Abstract

PROBLEM TO BE SOLVED: To provide a stop control device for a vehicle capable of securing an improvement effect of fuel consumption by automatic stop and capable of avoiding failure accompanying frequent execution of automatic stop and restart by minutely and appropriately determining a travelling state of a vehicle, and by executing the automatic stop during travelling at moderate frequency according to the determination result.SOLUTION: In a stop control device for a vehicle, it is included in a predetermined condition for automatically stopping an internal combustion engine 3 that a vehicle speed VP is equal to or less than an I/S start vehicle speed VPISTP, which is a value greater than 0. By this condition, an improvement effect of fuel consumption can be secured by executing idle stop during travelling. Also, during the execution of the idle stop during travelling, when the internal combustion engine 3 is restarted by the establishment of a restart condition before a vehicle V stops, by prohibiting the next idle stop during travelling (Steps 9 and 10 in Fig.3 and Steps 21, 22 and 24 in Fig 4.), frequent execution of the idle stop during travelling and restart is avoided.

Description

  The present invention relates to a vehicle stop control device that automatically stops an internal combustion engine when a predetermined stop condition is satisfied, and then automatically restarts the internal combustion engine when a predetermined restart condition is satisfied.

  As a conventional stop control device for this type of vehicle, for example, one disclosed in Patent Document 1 is known. In this stop control device, during traveling at a reduced speed where a predetermined stop condition is satisfied, idling stop during traveling is performed in which the internal combustion engine is stopped without waiting for the vehicle to stop. Further, it is determined whether or not the state where the vehicle speed is equal to or higher than a predetermined speed (for example, 40 km / h) continues for a predetermined time (for example, 10 seconds). As a result of the determination, when this vehicle speed condition is not satisfied, idle stop is prohibited, assuming that the vehicle is traveling on a back street or a country road where the stop is repeated, or is traveling in a traffic jam. This avoids complications and discomfort due to frequent execution of idle stop and restart.

JP 2011-202638 A

  In the conventional stop control device described above, a condition that the state where the vehicle speed is equal to or higher than a predetermined speed continues for a predetermined time or longer is roughly set as an execution condition of the idling stop during traveling, and unless this condition is satisfied, Idle stop is prohibited while driving. For this reason, for example, when a low-speed driving state in which the vehicle speed does not reach the predetermined speed continues for a long time, the idle stop is not performed at all during that period, and the idle stop is limited more than necessary, and the fuel consumption due to the idle stop is reduced. The improvement effect may not be obtained.

  The present invention has been made in order to solve such a problem, and by accurately determining the driving state of the vehicle in a fine and appropriate manner and executing automatic stop during driving at an appropriate frequency according to the determination result. An object of the present invention is to provide a vehicle stop control device that can ensure an improvement effect of fuel consumption by automatic stop and avoid problems associated with frequent execution of automatic stop and restart.

  In order to achieve this object, the invention according to claim 1 of the present application executes an automatic stop that automatically stops the internal combustion engine 3 that is a power source of the vehicle V when a predetermined stop condition is satisfied. , A vehicle stop control device for automatically restarting the internal combustion engine 3 when a predetermined restart condition is satisfied, the vehicle speed acquisition means for acquiring the speed VP of the vehicle V (in the embodiment (hereinafter referred to as this section)). The same vehicle speed sensor 22) is provided, and the predetermined stop condition includes that the acquired vehicle speed VP is equal to or lower than a first predetermined vehicle speed (I / S start vehicle speed VPISTP) greater than 0. When the internal combustion engine 3 is restarted due to the establishment of the restart condition before the vehicle V stops with the automatic stop of the engine 3 being executed, the automatic prohibition of the next automatic stop of the internal combustion engine 3 is prohibited. Stop prohibition means (ECU , And further comprising the step 9 and 10 of FIG. 3, the steps 21, 22, 24) of FIG.

