Abstract

PROBLEM TO BE SOLVED: To solve a problem that the equilibrium point of a torque corresponding to a speed difference between speed information and a constant-speed target speed is changed and the accuracy of the constant-speed target speed is deteriorated because the magnitudes of running resistances differ depending on speed zones in the constant-speed control of an electric vehicle controller.SOLUTION: A plurality of constant-speed control torque patterns added with the running resistances corresponding to the speed zones are prepared previously in order to solve the problem, and an optimum constant-speed control torque pattern is selected according to a speed upon starting the constant-speed control. The method is effective for improving the accuracy of a constant-speed control speed with respect to the constant-speed target speed.

以上のような電気車制御装置の定速制御は、速度域による走行抵抗の大きさが異なるため、定速目標速度との差速度に応じたトルクの均衡点が変化し、定速目標速度の精度が悪化する。特に低速域と高速域の両速度域にて定速制御を行うような場合は、精度の悪化が顕著となる。 In the constant speed control of the electric vehicle control device as described above, since the magnitude of the running resistance differs depending on the speed range, the torque equilibrium point changes according to the difference speed from the constant speed target speed, and the constant speed target speed Accuracy deteriorates. In particular, when the constant speed control is performed in both the low speed range and the high speed range, the accuracy is significantly deteriorated.

In the electric vehicle control device having the above, a plurality of constant speed control patterns taking into account the running resistance according to the speed range are prepared, and the constant speed control is performed by switching the pattern to be used according to the speed at which the constant speed control is started.

図１に本発明を適用した定速制御ブロック図を示す。図１は図２に対して速度域毎に走行抵抗を加味した定速制御トルクパターンを用意し、また、速度域判別用の速度コンパレータ１１を用意することで、定速制御の目標速度に対する制御の精度向上を図ることが出来る。なお、ここでは定速制御トルクパターンを低速、高速の二つ実例で説明するが、速度が大きいときは随時定速制御パターンの数の増加に応じて同様に実施可能である。 FIG. 1 shows a constant speed control block diagram to which the present invention is applied. FIG. 1 provides a constant speed control torque pattern in which a running resistance is added for each speed range with respect to FIG. 2 and also provides a speed comparator 11 for speed range discrimination, thereby controlling the target speed for constant speed control. Accuracy can be improved. Here, the constant speed control torque pattern will be described with two examples of low speed and high speed, but when the speed is high, the constant speed control torque pattern can be similarly implemented according to an increase in the number of constant speed control patterns.
