  The present invention belongs to the technical field of a wireless engine start control device for starting a vehicle engine by remote control based on wireless transmission from a transmitter possessed by a driver.

In general, this type of remote-controlled engine start control device receives an engine start command that is output based on operating a remote control transmitter owned by a driver, and based on this, an accessory on the vehicle side It is configured to output a control command for starting the engine to the circuit, the ignition circuit, and the starter circuit, so that the engine can be started from a remote place away from the vehicle, which is convenient. (For example, patent document 1).
JP 2001-355550 A

  By the way, in terms of transmission devices (transmission devices), there are automatic (automatic transmission) types and manual (manual transmission) types, which are clearly distinguished. On the other hand, in view of the convenience of the remotely operated engine starting device, the driver desires to install a remotely operated engine starting control device regardless of which vehicle the vehicle is equipped with.

  On the other hand, in some automatic transmission vehicles, the shift lever (shift lever) is parked (P: parking (some of the vehicles are set so that the engine can be started even at the neutral (N) position. If the engine is not set to the position, the engine cannot be started, that is, the engine start is executed under the condition that the shift lever is in the P position. There is no problem as in the manual type.

On the other hand, a vehicle equipped with a manual transmission device can start the engine regardless of the position of the shift lever. For this reason, the shift lever is set at a traveling position such as the first speed other than the N position. When the engine is remotely started, the vehicle moves based on the starter motor start. Thus, recently, there is a concern that the vehicle may move even if the parking brake is applied in order to improve the performance of the starter motor, the battery, and the like. And at this time, if the driver is close to the vehicle and notices unexpected movement and takes appropriate measures such as stopping the engine immediately, it does not matter so much, but the driver may notice that it is away from the vehicle. There is a problem that if the vehicle cannot take an appropriate response immediately, for example, the vehicle will run unattended and run away.
For this reason, it is necessary to install a remote-controlled engine start control device only on vehicles with automatic transmission devices. Therefore, when selling a wireless engine start control device as a single component, its specifications This is indicated on the product and package, etc., and caution is given not to install it on a manual transmission type vehicle. There is a problem to be solved by the present invention.

  Furthermore, in the manual type transmission device, there are a clutch switch provided so that the engine cannot be started unless the clutch pedal is depressed and a clutch switch not provided with the clutch switch. In the former type, the clutch pedal is depressed. There is a signal that is input on the same line as the shift position signal of an automatic type vehicle so that the parts can be shared. In such a case, the shift position detection signal that is characteristic of the automatic type is input. There is a problem that the automatic type and the manual type cannot be simply distinguished only by the presence or absence of this, and there is also a problem that the present invention does not solve.

The present invention was created in view of the above-described circumstances to solve these problems. The invention of claim 1 is based on the reception of an engine start command from a remote control transmitter. In the engine start control device configured to output a start control command for starting the engine, the engine start control device includes a determination for determining whether the transmission device of the vehicle is an automatic type or a manual type An engine start control device comprising: means and remote start prohibiting means for prohibiting remote engine start control when it is determined that the determination means is a manual type.

An engine start control device characterized in that it is determined to be a manual type with a switch.
According to a fourth aspect of the present invention, in the first, second, or third aspect, the engine start control device transmits a transmission signal when no detection signal is input for a preset timer time after the ignition key switch is detected to be ON. The engine start control device is characterized in that the device is determined to be a manual type.
According to a fifth aspect of the present invention, in the second, third, or fourth aspect, the detection of closing-opening of the starter circuit is detection of a circuit state that accompanies turning on and off of an inhibitor switch provided in the starter circuit. Is an engine start control device.

According to the first aspect of the present invention, when the manual type transmission device is mounted on the vehicle, the engine start by the remote operation is prohibited, and the manual type vehicle starts the engine by the remote operation and runs away. Can be avoided.
According to the invention of claim 2, since it is determined based on the detection necessary for starting the engine by remote operation that the automatic type vehicle is discriminated, the structure is simplified.
According to the invention of claim 3, when determining the manual type, when it is determined that the starter circuit is open, it can be determined that the clutch switch is provided, and it can be distinguished from the one without the clutch switch. .
According to the invention of claim 4, manual type discrimination can be easily performed.
According to the invention of claim 5, it is possible to make a discrimination by effectively utilizing the ON / OFF switching of the inhibitor switch.

