JP 2010-142300 A

  However, since the above technique only indicates the travel position of the vehicle on the travel course, the method by which the vehicle is actually bent on the curve of the travel course, that is, the vehicle slips the tire. Therefore, there is a problem that it is impossible to determine whether the vehicle is bent due to grip traveling or whether the vehicle is bent due to drift traveling by slipping a tire, and thus the traveling behavior of the vehicle cannot be appropriately reproduced.

  The problem to be solved by the present invention is to appropriately reproduce the traveling behavior when the vehicle changes the traveling direction when reproducing the traveling behavior of the vehicle based on the information acquired from the vehicle actually traveling on the traveling path. It is to provide a travel information collection processing device and a travel information collection processing method that can be performed.

  In the present invention, when a four-wheeled vehicle travels in a traveling direction change section such as a curve, a rotational speed ratio, which is a ratio between the rotational speed of the left and / or right front wheels of the vehicle and the rotational speed of the rear wheels, is within a predetermined range. And when it is determined that the driver has steered in the direction opposite to the direction of the curve, the traveling direction is changed while slipping of all four tires of the vehicle in the traveling direction changing section. It is determined that wheel drift has occurred, and travel history data that reproduces the actual travel of the vehicle is generated, thereby solving the above-described problem.

  According to the present invention, since the presence or absence of the four-wheel drift is determined based on the above-described rotation speed ratio and the steering by the driver, the traveling behavior of the vehicle can be appropriately reproduced.

The control device 31 of the computer 30 includes a ROM (Read Only Memory) 312 in which a program for reproducing traveling of the vehicle 10 based on log information of the vehicle 10 is stored, and an operation control circuit for executing the program stored in the ROM 312. A CPU (Central Processing Unit) 311 and a RAM (Random Access Memory) 313 functioning as an accessible storage device.

  The control device 31 of the computer 30 of the present embodiment includes an acquisition function that acquires log information of the vehicle 10 from the storage medium 20, a detection function that detects a rotation speed ratio between the front wheels and the rear wheels in the vehicle 10, and the vehicle 10 A determination function for determining whether or not drift traveling has been performed, a traveling history data generation function for generating data for reproducing the traveling of the vehicle 10, and reproduction for reproducing the traveling of the vehicle 10 and reproducing it with video and traveling sound With functions. The control device 31 of the present embodiment executes each function by cooperation of software for realizing the above function and the above-described hardware.

Hereinafter, each function of the control device 31 according to the present embodiment will be described.
First, the acquisition function of the control device 31 will be described. When the storage medium 20 described above is connected to the communication device 32 of the computer 30, the control device 31 copies the log information of the vehicle 10 stored in the storage medium 20 to the storage device 33 of the computer 30. To remember.

Next, the detection function of the control device 31 will be described. The control device 31 extracts the rotational speed of each wheel (left front wheel, left rear wheel, right front wheel, and right rear wheel) of the vehicle 10 from the log information of the vehicle 10 stored in the storage device 33. Then, the control device 31 determines a left wheel rotation speed ratio (RT _LR / RT _LF ) that is a ratio of the rotation speed RT _LR of the left rear wheel to the rotation speed RT _LF of the left front wheel based on the rotation speed of each wheel of the vehicle 10. The right wheel rotation speed ratio (RT _RR / RT _RF ), which is the ratio of the right rear wheel rotation speed RT _{RR to} the right front wheel rotation speed RT _RF , is detected.

Next, the determination function of the control device 31 will be described. Based on the left wheel rotation speed ratio (RT _LR / RT _LF ) and right wheel rotation speed ratio (RT _RR / RT _RF ) detected by the detection function, the control device 31 travels in a travel direction change section such as a curve. It is determined whether or not the vehicle has drifted.

