Abstract

PROBLEM TO BE SOLVED: To make it possible to notify a driver of a traveling standby state in more effective manner than in the conventional case.SOLUTION: A traveling standby state notification device judges whether or not the traveling standby state exists in which a vehicle starts to travel upon an accelerator operation of a driver of the vehicle (step 110), judges whether or not a predetermined period of time elapses from the beginning of the traveling standby state upon the judgement that the traveling standby state exists and judges, based on the result, whether or not a dangerous state exists in which the driver is not aware of the traveling standby state (step 130), and notifies the driver of the traveling standby state of the vehicle based on the judgement that the dangerous state exists(steps 150 to 170).

Description

  The present invention relates to a program for running standby state notifying device required and running standby state notifying device required.

  In an electric vehicle (EV) that travels using an electric motor as a power source and an idling stop vehicle in which the operation of the internal combustion engine (engine) stops when the vehicle is stopped, no idling sound is generated in the travel standby state, and therefore the driver is in the travel standby state. There was a risk that the user would accidentally operate the accelerator without noticing that the vehicle would start suddenly.

  As a countermeasure, Patent Document 1 proposes a technique for determining whether or not a vehicle is in a travel standby state and periodically generating a predetermined musical sound in the passenger compartment immediately after entering the travel standby state.

JP 2004-268625 A

  However, according to the study by the present inventor, even if the musical sound is periodically generated immediately after entering the traveling standby state, it does not necessarily mean that it is useful to make the driver notice that the traveling standby state is present. is not.

  For example, immediately after the driver operates the switch to shift the vehicle from the parked state to the traveling standby state, the driver knows that the driver is in the traveling standby state. There is no need to generate them periodically.

  If the musical sound is generated even when it is not necessary for the driver to recognize that the vehicle is in the standby state, the driver is uncomfortable, and the quietness in the vehicle is also impaired.

  In view of the above points, an object of the present invention is to provide a technique that makes a driver notice that the vehicle is in a travel standby state more effectively than before.

  In order to achieve the above object, the invention according to claim 1 is a travel standby state notifying device that is mounted on a vehicle and notifies a driver that the vehicle is in a travel standby state, wherein the driver of the vehicle When it is determined that the operation standby state determination means (110) for determining whether or not the vehicle is in a travel standby state in which the vehicle starts to move and the travel standby state determination means (110) are determined to be in the travel standby state, A dangerous state in which the driver is unaware of the travel standby state based on whether a predetermined time has elapsed since the start of the travel standby state or based on a detection result of a sensor that detects the driver's behavior Based on the danger state determination means (130) for determining whether or not the vehicle is in danger state and the danger state determination means (130) has determined that the vehicle is in the dangerous state, Notifying means for notifying the driver that traveling is in the standby state (150～170,13), a travel standby state notification apparatus equipped with.

  As described above, the travel standby state notification device is a sensor that detects the driver's action based on whether a predetermined time has elapsed from the start of the travel standby state after the vehicle enters the travel standby state. Based on the detection result, it is determined whether or not the driver is in a dangerous state that is not aware of the traveling standby state. If it is determined that the driver is in the dangerous state, the driver is notified that the vehicle is in the traveling standby state. It is like that. Therefore, the possibility that the driver is wastefully notified that the vehicle is in the travel standby state is reduced even in a situation where the driver travel standby state is conscious. Therefore, it is possible to make the driver notice that the vehicle is in the traveling standby state more effectively than before.

  The invention according to claim 2 is the travel standby state notifying device according to claim 1, wherein the notifying means (150 to 170, 13) vibrates a vibration part attached to a driver's seat of the vehicle. By doing so, the driver is notified that the vehicle is in the travel standby state.

  In this way, the notification using the vibration of the driver's seat can give the driver a stimulus similar to the vibration generated during idling of the vehicle having the internal combustion engine, so that the driver is in the traveling standby state. This can be empirically recognized, and therefore, the possibility of forgetting that the vehicle is in the standby state for the operation despite the notification is reduced.

