  The present invention relates to an electronic device or the like that notifies information when an engine is turned off.

  Patent Document 1 discloses a vehicle control device that is attached to an automobile equipped with a turbocharged engine. After the engine switch is turned off, the vehicle is idled for idling time, and the display means displays the idling time during the idling time. The idea of displaying the remaining time is disclosed.

Japanese Patent No. 3274816

  In this way, even after the engine switch is turned off, a control device that is supplied with power for after-idling can display even after the engine switch is turned off.

  However, for example, in an aftermarket (retrofit) device that receives power supply from a cigar socket of a vehicle, the power supply is cut off together with the engine off, so that information cannot be displayed after the engine is turned off. was there.

  Further, Patent Document 1 discloses the idea of calculating the remaining time of after-idling based on the travel history, but the only display is the current value counted down from the after-idling time determined based on the travel history. It was the remaining time of after idling. Therefore, it was impossible to know what kind of driving was done.

  Further, since the remaining time of the current after idling is simply displayed, there is a problem that it is not clear whether the time is longer or shorter than that based on the past travel history.

  Accordingly, the present invention has been made to solve such problems and the like, and provides an electronic device that can display a traveling result in an easier-to-understand manner than ever in an electronic device that notifies information when the engine is off. The purpose is to do.

  (1) In order to achieve the above-described object, an electronic device according to the present invention is an electronic device that is configured to be fixed to a vehicle and operates based on supply of power from the vehicle. Whether the vehicle is ready to run, or the vehicle is ready to run, and continues to operate during the runnable state, and the vehicle is switched from the runnable state to the non-runnable state. Control means for continuing the operation for a predetermined time from the time point and stopping the operation after the predetermined time has elapsed, and the control means provides a notification content at the end of the predetermined travel when the vehicle is switched from the travelable state to the non-travelable state. It is characterized by performing control for notifying of the above.

  The structure that can be fixed to the vehicle may be, for example, a structure provided with means for directly fixing to the vehicle, or indirectly fixed to the vehicle such as a structure having means for fixing to the vehicle fixing means (for example, a bracket). The structure provided with the means to do may be sufficient. The fixed place is preferably in the passenger compartment, and is preferably a position that can be visually recognized by the driver. For example, it is good to set it as the structure fixed with respect to a dashboard or a windshield. As a structure to fix, you may make it stick with an adhesive agent, a double-sided tape etc., for example, and you may make it adsorb | suck and fix with a suction cup etc.

  For example, the state in which the vehicle is traveling or the state in which the vehicle can travel means that energy can be supplied to a power source for traveling the vehicle, for example, the main power is This indicates that the vehicle is in an on state and the like, and indicates a state where the vehicle can be driven or a state where the vehicle is traveling according to an instruction from the driver. The boundary between the runnable state and the non-runnable state can be arbitrarily determined. For example, the travelable state may be a state in which the vehicle starts to travel when the driver sets the gear to the drive mode, releases the brake, and steps on the accelerator. For example, as shown in (12), when the vehicle is configured to travel by an engine (internal combustion engine), the travelable state is between the time the engine is started and the time it is stopped based on the driver's instruction. For example, when the vehicle is an electric vehicle, it may be in a state where power is supplied to the motor control device in accordance with an instruction from the driver.

  The acquisition of whether or not the vehicle is in a travelable state may be performed, for example, by acquiring a signal from the vehicle, or may be provided with a sensor in the electronic device, acquired by the sensor, and based on the state May be performed. As a configuration for acquiring a signal from a vehicle, for example, a configuration for acquiring from a switch (for example, a key switch or a push switch) for turning on / off the main power of the vehicle may be used. For example, supply of power from the vehicle It is good also as a structure acquired based on this state. Moreover, it is good also as a structure acquired from the signal of in-vehicle LAN. As a configuration to be acquired by a sensor, for example, it may be acquired by detecting the presence or absence of predetermined vehicle vibration. The acquisition of whether or not the vehicle is ready to travel is preferably acquisition of a reliable state, but may be acquisition of an estimated state.

  The predetermined time may be a predetermined time, or may not be a predetermined time until a predetermined state is reached until a predetermined process is completed.

