Description

  The present invention relates to a start control device that performs start control of a vehicle based on a signal received from a remote operation terminal, or in particular, a highly versatile start control device that can be used regardless of the configuration on the vehicle side. It is about.

  A vehicle generally includes a starter switch that controls engine start, an ignition switch that controls engine ignition, and an accessory switch that controls power supply to an on-vehicle electric device.

  Here, when the starter switch is turned on, a large amount of electric power is required for the rotation of the starter motor. Therefore, if the accessory switch is turned on at the same time, the power supply to the in-vehicle electric device becomes unstable.

  For this reason, conventionally, these switches (starter switch, ignition switch, accessory switch) are configured to be physically turned on and off by the operation of the ignition key by the driver, and the starter switch and the accessory switch are turned on simultaneously. It was prevented from becoming.

  However, in recent years, there has been a demand to execute vehicle start control without an ignition key inserted by a remote operation terminal such as a remote key, and on / off of an ignition system switch such as a starter switch, an ignition switch, and an accessory switch by a relay circuit. A configuration for performing control is adopted.

  However, since the starter switch and the accessory switch control a large current, contact welding of the switch (control relay) may occur, and the starter switch and the accessory switch may be turned on at the same time by the welding.

  Thus, Patent Document 1 discloses a technique for turning off other control relays and then turning off a sub-relay shared by each switch when contact welding occurs in the switch (control relay). Further, Patent Document 2 discloses an engine starter having improved failure detection capability of contact means that bypasses the engine start contact.

  By the way, some vehicles use a plurality of ignition and starter signals. In this case, the start control device needs to be provided with a corresponding number of ignition switches and starter switches. However, creating separate start control devices for vehicles with a single ignition and starter signal and for vehicles that use multiple signals increases costs, so the ignition and starter signals There is a need for a general-purpose start control device that can be used alone or in a plurality.

  Further, from the viewpoint of cost reduction, it is desirable that switches that are not used can be deleted and connected only when necessary for the vehicle to be mounted.

  A vehicle remote starter, which is a preferred embodiment of a start control device according to the present invention, will be described in detail below with reference to the accompanying drawings.

  First, the concept of the present invention will be described with reference to FIG. In the figure, the remote control device has an ignition system line consisting of an accessory (ACC) line, an ignition (IG) line, a starter 1 (ST1) line, and a starter 2 (ST2) line.

  The accessory line is a path for supplying power to the vehicle-mounted electrical device, and is controlled by the accessory switch SWa. The ignition line is a path for supplying power to the ignition control device, and is controlled by the ignition switch SWi.

  The starter 2 line is a path for supplying power to an engine starter (cell motor), and is controlled by a starter switch SWs2. Furthermore, the starter 1 line is a path for supplying information related to engine start control for control of other devices, and is controlled by a starter switch SWs1.

  The sub-relay RL1 is a fail-safe mechanism that cuts off power to the accessory switch SWa and the ignition switch SWi, and the sub-relay RL2 is a fail-safe mechanism that cuts off power to the starter switch SWs1 and the starter switch SWs2.

  The drive output unit 15 is means for performing on / off control of the accessory switch SWa, the ignition switch SWi, the starter switch SWs1, the starter switch SWs2, the sub relay RL1, and the sub relay RL2 using the voltage of the battery 22.

  Furthermore, in order to perform welding determination and open determination for each switch, the output monitor unit 16 obtains the output of the ignition system switch including the accessory switch SWa, the ignition switch SWi, the starter switch SWs1, and the starter switch SWs2.

  Specifically, the output monitor unit 16 outputs the accessory switch SWa at the terminal 16c, the output from the ignition switch SWi at the terminal 16d, the output from the starter switch SWs1 at the terminal 16e, and the output from the starter switch SWs2 at the terminal 16g. , Get each.

