It is an operation explanatory view showing a state at the time of operation of automatic braking and at the time of operation stop.

As shown in FIGS. 1 and 2, a four-wheeled vehicle V equipped with an automatic braking control device according to the present invention has left and right driving wheels, in which the driving force of an engine E is transmitted via a transmission T. Front wheels WFL, WFR and left and right rear wheels WRL, WR, which are driven wheels that rotate as the vehicle V travels
R. A brake pedal 1 operated by a driver is connected to a master cylinder 3 via an electronically controlled negative pressure booster 2. The negative pressure booster 2 mechanically boosts the depression force of the brake pedal 1 to
At the same time, the master cylinder 3 is operated by a braking command signal from the electronic control unit U without automatic operation of the brake pedal 1 during automatic braking.

A pair of output ports 8 of the master cylinder 3
Reference numeral 9 is connected to brake actuators 5FL, 5FR, 5RL, 5RR provided on the front wheels WFL, WFR and the rear wheels WRL, WRR, respectively, via the hydraulic control device 4.

On the basis of the vehicle speed of the own vehicle detected by the wheel speed sensors Sb ..., in order to maintain the inter-vehicle distance with the preceding vehicle at the set inter-vehicle distance,
The vehicle speed of the own vehicle is controlled by operating the negative pressure booster 2 and a throttle actuator (not shown). When the automatic brake release switch Sc detects that the driver has depressed the brake pedal 1 while the negative pressure booster 2 is operated according to a command from the electronic control unit U, priority is given to voluntary braking by the driver. Then, the automatic braking by the command from the electronic control unit U is stopped.

Next, a mechanism for operating the automatic braking release switch Sc will be described with reference to FIGS.

A bifurcated yoke 13 is fixed to the rear end of an input shaft 12 extending rearward from the negative pressure booster 2 fixed to the front of the dash panel 11, and is supported by a bracket 15 provided on the lower surface of the dashboard 14. An intermediate portion of the brake pedal 1 whose upper end is pivotally supported via 16 is connected to a yoke 13 via a pin 17. The brake pedal 1 is connected to a bracket 18 provided on the lower surface of the dashboard 14 via a spring 19.
, The brake pedal 1 is urged rearward.

A normally open type brake lamp lighting switch Sd supported on the lower surface of the dashboard 14 via a stay 20 is opposed to the projection 1a provided on the rear surface of the brake pedal 1 so as to be able to abut. When the brake pedal 1 is in the initial state (inoperative position) shown in FIG. 3, the projection 1a presses the actuator 21 of the brake lamp lighting switch Sd, so that the normally open type brake lamp lighting switch Sd is turned off. State. When the brake pedal 1 is depressed forward by the driver's depressing force, or when the negative pressure booster 2 is automatically operated by a command from the electronic control unit U and the brake pedal 1 moves forward, the protrusion 1a of the brake pedal 1 Actuator 21 of switch Sd for lighting brake light
, The normally open brake lamp lighting switch Sd is turned on, and the brake lamps L, L at the rear of the vehicle body are turned on. As described above, the brake lamps L and L are turned on both when the manual braking operation is performed and when the automatic braking operation is performed, so that the following vehicle can be reliably alerted.

The yoke 13 has a long hole 13 extending in the front-rear direction.
a is formed, and a pin 1 provided on the brake pedal 1 is provided.
7 is slidably engaged with the elongated hole 13a. The normally closed automatic braking release switch Sc is fixed to the brake pedal 1, and the yoke 13 is integrally provided with a switch operating portion 13 b capable of abutting the actuator 22. When the brake pedal 1 is in the initial state shown in FIG. 3, the pin 17 of the brake pedal 1 is located at the front end of the long hole 13a, and the switch operating portion 13b is opposed to the actuator 22 of the automatic braking release switch Sc. Therefore, the normally closed automatic braking release switch Sc is in the ON state. The pin 17 and the long hole 13a constitute the connecting means 23 of the present invention.