  For example, the notification may be performed by display or sound. That is, as the notification means, a display means, a sound output means, or the like can be used. The notification means may be a component of the electronic device, or may be a general-purpose device (for example, a mobile phone having a monitor, a speaker, or the like) without being a component of the electronic device. For example, the content displayed together with the display may be controlled to be read out and output as speech by speech synthesis.

  (2) The notification content at the time of completion of traveling may be content based on at least one of the state of the vehicle or the driver acquired while continuing the operation for the predetermined time.

As the state of the vehicle acquired while continuing the operation for the predetermined time, for example, the state of the remaining fuel of the vehicle may be set. And as the notification content at the time of the completion | finish of driving | running | working based on this state, you may make it alert | report the acquired information itself, and you may make it alert | report the information produced | generated from the acquired information. For example, when the state of the remaining fuel of the vehicle is acquired as the state of the vehicle, the acquired remaining fuel itself may be notified, or a cruising distance display obtained from the remaining fuel may be notified. Good.
The driver's state acquired while continuing the operation for the predetermined time may be biometric information such as the driver's heart rate.

  (3) The control means acquires at least one state of the vehicle or the driver during the travelable state, and the notification content at the end of travel is the vehicle or the drive acquired during the travelable state. The content may be based on the state of at least one of the persons.

In particular, as a vehicle state acquired during the travelable state, for example, as shown in (4), it is preferable to have at least one of fuel consumption, travel time, travel distance, and fuel consumption.
The above (2) and (3) are more preferably performed together.

  (4) The vehicle state acquired during the travelable state may have at least one of fuel consumption, travel time, travel distance, and fuel consumption.

  (5) At least one state of the vehicle or the driver during the travelable state may be acquired a plurality of times, and the notification content at the end of travel may be generated based on the acquired state a plurality of times. .

  For example, as the state of a plurality of vehicles, three-axis acceleration of the front, rear, left, right, top and bottom of the vehicle is acquired at a predetermined interval such as 10 ms, and information on whether or not eco-driving is performed is generated based on the acceleration state It is advisable to notify them.

  (6) The control means is configured to perform a control for notifying the content based on the state together with the content based on the state as the notification content at the time of the end of traveling together with a comparative notification content that is a notification content to be compared. It is good to do.

  The comparison notification content is, for example, stored in accordance with the type of notification content, and the general content is notified together with the notification content, so that the difference between the notification content and the general state can be determined by the user. Can be grasped. For example, by notifying the general fuel consumption stored as the comparison notification content and notifying the actual fuel consumption as the notification content, the driver compares the actual fuel consumption of the current traveling with the general fuel consumption. Therefore, I can reflect on this driving method.

  (7) The control means stores information on the state or information on the content based on the state until the operation is stopped, and stores the information on the comparison notification when the next operation is performed. It is preferable to use a configuration using information based on the information.

  In this way, information based on information related to the previously notified notification content is used as the comparative notification content when the next operation is performed. For example, the notification content in the previous travel unit and the notification content in the current travel unit are used. Can be compared. In particular, as shown in (8), the notification content and the comparison notification content may be configured for each predetermined counting unit. For example, the time zone is used as the predetermined counting unit, and the notification content such as the average fuel consumption, fuel consumption, average speed, etc. in the off time zone is used as the notification content. The notification content may be displayed at the same time as the day before yesterday. Moreover, it is good to perform the total for every day of the week as a predetermined total unit, and to notify the fuel consumption change by the day of the week. For example, when used for commuting, a report may be made to compare the effect of changes in time zone, day of the week, weather, temperature, season, etc. on fuel consumption in units of one week or one month.

  In this way, the notification content and the comparison notification content can be compared for each predetermined counting unit. For example, according to the configuration of the specific example described above, it is possible to grasp the mileage at the time of commuting, returning home, and the traffic jam situation.

  In addition, incidental information such as weather, temperature, and round trip time may be notified together with the notification contents. In this way, it is possible to make comparisons that include incidental information. Moreover, it is good to comprise so that the kind of comparison alerting | reporting content and a predetermined total unit can be set from a user. For example, a setting screen may be displayed, and the date, day of the week, time, etc. may be arbitrarily set from the setting screen, and displayed when it is off. For example, the display items may be sent in order by the operation so that the operation can be performed for a certain period of time using a remote controller, a touch panel, or the like when the device is off.

