本発明は、アンチスキッド装置に係り、特に油圧制御用
ソレノイドの断線を検出するに好適な回路に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an anti-skid device, and particularly to a circuit suitable for detecting disconnection of a hydraulic control solenoid.
従来は、ソレノイドが断線した時、アンチスキッド装置
は動作しないが通常のブ１〜−キ装置としては動作する
ため、積極的に断線を検出して警報する装置はなかった
。Conventionally, when a solenoid is disconnected, the anti-skid device does not operate, but operates as a normal brake device, so there has been no device that proactively detects the disconnection and issues an alarm.
この為、急制動時になって初めて故障している事がわか
るため、アンチスキッド装置本来の機能が発揮できず、
危険を防げない恐れがあった。For this reason, the malfunction is only known during sudden braking, and the anti-skid device is unable to perform its original function.
There was a fear that the danger could not be prevented.
本発明の目的はソトノイドが断線した事を検出して、警
報を発つし、危険を未然に防ぐことが出来るアンチスキ
ッド装置の断線警報回路を提供するにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a disconnection alarm circuit for an anti-skid device that can detect disconnection of a sotonoid and issue an alarm to prevent danger.
本発明は制御用トランジスタに並列に抵抗を接続し、ソ
レノイドとの接続点の電位を１ヘランジスクの入力とし
て断線の有無を検出しこの後段に時間設定回路及び警報
回路を設けて警報する様にした回路を提供する。The present invention connects a resistor in parallel to the control transistor, uses the potential at the connection point with the solenoid as an input to detect the presence or absence of disconnection, and provides a time setting circuit and an alarm circuit at the subsequent stage to issue an alarm. Provide the circuit.
第１図は本発明であるアンチスキッド装置の断線警報回
路を示す一実施例で１は電源、２はアンチスキッド制御
回路、３は制御トランジスタ、４はソレノイドである。FIG. 1 shows an embodiment of a disconnection alarm circuit for an anti-skid device according to the present invention, in which 1 is a power source, 2 is an anti-skid control circuit, 3 is a control transistor, and 4 is a solenoid.
５はトランジスタ、６，７゜８は抵抗であり、９は時間
設定回路、１０は警報回路、１１は接続点である。5 is a transistor, 6,7°8 is a resistor, 9 is a time setting circuit, 10 is an alarm circuit, and 11 is a connection point.
この回路において、アンチスキッド制御回路２の動作が
動作せず、ソレノイド４が断線していない時は次の様に
ｆＳる。In this circuit, when the anti-skid control circuit 2 does not operate and the solenoid 4 is not disconnected, fS occurs as follows.
トランジスタ３は導通していない為、接続点１１の電位
は、抵抗６とソ１／ノイド４の抵抗及び抵抗７の並列合
成抵抗の比で分割される。Since the transistor 3 is not conductive, the potential at the connection point 11 is divided by the ratio of the parallel combined resistance of the resistor 6, the resistance of the solenoid 4, and the resistor 7.
抵抗６の値をソレノイド４の抵抗値より十分大きくして
おけば、電位が下る為、トランジスタ５は導通しない。If the value of the resistor 6 is made sufficiently larger than the resistance value of the solenoid 4, the potential will drop and the transistor 5 will not conduct.
この時、抵抗８を介した出力電位は高いが、この場合、
時間設定回路９を動作させない様にしておけば、警報回
路１０は警報を発つしない。At this time, the output potential via the resistor 8 is high, but in this case,
If the time setting circuit 9 is not operated, the alarm circuit 10 will not issue an alarm.
この状態から、ソレノイド４が断線した時は、接続点１
１の電位が上り、抵抗６，７を介してトランジスタ５は
導通ずる。In this state, if solenoid 4 is disconnected, connect point 1
The potential of transistor 1 rises, and transistor 5 becomes conductive via resistors 6 and 7.
トランジスタ５が反転すると時間設定回路９が動作し、
設定時間後に反転し警報回路１０を動作させ警報するこ
とになる。When the transistor 5 is inverted, the time setting circuit 9 operates,
After a set time, the signal is reversed and the alarm circuit 10 is activated to issue an alarm.
時間設定回路９を設けたのは、急制動時におけるアンチ
スキッド装置の正常な動作と区別するためである。The reason why the time setting circuit 9 is provided is to distinguish normal operation of the anti-skid device during sudden braking.
すなわち、急制動を感知すると制御回路２が働いて、ト
ランジスタ３が導通しソレノイド４を附勢する。That is, when sudden braking is detected, the control circuit 2 operates, the transistor 3 becomes conductive, and the solenoid 4 is energized.
通常は２サイクル程度で断線し、３秒間程度持続するが
トランジスタ３が導通した時、接続点１１の電位が上り
、トランジスタ５は反転する。Normally, the disconnection occurs in about two cycles and lasts for about three seconds, but when transistor 3 becomes conductive, the potential at connection point 11 rises and transistor 5 is inverted.
この為、時間設定回路９は動作を開始するが、設定時間
を接続時間より長くしておけば、警報回路１０は動作し
ないことになる。Therefore, the time setting circuit 9 starts operating, but if the set time is made longer than the connection time, the alarm circuit 10 will not operate.
警報手段は、ランプの点灯や、ブザーを鳴らす等なんで
も良いことはもちろんである。Of course, the alarm means may be anything such as lighting a lamp or sounding a buzzer.
本発明によれば、ソレノイドが断線した時、警報を発つ
する様になり、危険を未然に防止できることになる。According to the present invention, when the solenoid is disconnected, an alarm is issued, making it possible to prevent danger.