  In this vehicle stop control device, when the predetermined stop condition is satisfied, the internal combustion engine is automatically stopped, so-called idle stop is executed, and then, when the predetermined restart condition is satisfied, the internal combustion engine is automatically Is restarted automatically. Further, the predetermined stop condition includes that the acquired vehicle speed is equal to or lower than a first predetermined vehicle speed that is greater than 0. Under this vehicle speed condition, a so-called idle stop during traveling is performed in which the internal combustion engine is automatically stopped before the vehicle stops. As a result, unlike the above-described conventional technology, an automatic stop is reliably executed during a traffic jam or the like, so that the fuel consumption improvement effect by the automatic stop can be ensured.

  Further, according to the present invention, the internal combustion engine is restarted when the restart condition is satisfied before the vehicle stops, that is, during the execution of the idling stop while traveling, in the state where the automatic stop of the internal combustion engine is being executed. If this happens, the next automatic stop of the internal combustion engine is prohibited. As a result, idling stops and restarts are not performed repeatedly during traveling, such as during traffic jams, and related problems, such as vehicle driving complications and discomfort, automatic stopping and restarting, etc. It is possible to avoid the progress of deterioration of the parts to be performed.

  According to a second aspect of the present invention, in the vehicle stop control device according to the first aspect, when the automatic stop of the internal combustion engine 3 is prohibited by the automatic stop prohibiting means, the vehicle speed VP becomes zero. The automatic stop prohibition release means (ECU 2, steps 27 and 30 in FIG. 4) for canceling the automatic stop prohibition state is further provided.

  According to this configuration, the automatic stop prohibition state is canceled when the vehicle speed reaches a value of 0 while the automatic stop of the internal combustion engine is prohibited during traveling of the vehicle. Thereby, the fuel consumption can be further improved by executing the automatic stop when the vehicle is stopped.

  According to a third aspect of the present invention, in the vehicle stop control device according to the first aspect, the vehicle speed VP is larger than the first predetermined vehicle speed in a state where the automatic stop of the internal combustion engine 3 is prohibited by the automatic stop prohibiting means. It further comprises automatic stop prohibition releasing means (ECU 2, steps 28 and 30 in FIG. 4) for canceling the automatic stop prohibition state when the vehicle speed exceeds the second predetermined vehicle speed (precondition vehicle speed VPHREF).

  According to this configuration, when the vehicle speed is equal to or higher than the second predetermined vehicle speed that is higher than the first predetermined vehicle speed while the automatic stop of the internal combustion engine is prohibited while the vehicle is running, the automatic stop prohibition state is canceled. Is done. As a result, when the vehicle is once out of the traffic jam, the automatic stop prohibition state is canceled, and then the automatic stop is executed when the vehicle speed is equal to or lower than the first predetermined vehicle speed. It is possible to increase the frequency of idling stop and further improve fuel efficiency.

  The invention according to claim 4 is an automatic stop prohibition releasing means (ECU2, FIG. 5) for canceling the automatic stop prohibition state when the automatic stop prohibition state of the internal combustion engine 3 by the automatic stop prohibiting means continues for a predetermined time TREF or more. 4 steps 29 and 30).

  According to this configuration, when the state in which the automatic stop of the internal combustion engine is prohibited during the traveling of the vehicle continues for a predetermined time or longer, the prohibited state is released. As a result, when the vehicle speed does not exceed the value 0 or the second predetermined vehicle speed and the traffic jam continues for a long time, it is avoided that the automatic stop is continuously prohibited, thereby executing the idle stop during running. The frequency can be increased and fuel consumption can be further improved.

FIG. 5 is a timing chart showing another operation example obtained by the processing of FIGS. 3 and 4. FIG.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. A vehicle V shown in FIG. 1 is a front-wheel drive type four-wheel vehicle having left and right front wheels W, W and left and right rear wheels (not shown) (hereinafter collectively referred to as “wheels W”). And an automatic transmission 4 for shifting the power of the engine 3.