  When this remote starter is mounted on a vehicle using both the starter 1 line and the starter 2 line, the starter switch SWs1 is necessary, and the output monitor unit 16 acquires the output of the starter switch SWs1 at the terminal 16e.

  However, when the remote starter is mounted on a vehicle that uses only the starter 2 line (not the starter 1 line), the starter switch SWs1 is not necessary. Therefore, in the present invention, when the starter switch SWs1 is not necessary, the cost can be reduced by omitting the starter switch SWs1.

  Further, when the starter switch SWs1 is omitted, the terminal 16e is connected to the starter switch SWs2 via the auxiliary circuit 18. Therefore, not the output of the starter switch SWs1 but the output of the starter switch SWs2, that is, the same output as that of the terminal 16g is obtained from the terminal 16e.

  As described above, when the starter switch SWs1 is deleted, the state of the starter switch SWs1 can be virtually determined by inputting the state of the other switch (here, the starter switch SWs2) as the state of the starter switch SWs1. And the occurrence of errors can be avoided.

  Next, a specific configuration example of the remote starter according to the embodiment of the present invention will be described. First, FIG. 2 shows a configuration diagram in the case where one starter line is necessary. As shown in the figure, the remote starter 10 is connected to a battery 22, a door opening / closing switch 23, a door lock switch 24, a bonnet switch 25, an antenna 29, a starter relay 31, and a hazard lamp 33, as well as a shift position 26 and an engine. Data on the rotational speed 27 is acquired.

  The battery 22 is further connected to an ignition (IG) key switch 21, and the starter relay 31 is connected to a starter motor 32.

  The IG key switch 21 controls an accessory line, an ignition 1 line, a starter 1 line, an ignition 2 line, and a starter 2 line when the driver inserts an ignition key and is manually operated. Here, a configuration in which two ignition lines are provided in addition to the starter line is shown.

  Two ignition lines are provided so that one inputs signals to an ECU related to engine control, and the other inputs signals to an ECU other than engine control (for example, an ECU that controls a wiper or a door lock). Because. Thereby, even if there is some trouble other than the engine control ECU, there can be no problem in the engine control ECU.

  The door open / close switch 23 is a switch corresponding to the open / closed state of the vehicle door, and the door lock switch 24 is a switch corresponding to the locked state of the vehicle door. The bonnet switch 25 is a switch corresponding to the open / close state of the bonnet.

  The antenna 29 receives a signal from a transmitter 28 (for example, a remote key) possessed by the driver and outputs the signal to the remote starter 10. The starter relay 31 is a control switch that is connected to the starter 2 line and operates the starter motor 32 when the engine is started. The hazard lamp 33 warns the surroundings of the behavior of the host vehicle by simultaneously blinking the left and right direction indicator lamps. In this embodiment, the hazard lamp 33 is used as a notification means for notifying the driver of the remote start control result. .

  The remote starter 10 includes a main control unit 11, a reception processing unit 12, an input processing unit 13, a power supply unit 14, a drive output unit 15, an output monitoring unit 16, an output processing unit 17, a sub relay RL1, a sub relay RL2, and an ignition system switch. (Accessory (ACC) switch SWa, ignition (IG) switches SWi1, SWi2, starter (ST) switch SWs2) and an external connection terminal 19.

  In FIG. 2, the external connection terminal 19 is connected to an external starter switch SWs1. The reason why the starter switch SWs1 is provided externally in this manner is that the starter switch SWs1 can be installed only when the starter switch SWs1 is necessary.

  The remote starter 10 can replace the function of the IG key switch 21 by controlling the accessory switch SWa, the ignition switches SWi1 and SWi2, and the starter switches SWs1 and SWs2.

  The reception processing unit 12 outputs a signal received by the antenna 29 to the main control unit 11. Further, the input processing unit 13 outputs the state of the door opening / closing switch 23, the door lock switch 24 and the bonnet switch 25, the shift position 26 and the engine speed 27 to the main control unit 11.

