DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a vehicle equipped with an internal combustion engine started by a starter and a transmission.

[0002]

2. Description of the Related Art Generally, in a vehicle equipped with an internal combustion engine and a transmission, the internal combustion engine is started by driving a starter. In recent years, a starter holding function may be provided in order to reliably start the internal combustion engine. This starter holding function means that when the engine key is turned to the start position and the start switch is once turned on, the starter starts driving to start the internal combustion engine, and a period until the start of the internal combustion engine is completed. , So that the starter continues to be driven. In this starter holding function, after the start switch is once turned on, the engine key returns to the ignition position and the start switch is turned off.

[0003]

However, in a vehicle provided with the above-mentioned starter holding function, the relationship between the return of the engine key to the ignition position and the completion of the start of the internal combustion engine is poor. Therefore, it is difficult for the driver to recognize that the start of the internal combustion engine has been completed based on the return of the engine key to the ignition position. If the driver changes the shift position of the transmission while the start of the internal combustion engine is not completed, an excessive load is applied to the internal combustion engine via the transmission. At this time, since the engine speed has not reached a predetermined speed (for example, idle speed), there is a problem that the internal combustion engine is stalled.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a vehicle control device capable of reliably starting an internal combustion engine.

[0005]

The means for achieving the above object and the effects thereof will be described below. In a vehicle equipped with an internal combustion engine, a starter for starting the internal combustion engine, and a transmission, when the internal combustion engine is started by driving the starter,
The gist of the present invention is to provide a restricting means for prohibiting a change of a shift position of the transmission.

When the internal combustion engine is started, the engine speed does not reach the predetermined speed and is unstable. According to the first aspect of the present invention, the change of the shift position of the transmission is prohibited when the internal combustion engine is started, so that an excessive load is not applied to the internal combustion engine via the transmission. Stall of the internal combustion engine can be prevented, and the internal combustion engine can be started reliably.

According to a second aspect of the present invention, in the vehicle control apparatus according to the first aspect, the limiting means includes a shift lock mechanism for mechanically inhibiting a shift position of the transmission. And

According to the second aspect of the invention, when the internal combustion engine is started, the shift lock mechanism mechanically prohibits the shift position of the transmission from being changed. According to a third aspect of the present invention, in the vehicle control device according to the first aspect,
A shift operation mechanism that outputs an electric shift signal in response to a shift operation of an operation member that selects a shift position of the transmission, wherein the transmission changes a shift position based on a shift signal from the shift operation mechanism. An essential point is that the actuator includes a switching actuator, and the limiting means inhibits the operation of the actuator by disabling a shift signal of the shift operation mechanism, thereby inhibiting a change of a shift position of the transmission. .

According to the third aspect of the invention, when the internal combustion engine is started, the operation of the actuator is inhibited by disabling the shift signal of the shift operation mechanism, and the change of the shift position of the transmission is inhibited.

According to a fourth aspect of the present invention, in the vehicle control device according to any one of the first to third aspects, a determination means for determining whether or not the start of the internal combustion engine by driving the starter is completed; A starter holding unit that continues to drive the starter during a period from when the starter is started to when it is determined that the start of the internal combustion engine has been completed, wherein the limiting unit is configured to at least drive the starter. The gist is that the change of the shift position of the transmission is prohibited during a period from the start to the time when it is determined that the start of the internal combustion engine is completed.

According to the fourth aspect of the present invention, when the start of the starter is started at the start of the internal combustion engine, the starter is continuously driven by the starter holding means until the start of the internal combustion engine is completed. . While the starter is driving, the engine rotation speed has not reached the predetermined rotation speed and the engine rotation speed is unstable, but at least during the starter driving, the change of the shift position of the transmission is prohibited. Therefore, an excessive load is not applied to the internal combustion engine via the transmission, and the internal combustion engine can be stably started by preventing the internal combustion engine from being stalled.

