Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an engine start control device, and more particularly to an engine start control device for starting an engine by one-touch operation.

[0002]

2. Description of the Related Art In recent years, automobiles have been required to have not only improved basic performance and safety but also improved operability. Conventionally, as one example, an engine start control device having a smart ignition function has been proposed.

[0003] The smart ignition function means that the owner of the vehicle (driver) operates a push button switch or the like provided in the vehicle compartment when the vehicle and the key are wirelessly collated by ID and confirmed as a correct ID. It is a function to start the engine by operating (pushing) the section. That is, it is a function that allows the engine to be started without using a mechanical key.

In order to reliably start the engine in such an engine start control device, it is important to stop the start of the starter motor. For example, when the temperature of the engine is low or when the engine is left for a long time, it is difficult to start the engine. For this reason, if the start of the starter motor is stopped immediately after the start of the engine is confirmed based on the output signal from the alternator or the like, there is a possibility that the engine may stall due to misfire. Therefore, in the conventional engine start control device, after the start of the engine is confirmed based on the output signal from the alternator and the like, the drive of the starter motor is stopped after a predetermined time has elapsed. That is, by keeping the driving of the starter motor for a predetermined time after the engine is started, the engine is reliably started.

[0005]

However, in the conventional engine start control device, the starter motor is driven until the engine starts. For this reason, when the engine is difficult to start, the starter motor is driven for a long time by a temporary operation (instantaneous operation) of the operation unit. Therefore, the driver may feel a sense of incongruity that the system on the vehicle side is operating without permission. However, if the starter is driven only while the operation unit is being operated in order to eliminate such discomfort, the operability for starting the engine is reduced.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an engine start control device capable of starting an engine without discomfort while maintaining operability for starting the engine. Is to do.

[0007]

According to the first aspect of the present invention, there is provided an automatic engine starting apparatus for automatically driving a starter motor to start an engine by temporarily operating an operation unit. In the engine start control device that performs control, when the operation unit is operated at a point in time when a predetermined time has elapsed from the start of driving of the starter motor, manual engine start control that stops driving of the starter motor with the end of operation of the operation unit. The main point is to perform

According to a second aspect of the present invention, in the engine start control device according to the first aspect, when a predetermined time has elapsed since the engine was started, even if the operation section is operated, The gist of the present invention is to stop driving the starter motor.

According to a third aspect of the present invention, in the engine start control device according to the first or second aspect, the engine start after the manual engine start control fails the engine start by the automatic engine start control. The gist is that it can be performed only at the time of operation.

Hereinafter, the "action" of the present invention will be described. According to the first aspect of the invention, when the operation unit is operated at a point in time when a predetermined time has elapsed from the start of driving of the starter motor, the driving of the starter motor is stopped when the operation of the operation unit ends. . That is, the starter motor is driven and stopped by manual operation. Generally, when the operation unit is operated after a predetermined time has elapsed from the start of driving of the starter motor, it is considered that the operator has a desire to drive the starter motor by manual operation. For this reason, it is possible to start the engine reflecting the intention of the operator. In addition, when the operation unit is not operated after a predetermined time has elapsed from the start of driving of the starter motor, automatic engine start control is performed. Therefore, the operability for starting the engine is also maintained.

According to the second aspect of the invention, it is possible to prevent the starter motor from being driven more than necessary. This prevents an inconvenience that an overload is applied to the starter motor and the durability of the starter motor is deteriorated.

According to the third aspect of the present invention, manual engine start control is not performed at the first engine start. That is, at the time of the first engine start, only the automatic engine start control is performed. Usually, when the engine is relatively easy to start (such as when the oil temperature and the air temperature are not too low), the engine is reliably started by the automatic engine start control. On the other hand, in the manual engine start control, there are cases where the engine cannot be started even if the engine is relatively easily started. Therefore, the startability of the engine is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to FIGS. As shown in FIG. 1, the engine start control device 1 includes a portable device 11 owned by the owner (driver) of the vehicle 2 and a communication control device 21 mounted on the vehicle 2.

The portable device 11 includes a receiving circuit 12, a transmitting circuit 1,
3 and a microcomputer (microcomputer) 14. An antenna 15 is connected to the receiving circuit 12, and an antenna 16 is connected to the transmitting circuit 13.