  The invention according to claim 3 is the travel standby state notifying device according to claim 1 or 2, wherein the notifying means (150 to 170, 13) indicates that the vehicle speed of the vehicle has exceeded a predetermined threshold. Based on the above, the notification that the vehicle is in the travel standby state is terminated.

  By doing so, it is possible to enable comfortable driving by stopping the warning and stopping the unnecessary warning notification to the driver when it can be estimated that the vehicle has left the standby state and has entered the driving state.

  According to a fourth aspect of the present invention, in the travel standby state notification device according to any one of the first to third aspects, the dangerous state determination means (130) is the travel standby state determination means (110). Whether or not the driver is not aware of the travel standby state based on whether or not a predetermined time has elapsed since the start of the travel standby state. The predetermined time is longer when the vehicle has traveled since the last time the main switch was turned on than when the vehicle has not traveled since the last time the main switch was turned on. It is characterized by.

  The travel standby state in the case where the vehicle is not traveling since the last turn-on of the main switch occurs in a time period from when the driver gets on the vehicle until the start of travel. The travel standby state when the vehicle has been played since the last turn-on of the main switch occurs when the vehicle is temporarily stopped, such as waiting for a signal. When comparing the former with the latter, the latter tends to be more tensioned by the driver, so the time until the vehicle forgets that the vehicle is in the travel standby state often becomes longer.

  Therefore, as described above, the predetermined time is longer when the vehicle has traveled since the last time the main switch was turned on than when the vehicle has not traveled since the last time the main switch was turned on. Thus, it is possible to further reduce the possibility of wasteful notification of the travel standby state.

  According to a fifth aspect of the present invention, there is provided a program used for a travel standby state notification device that is mounted on a vehicle and that notifies the driver that the vehicle is in a travel standby state in which the vehicle starts to move when the driver of the vehicle performs an accelerator operation. The travel standby state notifying device determines whether or not the driver of the vehicle is in the travel standby state by means of travel standby state determination means (110), and the travel standby state determination means (110) is the travel standby state. When it is determined that the vehicle is in a state, the driver is on the basis of whether or not a predetermined time has elapsed since the start of the traveling standby state, or based on a detection result of a sensor that detects the driver's behavior. A dangerous state determining means (130) for determining whether or not the dangerous state is unaware of the state, and the dangerous state determining means (130) In a Based upon the determined, a program to function as a notification means (150～170,13) for notifying the driver that the vehicle is in the running standby state. As described above, the features of the present invention can be understood as a program.

  In addition, the code | symbol in the bracket | parenthesis in the said and the claim shows the correspondence of the term described in the claim, and the concrete thing etc. which illustrate the said term described in embodiment mentioned later. .

It is a figure which shows the structure of the vehicle-mounted system which concerns on embodiment of this invention. It is a flowchart which shows the processing content of a dangerous condition estimation part. It is a figure which shows the example of the operation timing of a driving | running | working standby state notification apparatus.

  Hereinafter, an embodiment of the present invention will be described. FIG. 1 shows a configuration of an in-vehicle system according to the present embodiment. This in-vehicle system is mounted on a vehicle and includes a travel standby state notification device 1, a main switch 2, a side brake sensor 3, a brake pedal sensor 4, a vehicle speed sensor 5, a seat vibration unit 6, a sound generation unit 7, and a display unit 8. Yes. This vehicle is an electric vehicle. An electric vehicle is a vehicle that does not include an engine that is an internal combustion engine and that travels with a driving force generated by an electric motor.

  The travel standby state notification device 1 is a device that is mounted on a vehicle and notifies a driver that the vehicle is in a travel standby state as necessary. The running standby state refers to a state in which the vehicle starts moving when the vehicle is stopped and the driver of the vehicle performs an accelerator operation. In such a state, if the driver performs the accelerator operation unintentionally, the vehicle may unintentionally start suddenly.

