Abstract

PROBLEM TO BE SOLVED: To prevent the stop of an engine by inhibiting the operation of a shift lever at the time of the engine being started by a remote controller in a device for inhibiting or authorizing the operation of the shift lever by electrical control. SOLUTION: Upon receiving an engine start operation signal from a remote controller 3 by a receiving circuit 2, a control device 1 starts an engine through an engine starting circuit 4, and identifies that this is started by the remote controller 3 and switches a parking position detection signal, inputted from a shift position detecting switch 8, to a position detection signal other than parking. In this state, even if a foot brake detection signal is inputted from a foot brake switch 7, since a parking position detection signal is not inputted, the control device 1 does not output an operation authorization signal to a shift lock ECU 9, so that shift lock mechanism is not released.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle equipment control device having a function of prohibiting or permitting operation of a shift lever in starting an engine by remote control means.

[0002]

Conventionally, there has been provided a device capable of starting an engine of a vehicle in a stopped state by an operation signal transmitted from a portable remote controller. That is, this type of vehicle engine start control device has a predetermined engine start condition (for example, the shift lever is not in the traveling position and the parking brake is operated) when the operation signal from the remote controller is received. That is, the engine start control is performed on the premise that the conditions (such as that the engine has not been started) are satisfied. In a stopped vehicle, the steering operation is not permitted only by starting the engine with a remote controller for reasons such as prevention of theft. In this case, steering operation is not allowed. To permit, the steering lock is generally released by operating the ignition key.

On the other hand, as a structure for improving the safety of the vehicle,
Some electrically control or prohibit the operation of the shift lever. This one prohibits the operation of the shift lever after that when the shift lever is operated to the parking position, and permits the operation of the shift lever when the engine is operating and the foot brake is depressed. Is configured.

When the engine is started by the remote controller and the foot brake is depressed without operating the ignition key, the steering lock is not released and the operation of the shift lever is permitted. Will be satisfied. Therefore, in this state, if the shift lever is operated from the parking position to the traveling position, the vehicle will be in a traveling impossible state. Therefore, in the above configuration, in such a case (when the engine is started by the remote controller and the shift lever is operated before operating the ignition key), the engine is not operated when the shift lever is operated from the parking position. Is forcibly stopped, which prevents the vehicle from falling into a state in which the vehicle cannot run.

However, in the above case, in order for the user to drive the vehicle, the engine must be started again by the ignition key, even though the engine is once started by the remote controller. However, there was a problem that the effort was troublesome.

The present invention has been made in view of the above circumstances, and an object thereof is to prohibit or permit the operation of a shift lever by electrical control, and when the engine is started by a remote controller, the shift is performed. It is an object of the present invention to provide a vehicle equipment control device that prohibits the operation of the lever and thereby prevents the engine from stopping due to the operation of the shift lever.

[0007]

In order to achieve the above-mentioned object, the vehicle equipment control device of the present invention comprises a remote control means for transmitting an engine start operation signal, and a remote control means or an ignition key. Engine start control means for starting the engine, shift position detection means for outputting a parking position detection signal when the shift lever is in the parking position, and brake detection means for outputting a brake detection signal when the brake is applied. And shift lock means for permitting the operation of the shift lever when the operation permission signal is given,
When the engine is started by the remote operation means, the output of the operation permission signal is prohibited regardless of the detection state of the shift position detection means, the steering lock is released by the operation of the ignition key, and then the shift position detection means. And a shift lock release control means for outputting an operation permission signal when the parking position detection signal is output by the brake detection signal and the brake detection signal is output by the brake detection means.

In the vehicle equipment control device having the above-described structure, when the engine is started by the remote operation means, the operation permission signal from the shift lock release control means to the shift lock means is irrespective of the detection state of the shift position detection means. Is not given, the operation of the shift lever is prohibited.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION A first embodiment of the present invention will now be described with reference to FIG.
It will be described with reference to FIGS. In FIG. 1 showing an electrical configuration, a control device 1 has both engine start control means and shift lock releasing means according to the present invention, and is connected from a power supply terminal + B of a vehicle battery via a power supply circuit (not shown). Power is being supplied. When the receiving circuit 2 receives the engine start operation signal from the remote operation device 3 which is the remote operation means, the control device 1 causes the engine start circuit 4 to start the engine.

The ignition switch 5 is in the off position,
It can be switched to 4 stages of accessory position, ON position and start position, and depending on the operating position, the accessory circuit,
It is connected so as to form 1 to 3 circuits of the ignition circuit and the engine starter circuit via the power supply terminal + B. The ignition switch 5 is integrated with a steering lock mechanism. When the ignition key is inserted into the rotor of the key cylinder and turned to the accessory position, the steering operation is permitted, and the ignition switch is turned to the off position to turn the ignition key. The steering operation is prohibited when it is removed from the rotor.

The key remind switch 6 is for detecting whether or not the ignition key is inserted into the rotor, and outputs a key remind signal in the inserted state. Therefore, the control device 1 causes the engine starting circuit 4 to start the engine when the key reminding signal is input from the key reminding switch 6 and the start position detection signal is input from the ignition switch 5.