  The power supply unit 14 acquires from the battery 22 and supplies power necessary for on / off control of the accessory switch SWa, the ignition switches SWi1, SWi2, the starter switches SWs1, SWs2, the sub relay RL1, and the sub relay RL2 by the drive output unit 15. The output processing unit 17 is a unit that executes control of the hazard lamp 33.

  The output monitor unit 16 monitors the outputs of the sub-relays RL1 and RL2, the accessory switch SWa, the ignition switch SWi, and the starter switch SWs and outputs them to the main control unit 11.

  Specifically, the output monitor unit 16 acquires the output of the sub-relay RL1 at the terminal 16a and the output of the sub-relay RL2 at the terminal 16b. The output of the accessory switch SWa is at the terminal 16c, the output of the ignition switch SWi1 is at the terminal 16d, the output of the starter switch SWs1 is at the terminal 16e, the output of the ignition switch SWi2 is at the terminal 16f, and the output of the starter switch SWs2 is at the terminal 16g. , Get each.

  The main control unit 11 is a control unit that controls the remote starter 10 as a whole. Based on signal inputs from the reception processing unit 12, the input processing unit 13, and the output monitor 16, the main control unit 11 is connected to the drive output unit 15 and the output processing unit 17. Perform signal output.

  Specifically, when the reception processing unit 12 receives a remote start instruction from the transmitter 28, the main control unit 11 controls the accessory switch SWa, the ignition switches SWi1, SWi2, and the starter switches SWs1, SWs2 to perform start control. Execute. Note that when the signal input from the input processing unit 13 indicates opening of the door, opening of the lock, opening of the hood, etc., start control is not performed. Similarly, the start control is not performed when the shift position 26 is other than “parking”.

  The engine speed 27 is used to determine whether the engine has started after the starter switch SWs2 is turned on. It can also be used to determine whether or not the engine has been warmed up when performing the control of “turn off the engine at the end of warming up after remote start”.

  Next, FIG. 3 shows a configuration diagram when one starter line is unnecessary. In the configuration shown in FIG. 2, the starter switch SWs 1 is connected to the external terminal 19, but in the configuration shown in FIG. 3, the external terminal 19 is connected to the starter 2 line via the auxiliary circuit 18. Other configurations are the same as those in FIG.

  In this way, the configuration can be easily switched by simply changing the connection destination of the external connection terminal 18. In addition, when the starter 1 line is unnecessary, the starter switch SWs1 itself can be omitted, and the cost can be reduced.

  Next, the control output for each switch and the state of each switch will be described with reference to FIGS. First, the case where the starter switch SWs1 is connected will be described with reference to FIG. 4 to 7, the signals of IG1 and IG2 are not synchronized, but this is caused by operating the IG of the peripheral device on or off with one ignition line and then operating the engine ECU on the other ignition line. The IG is turned on or off to ensure that the engine ECU and peripheral devices operate in a coordinated manner (in order to allow the peripheral device to input signals to the engine ECU more reliably).

  When receiving a remote start instruction (engine starter start signal) from the transmitter 28 at time T100, the main control unit 11 performs welding determination of the sub-relay RL1 and the sub-relay RL2, and if not welded to the sub-relay RL1 and the sub-relay RL2. And ON control is performed (time T101).

  Next, the welding determination of the accessory switch SWs, the ignition switches SWi1 and SWi2, and the starter switches SWs1 and SWs2 is executed, and the on control for the accessory switch SWa is performed at time T102. Further, after a predetermined time elapses after the on-control of the accessory switch SWa, it is determined whether the accessory switch SWa is correctly turned on in response to the on-control (open determination of the accessory switch SWa). This predetermined time is provided to prevent erroneous determination due to chattering that occurs when the accessory switch SWa is switched from OFF to ON. Similarly, the delay time from when each control output is switched from OFF to ON or from ON to OFF in FIG. 4 until the welding determination or the open determination is started is based on chattering due to this switch change. .