  The automatic transmission 4 has a torque converter connected to a crankshaft (not shown) of the engine 3 and eight shift positions including “1, 2, 3, D4, D5, N, R, P” can be selected. And a gear mechanism (none of which is shown in the figure) that can be switched to six types of shift stages including 1st to 5th speeds and reverse gears. After the power of the engine 3 is changed by the automatic transmission 4, it is transmitted to the left and right front wheels W and W via the final reduction mechanism 5 and the left and right drive shafts 6 and 6, thereby driving the vehicle V. Is done.

  The engine 3 is automatically stopped (idle stop) when a predetermined stop condition is satisfied, and thereafter, is automatically restarted when a predetermined restart condition is satisfied, so-called idle stop control is performed. Is. This idle stop control is executed by the ECU 2 described later.

  The engine 3 is automatically stopped by stopping fuel injection from the fuel injection valve 9 (see FIG. 2). The engine 3 is restarted by driving the starter motor 8 with electric power supplied from the battery 7 and rotating the crankshaft (cranking) while injecting fuel from the fuel injection valve 9. .

  As shown in FIG. 2, the CRK signal representing the rotational speed of the crankshaft is inputted from the crank angle sensor 21 to the ECU 2, and the VW signal representing the rotational speed of each wheel W is inputted from the wheel speed sensor 22. . The ECU 2 calculates the engine speed (hereinafter referred to as “engine speed”) NE based on the CRK signal, and calculates a vehicle speed VP that is the speed of the vehicle V based on the VW signal.

  Further, the ECU 2 receives from the shift position sensor 24 a detection signal indicating the opening (hereinafter referred to as “accelerator opening”) AP of an accelerator pedal (not shown) of the vehicle V from the accelerator opening sensor 23. The detection signals representing the shift positions SP are respectively input.

  Furthermore, the ECU 2 receives a detection signal representing the voltage VB of the battery 7 (hereinafter referred to as “battery voltage”) VB from the voltage sensor 25. The ECU 2 calculates a remaining charge (hereinafter referred to as “battery remaining amount”) SOC of the battery 7 based on the battery voltage VB and the like.

  Further, the ECU 2 receives a detection signal indicating the on / off state of the ignition switch 31 and a detection signal indicating the on / off state of a brake pedal (not shown) of the vehicle V from the brake switch 32, respectively. Is done.

  The ECU 2 is composed of a microcomputer including a CPU, a RAM, a ROM, an input interface (all not shown), and the like. The ECU 2 determines the operating state of the engine 3 and the vehicle V based on the control program stored in the ROM in accordance with the detection signals of the various sensors 21 to 25 and the switches 31 and 32 described above, and the determination result. Based on the above, idle stop control of the engine 3 is executed.

  In the present embodiment, the ECU 2 corresponds to an automatic stop prohibiting unit and an automatic stop prohibition releasing unit.

  Next, an idle stop control process executed by the ECU 2 will be described. FIG. 3 shows a main flow of the idle stop control process. This process is repeatedly executed at a predetermined cycle (for example, 1 second).

  In this process, first, in step 1 (illustrated as “S1”, the same applies hereinafter) and step 2, it is determined whether or not the restart flag F_RSTRT and the idle stop flag F_ISTP are “1”. If both of these answers are NO and the engine 3 is not restarting or idling, it is determined in steps 3 to 9 whether or not a predetermined stopping condition for executing idling is satisfied.

Specifically, it is determined whether or not the following conditions (a) to (g) are satisfied.
(A) The ignition switch 31 is in an ON state. (B) The vehicle speed VP is equal to or lower than a predetermined I / S start vehicle speed VPISTP. (C) The accelerator opening AP is substantially zero. (D) The shift position SP is Being other than P, R, N (e) Brake switch 32 is in an ON state (f) Remaining battery SOC is not less than a predetermined value SOCISTP (g) Running I / S prohibition flag F_ISTPNG is “1” Not

  If any of these determination results is NO, it is determined that the predetermined stop condition is not satisfied, and the present process is ended without executing the idle stop. On the other hand, if all of the above determinations are YES, it is determined that a predetermined stop condition is satisfied, the idle stop flag F_ISTP is set to “1” (step 10), and this process is terminated. When the idle stop flag F_ISTP is set to “1” in this way, the fuel supply to the engine 3 is stopped and the idle stop is started.