The receiving circuit 12 receives the request signal output from the communication control device 21 via the antenna 15, demodulates the signal into a pulse signal, and inputs the pulse signal to the microcomputer 14. When the request signal is input, the microcomputer 14 outputs a transmission signal (ID code signal) including a preset predetermined ID code. The transmission circuit 13 converts the ID code signal to a predetermined frequency (300 in this embodiment).
(MHz), and transmits the radio signal to the outside via the antenna 16.

On the other hand, the communication control device 21
2, a receiving circuit 23 and a microcomputer 24 as a holding time control means. The microcomputer 24 includes a start switch 31, an alternator 3
2. Crank angle sensor 33 and starter motor driving device 34
Is connected. The start switch 31 is a switch provided near the driver's seat in the room of the vehicle 2,
In the present embodiment, it is constituted by a momentary push button switch provided on the instrument panel. The starter motor driving device 34 is connected to the starter motor 35 and, when a drive signal is input, drives the starter motor 35 to perform cranking.

The transmission circuit 22 and the reception circuit 23 are connected to a microcomputer 24, respectively. And the transmission circuit 2
An antenna 25 is connected to 2, and an antenna 26 is connected to the receiving circuit 23.

The transmission circuit 22 converts a request signal output from the microcomputer 24 to a predetermined frequency (in this embodiment, 13
4 kHz), and outputs the request signal via the antenna 25. The request signal is output to an area including the driver's seat in the room of the vehicle 2. Therefore, mutual communication between the portable device 11 and the communication control device 21 becomes possible in this output area.

The receiving circuit 23 can receive the ID code signal output from the portable device 11 via the antenna 26. The receiving circuit 23 demodulates the received ID code signal into a pulse signal to generate a received signal, and outputs the received signal to the microcomputer 24.

The microcomputer 24 has a C (not shown).
This is a CPU unit including a PU, a ROM, a RAM, and the like, and includes a nonvolatile memory 24a. In this memory 24a, a preset ID code is recorded. This ID code is set corresponding to the ID code set in the microcomputer 14 of the portable device 11. The microcomputer 24 outputs the request signal intermittently and, when the received signal is input, compares its own ID code with the ID code included in the received signal. When the ID codes match, the I
If the D code is included in the ID code signal transmitted in response to the request signal, the engine can be started. Then, in this engine start standby state, when the start switch 31 is operated (pressed), the starter motor driving device 34 is activated.
And outputs a drive signal to the device. As a result, the starter 35 is driven to start the engine.

The microcomputer 24 stops outputting a drive signal to the starter motor driving device 34 when a predetermined time (holding time T shown in FIG. 4) has elapsed since the start of the engine. In this embodiment, the microcomputer 24 sets the time when the output signal from the alternator 32 becomes H level as the engine start time, and stops the output of the drive signal when a predetermined time T has elapsed from this time.
That is, in the microcomputer 24, the holding time T for holding the output of the drive signal even after the engine is started is set. In this embodiment, the holding time T is 0.2 to 0.6.
Set to seconds.

Further, as shown in FIG.
Is set to a drivable time Tmx. Then, when the drivable time Tmx has elapsed, the microcomputer 24 stops outputting the drive signal even if the engine has not been started.

Next, detailed processing of the engine start control performed by the microcomputer 24 will be described with reference to the flowcharts shown in FIGS. This process is repeatedly executed at predetermined time intervals based on a program stored in the ROM constituting the microcomputer 24. Also,
The program may be recorded on a computer-readable recording medium other than the ROM.

First, in step S1, the microcomputer 24
Outputs a request signal to the transmission circuit 22.
Thereby, the request signal is output to a region including the driver's seat in the room of the vehicle 2.

In the following step S2, the microcomputer 24
Determines whether an ID code signal has been received from the portable device 11. If the microcomputer 24 has received the ID code signal, the process proceeds to step S3. If the microcomputer 24 has not received the ID code signal, the process here ends once.

In step S3, the microcomputer 24
The ID code included in the D code signal is compared with its own ID code.
If the ID codes do not match, the process here is temporarily terminated.

In step S4, the microcomputer 24 enters an engine start permission state. For details,
When the start switch 31 is operated in this state, a drive signal is output to the starter motor driving device 34. In other words, the microcomputer 24 operates the start switch 3 when the engine start is not permitted.
No drive signal is output even if 1 is operated.

In the following step S5, the microcomputer 24
Determines whether the start switch 31 has been pressed (whether the switch has been turned ON). Then, when the start switch 31 is turned on, the microcomputer 24 proceeds to the process of step S6, and when the start switch 31 is not turned on, the process here ends once.