When the driver depresses the brake pedal 1 from the state shown in FIG. 3 as shown in FIG. 5, the yoke 13 whose front end of the elongated hole 13a is pushed by the pin 17 of the brake pedal 1 advances together with the input shaft 12. , The negative pressure booster 2 operates to generate a braking force. At this time, the projection 1a of the brake pedal 1 is the actuator 2 of the brake lamp lighting switch Sd.
Since the brake lamp lighting switch Sd switches from the off state to the on state, the brake lamps L, L are turned on. On the other hand, since the brake pedal 1 and the yoke 13 advance together without substantially changing the positional relationship, the switch operating portion 13b of the yoke 13 does not operate the actuator 22 of the automatic braking release switch Sc. Therefore, the load when the driver depresses the brake pedal 1 is not changed by the automatic braking release switch Sc, and it is possible to prevent the driver from feeling uncomfortable.

From the state shown in FIG. 3, as shown in FIG. 6 (a), when the negative pressure booster 2 is automatically operated by the command from the electronic control unit U and the input shaft 12 moves forward, the input shaft 12
After the yoke 13 integrated with the yoke 13 moves forward by a distance corresponding to the clearance t of the long hole 13a, the pin 17 engaged with the rear end of the long hole 13a is pulled forward, so that the brake pedal 1 is driven by the input shaft. Advance with 12. As a result, the projection 1a of the brake pedal 1 moves forward from the actuator 21, the brake lamp lighting switch Sd switches from the off state to the on state, and the brake lamps L, L are lit. When the yoke 13 moves forward with respect to the brake pedal 1 by a distance corresponding to the clearance t of the long hole 13a, the yoke 1
No. 3 switch operation unit 13b is an automatic braking release switch Sc
, The normally closed automatic braking release switch Sc is switched from the ON state to the OFF state.

From the state shown in FIG. 6A, that is, the state in which the negative pressure booster 2 is automatically operated in accordance with a command from the electronic control unit U, as shown in FIG. When the brake pedal 1 is depressed forward, first, the pin 17 provided on the brake pedal 1 moves by a distance t from the rear end to the front end of the long hole 13a of the yoke 13, so that the brake operator of the automatic braking release switch Sc provided on the brake pedal 1 22 is separated from the switch operating portion 13b of the yoke 13, and the normally closed automatic braking release switch Sc is switched from the off state to the on state.

Thus, when the automatic braking release switch Sc is switched from the off state to the on state, the electronic control unit U depresses the brake pedal 1 so that the driver performs spontaneous braking during execution of the automatic braking. Judge,
Since the automatic operation of the negative pressure booster 2 by the electronic control unit U is stopped, the negative pressure booster generates a braking force corresponding to the depression force on the brake pedal 1 by the driver.

At this time, the amount of depression of the brake pedal 1 required to switch the automatic braking release switch Sc from the off state to the on state is the minimum distance t required to operate the automatic braking release switch Sc. When the driver depresses the brake pedal 1, the automatic braking is released substantially at the same time, and not only sufficient responsiveness is ensured, but also the driver's discomfort can be minimized. Further, it is possible to detect the depression of the brake pedal 1 by the driver without affecting the automatic braking operation of the negative pressure booster 2, and it is necessary to arrange the automatic braking release switch Sc and the connecting means inside the negative pressure booster 2. Because there is no
An increase in cost and a decrease in maintainability can be avoided.

Next, a second embodiment of the present invention will be described with reference to FIG.

As is apparent from a comparison between FIGS. 3 and 7, in the first embodiment shown in FIG. 3, the switch operating portion 13b of the yoke 13 projects upward, whereas in the second embodiment shown in FIG. In this embodiment, the switch operating portion 13b of the yoke 13 projects downward, and accordingly, the automatic braking release switch Sc
It is fixed to. According to the second embodiment, the same operation and effect as those of the first embodiment can be achieved.

Next, a third embodiment of the present invention will be described with reference to FIGS.

In the third embodiment, an automatic brake release switch Sc is screwed into a mounting bracket 13c provided integrally with the yoke 13, and a switch operating portion 17a for operating an operator 22 of the automatic brake release switch Sc is connected to the pin 17. It is provided integrally. Input shaft 1 in side view
An automatic braking release switch Sc is arranged on the axis of the pin 2 and the switch operating portion 17a of the pin 17 is connected to the yoke 13
Can be moved back and forth without being inclined with respect to the yoke 13 by the pair of upper and lower guide portions 13d, 13d. , So that stable operation is possible.