The foot brake switch 7 outputs a foot brake detection signal when detecting that the foot brake is depressed. The shift position detection switch 8 detects the position of the shift lever and outputs a parking position detection signal when it is the parking position.

Further, a shift lock ECU 9 as a shift lock means is connected to the control device 1, and this shift lock ECU 9 is also supplied with power from a power supply terminal + B of an on-vehicle battery as in the control device 1. Shift lock ECU
9 inputs an operation permission signal output from the control device 1 when the control device 1 inputs both the foot brake detection signal and the parking position detection signal.
Then, the shift lock ECU 9 energizes the shift lock solenoid 10 when the operation permission signal is input, and the shift lock solenoid 10 permits the operation of the shift lever in the energized state (releases the shift lock mechanism).
However, the operation of the shift lever is prohibited (the shift lock mechanism is locked) in the non-energized state.

Next, the operation of the above configuration will be described. First, a case where the user starts the engine by operating the ignition key will be described with reference to the time chart of FIG. When the vehicle is stopped, that is, when the shift lever is in the parking position and the steering lock is locked, when the user inserts the ignition key into the rotor and turns the ignition key from the off position, first, The steering lock is released at the accessory position. Further, when the ignition key is turned to the start position, the control device 1 inputs the key remind signal from the key remind switch 6 and the start position detection signal from the ignition switch 5, so that the engine start circuit 4 operates. Start the engine (this timing is indicated by t1 in Fig. 2).

Thereafter, when the foot brake is depressed, the foot brake switch 7 outputs a foot brake detection signal. At this time, the control device 1 is inputting the parking position detection signal from the shift position detection switch 8, so the output condition of the operation permission signal (the foot brake detection signal is input from the foot brake switch 7 and the shift position is detected) It is determined that the condition for inputting the parking position detection signal from the detection switch 8 is satisfied, and an operation permission signal is output to the shift lock ECU 9. When the shift lock ECU 9 inputs the operation permission signal, the shift lock solenoid 10
Energize to release the shift lock mechanism (this timing is indicated by t2 in Fig. 2).

When the stepping operation of the foot brake is stopped, the foot brake switch 7 stops outputting the foot brake detection signal, the control device 1 judges that the output condition of the operation permission signal is not satisfied, and the shift lock ECU
The output of the operation permission signal to 9 is stopped. Accordingly
The shift lock ECU 9 includes a shift lock solenoid 10
To turn off the power and lock the shift lock mechanism (this timing is indicated by t3 in Fig. 2).

On the other hand, the case where the engine is started by the remote controller 3 will be described with reference to the time chart of FIG. When the vehicle is stopped, the user uses the remote controller 3 to send an operation signal for starting the engine to the control device 1.
When the receiving circuit 2 receives the operation signal in response to this, the control device 1 starts the engine by the engine starting circuit 4 and identifies that it is started by the remote controller 3. Then, the parking position detection signal input from the shift position detection switch 8 is switched to a position detection signal other than parking. (This timing is indicated by t1 in Fig. 3).

Thereafter, when the foot brake is depressed, the foot brake switch 7 outputs a foot brake detection signal (this timing is indicated by t2 in FIG. 3). At this time, the control device 1 determines that the parking position detection signal is not input from the shift position detection switch 8 (the position detection signal other than parking is input). It is determined that the signal output condition is not satisfied, and the operation permission signal is not output to the shift lock ECU 9. Therefore, the shift lock mechanism remains locked. In this case, to release the shift lock mechanism, the ignition key may be inserted into the rotor and rotated from the off position to the accessory position.

As described above, according to the above-described embodiment, the control device 1 receives the predetermined condition (the foot brake detection signal is input from the foot brake switch 7 and the shift is performed when the engine is started by the ignition key). On condition that the condition for inputting the parking position detection signal from the position detection switch 8 is satisfied, an operation permission signal is output to the shift lock ECU 9 to release the shift lock mechanism. On the other hand, when the engine is started by the remote controller 3, the control device 1 switches the parking position detection signal input from the shift position detection switch 8 to a position detection signal other than parking, so that the above-mentioned predetermined condition is satisfied. If not established, the operation permission signal is not output to the shift lock ECU 9 and the shift lock mechanism is not released. Therefore, when the engine is started by the remote controller 3, it is possible to prevent the shift lever from being operated and stop the engine from being stopped. Therefore, the operation of restarting the engine can be eliminated.

The present invention may be carried out as follows. When the engine is started by the remote controller 3, the control device 1 sets the other one of the predetermined conditions for outputting the above-mentioned operation permission signal, that is, the foot brake detection signal from the foot brake switch 7. , It is also possible not to input even though the foot brake is depressed.

FIG. 4 to FIG. 6 show a second embodiment of the present invention, and the portions different from the first embodiment will be described below. The control device 11 includes a relay 12 that connects and disconnects the power source of the shift lock ECU 9. This relay 12
One contact piece 13a of the relay switch 13 is connected to the power supply terminal + B of the vehicle battery via the ignition switch 5.
And the other contact piece 13b is connected to the shift lock circuit of the shift lock ECU 9. Then, the relay switch 13 is provided in the relay coil 1 when the ignition switch 5 detects the accessory position.
4 is driven to be turned on. That is,
The shift lock ECU 9 is energized at the same time that the steering lock is released when the user inserts the ignition key into the rotor and turns the ignition key from the off position to the accessory position.