  The I / S (idle stop) start vehicle speed VPISTP in the above condition (b) determines the vehicle speed VP at which the idle stop is started, and is set to a predetermined value (for example, 10 km / h) larger than zero. By this setting, when the vehicle speed VP becomes equal to or lower than the I / S start vehicle speed VPISTP while the vehicle V is traveling, it is assumed that the other conditions described above are satisfied and the idle stop is performed without waiting for the vehicle V to stop. Is executed. Hereinafter, such an idle stop while the vehicle V is traveling is particularly referred to as an “in-travel idle stop”.

  Further, the traveling I / S prohibition flag F_ISTPNG under the above condition (g) is set to “1” when the traveling idle stop is prohibited by the determination process of FIG. 4 described later.

  After the idling stop is started in accordance with the execution of step 10, the answer to step 2 is YES. In this case, in steps 12 and 13, the accelerator opening AP is a predetermined restart start opening. It is determined whether or not it is greater than or equal to APRSTRT and whether or not the brake switch 32 is in an off state. If both of these answers are NO, this process is terminated as it is, and the idle stop is continued.

  On the other hand, when the answer to step 12 is YES and the accelerator pedal is depressed during the idle stop, or when the answer to step 13 is YES and the brake pedal is released during the idle stop, the engine 3 It is determined that the restart condition is satisfied.

  In that case, the idle stop flag F_ISTP is set to “0” (step 14), the idle stop is ended, the restart flag F_RSTRT is set to “1” (step 15), and this process ends. When the restart flag F_RSTRT is set to “1” in this way, the starter motor 8 is driven to restart the engine 3 and cranking of the engine 3 is started.

  After the restart of the engine 3 is started in this way, the answer to step 1 becomes YES. In this case, the process proceeds to step 16 where the engine speed NE is equal to or higher than a predetermined idle speed NEIDL. Determine whether or not. If the answer is NO and NE <NEIDL, the process is terminated as it is and the cranking is continued.

  On the other hand, if the answer to step 16 is YES and the engine speed NE rises to the idling speed NEIDL or higher due to cranking, the restart flag F_RSTRT is set to “0”, assuming that the restart is completed (step 17). ), This process is terminated.

  Next, the traveling I / S prohibition determination process for setting the above-described traveling I / S prohibition flag F_ISTPNG will be described with reference to FIG. This process is also repeatedly executed at the same cycle as the idle stop control process of FIG.

  In this process, first, in step 21, it is determined whether or not the idle stop flag F_ISTP is “1” and the vehicle speed VP is 0, that is, whether or not the running idle stop is being executed. When the answer is YES, it is determined whether or not the restart flag F_RSTRT is “1” (step 22).

  If the answer to step 22 is NO and the engine 3 is not restarted during the idling stop during traveling, the traveling I / S prohibition flag F_ISTPNG is set to “0” (step 23). The process ends.

  On the other hand, if the answer to step 22 is YES and the engine 3 is restarted while the running idle stop is being executed, the next running idle stop is prohibited, and the duration of the prohibited state is counted up. TM_ISTPNG (hereinafter referred to as “I / S inhibition timer value”) TM_ISTPNG is reset to 0 (step 24), and the traveling I / S inhibition flag F_ISTPNG is set to “1” (step 25). This process ends.

  When the answer to step 21 is NO and the idling stop is not being executed during traveling, it is determined whether or not the traveling I / S prohibition flag F_ISTPNG is “1” (step 26). If the answer to this question is NO and the vehicle is not in the idle stop prohibition state during traveling, the present process is terminated.