  Subsequently, at time T103, the ignition switch SWi1 is turned on, and the ignition switch SWi1 is determined to be open. Further, at time T104, the ignition switch SWi2 is turned on, and the ignition switch SWi2 is determined to be open.

  Then, the OFF control for the accessory switch SWa is executed at time T105, and the welding determination of the accessory switch SWa is performed after a predetermined time. The predetermined time at this time takes into consideration the time required for removing the influence of the residual charge after the accessory switch SWa is turned off, for example, the time required for discharging the capacitor. After that, at time T106, the on-control for the starter switch SWs2 is executed to determine whether the starter switch SWs2 is open. Further, on control for starter switch SWs1 is executed at time T107, and open determination of starter switch SWs1 is performed.

  Thereafter, the starter switch SWs2 is turned on to start the engine. Therefore, the starter switch SWs1 is turned off at time T108 and the starter switch SWs2 is turned off at time T109, so that the starter switch is welded. In addition, on control for the accessory switch SWa is executed at time T110.

  Thereafter, normal control is performed for each switch. In the same figure, in response to receiving a remote start end instruction (engine starter end signal) from the transmitter 28, the ignition switch SWi2 is turned off at time T111, and the ignition switch SWi1 is turned off at time T112. Further, the accessory switch SWa is turned off at time T113, and the sub relay RL1 and the sub relay RL2 are turned off at time T114.

  Here, the state of the starter switch SWs2 (the state of the switch input to the terminal 16g) acquired by the output monitor unit 16 by the on control (time T106) for the starter switch SWs2 is “on state”, and the off control for the starter switch SWs2 is performed. The state of the starter switch SWs2 acquired by the output monitor unit 16 at (time T109) is “off state”. That is, the control state for the switch matches the switch state.

  Similarly, the state of the starter switch SWs1 (the state of the switch input to the terminal 16e) acquired by the output monitor unit 16 by the on control (time T107) for the starter switch SWs1 is “on state”, and the off control for the starter switch SWs1. The state of the starter switch SWs2 acquired by the output monitor unit 16 at (time T108) is “off state”. That is, the control state for the switch matches the switch state.

  Here, when the starter switch SWs1 is simply deleted, the control output for each switch and the state of each switch are as shown in FIG. In this figure, the control for each switch is the same as in FIG.

  Since the starter switch SWs1 does not exist, even if the start control (time T107) is performed on the starter switch SWs1, the state of the starter switch SWs1 acquired by the output monitor unit 16 (the state of the switch input to the terminal 16e) is “off”. "State" remains. Therefore, the main control unit 11 determines that an open failure has occurred in the starter switch SWs1.

  Therefore, when the external connection terminal 19 is connected to the starter 2 line as shown in FIG. 3, the control output for each switch and the state of each switch are as shown in FIG. In this figure, the control for each switch is the same as in FIG.

  Since the external connection terminal 19 is connected to the starter 2 line, the starter switch SWs2 acquired by the output monitor unit 16 by the ON control (time T106) with respect to the starter switch SWs2 (the state of the switch input to the terminal 16g). In addition, the state of the switch input to the terminal 16g is also “ON”, and in addition to (the state of the switch input to the terminal 16g) by the OFF control (time T109) for the starter switch SWs2, the switch input to the terminal 16g The state is also an “off state”.

  Therefore, it is not determined that an open failure has occurred in starter switch SWs1 as shown in FIG. However, after the starter switch SWs1 is switched from on to off, the time until the welding determination is started (from time T108 to time T109), and after the starter switch SWs2 is switched from on to off, the welding determination is started. The time (from time T109 to time T110) is set to the same length for the purpose of preventing chattering. Since the start control of the starter switch SW1 is earlier than the start control of the starter switch SW2, the timing of welding determination for the starter switch SWs1 is earlier than the timing of welding determination for the starter switch SWs2. It is determined that a welding failure has occurred in the switch SWs1.