As the notification content and the comparison notification content, for example, in addition to the average fuel consumption, the fuel consumption amount, and the average speed, it is preferable to display a travel distance, a maximum speed, the number of eco-driving dangerous driving times, an average engine load factor, and the like.
(8) The content based on the state and the comparison notification content may be configured for each predetermined counting unit.

  (9) Further, for example, a position information storage unit that stores a position of a predetermined point and a current position acquisition unit that acquires a current position of the vehicle are provided, and the control unit is acquired by the current position acquisition unit. A configuration for storing the state of the vehicle or the state of the driver when the current position is in a predetermined approach relationship with the position of the point stored in the position information storage unit, and for generating the notification content; Good.

  For example, as a predetermined point, for example, the vehicle speed measuring device (Obis (registered trademark)) and the vehicle store the vehicle speed when the vehicle approaches a predetermined distance of, for example, 500 m as the vehicle state. As the notification content, the speed may be notified as the speed when passing through the vehicle speed measuring device.

  (10) A configuration in which information about a time until the operation is stopped is notified at a predetermined time interval while the operation is continued for a predetermined time after the vehicle is switched from the travelable state to the non-travelable state. Good.

  Some people are worried that the electronic device will not turn off when the electronic device is turned on because the electronic device still operates after turning off, such as when the engine is turned off. Therefore, it is preferable to add a function to count down the time until the operation is stopped from the off time until the operation is stopped with a number or a bar graph.

  (11) At least the control means continues to operate for a predetermined time after the vehicle is switched from the runnable state to the non-runnable state, and holds the power supply of the electronic device until the operation is stopped after the predetermined time has elapsed. The power supply holding means is preferably provided.

  In this way, even when the vehicle is switched from the runnable state to the non-runnable state, the operation can be continued even with an electronic device in which the power supply from the vehicle is cut off.

  The acquisition timing of the state of at least one of the vehicle and the driver acquired during the travelable state is, for example, a certain time or when a predetermined event occurs, such as when a predetermined state change occurs. May be. In addition, the acquired information may be stored, and the notification content may be generated based on the stored information.

  (12) The vehicle may be configured to travel by an engine, and the travelable state may be a state from when the engine is started to when it is stopped based on a driver's instruction.

  (13) It is good to comprise as a program for making a computer implement | achieve the function as a control means in the electronic device in any one of (1)-(12).

  ADVANTAGE OF THE INVENTION According to this invention, in the electronic device which alert | reports information at the time of an engine off etc., the electronic device etc. which can display a driving | running | working result more easily than before can be provided.

  1 and 2 show the configuration of a radar detector that is a preferred embodiment as an electronic apparatus of the present invention. The radar detector is usually mounted on the dashboard. This radar detector is usually fixed by sticking the bottom surface of the plate 33b of the pedestal 33 on the dashboard. A ball joint receiving portion 33a is provided on the upper portion of the pedestal 33, and the ball portion provided at the lower end portion of the column portion 31 extending downward from the bottom surface of the case body 1 is inserted into the ball joint receiving portion 33a, and the ball portion is inserted. It can be held at an arbitrary angle and posture within the movable range. The pedestal 33 is provided with a spherical concave portion at a predetermined position on the upper surface thereof, and the pedestal 33 is made of a material that can be elastically deformed such as rubber and has an appropriate friction coefficient. The outer diameter of the ball portion and the inner diameter of the recess are set to be approximately equal. As a result, in a state where the ball portion has entered the recess, the outer shape of the ball portion and the inner shape of the recess substantially coincide, and the ball portion can rotate and move in any direction along the spherical surface. And while making both diameters substantially correspond and giving an appropriate friction coefficient to the inner shape of the recess, the ball part can be held at an arbitrary angle and posture. Further, since the pedestal 33 can be elastically deformed, when the case body 1 is urged upward while holding the pedestal 33 from the state shown in FIG. 1, the diameter of the opening of the recessed portion increases and the ball portion is recessed. Can be disengaged from. On the other hand, when the pedestal 33 and the ball part are separated, if the ball part is pressed against the opening of the recess and urged to be pushed toward the pedestal 33 in that state, the opening is caused by the elastic deformation of the recess. The part once expands and the ball part is accommodated in the recess. Thereafter, the shape of the recess is restored to the original by the elastic restoring force of the pedestal 33, and the ball portion is prevented from being easily detached from the recess. Further, one surface of an adhesive member such as an adhesive sheet, a double-sided adhesive tape, or a hook-and-loop fastener is attached to the bottom surface of the pedestal 33, and the other surface of the adhesive member is attached to a predetermined position in the vehicle interior such as a dashboard. Thereby, the base 33 is fixed to the predetermined position in the vehicle interior.

