Summary of the Invention

Problems to be Solved by the Invention

[0004] In a vehicle display system, from the viewpoint of safety, in order to display on the display screen that a pedestrian walking in front of the vehicle or another vehicle in front of the vehicle has been detected as an obstacle and make the driver recognize it, it has been proposed to prohibit the driver from operating the display screen. However, in the above vehicle display system, when the driver desires to operate the display screen to check the vehicle state etc. during a temporary stop of the host vehicle due to a signal or a temporary stop of the host vehicle due to a traffic jam, if there is an object such as a pedestrian in front of the host vehicle, the display screen cannot be operated.

[0005] Therefore, the present invention has been made in view of these points, and an object thereof is to permit operation of the display screen at an appropriate timing.

Means for Solving the Problems

[0006] A display control device according to a first aspect of the present invention includes: a reception unit that receives operation of a display unit provided by a vehicle; a detection unit that detects an object in front of the vehicle; an acquisition unit that acquires vehicle speed information indicating the vehicle speed, pedal information indicating the state of the brake pedal operated by the driver of the vehicle, and transmission information indicating the state of the transmission operated by the driver; and a display control unit that causes the detection unit to detect the object and to display a first image on the display unit, wherein the display control unit changes the first image displayed on the display unit to a second image corresponding to the predetermined operation when the transmission is in neutral, the vehicle speed is below a predetermined vehicle speed, and the brake pedal is pressed, in response to the reception unit receiving a predetermined operation.

[0007] If the transmission is in a gear for forward movement, the display control unit may continue displaying the first image even if the reception unit receives a predetermined operation while the display unit is displaying the first image.

[0008] If the transmission is in reverse or parking position, the display control unit may change the first image displayed on the display unit to the second image in response to the reception unit receiving a predetermined operation while the first image is being displayed on the display unit.

[0009] If the vehicle speed is greater than a predetermined vehicle speed, the display control unit may continue displaying the first image even if the reception unit receives a predetermined operation while the display unit is displaying the first image.

[0010] If the brake pedal is not pressed, the display control unit may continue displaying the first image even if the reception unit receives the predetermined operation while the display unit is displaying the first image.

[0011] The display control unit further has a storage unit that stores a display table indicating permission or prohibition to change from the display of the first image to the display of the second image, corresponding to the vehicle speed, the state of the brake pedal, and the state of the transmission. If the state of the transmission included in the transmission information indicates neutral, the display control unit may refer to the display table and decide whether to change the first image displayed by the display unit to the second image or continue displaying the first image, based on the vehicle speed, the state of the brake pedal, and the state of the transmission acquired by the acquisition unit.

[0012] The display control unit may hide the first image even if the reception unit has not received the predetermined operation, when the transmission is in neutral, the vehicle speed is below a predetermined vehicle speed, and the brake pedal is pressed.

[0013] The system may further include a notification unit that informs the driver of the vehicle that, when the transmission is in neutral, the vehicle speed is below a predetermined speed, and the brake pedal is pressed, the first image can be changed to the second image, or the first image can be hidden.

[0014] The display control unit may cause the display unit to display the first image indicating that an object has been detected in front of the vehicle.

[0015] The display control unit may cause the display unit to display the second image, which indicates at least one of the vehicle's driving status and the status of the auxiliary equipment provided by the vehicle.

[0016] A second aspect of the present invention relates to a display control method comprising: a reception step performed by a computer to receive an operation of a display unit provided by a vehicle; a detection step to detect an object in front of the vehicle; an acquisition step to acquire vehicle speed information indicating the vehicle speed, pedal information indicating the state of the brake pedal operated by the driver of the vehicle, and transmission information indicating the state of the transmission operated by the driver; and a display control step to display a first image on the display unit as a result of detecting the object in the detection step, wherein in the display control step, if the state of the transmission is neutral, the vehicle speed is below a predetermined vehicle speed, and the brake pedal is depressed, the first image displayed on the display unit is changed to a second image corresponding to the predetermined operation in accordance with the reception step that a predetermined operation has been received. [Effects of the Invention]

[0017] According to the present invention, the effect is to allow operation of the display screen at the appropriate timing. [Brief explanation of the drawing]

[0018] [Figure 1] This diagram shows an overview of the vehicle S according to this embodiment. [Figure 2] This figure shows examples of the first and second images. [Figure 3] This figure shows an example of a display table. [Figure 4] This figure shows an example of a processing sequence in the display control device 10. [Modes for carrying out the invention]

