration operation of the accelerator operation member is mistaken for the braking operation of the brake operation member, the damage caused by the operation error is reduced or the occurrence of the accident is suppressed. can do.

On the other hand, even if the degree of acceleration operation of the accelerator operation member is greater than the accelerator reference, the release operation of the clutch operation member is performed in parallel with the acceleration operation of the accelerator operation member. In such a case, it may be determined not to suppress the running of the vehicle. By disengaging the clutch, the drive source and the manual transmission are separated, and even if the output of the drive source increases in accordance with the acceleration operation of the accelerator operating member, the vehicle will not accelerate. can be reduced or the occurrence of accidents can be suppressed.

Moreover, since the vehicle does not accelerate despite the increase in the output of the drive source, it is easy for the driver to notice that the braking operation of the brake operation member has been mistaken for the acceleration operation of the accelerator operation member. Therefore, it can be expected that the acceleration operation of the accelerator operation member will be stopped and the braking operation of the brake operation member will be performed sooner after the occurrence of the operation error. As a result, it is possible to further reduce the damage caused by accidents caused by erroneous operations or to further suppress the occurrence of accidents.

The vehicular control device determines to suppress the running of the vehicle by the drive source when the degree of acceleration operation of the accelerator operation member is greater than the accelerator reference and the degree of release operation of the clutch operation member is equal to or less than the clutch reference. Alternatively, it may be determined not to suppress the running of the vehicle by the drive source when the degree of acceleration operation of the accelerator operation member is greater than the accelerator reference and the degree of release operation of the clutch operation member is greater than the clutch reference.

The vehicle control device may issue a notification when the degree of acceleration operation of the accelerator operation member is greater than the accelerator reference and the degree of release operation of the clutch operation member is greater than the clutch reference.

With this configuration, it is possible to quickly notice that the driver has mistaken the braking operation of the brake operation member for the acceleration operation of the accelerator operation member. As a result, it can be expected that the acceleration operation of the accelerator operation member will be stopped and the braking operation of the brake operation member will be performed sooner after the occurrence of the operation error, thereby further reducing the damage or accidents caused by the operation error. can be further suppressed.

Advantageous Effects of Invention According to the present invention, it is possible to reduce or suppress the occurrence of accidents caused by erroneous operation of the brake operation member and the accelerator operation member.

BEST MODE FOR CARRYING OUT THE INVENTION Below, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

<Vehicle configuration>
FIG. 1 is a diagram showing the configuration of a vehicle 1 employing a vehicle control device according to an embodiment of the invention.

A vehicle 1 is an automobile having an engine (E/G) 2 as a drive source. The engine 2 is provided with an electronic throttle valve for adjusting the amount of intake air into the combustion chamber of the engine 2, an injector (fuel injection device) for injecting fuel into the intake air, and a spark plug for generating electrical discharge in the combustion chamber. It is The engine 2 is also provided with a starter for starting the engine.

A vehicle 1 is equipped with a manual transmission (MT) 3 as a transmission that changes the speed of power from an engine 2 . A clutch 4 for connecting and disconnecting the engine 2 and the manual transmission 3 is interposed between the engine 2 and the manual transmission 3 . With the clutch 4 engaged, the engine 2 and the manual transmission 3 are connected. At this time, the power output from the engine 2 is input to the manual transmission 3 via the clutch 4, shifted by the manual transmission 3, transmitted from the manual transmission 3 to the differential gear 5, and transmitted from the differential gear 5 to the left and right gears. is transmitted to the driving wheels 6 as a driving force for running.

In the passenger compartment of the vehicle 1, at the foot of the driver's seat, there are an accelerator pedal 11 that is operated by the driver to adjust the output of the engine 2, and a braking force that acts on each wheel including the driving wheels 6. and a clutch pedal 13 that is stepped on by the driver to switch between engagement and release of the clutch 4. . The accelerator pedal 11 and the brake pedal 12 are arranged in order from the right side of the vehicle 1 at positions where it is convenient for the driver seated in the driver's seat to step with his right foot. The clutch pedal 13 is spaced to the left from the brake pedal 12 and arranged at a position where it is convenient for the driver seated in the driver's seat to operate the clutch pedal 13 with his left foot.

