Description

  The present invention relates to vehicle control technology, and more particularly to control related to idling stop.

  There has been proposed an engine control technique for improving fuel efficiency and protecting the environment by automatically stopping the engine when the vehicle is temporarily stopped (idling stop) and restarting the engine when the vehicle restarts. The conditions for restarting the engine during idling stop include conditions based on the driver's operation such as the driver's brake release operation and accelerator operation, and conditions not based on the driver's operation such as battery charging and air conditioner operation. Can be mentioned. When the engine is restarted when the latter condition is satisfied, for example, the engine may already be restarted when the driver temporarily leaves the vehicle and returns during idling stop.

  Patent Document 1 states that if the engine is already restarted when the driver temporarily leaves and returns to the vehicle while idling is stopped, the driver may feel uncomfortable. When the driver tries to leave the vehicle, a technique for restarting the engine or notifying the driver that the engine is idling stopped is disclosed.

JP 2005-307991 A

  Here, during idling stop, the engine may be restarted in the first place, so it is not desirable for the driver to leave the vehicle, and when the driver tries to leave the vehicle during idling stop. It is desirable to alert the driver. As a method of calling attention, restarting the engine as in Patent Document 1 is one of effective methods. However, if the engine is restarted in a state where the driving force of the engine can be transmitted to the drive wheels, the vehicle may jump out, and there is room for improvement in terms of safety.

  An object of the present invention is to alert a driver while ensuring safety when the driver tries to leave the vehicle during idling stop.

  According to the present invention, when the engine is stalled, the engine stall notification operating means for operating a notification device that notifies the driver that the engine has stalled and the automatic transmission that transmits the driving force of the engine to the drive wheels are in a power transmission state. A transmission state determining means for determining whether the engine is in a non-power transmission state, an automatic stop means for automatically stopping the engine when a preset idling stop condition is satisfied, and an idling stop in which the automatic stop means automatically stops the engine A restart means for restarting the engine when a preset restart condition is satisfied, and an absence determination means for determining whether the driver is in the driver's seat or away from the driver's seat; And when the absence determination means determines that the user is away during the idling stop, the transmission state determination means determines that the non-power transmission state is determined. The restart means restarts the engine regardless of the establishment of the restart condition, and when the transmission state determination means determines that the power transmission state is present, the engine stall notification operating means is the notification device. Then, the restarting means does not restart the engine even if the restart condition is satisfied thereafter.

  In the present invention, when the driver tries to leave the vehicle during idling stop, different processing is performed depending on the determination result of the transmission state determination means. That is, when the transmission state determination means determines that the non-power transmission state, the driver is alerted by restarting the engine. In this case, even if the engine is restarted, the driving force is not transmitted to the driving wheels, so safety is also ensured. On the other hand, when the transmission state determination means determines that the power transmission state, the same processing as when the engine is stalled is performed. That is, the driver's attention can be urged by the operation of the notification device. And even if the said restart conditions are satisfied, since the said engine is not restarted, safety is also ensured.

  In the present invention, it further comprises an operating state determining means for determining whether the brake is in an operating state or a non-operating state, and during the idling stop, the leaving determination means determines that the driver is away from the seat, and the transmission state When the determination means determines the power transmission state and the operation state determination means determines the non-operation state, the engine stall notification operation means operates the notification device, and the restart means then Even if the restart condition is satisfied, the engine may not be restarted. Even if it is determined that the person is away from the seat by the above-mentioned seat leaving determination means, the driver may feel uneasy if the same processing as when the engine is stalled is performed even when the seat is not actually left. However, according to this configuration, when the brake is in the non-operating state, by performing the same process as when the engine is stalled, the driver is not disturbed while ensuring safety. Can do.

  Further, in the present invention, the restart condition includes a restart condition based on a driver's operation and a restart condition not based on a driver's operation, and the restarting means includes the idling stop, When the absence determination means determines that the person is away from the seat and the transmission state determination means determines that the power transmission state is present, the engine is restarted even if a restart condition not based on the operation of the driver is satisfied. You may make it not. According to this configuration, even when the brake is in an operating state, safety can be further enhanced by preventing the engine from restarting.

