JP 2003-278629 A

  When the shift position of the transmission for transmitting the engine power is at a travelable position such as “D (drive)” and “R (reverse)”, the input for starting the engine is input. It is desirable to avoid the situation that is done. However, in the engine start / stop switch described in Patent Document 1, the shift position is notified only after an input to the switch is performed by the operator. Therefore, the engine start / stop switch described in Patent Document 1 cannot prevent a situation in which an input is made to the switch in a state where the shift position of the transmission is at the travelable position.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an alarm device that notifies that an operation for starting the engine is not input under a state where the shift position is at the travelable position. Is to provide.

  In order to achieve the above object, according to the first aspect of the present invention, a traveling engine is mounted on a vehicle that is started and stopped based on an input to an input means by an operator, and transmits power from the engine. An alarm device for notifying that the shift position of the transmission is at a travelable position where the vehicle can travel; an operating state determining means for determining whether the engine is in an operating state or in a stopped state; The shift position determination means for determining whether or not the shift position is a travelable position, the operator detection means for detecting an operator in the vehicle interior of the vehicle, and the engine state determined by the operating state determination means are in a stopped state The shift position is determined based on the fact that the operator is detected by the operator detection means in a state where the shift position determined by the shift position determination means is a travelable position. There is a notification means for notifying that it is in the travelable position, an alarm device comprising a.

  According to this invention, when an operator is in the vehicle cabin, the operator detection means detects the operator. When the operator is detected in a state where the engine is in the stopped state and the shift position is the travelable position, the notification unit notifies that the shift position is in the travelable position. Accordingly, the operator can be notified that the shift position is at the travelable position before the input to the input means for starting the traveling engine is performed by the operator. Therefore, the alarm device can make a notification that the operation for starting the engine is not input to the input means in a state where the shift position is at the travelable position.

  According to the second aspect of the present invention, it is determined whether or not a vehicle-mounted communication device that communicates with a portable device that can be carried by an operator is in a state that allows communication with the portable device. A communication state determination unit, and the notification unit obtains an operator detection result by the operator detection unit based on a transition from a state in which the portable device and the communication device are not communicable to a state in which communication is possible. Starting and notifying that the shift position is at the travelable position based on the detection result indicating that the operator has been detected.

  According to the present invention, when the operator approaches the vehicle while carrying a portable device that can be carried by the operator, the determination by the communication state determination means is performed from a state in which the portable device and the communication device are not communicable. Transition to a state where communication is possible. Therefore, based on the fact that the portable device and the receiver have transitioned to a communicable state, the notification means may start obtaining the detection result of the operator before the operator gets on the vehicle. it can. As described above, the notification means can perform notification that the shift position is at the travelable position so as to match the operator's boarding in the vehicle. Therefore, in this embodiment, the notification by the notification unit can be surely performed before the operator operates the input unit. Therefore, the alarm device can reliably perform notification that the operation for starting the engine is not input to the input means in a state where the shift position is at the travelable position.

  According to a third aspect of the present invention, the vehicle further includes door opening / closing detection means for detecting the opening / closing state of the door provided in the vehicle, and the notification means is configured such that the door opening / closing state detected by the door opening / closing detection means is in the open state. When the shift is made to the closed state, the fact that the shift position is in the travelable position is notified based on the detection of the operator.

  In this invention, when getting into the vehicle, the operator should perform an operation of opening and closing a door provided in the vehicle. Therefore, when the operator is detected when the door opening / closing state changes from the open state to the closed state, there is a high probability that the operator has entered the vehicle compartment. Thus, by combining with the detection of the open / closed state of the door by the door opening / closing detection means, the accuracy of detection of the operator by the operator detection means is improved. Therefore, the notification performed based on the detection of the operator is accurately applied to the boarding of the operator by the vehicle. Therefore, the notification by the notification unit is surely performed before the operation to the input unit is performed. Therefore, the alarm device can more reliably perform notification that the operation for starting the engine is not input to the input means in a state where the shift position is at the travelable position.

  In the invention according to claim 4, the notification means starts acquiring the detection result of the operator by the operator detection means based on the fact that the engine has changed from the operating state to the stopped state by the input to the input means, Based on the detection result indicating that the operator has been detected, it is notified that the shift position is at the travelable position.

