本発明の実施の形態における自動二輪車用ブレーキ駆動制御回路の回路構成例を示す回路図である。1 is a circuit diagram showing a circuit configuration example of a motorcycle brake drive control circuit in an embodiment of the present invention. FIG.

以下、本発明の実施の形態について、図１を参照しつつ説明する。
なお、以下に説明する部材、配置等は本発明を限定するものではなく、本発明の趣旨の範囲内で種々改変することができるものである。
本発明の実施の形態における自動二輪車用ブレーキ駆動制御回路１００は、例えば、従来から良く知られた基本的構成を有するブレーキ制御装置において用いられるものである。
かかる自動二輪車用ブレーキ駆動制御回路１００は、特に、ブレーキ駆動制御装置におけるホイールシリンダ（図示せず）へのブレーキ液の流入や、リザーバ（図示せず）からのブレーキ液の放出等を制御する第１乃至第４の電磁切換弁１〜４と、ハイサイドスイッチ６、第１乃至第４のローサイドスイッチ用トランジスタ７ａ〜７ｄを主たる構成要素として構成されたものとなっている。Hereinafter, an embodiment of the present invention will be described with reference to FIG.
The members and arrangements described below do not limit the present invention and can be variously modified within the scope of the gist of the present invention.
The motorcycle brake drive control circuit 100 according to the embodiment of the present invention is used, for example, in a brake control device having a basic configuration well known in the art.
The motorcycle brake drive control circuit 100 particularly controls the inflow of brake fluid into a wheel cylinder (not shown) and the release of brake fluid from a reservoir (not shown) in the brake drive control device. The first to fourth electromagnetic switching valves 1 to 4, the high-side switch 6, and the first to fourth low-side switch transistors 7a to 7d are configured as main components.

第１の電磁切換弁１は、フロントホイールシリンダ（図示せず）へのブレーキ液の流入を制御する電磁切換弁であり、駆動制御のための電磁コイル１ａを有して構成されたものとなっている。
第２の電磁切換弁２は、図示されないフロントホイールシリンダからのブレーキ液の排出を制御する電磁切換弁であり、駆動制御のための電磁コイル２ａを有して構成されたものとなっている。The first electromagnetic switching valve 1 is an electromagnetic switching valve that controls the inflow of brake fluid into a front wheel cylinder (not shown), and is configured to have an electromagnetic coil 1a for drive control. ing.
The second electromagnetic switching valve 2 is an electromagnetic switching valve that controls the discharge of brake fluid from a front wheel cylinder (not shown), and is configured to have an electromagnetic coil 2a for drive control.

また、第３の電磁切換弁３は、リアホイールシリンダ（図示せず）へのブレーキ液の流入を制御する電磁切換弁であり、駆動制御のための電磁コイル３ａを有して構成されたものとなっている。
さらに、第４の電磁切換弁４は、図示されないリアホイールシリンダからのブレーキ液の排出を制御する電磁切換弁であり、駆動制御のための電磁コイル４ａを有して構成されたものとなっている。The third electromagnetic switching valve 3 is an electromagnetic switching valve that controls the flow of brake fluid into a rear wheel cylinder (not shown), and is configured to have an electromagnetic coil 3a for drive control. It has become.
Further, the fourth electromagnetic switching valve 4 is an electromagnetic switching valve that controls the discharge of brake fluid from a rear wheel cylinder (not shown), and is configured to have an electromagnetic coil 4a for drive control. Yes.

これら第１乃至第４の電磁切換弁１〜４の各電磁コイル１ａ，２ａ，３ａ，４ａの一方の端子は相互に接続されて、ハイサイドスイッチ６を介して電源電圧ＶＢが印加されるようになっている。
本発明の実施の形態におけるハイサイドスイッチ６は、Ｎチャンネルタイプの２つのハイサイド用第１及び第２のＭＯＳ型電界効果トランジスタ（以下「ＭＯＳＦＥＴ」と称する）８，９を有して構成されたなるものとなっている。すなわち、ハイサイド用第１のＭＯＳＦＥＴ８のドレインは、図示されない車両用バッテリの電源電圧ＶＢが印加されるようになっている一方、ソースは、逆接防止用素子としてのハイサイド用第２のＭＯＳＦＥＴ９のソースに接続されており、このハイサイド用第２のＭＯＳＦＥＴ９のドレインは、電磁コイル１ａ，２ａ，３ａ，４ａの一方の端子に接続されている。One terminal of each of the electromagnetic coils 1 a, 2 a, 3 a, 4 a of the first to fourth electromagnetic switching valves 1 to 4 is connected to each other so that the power supply voltage VB is applied via the high side switch 6. It has become.
The high-side switch 6 according to the embodiment of the present invention includes two high-side first and second MOS field effect transistors (hereinafter referred to as “MOSFETs”) 8 and 9 of N-channel type. It has become something. That is, the power source voltage VB of a vehicle battery (not shown) is applied to the drain of the first high-side MOSFET 8 while the source is the second MOSFET 9 for high-side as a reverse connection prevention element. The drain of the second MOSFET 9 for high side is connected to one terminal of the electromagnetic coils 1a, 2a, 3a, 4a.