This position history is recorded in the NMEA format, for example.
The standby screen display function is a function for displaying the speed, latitude, longitude, and altitude of the host vehicle detected by the GPS receiver 8 on the display unit 5 as shown in FIG.

  As shown in FIG. 3 (b), the radar scope display function is a position where a target within a predetermined range (for example, within a range of about 1 km) from the current position detected by the GPS receiver 8 is stored in the database 19. This is a function of searching based on information and displaying the relative positional relationship between the vehicle position and the position of the target on the display unit 5. In FIG. 3B, “W” on the left side indicates the west, “E” on the right side indicates the east, and “N” on the upper side indicates the north direction, and the horizontal line connecting “W” and “E” and “N” The icon at the intersection of the vertical line extending downward from "" indicates the vehicle position. Icons having characters such as “L”, “RD”, “P”, and “N” indicate the type and position of the target.

  When pressing of a standby switching button provided on the remote controller 17 is detected during execution of the standby screen display function as shown in FIG. 3A, the radar scope display function is switched to as shown in FIG. Further, when pressing of the standby switch button provided on the remote controller 17 is detected during execution of the radar scope display function, processing for switching to the standby screen display function is performed.

  The control unit 18 performs a GPS alarm function, a radar wave alarm function, a radar wave alarm function according to an event that occurs during execution of the standby screen display function or the radar scope display function (hereinafter, these functions are collectively referred to as a standby function). Processing for realizing each function such as a wireless alarm function is executed. The priority of each function is set in the order of radar wave warning function, radio alarm function, and GPS alarm function from the highest.

  The GPS alarm function is a process executed at a predetermined time interval (1 second interval) by an event from a timer included in the control unit 18 and detected by the latitude and longitude of the target stored in the database 19 and the GPS receiver 8. The distance between the current position is obtained from the latitude and longitude of the current position, and when the obtained distance reaches a predetermined approach distance (for example, within 500 m), that fact is displayed on the display unit 5 and an approach warning indicating that fact from the speaker 20. This is a process for outputting the voice.

  Such targets include snoozing driving accident points, radar, speed limit switching points, control areas, inspection areas, parking monitoring areas, N systems, traffic monitoring systems, intersection monitoring points, signal ignorance suppression systems, police stations, frequent accidents Area, frequent on-board areas, sudden / continuous curve (highway), branch / merge point (highway), ETC lane advance guidance (highway), service area (highway), parking area (highway), highway Oasis (highway), smart interchange (highway), PA / SA petrol station (highway), tunnel (highway), highway radio reception area (highway), prefectural border notice, roadside station, viewpoint parking, etc. The type information of these targets, the latitude / longitude information indicating the position thereof, and the display on the display unit 5 The formula diagram or photo data and audio data are stored in the database 19 in association with each other.

  The radar wave warning function is used when the microwave receiver 4 detects a signal corresponding to a microwave in a frequency band emitted from a velocity measuring device (mobile radar or the like (hereinafter simply referred to as “radar”)). This is an alarm function for displaying an alarm screen on the display unit 5 and outputting an alarm sound from the speaker 20. For example, when a microwave in a microwave frequency band emitted by a radar is detected by the microwave receiver 4, as shown in FIG. 4, a schematic diagram or a photograph of the radar stored in the database 19 is displayed on the display unit 5. While being displayed as an alarm screen, the voice data stored in the database 19 is read out and a voice “Radar. Speed attention” is output from the speaker 20. During sound output, the alarm lamp 6 is turned on.

  The wireless alarm function is a function for issuing an alarm so that the wireless receiver 15 does not interfere with traveling or the like when a radio wave emitted by an emergency vehicle or the like is received.

For example, when a control radio is received, a voice is output like “control radio. Speed attention”. During sound output, the alarm lamp 6 is turned on.

  In addition to these functions, the radar detector of the present embodiment has an operation result display function. As shown in FIG. 5, the operation result display function is a function for displaying the current operation result in comparison with the current operation result. The current operation is an operation from when the power supply from the DC jack 21 is started until the power supply from the DC jack 21 is cut off (hereinafter referred to as a current operation section). Moreover, today's driving | operation is driving | operation from 0:00 to 24:00 of today.