  Further, in the present invention, the restart condition includes a restart condition based on a driver's operation and a restart condition not based on a driver's operation, and the restarting means includes the idling stop, When the absence determination means determines that the driver has left the seat, and the transmission state determination means determines that the power transmission state is present, the engine even if a restart condition not based on the driver's operation is satisfied. And then the engine is restarted after elapse of a predetermined time, and the engine is restarted after elapse of the predetermined time. A restart notification means for notifying the driver of this may be further provided. According to this configuration, it is possible to prevent the engine from being unexpectedly restarted and giving anxiety to the driver who has returned to the seated state while satisfying the restart request of the engine due to the establishment of the restart condition. .

  In the present invention, an alarm unit may be further provided that issues an alarm when the absence determination unit determines that the user is away during the idling stop. According to this configuration, the driver can be alerted.

  As described above, according to the present invention, when the driver tries to leave the vehicle during idling stop, the driver can be alerted while ensuring safety.

<First Embodiment>
FIG. 1 is a block diagram of a vehicle control apparatus A according to an embodiment of the present invention. The vehicle control device A includes an ECU 100 and mainly controls the engine 10. The engine 10 is, for example, a multi-cylinder gasoline engine. The engine 10 includes an air flow sensor 11 that detects an intake air amount, an intake pressure sensor 12 that detects an intake air pressure, a crank angle sensor 13 that detects a rotation angle of a crankshaft, and an intake valve or an exhaust gas in order to calculate an engine speed and the like. A cam angle sensor 14 that detects the rotation angle of the camshaft that drives the valve, and a water temperature sensor 15 that detects the coolant temperature of the engine 10 are provided to detect the temperature of the engine 10, and the detection results of these sensors are provided. Is input to the ECU 100.

  Further, the engine 10 is provided with an electronic throttle valve 16 that adjusts the amount of intake air to each cylinder, a fuel injection valve 17 that injects fuel into each cylinder, and an ignition device 18 that ignites an air-fuel mixture in each cylinder. Is controlled by the ECU 100.

  An automatic transmission 20 is connected to the output shaft of the engine 10. The automatic transmission 20 includes, for example, a torque converter, a transmission mechanism having a planetary gear mechanism, a clutch, and a brake. The automatic transmission 20 transmits the driving force of the engine 10 to the drive wheels 40 via the differential device 30. The automatic transmission 20 is controlled by an AT control device 21. The AT control device 21 includes, for example, a hydraulic control circuit that engages and releases the clutch and brake of the automatic transmission 20.

  The automatic transmission 20 controls the automatic transmission 20 according to the shift position of the shift lever 60 provided at the driver's seat of the vehicle. The shift position of the shift lever 60 is detected by a shift position sensor 61, and the detection result is input to the automatic transmission 20.

  In this embodiment, the shift position of the shift lever 60 is a P range (parking range), an R range (reverse range), an N range (neutral range), and a D range (drive range). When the P range and the N range are selected, the automatic transmission 20 is controlled to a non-power transmission state in which the driving force of the engine 10 is not transmitted to the driving wheels 40.

  When the R range and the D range are selected, the automatic transmission 20 is controlled to a power transmission state in which the driving force of the engine 10 is transmitted to the drive wheels 40, and when the R range is selected, the vehicle is moved backward. When the D range is selected in the direction, the driving force is transmitted in the direction of moving the vehicle forward. When the D range is selected, the AT control device 21 switches the automatic transmission 20 to a gear position according to the vehicle speed or the rotation speed of the engine 10 in accordance with a control command from the ECU 100.

  The shift position of the shift lever 60 is detected by a shift position sensor 61, and the detection result is also input to the ECU 100. In this embodiment, when the detection result of the shift position sensor 61 indicates the P range and the N range, the ECU 100 determines that the automatic transmission 20 is in the non-power transmission state and indicates the D range and the R range. In this case, it is determined that the automatic transmission 20 is in the power transmission state.