In addition, the vehicle 1 is equipped with a hydraulic brake mechanism 14 . Brake mechanism 14 includes a brake booster, a master cylinder and a brake actuator. When the brake pedal 12 is stepped on, the force applied to the brake pedal 12 is transmitted to the brake booster. The pedaling force transmitted to the brake booster is amplified (boosted) by the negative pressure of the brake booster and input from the brake booster to the master cylinder. In the master cylinder, hydraulic pressure is generated according to the force input from the brake booster. The hydraulic pressure generated by the master cylinder is transmitted to the brake actuator. By the function of the brake actuator, hydraulic pressure is distributed to the wheel cylinders of the brakes provided on each wheel, and the hydraulic pressure applies braking force to the wheels from each brake.

The clutch 4 employs, for example, a configuration of a dry single plate clutch. That is, the clutch 4 includes a flywheel held by the output shaft of the engine 2, a clutch cover fixed to the flywheel, a diaphragm spring having an outer peripheral portion supported by the clutch cover, and a spring between the flywheel and the diaphragm spring. and a clutch disc disposed between the flywheel and the pressure plate.

When the clutch pedal 13 is not stepped on, the pressing force due to the spring force of the diaphragm spring is input to the pressure plate from the outer peripheral portion of the diaphragm spring, and the pressure plate presses the clutch disc against the flywheel. This state is the engaged state (engaged state) of the clutch 4 , and in the engaged state, the power of the engine 2 is transmitted to the manual transmission 3 via the clutch 4 .

A release bearing is arranged opposite to the inner peripheral portion of the diaphragm spring on the side opposite to the pressure plate side with respect to the diaphragm spring. The clutch pedal 13 is connected to the tip of the piston of the master cylinder. Connected to the master cylinder are a reservoir hose for circulating oil with the reservoir and a clutch pipe for transmitting hydraulic pressure to the release cylinder. When the clutch pedal 13 is depressed, the piston of the master cylinder is pushed by the clutch pedal 13 and hydraulic pressure is generated in the master cylinder. The hydraulic pressure generated by the master cylinder is transmitted to the release cylinder through the clutch piping. The release fork is operated by hydraulic pressure transmitted to the release cylinder, and the release fork presses the release bearing toward the diaphragm spring. This pressing force is input to the inner peripheral portion of the diaphragm spring via the release bearing, causing the diaphragm spring to tilt and elastically deform, thereby canceling the input of the pressing force from the outer peripheral portion of the diaphragm spring to the pressure plate. As a result, the clutch disc is separated from the flywheel. This state is the state in which the clutch 4 is released (disengaged), and the power of the engine 2 is not transmitted to the manual transmission 3 when the clutch 4 is released.

The vehicle 1 is also equipped with a plurality of ECUs (Electronic Control Units). Each ECU has a microcomputer (microcontroller unit), and the microcomputer contains, for example, a CPU, nonvolatile memory such as flash memory, and volatile memory such as DRAM (Dynamic Random Access Memory). A plurality of ECUs are connected so as to be capable of two-way communication using CAN (Controller Area Network) communication protocol. Various sensors necessary for control are connected to each ECU, and detection signals of the connected sensors are input. In addition to detection signals input from various sensors, information necessary for control is input to each ECU from other ECUs.

FIG. 1 shows an ECU 21 for control for reducing damage caused by a collision of the vehicle 1 or avoiding the collision among the plurality of ECUs. An accelerator sensor 22, a brake sensor 23, a clutch stroke sensor 24, a wheel speed sensor 25, a forward detection sensor 26, a steering angle sensor 27, and a gradient sensor 28 are connected to the ECU 21, and detection signals from these sensors are input. be done.

The accelerator sensor 22 outputs a detection signal corresponding to the amount of operation of the accelerator pedal 11 .

The brake sensor 23 outputs a detection signal corresponding to the amount of operation of the brake pedal 12 .