Here, in the present embodiment, the control device 31 uses only the position information of the vehicle 10 included in the log information described above, and the vehicle 10 slips the tire when the vehicle 10 changes the travel direction in the travel direction change section. It is not possible to determine whether the vehicle has gripped without making it, or whether the vehicle 10 has drifted with the tire slipped. Therefore, the control device 31 detects the idling of the tire of the vehicle 10 based on the left wheel rotation speed ratio (RT _LR / RT _LF ) and the right wheel rotation speed ratio (RT _RR / RT _RF ) described above, and the vehicle 10 It is determined whether or not the vehicle has drifted.

  In the present embodiment, the drift traveling refers to changing the direction of the vehicle body while the tire of any wheel of the vehicle 10 slips with respect to the road surface. As a type of drift driving, for example, by entering a curve at high speed and appropriately performing a brake operation or a steering operation, the tires of the rear wheels (left rear wheel and right rear wheel) are mainly slipped. Traveling to change the direction of the vehicle body (hereinafter referred to as rear wheel drift traveling) by using the centrifugal force of the vehicle body with the front wheel being substantially the rotation center while reducing the slip amount of the tires of the front wheels (left front wheel and right front wheel) .).

Here, FIG. 2A is a top view continuously showing the vehicle 10 that has traveled rear-wheel drifting along the curve of the travel path. 2A shows four tires (a left front tire LF, a left rear tire LR, a right front tire RF, and a right rear tire RR) provided in the vehicle 10, and the left front tire LF and the right front tire in the vehicle length direction of the vehicle 10 are shown. The angle of RF indicates the steering angle based on the driver's steering operation. Moreover, in FIG. 2A, the tires that are recognized as slipping with respect to the road surface are marked with x. Here, as a tire recognized as slipping with respect to the road surface, for example, an actual tire with respect to the vehicle speed v ₁ in the tire rotation direction obtained from the rotation speed of the tire when the tire is gripping the road surface There are tires in which the ratio (v ₂ / v ₁ ) of the vehicle speed v _{2 in} the rotational direction is equal to or less than a predetermined value. Moreover, in FIG. 2A, the route along which the vehicle 10 has traveled is indicated by a broken line.

  In the present embodiment, when the vehicle 10 performs the rear wheel drift traveling as shown in FIG. 2A, traveling information at the time of the rear wheel drift traveling is acquired as log information by the vehicle 10 and is stored via the storage medium 20. And stored in the computer 30. Then, the computer 30 reproduces the traveling of the vehicle 10 with a video and a traveling sound based on the log information by a reproduction function described later. For that purpose, the behavior of the vehicle 10 is reproduced more accurately based on the log information. Is required.

Here, as described above, the control device 31 determines whether the vehicle 10 has gripped or drifted in a scene where the vehicle 10 has changed the traveling direction, depending only on the position information of the vehicle 10 included in the log information. Cannot be judged. Therefore, the control device 31 detects the idling of the tire of the vehicle 10 based on the left wheel rotation speed ratio (RT _LR / RT _LF ) and the right wheel rotation speed ratio (RT _RR / RT _RF ) described above, and the vehicle 10 It is determined whether or not the vehicle has drifted.

Specifically, the control device 31 determines that at least one of the left wheel rotation speed ratio (RT _LR / RT _LF ) and the right wheel rotation speed ratio (RT _RR / RT _RF ) is a predetermined upper limit threshold (any one greater than 1). Value) or more, it is determined that the rear wheel (left rear wheel and / or right rear wheel) is idling and slipping. In this case, it is determined that the vehicle 10 has traveled the rear wheel drifting. To do.

In addition, although the example which determines the rear-wheel drift driving | running | working of the vehicle 10 was shown in the example mentioned above, the control apparatus 31 of this embodiment can also determine whether the vehicle 10 carried out front-wheel drift driving | running | working. Here, the front wheel drift traveling is performed, for example, by causing the vehicle 10 to move backward at a high speed and appropriately performing a brake operation or a steering operation to slip only the front wheels and relatively reduce the slip amount of the rear wheels. This is traveling in which the direction of the vehicle body is changed by utilizing the centrifugal force of the vehicle body with the rear wheel as a substantially rotational center. In the present embodiment, the control device 31 is configured such that at least one of the left wheel rotation speed ratio (RT _LR / RT _LF ) and the right wheel rotation speed ratio (RT _RR / RT _RF ) has a predetermined lower threshold value (arbitrary value smaller than 1). (Value) or more, it is determined that the front wheel (the left front wheel and / or the right front wheel) is idling and slipping. In this case, it is determined that the vehicle 10 has traveled the front wheel drift.