  In particular, in an electric vehicle, such a situation is likely to occur. Because, in an electric vehicle that does not have an engine that is an internal combustion engine, engine idling noise does not occur, and creep force (force to start running the vehicle without operating the accelerator if the brake pedal is removed) is generated. This is because the vehicle does not start even if the brake pedal is not depressed.

  The main switch 2 is a switch for switching on / off of the main power supply of the vehicle. When the main switch 2 is turned on, power can be supplied to the electric motor, and when the main switch 2 is turned off, power cannot be supplied to the electric motor.

  The side brake sensor 3 is a sensor that detects an operating state of the side brake of the vehicle and outputs the detected state to the travel standby state notification device 1. Specifically, either the ON state where the side brake is applied or the release state where the side brake is released is detected, and a detection result detection signal is output to the travel standby state notification device 1.

  The brake pedal sensor 4 detects whether or not the brake pedal of the vehicle is depressed, and outputs a detection result detection signal to the travel standby state notification device 1. The vehicle speed sensor 5 detects the traveling speed of the vehicle, and outputs a detection result detection signal to the traveling standby state notifying device 1.

  The seat vibration unit 6 is attached to each seat of the vehicle (driver's seat, front passenger seat, rear seat, etc.) and vibrates in accordance with control from the travel standby state notification device 1, thereby transmitting vibrations to the passengers seated in the seat. .

  The sound generation unit 7 is a device (for example, an amplifier and a speaker) that outputs various sounds to the vehicle interior in accordance with control from the travel standby state notification device 1. The display unit 8 is an image display device that displays characters or images on the driver in accordance with control from the travel standby state notification device 1.

  Here, the configuration of the travel standby state notification device 1 will be described in more detail. The travel standby state notification device 1 is a microcomputer including a CPU, a RAM, a ROM, a flash memory, and the like, and the travel standby state notification device 1 is described later when the CPU executes a program recorded in the ROM and the flash memory. The process to do is realized.

  When the processing realized by the travel standby state notification device 1 is classified by function, it can be divided into a timer unit 11, a dangerous state prediction unit 12, and a warning control unit 13, as shown in FIG.

  When the time is set from the dangerous state prediction unit 12, the timer unit 11 waits until the set time expires, and when it has expired, realizes a process of outputting an expiration signal to the dangerous state prediction unit 12.

  When the vehicle is in the travel standby state based on the signals from the main switch 2, the side brake sensor 3, the vehicle speed sensor 5, and the timer unit 11, the dangerous state prediction unit 12 is not aware of the travel standby state. It is determined whether or not it is in a dangerous state, and when it is determined that it is in a dangerous state, the warning signal to the warning control unit 13 is turned from OFF to ON.

  When the warning signal from the dangerous state prediction unit 12 is on, the warning control unit 13 vibrates the seat vibration unit 6 only for the driver's seat, outputs sound to the sound generation unit 7, or displays characters on the display unit 8. Alternatively, an image is displayed to notify the driver that the vehicle is in a travel standby state.

  FIG. 2 is a flowchart showing details of the process of the dangerous state prediction unit 12. The dangerous state prediction unit 12 may always execute the processing shown in FIG. 2 regardless of whether the main switch 2 is turned on or off, or starts executing when the main switch 2 is turned on. It may be.

  First, in step 110, it is determined whether or not the vehicle is in a travel standby state. The running standby state refers to a state in which the vehicle starts moving when the vehicle is stopped and the driver of the vehicle performs an accelerator operation.

