Description

上述した問題を解決するために本発明の車両制動装置では、運転者の覚醒度が閾値以下に低下したことを検出すると、車両の走行速度に応じて記憶されている制動態様を読み出して、車両の走行に制動をかける。そして予め記憶されている制動態様は、車両の走行速度が低くなるほど、制動の程度が小さい態様となっている。更に、それら制動態様は、制動動作が複数回実行され、且つ、複数回実行される制動動作のうちの初回の制動動作は、それ以降の制動動作よりも強めの制動動作となっている。 In order to solve the above-described problem, in the vehicle braking device of the present invention, when it is detected that the driver's arousal level has dropped below a threshold value, the stored braking mode is read according to the traveling speed of the vehicle, and the vehicle Apply braking to the car. The braking mode stored in advance is a mode in which the degree of braking is smaller as the traveling speed of the vehicle is lower. Further, in these braking modes, the braking operation is executed a plurality of times, and the first braking operation among the braking operations executed a plurality of times is a stronger braking operation than the subsequent braking operation .

車両の走行速度が高い場合には、ある程度の大きさの制動をかけなければ車両を速やかに減速させることができないが、かといって走行速度が低い場合に大きな制動をかけると、走行速度が急激に低下することになって後続車両から追突される虞が生じる。そこで、車両の走行速度が低くなるほど制動の程度が小さくなるような制動態様を予め記憶しておく。更に、それらの制動態様としては、制動動作が複数回実行され、且つ、複数回実行される制動動作のうちの初回の制動動作は、それ以降の制動動作よりも強めの制動動作となっているような制動態様を記憶しておく。そして、運転者の覚醒度が低下した場合には、走行速度に応じて記憶されている制動態様を読み出して車両を制動してやれば、他車から追突されることなく、車両を速やかに減速させることが可能となる。 When the running speed of the vehicle is high, the vehicle cannot be decelerated quickly unless a certain amount of braking is applied. However, if the braking is applied at a low running speed, the running speed increases rapidly. There is a risk that the vehicle will fall from the following vehicle. Therefore, a braking mode is stored in advance so that the degree of braking decreases as the traveling speed of the vehicle decreases. Furthermore, as those braking modes, the braking operation is executed a plurality of times, and the first braking operation among the braking operations executed a plurality of times is a stronger braking operation than the subsequent braking operation. Such a braking mode is stored. And when a driver | operator's arousal level falls, if the braking mode memorize | stored according to driving speed is read and a vehicle is braked, a vehicle will be decelerated rapidly, without being collided from another vehicle. Is possible.