  According to this invention, the notification means for starting the acquisition of the detection result by the operator detection means based on the transition of the engine from the operating state to the stop state is performed every time the engine is stopped. Notification that it is a possible position may be performed. Therefore, a situation in which the operator stops the engine while the shift position remains at the travelable position and the operator leaves the vehicle can be prevented. Thereby, when the operator gets on again, the probability that the shift position is other than the travelable position becomes high. Therefore, the situation where the operation for starting the engine is input to the input means in the state where the shift position is at the travelable position is reliably reduced.

  According to a fifth aspect of the present invention, the vehicle further comprises door opening / closing detection means for detecting the opening / closing state of the door provided in the vehicle, and the notification means is configured such that the door opening / closing state detected by the door opening / closing detection means is in the closed state. Until the shift to the open state, the notification that the shift position is at the travelable position is stopped.

  Some operators may change the shift position to a position other than the travelable position after stopping the engine with the shift position remaining at the travelable position. Such an operator may feel annoying notification started immediately after the engine is stopped.

  Therefore, in the present invention, the notification of the shift position by the notification means is stopped until the door open / close state changes from the closed state to the open state. When getting off the vehicle, the operator should open the door. Therefore, if it is a stop until it changes to an open state, the alert | report that the shift position exists in a driving | running | working position can be reliably started in the state in which an operator exists in a vehicle interior. As described above, the alarm device can notify that the operation for starting the engine is not input to the input means in a state where the shift position is at the travelable position while allowing a difference in the operation procedure by the operator. it can.

  In the invention according to claim 6, it is determined whether or not a vehicle-mounted communication device that communicates with a portable device that can be carried by an operator is in a state that allows communication with the portable device. A communication state determination unit, and the notification unit transitions from a state in which the portable device and the communication device are communicable to a state in which communication is not possible when the notification that the shift position is in the travelable position is once started. Based on this, the notification is finished.

  According to the present invention, when the operator leaves the vehicle while carrying the portable device, the determination by the communication state determination unit is changed from a state where the portable device and the communication device can communicate to a state where communication is not possible. Transition to. Therefore, based on the fact that the portable device and the receiver are in a state where communication is not possible, the notification means ends the notification in accordance with the fact that the operator who is the notification target is no longer near the vehicle. Can do. In this way, by terminating the notification by the notification means at an appropriate time, the alarm device can perform an operation of starting the engine in a state where the shift position is at the travelable position while reducing unnecessary power consumption. It is possible to make a notification so that it is not input to the input means.

  In the seventh aspect of the present invention, the operator detection means has a seating detection unit that detects an operator seated in the driver's seat in the passenger compartment, and the notification means is seated by an operator seated in the driver's seat. Based on what was detected by the detection part, it notifies that a shift position exists in a driving | running | working possible position.

  Generally, the device for changing the shift position is disposed in the vicinity of the driver's seat so that it can be easily operated by an operator seated in the driver's seat. Therefore, by detecting the operator seated in the driver's seat by the seating detection unit and making notification based on the detection result, the operator who has received the notification immediately changes the shift position to a position other than the travelable position. The operation to change can be performed. As described above, the alarm device is configured to detect an operator in a state capable of accurately dealing with the notification, and the alarm device receives an operation for starting the engine while leaving the shift position at the travelable position. It is possible to reliably reduce the occurrence of accidents.

  The invention according to claim 8 is characterized in that the notifying means displays an alarm image for notifying that the shift position is in the travelable position on the display means for displaying an image toward the driver's seat. .

  According to the present invention, the alarm image for notifying that the shift position is in the travelable position is displayed on the display means directed to the driver's seat, so that the content of the notification can be accurately transmitted to the operator. become. Therefore, the occurrence of a situation in which an operation for starting the engine is input while the shift position remains at the travelable position is reliably reduced.

  In addition, an alarm image displayed by the display means directed to the driver's seat is obtained by combining the configuration according to claim 7 for detecting an operator sitting in the driver's seat with the invention according to claim 8. Is easily visible to an operator sitting in the driver's seat. As a result, the contents of the notification are more accurately transmitted to the operator. Therefore, the occurrence of a situation in which an operation for starting the engine is input with the shift position remaining at the travelable position is further reliably reduced.