  Next, embodiments of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a transmitter provided with operation switches 1a and 1b for starting and stopping an engine mounted on a vehicle, which is held by a driver. By operating 1a and 1b, a corresponding command signal is output together with various signals such as a necessary encryption signal.

  On the other hand, 2 is an ignition key switch mounted on the vehicle. In addition to the battery circuit 4 that is always connected to the battery 3, the ignition key switch 2 is turned on by key operation to close the accessory circuit 5a.

There is also a vehicle provided with a second starter switch 10 for closing a first starter switch 9 and a starter control circuit 10a to which a starter control unit 10b is connected, and by operating the key of the ignition key switch 2 When the engine is started, the necessary accessories and controls The various operation control is performed are both conventional. In this device, an inhibitor switch (neutral start switch, shift position console switch, switch ON / OFF) is operated by operating a shift lever (not shown) provided in the driver's seat for shifting operation of the automatic transmission device. 9b (also referred to as a shift switch) is provided in the first starter circuit 9a. The inhibitor switch 9b is set to be ON when the shift lever is at the P position and OFF when it is at the R (reverse) position or the D (drive) position. Depending on the type of vehicle, there is one that is set so that the inhibitor switch 9b is turned on even when the shift lever is set to the N (neutral) position. In this case, the present invention can also be implemented at the N position. it can. Further, this inhibitor switch or a similar switch can also be provided in the second starter circuit 10a, and in this case, the present invention can be implemented using the second starter switch circuit 10a. In this embodiment, although not shown, the following description will be made assuming that the starter control unit 10b itself is provided with a switch similar to an inhibitor switch. In some vehicles, the second starter switch circuit 10a is provided with a starter motor 8. In this case, the circuit 10a is used.

  Reference numeral 11 denotes a vehicle-mounted device in a remote-controlled engine start control device. The vehicle-mounted device 11 includes a control circuit 12 (to be described later), a receiving circuit 13 for receiving a command signal transmitted from the transmitter 1, and a necessary circuit. A timer circuit 14 that counts the timer time and a notification device 15 that notifies a buzzer sound, an electronic sound, and the like are provided. The control circuit 12 includes a battery connection circuit 16 connected to the battery circuit 2 and an accessory relay switch 17a, and an accessory connection circuit 17 connected to the accessory circuit 5a and a first ignition relay switch 18a. A first ignition connection circuit 18 connected to the first ignition circuit 6a, a second ignition relay switch 19a, and a second ignition connection circuit 19 connected to the second ignition circuit 7a. A starter relay switch 20a is provided, a first starter connection circuit 20 connected to the first starter circuit 9a, and a second starter relay switch 21a is provided, and a second starter connected to the second starter circuit 10a. Connection circuit 21 and ground Road 22 are provided.

  The accessory connection circuit 17, the first ignition connection circuit 18, and the second ignition connection circuit 19 include an accessory relay switch 17a, a first ignition relay switch 18a, and a second ignition switch provided in each of the circuits 17, 18, and 19, respectively. An accessory sensor 17b, a first ignition sensor 18b, and a second ignition sensor 19b are provided in a state of being connected in parallel with the relay switch 19a, and each of these sensors 17b, 18b, and 19b has a corresponding circuit 17, The voltage (or current) values of 18 and 19 are detected and the detected values are set to be output to the control unit 12. When the start command signal is input and each detected voltage is a preset voltage, the control unit 12 closes the corresponding relay switches 17, 18, and 19, thereby igniting the ignition switch. The drive current is set to flow to the corresponding circuits 5a, 6a and 7a in the state where the key switch 2 is turned on.

Further, the first and second starter connection circuits 20 and 21 include shift position detection sensors 20b and 21b for detecting the shift position of the shift lever in a state of being connected in parallel to the first and second starter relay switches 20a and 21a. Are connected to the shift position detection circuits 20c and 21c. The first and second starter circuits 9a are closed when the inhibitor switch 9b is turned on and off. A starter circuit detection circuit 23 provided with a starter circuit detection sensor 23a for detecting whether the shift position detection sensors 20b and 21b and the starter circuit detection sensor 23a are connected in parallel is connected. (That is, the first and second starter relays are connected between the first starter circuit 9a and the control unit 12). Switch 20a, 21a, the shift position detecting sensor 20b, 21c, the starter circuit detection sensor 23a are connected in parallel.).
And in this thing, when it is in the remote control mode to be described later, when the control unit 12 inputs a start command and detects that the shift position detection sensors 20b and 21b are at the P position, The first and second relay switches 20a and 21a are switched to ON and a driving current is supplied to the first and second starter circuits 9a and 10a to perform remote engine starting.