なお、ハイサイド用第２のＭＯＳＦＥＴ９は、ハイサイド用第１のＭＯＳＦＥＴ８に対して逆接続状態とされており、図示されない車両用バッテリが逆接続された場合に通常時とは逆方向に流れる電流を阻止して逆電流による回路素子の破壊、故障を防止する機能を果たすものとなっている。
また、ハイサイド用第１のＭＯＳＦＥＴ８のドレイン・ソース間には、ドレイン側にカソードが接続されるようにして内部生成された逆接防止用ダイオード８ａが、同様に、ハイサイド用第２のＭＯＳＦＥＴ９のドレイン・ソース間には、ドレイン側にカソードが接続されるようにして内部生成された逆接防止用ダイオード９ａが、それぞれ設けられたものとなっている。The high-side second MOSFET 9 is in a reverse connection state with respect to the high-side first MOSFET 8, and when a vehicle battery (not shown) is reversely connected, the current that flows in the reverse direction from the normal time This prevents the circuit element from being broken or broken by reverse current.
In addition, a reverse connection prevention diode 8a internally generated so that the cathode is connected to the drain side between the drain and the source of the high-side first MOSFET 8 is similarly connected to the high-side second MOSFET 9. Between the drain and the source, a reverse connection preventing diode 9a internally provided so that the cathode is connected to the drain side is provided.

そして、ハイサイド用第１及び第２のＭＯＳＦＥＴ８，９のゲートは相互に接続されて、車両の動作制御を行う動作制御用電子制御ユニット（図示せず）から、動作制御のためのゲート信号が適宜印加されるようになっている（詳細は後述）。
さらに、ハイサイド用第１のＭＯＳＦＥＴ８のソースとハイサイド用第２のＭＯＳＦＥＴ９のソースの相互の接続点とグランドとの間には、図示されないリザーバ内のブレーキ液を吸い上げてマスタシリンダ（図示せず）へブレーキ液を還流させるための油圧ポンプ用モータ５が直列接続されたものとなっている。なお、油圧ポンプ用モータ５のハイサイドスイッチ６との接続点には、油圧ポンプモニタ回路５０が接続されており、電流値等の予め定められたデータが取得されて、図示されない動作制御用電子制御ユニットにおける油圧ポンプ用モータ５の動作監視処理等に供されるようになっている。The gates of the high-side first and second MOSFETs 8 and 9 are connected to each other, and a gate signal for operation control is received from an operation control electronic control unit (not shown) that controls the operation of the vehicle. Appropriate application is made (details will be described later).
Further, a brake fluid in a reservoir (not shown) is sucked up between a connection point between the source of the high-side first MOSFET 8 and the source of the high-side second MOSFET 9 and the ground, and a master cylinder (not shown). ) Is connected in series with a hydraulic pump motor 5 for recirculating the brake fluid. A hydraulic pump monitor circuit 50 is connected to a connection point of the hydraulic pump motor 5 with the high-side switch 6, and predetermined data such as a current value is acquired, and operation control electronics (not shown) are obtained. It is used for operation monitoring processing of the hydraulic pump motor 5 in the control unit.

また、電磁コイル１ａ，２ａ，３ａ，４ａの他方の端子は、それぞれ対応する第１乃至第４のローサイドスイッチ用トランジスタ７ａ〜７ｄを介してグランドに接続されるようになっている。
すなわち、本発明の実施例において、第１乃至第４のローサイドスイッチ用トランジスタ７ａ〜７ｄには、ＮチャンネルＭＯＳＦＥＴが用いられており、そのドレインが対応する電磁コイル１ａ，２ａ，３ａ，４ａの他方の端子に、ソースがグランドに接続されたものとなっている。The other terminals of the electromagnetic coils 1a, 2a, 3a, 4a are connected to the ground via corresponding first to fourth low-side switching transistors 7a-7d, respectively.
That is, in the embodiment of the present invention, N-channel MOSFETs are used for the first to fourth low-side switch transistors 7a to 7d, and the drains thereof correspond to the other of the electromagnetic coils 1a, 2a, 3a, 4a. The source is connected to the ground.