  This determination is made based on whether or not a predetermined standby condition is satisfied. The standby condition is a condition that “the main switch 2 is on, the vehicle is stopped, and the side brake is in the released state”. Whether or not the side brake is in the released state is determined based on a detection signal from the side brake sensor 3. Whether or not the vehicle is stopped is determined by calculating a vehicle speed based on a detection signal from the vehicle speed sensor 5 and determining whether or not the calculated vehicle speed is zero. Whether or not the main switch 2 is on can be specified based on a detection signal from the main switch 2, but the processing shown in FIG. 2 is started when the main switch 2 is turned on. If it is, it is sufficient to determine that the main switch 2 is always on, without using the detection signal from the main switch 2.

  In addition, in the vehicle provided with the automatic transmission, when the parking range is selected as the drive range, the vehicle cannot travel. However, the vehicle according to the present embodiment does not have such a mechanism.

  Then, the determination in step 110 is repeated until it is determined that the vehicle is in the travel standby state. When it is determined that the vehicle is in the travel standby state, the process proceeds to step 120.

  In step 120, a predetermined time T (for example, 30 seconds) is set in the timer unit 11. This time T is the time that the driver forgets to be in the travel standby state even when the vehicle is in the travel standby state, and is preliminarily determined empirically and stored in the ROM or flash memory. Use.

  Then, the timer unit 11 starts from the time when the time T is set, and waits until the time elapsed from the start time reaches the set time T, that is, until the set time T expires. An expiration signal is output to the dangerous state prediction unit 12.

  As described above, the setting timing of the time T to the timer unit 11 is as follows: (1) the side brake is changed from the on state to the released state, and (2) the main switch 2 is changed from off to on. The timing of the later one of the two coincides with the timing realized later.

  Following step 120, the dangerous state prediction unit 12 determines whether or not a predetermined time T has elapsed from the start of the travel standby state depending on whether or not a timer expiration signal has been received from the timer unit 11 in step 130 (the timer is This determination is repeated until it is determined that it has elapsed.

  However, during the repetition, step 140 is executed to determine whether or not the vehicle speed exceeds a threshold value Vt (for example, 3 km / h) based on the detection signal from the vehicle speed sensor 5, and the threshold value Vt must be exceeded. For example, the process returns to step 130 as it is, and if the threshold value Vt is exceeded, the process returns to the determination of whether or not the vehicle in step 110 is in the travel standby state. This is because when the vehicle has already started traveling, it is no longer necessary to notify the traveling standby state because it is no longer in the traveling standby state.

  If it is determined in step 130 that the time T has elapsed, then in step 150, the warning signal to the warning control unit 13 is turned on from off. As a result, the warning control unit 13 notifies the driver that the vehicle is in the travel standby state by using part or all of the seat vibration unit 6, the sound generation unit 7, and the display unit 8.

  For example, it starts to vibrate only the driver's seat among the vehicle seats. The reason for limiting to the driver's seat only is that it is basically only the driver that needs to notify the vehicle of the traveling standby state. Further, for example, the sound generation unit 7 may be controlled to start repeatedly outputting an announcement sound “the vehicle is in a driving standby state”, to start outputting a chime sound periodically, or to simulate an engine idling sound. You may start to output the sound. Further, for example, the characters “the vehicle is in a travel standby state” may be displayed on the display unit 8. These three examples may be combined as appropriate.

  Subsequent to step 150, the dangerous state prediction unit 12 proceeds to step 160 and waits until the vehicle speed exceeds the threshold value Vt, that is, until the vehicle starts to travel. When the vehicle speed exceeds the threshold value Vt, subsequently, in step 170, the warning signal to the warning control unit 13 is turned off from on, and then the process returns to the determination in step 110 as to whether or not the vehicle is in a standby state.

  When the warning signal from the dangerous state prediction unit 12 is turned off, the warning control unit 13 stops the vibration of the seat vibration unit 6, stops the output of the sound generation unit 7, ends the display of the display unit 8, and the like. Then, the warning notification that the vehicle is in the traveling standby state is terminated.

