PROBLEM TO BE SOLVED: To make the driving operation property excellent by setting a speed- reference signal at the lowest speed when the signal outputs are not outputted from an acceleration pedal and a brake pedal, and performing coasting control driving, in which the torque reference signal is the minimum torque. SOLUTION: When pushing for both of an acceleration pedal 1 and a brake pedal is stopped, only the speed reference signal of a lowest-speed-reference generating part 9 is inputted into a high-priority circuit 10, and the speed reference signal is imparted into a VVVF inverter. At this time, since the signals from both sensors of the acceleration pedal 1 and the brake pedal 2 disappear, only the torque reference signal of a lowest-torque reference generating part 12 is inputted into a high-priority circuit part 11. The minimum-torque reference signal is imparted into the VVVF inverter from the high-priority circuit part 11. Therefore, the coasting control for speed reduction at the low torque can be performed. In this way, the driving operation property can be made excellent. |