[0019] <Overview of Vehicle S> FIG. 1 is a diagram showing an overview of a vehicle S according to the present embodiment. The vehicle S shown in FIG. 1 includes an operation unit 1, an object detection sensor 2, a vehicle speed sensor 3, a depression amount sensor 4, a position sensor 5, a display unit 6, a sound output unit 7, and a display control device 10. The vehicle S has a function of displaying, on a display included in an instrument panel, a first image indicating that an object in front of the vehicle S has been detected and a second image indicating a vehicle state such as a traveling state of the vehicle S and a state of auxiliary equipment. The object is, for example, a pedestrian, a bicycle, or another vehicle in front of the vehicle S. The traveling state is, for example, a traveling distance, an average fuel consumption, and an average vehicle speed, and the state of the auxiliary equipment is, as an example, the necessity of DPD (Diesel Particulate Diffuser) regeneration.

[0020] The operation unit 1 is a switch or a touch panel provided on the instrument panel or the steering wheel for the driver to operate. The driver of the vehicle S can display the first image or the second image on the display included in the instrument panel by operating a switch provided on the instrument panel, for example.

[0021] The object detection sensor 2 is a sensor for detecting an object in front of the vehicle S and includes, for example, an infrared sensor. The object detection sensor 2 detects an object included in a range within 4 m from the tip of the vehicle S in the traveling direction of the vehicle S and within 2 m from the center of the vehicle S in the vehicle width direction of the vehicle S, and outputs a detection signal indicating that the object has been detected. The vehicle speed sensor 3 includes a sensor for detecting the vehicle speed of the vehicle S and outputs vehicle speed information indicating the detected vehicle speed. The depression amount sensor 4 includes a sensor for detecting that the brake pedal of the vehicle S has been depressed and outputs pedal information indicating whether or not the brake pedal has been depressed.

[0022] The position sensor 5 includes a sensor for detecting the state of gears included in a transmission (not shown) corresponding to the shift position of the shift lever operated by the driver. The state of the gears is, for example, the number of engaged forward gears, whether the reverse gear is engaged, and whether the gear is fixed. The position sensor 5 includes, for example, a gear position sensor for detecting the number of engaged forward gears and a reverse gear sensor for detecting that the reverse gear is engaged, and outputs transmission information including the state of the transmission corresponding to the detected state of the gears. The state of the transmission is, for example, drive "D" or the number of engaged forward gears, parking "P", reverse "R", neutral "N".

[0023] For example, when the position sensor 5 detects that the gear is in a fixed state, it determines that the state of the transmission is parking "P". For example, when the position sensor 5 detects that the reverse gear is engaged, it determines that the state of the transmission is reverse "R". For example, when the position sensor 5 detects that the forward gear is not engaged, the reverse gear is not engaged, and the gear is not fixed, it determines that the state of the transmission is neutral "N". When the state of the transmission is neutral "N", the vehicle S does not move even if the driver steps on the accelerator. When the position sensor 5 detects that the number of engaged forward gears is 1 or more, it determines that the state of the transmission is drive "D". The position sensor 5 may include a shift position sensor and output transmission information including the state of the transmission corresponding to the position of the shift lever detected by the shift position sensor.

[0024] The display unit 6 is a display included in the instrument panel of the vehicle S and displays a switchable first image and second image. For example, when the display control device 10 controls the display unit 6 to display one of the first image and the second image, the other image is made non-displayed. The sound output unit 7 is a speaker provided around the instrument panel of the vehicle S.

[0025] The display control device 10 is a device for displaying the first image and the second image on the display unit 6. Figure 2 is a diagram showing an example of the first image and the second image. Figure 2 shows the first image G1 and a plurality of second images G2 (second image G2a, second image G2b, and second image G2c). The first image G1 includes an image showing the vehicle S, an image showing an object J in front of the vehicle S, and a warning image W indicating that object J has been detected. The second image G2a is an image of a selection screen in which the driver selects the type of vehicle status to be displayed on the display unit 6, the second image G2b is an image showing the driving status of the vehicle S, and the second image G2c is an image showing the status of the auxiliary equipment of the vehicle S. The second images G2b and G2c are images that are displayed when the driver makes a selection while the selection screen (second image G2a) is displayed on the display unit 6.