  On the other hand, if the answer to step 26 is YES and the idling stop during traveling is prohibited, it is determined whether or not the vehicle speed VP is 0 (step 27). If the answer to this question is YES and the vehicle V stops, the prohibition state of idling stop during traveling is cancelled, and the traveling I / S prohibition flag F_ISTPNG is reset to “0” (step 30).

  If the answer to step 27 is NO, it is determined whether or not the vehicle speed VP is equal to or higher than a predetermined precondition vehicle speed VPHREF (for example, 15 km / h) greater than the I / S start vehicle speed VPISTP (step 28). ). If the answer to this question is YES and the vehicle speed VP ≧ precondition vehicle speed VPHREF is established, the prohibition state of idling stop during traveling is cancelled, and the routine proceeds to step 30 where the traveling I / S prohibition flag F_ISTPNG is set to “0”. Reset.

  If the answer to step 28 is NO, it is determined whether or not the I / S inhibition timer value TM_ISTPNG reset to 0 in the step 24 is equal to or longer than a predetermined time TREF (for example, 30 seconds) (step 29). ). When this answer is YES, that is, when the prohibited state of idling stop during traveling continues for a predetermined time TREF or more, the prohibiting state is canceled, and the process proceeds to the step 30, and the traveling I / S prohibition flag F_ISTPNG is set. Reset to “0”.

  5 and 6 show two operation examples obtained by the idle stop control of the present embodiment described so far. It is assumed that all the conditions other than the conditions (b) and (g) regarding the vehicle speed VP are satisfied among the above-described idle stop execution conditions (a) to (g).

  In the example of FIG. 5, since the vehicle speed VP once exceeds the precondition vehicle speed VPHREF before the time point t1, the traveling I / S prohibition flag F_ISTPNG is set to “0” (step 28 in FIG. 4). 30). For this reason, when the vehicle speed VP becomes equal to or lower than the I / S start vehicle speed VPISTP from this state (t1), the idle stop flag F_ISTP is set to “1”, and the running idle stop is executed.

  If the restart condition is satisfied during the idling stop during traveling (t2), the idling stop is completed and the engine 3 is restarted. At the same time, the traveling I / S prohibition flag F_ISTPNG is set to “1” (steps 21, 22, 25), and the traveling idle stop is prohibited. For this reason, even if the vehicle speed VP becomes equal to or lower than the I / S start vehicle speed VPISTP (t3), the idling stop during traveling is not executed.

  Thereafter, when the vehicle speed VP increases to the precondition vehicle speed VPHREF (t4), the traveling I / S prohibition flag F_ISTPNG is reset to “0” (steps 28 and 30), and the prohibition state of traveling idle stop is released. The For this reason, when the vehicle speed VP becomes equal to or lower than the I / S start vehicle speed VPISTP (t5), the running idle stop is executed.

  In this state, when the restart condition is satisfied and the engine 3 is restarted (t6), the traveling I / S prohibition flag F_ISTPNG is set to “1” again. Thereafter, since the vehicle speed VP has not increased to the precondition vehicle speed VPHREF, the traveling I / S prohibition flag F_ISTPNG is maintained at “1” (t6 to t8). For this reason, even if the vehicle speed VP becomes equal to or lower than the I / S start vehicle speed VPISTP during that time (t7), the idling stop during traveling is not executed.

  After that, when the vehicle speed VP becomes 0 and the vehicle V stops (t8), the traveling I / S prohibition flag F_ISTPNG is reset to “0” accordingly (steps 27 and 30), so that the traveling idle stop is performed. This prohibition state is released, and the idle stop when the vehicle is stopped is executed.