According to a fifth aspect of the present invention, in the vehicle control device according to the fourth aspect, the determination means completes the start of the internal combustion engine based on the fact that the engine speed has become equal to or higher than a predetermined speed. The gist is that the judgment is made.

According to the fifth aspect of the present invention, the autonomous operation of the internal combustion engine becomes possible if the engine speed becomes equal to or higher than the predetermined speed at the time of starting the internal combustion engine. Can be determined.

According to a sixth aspect of the present invention, in the vehicle control device according to the fourth aspect, the determining means determines that the first predetermined time has elapsed from the start of driving of the starter. The gist is to judge that the start of the internal combustion engine has been completed.

According to the sixth aspect of the invention, if the starter is driven for the first predetermined time when the internal combustion engine is started, the engine speed becomes higher than the predetermined speed and the internal combustion engine can operate autonomously. Therefore, it can be determined that the start of the internal combustion engine has been completed.

However, at the time of normal cold start of the internal combustion engine, the warm-up is not completed, and immediately after the starter is stopped, the engine speed is not increased. It is stable. In this regard, according to the invention described in claim 7, it is determined that the start of the internal combustion engine has been completed, and further, the change of the shift position of the transmission is prohibited until the second predetermined time elapses. . for that reason,
Even during normal cold start of the internal combustion engine, the internal combustion engine can be reliably started by preventing stall of the internal combustion engine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) A first embodiment of the present invention will be described below in detail with reference to FIGS.

FIG. 1 is a schematic configuration diagram showing a vehicle equipped with an internal combustion engine and a transmission according to this embodiment. Here, a gasoline engine (hereinafter, referred to as “engine”) 2 is used as an internal combustion engine. The engine 2 is mounted on a vehicle for driving an automobile.

The engine 2 is started by driving a starter 4. An output shaft (not shown) of the engine 2 is connected to the torque converter 6. The torque converter 6 converts the input rotation into fluid (oil).
And transmits the inputted rotation to an automatic transmission (hereinafter, referred to as “A / T”) 8. A / T8 changes the speed of the input rotation to output shaft 1
Output to the 0 side and finally transmit to the wheels.

The hydraulic control unit 12 of the A / T 8 is provided with a shift position switching motor 14 as an actuator. The output shaft of the motor 14 is connected to a manual valve (not shown) for switching the supply destination of the control oil pressure. When the motor 14 is rotationally driven, the position of the manual valve is switched, thereby changing the position of P (parking), R (reverse), N (neutral), D (drive), and the like.

A shift operating device 1 as a shift operating mechanism for selecting the shift position of the A / T 8 is installed in the vehicle interior.
6 are provided. A plurality of shift positions P, R, N, D, 2 (second speed), L (1
Speed) is set. The shift operating device 16 includes a shift lever 18 that can be tilted and operated in the direction of the arrow between these shift positions. The shift operation device 16 detects a shift operation of the shift lever 18 by a shift detection sensor (not shown), and outputs an electric shift signal according to the shift operation.

In the vehicle according to the present embodiment, an engine ECU that mainly controls the engine 2 and the starter 4
(“E / GECU”) 20 and a transmission ECU (“A / TECU”) that mainly controls the A / T 8 and the motor 14
30. The ECUs 20 and 30 are electrically connected through an in-vehicle network line.

The detection signal of the rotation speed sensor 24 for detecting the rotation speed NE of the engine 2 is input to the E / GE ECU 20. Further, the E / GE ECU 20 receives detection signals from an idle switch, an accelerator opening sensor, a throttle opening sensor, a shift position sensor, a brake switch, a water temperature sensor, and other sensors (not shown). The idle switch detects whether the accelerator pedal is depressed, and the accelerator opening sensor detects the amount of depression of the accelerator pedal (accelerator opening).
The throttle opening sensor detects the opening of a throttle valve for adjusting the intake air amount of the engine 2, and the shift position sensor detects the shift position of the A / T8. The brake switch detects the depression of the brake pedal, and the water temperature sensor detects the temperature of the engine cooling water.

