PROBLEM TO BE SOLVED: To reduce wind noise generated when a plurality of cars simultaneously run in a similar direction. SOLUTION: As a simultaneous car run detecting means 1E detects cars 8A and 8B adjacent to each other running in a similar direction at the same timing, a car acceleration regulation means 1F outputs a command to one car 8B for decreasing (or increasing) acceleration without changing the highest speed of it. When both cars 8A and 8B run in the same direction, therefore, difference is generated between their runs at a specified time after departure, thereby parallel run is avoided. |