  Next, when the vehicle-mounted device 11 is mounted on a vehicle, it is determined whether the mounted vehicle is an automatic type or a manual type, and whether to perform remote engine start control based on the determination result is prohibited. The procedure for setting and registering will be described based on the block circuit diagram shown in FIG. 2 and the flowcharts shown in FIGS. As described above, the control unit 12 includes the receiving circuit 13, the timer circuit 14, the accessory sensor 17b, the first ignition sensor 18b, the second ignition sensor 19b, the shift position detection sensors 20b and 21b, and the starter circuit detection sensor 23a. For the alarm 15, the accessory relay switch 17a, the first and second ignition relay switches 18a and 19a, the first and second starter relay switches 20a and 21a A control command is output, and necessary information is registered in the registration unit 24, and information registered by the registration unit 24 is input.

The vehicle-mounted device 11 is connected in parallel to the ignition key switch 2 by means of connectors 25, 26, and 27. By this connection, the battery 3 is turned on, whereby the registration means 24 has been registered so far. The mode information that has been canceled is canceled, and the initial state is entered. Of course, the return to the initial state may be executed when the battery power is cut off.
Then, the control unit 12 determines which type of transmission device is in this initial state, and enters an initial registration mode in which mode registration is performed with the registration unit 24 based on the determination result. In this registration mode, when automatic determination that the transmission device is an automatic type is made, the control unit 12 enters the remote control mode, and thereafter, the remote engine start (using the transmitter 1 as described above) If the manual determination is made that the manual type is performed, the control unit 12 enters the remote control prohibit mode, and thereafter the remote engine start using the transmitter 1 is prohibited. It is set to be.

  When the initial registration mode is entered, it is first determined whether or not the ignition key switch 2 has been turned ON. If YES is determined that the ignition key switch 2 has been turned ON, the first timer is set and the first timer time T1 is set. It is determined whether or not the shift position detection sensors 20b and 21b are detecting the P position (detecting that the engine can be started) within 30 seconds (for example, 30 seconds). When the determination is made, the first timer is reset and the first starter circuit (the same is true for the registration control of the second starter circuit 10a, so the following is omitted) 9a is closed (inhibitor switch 9b is ON). Whether or not the first starter circuit is detected is determined by the first starter circuit detection sensor 23a.

  When it is determined that the first starter circuit 9a is in a closed state, a first notification (for example, notification of “pi”) is made from the notification device 15 as appropriate, and a second timer is set. The shift position detection sensor determines whether or not the shift position detection sensor is in the R position (or may be the D position; hereinafter, description of the D position is omitted) within the second timer time T2 (for example, 10 seconds). When the determination of YES is made that the R position (engine cannot be started) is made by 20b and 21b, the second timer is reset and the first starter circuit detection sensor 23a is moved to the first starter circuit 9a. Is in an open state (inhibitor switch 9b is OFF). If it is determined here that the first starter circuit 9a is in the open state, the first notification is made and the third timer is set as appropriate. Incidentally, these two detections, that is, the detection that the first starter circuit 9a is closed in the shift lever P position detection state and the first starter circuit 9a is in the open state in the shift lever R position detection state. For example, it can be recognized that the transmission device mounted on the vehicle is an automatic type, but in the present embodiment, further confirmation is made in order to increase the certainty thereof.

That is, when the shift position detection sensors 20b and 21b detect the P position and the first starter circuit 9a is in the open state within the third timer time T3 (for example, 10 seconds), the first When the notification is made and the fourth timer is set, and the ignition key switch 2 is turned OFF within the fourth timer time T4 (for example, 10 seconds), it is determined that the transmission device of the vehicle is an automatic type, While the timer is reset, a second notification sound (for example, “pi, pi, pi, pi”) is generated as the aptitude registration is made to the alarm device 15, and the transmission device mounted on the vehicle is an automatic type. This is registered in the registration means 24, and thereafter the remote control mode is executed.
If there is no appropriate detection corresponding to each of the second, third and fourth timer times, a notification sound (e.g., “pee”) is generated as an overtime, and the initial registration mode state is restored. It is supposed to be.