The E / GECU 20 includes an engine 2
Switch 2 to enable continuous operation of
6. Start switch 2 for starting the engine 2
8 is input.

The E / GECU 20 is mainly composed of a microcomputer. The E / GE ECU 20 executes necessary arithmetic processing based on a detection signal from each sensor and an operation signal of each switch according to a program written in an internal ROM. The E / GE ECU 20 performs fuel injection control for driving a fuel injection valve for injecting fuel into the engine 2 and ignition timing control for driving an igniter based on the calculation result, and appropriately controls the operating state of the engine 2. .

When the engine 2 is started, E /
GECU 20 functions as starter holding means. That is, once the driver turns the engine key to the start position and once turns on the start switch 28, the E / GE ECU 20 starts driving the starter 4 and completes the starter 4 operation until the start of the engine 2 is completed. , The engine 2 is started. At the time of this start, the E / GE ECU 20 functions as a determination unit, and based on the detection signal of the rotation speed sensor 24, when the rotation speed NE of the engine 2 becomes equal to or higher than a predetermined rotation speed (for example, an idle rotation speed), It is determined that the start has been completed. The start switch 28 can be turned on only when the shift position of the A / T 8 is set to the P position or the N position. Further, once the start switch 28 is turned on, the engine key is returned to the ignition position and the start switch is turned off.

Further, the E / GE ECU 20 includes a timer 22. When it is determined that the start of the engine 2 is completed, the E / GE ECU 20 starts the timer 22 and measures a predetermined time TAS. The shift signal of the shift operation device 16 is input to the A / TECU 30. The A / TECU 30 is mainly configured by a microcomputer. A / T
When the engine 2 is in a normal operation state, the ECU 30 executes necessary arithmetic processing based on a shift signal of the shift operation device 16, a vehicle running speed, an engine load, and the like, according to a program written in an internal ROM. A
/ TECU 30 determines the motor 14 based on the calculation result.
To shift the A / T 8 shift position, and to move forward (D, 2, L).
The automatic switching of each speed stage in is executed.

When the engine 2 is started, A /
The TECU 30 functions as a restricting unit that prohibits the change of the shift position of the A / T 8. That is, the starter 4
During the driving of the motor and during a period until the predetermined time TAS elapses after the starter 4 is stopped, the operation of the motor 14 is prohibited by disabling the shift signal of the shift operating device 16 and the A / T
Change of the shift position is prohibited. As described above, when the change of the shift position of the A / T 8 is prohibited at the time of starting the engine 2, an excessive load is not applied to the engine 2 via the A / T 8, and the stall of the engine 2 is prevented, so that the engine 2 is stably prevented. It starts to work.

Next, control processing executed by the E / GE ECU 20 and the A / TECU 30 when the engine 2 is started will be described with reference to the flowchart of FIG. This process is a process that is periodically and repeatedly executed every preset short time. Prior to this processing, the engine key is operated to the ignition position, and the ignition switch 26 is turned on.

When this processing is started, first, in step 1
At 02, it is determined whether the start switch 28 is ON. If it is determined that the start switch 28 is ON, the process proceeds to step 104, where the start switch 2
If it is determined that 8 is OFF, the process proceeds to step 120. In step 120, it is determined whether or not the starter drive flag is ON. If the determination is affirmative, the process proceeds to step 106, and if the determination is negative, the process proceeds to step 116.

In step 104, ON is set as a starter drive flag for driving the starter 4, and in step 106, the starter 4 is driven, and the engine 2 is cranked. As long as the starter drive flag is set to ON, the starter 4 continues to be driven.