  Note that the rear wheel drift traveling and the front wheel drift traveling are not limited to the shape of the travel path on which the vehicle 10 travels, but are not only drift travel that changes the direction of the vehicle body on the curve of the travel path, but also the direction of the vehicle body on the straight road. Also includes drift travel that changes 180 °.

  The control device 31 of the present embodiment determines the rear wheel drift traveling and the front wheel drift traveling of the vehicle 10 as described above.

  On the other hand, as a type of drift traveling in the present embodiment, traveling (hereinafter referred to as four-wheel drift traveling) in which the tires of all the wheels of the vehicle 10 are slipped to the same extent and the direction of the vehicle body is changed is also exemplified. Here, FIG. 2B is a top view continuously showing the vehicle 10 that has traveled four-wheel drift along the curve of the travel path. In FIG. 2B, as in the case of FIG. 2A described above, tires that are recognized as slipping with respect to the road surface are marked with a cross. Moreover, in FIG. 2B, the route along which the vehicle 10 has traveled is indicated by a broken line.

Here, when the vehicle 10 performs the four-wheel drift traveling, the tires of all the wheels of the vehicle 10 usually idle to the same extent, so the left wheel rotational speed ratio (RT _LR / RT _LF ) or the right Since the wheel rotation speed ratio (RT _RR / RT _RF ) is a value near 1, which is the same value as the scene in which the vehicle 10 gripped, the left wheel rotation speed ratio (RT _LR / RT _LF ) and the right wheel rotation speed There is a problem that the four-wheel drift traveling cannot be detected appropriately only by the ratio (RT _RR / RT _RF ).

In contrast, in the present embodiment, when the vehicle 10 travels in a travel direction change section such as a curve, the left wheel rotation speed ratio (RT _LR / RT _LF ) and the right wheel rotation speed ratio (RT _RR / RT _RF ) When it is determined that at least one of them is in the range of 1 ± 0.05 and the steering in the direction opposite to the curve direction (so-called reverse steering) is performed by the driver, the control device 31 In the direction change section, it is determined that the vehicle 10 has traveled by four-wheel drift.

  That is, as shown in FIG. 2B, when four-wheel drift traveling is performed on a curve, steering in a direction opposite to the direction of the curve is performed by the driver. Here, in FIG. 2B showing a scene in which the four-wheel drift running is performed, the tire steered in the direction opposite to the curve direction is shown in gray. In FIG. 2B, the position of the vehicle 10 at times t1 to t4 is indicated by 10 (t1) to 10 (t4), respectively.

  As shown in FIG. 2B, when the vehicle 10 starts the four-wheel drift traveling, normally, as shown by the left front tire LF and the right front tire RF at the position 10 (t1), once entering the curve, Steering is often performed in a direction opposite to the direction. This is because, after steering in the direction opposite to the direction of the curve at the position 10 (t1), immediately after steering in the direction of the curve at the position 10 (t2), the suspension force of the vehicle 10 returns and the steering Is added to the centrifugal force, and the direction of the vehicle 10 changes at a stretch as shown at position 10 (t3). Since the vehicle 10 is traveling at a sufficient vehicle speed at the position 10 (t1), a sufficient traveling inertial force is exerted on the vehicle 10 in the traveling direction.