The clutch stroke sensor 24 is attached to the master cylinder of the clutch 4 and outputs a detection signal corresponding to the amount of displacement of the piston of the master cylinder.

The wheel speed sensor 25 is provided for each wheel (drive wheel 6 and driven wheel) of the vehicle 1 and outputs a pulse signal synchronized with the rotation of each wheel as a detection signal. From the detection signal of the wheel speed sensor 25, the frequency of the detection signal (pulse signal) can be obtained, and the wheel speed can be obtained from the frequency. Furthermore, the vehicle speed of the vehicle 1 can be obtained from the wheel speed.

The forward detection sensor 26 is a sensor that detects obstacles present in front of the vehicle 1 . A stereo camera, ultrasonic sonar, LIDAR sensor, or radar can be used for the forward detection sensor 26 . If the forward detection sensor 26 is a stereo camera, the stereo camera is installed, for example, in front of the room mirror at the front center of the vehicle interior so as to be able to image the front of the vehicle 1 at a wide angle. In a stereo camera, target pixels corresponding to the same object in each image captured by the image sensor are extracted from a pair of image data input from image sensors for both the left and right eyes, and target pixels between the pair of images are extracted. is detected, and the distance to the same object is calculated by the principle of triangulation. The stereo camera outputs a detection signal corresponding to the calculated distance.

The steering angle sensor 27 outputs a detection signal corresponding to the steering angle (absolute steering angle) of the steering mechanism (for example, steering wheel) of the vehicle 1 with respect to the steering angle midpoint.

The slope sensor 28 is a sensor that detects the slope of the road surface on which the vehicle 1 travels. A G sensor, for example, can be used for the gradient sensor 28 . The G sensor outputs a signal corresponding to the displacement of the weight as a detection signal corresponding to the acceleration of the vehicle 1 . The acceleration of the vehicle 1 can be obtained from the detection signal of the G sensor. The acceleration obtained from the detection signal of the G sensor includes an acceleration component due to a change in vehicle speed and an acceleration component due to the gradient of the road surface on which the vehicle 1 is located. On the other hand, the acceleration obtained by differentiating the vehicle speed obtained from the detection signal of the wheel speed sensor 25 is only the acceleration component due to the change in the vehicle speed. Therefore, by obtaining the difference between the acceleration obtained from the detection signal of the G sensor and the differential value of the vehicle speed, the acceleration component due to the slope of the road surface on which the vehicle 1 is traveling can be obtained. can be estimated.

Part or all of the accelerator sensor 22, brake sensor 23, clutch stroke sensor 24, wheel speed sensor 25, forward detection sensor 26, steering angle sensor 27, and gradient sensor 28 may be connected to another ECU, In that case, the ECU 21 may acquire information obtained from those detection signals from another ECU through communication.

The ECU 21 is an engine ECU that controls the engine 2 by executing various processes based on programs stored in a nonvolatile memory based on detection signals input from each sensor and/or information input from other ECUs. , a brake ECU that controls the brake mechanism 14, and a meter ECU that controls a meter panel on which a display 31 and a buzzer 32 are arranged. The indicator 31 may be, for example, a multi-information display provided on the meter panel or an indicator provided on the meter panel.

The ECU 21 determines that the accelerator pedal 11 is mistakenly stepped on for the brake pedal 12, and when the accelerator pedal 11 is erroneously stepped on occurs, the ECU 21 reduces the damage of accidents (collisions) caused by the erroneous stepping or suppresses the occurrence of accidents. A pedal depression process is executed, and a command is output to the engine ECU and the meter ECU.

In addition, the ECU 21 determines the possibility of collision between the vehicle 1 and an obstacle in front of the vehicle 1, and if there is a possibility of collision between the vehicle 1 and an obstacle, the ECU 21 reduces the damage caused by the collision or avoids the collision. , to give a command to the brake ECU to perform automatic brake control in which braking force is automatically applied to each wheel from the brake mechanism 14 . Further, the ECU 21 gives a command to the meter ECU to perform display on the indicator 31 and to sound the buzzer 32 to inform the operation of the automatic brake when the automatic brake is applied.