It is the flowchart in which the process implemented by a meter control circuit by the accessory power supply of a vehicle changing to an ON state was shown.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a system configuration of a combination meter 100 having a function of an alarm device according to the present invention. FIG. 2 is a front view of the combination meter 100. The combination meter 100 is accommodated in an instrument panel provided in the vehicle interior of the vehicle, and is arranged with the front side shown in FIG. 2 facing the driver's seat.

  The combination meter 100 includes a display 30 and a meter control circuit 20. The display 30 is a dot matrix type transmissive liquid crystal panel having a plurality of pixels arranged in a matrix. The display 30 displays various information related to vehicle information as images by driving each pixel in accordance with a drive signal from the meter control circuit 20.

  The meter control circuit 20 includes a processor that performs various types of arithmetic processing, a flash memory that stores information about programs and vehicles used for the arithmetic processing, and a RAM that functions as a calculation work area. In addition, the meter control circuit 20 has a drive circuit (not shown) that outputs a drive signal for controlling each pixel of the display 30 to the display 30. The meter control circuit 20 executes a program by a processor to acquire information necessary for performing notification, which will be described later, and determine and output a signal to a connected device.

  The meter control circuit 20 is electrically connected to various devices mounted on the vehicle. The meter control circuit 20 is connected to the vehicle control device 57, the engine control device 51, the ignition switch 53, the seating sensor 55, the door control device 59, the shift lever position sensor 61, and the like, and acquires information from these components. In addition, the meter control circuit 20 is connected to the audio device 40, the alarm sound generation device 43, and the like, and outputs a control signal thereto.

  The vehicle control device 57 is configured mainly with a computer or the like, and performs various arithmetic processes for controlling the vehicle in an integrated manner. The vehicle control device 57 is connected to an on-vehicle radio wave key computer 58b. The radio wave key computer 58b communicates with a radio wave key 58a that can be carried by an operator of a vehicle such as a driver. The radio key computer 58b has a plurality of antennas (not shown) for receiving encrypted unique key data transmitted from the radio key 58a. The radio key computer 58b collates key data transmitted from the radio key 58a with previously stored key data. When the key data collation is established with the radio wave key 58a, the radio wave key computer 58b outputs a collation establishment signal indicating that the collation is established to the vehicle control device 57. By acquiring the verification establishment signal through the vehicle control device 57, the meter control circuit 20 determines whether or not the radio key computer 58b is in a state where communication with the radio key 58a is possible.

  The engine control device 51 is configured mainly by a computer or the like, and performs various calculations for controlling a gasoline engine for traveling. The engine control device 51 starts and stops the gasoline engine based on an input to the ignition switch 53 by the driver. The engine control device 51 acquires a vehicle speed signal indicating the traveling speed of the vehicle for controlling the gasoline engine. By acquiring the vehicle speed signal through the engine control device 51, the meter control circuit 20 determines whether the vehicle is in a stopped state or a traveling state.

  The ignition switch 53 is a push-type switch that is installed in the vicinity of the driver's seat in the passenger compartment and receives a pressing operation by the driver. The gasoline engine is started and stopped when a pressing operation is input to the ignition switch 53 by the driver. The ignition switch 53 outputs an ignition signal based on an input from a driver or the like. By acquiring this ignition signal, the meter control circuit 20 determines whether the engine is in an operating state or a stopped state.

  The seating sensor 55 is formed in a seat shape and is embedded in the seat surface portion of the driver's seat in the passenger compartment. The seating sensor 55 outputs a seating signal indicating whether or not the driver is seated on the driver seat based on the bending of the seat surface portion caused by the driver sitting on the driver seat. By receiving the seating signal output from the seating sensor 55, the meter control circuit 20 detects the driver seated in the driver's seat in the passenger compartment.

  The door control device 59 has a switch that is switched ON and OFF by opening and closing each door provided in the vehicle. The switch of the door control device 59 is installed on the periphery of the opening on the vehicle body side so as to be pressed by the closed door. The door control device 59 outputs a door opening / closing signal indicating whether the door is open or closed by determining whether the switch is ON or OFF. Of the door opening / closing signals output from the door control device 59, for example, by obtaining the door opening / closing signal provided near the driver's seat, the meter control circuit 20 opens / closes the door near the driver's seat. Detect state.