Therefore, in the present embodiment, at least one of the left wheel rotation speed ratio (RT _LR / RT _LF ) and the right wheel rotation speed ratio (RT _RR / RT _RF ) is 1 ± 0.05 in the travel direction change section such as a curve. When the rotational speed of the front wheel and the rear wheel of the vehicle 10 is approximately the same, when steering in the direction opposite to the curve direction is detected, the travel direction change section is entered. Thus, it is determined that the vehicle 10 has traveled by four-wheel drift. Thereby, according to the present embodiment, whether or not the four-wheel drift traveling of the vehicle 10 is appropriately detected is detected, and the traveling of the vehicle 10 is reproduced based on the log information acquired from the vehicle 10 that actually traveled on the road surface. The behavior of the vehicle 10 can be appropriately reproduced. According to the verification by the present inventors, at least one of the left wheel rotation speed ratio (RT _LR / RT _LF ) and the right wheel rotation speed ratio (RT _RR / RT _RF ) is in the range of 1 ± 0.05. For example, it can be determined that four-wheel draft traveling is being performed. Conversely, if the rotational speed ratio is not in the range of 1 ± 0.05, it can be determined that the rear wheel draft, the front wheel draft, or the simple idling of the tire at the start.

  As shown in FIG. 2B, when the four-wheel drift traveling of the vehicle 10 is performed, the steering in the reverse direction may be performed a plurality of times during the four-wheel drift traveling. In the example shown in FIG. 2B, the vehicle 10 is first steered in the reverse direction at the position 10 (t1) at which the four-wheel drift traveling starts, and further while the four-wheel drift traveling is performed. In order to control the posture, the steering in the reverse direction is appropriately performed at the time of the position 10 (t3) or the position 10 (t4).

  Therefore, in the present embodiment, in a travel direction change section such as a curve, when a steering in a direction opposite to the direction of the curve, that is, a reverse handle is detected at least once within a predetermined time, the direction of the curve is defined as It may be determined that steering in the reverse direction is performed by the driver. As a result, even when reverse direction steering is detected a plurality of times in the travel direction change section, it is determined that this is one reverse direction steering. Although it is only performed once, it is possible to prevent erroneous determination that the four-wheel drift traveling has been performed a plurality of times. The predetermined time is not particularly limited, and can be set based on a normal time during which one four-wheel drift traveling is performed.

  Next, the travel history data generation function of the control device 31 will be described. The control device 31 is a travel history for reproducing the travel of the vehicle 10 based on the log information of the vehicle 10 acquired by the acquisition function described above and the information on the presence / absence of the drift travel determined by the determination function described above. Generate data.

  In the present embodiment, the travel history data includes, for example, the position of the vehicle 10, the steering amount, the steering speed, the steering acceleration, the vehicle speed, the acceleration, the wheel speed and the engine speed information, and the accelerator operation, brake operation, and shift by the driver. Information on operation and steering operation is included.

  The travel history data includes information on the type of the vehicle 10 (for example, information on the vehicle body shape, the vehicle body weight, the position of the center of gravity of the vehicle, the length of the wheelbase, the tire width, the coefficient of static friction of the tire, etc.) Information on the travel route (for example, information on the course layout of the circuit on which the vehicle 10 traveled, the background around the course, etc.) is also included. The information on the vehicle type of the vehicle 10 and the information on the travel route on which the vehicle 10 traveled are stored in advance in the storage device 33 of the computer 30, and the control device 31 refers to the log information of the vehicle 10 and stores the information. You may make it read from the apparatus 33 suitably.

  Next, the playback function of the control device 31 will be described. The control device 31 reproduces the travel of the vehicle 10 based on the travel history data generated by the travel history data generation function, and outputs it by the output device 34.

  For example, a case where travel history data is generated based on log information when the vehicle 10 travels on a circuit will be described as an example. First, the control device 31 uses the travel history data to determine information on a circuit on which the vehicle 10 has traveled. And 3D data reproducing the course layout and background of the corresponding circuit is read out from the storage device 33 or the like. Next, the control device 31 reads out information on the vehicle type of the vehicle 10 from the travel history data, and reads out 3D data reproducing the vehicle corresponding to the information from the storage device 33 or the like.