In step S6, the microcomputer 24 outputs a drive signal to the starter motor driving device 34 to drive the starter motor 35. In the subsequent step S7, the microcomputer 24 outputs the drive signal, and then sets the automatic limited time Ta.
Is determined. And the microcomputer 24
Moves to the process of step S8 when the automatic limited time Ta has elapsed. In the present embodiment, the automatic limited time Ta is set to 0.5 seconds.

In step S8, the microcomputer 24 determines whether the value of the engine stall count C is "1" or more.
If the value of the engine stall count C is “1” or more, the microcomputer 24 proceeds to the process of step S9. The stalled count C indicates the number of times the engine stall has occurred.

In step S9, the microcomputer 24 determines whether or not the start switch 31 is on. That is, the microcomputer 24 determines whether or not the start switch 31 has been pressed when the automatic limited time Ta has elapsed. Usually, when the engine is to be started automatically, the start switch 31 is temporarily (momentarily) pressed. Therefore, the start switch 31 is not pressed after the automatic limited time Ta has elapsed. On the other hand, when the engine is to be started by manual operation, the start switch 31 is continuously pressed to drive the starter motor 35.
Therefore, the start switch 31 is kept pressed even after the automatic limited time Ta has elapsed. Therefore, by such processing, the microcomputer 24 can determine whether or not the operator intends to start the engine by manual operation. When the start switch 31 has been pressed, the microcomputer 24 proceeds to the process of step S10.

In step S10, the microcomputer 24
When the start switch 31 is turned off or when the holding time T has elapsed, the starter driving device 34
Then, the output of the drive signal corresponding to is stopped, and the process proceeds to step S12. That is, here, the driving of the starter motor 35 is stopped when the operation of the start switch 31 by the operator is completed. In other words, a manual engine start based on the operation of the operator is possible.
Further, the microcomputer 24 stops outputting the drive signal to the starter motor driving device 34 even when the holding time T has elapsed. That is, the microcomputer 24 stops outputting the drive signal when the holding time T has elapsed even if the start switch 31 is operated.

The microcomputer 24 determines in step S8
When the value of the engine stall count C is less than "1",
That is, when the value of the engine stall count C is "0", the process proceeds to the process of step S11. That is, the microcomputer 24
Performs the processing of step S11 at the time of the first engine start operation. Also, the microcomputer 24
Even when the start switch 31 is in the OFF state in step S9, the process proceeds to step S11. Then, in step S11, the microcomputer 24 stops outputting the drive signal to the starter motor driving device 34 after the elapse of the holding time T, and shifts to the process of step S12. That is, in the present embodiment, the microcomputer 24 cannot perform the manual engine start at the time of the first engine start.

In step S12, the microcomputer 24
It is determined whether engine stall has occurred. And
When the engine stall occurs, the microcomputer 24 proceeds to the process of step S13, adds “1” to the value of the engine stall count C, and proceeds to the process of step S14. In step S14, the microcomputer 24 determines in step S3
A predetermined time Tx after each ID code matches
It is determined whether or not has elapsed. And the microcomputer 24
If the predetermined time Tx has not elapsed, step S
The process shifts to the process of No. 4, and if the predetermined time Tx has elapsed, the process here is temporarily ended.

If no engine stall has occurred in step S12, the microcomputer 24 proceeds to step S15, sets the value of the engine stall count C to "0", and terminates the process here.

Next, the microcomputer 24 based on such processing
Will be described with reference to a time chart shown in FIG. Note that this time chart shows an operation mode in a state where the engine is difficult to start.

First, the microcomputer 24 determines the point P in FIG.
When the start switch 31 is operated in the engine start permission state as shown by 1, a drive signal is output to the starter motor driving device 34. Thus, the cell motor 35 is driven to perform cranking. And point P2
When the output signal from the alternator 32 goes to the H level as shown by, the microcomputer 24 stops outputting the drive signal when the holding time T has elapsed from that point, as shown by a point P3. That is, between the point P1 and the point P3, an automatic engine start control is performed in which the start switch 31 is momentarily turned on to perform an engine start operation. Therefore, the engine can be started by a one-touch operation.

Normally, when the engine is started by such an engine starting operation, the output signal from the alternator 32 maintains the H level. However, if an engine stall occurs after the output of the drive signal to the starter motor drive device 34 is stopped, the alternator 3
The output signal from 2 goes low.