  Hereinafter, specific operation timings of the travel standby state notification device 1 that performs such processing will be described with reference to FIG. FIG. 3 is a graph in which the horizontal axis represents time t and the vertical axis represents vehicle speed V, and the solid line 21 represents changes in the vehicle speed of the vehicle.

  First, it is assumed that the driver gets on the vehicle at time t0, and the main switch 2 is turned on at time t1 to release the side brake. The vehicle speed during the period from time t1 to time t2 is zero. Therefore, the dangerous state prediction unit 12 determines that the vehicle is in the travel standby state at step 110 at time t1, and then sets time T in the timer unit 11 at step 120.

  Thereafter, it is assumed that the time T elapses without the driver performing an accelerator operation for reasons such as waiting for another passenger. Then, at the time t2 = t1 + T, the dangerous state prediction unit 12 determines that the timer has expired in step 130, and further switches on the warning signal in step 150. Thereby, the warning control part 13 performs the warning notification which notifies a driving | running | working standby state.

  Thus, before the vehicle starts, the warning control unit 13 gives a warning notification when the driver forgets the driving standby state after a while from the driving standby state, so that the driver receives the warning notification at an appropriate timing. This reduces the possibility of accidental accelerator operations.

  Then, after the time t2, when the driver intentionally performs the accelerator operation, the vehicle starts running and accelerates, and the vehicle speed reaches the threshold value Vt. Then, at the time point t3 immediately after that, the dangerous state prediction unit 12 determines in step 160 that the vehicle speed has exceeded the threshold value Vt, proceeds to step 170, and switches off the warning signal. Then, the warning control part 13 complete | finishes the warning notification that it is the driving | running | working standby state which became unnecessary.

  Thereafter, it is assumed that the vehicle decelerates and is temporarily stopped at time t4 for the purpose of waiting for a signal or the like. In this case, since the main switch 2 remains on and the side brake remains in the released state, it is immediately determined in step 110 that the vehicle is in the travel standby state, and the time T is set in the timer unit 11 in step 120.

  Thereafter, it is assumed that the time T has elapsed without the driver performing an accelerator operation. Then, at the time t5 = t4 + T, the dangerous state prediction unit 12 determines that the timer has expired in step 130, and further switches on the warning signal in step 150. Thereby, the warning control part 13 performs the warning notification which notifies a driving | running | working standby state.

  As described above, even when the vehicle is temporarily stopped, the warning control unit 13 gives a warning notification when the driver forgets the driving standby state after a while from the driving standby state. , Thereby reducing the possibility of accidental accelerator operation.

  Then, after the time t5, when the driver intentionally performs an accelerator operation, the vehicle starts running and accelerates, and the vehicle speed reaches the threshold value Vt. Then, at time t6 immediately after that, the dangerous state prediction unit 12 determines in step 160 that the vehicle speed has exceeded the threshold value Vt, proceeds to step 170, and switches off the warning signal. Then, the warning control part 13 complete | finishes the warning notification that it is the driving | running | working standby state which became unnecessary.

  As described above, the travel standby state notification device 1 determines whether or not the vehicle is in a travel standby state in which the vehicle starts to move when the driver of the vehicle performs an accelerator operation (step 110), and determines that the vehicle is in the travel standby state. When the predetermined time has elapsed since the start of the travel standby state, it is determined whether or not the driver is in a dangerous state not aware of the travel standby state (step 130). Based on the determination, the driver is notified that the vehicle is in a travel standby state (steps 150 to 170, warning control unit 13).

  By doing so, the possibility that the driver is wastefully notified that the vehicle is in the travel standby state is reduced even in a situation where the driver travel standby state is conscious. Therefore, it is possible to make the driver notice that the vehicle is in the traveling standby state more effectively than before.

  In other words, a warning is issued even when the driver recognizes that the vehicle is in a standby state or when the side brake is on (not necessarily dangerous), resulting in discomfort to the passengers including the driver. The possibility of being lost can be reduced. Moreover, when the notification that the vehicle is in the travel standby state is given by sound, the possibility that the quietness in the travel standby state, which is an advantage of the electric vehicle, is unnecessarily impaired is reduced.