When the driver depresses the brake pedal 1 from the initial state shown in FIG. 8 as shown in FIG. 10, the yoke 13 whose front end of the long hole 13a is pushed by the pin 17 of the brake pedal 1 And the negative pressure booster 2 operates to generate a braking force. At this time, since the projection 1a of the brake pedal 1 moves forward from the operator 21 of the brake lamp lighting switch Sd, the brake lamp lighting switch Sd switches from the off state to the on state, and the brake lamps L, L are lit. . On the other hand, since the brake pedal 1 and the yoke 13 move forward together without substantially changing the positional relationship, the switch operating portion 17a of the pin 17 does not operate the actuator 22 of the automatic braking release switch Sc. Therefore, when the driver depresses the brake pedal 1, the load is reduced by the automatic braking release switch S.
c does not change, and it is possible to prevent the driver from feeling uncomfortable.

From the initial state shown in FIG. 8, as shown in FIG. 11A, when the negative pressure booster 2 is automatically operated by the command from the electronic control unit U and the input shaft 12 moves forward, the input shaft 12 After the integral yoke 13 moves forward by a distance corresponding to the clearance t of the long hole 13a, the pin 17 engaged with the rear end of the long hole 13a is pulled forward, so that the brake pedal 1 can move the input shaft 12 Advance with. as a result,
When the protrusion 1a of the brake pedal 1 moves forward from the actuator 21, the brake lamp lighting switch Sd is switched from the off state to the on state, and the brake lamps L, L are lit. The yoke 13 is elongated with respect to the brake pedal 1.
Of the first switch Sc that moves forward with the yoke 13 when it moves forward by a distance corresponding to the clearance t of
Abuts against the switch operating portion 17a of the pin 17 and is pushed backward, so that the normally closed automatic braking release switch Sc is switched from the on state to the off state.

From the state shown in FIG. 11A, that is, the state in which the negative pressure booster 2 is automatically operated in response to a command from the electronic control unit U, as shown in FIG. When the brake pedal 1 is depressed forward, the pin 17 provided on the brake pedal 1
To move from the rear end to the front end by the distance t, the yoke 1
The switch operating portion 17a of the pin 17 is separated from the brake operator 22 of the automatic brake release switch Sc provided in the switch 3, and the normally closed automatic brake release switch Sc is switched from the off state to the on state.

Thus, when the automatic braking release switch Sc is switched from the off state to the on state, the electronic control unit U depresses the brake pedal 1 so that the driver performs spontaneous braking during execution of the automatic braking. Judge,
Since the automatic operation of the negative pressure booster 2 is stopped, the negative pressure booster generates a braking force corresponding to the depression force on the brake pedal 1 by the driver.

At this time, the amount of depression of the brake pedal 1 required to switch the automatic braking release switch Sc from the off state to the on state is only the distance t. When released, sufficient responsiveness can be ensured, and the driver's discomfort can be minimized.

Although the embodiments of the present invention have been described in detail, various design changes can be made in the present invention without departing from the gist thereof.

For example, in the first to third embodiments, the pin 17 is provided on the brake pedal 1 side, and the slot 13a is provided on the yoke 13 side.
However, the positional relationship may be reversed, a long hole may be provided on the brake pedal 1 side, and a pin may be provided on the yoke 13 side.

In the third embodiment, the switch operation section 17a is provided on the pin 17, but the switch operation section may be provided on the brake pedal 1 on which the pin 17 is mounted.

As described above, according to the first aspect of the present invention, the yoke is connected to the brake pedal via the connecting means so as to be relatively movable. When the pressure booster is operating, the yoke and the brake pedal are relatively moved to one side via the connecting means, and when the driver depresses the brake pedal from this state, the yoke and the brake pedal are connected via the connecting means. Since the relative movement in the other direction is performed, the automatic braking release switch is operated by the relative movement from the one side to the other side, so that the manual braking operation by the driver is performed during the automatic braking operation of the negative pressure booster. It can be detected reliably. Also, since the distance that the yoke and brake pedal can move relative to each other is the minimum distance required to activate the automatic brake release switch, the driver only needs to depress the brake pedal slightly during the automatic braking operation of the negative pressure booster to respond. The automatic braking operation can be stopped with good efficiency, and the driver's discomfort can be minimized. In addition, the manual braking operation by the driver can be detected without affecting the automatic braking operation of the negative pressure booster, and further, since there is no need to arrange the automatic braking release switch and the connecting means inside the negative pressure booster, cost increases and It is possible to avoid a decrease in maintainability.