In this case, when the start switch 31 is operated again as indicated by a point P5, the microcomputer 2
4 outputs a driving signal to the starter driving device 34 again. Then, as shown by a point P6, when the auto limited time Ta has elapsed, the start switch 31
When in the N state, the microcomputer 24 determines that the operator intends to start the engine by manual operation. Therefore, when the start switch 31 is turned off at a point P8 at which a predetermined time ΔT1 has elapsed since the output signal from the alternator 32 became H level as indicated by a point P7, the microcomputer 24 stops outputting the drive signal. I do. That is, even if the holding time T has not elapsed from the point P7,
Stop the output of the drive signal. Therefore, this point P5
From the point P8 to the point P8, the engine start control by the manual operation of the operator is performed.

However, as indicated by point P9, if engine stall occurs even by such a second engine start operation, it is necessary to perform a third engine start operation. In such a case, when the start switch 31 is operated again as indicated by the point P10, the microcomputer 24
Outputs a drive signal to the starter motor driving device 34 again. Then, the start switch 31 is turned on when the automatic limited time Ta has elapsed as shown by a point P11.
In this state, the microcomputer 24 determines that the operator is about to start the engine by manual operation. In this third engine start operation,
As indicated by a point P12, at a point indicated by a point P14 at which a predetermined time ΔT2 has elapsed since the output signal from the alternator 32 became H level, the start switch 31
It is in the FF state. Therefore, the microcomputer 24 should stop outputting the drive signal when the start switch 31 is turned off. However, “ΔT2
> T ”, the microcomputer 24 stops outputting the drive signal at the point P13 at which the holding time T has elapsed. That is, the microcomputer 24 prevents the driving of the starter motor 35 more than necessary even during manual engine start control.

Therefore, according to the present embodiment, the following effects can be obtained. (1) When the start switch 31 is operated when the automatic limited time Ta has elapsed since the start of driving of the cell motor 35, it can be determined that the operator has a desire to drive the cell motor by manual operation. In such a case, the engine start control device 1 drives the starter motor 35 only while the start switch 31 is being operated. That is, the starter motor 35 is driven by a manual operation. For this reason, it is possible to start the engine reflecting the intention of the operator. Therefore, the engine can be started without discomfort. In addition, when the start switch 31 is not operated when the automatic limited time Ta has elapsed since the start of the driving of the starter motor 35, the automatic engine start control is performed. Therefore, the convenience for starting the engine is also maintained.

(2) Holding time T after starting the engine
, The driving of the starter motor 35 is stopped even if the start switch 31 is operated. Therefore, even if the start switch 31 is pressed for a long time, it is possible to prevent the starter motor 35 from being driven more than necessary. Therefore, it is possible to prevent the disadvantage that the overload is applied to the starter motor 35 and the durability of the starter motor 35 is deteriorated.

(3) At the time of the first engine start, manual engine start control cannot be performed. That is, automatic engine start control is always performed at the time of the first engine start. Normally, when the engine is in a standard state (such as a state where the oil temperature and the air temperature are not too low), the engine is reliably started by the automatic engine start control. On the other hand, in the manual engine start control, there is a possibility that the engine cannot be started even if the engine is in a standard state. Therefore,
By performing the automatic engine start control at the time of the first engine start, the startability of the engine can be improved.

(4) The microcomputer 24 has a drivable time T
mx is set. Then, when the drivable time Tmx has elapsed, the microcomputer 24 stops outputting the drive signal even if the engine has not been started. Therefore, until the battery runs out, the cell motor 35
Can be reliably prevented from being driven.

The embodiment of the present invention may be modified as follows. In the above embodiment, manual engine start cannot be performed at the time of the first engine start. But,
The present invention is not limited to this, and a manual engine start may be enabled even at the first engine start.

In the above-described embodiment, even if the start switch 31 is kept pressed by the manual engine start operation, the drive of the starter motor 35 is stopped when the holding time T has elapsed after the start of the engine. . However, such a restriction may be canceled and the starter motor 35 may be driven during the manual engine start operation as long as the start switch 31 is kept pressed even after the holding time T has elapsed.

In the above embodiment, the holding time T is provided. However, the holding time T may be omitted. That is, when the automatic engine is started, the alternator 3
The driving of the starter motor 35 may be stopped at the same time as the output signal from the H level becomes H level.