  The operation up to time t13 in the example of FIG. 6 is the same as that up to time t3 in the example of FIG. 5, the running I / S prohibition flag F_ISTPNG is “0” before t11, and the vehicle speed VP starts I / S. When the vehicle speed becomes VPISTP or less, idling stop during traveling is executed (t11). In addition, when the restart condition is satisfied in this state, the engine 3 is restarted, and at the same time, the traveling I / S prohibition flag F_ISTPNG is set to “1”, and the traveling idle stop is prohibited. (T12). For this reason, even if the vehicle speed VP becomes equal to or lower than the I / S start vehicle speed VPISTP (t13), the idling stop during traveling is not executed.

  In this example, thereafter, the vehicle speed VP changes between the two without reaching the pre-condition vehicle speed VPHREF and the value 0. For this reason, the traveling I / S prohibition flag F_ISTPNG is maintained at “1” and the traveling idle stop prohibition state continues. When the continuation time reaches the predetermined time TREF (t14), the traveling I / S prohibition flag F_ISTPNG is reset to “0” (steps 29 and 30 in FIG. 4), and the traveling idle stop prohibition state. Is released.

  Therefore, after that, when the vehicle speed VP becomes equal to or lower than the I / S start vehicle speed VPISTP (t15), the running idle stop is executed. Thereafter, the engine 3 is restarted in response to the establishment of the restart condition, and the traveling I / S prohibition flag F_ISTPNG is set to “1” (t16) to return to the traveling idle stop prohibition state.

  As described above, according to the present embodiment, when the vehicle speed VP becomes equal to or lower than the I / S start vehicle speed VPISTP, the idling stop during running is executed. By being executed reliably, the effect of improving the fuel consumption can be ensured.

  Further, when the engine 3 is restarted during the idling stop during traveling, the traveling I / S prohibition flag F_ISTPNG is set to “1” to prohibit the idling stop during traveling. As a result, the idling stop and restart during traveling are not repeatedly performed frequently during traffic jams and the like, and problems associated therewith can be avoided. For example, it is possible to avoid complications and discomfort in driving the vehicle V due to frequent execution of idle stop and restart during traveling, and suppress deterioration of components related to idle stop and restart, such as the starter motor 8, The lifetime can be extended.

  Further, when the idling stop during traveling is prohibited and the vehicle speed VP becomes 0, the traveling I / S prohibition flag F_ISTPNG is reset to “0” to cancel the prohibition state during traveling idle stop. To do. Thereby, the idling stop at the time of the stop of the vehicle V is performed, so that the frequency of executing the idling stop during traveling can be increased, and the fuel consumption can be further improved.

  In addition, when the vehicle idle speed stop is prohibited and the vehicle speed VP becomes equal to or higher than the precondition vehicle speed VPHREF, the idle idle stop condition is canceled. As a result, when the vehicle V is once out of the traffic jam, the idle stop prohibition state during traveling is canceled, and when the vehicle speed VP becomes equal to or lower than the I / S start vehicle speed VPISTP, Is executed, it is possible to increase the frequency of idling stop during traveling and further improve fuel efficiency.

  Furthermore, when the prohibited state of idle stop during traveling continues for a predetermined time TREF or more, the prohibited state is canceled. As a result, when the vehicle speed VP is neither 0 nor the precondition vehicle speed VPHREF and the traffic jam continues for a long time, it is avoided that the idle stop during the travel is prohibited. The frequency of stop execution can be increased, and fuel consumption can be further improved.

  In addition, this invention can be implemented in various aspects, without being limited to the described embodiment. For example, in the embodiment, as conditions for canceling the prohibition state of running idle stop, the conditions that the vehicle V is stopped, the condition that the vehicle speed VP is equal to or higher than the precondition vehicle speed VPHREF, and the prohibition state of running idle stop are set. Is used for a predetermined time TREF or more, but any one or two of these three conditions may be used.

  Further, the values of the I / S start vehicle speed VPISTP, the precondition vehicle speed VPHREF, and the predetermined time TREF shown in the embodiment are merely examples, and are changed according to the situation. In addition, it is possible to appropriately change the detailed configuration within the scope of the gist of the present invention.