  The engine 10 is provided with a starter 50 that uses a battery 52 as a power source, and is controlled by the ECU 100 to be driven when the engine 10 is started. The engine 10 is provided with a generator 51. The generator 51 generates power using the driving force of the engine 10. The ECU 100 outputs a control signal to a regulator circuit provided in the generator 51 to control the amount of power generated by the generator 51. The generator 51 charges the battery 52 and supplies electric power to the vehicle electrical components.

  The current / voltage sensor 53 detects a current / voltage for discharging / charging the battery 52. The detection result of the current / voltage sensor 53 is input to the ECU 100, and the charged amount of the battery 52 is calculated based on the detection result. The air conditioner 54 is supplied with electric power from the battery 52 or the generator 51 and performs air conditioning of the passenger compartment. The ECU 100 controls the air conditioner 54 based on the detection result of the temperature sensor 55 when automatic air conditioning is selected by the occupant.

  The IG (ignition) switch 62 detects the start operation of the engine 10 by the driver, and the detection result is input to the ECU 100. The accelerator opening sensor 64 detects a driver's operation amount with respect to the accelerator pedal 63, and the brake pedal sensor 66 detects the presence / absence of the driver's operation with respect to the brake pedal 65. The detection results of these sensors are input to the ECU 100. In the case of the present embodiment, the ECU 100 determines that the brake (not shown) is in an operating state when an operation on the brake pedal 65 is detected, and determines that the brake is in an inoperative state when an operation is not detected.

  The door sensor 67 detects whether the door adjacent to the driver's seat is open or closed. The detection result is input to the ECU 100. In the present embodiment, the ECU 100 determines that the driver is away from the driver's seat when the door sensor 67 detects that the door is open, and if the door is detected to be closed, the driver is present in the driver's seat. Determined to be in the seat. Note that the driver's seating and seating may be determined by, for example, a weight detection sensor provided in the seat of the driver's seat and the detection result, and the seat belt of the driver's seat is engaged / released from the buckle. A sensor for detecting whether or not the detection is performed may be provided, and the determination may be made based on the detection result.

  The vehicle speed sensor 68 detects the traveling speed of the vehicle. The detection result is input to the ECU 100. The speaker 69 is controlled by the ECU 100 to output an alarm sound, various voice guidance, and the like to the driver. The instrument panel 70 is disposed in front of the driver's seat and includes various warning lights 71. In the case of the present embodiment, the ECU 100 turns on all the warning lights 71 simultaneously when the engine 10 is stalled to notify the driver that the engine has stalled. Therefore, in this embodiment, the warning lamp 71 functions as a notification device that notifies the driver that the engine has stalled.

  The ECU 100 includes a CPU 101, a ROM 102, a RAM 103, and an I / F (interface) 104, which are connected by a bus. The CPU 101 executes a control program stored in the ROM 102 to control the engine 10 and the like. In addition to the program executed by the CPU 101, the ROM 102 stores various information necessary for executing the control program. The RAM 103 stores temporary data. The ROM 102 and RAM 103 may be other storage means. The I / F 104 has an input port and an output port connected to the external device of the ECU 100 described above, and the CPU 101 transmits and receives signals to and from the external device via the I / F 104.

  Next, an example of processing executed by the CPU 101 will be described with reference to FIG. Here, processing related to starting and stopping of the engine 10 will be described. The CPU 101 repeatedly executes the process described in FIG. In S1, it is determined whether or not the engine 10 is being driven. If it is driven, the process proceeds to S2. If it is stopped, the process proceeds to S6.

  In S2, it is determined whether or not the detection result of the IG switch 62 has changed from ON to OFF. When it corresponds, it progresses to S3, the fuel injection from the fuel injection valve 17 is cut, and the drive of the engine 10 is stopped. In S4, the engine stall process is executed. Here, processing related to engine stall is performed. FIG. 3A is a flowchart showing the stall process of S4.