  In addition, when notifying the vehicle in a running standby state only by vibrating only the vibration portion attached to the driver's seat of the vehicle, the driver is given a stimulus similar to that generated when idling a vehicle having an internal combustion engine. The driver can empirically recognize that the vehicle is in a stand-by state, and therefore forgets that the vehicle is in a stand-by state despite being notified. The possibility of performing the operation is reduced. In addition, it is possible to inform the driver of the dangerous state without causing discomfort to passengers who are not related to driving.

  Further, the travel standby state notification device 1 ends the notification that the vehicle is in the travel standby state based on the fact that the vehicle speed of the vehicle has exceeded a predetermined threshold. By doing so, it is possible to enable comfortable and quiet driving by stopping the warning and stopping the useless warning notification to the driver when it can be estimated that the vehicle has left the standby state and has entered the driving state.

  In the above-described embodiment, the travel standby state notification device 1 corresponds to an example of the travel standby state determination unit by executing the process of step 110 of the dangerous state prediction unit 12, and dangerous by executing the process of step 130. It corresponds to an example of a state determination unit, and corresponds to an example of a notification unit by executing the processing of steps 150 to 170 and the processing of the warning control unit 13.

(Other embodiments)
As mentioned above, although embodiment of this invention was described, the scope of the present invention is not limited only to the said embodiment, The various form which can implement | achieve the function of each invention specific matter of this invention is included. It is. For example, the following forms are also acceptable.

  (1) In the embodiment described above, when the seat vibration unit 6 is vibrated in order to notify the traveling standby state, it may be always vibrated with the same strength (amplitude) during the vibrating period. The strength may be gradually increased or decreased to reduce the possibility of surprise or incongruity of the driver. Specifically, the strength may be increased stepwise from zero to a maximum value at the start of vibration, and the strength may be decreased stepwise from the maximum value to zero at the end of vibration.

  (2) In the above embodiment, the time T set in the timer unit 11 is a constant value. However, the time T may be changed according to the situation. For example, in the case where the dangerous state prediction unit 12 has traveled since the last turn-on of the main switch 2 in step 120, rather than the case where the vehicle has not traveled since the last time the main switch 2 was turned on. However, a long time may be adopted as the set time T. As for whether the vehicle has not yet traveled since the main switch 2 was last turned on or whether the vehicle has traveled since the last time the main switch 2 was turned on, the vehicle speed history since the last time the main switch 2 was turned on is stored. What is necessary is just to determine using what was done.

  The travel standby state in the case where the vehicle is not traveling since the last turn-on of the main switch occurs in a time period from when the driver gets on the vehicle until the start of travel. The travel standby state when the vehicle has been played since the last turn-on of the main switch occurs when the vehicle is temporarily stopped, such as waiting for a signal. When comparing the former with the latter, the latter tends to be more tensioned by the driver, so the time until the vehicle forgets that the vehicle is in the travel standby state often becomes longer.

  Therefore, as described above, the predetermined time is longer when the vehicle has traveled since the last time the main switch 2 was turned on than when the vehicle has not traveled since the last time the main switch 2 was turned on. By doing so, it is possible to further reduce the possibility that the travel standby state is notified unnecessarily.

  From the same point of view, even when the vehicle is parked, the time T set in step 120 may be a longer time than when the vehicle has not yet traveled since the main switch 2 was last turned on. . This is because when the vehicle is parked, the driver should be strongly aware that the vehicle is in a traveling standby state. Whether or not the vehicle is parked may be determined based on, for example, whether or not the vehicle shift position is the reverse position.

  (3) Further, in step 130 of the above embodiment, whether or not the driver is in a dangerous state not aware of the travel standby state, whether or not a predetermined time T has elapsed since the start of the travel standby state. Although it is determined based on this, it does not necessarily have to be this way.