In judging the possibility of collision, when an obstacle (target) exists in front of the vehicle 1, the distance between the vehicle 1 and the obstacle is obtained from the detection signal of the forward detection sensor 26, and the vehicle A relative velocity between 1 and the obstacle is obtained, and a predicted time to collision (TTC: Time To Collision) is calculated from the distance and the relative velocity. Then, the ECU 21 determines that there is a possibility of collision between the vehicle 1 and an obstacle when the collision prediction time reaches a predetermined time.

<Pedal misapplication processing>
FIG. 2 is a flow chart showing the flow of processing for determining the start, end, and content of pedal depression processing.

In the state in which the pedal depression process is not performed, the AP depression amount, which is the depression amount of the accelerator pedal 11, and the AP depression speed, which is the change speed of the AP depression amount, are obtained from the detection signal of the accelerator sensor 22 . The AP depression amount is obtained as a ratio (%) of the depression amount to the maximum depression amount of the accelerator pedal 11, and the AP depression speed is obtained by time differentiation of the AP depression amount. Then, it is determined whether or not the AP depression speed is greater than a predetermined reference speed Aos (%/s) (step S1). Further, it is determined whether or not the AP depression amount is greater than a predetermined start reference amount Ap1 (%) (step S2). The reference speed Aos and the start reference amount Ap1 are set, for example, with reference to the depression speed and depression amount when the accelerator pedal 11 is depressed with the depression force input to the brake pedal 12 during sudden braking.

The accelerator pedal 11 is often stepped on more slowly than the brake pedal 12 . Therefore, when the accelerator pedal 11 is quickly and strongly depressed, there is a possibility that the accelerator pedal 11 is mistakenly depressed for the brake pedal 12 . Therefore, when the AP depression amount is greater than the start reference amount Ap1 and the AP depression speed is greater than the reference speed Aos (YES in steps S1 and S2), an erroneous depression occurs in which the accelerator pedal 11 is mistakenly depressed for the brake pedal 12. Then, it is decided to start the pedal depression process (step S3). The erroneous pedal depression process includes engine output suppression control for suppressing the output of the engine 2 in order to suppress sudden acceleration (erroneous start) of the vehicle 1 due to the erroneous pedal depression. Further, in the pedal depression process, in order to inform the driver that the accelerator pedal 11 is mistakenly depressed for the brake pedal 12, a warning is displayed on the display 31 and an HMI (Human Machine Interface) that causes a buzzer 32 to sound. : Human Machine Interface) control is included. Along with the decision to start the pedal depression process, execution of engine output suppression control and HMI control is decided.

On the other hand, when the AP depression speed is equal to or lower than the reference speed Aos (NO in step S1), the pedal depression process is not started, the AP depression speed is obtained again, and the obtained AP depression speed is the reference speed Aos. It is again determined whether it is greater than (step S1). Further, even if the AP depression speed is greater than the reference speed Aos, if the AP depression amount is equal to or less than the start reference amount Ap1 (NO in step S2), the pedal depression process is not started, and the AP depression amount and the AP depression amount are not started. The speed is obtained again, and it is again determined whether or not the AP depression speed is greater than the reference speed Aos (step S1). Determination as to whether or not it is greater is made again (step S2).

After determining the start of the pedal depression process, the AP depression amount is obtained again, and it is determined whether or not the AP depression amount at that time is less than a predetermined end reference amount Ap2 (step S4). The end reference amount Ap2 may have the same value as the start reference amount Ap1, or may have a different value from the start reference amount Ap1. Also, the end reference amount Ap2 may be a fixed value, or may be variably set according to whether the engine output suppression control is being performed.