[0026] The display control device 10 displays the first image G1 on the display unit 6 when, for example, the object detection sensor 2 detects an object J. The display control device 10 also changes the first image G1 displayed on the display unit 6 to the second image G2a, or changes the second image G2a displayed on the display unit 6 to the second image G2b or the second image G2c, in response to, for example, the driver operating the operation unit 1.

[0027] Incidentally, from a safety standpoint, the display control device 10 is required to prioritize displaying the first image G1 over the second image G2 on the display unit 6. In response to this, the display control device 10 can prioritize displaying the first image G1 on the display unit 6 by displaying the first image G1 even if the driver attempts to display the second image G2 on the display unit 6 when the object detection sensor 2 detects an object J. However, in this case, even in the event of traffic congestion or a temporary stop due to a traffic light, the display control device 10 will display the first image G1 without displaying the second image G2 because the object detection sensor 2 has detected another vehicle in front of the vehicle or a pedestrian crossing the sidewalk. As a result, the driver has fewer opportunities to check the status of the vehicle S, making it difficult for the driver to check the vehicle status.

[0028] Therefore, when the position sensor 5 detects that the transmission is in neutral ("N"), the display control device 10 changes the first image G1 displayed on the display unit 6 to the second image G2 corresponding to the operation received by the operation unit 1, provided that the vehicle S is stopped. By operating in this manner, even if the object detection sensor 2 detects an object J in front of the vehicle S when the vehicle S is temporarily stopped, the display control device 10 can display the second image G2 corresponding to the driver's operation by having the driver keep the shift lever in the neutral ("N") position. The configuration and operation of the display control device 10 will be described in detail below.

[0029] <Configuration of the display control device 10> As shown in Figure 1, the display control device 10 has a storage unit 11 and a control unit 12. The control unit 12 has a receiving unit 121, a detection unit 122, an acquisition unit 123, a display control unit 124, and a notification unit 125.

[0030] The storage unit 11 has a storage medium such as ROM (Read Only Memory), RAM (Random Access Memory), HDD (Hard Disk Drive), or SSD (Solid State Drive). The storage unit 11 stores the program executed by the control unit 12 and various information for displaying the first image G1 and the second image G2 on the display unit 6.

[0031] The control unit 12 is a processor such as a CPU (Central Processing Unit) or an ECU (Electronic Control Unit). By executing a program stored in the storage unit 11, the control unit 12 functions as a reception unit 121, a detection unit 122, an acquisition unit 123, a display control unit 124, and a notification unit 125. The control unit 12 may consist of a single processor, or it may consist of multiple processors or a combination of one or more processors and electronic circuits.

[0032] The reception unit 121 receives operations from the display unit 6 provided by the vehicle S. The reception unit 121 receives operations such as switching the display between the first image G1 and the second image G2a, or switching the currently displayed second image G2 (second image G2a, second image G2b, and second image G2c) to another second image G2. The detection unit 122 detects an object J in front of the vehicle S. The detection unit 122 detects the object J, for example, by acquiring a detection signal indicating that the object detection sensor 2 has detected the object J.

[0033] The acquisition unit 123 acquires vehicle speed information indicating the vehicle speed of vehicle S. The acquisition unit 123 acquires vehicle speed information including, for example, the vehicle speed detected by the vehicle speed sensor 3. The acquisition unit 123 acquires pedal information indicating the state of the brake pedal operated by the driver of vehicle S. The acquisition unit 123 acquires pedal information indicating, for example, whether or not the brake pedal of vehicle S is depressed, as detected by the depression amount sensor 4. The acquisition unit 123 acquires transmission information indicating the state of the transmission operated by the driver. The acquisition unit 123 acquires transmission information including, for example, the state of the transmission determined by the position sensor 5.

[0034] The display control unit 124 causes the display unit 6 to display a first image G1 indicating that the detection unit 122 has detected an object in front of the vehicle S. The display control unit 124 causes the display unit 6 to display a second image G2 indicating at least one of the driving status of the vehicle S and the status of the auxiliary equipment installed in the vehicle S. Depending on the status of the vehicle S, the display control unit 124 may display other images different from the first image G1 and the second image G2. Specifically, if the audio equipment installed in the vehicle S is outputting music, the display control unit 124 may display an image on the display unit 6 indicating the title of the song corresponding to the music, or if the driver has been driving the vehicle S for a predetermined time (for example, 2 hours) or longer, the display control unit 124 may display an image on the display unit 6 prompting the driver to take a break.