In the second embodiment, first, the case where the user starts the engine by operating the ignition key will be described with reference to the time chart of FIG. When the user inserts the ignition key into the rotor and turns the ignition key while the vehicle is stopped, the steering lock is released at the accessory position and, at the same time, the relay coil 14 is driven to turn on the relay switch 13. The control device 1 energizes the shift lock ECU 9. Further, when the ignition key is rotated to the start position, the control device 11 inputs the key remind signal from the key remind switch 6 and the start position detection signal from the ignition switch 5, so that the engine start circuit 4 operates. Start the engine (this timing is indicated by t1 in Fig. 5).

Thereafter, when the foot brake is depressed, the foot brake switch 7 outputs a foot brake detection signal. At this time, since the control device 11 is inputting the parking position detection signal from the shift position detection switch 8, it is determined that the above output condition of the operation permission signal is satisfied, and the shift lock ECU
An operation permission signal is output to 9 to release the shift lock mechanism (this timing is indicated by t2 in FIG. 5).

When the stepping operation of the foot brake is stopped, the foot brake switch 7 stops the output of the foot brake detection signal, and the control device 11 judges that the output condition of the operation permission signal is not satisfied, and the shift lock mechanism is set. Lock (this timing is indicated by t3 in Fig. 5).

On the other hand, the case where the engine is started by the remote controller 3 will be described with reference to the time chart of FIG. When the vehicle is stopped, the user uses the remote controller 3 to send an operation signal for starting the engine to the control device 1.
When the reception circuit 2 receives the operation signal in response to the transmission, the control device 11 causes the engine starting circuit 4 to start the engine. (This timing is t1 in Fig. 6.
).

Thereafter, when the foot brake is depressed, the foot brake switch 7 outputs a foot brake detection signal (this timing is shown by t2 in FIG. 6), and at this time, the control device 11 causes the shift position detection switch to operate. Since the parking position detection signal is inputted from 8, it is judged that the above output condition of the operation permission signal is satisfied, and the operation permission signal is output to the shift lock ECU 9, but the shift lock ECU 9 is disconnected. Since there is up to this, it is not driven and the shift lock mechanism remains locked. In this state, the shift lock mechanism can be released by inserting the ignition key into the rotor and rotating it from the off position to the accessory position.

The second embodiment as described above also has the same effect as that of the first embodiment. That is,
When the engine is started by operating the ignition key, the control device 11 energizes the shift lock ECU 9 prior to starting the engine, and supposes that a predetermined condition is satisfied after the engine is started. An operation permission signal is output to the shift lock ECU 9 to release the shift lock mechanism. On the other hand, when the engine is started by the remote controller 3, the shift lock ECU 9 is cut off to prevent the shift lock mechanism from being released. Therefore, when the engine is started by the remote controller 3, it is possible to prevent the operation of the shift lever from being stopped and to prevent the engine from stopping. Therefore, the operation of restarting the engine can be eliminated.

[0028]

As is apparent from the above description, according to the invention of claim 1, the shift lock releasing means is
When the engine is started by the ignition key, a predetermined condition (the shift position detecting means outputs the parking position detecting signal and the brake detecting means outputs the brake detecting signal) is satisfied. As a premise, an operation permission signal is output to the shift lock means to permit the operation of the shift lever.
On the other hand, when the engine is started by the remote control means, the operation of the shift lever is not permitted by not outputting the operation permission signal to the shift lock means regardless of the detection state of the shift position detection means. Therefore, when the engine is started by the remote operation means, the operation of the shift lever is prohibited, and it is possible to prevent the engine from stopping due to the operation of the shift lever, thus restarting the engine. It is possible to eliminate the action that causes it.

According to the second aspect of the present invention, the shift lock releasing means permits the shift lock means to operate when the engine is started by the ignition key on the assumption that the above-mentioned predetermined condition is satisfied. A signal is output to permit the shift lever operation. On the other hand, when the engine is started by the remote operation means, the operation of the shift lever is not permitted by not outputting the operation permission signal to the shift lock means regardless of the detection state of the brake detection means. Therefore, when the engine is started by the remote operation means, the operation of the shift lever is prohibited, and it is possible to prevent the engine from stopping due to the operation of the shift lever, thus restarting the engine. It is possible to eliminate the action that causes it.

According to the third aspect of the invention, the shift lock releasing means energizes the shift lock circuit when the engine is started by the ignition key on the assumption that the above predetermined condition is satisfied. At the same time, an operation permission signal is output to the shift lock circuit to permit the operation of the shift lever. On the other hand, when the engine is started by the remote control means, the shift lock circuit is cut off to disallow the operation of the shift lever. Therefore, when the engine is started by the remote operation means, the operation of the shift lever is prohibited, and it is possible to prevent the engine from stopping due to the operation of the shift lever, thus restarting the engine. It is possible to eliminate the action that causes it.