そして、第１乃至第４のローサイドスイッチ用トランジスタ７ａ〜７ｄの各ゲートには、ハイサイドスイッチ６同様、図示されない動作制御用電子制御ユニットから、第１乃至第４の電磁切換弁１〜４の各電磁コイル１ａ，２ａ，３ａ，４ａの通電制御のためのゲート信号（以下、説明の便宜上「ローサイド用ゲート信号」と称する）が印加されるようになっている。  The gates of the first to fourth low-side switch transistors 7a to 7d are connected to the first to fourth electromagnetic switching valves 1 to 4 from an operation control electronic control unit (not shown) as in the high-side switch 6. A gate signal for energization control of each electromagnetic coil 1a, 2a, 3a, 4a (hereinafter referred to as “low-side gate signal” for convenience of explanation) is applied.

次に、上記回路構成における動作について説明する。
上述の回路構成においては、従来と異なり、第１乃至第４の電磁切換弁１〜４の各電磁コイル１ａ，２ａ，３ａ，４ａの通電制御を行うハイサイド用第１のＭＯＳＦＥＴ８を、油圧ポンプ用モータ５の通電制御にも用いるようにしたので、ハイサイド用第１のＭＯＳＦＥＴ８のゲートには、各電磁コイル１ａ，２ａ，３ａ，４ａの通電制御のためのゲート信号（以下、説明の便宜上「コイル制御用ゲート信号」と称する）が従来同様に印加されると共に、油圧ポンプ用モータ５の通電制御のためのゲート信号（以下、説明の便宜上「ポンプ制御用ゲート信号」）が、それぞれのタイミングで印加されることとなる。
なお、上述のゲート信号は、例えば、ＰＷＭ信号のようなオン・オフ制御信号である。Next, the operation in the above circuit configuration will be described.
In the circuit configuration described above, unlike the prior art, the high-side first MOSFET 8 that controls the energization of the electromagnetic coils 1a, 2a, 3a, and 4a of the first to fourth electromagnetic switching valves 1 to 4 is replaced by a hydraulic pump. Since it is also used for the energization control of the motor 5, the gate signal for energization control of the electromagnetic coils 1a, 2a, 3a, 4a is connected to the gate of the first high-side MOSFET 8 (hereinafter, for convenience of explanation). (Referred to as “coil control gate signal”) is applied in the same manner as before, and a gate signal for energization control of the hydraulic pump motor 5 (hereinafter referred to as “pump control gate signal” for convenience of explanation) It will be applied at the timing.
The above gate signal is an on / off control signal such as a PWM signal.

しかして、まず、第１乃至第４の電磁切換弁１〜４の各電磁コイル１ａ，２ａ，３ａ，４ａの通電制御のためコイル制御用ゲート信号は、動作制御用電子制御ユニット（図示せず）において従来同様にして実行される電磁切換弁駆動のための駆動制御処理に基づいて、ローサイド用ゲート信号と共に、適宜生成され、コイル制御用ゲート信号は、ハイサイド用第１及び第２のＭＯＳＦＥＴ８，９のゲートに印加されるようになっている。また、ローサイド用ゲート信号は、ローサイドスイッチ用トランジスタ７ａ〜７ｄの内、ブレーキ操作の状況に応じて選択されたトランジスタのゲートに印加されるようになっている。  Therefore, first, the coil control gate signal for energization control of each of the electromagnetic coils 1a, 2a, 3a, 4a of the first to fourth electromagnetic switching valves 1 to 4 is an electronic control unit for operation control (not shown). ) Is appropriately generated together with the low-side gate signal based on the drive control process for driving the electromagnetic switching valve executed in the same manner as in the prior art, and the high-side first and second MOSFETs 8 are generated as the coil control gate signal. , 9 are applied to the gates. Further, the low-side gate signal is applied to the gate of the transistor selected in accordance with the state of the brake operation among the low-side switch transistors 7a to 7d.