[0035] The display control unit 124 may, for example, cause one of the first image G1 and the second image G2 to be displayed on the display unit 6, or change the image displayed on the display unit 6 from one image to the other. For example, the display control unit 124 may, when the detection unit 122 detects an object J in front of the vehicle S, cause the display control unit 124 to display the first image G1 on the display unit 6. For example, when the reception unit 121 receives an operation, the display control unit 124 may, for example, change the first image G1 displayed on the display unit 6 to the second image G2a corresponding to the operation, or change the second image G2a displayed on the display unit 6 to the second image G2b or second image G2c corresponding to the operation.

[0036] The display control unit 124 changes the first image G1 displayed on the display unit 6 to the second image G2 corresponding to the predetermined operation when the transmission of the vehicle S is in neutral ("N"), the vehicle speed of the vehicle S is below a predetermined speed, and the brake pedal of the vehicle S is pressed, in response to the reception unit 121 receiving a predetermined operation. The predetermined operation is, for example, an operation to check the vehicle status of the vehicle S.

[0037] For example, if the transmission status included in the transmission information indicates neutral "N", the display control unit 124 changes the first image G1 displayed on the display unit 6, which indicates that the detection unit 122 has detected an object, to a second image G2 corresponding to a predetermined operation received by the reception unit 121, provided that a predetermined condition is met. The predetermined condition is that the vehicle speed included in the vehicle speed information indicates a vehicle speed of less than or equal to a predetermined vehicle speed, and the state of the brake pedal included in the pedal information indicates that it is pressed (i.e., the vehicle S is stopped). The predetermined vehicle speed is, for example, 0 km / h.

[0038] As described above, the display control unit 124 can change the first image G1 displayed on the display unit 6 to the second image G2 when the vehicle S is stopped and the transmission is in neutral ("N"). This allows the display control unit 124 to display the second image G2 corresponding to a predetermined operation received by the reception unit 121 when the vehicle S is temporarily stopped due to traffic congestion or a traffic light and there is no need to display the detection of object J on the display unit 6. As a result, even if there is object J in front of the vehicle S while the vehicle S is stopped, the driver can check the vehicle status of the vehicle S by operating the operation unit 1 after moving the shift lever to the neutral ("N") position.

[0039] The display control unit 124 may hide the first image G1 even if the reception unit 121 has not received a predetermined operation, if the transmission status of the vehicle S is in neutral "N", the vehicle speed of the vehicle S is below a predetermined speed, and the brake pedal of the vehicle S is pressed. For example, if the transmission status included in the transmission information is in neutral "N" and predetermined conditions are met, the display control unit 124 will hide the first image G1 indicating that the detection unit 122 has detected object J, even if the reception unit 121 has not received a predetermined operation. For example, if the position of the shift lever is in the neutral "N" position and predetermined conditions are met, the display control unit 124 will hide the first image G1 even if the detection unit 122 detects object J while the reception unit 121 has not received a predetermined operation.

[0040] By operating as described above, the display control unit 124 can suppress unnecessary notification to the driver that object J has been detected, even when it is in a state where it can display the first image G1, as long as the vehicle S is stopped.

[0041] Even if the vehicle speed is 0 km / h, if the brake pedal is not pressed, the vehicle S may move if there is a slope in the lane in which the vehicle S is stopped. Also, even if the brake pedal is pressed, if the vehicle speed is greater than 0 km / h, the vehicle S is in motion. Therefore, if the transmission status included in the transmission information indicates neutral "N", the display control unit 124 may continue to display the first image G1 on the display unit 6 because a predetermined condition is not met.

[0042] The display control unit 124 may continue displaying the first image G1 even if the reception unit 121 receives a predetermined operation while the display unit 6 is displaying the first image G1, if the vehicle speed of the vehicle S is greater than a predetermined vehicle speed. The display control unit 124 may also continue displaying the first image G1 even if the reception unit 121 receives a predetermined operation while the display unit 6 is displaying the first image G1, if the brake pedal is not pressed. By operating in this manner, the display control unit 124 can prohibit the display of the second image G2 corresponding to a predetermined operation by the driver, even if the shift lever is in the neutral "N" position, if there is a possibility that the vehicle S will move or if the vehicle S is moving.