In step 108 following step 106, it is determined whether or not the start of the engine 2 has been completed based on whether or not the engine speed NE is equal to or higher than a predetermined speed N0. For example, an idle rotation speed can be set as the predetermined rotation speed N0. If it is determined that the engine rotation speed NE is lower than the predetermined rotation speed N0, that is, the start of the engine 2 is not completed, step 110 is executed.
Proceed to. If it is determined that the engine rotation speed NE is equal to or higher than the predetermined rotation speed N0, that is, it is determined that the start of the engine 2 has been completed, the process proceeds to step 112.

In step 110, ON is set as a shift change prohibition request flag for prohibiting the change of the shift position of the A / T 8, and this routine is ended once.
At this time, even if a shift signal to the reverse travel position (R) or the forward travel position (D, 2, L) is input based on the shift operation of the shift operation device 16, the shift state is prohibited based on the shift change prohibition request flag in the ON state. The shift signal is invalidated. Accordingly, in a state where the start of the engine 2 is not completed, the driving of the motor 14 is prohibited, and the change of the shift position of the A / T 8 is prohibited.

In step 112, since the start of the engine 2 is completed, the starter driving flag is set to OFF, and in the following step 114, the starter 4 is stopped. When the starter 4 is stopped, that is, when the engine 2
Is completed, the timer 22 is started, and the timer 22 starts counting time.

In the next step 116, the starter 4
It is determined whether or not a predetermined time TAS has elapsed after the stop of the operation. The predetermined time TAS is a period provided for determining whether or not the engine speed NE has stabilized after the starter 4 has stopped. The predetermined time TAS can be set to an arbitrary value. If an affirmative determination is made in step 116, the process proceeds to step 118, and if a negative determination is made, the present routine is temporarily ended.

At step 118, OFF is set as the shift change prohibition request flag. At this time, based on the shift operation of the shift operation device 16, the reverse traveling position (R) or the forward traveling position (D, 2,
When the shift signal to L) is input, the shift signal is valid since the shift change prohibition request flag is OFF. That is, since the start of the engine 2 has been completed and the engine rotational speed NE has been stabilized, the motor 14 is driven based on the shift signal, and the shift position of the A / T 8 is changed.

According to the above-described embodiment, the following effects can be obtained. (1) When the engine 2 is started, the engine rotational speed NE does not reach the predetermined rotational speed and is unstable. At this time, the change of the shift position of the A / T 8 is prohibited. Therefore, an excessive load is not applied to the engine 2 via the A / T 8, and the engine 2 can be prevented from being stalled and the engine 2 can be reliably started.

(2) In this embodiment, the shift operation device 1
6 outputs an electric shift signal according to the shift operation,
The A / T 8 has a motor 14 for switching a shift position based on a shift signal. When the engine 2 is started, the shift signal of the shift operation device 16 is invalidated to prohibit the driving of the motor 14 and the A / T 8
Can be prohibited, and the engine 2 can be reliably started.

(3) When the engine 2 is started, the autonomous operation of the engine 2 is enabled if the start of the engine 2 is completed. However, the warm-up is not completed at the time of the normal cold start of the engine 2, and the starter is not started. Immediately after the stop of No. 4, the engine rotation speed NE is unstable. When the engine 2 starts, A
/ TECU 30 determines that A is longer than a predetermined time TAS after the start of engine 2 is determined to be completed.
The change of the / T8 shift position is prohibited. Therefore, even during the normal cold start of the engine 2, it is possible to prevent the stall of the engine 2 and start the engine 2 reliably.

(4) In a vehicle equipped with an automatic transmission, no clutch mechanism operated by the driver is provided between the engine 2 and the A / T 8. Therefore, if the shift position of the A / T 8 is changed when the engine 2 is started, the engine 2 and the A / T 8 are connected, and an excessive load is applied to the engine 2 and the engine 2 is stalled. Therefore, especially in a vehicle equipped with an automatic transmission, prohibiting a change in the shift position of the A / T 8 when the engine 2 is started is useful for surely starting the engine 2.