  Therefore, in the remote starter 10, the determination timing of the starter switch SWs1 is set in advance so as to match the determination timing of another ignition system switch (specifically, a switch connected to the monitoring terminal of the starter switch SWs1). Yes.

  For example, when the starter switch SWs2 is connected to the terminal 16e as shown in the present embodiment, the main control unit 11 sets the determination timing for the starter switch SWs1 by the determination control unit 11 that performs open determination or welding determination. Change to match the determination timing of the starter switch SWs2.

  As a result, the control output for each switch and the state of each switch are as shown in FIG. In this figure, the control for each switch is the same as in FIG. 4, but it is possible to avoid the determination of the open failure and the determination of the welding failure by matching the determination timing for the starter switch SWs1 with the determination timing of the starter switch SWs2. it can.

  Thus, by changing the determination timing, even if the control output is the same, it can be used regardless of the configuration on the vehicle side, and versatility can be easily improved.

  When the determination timing is changed, it may be automatically adjusted to the connection destination switch (starter switch SWs2 here), or the connection destination switch and the original switch (starter switch SWs1 here) are determined. You may make it match with the later one.

  Next, the processing operation of the remote starter 10 will be described. FIG. 8 is a flowchart for explaining processing executed when the remote starter 10 receives a remote start instruction from the transmitter 28. The processing flow shown in FIG. 8 is repeated during start control by the remote starter 10. Executed.

  As shown in FIG. 8, when receiving the remote start instruction, the remote starter 10 first turns on the sub-releases RL1 and RL2 (step S101). Subsequently, the ACC line (accessory switch SWa) is turned on for the first time (step S102), the IG1 line (ignition switch SWi1) is turned on (step S103), and the IG2 line (ignition switch SWi2) is turned on (step S104). Do.

  Then, after the first OFF control of the ACC line (step S105), the ST2 line (starter switch SWs2) ON control (step S106) and the ST1 line (starter switch SWs1) ON process (step S107) are performed.

  Furthermore, after the ST1 line (starter switch SWs1) is turned off (step S108) and the ST2 line (starter switch SWs2) is turned off (step S109), the ACC line is turned on for the second time (step S110). To finish the process.

  Next, each process shown in FIG. 8 will be described in detail. FIG. 9 is a flowchart illustrating details of processing in the sub-relay RL ON control shown as step S101 in FIG. In this processing flow, the remote starter 10 first determines whether start control is permitted (step S201).

  As a result, when the start control is permitted (step S201, Yes), it is determined whether or not both the sub-relay RL1 and the sub-relay RL2 are on (step S202).

  When the sub relays RL1 and RL2 are not in the on state (No at Step S202), the drive output unit 15 performs the on control of the sub relay RL1 (Step S203) and the on control of the sub relay RL2 (Step S204).

  Then, the control timing of the first ACC on (step S102 in FIG. 8) is set (step S205), and the welding determination of the sub-relays RL1 and RL2 is prohibited (step S206).

  Further, the welding determination of the ACC line (accessory switch SWa) is permitted (step S207), the welding determination of the IG1 line (ignition switch SWi1) and the IG2 line (ignition switch SWi2) is permitted (step S208), and the ST1 line (starter) The welding determination of the switch SWs1) and the ST2 line (starter switch SWs2) is permitted (step S209).

  After this step S209 ends, or when the start control is not permitted (step S201, No), or when the sub relays RL1 and RL2 are in the on state (step S202, Yes), the remote starter 10 performs the sub relay RL on process.

Similarly, the welding determination of the IG1 line and the IG2 line is prohibited (step S306), and the welding determination of the ST1 line and ST2 line is prohibited (step S307).

  Thereafter, the remote starter 10 sets the determination start timing of the ACC open determination (step S308). The start timing of this determination is set in consideration of chattering due to a switch change as already described. Specifically, it is preferable to set the time around 50 milliseconds to 100 milliseconds after the ACC on control in step S303. Thereafter, when setting the determination start timing, the timing is similarly set in consideration of chattering.