  Further, the control device 31 reads the log information of the vehicle 10 from the travel history data, and based on the log information, the position, steering amount, steering speed, steering acceleration, Parameters such as vehicle speed, acceleration, wheel speed, engine rotation speed, accelerator operation, brake operation, shift operation, and steering operation are input to generate an image in which a 3D data vehicle travels on a 3D data circuit. In particular, in the present embodiment, the drift travel of the vehicle 10 is reproduced based on the determination results of the presence or absence of four-wheel drift travel, rear wheel drift travel, and front wheel drift travel by the determination function of the control device 31.

  At the same time, the control device 31 synchronizes with the above-described video based on the wheel speed of the vehicle 10, the engine rotation speed of the vehicle 10, the information on the road surface of the circuit on which the vehicle 10 traveled, and the like. Ten driving sounds (engine sound, sound when the tire travels on the road surface, and squealing noise when the tire and the road surface rub) are generated. In particular, in the present embodiment, the squeal noise generated by the drift travel at the timing when it is determined by the determination function of the control device 31 that the vehicle 10 has performed drift travel such as four-wheel drift travel, rear wheel drift travel, and front wheel drift travel. Is generated.

  The control device 31 displays the generated video on the display 341 of the output device 34 and reproduces the generated traveling sound from the speaker 342. As a result, according to the present embodiment, the behavior of the vehicle 10 actually traveling in a four-wheel drift manner is accurately reproduced with the reproduced video and traveling sound, so that the user can view the reproduced video and traveling sound. A feeling and satisfaction can be given. In particular, when the driver who has driven the vehicle 10 himself / herself appreciates the video and sound that reproduces the traveling of the vehicle 10, the driver feels that his / her driving has been faithfully reproduced and is more satisfied. Can be obtained.

  In the present embodiment, as described above, the travel history data in which the presence or absence of the four-wheel drift travel is appropriately determined is generated by the control device 31 of the computer 30 based on the log information of the vehicle 10, and the travel history data is used. The traveling of the vehicle 10 is faithfully reproduced.

  Next, referring to the flowchart of FIG. 3, an example of a method for collecting the log information of the vehicle 10 by the travel information collection processing system 1 of the present embodiment and reproducing the travel of the vehicle 10 based on the collected log information. Will be explained. FIG. 3 shows control of the vehicle 10, the storage medium 20, and the computer 30, respectively.

  In step S101, the vehicle controller 11 of the vehicle 10 obtains position information corresponding to the time of the vehicle 10 from the GPS signal receiver 13, and the steering amount, steering speed, steering acceleration, vehicle speed, acceleration, wheel speed of the vehicle 10 from the sensor 14. The information such as the engine rotation speed is acquired, and the acquired information is stored in the storage device 17 as log information.

  In step S102, when the vehicle controller 11 of the vehicle 10 detects that the storage medium 20 is connected to the communication device 12 of the vehicle 10, the log information stored in the storage device 17 in step S101 is stored in the storage medium. 20

  In step S103, the storage medium 20 stores the log information input from the vehicle 10 in step S102.

  In step S <b> 104, when the storage medium 20 detects that the storage medium 20 is connected to the communication device 32 of the computer 30, the log information stored in step S <b> 103 is input to the computer 30.

  In step S105, the control device 31 of the computer 30 stores the log information input from the storage medium 20 in step S104.

In step S106, when the vehicle 10 travels in a travel direction change section such as a curve, the control device 31 of the computer 30 causes the left wheel rotation speed ratio (RT _LR / RT _LF ) and the right wheel rotation speed ratio (RT _RR / RT). _RF ) It is determined whether at least one of them is in the range of 1 ± 0.05. In step S106, it is determined that at least one of the left wheel rotation speed ratio (RT _LR / RT _LF ) and the right wheel rotation speed ratio (RT _RR / RT _RF ) in the travel direction change section is in the range of 1 ± 0.05. If so, the process proceeds to step S107. On the other hand, in step S106, it is determined that at least one of the left wheel rotation speed ratio (RT _LR / RT _LF ) and the right wheel rotation speed ratio (RT _RR / RT _RF ) in the travel direction change section is not in the range of 1 ± 0.05. If so, the process proceeds to step S110.