[0043] Even if the vehicle speed is 0 km / h and the brake pedal is pressed, if the shift lever is in the drive "D" position, the vehicle S may move due to the small amount of brake pedal depression. Therefore, if the transmission state is a gear for forward movement, the display control unit 124 may continue to display the first image G1 even if the reception unit 121 receives a predetermined operation while the display unit 6 is displaying the first image G1. For example, the display control unit 124 continues to display the first image G1 if the transmission state included in the transmission information indicates a gear for forward movement. The gear for forward movement is the number of meshed forward gears or drive "D". By operating in this way, the display control unit 124 can prohibit the display of the second image G2 corresponding to a predetermined operation by the driver and display the first image G1 indicating that object J has been detected when there is a possibility that the vehicle S may move.

[0044] The display control unit 124 may change the first image G1 displayed on the display unit 6 to the second image G2 when the transmission status is reverse "R" or parking "P" and the reception unit 121 has received a predetermined operation while the first image G1 is being displayed on the display unit 6. The display control unit 124 may change the first image G1 displayed on the display unit 6 to the second image G2 when the transmission status included in the transmission information indicates reverse "R" or parking "P" and the reception unit 121 has received a predetermined operation. By operating in this manner, the display control unit 124 can display the second image G2 corresponding to a predetermined operation by the driver when the vehicle S is parked or when the vehicle S is reversing.

[0045] The display control unit 124 may decide whether or not to change the first image G1 displayed by the display unit 6 to the second image G2 corresponding to a predetermined operation received by the reception unit 121 by referring to the display table stored in the storage unit 11. The display table is a table that indicates whether or not to permit the change from the display of the first image G1 to the display of the second image G2, corresponding to the vehicle speed, the state of the brake pedal, and the state of the transmission.

[0046] Figure 3 shows an example of a display table. In Figure 3, the types of transmissions are shown as AT (Automatic Transmission) and MT (Manual Transmission), and the transmission states for AT are shown as "P", "R", "N", and "D", while the transmission states for MT are shown as "R", "N", and "1-6". "1-6" represents the number of engaged forward gears (i.e., gear positions). "ON" shown for the brake pedal indicates that the brake pedal is pressed, and "OFF" indicates that the brake pedal is not pressed. "V" shown for the vehicle speed indicates the vehicle speed S, and "V0" indicates a predetermined vehicle speed (for example, 0 km / h).

[0047] The display control unit 124, for example, by referring to the display table shown in Figure 3, decides whether to change the first image G1 displayed by the display unit 6 to the second image G2 or to continue displaying the first image G1, based on the vehicle speed, brake pedal state, and transmission state acquired by the acquisition unit 123. The display control unit 124 may also decide whether to change the first image G1 displayed by the display unit 6 to the second image G2 or to continue displaying the first image G1, by referring to the display table when the transmission state included in the transmission information acquired by the acquisition unit 123 indicates neutral "N".

[0048] Specifically, the display control unit 124 identifies the vehicle speed "0 km / h" included in the vehicle speed information, the brake pedal state "ON" included in the pedal information, and the transmission state "N" included in the transmission information, all acquired by the acquisition unit 123. By referring to the display table stored in the storage unit 11, the display control unit 124 identifies the "permission" to change from the first image G1 to the second image G2, which corresponds to the vehicle speed "0 km / h", the brake pedal state "ON", and the transmission state "N". Then, based on the identified "permission", the display control unit 124 decides to change the first image G1 displayed by the display unit 6 to the second image G2. By operating in this manner, the display control unit 124 can determine the image to be displayed on the display unit 6 based on the display table stored in the storage unit 11, thus reducing the processing load required for determination.

[0049] The notification unit 125 notifies the driver of the vehicle S of a predetermined state by displaying a notification image on the display unit 6 or emitting a notification sound from the sound output unit 7. The predetermined state is either a first state in which the first image G1 displayed on the display unit 6 can be changed to a second image G2 corresponding to a predetermined operation, or a second state in which the first image G1 indicating that the detection unit 122 has detected object J is hidden, even if the reception unit 121 has not received a predetermined operation.

[0050] The notification unit 125 notifies the driver of vehicle S that, if the transmission of the vehicle is in neutral ("N"), the vehicle speed V of vehicle S is less than or equal to a predetermined vehicle speed V0, and the brake pedal of vehicle S is pressed, then it is possible to change the first image G1 to the second image G2, or to hide the first image G1. For example, if the transmission status included in the transmission information indicates neutral ("N") and predetermined conditions are met, the notification unit 125 notifies the driver of vehicle S that the predetermined conditions have been met because the reception unit 121 has received the operation.