  After step S308, or when the control timing is not the first ACC on (step S301, No), or when the start control is not permitted (step S302, No), the remote starter 10 performs the ACC on first control. And the process proceeds to the on control of the IG1 line shown as step S103 in FIG.

  Then, the control timing of the ON control of the ST2 line (step S106 in FIG. 8) is set (step S603), and the open determination of the ACC line is prohibited (step S604).

  Thereafter, the remote starter 10 sets the determination start timing of the ACC welding determination (step S605). The start timing of this determination is set in consideration of the influence of the residual charge as already described. Although the specific length depends on the capacitance of the capacitor, for example, it is preferable to set it to about 1 second after the ACC off control in step S602. Thereafter, when the determination start timing is set, the timing is similarly set in consideration of the residual charge.

  After step S605 is completed, or when it is not the first control timing of ACC off (step S601, No), the remote starter 10 finishes the first control of ACC off and turns on the ST2 line shown as step S106 in FIG. Transition to control.

Here, the start timing of the ST1 welding determination is set not at a predetermined time after the ST1 off control as described above, but at the same time as the determination start timing of the ST2 line welding determination. In addition, after the end of step S904, the remote starter 10 prohibits the ST1 line open determination (step S905).

  After the end of step S905, or when it is not the ST1 off control timing (step S901, No), the remote starter 10 finishes the ST1 off control and shifts to the ST2 line off control shown as step S109 in FIG. .

Further, if the sub-relay RL1 is not welded (step S1204, No), the welding determination of the sub-relay RL2 is performed (step S1205).

  If the sub-relay RL2 is not welded (step S1205, No), the process is terminated as it is.

  On the other hand, when sub-relay RL1 is welded (step S1204, Yes) or when sub-relay RL2 is welded (step S1205, Yes), remote starter 10 prohibits start control (step S1206). ), The process is terminated.

  Here, the prohibition of the start control is set by setting a predetermined flag, and this flag may be referred to when determining whether the start control is permitted. Further, the sub relay RL1 may be controlled to be turned off in accordance with the start control prohibition. Thereafter, when starting control is prohibited, a predetermined flag is set similarly, and the sub-relay RL1 may be turned off.

  Next, ACC failure determination will be described. FIG. 20 is a flowchart for explaining the processing operation of the remote starter 10 in determining the failure of the ACC line. As shown in the figure, in the ACC failure determination, first, the output of the ACC line is fetched (step S1301).

As shown in FIG. 21, in the IG failure determination, first, output capture of the IG1 line (step S1401) and output capture of the IG2 line (step S1402) are executed.

If the IG1 welding determination is permitted (step S1403, Yes), the IG1 line welding determination is performed (step S1404). As a result, if the IG1 line is welded (step S1404, Yes), start control is prohibited (step S1405).

  If the IG1 open determination is permitted (step S1411, Yes), the remote starter 10 performs an open determination on the IG1 line (step S1412). As a result, if the IG1 line has an open failure (step S1412, Yes), start control is prohibited (step S1413).

  After the start control is prohibited in step S1413, or when the IG1 open determination is not permitted (step S1411, No), or when the IG1 line is not open failure (step S1412, No), the remote starter 10 opens IG2. It is determined whether or not it is the determination start timing (step S1414).

  After step S1415 or when it is not the start timing of the IG2 open determination (step S1414, No), the remote starter 10 determines whether the IG2 open determination is permitted (step S1416).

  If IG2 open determination is permitted (step S1416, Yes), remote starter 10 performs IG2 line open determination (step S1417). As a result, if the IG1 line has an open failure (step S1417, Yes), the remote starter 10 prohibits start control (step S1418) and ends the process.