  In S11, the detection result of the crank angle sensor 13 is acquired, and it is determined whether or not the rotational speed of the engine 10 is less than a predetermined threshold (for example, 300 rpm). If applicable, the process proceeds to S12. If not applicable, one unit of stall processing is terminated. In S12, the fuel injection from the fuel injection valve 17 is cut and the driving of the engine 10 is stopped. In S13, an engine stall notification process is performed. Here, the driver is notified that the engine has stalled by operating all the warning lamps 71 to light them all. Thus, one unit of stall processing is completed.

  Returning to FIG. 2, in S5, an automatic stop process for automatically stopping the engine 10 is executed when a predetermined idling stop condition is satisfied. FIG. 3B is a flowchart showing the automatic stop process of S5. In S21, it is determined whether or not an idling stop condition is satisfied. If applicable, the process proceeds to S22. If not, one unit of automatic stop processing is terminated.

  The idling stop condition is, for example, that the vehicle speed is 0 and an operation on the brake pedal 65 is detected. Further, depending on the restarting method of the engine 10, requirements necessary for restarting (for example, the water temperature is equal to or higher than a predetermined temperature) can be set as a condition.

  In S22, the fuel injection from the fuel injection valve 17 is cut and the driving of the engine 10 is stopped. In S23, the idling stop flag is turned ON. The idling stop flag is a flag for identifying whether or not the engine 10 is idling stopped, and stores ON / OFF of the flag using a predetermined storage area of the RAM 103. Thus, one unit of automatic stop processing is completed.

  Returning to FIG. 2, in S6, it is determined whether or not the detection result of the IG switch 62 has changed from OFF to ON. If applicable, the process proceeds to S7, where the starter 50 is driven and the engine 10 is started. In S8, it is determined whether or not idling is stopped. When the idling stop flag is ON, it is determined that idling is being stopped, and when it is OFF, it is determined that idling is not being stopped. If it is determined that idling is stopped, the process proceeds to S9, and if not, the process returns to S1.

  In S9, processing related to restart of the engine 10 during idling stop is executed. FIG. 4 is a flowchart showing the restart related process in S9. In S31, an absence determination process for determining whether the driver is present or absent from the driver's seat is executed. In the present embodiment, as described above, whether the driver is present or away is based on the detection result of the door sensor 67. Therefore, in S31, the detection result of the door sensor 67 is acquired, and when the opening of the door is detected, it is determined that the user is away from the seat, and when the door is closed, it is determined that the user is present.

  In S32, if the determination result of S31 is away, the process proceeds to S36, and if present, the process proceeds to S33. In S33, it is determined whether a preset restart condition is satisfied. If applicable, the process proceeds to S34, and if not applicable, one unit of restart-related processing is terminated. The restart condition includes, for example, a restart condition based on the driver's operation and a restart condition not based on the driver's operation. The restart condition based on the driver's operation includes, for example, that the operation on the brake pedal 65 is not detected and the operation on the accelerator pedal 63 is detected. In addition, restart conditions that are not based on the driver's operation include those required for control of vehicle components (hereinafter referred to as vehicle request conditions). For example, the amount of power stored in the battery 52 is small, and the generator 51 There is a case where it is necessary to charge by the power generation, or a case where it is necessary to supplement the power by the power generation of the generator 51 in accordance with the operation of the air conditioner 54.

  In S34, the engine 10 in the idling stop is restarted. Examples of how to restart the engine 10 include a starter drive system that starts with the starter 50, a combustion restart system, or a system that uses the starter 50 in combination with a combustion restart system. As the combustion restart method, there are a normal combustion restart method in which the crankshaft of the engine 10 is immediately forward rotated, and a reverse combustion restart method in which the crankshaft is once reversely rotated and then forwardly rotated. Subsequently, the process proceeds to S35, and the idling stop flag is turned OFF. Thereby, the idling stop is canceled. Thereafter, one unit of restart-related processing is terminated.

  In S36, since it is determined that the driver is away from the seat while idling is stopped, an alarm is activated. In the case of this embodiment, the alarm outputs a warning sound from the speaker 69. As a result, the driver can be alerted. Note that the alarm may be displayed with a display device to call attention.