  The shift lever position sensor 61 is a position sensor for detecting the shift position of a shift lever (not shown). The shift lever is provided, for example, in a center console provided between the driver's seat and the passenger seat so that it can be easily operated by a driver sitting in the driver's seat. The shift lever is an input device for operating a transmission that transmits power from a gasoline engine to a drive system. The shift lever is provided with a plurality of shift positions such as “P (parking)”, “R (reverse)”, “N (neutral)”, and “D (drive)”. When the shift position is either “D” or “R”, the power transmitted to the drive system through the transmission causes the vehicle to travel by rotating the wheels. The shift lever position sensor 61 outputs a shift position signal indicating the shift position selected by the shift lever. By acquiring the shift position signal output by the shift lever position sensor 61, the meter control circuit 20 determines whether or not the shift position is located in one of “D” and “R”. In this embodiment, among the plurality of shift positions, “D” and “R” correspond to “travelable positions” recited in the claims.

  The audio device 40 and the alarm sound generation device 43 are both connected to the speaker 42. The audio device 40 drives the speaker 42 to output music, voice, and the like from the speaker 42. Further, the alarm sound generator 43 drives the speaker 42 to output an alarm sound having a predetermined frequency from the speaker 42.

  The combination meter 100 having the above configuration is based on the fact that the driver is detected in a state where the gasoline engine is in a stopped state and the shift position of the shift lever is in either “D” or “R”. Informs about the shift position. Hereinafter, a process in which the combination meter 100 acquires information from each device mounted on the vehicle and performs notification of the shift position will be described based on FIGS. 3 and 4 with reference to FIG. 1.

  Here, the notification by the combination meter 100 is performed by displaying the alarm image 31 on the display 30 (see FIG. 2) and sound or alarm sound output from the speaker 42 in this embodiment. The alarm image 31 includes, for example, an icon 31a that prompts the driver to call attention, and a character portion 31b that indicates the notified content in characters. Further, for example, a sound indicating a specific notification content “the shift lever remains in the drive range” is output from the speaker 42.

  First, the process shown in FIG. 3 will be described. The process shown in FIG. 3 is performed by the meter control circuit 20 when the driver carrying the radio wave key 58a approaches the parked vehicle and gets into the vehicle. More specifically, when the driver approaches the parked vehicle with the radio key 58a carried, the radio key computer 58b and the radio key 58a shift from a state where they cannot communicate with each other to a state where they can communicate. . Thereby, the meter control circuit 20 acquires a verification establishment signal indicating that the state has changed to a communicable state through the vehicle control device 57. The meter control circuit 20 detects establishment of communication and collation between the radio key computer 58b and the radio key 58a based on the acquired collation establishment signal, and starts the processing shown in FIG. 3 based on the detection of establishment of communication.

  In S101, based on the vehicle speed signal acquired through the engine control device 51, it is determined whether or not the vehicle is stopped. If it is determined in S101 that the vehicle is in a stopped state, the process proceeds to S102. On the other hand, if it is determined in S101 that the vehicle is in a traveling state, the process is terminated.

  In S102, based on the ignition signal acquired from the ignition switch 53, it is determined whether the gasoline engine is in an operating state or a stopped state. If it is determined in S102 that the state of the gasoline engine is stopped, the process proceeds to S103. On the other hand, if it is determined in S102 that the state of the gasoline engine is in the operating state, the process is terminated.

  In S103, based on the door opening / closing signal indicating the door opening / closing state acquired from the door control device 59, whether or not the door has changed from the open state to the closed state, that is, the door opening / closing operation by the driver getting into the vehicle. It is determined whether or not. In S103, when it is determined that the door has changed from the open state to the closed state by the opening / closing operation of the door by the driver, the process proceeds to S104. On the other hand, when it is determined that the door opening / closing operation by the driver has not been completed and the door has not changed from the open state to the closed state, the determination in S103 is repeated. Thereby, the notification about the shift position is performed only when the open / closed state of the door changes from the open state to the closed state.

  In S104, based on the seating signal from the seating sensor 55, it is determined whether or not the driver is seated in the driver's seat, that is, whether or not the driver to be notified is detected in the passenger compartment. If it is determined in S104 that the driver is seated in the driver's seat, the process proceeds to S105. On the other hand, if it is determined in S104 that the driver is not seated in the driver's seat, the determination in S104 is repeated.