  On the other hand, if the IG2 open determination is not permitted (step S1416, No), or if the IG2 line is not open failure (step S1417, No), the remote starter 10 ends the IG failure determination as it is.

  Next, ST failure determination will be described. 23 to 24 are flowcharts for explaining the processing operation of the remote starter 10 in the ST line failure determination. As shown in FIG. 23, in ST failure determination, first, ST1 line output capture (step S1501) and ST2 line output capture (step S1502) are executed.

  Next, the remote starter 10 determines whether or not it is the start timing of ST1 welding determination (step S1503), and if the result is the start timing of ST1 welding determination (step S1503, Yes), ST1 The welding determination is permitted (step S1504).

  After step S1504 or when it is not the start timing of ST1 welding determination (step S1503, No), remote starter 10 determines whether ST1 welding determination is permitted (step S1505).

  If ST1 welding determination is permitted (step S1505, Yes), remote starter 10 performs ST1 line welding determination (step S1506). As a result, if the ST1 line is welded (step S1506, Yes), the sub-relay RL2 is turned off (step S1507) and the start control is prohibited (step S1508).

  After the start control is prohibited in step S1508, or when ST1 welding determination is not permitted (step S1505, No), or when the ST1 line is not welded (step S1506, No), the remote starter 10 then performs ST2. It is determined whether or not it is a welding determination start timing (step S1509), and if it is the ST2 welding determination start timing (step S1509, Yes), the ST2 welding determination is permitted (step S1510).

  After step S1510 or when it is not the start timing of ST2 welding determination (step S1509, No), remote starter 10 determines whether ST2 welding determination is permitted (step S1511).

  If ST2 welding determination is permitted (step S1511, Yes), remote starter 10 performs ST2 line welding determination (step S1512). As a result, if the ST2 line is welded (step S1512, Yes), the sub-relay RL2 is turned off (step S1513) and the start control is prohibited (step S1514).

  After starting control is prohibited in step S1514, or when ST2 welding determination is not permitted (step S1511, No), or when the ST2 line is not welded (step S1512, No), the remote starter 10 is As shown in FIG. 24, it is determined whether or not it is the start timing of ST1 open determination (step S1515), and if it is the start timing of ST1 open determination (step S1515, Yes), ST1 open determination is permitted. (Step S1516).

  After step S1516 or when it is not the start timing of ST1 open determination (step S1515, No), the remote starter 10 determines whether ST1 open determination is permitted (step S1517).

  If ST1 open determination is permitted (step S1517, Yes), remote starter 10 performs ST1 line open determination (step S1518). As a result, if the ST1 line has an open failure (step S1518, Yes), the sub-relay RL2 is turned off (step S1519) and the start control is prohibited (step S1520).

  After starting control is prohibited in step S1520, or when ST1 open determination is not permitted (step S1517, No), or when the ST1 line is not open failure (step S1518, No), the remote starter 10 then It is determined whether or not it is the start timing of ST2 open determination (step S1521). As a result, if it is the start timing of ST2 open determination (step S1521, Yes), the ST2 open determination is permitted (step S1522). .

  After step S1522, or when it is not the start timing of ST2 open determination (step S1521, No), remote starter 10 determines whether or not ST2 open determination is permitted (step S1523).

  If ST2 open determination is permitted (step S1523, Yes), remote starter 10 performs ST2 line open determination (step S1524). As a result, if the ST2 line has an open failure (step S1524, Yes), the sub-relay RL2 is turned off (step S1525), the start control is prohibited (step S1526), and the process ends.

  On the other hand, when the ST2 open determination is not permitted (step S1523, No), or when the ST2 line is not open failure (step S1524, No), the remote starter 10 ends the ST failure determination as it is.

  In this ST failure determination, the ST1 welding determination start timing (step S1503) and the ST2 welding determination timing (step S1509) indicated by shading in the figure assume a case where the starter switch SWs1 is not connected as described above. It is set a predetermined time after the start control of the starter switch SWs2 (that is, at the same timing).