In the above embodiment, the microcomputer 24
Sets the holding time T based on when the output signal from the alternator 32 goes high. However, the microcomputer 24 determines the holding time T based on when the output signal from the crank angle sensor 33 exceeds a predetermined threshold.
May be set.

In the above embodiment, the holding time T is
The same time is set for the automatic engine start control and the manual engine start control. However, the holding time T may be set to be different between the automatic engine start control and the manual engine start control. For example, the holding time T during manual control may be set longer than the holding time T during automatic control.

In the above embodiment, the holding time T is set in advance. That is, the holding time T is a fixed value in the embodiment. However, for example, as indicated by a two-dot chain line arrow in FIG.
4, the battery voltage, the air temperature, and the oil temperature may be input, and the holding time T may be set using these as parameters. Specifically, when the battery voltage drops, when the temperature is low,
When the oil temperature is low, the holding time T is set long, and when the battery voltage is normal, normal temperature, and when the oil temperature is high, the holding time T is set short. In particular, since the oil temperature remarkably reflects the state of the engine, by setting the holding time T based on the oil temperature, the optimum holding time T can always be set according to the state of the engine. Therefore, it is desirable that the oil temperature be the most important parameter, and that the holding time T be set longer as the oil temperature is lower and the holding time T be set shorter as the oil temperature is higher. Also,
The retention time T may be set using the time elapsed since the last stop of the engine or the number of past failures in starting as a parameter. This makes it possible to always set the optimal holding time T in accordance with the state of the engine, to further improve the startability of the engine, and to minimize the load applied to the starter motor 35. it can. In particular, by setting the oil temperature as the most important parameter, the startability of the engine and the durability of the starter motor 35 can be reliably improved.

In the above embodiment, the holding time T is set in advance. That is, the holding time T is a fixed value in the embodiment. However, the time from the start of driving of the starter motor 35 to the start of the engine (when the output signal from the alternator 32 becomes H level) may be measured, and the holding time T may be set based on the measured time. Normally, if the time from the start of driving the starter 35 to the start of the engine is long, the engine is in a state where it is difficult to start. Therefore, even in this case, the optimal holding time T can always be set according to the state of the engine, and the startability of the engine can be further improved.

In the above embodiment, the microcomputer 24
In the processing of step S5 in FIG. 2, when the start switch 31 is not turned on, the processing is temporarily ended. However, the microcomputer 24 sets the start switch 31 to ON in the process of step S5.
If not, the process may proceed to step S11.

In the above embodiment, the drivable time Tmx is set in the microcomputer 24. When the drivable time Tmx has elapsed since the output of the drive signal to the starter motor driving device 34, the microcomputer 24 stops the output of the drive signal even if the engine has not been started. However, this drivable time T
It is not necessary to provide mx. In addition, this drivable time Tmx
May be variable, for example, set to be short when the battery voltage drops.

In the above-described embodiment, the holding time T at the time of starting the engine for the second and subsequent times performed after the engine stall occurs.
And the holding time T at the time of the first engine start performed when the engine stall has not occurred is set to the same time. However, the holding time T at the time of the second and subsequent engine starts is T
May be set longer than the holding time at the time of the first engine start. For example, if the holding time T at the time of the first engine start is set to the minimum holding time at which the engine can be reliably started in the normal state of the engine (average oil temperature and air temperature state), the motor is added to the starter motor 35. The load decreases. Further, since the second and subsequent holding times T are set long, even if the first engine start fails, the engine can be started quickly by the second and subsequent engine starts. Therefore, the startability of the engine and the durability of the starter motor 35 are improved.

In the above embodiment, the engine start control device 1 includes the portable device 11 and the communication control device 21. Further, a push button switch is used as the start switch 31. And the communication control device 2
1 indicates that the I of the portable device 11
The engine is started when the start switch 31 is pressed in a state where the D code and the own ID code match. However, the portable device 11 may be omitted, and the communication control device 21 in which the transmission circuit 22, the reception circuit 23, and the antennas 25 and 26 are omitted may be used as the engine start control device 1. In such a case, if the start switch 31 is a conventional ignition switch, security can be ensured by disabling the engine start operation by anyone other than the machine key holder, and the engine start operation can be simplified. Moreover, the configuration of the engine start control device 1 can be simplified.

Next, in addition to the technical ideas described in the claims, technical ideas grasped by the above-described embodiments will be listed below.