  In S37, a transmission state determination process for determining whether the automatic transmission 20 is in a power transmission state or a non-power transmission state is executed. In the present embodiment, as described above, the determination is made based on the detection result of the shift position sensor 61. Therefore, in S37, the detection result of the shift position sensor 61 is acquired. When the P range and the N range are indicated, it is determined that the power transmission state is not present. When the D range and the R range are indicated, the power transmission state is indicated. Is determined.

  In S38, if the determination result in S37 is the non-power transmission state, the process proceeds to S34 and the engine 10 is restarted. The driver can be alerted by restarting the engine 10. In this case, since the automatic transmission 20 is in a non-power transmission state, the driving force is not transmitted to the drive wheels 40 even when the engine 10 is restarted. Therefore, safety is also ensured. Subsequently, the process proceeds to S35, and the idling stop flag is turned OFF. Moreover, the alarm which act | operated by S36 stops.

  In S38, when the determination result in S37 is the power transmission state, the process proceeds to S39, and the engine stall notification operation process is performed. Here, the same process as the engine stall notification process of S13 described above is performed. In other words, all the warning lights 71 are operated to be fully lit. Subsequently, the process proceeds to S35, and the idling stop flag is turned OFF. Moreover, the alarm which act | operated by S36 stops.

  By the processing of S39 and subsequent S35, the same state as when the engine is stalled is obtained. That is, the driver's attention can be urged by the engine stall notification operation process in S39. Since the idling stop flag is turned OFF in S35, the restart related process is not executed (No in the determination of S8 in FIG. 2), and the engine 10 is restarted even if the restart condition is satisfied. There is no. Even if the automatic transmission 20 is in the power transmission state, the engine 10 remains stopped, so that the vehicle does not jump out and safety is ensured. When starting the engine 10, the driver needs to turn the IG switch 62 off and then on.

  Thus, in the present embodiment, when the driver tries to leave the vehicle during idling stop, the driver can be alerted while ensuring safety.

Second Embodiment
In the first embodiment, when the door is opened during idling stop, it is determined that the user is away from the seat, and the engine 10 is restarted (S34) or the engine stall notification is activated (S39) depending on the position of the shift lever 60. Either of these is done alternatively. However, when idling is stopped, the door is temporarily opened to eliminate the seat belt being caught in the door, or the door is opened to drive out insects that have entered the vehicle. Or when the door is opened when paying the toll at the toll gate on the toll road, etc. is there.

  In such a case, it is considered that the position of the shift lever 60 often remains in the D range for the subsequent start. In this case, there is a concern that the driver may feel uneasy, for example, whether the engine 10 has failed if the same processing as when the engine is stalled. Therefore, in the present embodiment, whether to perform the same processing as when the engine is stalled is determined depending on whether the brake is in an operating state or a non-operating state. FIG. 5 is a flowchart showing another example of the restart related process in S9.

  In S41, the absence determination process is executed. This is the same process as the above-described absence determination process of S31. In S42, if the determination result in S41 indicates that the determination result in S41 is away, the process proceeds to S49. If the determination result is present, the process proceeds to S43. In S43, it is determined whether or not an alarm in S49 described later is in operation. If it is in operation, the process proceeds to S44, the alarm is stopped, and the process proceeds to S45. If not, the process proceeds to S45.

  In S45, it is determined whether or not the restart flag is ON. The restart flag will be described later. If the restart flag is ON, the process proceeds to S57, and if it is OFF, the process proceeds to S46. In S46, it is determined whether or not a restart condition is satisfied. This is the same processing as S33 described above. If applicable, the process proceeds to S47, and if not, one unit of restart-related processing is terminated. In S47, the engine 10 is restarted. This is the same processing as S34 described above. In S48, the idling stop flag is turned OFF. This is the same processing as S35 described above.