  On the other hand, first, if NO (first timer time T1 has elapsed) is determined that the shift lever position detection sensors 20b and 21b have not been detected within the first timer time T1, the time is over. When two notifications (for example, “Peep, Peep”) are made, it is determined whether or not the passage of the first timer time T1 has been counted a predetermined number of times (for example, three times). This vehicle is not an automatic type and is equipped with a manual type transmission device with or without a clutch switch, and a fourth notification (for example, “continuous long beeping sound”) is pronounced to notify the clutch. It is equipped with a switch-type transmission device (this is the case when time is exceeded without any operation) Switch registers to that effect to the registration unit 24 as being equipped with a free manual type transmission arrangement, is configured to prohibit the engine start by remote control is a remote control inhibition mode.

  On the other hand, if it is detected that the shift lever is in the P position within the first timer time T1, but the first starter circuit 9a is opened, the shift position detection sensor 20b is used in the manual type with a clutch switch. In addition, the signal on the clutch switch side is the same signal that the shift lever is in the P position, but since the first starter circuit 9a is open, it is determined that the transmission device is a manual type with a clutch switch, At the same time as the fourth notification, the transmission device is registered as a manual type with a clutch switch, and the remote control prohibit mode in which the remote control is not executed after the third buzzer for notifying the sound is generated.

  In addition, in this case, it is assumed that the determination in the engine startable state within the first timer time T1 is cleared for some reason, and the engine cannot be started during the second timer time T2. In other words, if it is determined that the first starter circuit 9a is closed while the shift lever is detecting the R position, the fourth notification is made and the transmission device is equipped with a clutch switch. This is registered as a manual type, and the third buzzer for notifying that is set to be in a remote control prohibit mode in which remote control is not executed after sounding.

  In the embodiment of the present invention configured as described above, when a remotely operated engine starting device is mounted on a vehicle, when the vehicle is mounted with a manual transmission device, the vehicle-mounted device 11 has a predetermined After the circuit is connected, when the ignition key switch 2 is turned ON, the first starter circuit 9a is closed and the shift lever is not started when the shift lever is in the engine startable state, that is, set to the P position. In a possible state, that is, in the state set to the R position, it is registered as a condition that it is detected that the first starter circuit 9a is opened, and the remote control mode in which the engine can be started by remote operation is set. Startup can be performed remotely.

  On the other hand, after the ignition key switch 2 is turned on, if no detection signal is input within a predetermined time period, or the opening of the first starter circuit 9a is detected, a predetermined timer time (the first time in the embodiment) If there is a detection signal indicating that the engine can be started during the timer time) and there is no detection signal indicating that the first starter circuit 9a has been closed, it is determined that the manual transmission device is a manual type, The former type is a manual type, with any type with or without a clutch switch, and the latter type is registered with a type with a clutch switch, and in any case as a remote control prohibit mode, Thereafter, the engine cannot be started by remote control.

  As described above, in the case where the present invention is implemented, when a remotely operated engine start control device is mounted on a vehicle, it is determined whether the transmission device of the vehicle is a manual type or an automatic type. The engine can be started by remote control only when it is determined to be an automatic type, and if it is a manual type, the engine start by remote control is prohibited. As described above, it is possible to avoid the problem that the vehicle unexpectedly moves (runaway), and it can be used exclusively for the automatic type.

  In addition, in this case, whether the transmission device is an automatic type or a manual type is determined by detecting the shift position of the shift lever necessary for starting the engine and detecting whether the starter circuit is open or closed. Since it is used effectively, the structure can be simplified.

  In addition, in this case, when it is determined that the starter circuit is opened in the determination of being a manual type, it is possible to further determine that the clutch switch is provided, which is convenient.

  Of course, the present invention is not limited to the above-described embodiment, and in the above-described embodiment, the starter circuit is closed when the shift lever is operated from P position → R position → P position → The accuracy of reliability is improved by detecting that the opening is closed, but the number of operations and the number of detections are further increased. For example, the operation is performed from the P position → the R position → the P position → the R position → the P position. In this case, it may be determined that the starter circuit is an automatic type by detecting that the starter circuit is closed → open → closed → open → closed. It can be made reliable.