  For example, in step 130, it may be determined whether or not the vehicle is in a dangerous state based on the detection result of a sensor that detects the driver's action.

  For example, based on the detection signal of the brake pedal sensor 4, it is determined whether or not the driver is depressing the brake pedal. If the driver is depressing, it is determined that the driver is not in a dangerous state. May be. This is because when the driver is stepping on the brake pedal, the driver is highly likely to be aware that the vehicle is in the travel standby state.

  Further, for example, when a camera (not shown) that captures the driver's face is mounted in the vehicle interior, in step 130, the driver's line-of-sight direction using a known image recognition technique based on the image of the camera's imaging result. If the state in which the detected line-of-sight direction is out of the predetermined range ahead of the vehicle continues for a reference time (for example, 5 seconds shorter than the above time T) or more, it is determined to be a dangerous state. It may be determined that it is not in a dangerous state. This is because if the driver is looking away continuously, there is a high possibility that the driver has forgotten that the vehicle is in a traveling standby state.

  Further, for example, when a camera (not shown) that captures the driver's head is mounted in the passenger compartment, in step 130, the driver's face is detected by a well-known image recognition technique based on the image of the camera. If the state in which the detected face orientation deviates from the predetermined range ahead of the vehicle continues for a reference time (for example, 5 seconds shorter than the above time T) or more, it is determined to be a dangerous state, Otherwise, it may be determined that it is not in a dangerous state. This is because if the driver is looking away continuously, there is a high possibility that the driver has forgotten that the vehicle is in a traveling standby state.

  Further, for example, it is determined whether or not the driver is holding the steering wheel based on a detection signal from a contact sensor (not shown) provided on the steering wheel of the vehicle. If it is not gripped, it may be determined that it is in a dangerous state. This is because the fact that the driver is holding the steering wheel means that he intends to drive, so the accelerator operation in such a case is intended for the driver to drive the vehicle. This is because there is a high possibility.

  Also, for example, based on a plurality of contact detection type seating sensors (not shown) provided at a plurality of positions on the seating portion of the driver's seat (portions where the buttocks and thighs are in contact), the driver is seated in the driver's seat in the correct posture If it is grasped, it is determined that it is not in a dangerous state, and a state where it is not seated in a correct posture continues for a reference time (for example, 5 seconds shorter than the above time T). For example, it may be determined that it is in a dangerous state, and if not, it may be determined that it is not in a dangerous state. This is because, when the driver is continuously losing his / her posture, there is a high possibility that he / she has forgotten to be in the travel standby state.

  It should be noted that these listed methods may be appropriately combined to determine whether or not there is a dangerous state.

  (4) When a vehicle equipped with the travel standby state notification device 1 such as a vehicle equipped with an automatic transmission can select a parking range as a drive range, a drive range sensor (not shown) ) To determine whether or not the parking range is selected, and the standby condition is “the main switch 2 is on, the vehicle is stopped, and the side brake is in the released state” And the parking range is not selected ”may be adopted.

  (5) Moreover, in the said embodiment, although the electric vehicle is illustrated as a vehicle which mounts the driving | running | working standby state notification apparatus 1, the driving | running | working standby state notification apparatus 1 is effective even if it mounts in vehicles other than an electric vehicle. There are cases. For example, even if the vehicle is driven by engine power, if the vehicle is an idling stop vehicle having an idling stop function that stops the rotation of the engine when the vehicle is stopped, the driver forgets the driving standby state, similar to an electric vehicle. There is a possibility. Therefore, even if the running standby state notifying device 1 is mounted on the idling stop vehicle, the same effect as described above can be obtained.

  (6) Moreover, in said embodiment, each function implement | achieved when CPU of the driving | running | working standby state notification apparatus 1 runs a program is the hardware (For example, a circuit structure can be programmed) which has those functions. It may be realized using a possible FPGA).