When the AP depression amount is equal to or greater than the end reference amount Ap2 (NO in step S4), the CP depression amount, which is the depression amount of the clutch pedal 13, is obtained from the detection signal of the clutch stroke sensor 24. The CP depression amount is obtained as a ratio (%) of the depression amount to the maximum depression amount of the clutch pedal 13 . Then, it is determined whether or not the CP depression amount is greater than a predetermined reference amount Cp (%) (step S5). The reference amount Cp is set to a value close to 0, for example, a value of 10 or less with reference to the depression amount of the clutch pedal 13 when the clutch 4 is released.

If the CP depression amount is equal to or less than the reference amount Cp (NO in step S5), continuation of the pedal depression process is determined, and engine output suppression control and HMI control are continued (step S6). In the engine output suppression control, in order to suppress the output of the engine 2, for example, an electronic throttle valve is controlled to reduce the rotation speed of the engine 2 to a predetermined rotation speed. The predetermined number of revolutions is determined based on the vehicle speed of the vehicle 1 and the gear ratio (gear stage) of the manual transmission 3, for example, and is the lowest number of revolutions at which the engine 2 does not stall when the clutch 4 is engaged. and is set to a rotational speed that is higher than that rotational speed by a predetermined amount. Thereafter, the AP depression amount is obtained again, and it is determined whether or not the AP depression amount at that time is less than a predetermined end reference amount Ap2 (step S4).

If the clutch pedal 13 is depressed while the accelerator pedal 11 is depressed to the end reference amount Ap2 or more and the CP depression amount is greater than the reference amount Cp (YES in step S5), the pedal misapplication processing is continued. , the engine output suppression control is ended, and only the HMI control is continued (step S7). Since the engine output suppression control is terminated when the accelerator pedal 11 is depressed by the termination reference amount Ap2 or more, the rotation speed of the engine 2 rapidly increases from the predetermined rotation speed to the rotation speed corresponding to the AP depression amount. At this time, since the clutch 4 is released by depressing the clutch pedal 13 more than the reference amount Cp, even if the rotation speed of the engine 2 increases, the driving force transmitted to the drive wheels 6 does not increase. Without this, the engine 2 is in a state of racing. Thereafter, the AP depression amount is obtained again, and it is determined whether or not the AP depression amount at that time is less than a predetermined end reference amount Ap2 (step S4).

When the depression of the accelerator pedal 11 is released and the AP depression amount falls below the end reference amount Ap2 (YES in step S4), it is determined that the pedal depression process is terminated, and engine output suppression control and HMI control are executed. Both are terminated (step S8).

<Effect>
As described above, the stepping operation of the accelerator pedal 11 is performed, and the degree of the stepping operation is equal to or greater than a predetermined amount, specifically, the AP depression amount, which is the depression amount of the accelerator pedal 11, is larger than the start reference amount Ap1, and , and when the AP depression speed, which is the change speed of the AP depression amount, is greater than the reference speed Aos, pedal depression processing is performed. In the erroneous pedal depression process, it is determined whether or not to perform engine output suppression control for suppressing the output of the engine 2 based on the CP depression amount, which is the degree of release operation of the clutch pedal 13 .

For example, while the vehicle 1 is running (running idle or running under cruise control) with none of the accelerator pedal 11, brake pedal 12, and clutch pedal 13 being operated, the red light of the traffic signal in the direction of travel is turned on. As a result, the vehicle 1 needs to be decelerated, and if the driver depresses the accelerator pedal 11 by mistakenly depressing the brake pedal 12, the vehicle 1 is rapidly accelerated because the clutch 4 is engaged. , there is a possibility that an accident may occur due to the sudden acceleration.

Therefore, when the AP depression amount is greater than the start reference amount Ap1 and the AP depression speed is greater than the reference speed Aos, the CP depression amount is equal to or less than the reference amount Cp, and the engaged state of the clutch 4 is maintained. If so, it is determined to implement the engine output suppression control, and the engine output suppression control is implemented. As a result, the output of the engine 2 is suppressed and the running of the vehicle 1 is suppressed, so if the foot operation of the accelerator pedal 11 is mistakenly performed for the foot operation of the brake pedal 12, an accident due to the operation mistake. It is possible to reduce the damage or suppress the occurrence of accidents.