コイル制御用ゲート信号及びローサイド用ゲート信号が、それぞれ対応するゲートへ印加されると、ハイサイド用第１のＭＯＳＦＥＴ８が導通状態となると共に、ローサイドスイッチ用トランジスタ７ａ〜７ｄの内、ローサイド用ゲート信号が印加されたトランジスタが導通状態となり、電磁コイル１ａ，２ａ，３ａ，４ａの内、対応する電磁コイルに対して、ハイサイド用第１のＭＯＳＦＥＴ８、ハイサイド用第２のＭＯＳＦＥＴ９の逆接防止用ダイオード８ａを介して電源電流が流れ込み、ローサイドスイッチ用トランジスタ７ａ〜７ｄの内、導通状態にあるトランジスタを介してグランドへ流入することとなる。
これによって、第１乃至第４の電磁切換弁１〜４の内、電源電流が流れた電磁切換弁が動作せしめられ、ブレーキ液の流入、流出が制御され、所望するブレーキ力の制御が得られることとなる。When the coil control gate signal and the low-side gate signal are respectively applied to the corresponding gates, the high-side first MOSFET 8 becomes conductive, and among the low-side switch transistors 7a to 7d, the low-side gate signal The transistor to which is applied becomes conductive, and the reverse-side prevention diodes of the high-side first MOSFET 8 and the high-side second MOSFET 9 with respect to the corresponding electromagnetic coil among the electromagnetic coils 1a, 2a, 3a, and 4a. The power supply current flows through 8a and flows into the ground through the transistors in the conductive state among the low-side switch transistors 7a to 7d.
As a result, among the first to fourth electromagnetic switching valves 1 to 4, the electromagnetic switching valve through which the power supply current flows is operated, the inflow and outflow of the brake fluid are controlled, and the desired brake force control is obtained. It will be.

本発明の実施の形態においては、上述のようにコイル制御用ゲート信号によりハイサイド用第１のＭＯＳＦＥＴ８が導通状態となるため、本来の動作タイミングと異なるタイミングで油圧ポンプ用モータ５への通電も同時になされることとなるが、油圧ポンプ用モータ５が本来の動作タイミングとは異なるタイミングで動作してもブレーキ制御に支障を来すことはない。  In the embodiment of the present invention, since the first high-side MOSFET 8 is turned on by the coil control gate signal as described above, the hydraulic pump motor 5 is energized at a timing different from the original operation timing. Although it is performed at the same time, even if the hydraulic pump motor 5 operates at a timing different from the original operation timing, the brake control is not hindered.

一方、動作制御用電子制御ユニット（図示せず）からは、上述のコイル制御用ゲート信号及びローサイド用ゲート信号とは別個に、油圧ポンプ用モータ５の通電駆動のためのポンプ制御用ゲート信号が、ハイサイド用第１のＭＯＳＦＥＴ８のゲートに印加されてハイサイド用第１のＭＯＳＦＥＴ８が導通状態とされ、油圧ポンプ用モータ５への通電が行われ、油圧ポンプ用モータ５が動作せしめられることとなる。  On the other hand, from an electronic control unit for operation control (not shown), a pump control gate signal for energization driving of the hydraulic pump motor 5 is provided separately from the above-described coil control gate signal and low side gate signal. The high-side first MOSFET 8 is applied to the gate of the first high-side MOSFET 8 to turn on, the energization of the hydraulic pump motor 5 is performed, and the hydraulic pump motor 5 is operated. Become.

ここで、ポンプ制御用ゲート信号は、基本的には、従来同様に動作制御用電子制御ユニット（図示せず）において生成、出力されるもので、従来、別個に設けられていた油圧ポンプ用モータ５の駆動回路（図示せず）へ印加されていたものと実質的に同一のものである。
ポンプ制御用ゲート信号がハイサイド用第１のＭＯＳＦＥＴ８のゲートに印加されて、ハイサイド用第１のＭＯＳＦＥＴ８が導通状態とされても、この場合、ローサイド用ゲート信号は発生されていないため、第１乃至第４の電磁切換弁１〜４が動作状態とされることはなく、これらの不用意な動作を招くことはない。Here, the pump control gate signal is basically generated and output in an operation control electronic control unit (not shown) as in the prior art. Conventionally, a hydraulic pump motor provided separately. 5 is substantially the same as that applied to the drive circuit (not shown).
Even when the pump control gate signal is applied to the gate of the high-side first MOSFET 8 and the high-side first MOSFET 8 is turned on, in this case, the low-side gate signal is not generated. The 1st thru | or 4th electromagnetic switching valve 1-4 is not made into an operation state, and these careless operations are not caused.

さらなる回路の簡素化による軽量化、小型化が所望される自動二輪車に適用できる。  The present invention can be applied to a motorcycle that is desired to be reduced in weight and size by further simplifying the circuit.