  In S49, since it is determined that the driver is away from the seat while idling is stopped, an alarm is activated. This is the same processing as S36 described above. In S50, a transmission state determination process is executed. This is the same processing as S37 described above.

  In S51, if the determination result in S50 is the non-power transmission state, the process proceeds to S47 and the engine 10 is restarted. Similar to the first embodiment, the driver can be alerted by restarting the engine 10. In this case, since the automatic transmission 20 is in a non-power transmission state, the driving force is not transmitted to the drive wheels 40 even when the engine 10 is restarted. Therefore, safety is also ensured. Subsequently, the process proceeds to S48, and the idling stop flag is turned OFF. Moreover, the alarm which act | operated by S49 stops.

  In S51, if the determination result in S50 is the power transmission state, the process proceeds to S53. In the case of the present embodiment, the engine stall notification does not operate immediately even if the determination result is the power transmission state. In S53, an operation state determination process for determining whether the brake is in an activated state or a non-operated state is executed. In the case of the present embodiment, as described above, it is determined based on the detection result of the brake pedal sensor 66 whether the brake is in the activated state or the non-operated state, and when an operation on the brake pedal 65 is detected, the brake is in the activated state. If it is determined that there is an operation and no operation is detected, it is determined that the device is in an inoperative state.

  In S53, if the determination result in S52 is in the operating state, the process proceeds to S55, and if it is in the inoperative state, the process proceeds to S54. In S54, an engine stall notification operation process is executed. This is the same processing as S39 described above. Subsequently, the process proceeds to S48, and the idling stop flag is turned OFF. Moreover, the alarm which act | operated by S49 stops. As a result, as in the first embodiment, the state is the same as when the engine is stalled, and the driver can be alerted while ensuring safety.

  If the determination result in S52 is the operating state, the brake is operating, and therefore, even if the restart condition is satisfied and the engine 10 is restarted, the possibility of the vehicle jumping out is reduced. However, it is desirable to reliably prevent the vehicle from jumping out. On the other hand, when it is determined that the driver is away from the seat, it is considered that the restart condition based on the driver's operation is not satisfied among the restart conditions, and if the restart condition is satisfied, the vehicle This is considered to be a case where the required condition is satisfied. Then, it is desirable that the engine 10 is restarted when the vehicle requirement condition is satisfied.

  Therefore, first, in S55, it is determined whether or not the vehicle requirement condition is satisfied among the restart conditions. If not applicable, one unit of restart-related processing is terminated. In this case, the idling stop is continued. If applicable, the process proceeds to S56, and the restart flag is turned ON. The restart flag is a flag indicating that the vehicle requirement condition is satisfied, and stores ON / OFF of the flag using a predetermined storage area of the RAM 103. Thereafter, one unit of restart-related processing is terminated. In this case, the idling stop is continued. That is, even if the vehicle requirement condition is satisfied, the engine 10 is not restarted while the driver is determined to be away from the seat, so that the vehicle is surely prevented from jumping out and safety is improved.

  Next, processing when the restart flag is ON will be described. After the restart flag is turned ON, it is determined that the driver is present, and when it is determined in S45 described above that the restart flag is ON, the processing of S57 to S59 is executed.

  First, in S57, the restart flag is turned OFF. In S58, a restart notification process for notifying the passenger that the engine 10 is restarted is executed. In the case of the present embodiment, the notification outputs a guidance voice (for example, the engine will be restarted from now on) from the speaker 69. Note that the notification may be displayed by providing a display device. In S59, the timing process is started. Here, the passage of a predetermined time (for example, about 10 seconds) is waited for. Thereafter, the process proceeds to S47 and the engine 10 is restarted.

  That is, it is desirable that the engine 10 is restarted when the vehicle requirement is satisfied, but when the engine 10 is restarted as soon as the driver returns from the away state to the seated state, There is a possibility that the engine 10 may be unexpectedly restarted for the driver and cause anxiety. In this embodiment, after it is determined that the driver is present, the engine 10 is restarted after a predetermined time has elapsed, and the driver is informed that the driver will be restarted. It can prevent giving a feeling.