  In S105, based on the shift position signal indicating the shift position acquired from the shift lever position sensor 61, it is determined whether or not the current shift position is in a travelable position such as “D” and “R”. If it is determined in S105 that the shift position is at the travelable position, the process proceeds to S106. On the other hand, if it is determined in S105 that the shift position is at any one of “P” and “N” other than the travelable position, the process proceeds to S108.

  In S106, in order to notify that the shift position is in the travelable position, a drive signal and a control signal for performing notification are output to the display 30, the audio device 40, and the alarm sound generating device 43. Based on the drive signal from the meter control circuit 20, the display 30 starts displaying the alarm image 31. Further, the audio device 40 temporarily reduces the volume of music or the like currently being played based on the control signal from the meter control circuit 20. Then, the audio device 40 outputs sound for notification through the speaker 42. Further, the alarm sound generation device 43 outputs a predetermined alarm sound through the speaker 42 together with the output of the sound by the audio device 40.

  In S107, based on the collation establishment signal acquired through the vehicle control device 57, it is determined again whether communication and collation between the radio key 58a and the radio key computer 58b are established. If it is determined in S107 that communication has been established, the process returns to S105, and the processes of S105 to S107 are repeated. On the other hand, if it is determined in S107 that communication is not established, the process proceeds to S108.

  In S108, when the notification that the shift position is in the travelable position has been started, a process for ending the notification is performed, and the process is terminated. Specifically, the drive signal output to the display 30 is stopped and a control signal for terminating the notification is output to the audio device 40 and the alarm sound generator 43. Thereby, the display 30 ends the display of the alarm image 31. Further, the audio device 40 and the warning sound generation device 43 end the notification using the voice and the warning sound.

  With the above processing, in a state where the vehicle is in a stopped state and the shift position is a travelable position, the combination meter 100 is based on the fact that the driver is detected in the passenger compartment when the driver enters the vehicle. Informing that the shift position is at the travelable position. Thereby, the driver | operator can receive the alert | report about the said shift position, when getting into the parked vehicle with the shift position remaining in the driving | running | working possible position.

  Next, the process shown in FIG. 4 will be described. The process shown in FIG. 4 is performed by the meter control circuit 20 when the accessory (ACC) power source of the vehicle changes from the OFF state to the ON state based on the operation of the driver or the like.

  In S201, based on the vehicle speed signal acquired through the engine control device 51, it is determined whether or not the vehicle is stopped. If it is determined in S201 that the vehicle is in a stopped state, the process proceeds to S202. On the other hand, if it is determined in S201 that the vehicle is in a traveling state, the determination in S201 is repeated.

  In S202, based on the ignition signal acquired from the ignition switch 53, it is determined whether the gasoline engine is in an operating state or a stopped state. If it is determined in S202 that the gasoline engine is in the stopped state, the process proceeds to S203. On the other hand, if it is determined in S202 that the gasoline engine is in an operating state, the process returns to S201, and the determinations in S201 and S202 are repeated.

  In S203, the acquisition of the detection result of the driver is started based on the fact that the gasoline engine has changed from the operating state to the stopped state by the input to the ignition switch 53. In S203, based on the seating signal from the seating sensor 55, it is determined whether or not the driver is seated in the driver's seat, that is, whether or not the driver to be notified is detected in the passenger compartment. . If it is determined in S203 that the driver is seated in the driver's seat, the process proceeds to S204. On the other hand, if it is determined in S203 that the driver is not seated in the driver's seat, the process is terminated because there is a high probability that the driver to be notified has already left the vehicle.

In S204, based on the collation establishment signal acquired through the vehicle control device 57, it is determined whether communication and collation between the radio key 58a and the radio key computer 58b are established. If it is determined in S204 that communication is established, the process proceeds to S205. On the other hand, if it is determined in S204 that communication is not established, the process proceeds to S208.

  In S205, based on the door open / close signal indicating the door open / close state acquired from the door control device 59, whether or not the door has changed from the closed state to the open state, i.e., for the driver to get off, It is determined whether or not an operation has been performed. In S205, when it is determined that the door has changed from the closed state to the open state due to the opening operation of the door by the driver, the process proceeds to S206. On the other hand, when it is determined that the door opening operation by the driver is not completed and the door remains closed, the determination in S205 is repeated. Thus, after the gasoline engine is stopped, the notification of the shift position is temporarily stopped until the door open / close state changes from the closed state to the open state.