  The control unit 18 performs a vehicle travelability detection process for detecting whether there is power supply from the DC jack 21. When the power supply from the DC jack 21 is started, the microcomputer in the control unit 18 is operated, and the CPU in the microcomputer acquires the current time from the real-time clock provided in the control unit 18, and the RAM in the control unit 18. The process which memorize | stores as this operation start time is performed.

  After that, the control unit 18 acquires the vehicle information described above every other second and detects the acquired vehicle information from the real-time clock while it is detected that power is supplied from the DC jack 21 by the vehicle traveling availability detection process. The current time is stored in the database 19 as a vehicle information log. At this time, processing for recording instantaneous fuel consumption is performed in the vehicle information log. This instantaneous fuel consumption recording process records the acquired instantaneous fuel efficiency when the instantaneous fuel consumption can be acquired as vehicle information, and acquires either the intake air amount or the injection opening time when the instantaneous fuel consumption cannot be acquired as vehicle information. This is a process of calculating and recording the instantaneous fuel consumption by a known method using the information of the completed one. This is because what kind of information is output as vehicle information for each vehicle for the instantaneous fuel consumption.

  Then, when it is detected by the vehicle traveling availability detection process that the power supply from the DC jack 21 has been lost, the control unit 18 determines that traveling (driving) of the current driving section has ended, and performs a display process at the end of driving. In the process at the time of the end of operation, from the state where any screen by the standby screen display function, radar scope display function, GPS alarm function, radar wave alarm function, or radio alarm function shown in FIGS. Then, the operation result display function of FIG. At this time, the current time is acquired from the real-time clock provided in the control unit 18 and stored in the RAM in the control unit 18 as the current operation end time.

  As shown in FIG. 5, the display screen at the end of operation is a screen composed of a total of 21 cells (display areas) of 3 columns in the left-right direction and 7 rows in the up-down direction. The leftmost column is the display column for the item name, the middle column is the display column for the current operation result (that is, the operation result in the current operation section), and the rightmost column is the current operation result (that is, today's 0 am It is a display column of the operation result between the hour and 24. The first row including the “current” and “today” cells is a heading row indicating the value at which time. The second line below is an eco-driving point display line, which displays “98 point” as an eco driving point of the current driving result and “95 point” as an eco driving point of today's driving result. The third line is a safe driving point display line, which displays “84 point” as a safe driving point of the current driving result and “62 point” as an eco driving point of today's driving result. The fourth line is an average fuel consumption display line, which displays “10.3 km / l” as the average fuel consumption of the current driving result and “10.8 km / l” as the average fuel consumption of today's driving result. . The fifth line is a display line of the travel distance, which displays “43.2 km” as the travel distance of the current driving result and “75.6 km” as the travel distance of the current driving result. The sixth line (bottom line) is a display line of travel time, and “0:40” (indicating 0 hour and 40 minutes) as the travel time of the current operation result, and “1:25” as the travel time of the current operation result. Is displayed.

  Regarding the current driving result, the range of the vehicle information log to which the time information in the range from the current driving start time to the current driving end time stored in the RAM is specified and the vehicle information log in the specified time range is specified. Ask based. On the other hand, today's driving result is obtained based on the vehicle information log in the specified time range by specifying the range of the vehicle information log to which time information in the range from 0:00 to today's driving end time is given. .

  The eco-driving point is a value obtained by subtracting, from 100, the ratio (percentage) of the time that the speed is 0 and the engine speed is not 0 (that is, the idling time) in each travel section in the vehicle information log in the specified time range. Is displayed. For example, the state of FIG. 5 indicates that 98% of the current driving section is not idling time and 2% is idling time, and 95% of the driving section today is not idling time but 5%. Indicates the idling time. By displaying in this way, it is possible to easily compare the current and today's eco-driving points. In the case of FIG. 5, it can be easily understood that the current eco-driving point is higher (the idling time is shorter) than today's eco-driving point.