[0051] By operating in this manner, the notification unit 125 makes it easy for the driver to understand that the driver can operate the control unit 1 to display the second image G2. The notification image for notifying the first state and the notification image for notifying the second state may be the same or different. The notification sound for notifying the first state and the notification sound for notifying the second state may be the same or different.

[0052] <Processing sequence in the display control device 10> Figure 4 shows an example of a processing sequence in the display control device 10. The processing sequence shown in Figure 4 is a sequence that shows the operation of deciding whether or not to change the first image G1 displayed by the display unit 6 to the second image G2 corresponding to the operation received by the reception unit 121. Note that the vehicle speed V0 shown in Figure 4 is 0 km / h.

[0053] The reception unit 121 receives a predetermined operation from the operation unit 1 to display the second image G2 (S11). The acquisition unit 123 acquires vehicle speed information from the vehicle speed sensor 3, pedal information from the pedal depression sensor 4, and transmission information from the position sensor 5 (S12). The display control unit 124 identifies the brake pedal state included in the pedal information and the vehicle speed V included in the speed information if the transmission state included in the transmission information is neutral "N" (YES in S13).

[0054] The display control unit 124 permits a change from the first image G1 displayed by the display unit 6 to the second image G2 corresponding to the predetermined operation received by the reception unit 121 if the brake pedal is depressed (depressed as shown in Figure 4) (YES in S14) and the vehicle speed V is less than or equal to the vehicle speed V0 (0 km / h) (YES in S15) (S16). The display control unit 124 prohibits a change from the first image G1 displayed by the display unit 6 to the second image G2 corresponding to the predetermined operation received by the reception unit 121 if the brake pedal is not depressed (NO in S14) or if the vehicle speed V is greater than the vehicle speed V0 (NO in S15) (S18).

[0055] If the transmission status included in the transmission information is not neutral "N" (NO in S13), the display control unit 124 determines whether the transmission status is drive "D". If the transmission status is drive "D" (YES in S17), the display control unit 124 prohibits changing the first image G1 displayed by the display unit 6 to the second image G2 corresponding to the predetermined operation received by the reception unit 121 (S18). If the transmission status is not drive "D" (NO in S17), the display control unit 124 permits changing the first image G1 displayed by the display unit 6 to the second image G2 corresponding to the predetermined operation received by the reception unit 121 (S19).

[0056] The display control device 10 may execute the process in step S11 after executing the processes in steps S12 to S19. That is, in the display control device 10, the reception unit 121 may accept a predetermined operation after the display control unit 124 has decided whether or not to permit the change from the first image G1 to the second image G2. In this case, the display control device 10 repeats the processes in steps S12 to S19 at a predetermined cycle. The predetermined cycle is, for example, a shorter time than the time from when the driver performs an operation on the operation unit 1 to when the driver performs the next operation, and is stored in the storage unit 11. By operating in this manner, the display control device 10 can prohibit the change to the second image G2 corresponding to the next predetermined operation, even if the driver operates the operation unit 1 and moves the shift lever to the drive "D" position immediately after permitting the change from the first image G1 to the second image G2.

[0057] <Effects of the display control device 10> As described above, the display control device 10 includes a reception unit 121 that receives operations on the display unit 6 of the vehicle S, a detection unit 122 that detects an object J in front of the vehicle S, an acquisition unit 123 that acquires vehicle speed information indicating the vehicle speed V of the vehicle S, pedal information indicating the state of the brake pedal operated by the driver of the vehicle S, and transmission information indicating the state of the transmission operated by the driver, and a display control unit 124 that displays the first image G1 on the display unit 6 when the detection unit 122 detects an object J. The display control unit 124 then changes the first image G1 displayed on the display unit 6 to the second image G2 corresponding to the predetermined operation when the transmission is in neutral, the vehicle speed V is less than or equal to a predetermined vehicle speed V0, and the brake pedal is pressed, in response to the reception unit 121 receiving a predetermined operation.

[0058] With the display control device 10 configured in this way, when the vehicle S is stopped and the transmission is in neutral "N", the display control device 10 can change the first image G1 displayed on the display unit 6 to the second image G2 corresponding to a predetermined operation received by the reception unit 121.