On the other hand, even if the AP depression amount is greater than the start reference amount Ap1 and the AP depression speed is greater than the reference speed Aos, when the CP depression amount is greater than the reference amount Cp and the clutch 4 is released, the engine A decision is made not to implement the output suppression control (decision to end). Disengagement of the clutch 4 disconnects the engine 2 from the manual transmission 3, and the vehicle 1 accelerates even if the rotation speed of the engine 2 increases (the output of the engine 2 increases) in response to the stepping operation of the accelerator pedal 11. Therefore, it is possible to reduce the damage caused by an accident caused by an operation error or to suppress the occurrence of an accident.

Moreover, since the vehicle 1 does not accelerate even though the number of revolutions of the engine 2 has increased, it is easy for the driver to notice that the stepping operation of the brake pedal 12 is mistaken for the stepping operation of the accelerator pedal 11 . Therefore, it can be expected that the stepping operation of the accelerator pedal 11 will be stopped and the stepping operation of the brake pedal 12 will be performed sooner after the occurrence of the operation error. As a result, it is possible to further reduce the damage caused by accidents caused by erroneous operations or to further suppress the occurrence of accidents.

Further, in the pedal depression process, HMI control is performed to display a warning on a display 31 and to sound a buzzer 32 in order to inform the driver that the accelerator pedal 11 is depressed by mistake for the brake pedal 12.例文帳に追加This notification enables the driver to quickly notice that the driver has mistaken the braking operation of the brake pedal 12 for the acceleration operation of the accelerator pedal 11 . As a result, it can be expected that the stepping operation of the accelerator pedal 11 will be stopped and the stepping operation of the brake pedal 12 will be performed sooner after the occurrence of the operation error, thereby further reducing or reducing the damage caused by the accident caused by the operation error. can be further suppressed.

<Modification>
Although one embodiment of the present invention has been described above, the present invention can also be implemented in other forms.

For example, in the above-described embodiment, after the start of the pedal misapplication process is determined, the AP depression amount is obtained again, and when the AP depression amount is less than the end reference amount Ap2, the end of the pedal misapplication process is decided. However, when the AP depression speed is obtained, in addition to or instead of determining whether the AP depression amount is less than the end reference amount Ap2, the AP depression speed is determined to be less than a negative predetermined value. (whether or not the speed of change in the direction of decreasing the amount of AP depression (the direction in which the accelerator pedal 11 is released) is greater than a predetermined value), and the determination is affirmative. In this case, it may be determined to end the pedal depression process.

Further, the AP depression acceleration, which is the time differential value of the AP depression speed, is obtained, and in addition to or instead of determining whether or not the AP depression amount is less than the end reference amount Ap2, the AP depression acceleration is less than a predetermined negative value (whether the acceleration of the change in the decreasing direction of the AP depression amount (the direction in which the accelerator pedal 11 is released) is greater than a predetermined value). , when the determination is affirmative, it may be determined to end the pedal depression process.

Although the accelerator pedal 11, the brake pedal 12 and the clutch pedal 13 are taken up as the accelerator operating member, the brake operating member and the clutch operating member, respectively, the accelerator operating member, the brake operating member and the clutch operating member are limited to pedals operated by foot.

In the above-described embodiment, "when the degree of acceleration operation of the accelerator operation member is greater than the accelerator reference" is defined as the case where the AP depression amount is greater than the start reference amount Ap1 and the AP depression speed is greater than the reference speed Aos. However, the AP depression amount may be greater than the start reference amount Ap1 or the AP depression speed may be greater than the reference speed Aos.

In the above-described embodiment, the running of the vehicle 1 is suppressed by suppressing the output of the engine 2, which is the drive source. Travel may be suppressed.

Further, although the pedal depression process includes engine output suppression control and HMI control, HMI control may be omitted, and automatic brake control may be included.

The clutch stroke sensor 24 is not limited to a configuration that outputs a detection signal according to the displacement amount of the piston of the master cylinder of the clutch 4, and may be configured to output a detection signal according to the displacement amount of the release fork.
