【発明の詳細な説明】 〔産業上の利用分野〕 本発明は自動車の走行制御方法、特にブレーキペダルと
間違えてアクセルペダルを踏み込んだ時、この誤操作を
検出して安全に走行制御する方法に関するものである。Description: TECHNICAL FIELD The present invention relates to a driving control method for an automobile, and more particularly to a method for safely controlling driving by detecting this erroneous operation when the accelerator pedal is depressed by mistake as a brake pedal. Is.
一般に、運転中にブレーキペダルとアクセルペダルとを
踏み間違えることは少ないが、車両の惰性走行中に障害
物などが不意に前方に飛び出した時や、停車中にクリー
プや路面の傾斜などによって車両が微速で前進しかけた
時、慌てた運転者がブレーキペダルと間違えてアクセル
ペダルを踏み込んでしまう可能性がある。In general, it is rare to mistake the brake pedal and accelerator pedal while driving, but when an obstacle suddenly jumps forward while the vehicle is coasting, or when the vehicle creeps or the road slopes while the vehicle is stopped, etc. When moving forward at a very low speed, a panicked driver may mistake the brake pedal for depressing the accelerator pedal.
そこで、アクセルペダルの踏力または踏込み速度が検出
レベルを越えた時、エンジンの出力を走行不能状態まで
低下させるようにすれば、車両を安全に停止させること
が可能である。Therefore, when the pedaling force or the pedaling speed of the accelerator pedal exceeds the detection level, it is possible to stop the vehicle safely by reducing the output of the engine to the inoperable state.
しかしながら、アクセルペダルの踏力や踏込み速度は運
転者によって個人差があり、例えば乱暴な運転車の場合
にはアクセルペダルの最大踏力あるいは最大踏込み速度
が通常の運転車より大きく、そのため通常の加速あるい
は発進を行う場合であっても、これを誤操作と判断して
しまう可能性がある。However, there are individual differences in the pedaling force and the pedaling speed of the accelerator pedal depending on the driver.For example, in the case of a rough driving vehicle, the maximum pedaling force or the maximum pedaling speed of the accelerator pedal is larger than that of a normal driving vehicle, and therefore, normal acceleration or starting Even when performing, there is a possibility that this may be determined as an erroneous operation.
そこで、本発明の目的は、運転者の個人差に基づく誤検
出を防止し、アクセルペダルの踏み違いによる不具合を
解消できる自動車の走行制御方法を提供することにあ
る。Therefore, it is an object of the present invention to provide a vehicle traveling control method capable of preventing erroneous detection based on individual differences among drivers and eliminating a problem caused by misstep of the accelerator pedal.
上記目的を達成するため、本発明は、アクセルペダルの

ある。To achieve the above object, the present invention, the step of detecting the stepping force or the stepping speed of the accelerator pedal, by statistically processing the detection data, the step of determining the detection level according to the characteristics of the driver, And a step of reducing the supply of at least one of fuel, intake air, and ignition pulse of the engine to an inoperable state when the depression force or the depression speed of the accelerator pedal exceeds the detection level.
通常の場合、急ブレーキ時におけるブレーキペダルの踏

けるアクセルペダルの踏力は１ｋｇ以下であり、ブレー
キペダルの踏力はアクセルペダルの踏力より遥に大き
い。したがって、検出レベルをその中間値に設定すれ
ば、アクセルペダルの踏力がこの中間値を越えた場合に

から、ペダルを踏み間違えたと判断し、燃料供給，吸気
供給，点火パルスの供給の内少なくとも１つを断つか、
あるいはアイドリング状態まで低減させることにより、
車両を安全に停止させることができる。Normally, the pedal effort of the brake pedal during sudden braking is 10 kg or more, whereas the pedal effort of the accelerator pedal during acceleration or starting is 1 kg or less, and the pedal effort of the brake pedal is much larger than the pedal effort of the accelerator pedal. . Therefore, if the detection level is set to an intermediate value, and if the accelerator pedal depressing force exceeds this intermediate value, it means that it is attempting to perform an acceleration that would not normally be possible. , Cut off at least one of fuel supply, intake supply and ignition pulse supply,
Or by reducing it to the idling state,
The vehicle can be stopped safely.
ところで、アクセルペダルの踏力や踏込み速度には個人

いる。そのため、運転者がある程度の時間運転を行え
ば、検出レベルはその運転者に応じた値になるので、信
頼性の高い誤操作検出を行うことができる。By the way, since there are individual differences in the pedaling force and the pedaling speed of the accelerator pedal, it is desirable to change the detection level accordingly. Therefore, in the present invention, the detection level according to the characteristics of the driver is determined by statistically processing the detection data of the accelerator pedal depression force or the depression speed. Therefore, if the driver drives for a certain period of time, the detection level becomes a value according to the driver, and therefore, highly reliable erroneous operation detection can be performed.

The load data is input to the memory of the microcomputer 31 (step S 1 ). Load data is compared with preset initial detection level (Step S 2), if the load data is higher than the detection level, the fuel cut is determined to be abnormal, off the intake throttle opening, or the ignition device the vehicle is stopped as a (step S 3). If the load data is lower than the detection level, the count number n is incremented by 1 (step S 4 ), and then the count number n
Is compared with a preset set value N (step S 5 ). When the count number n is smaller than the set value N, the load data is input again, and when the count number n becomes the set value N or more, the process proceeds to the statistical processing (step S 6 ) in FIG.

The average value of the number of the load data (step 7), dispersing the calculated (Step S 8) further load data as a random variable, performs the ranking of the load data from the mean value and the variance (step S 9). This ranking is judged by a table stored in advance in the microcomputer 31, and is classified into a plurality of ranks such as 0 to 1 kg, 1 to 2 kg, and 2 to 3 kg. Then, a highest ranked depression load of the accelerator pedal 1 by the driver in the running route, the value exceeds this rank is determined as a new detection level (step S 10), and returns to the main routine of FIG. 3.

The engine 5 can be stopped only by shutting off at least one of the elements. Further, not only when the supply of fuel, intake air, and ignition pulse is completely cut off, but if at least one of these three elements is reduced to an idling state, the driving force of the engine 5 becomes almost zero. Therefore, the vehicle can be naturally stopped.