Is connected to a manual valve (not shown) for switching the supply destination of the control hydraulic pressure. When the outer lever 32 is driven to rotate, the position of the manual valve is switched to change the position of P (parking), R (reverse), N (neutral), D (drive), and the like. The hydraulic control unit 12 is provided with a shift lock mechanism 34. The shift lock mechanism 34 prevents the change of the shift position of the A / T 8 by preventing the rotation of the outer lever 32.

A shift operation device 36 as a shift operation mechanism for performing a shift operation of the A / T 8 is provided in the vehicle interior.

Further, the E / GECU 20 includes another timer 42 in addition to the timer 22, and when the engine 2 is started, the E / GECU 20 functions as a starter holding unit and a determination unit. That is, once the driver turns the engine key to the start position and once turns on the start switch 28, the E / GE ECU 20 starts driving the starter 4 and completes the starter 4 operation until the start of the engine 2 is completed. , The engine 2 is started. At the time of this start, the E / GECU 2
0 functions as a determination unit. That is, based on the start of driving of the starter 4, that is, the timer 42 is started based on the ON operation of the start switch 28 to start time measurement, and when a predetermined time TDS is measured, it is determined that the start of the engine 2 is completed. This is because if the starter 4 continues to be driven for a predetermined time TDS when the engine 2 is started, the engine speed NE becomes equal to or higher than the predetermined speed N0, the autonomous operation of the engine 2 becomes possible, and the start of the engine 2 is completed. Because it can be determined that

In this embodiment, the A / TECU 30
Performs necessary arithmetic processing according to a program written in an internal ROM based on a vehicle running speed, an engine load, and the like. The A / TECU 30 calculates the forward running position (D,
Automatic switching of each gear stage in (2, L) is executed.

When the engine 2 is started, A /
The TECU 30 functions as a restricting unit that prohibits the change of the shift position of the A / T 8. That is, the starter 4
During the driving of the starter 4 and during a period until the predetermined time TAS elapses after the starter 4 stops, the shift lock mechanism 34 is operated to prohibit the rotation of the outer lever 32 and prohibit the change of the shift position of the A / T 8. As described above, when the change of the shift position of the A / T 8 is prohibited at the time of starting the engine 2, an excessive load is not applied to the engine 2 via the A / T 8, and the stall of the engine 2 is prevented, so that the engine 2 is stably prevented. It starts to work.

In step 130 following step 106, it is determined whether the start of the engine 2 has been completed based on whether a predetermined time TDS has elapsed after the starter 4 has been driven. If the starter 4 continues to be driven by the TDS for a predetermined time, it can be determined that the engine rotation speed NE has become equal to or higher than the predetermined rotation speed N0 and the start of the engine 2 has been completed. Affirmatively determined in step 130,
That is, if it is determined that the start of the engine 2 has been completed, the process proceeds to step 112;
Proceed to.

In step 132, the shift lock mechanism 34
Is operated, and the rotation of the outer lever 32 is prohibited. Therefore, when the start of the engine 2 is not completed, the shift operation device 36 cannot perform the shift operation of the shift lever 38,

At step 112, since the start of the engine 2 is completed, the starter driving flag is set to OFF, and at step 114, the starter 4 is stopped. When the starter 4 is stopped, that is, when the engine 2
Is completed, the timer 22 is started, and the timer 22 starts counting time.

At step 116, it is determined whether or not a predetermined time TAS has elapsed after the starter 4 has stopped. If the determination is affirmative, the process proceeds to step 134. If the determination is negative, the routine is temporarily terminated.

In step 134, the operation of the shift lock mechanism 34 is released, and the rotation of the outer lever 32 is permitted. That is, since the start of the engine 2 is completed and the engine rotational speed NE is stabilized, the outer lever 32 is rotated by the shift operation device 36 based on the shift operation of the shift lever 38, and the shift position of the A / T 8 is changed. Will be executed.
