パターン電圧が出力される。 When a speed control command is given in FIG. 4, a command to close LBs is given from block 2, and the main circuit is configured. Further, a target speed is set by block 9 in accordance with the speed control command, and the amount of deviation from the vehicle speed detected by speed generator 4 and block 10 is determined. Next, the brake notch corresponding to the deviation amount is outputted by the speed control pattern 11, and the specified brake notch is outputted by the brake force adjustment device 12.
A brake force pattern voltage corresponding to the state of the variable load 13 at that time is output.

合の速度偏差に対応する勾配加速力を示す。 FIG. 5 shows the braking force corresponding to the brake notch when the vehicle is full and empty, and the gradient acceleration force corresponding to the speed deviation when the target speed is 70 km/h.
今、車両が勾配io／ooであるような下り勾配を
走行中、運転士からの抑速指令によつて目標速度
（70Km／ｈ）が設定されているものとする。 Assume that the vehicle is currently traveling on a downhill slope with a slope of io/oo, and a target speed (70 km/h) is set by a speed reduction command from the driver.

If B 4 notches are specified and the braking force at B 4 notches can be set to a braking force equivalent to the acceleration force that changes depending on the occupancy rate at that time, the vehicle will be at a speed of V 3 Km/h. When the vehicle is full, the brake force is BE 4 , and when it is empty, the brake force is BE′ 4 to balance the speed.
本実施例によれば、目標速度との速度偏差によ

The speed can be balanced at a constant speed.

となる。 Next, when the gradient condition changes from io/oo to i'o/oo, the vehicle speed will change as the gradient acceleration force changes, but in this control method, the vehicle speed will change depending on the deviation between the target speed and the vehicle speed. Outputs the brake force with a deviation of 0 km/
Since control is performed with h as the target, the equilibrium speed remains constant within a certain deviation range with respect to changes in slope.
第６図に勾配が変化した場合の速度変化とブレ
ーキ力の関係を示す。 FIG. 6 shows the relationship between speed change and braking force when the slope changes.
すなわち、第６図において車両が、勾配io／oo

ことがわかる。 That is, in FIG. 6, the vehicle has a slope of io/oo
Under the slope condition of 70km/h ~ 70+ΔV 1
It is assumed that the speed is balanced within the range of Km/h, and the gradient acceleration force at this time is f 1 Kg. If the gradient changes to i′o/oo, the gradient acceleration force is
f 2 Kg and the vehicle has a speed of 70 Km/h ~ 70−ΔV 1 Km/
The speed will be balanced within the range of h. In this case, the vehicle will move to a target speed of 70
It can be seen that a constant speed is maintained within a speed deviation of ±ΔV 1 from Km/h.

According to the present invention, even if the vehicle weight changes depending on the occupancy rate, the equilibrium speed will always remain constant, and even if the slope changes, the equilibrium speed will always remain constant within a speed range with a certain deviation width from the target speed. It becomes constant.
