に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an appropriate inter-vehicle distance display device that can display a safe and appropriate inter-vehicle distance to a vehicle in front. In particular, the present invention relates to an inter-vehicle distance display device that detects vehicle speed, loaded weight, and driving environment, and displays a safe and appropriate inter-vehicle distance corresponding to the detected output.
前車に追従して走行するときには、前車の動きによく注
意し前車が急停止しても追突しないような安全な車間距
離を保つ必要がある。When following the vehicle in front of you, you need to pay close attention to its movements and maintain a safe following distance to avoid rear-ending collisions even if the vehicle in front of you suddenly stops.
車間距離は、そのときの天候や道路の状態、積載重量、
車両速度などにより適正に変えなければならない。安全
な車間距離とは、前車との間に停＋に距離と同じ程度の
距離を保つことであり、従って例えば車両速度を増せば
停止ｌ−距離ｔ）長くなるので、それなりに車間距離も
多くとらなければならない。The distance between vehicles depends on the weather, road conditions, loaded weight,
It must be changed appropriately depending on vehicle speed, etc. A safe following distance is to maintain a distance equal to the stopping distance between you and the vehicle in front. Therefore, for example, if you increase the speed of the vehicle, the stopping distance t) will increase, so the following distance will also increase accordingly. I have to take a lot.
従来、このような安全な車間距離を定量的に運転者に表

、実際には運転者が車両速度に応した停止り距離のデー
タとその運転者自身の経験とに基づいて独自に判断し、
あるいは直感により安全と思われる車間距離を決めてい
る。Until now, no device has been developed that quantitatively displays such a safe inter-vehicle distance to the driver to alert the driver. Therefore, in reality, the driver makes his own judgment based on the stopping distance data according to the vehicle speed and his own experience.
Or, based on intuition, they determine a distance between vehicles that is considered safe.
このように車間距離は、運転者の判断あるいは直感のみ
に委ねられでいるので、多岐にわたる車両の走行条件に
対する誤った判断により、あるいは独善的な直感により
前車との間に安全な車間距離をあけることを怠ることが
ある。In this way, the distance between vehicles is left solely to the driver's judgment or intuition. Therefore, due to incorrect judgment regarding a wide variety of vehicle driving conditions, or due to self-righteous intuition, it is possible to find a safe distance between the vehicle in front and the vehicle in front. Sometimes I forget to open it.

Connected to the microcomputer 4 is a memory 5 that stores safe and appropriate inter-vehicle distances calculated in advance for various vehicle speeds, loaded weights, and inclination angles. The output of the microcomputer 4 is connected to an inter-vehicle distance display section 6 provided at the driver's seat.

正な車間距離を表示させることができる。The slope of this road is one of the driving environments, and there are various other factors in the driving environment, such as the condition of the road surface and whether it is day or night, and these are automatically detected by each sensor and imported into the microcomputer 4. , it can also be used as a parameter for calculating a safe and appropriate inter-vehicle distance. For example, a well-known raindrop sensor detects raindrops to detect road surface conditions, and a well-known illuminance sensor is used to detect day and night conditions and when driving in a tunnel, thereby displaying a more reliable, safe and appropriate following distance. can be done.

In this case, by operating each manual switch when the road surface is wet due to rain or when driving at night, a safe and appropriate inter-vehicle distance for the driving environment can be displayed.
しかし、いずれの場合でも表示される安全な車間距離は