  The safe driving point indicates the number of speed changes corresponding to sudden acceleration and sudden deceleration (for example, equivalent to 0.2 G or more) in the vehicle information log in the specified time range, and the change in the vehicle speed in the vehicle information log. Check back later. A value obtained by subtracting from 100 the number of changes in speed corresponding to sudden acceleration and sudden deceleration (e.g., corresponding to 0.2 G or more) is displayed as a safe driving point. For example, the state of FIG. 5 indicates that there are 100-84 = 16 sudden accelerations / decelerations in the current operation section, and there are 100-62 = 28 sudden accelerations / decelerations in the operation period today. It is shown that. By displaying in this way, it is possible to easily compare the current and today's safe driving points. In the case of FIG. 5, it is possible to easily grasp the ratio of the current safe driving point to today's safe driving point.

  The average fuel consumption is obtained by calculating an average value of instantaneous fuel consumption in the vehicle information log for each specified time range. For example, according to the display of FIG. 5, it can be easily grasped that the average fuel consumption in the current driving section is slightly worse (10.8-10.3 = 0.5) than the average today.

  The fuel consumption amount is obtained by subtracting the last remaining fuel amount from the first remaining fuel amount in each specified time range. For example, according to the display of FIG. 5, it is possible to easily grasp the ratio of the remaining fuel in the current operation section to the remaining fuel in the operation section today.

  The travel distance is obtained by determining the distance traveled at the vehicle speed from the vehicle speed and the recording interval (1 second) of the vehicle speed in the vehicle information log in the specified time range, and adding these. For example, according to the display of FIG. 5, it is possible to easily grasp the ratio of the travel distance of the current driving section to the travel distance of the current driving section.

The travel time is obtained by integrating the time in the time range in which recording is continued in the vehicle information log in the specified time range. For example, according to the display of FIG. 5, it is possible to easily grasp the ratio of the traveling time of the current driving section to the traveling time of the current driving section.
With the configuration as described above, the current driving result and the current driving result can be easily grasped at the end of driving.

  Then, after the operation result display in FIG. 5 is performed for 10 seconds, the control unit 18 cuts off the power supply from the battery to each unit in FIG.

  The control unit 18 acquires whether or not the vehicle is in a travelable state depending on whether or not power is supplied from the DC jack 21, and continues to operate during the travelable state, and the vehicle travels from the travelable state. The operation is continued for 10 seconds after being switched to an impossible state, and the operation is stopped after 10 seconds. When the vehicle is switched from the runnable state to the non-runnable state, the control unit 18 performs control for notifying the predetermined content at the end of travel in this way.

  The control unit 18 continues to operate for 10 seconds after the vehicle is switched from the runnable state to the non-runnable state, and holds the power supply of the radar detector until the operation is stopped after 10 seconds. Since the configuration includes the means, the operation can be continued even if the power supply from the DC jack 21 is cut off.

  In this way, it is possible to provide a radar detector that can display a traveling result in a more easily understandable manner than a conventional radar detector that notifies information when the engine is off.

  In the present embodiment, whether or not the vehicle is ready to travel is determined based on whether or not power is supplied to the DC jack 21. For example, for a power source for traveling the vehicle, Thus, it may be detected that the energy can be supplied, for example, that the main power is on. The acquisition of this state may be determined directly based on whether a voltage is generated on the main power line as in this embodiment, or is output when the main power is on. The determination may be made indirectly by acquiring data or the like. Further, it may be detected whether or not the vehicle is ready to run by detecting a driver's instruction (operation). For example, when the vehicle is configured to travel using an engine, the travelable state may be a state between the time when the engine is started and the time when the engine is stopped based on an instruction from the driver. Further, acquisition of whether or not the vehicle is in a travelable state as in the present embodiment may be performed by acquiring a signal from the vehicle. However, the electronic device includes a sensor and is acquired by the sensor. It may be performed based on the state. As a configuration for acquiring a signal from a vehicle, for example, a configuration for acquiring from a switch (for example, a key switch or a push switch) for turning on / off the main power of the vehicle may be used. For example, supply of power from the vehicle It is good also as a structure acquired based on this state. Moreover, it is good also as a structure acquired from the signal of in-vehicle LAN. As a configuration to be acquired by a sensor, for example, it may be acquired by detecting the presence or absence of predetermined vehicle vibration. The acquisition of whether or not the vehicle is ready to travel is preferably acquisition of a reliable state, but may be acquisition of an estimated state.