  In S206, based on the shift position signal indicating the shift position acquired from the shift lever position sensor 61, it is determined whether or not the current shift position is in a travelable position such as “D” and “R”. If it is determined in S206 that the shift position is at the travelable position, the process proceeds to S207. On the other hand, if it is determined in S206 that the shift position is at any one of “P” and “N” other than the travelable position, the process proceeds to S208.

  In S207, in order to start notification that the shift position is at the travelable position, the same process as in S106 described above is performed, and the process returns to S204. Thereby, the determination of S204 to S206 is repeated.

  If it is determined in S204 that the radio wave key 58a and the radio wave key computer 58b have shifted to a state where communication is not possible, or if it is determined in S206 that the shift position has been changed to a position other than the travelable position, the process proceeds to S208. move on. In S208, a process for ending the notification is performed as in S108 described above.

  With the above processing, when the driver stops the gasoline engine while leaving the shift position at the travelable position and further opens the door to get out of the vehicle, the combination meter 100 travels at the shift position. Notify that it is in a possible position. As a result, a situation in which the driver leaves the vehicle while the shift position remains at the travelable position can be prevented.

  According to this embodiment described so far, when the driver is detected in a state where the gasoline engine is stopped and the shift position is the travelable position, the combination meter 100 has the shift position at the travelable position. Inform you. Thus, the driver is informed that the shift position is in the travelable position before the input to the ignition switch 53 for starting the gasoline engine is performed by the operator. Therefore, the combination meter 100 can notify that the operation for starting the gasoline engine is not input to the ignition switch 53 in a state where the shift position is at the travelable position.

  In addition, according to the present embodiment, when the driver approaches the vehicle while carrying the radio wave key 58a, the meter control circuit 20 starts the process shown in FIG. 3 including the detection of the driver. Thus, the meter control circuit 20 can start obtaining the detection result of the driver before the driver gets on the vehicle. As described above, the meter control circuit 20 can notify that the shift position is at the travelable position so as to match the driver's boarding in the vehicle. Therefore, the notification about the shift position can be surely performed before the driver operates the ignition switch 53.

  Further, when getting into the vehicle, the driver should perform an operation of opening and closing a door provided in the vehicle. Therefore, when the driver is detected when the door open / close state changes from the open state to the closed state, there is a high probability that the driver has entered the passenger compartment. In this way, the detection accuracy of the driver is improved by being combined with the detection of the open / closed state of the door. Therefore, the notification performed based on the driver's detection is accurately applied to the driver's boarding in the vehicle. Therefore, the notification by the combination meter 100 is surely performed before the operation to the ignition switch 53 is performed.

  As described above, the combination meter 100 can reliably perform notification that the operation for starting the engine is not input to the ignition switch 53 in a state where the shift position is at the travelable position.

  In addition, according to the present embodiment, the process shown in FIG. 4 is performed, so that the driver stops the gasoline engine while leaving the shift position at the travelable position, and further leaves the vehicle. Can be prevented beforehand. Therefore, when the driver gets on the vehicle again, there is a high probability that the shift position is other than the travelable position. Therefore, the situation where the operation for starting the gasoline engine is input to the ignition switch 53 while the shift position is at the travelable position is reliably reduced.

  In addition, according to the present embodiment, the meter control circuit 20 terminates the notification when the radio wave key 58a and the radio wave key computer 58b are in a state where communication is not possible. Even when the shift position is not changed to a position other than the travelable position, the combination meter 100 can finish the notification in accordance with the fact that the driver who is the target of notification is no longer near the vehicle. In this way, by terminating the notification of the shift position at an appropriate time, the combination meter 100 starts the gasoline engine in a state where the shift position is at the travelable position while reducing unnecessary power consumption. It is possible to reduce the situation in which the operation to be input is input to the ignition switch 53.

  In addition, according to the present embodiment, the meter control circuit 20 detects a driver seated in the driver's seat and performs notification based on the detection result. Therefore, the driver who has received the notification can immediately change the shift position to “P” by operating a shift lever provided at a position where the driver can easily operate from the driver's seat. As described above, an operation for starting the gasoline engine in a state in which the shift position remains in the travelable position is input by detecting the driver in a state that can accurately cope with the notification. Things are definitely reduced.