  In step S107, the control device 31 of the computer 30 determines whether or not steering by the driver in the direction opposite to the curve direction in the travel direction change section is performed. If it is determined in step S107 that the driver has steered in the direction opposite to the curve direction in the travel direction change section, the process proceeds to step S108. On the other hand, if it is determined in step S107 that the driver has not steered in the direction opposite to the curve direction in the travel direction change section, the process proceeds to step S110.

  In step S108, the control device 31 of the computer 30 generates the above-described travel history data on the assumption that four-wheel drift travel has been performed in the travel direction change section.

  In step S109, the control device 31 of the computer 30 generates a traveling image of the vehicle 10 in which the squeal noise of drift traveling is added to the timing when it is determined in step S107 that four-wheel drift traveling has been performed, and the output device 34 Output.

On the other hand, in step S106, it is determined that at least one of the left wheel rotation speed ratio (RT _LR / RT _LF ) and the right wheel rotation speed ratio (RT _RR / RT _RF ) in the travel direction change section is not in the range of 1 ± 0.05. If it is determined, or if it is determined in step S107 that the driver has not steered in the direction opposite to the curve direction in the travel direction change section, the process proceeds to step S110. In step S110, contrary to step S108 described above, the control device 31 of the computer 30 assumes that the four-wheel drift travel has not been performed in the travel direction change section, that is, grips in the travel direction change section. The traveling history data described above is generated as a result of traveling.

  In step S <b> 111, the control device 31 of the computer 30 generates a traveling image of the vehicle 10 without adding a drifting squeal sound and outputs the traveling image from the output device 34.

  Since the travel information collection processing system 1 of the present embodiment is configured and operates as described above, the following effects can be obtained.

[1] According to the traveling information collection processing system 1 of the present embodiment, the left wheel rotational speed ratio (RT _LR / RT _LF ) and the right wheel rotational speed ratio (RT _RR / RT _RF ) in the traveling direction change section such as a curve. When it is determined that at least one of them is in the range of 1 ± 0.05 and the steering in the direction opposite to the curve direction is performed by the driver, the vehicle 10 It is determined that a four-wheel drift that changes the traveling direction while all four tires slip is generated, and traveling history data that reproduces the actual traveling of the vehicle 10 is generated. Accordingly, whether or not the four-wheel drift traveling of the vehicle 10 is appropriately detected is detected, and when the traveling of the vehicle 10 is reproduced based on the log information acquired from the vehicle 10 actually traveling on the road surface, the behavior of the vehicle 10 is changed. Can be reproduced appropriately.

[2] According to the travel information collection processing system 1 of the present embodiment, when steering in a direction opposite to the curve direction is detected at least once within a predetermined time in a travel direction change section such as a curve. Then, it is determined that the driver has steered in the direction opposite to the curve direction. As a result, even when reverse direction steering is detected a plurality of times in the travel direction change section, it is determined that this is one reverse direction steering. Although it is only performed once, it is possible to prevent erroneous determination that the four-wheel drift traveling has been performed a plurality of times.

[3] According to the travel information collection processing system 1 of the present embodiment, the generated travel history data is reproduced by video, and tires and road surfaces are detected in a scene where it is determined that drift travel has occurred in the reproduced video. A rubbing squealing sound is added in synchronization with the video. As a result, the behavior of the vehicle 10 actually traveling by drifting four wheels is accurately reproduced from the reproduced video and traveling sound, and satisfaction can be given to the user who views the reproduced video and traveling sound. In particular, when the driver who has driven the vehicle 10 appreciates the video and sound that reproduces the traveling of the vehicle 10, the driver feels that his driving is faithfully reproduced, and more realistic and Satisfaction can be obtained.

[4] When the traveling information collection processing method of the present embodiment is executed by the computer 30, the same operation as that of the traveling information collection processing system 1 is achieved and the same effect is achieved.