  The definition of the runnable state can be arbitrarily determined.For example, if the driver sets the gear to the drive mode, releases the brake, and steps on the accelerator, the state where the vehicle starts running is defined as the runnable state. It is good to define. For example, when the vehicle is configured to run by an engine (internal combustion engine), the vehicle is in a state from when the engine is started to stopped based on an instruction from the driver, or when the vehicle is an electric vehicle, for example. For example, it is preferable that power is supplied to the motor control device according to the driver's instruction.

  In this embodiment, the display at the end of traveling is performed for 10 seconds. However, this time is not limited to 10 seconds, and may be any predetermined time. However, it is set as time more than the time when users, such as a driver, can visually recognize a display at the time of the end of driving. The predetermined time may be a predetermined time, or may be a time that is not constant, for example, until a speech synthesis process to be described later is completed.

  In the present embodiment, the notification is performed by screen display on the display unit 5, but it may be performed by sound. For example, the control unit 18 may perform control to output a voice that reads out the display content of FIG. 5 from the speaker 20 by voice synthesis (TTS (Text To Speech)). The portion to be read out in FIG. 5 may be limited to some important items, for example, only items having a large difference between this time and today. Since it takes time to read everything, it is possible to easily recognize the difference by reading only important items.

  Further, in the present embodiment, the screen display is performed with the display contents as shown in FIG. 5, but not limited to this, various display contents and screen configurations can be adopted. FIG. 6 is another configuration example of the operation result display screen by the operation result display function. In the area on the right side, the radar chart of the points of “rapid acceleration”, “rapid deceleration”, “idling time”, and “economic speed” (100 points is the maximum value) is displayed. “Sudden acceleration” indicates a location where the acceleration obtained from the speed change of the vehicle information log exceeds +0.2 G, “Sudden deceleration” indicates a location where the acceleration obtained from the speed change of the vehicle information log exceeds −0.2 G, “idling time” "Is a time when the speed is 0 and the engine speed is not 0, and" economic speed "is obtained by a ratio of time when the vehicle speed is in a range of 60 km / h plus or minus 5 km / h. In addition, the total points are displayed numerically on the lower left side of FIG. 6, and the leaf designs corresponding to the total points are displayed on the upper left side. That is, drawing is performed such that the leaf is most lively at 100 points where the total point is the maximum value, and drawing is performed where the leaf is withered toward the zero point which is the minimum value. Such visual display is desirable because the driving result can be immediately grasped at the end of driving.

  In the present embodiment, the display unit 5 and the speaker 20 are provided in the radar detector. However, the radar detector is not provided in the radar detector. Instead, for example, a general-purpose device (for example, a mobile phone having a monitor, a speaker, or the like). Etc.) may be output.

  In the present embodiment, the content to be displayed in the travel end display process is generated based on the information recorded in the database 19 as the vehicle information log. However, the present invention is not limited to this. For example, at the time when the travel end display process is started. You may make it acquire and display a vehicle state. For example, the remaining fuel state of the vehicle may be acquired and displayed. And as the notification content at the time of the completion | finish of driving | running | working based on the vehicle state acquired at this time, you may make it alert | report the acquired information itself, and you may make it alert | report the information produced | generated from the acquired information. For example, when the state of the remaining fuel of the vehicle is acquired as the state of the vehicle, the acquired remaining fuel itself may be notified, or a cruising distance display obtained from the remaining fuel may be notified. Good.

  Furthermore, the driver's state may be acquired and displayed instead of the vehicle information or together with the vehicle information. The driver's state to be acquired may be biometric information such as the driver's heart rate.

  In the present embodiment, the vehicle state during the travelable state is acquired a plurality of times, and the notification content at the end of travel is generated based on the state acquired a plurality of times, but has been described with reference to FIG. Not limited to examples. For example, as the state of a plurality of vehicles, three-axis acceleration of the front, rear, left, right, top and bottom of the vehicle is acquired at a predetermined interval such as 10 ms, and information on whether or not eco-driving is performed is generated based on the acceleration state You may make it alert | report.

  In the present embodiment, as shown in FIG. 5, the present operation result and today's operation result are comparatively notified. However, the comparative notification content includes, for example, general content according to the type of notification content. You may make it memorize | store and notify this general content with the content of alerting | reporting. In this way, the user can grasp the difference from the general state of the notification content. For example, by notifying the general fuel consumption stored as the comparison notification content and notifying the actual fuel consumption as the notification content, the driver compares the actual fuel consumption of the current traveling with the general fuel consumption. Therefore, I can reflect on this driving method.