  Furthermore, according to the present embodiment, the notification of the shift position is temporarily stopped until the door is opened after the gasoline engine is stopped. Some drivers may change the shift position to “P” after stopping the gasoline engine while leaving the shift position at the travelable position. Therefore, it is possible to prevent such a situation that the driver feels annoying the notification. In addition, when getting out of the vehicle, the driver should open the door. Therefore, if it is a temporary stop until it changes to an open state, the notification that the shift position is in the travelable position can be surely started while the driver is in the vehicle compartment. As described above, the combination meter 100 can notify that the operation for starting the gasoline engine is not input in a state where the shift position is at the travelable position while allowing a difference in the operation procedure by the driver.

  Furthermore, according to the present embodiment, the alarm image 31 including the character portion 31b is displayed on the display 30, so that the content of the notification is accurately transmitted to the driver. Therefore, the situation where the operation for starting the gasoline engine is input while the shift position remains at the travelable position is reliably reduced. In addition, the alarm image 31 displayed by the display 30 directed to the driver's seat is easily visible to the driver sitting on the driver's seat. Therefore, the content of the notification is transmitted more accurately to the driver. Therefore, a situation in which an operation for starting the gasoline engine in a state where the shift position remains at the travelable position is further reliably reduced.

  In the present embodiment, the meter control circuit 20 has the “operation state determination means”, “shift position determination means”, “operator detection means”, “notification means”, “communication state determination means” recited in the claims. ”,“ Door open / close detection means ”, and“ sitting detection section ”, the display 30 corresponds to“ notification means ”and“ display means ”described in the claims, and the ignition switch 53 corresponds to the claims. The radio key 58a corresponds to the "portable device" described in the claims, the radio key computer 58b corresponds to the "communication device" described in the claims, The gasoline engine corresponds to the “engine” described in the claims, and the combination meter 100 corresponds to the “alarm device” described in the claims.

  In the above embodiment, the meter control circuit 20 starts the process shown in FIG. 3 when communication and verification between the radio key 58a and the radio key computer 58b are established. As a result, when the driver gets into the vehicle, the shift position can be notified. In addition, in the above embodiment, the meter control circuit 20 starts the process shown in FIG. 4 when the ACC power supply of the vehicle is turned on. Thus, when the driver stops the gasoline engine, the shift position can be notified. However, the meter control circuit may be configured to perform only one of the process shown in FIG. 3 and the process shown in FIG. Alternatively, the meter control circuit may perform processing corresponding to S203 to S208 when the gasoline engine is stopped based on the ignition signal from the ignition switch 53.

  In the above embodiment, “D” and “R” correspond to the travelable positions of the shift lever. However, depending on the structure of the shift lever, for example, “L (low)” and “S (sports)” may be provided as shift positions at which power can be transmitted. In such a case, “L” and “S” also correspond to the travelable positions. Further, when the transmission mounted on the vehicle is not an automatic transmission as in the above embodiment but a manual transmission that manually changes the gear ratio, a shift position other than “N” corresponds to the travelable position. .

  In the above embodiment, when the driver gets into the vehicle, the shift position is not notified unless the door is once opened and closed. Further, when the gasoline engine was stopped, the shift position was not notified until the door was opened. However, the determination regarding the opening / closing of these doors (S103 in FIG. 3 and S205 in FIG. 4) may be omitted.

  In the above embodiment, the radio wave key 58a is applied as a “portable device” described in the claims, which is configured to detect the approach of the driver to the vehicle and the separation of the driver from the vehicle. It was. However, the device used as the “portable device” is not limited to the radio wave key 58a. For example, even if the approach and separation of the driver are detected by performing wireless communication according to, for example, Bluetooth (registered trademark) standard between the mobile phone carried by the driver and the communication device mounted on the vehicle, Good.

  In the above-described embodiment, the notification once started is continued until the shift position is changed from the travelable position or the communication between the radio key 58a and the radio key computer 58b is interrupted. However, the meter control circuit may count the elapsed time from the start of notification and terminate the notification when a specific time has elapsed. Alternatively, the meter control circuit may end the notification when triggered by an operation other than the radio wave key 58a, for example, a central door lock or the like.

  In the above embodiment, the meter control circuit 20 detects the driver based on the seating signal from the seating sensor 55 provided on the seat surface portion of the driver's seat. However, the configuration for detecting the driver in the passenger compartment is not limited to the above embodiment.