  Note that the ST1 welding determination start timing may be determined based on the connection state of the starter switch SWs1. In this case, ST1 off control, which is processing for determining ST1 welding determination start timing, uses the processing shown in the flowchart of FIG.

  In the ST1 off process shown in FIG. 25, it is determined whether or not it is the ST1 off control timing (step S1601), and if it is the ST1 off control timing (step S1601, Yes), the ST1 off output is executed. Until the timing of ST2 off control is set (step S1603), the process is the same as steps S901 to S903 of the ST1 off process shown in FIG.

  After the ST2 OFF control timing set (step S1603), it is determined whether the ST1 line is connected (step S1604). If the ST1 line is not connected (step S1604, No), the ST1 welding determination is started. The timing is set to T2, which is the same time as the ST2 welding determination timing (step S1606).

  On the other hand, if the ST1 line is connected (step S1604, Yes), the ST1 welding determination start timing is set to time T1 in consideration of chattering and residual charge generated by the ST2 off control in step S1602 ( Step S1605).

  After the ST1 welding determination start timing is set (step S1605 or step S1606), the ST1 line open determination is prohibited (step S1607). Furthermore, after step S1607 ends or when the ST1 off control timing is not reached (step S1601, No), the remote starter 10 ends the ST1 off control, and performs the ST2 line off control shown as step S109 in FIG. Transition.

  In this way, by changing the ST1 welding determination timing based on the connection state of ST1, the optimal determination timing can be taken even when ST1 is connected. Note that the connection state of ST1 may be input by the user, or the remote starter 10 may automatically determine.

  FIG. 26 shows a flowchart of ST failure determination processing for automatically determining the connection state of ST1. In the ST failure determination shown in the figure, first, the output capture of the ST1 line (step S1701) and the output capture of the ST2 line (step S1702) are executed.

  If a change from ST1 off to ST1 on is detected (step S1703, Yes), it is further determined whether or not there is a change from ST2 off to ST2 on (step S1704).

  As a result, when there is a change from ST2 off to ST2 on, that is, when ST1 changes in accordance with the change in ST2, it is determined that the ST1 connection flag is “0”, that is, ST1 is in a disconnected state. . The ST1 connection flag has an initial value “1”, that is, the ST1 connection state.

  After step S1705, or when there is no change from ST1 off to ST1 on (step S1703, No), or when there is no change from ST2 off to ST1 on (step S1704), step S1503 shown in FIG. Transition.

  Thus, the connection state of ST1 can be automatically determined by comparing the outputs of ST1 and ST2.

  As described above, in the remote starter according to the present embodiment, the configuration can be easily switched only by changing the connection destination of the external connection terminal 18. In addition, when the starter 1 line is unnecessary, the starter switch SWs1 itself can be omitted, and the cost can be reduced.

  Furthermore, by changing the timing of the switch state determination, the determination can be performed easily and accurately regardless of the configuration change and without changing the control output.

  In this embodiment, the case where a remote starter corresponding to a vehicle with two starter lines and an ignition line is mounted on a vehicle with one starter line has been described as an example. However, the control line of the remote starter can be configured by any number. Further, the present invention can be applied to any control line such as when the number of ignition lines of the remote start control device exceeds the number of ignition lines on the vehicle side. Furthermore, the line connected in place of the switch to be deleted is not limited to the same system (the starter 1 line is connected to the starter 2 line as shown in the embodiment), but is connected to an arbitrary control line. It ’s good.

  Further, in the present embodiment, the remote starter that performs the start control based on the remote start instruction from the transmitter 28 has been described as an example, but the use of the present invention is not limited to this and is set. The present invention can be widely applied to vehicle start control using a relay switch, such as automatic start based on a schedule and start of a vehicle that does not use an ignition key.

  As described above, the start control device according to the present invention is useful for start control of a vehicle, and is particularly suitable for start control by control of a relay switch.