  In the present embodiment, the control unit 18 stores the vehicle state until the operation is stopped, and performs comparison notification using information based on the stored information as the comparison notification content at the next operation. Yes. As described above, information based on information related to the previously notified notification content may be used as the comparison notification content at the next operation. For example, the notification content (comparative notification content) in the previous travel unit and the notification content in the current travel unit may be compared and notified.

  The notification content and the comparison notification content may be configured for each predetermined counting unit. For example, using the time zone as a predetermined counting unit, as the notification content, the notification content such as the average fuel consumption, fuel consumption, average speed, etc. at the time of power-off is the same time as yesterday, which is the comparison notification content. You may make it display simultaneously with the content of an alert | report of the same time zone as today and the day before yesterday. Moreover, it is good to perform the total for every day of the week as a predetermined total unit, and to notify the fuel consumption change by the day of the week. For example, when used for commuting, a report may be made to compare the effect of changes in time zone, day of the week, weather, temperature, season, etc. on fuel consumption in units of one week or one month.

  In this way, the notification content and the comparison notification content can be compared for each predetermined counting unit. For example, according to the configuration of the specific example described above, it is possible to grasp the mileage at the time of commuting, returning home, and the traffic jam situation.

  In addition, incidental information such as weather, temperature, and round trip time may be notified together with the notification contents. In this way, it is possible to make comparisons that include incidental information. Moreover, it is good to comprise so that the kind of comparison alerting | reporting content and a predetermined total unit can be set from a user. For example, a setting screen may be displayed, and the date, day of the week, time, etc. may be arbitrarily set from the setting screen, and displayed when it is off. For example, the display items may be sent in order by the operation so that the operation can be performed for a certain period of time using a remote controller, a touch panel, or the like when the device is off.

  As the notification content and the comparative notification content, for example, in addition to the average fuel consumption, fuel consumption, and average speed, it is preferable to display a travel distance, maximum speed, eco-driving degree, number of dangerous driving, average engine load factor, and the like.

  Further, the GPS alarm function obtains the distance between the latitude and longitude of the target stored in the database 19 and the latitude and longitude of the current position detected by the GPS receiver 8, and the obtained distance is a predetermined approach distance (for example, within 500 m). ) Is displayed on the display unit 5, and when outputting an approach warning sound indicating that from the speaker 20, the vehicle state or the driver state is stored, It is good also as a structure used for a production | generation. For example, as a predetermined point, for example, the vehicle speed measuring device (Obis (registered trademark)) and the vehicle store the vehicle speed when the vehicle approaches a predetermined distance of, for example, 500 m as the vehicle state. As the notification contents, the speed may be scroll-displayed sequentially in the blank area on the right side of the uppermost stage in FIG. 5 (above the areas “current” and “today”) as the speed when passing through the vehicle speed measuring device. .

  In addition, the 10-second countdown display described above may be performed in this blank area. In the above-described embodiment, even after the engine is turned off, the radar detector operates for 10 seconds, so some people are worried that the radar detector cannot be turned off while the power is on. Therefore, it is preferable to add a function to count down the time until the operation is stopped for 10 seconds from when the engine is turned off until the operation is stopped with a number or a bar graph.

  The acquisition timing of the state of at least one of the vehicle and the driver acquired during the travelable state is, for example, a certain time or when a predetermined event occurs, such as when a predetermined state change occurs. May be. In addition, the acquired information may be stored, and the notification content may be generated based on the stored information.

  In the present embodiment, power is supplied by connecting to a cigar socket of a vehicle via a cigar plug cord. However, power may be supplied from an ODB connector.

  In this embodiment, the example of the radar detector has been described. However, the present invention can be implemented as a function of various in-vehicle electronic devices. For example, you may incorporate as a function of a navigation apparatus, a drive recorder, and a car audio. In addition, the numerical values described in the present embodiment may be appropriately changed to values that exhibit an effect through experiments and the like. The screen size of the display unit 5 can also be set arbitrarily. Further, the control unit 18 is provided with a function of setting the priority order of each function and alarm based on an instruction from the user from the remote controller 17 or the like, and the control unit 18 performs processing in this set priority order. It may be configured.
