JPS59230855A - Alarming device of antilock motion - Google Patents

Abstract

PURPOSE:To make danger of lock of a wheel avoid by urging pumping brake operation by alarming a matter that an antilock signal is generated at the time of braking of a motor car to a driver of a succeeding car, by making an alarming lamp light through the antilock signal. CONSTITUTION:At the time of obtaining brake force by supplying hydraulic pressure generated by a master cylinder 2 through stepping of a brake pedal 1 by adjusting it appropriately by an actuator 3, a speed of a wheel 5 is detected by a speed sensor 6 and the detected signal is applied to a microcomputor 7. When either lock of the wheel is detected or foreseen, an antirock signal is sent out to the actuator 3 and the lock is released or prevented by making hydraulic pressure of a brake adjust. The above matter is alarmed to a succeeding car by making an alarming lamp 8 of antilock motion provided at a position wherein the lamp is easy to be seen by the succeeding car act by the antilock signal.

Description

[Detailed Description of the Invention] (a) Field of Industrial Application This invention relates to an anti-lock activation warning device, which alerts following vehicles by means of flashing lamps, etc. when anti-lock activation occurs during braking of a vehicle. This relates to a device that emits.

(B) Prior art When a vehicle brakes suddenly or when braking on a slippery road, when a wheel lock is detected or predicted, the brakes are temporarily loosened and the vehicle brakes automatically. The function that ensures running stability and maneuverability of 1XIJ vehicles has long been known as an anti-lock function, and recently there has been an increasing trend in the number of cars equipped with anti-lock devices.

(c) Problems to be solved by the invention Although anti-lock devices were developed along with advances in electronic control technology, they are a factor in the high cost of automobiles, and are common in older automobiles. For this reason, the majority of automobiles currently do not have anti-lock devices.

On the other hand, when cars are running one behind the other, the driver of the car behind often operates the brakes while looking at the brake lights of the car in front, or the car in front is equipped with an anti-lock device. If the vehicle behind is not equipped with this, the driver of the vehicle behind will not notice such a difference, and will normally operate the brakes in accordance with the lighting of the brake lights of the vehicle in front.

If this happens, the vehicle behind the vehicle that is not equipped with an anti-lock device will be in a dangerous situation because its wheels will lock and cause it to skid or the stopping distance will become longer.

This invention aims to solve these problems.

B.) Means for Solving the Problems In order to achieve the above-mentioned object, the present invention operates a warning lamp provided on a vehicle by an anti-lock signal sent from a computer of an anti-lock device. It is.

(E) The embodiment diagram shows a basic system diagram of the present invention, in which 1 is a brake pedal, 2 is a mask cylinder, 3 is an actuator, 4 is a brake, 5 is a wheel, and the mask cylinder 2 The brake 4 is actuated by appropriately adjusting the hydraulic pressure generated in the actuator 3.

Further, a wheel rotation speed sensor 6 is attached to the wheel 5, and its detection signal is input to the microcomputer 7. When the microcomputer 7 detects or predicts that the wheels 5 are locked due to a change in the wheel rotational speed based on the detection signal, it sends an anti-lock signal to the actuator 3 and adjusts the brake fluid pressure, for example, the brake 4. Release or prevent the wheels from locking by repeating the release and return within a short period of time.

The above description is well known in the conventional anti-lock device, but in the case of the present invention, the anti-lock activation warning lamp 8 is provided at an appropriate position of the automobile, especially at a position easily visible to the following vehicle, and the computer 7 (as appropriate) An anti-lock signal is sent to the lamp 8 (via a suitable interface), and the anti-lock signal is activated. The action of lamp 8 is
It may be sufficient to simply turn on the light, but it may also be made to blink according to the above-mentioned signal, or the illuminance may be changed.In short, it is good as long as it can warn the following vehicle that the anti-lock action is being performed.

The lamp 8 may also be connected to the output portion of the actuator 3, ie, to the brake hydraulic pressure circuit, via a suitable transducer 9, as shown by the chain line in the figure. Anti-lock control is performed by repeatedly releasing and returning the brake 4, that is, by repeatedly increasing and decreasing brake fluid pressure, so changes in fluid pressure are converted into electrical signals and the lamp 8 is made to blink. , you can change the illumination intensity.

Incidentally, the lamp 8 may also be used as a normal brake lamp and perform the normal brake lamp display function except during anti-lock control.

(Effects) As mentioned above, this invention activates the warning lamp based on the anti-lock signal, so the driver of the rear car will not have to apply the brakes to follow the car in front due to the warning from the lamp. .

On the other hand, if the rear vehicle brakes in response to the warning from the front vehicle's lamp, the rear vehicle also performs a so-called hopping rake operation, thereby avoiding the risk of wheel locking.

In any case, if the device of the present invention is used, it will be safe even if some cars are equipped with an anti-lock device and others are not.
