PROBLEM TO BE SOLVED: To provide a drive controller of a vehicle capable of preventing overspeed of a motor generator even when an antilock brake system breaks down.SOLUTION: A drive controller 20 includes: an antilock brake system 15 for preventing driven wheels 7 from being held in a lock state when a driver suddenly applies the brakes; and an ECU 10 for setting an upper limit value of rotational speed of an engine 2. When it is determined that the antilock brake system 15 is not broken down, the ECU 10 sets a first upper limit value as the upper limit value of the rotational speed of the engine 2, and when it is determined that the antilock brake system 15 is broken down, the ECU sets a second upper limit value less than the first upper limit value, as the upper limit value of the rotational speed of the engine 2.SELECTED DRAWING: Figure 1 |
