Execution when stepping on of speed pedal 30.
First, ECU6 starts the restriction (step S1) of the output torque of electromotor 2.Then, ECU6 settings intervalometer is first
Initial value, starts countdown (step S2).Then, ECU6 judges whether the value of intervalometer is changed into 0 (step S3).
Here, being unchanged as in the case of 0 in the value for being judged as intervalometer, ECU6 judges that the change bit rate dP of drive mechanism 14 is
It is no to be more than 1 (step S4).That is, ECU6 judges whether stepping on for accelerator pedal 30 causes the output torque of electromotor 2 to rise and drive
Motivation structure 14 has started to displacement.On the other hand, it is being judged as that becoming bit rate dP is not more than in the case of 1, ECU6 makes driving power restriction
Action return to step S3.
Here, in the case where being judged as becoming bit rate dP more than 1, ECU6 judges whether the value of intervalometer is changed into 0 (step
S5).Here, being unchanged as in the case of 0 in the value for being judged as intervalometer, whether ECU6 judges to become bit rate dP into less than 1 (step
S6).That is, ECU6 judges whether the displacement of the drive mechanism 14 caused because of the driving force of drive mechanism 14 is not further added by.The opposing party
Face, be judged as become bit rate dP be not below 1 in the case of, ECU6 makes driving power restriction action return to step S5.
It is judged as intervalometer in the case of being judged as becoming bit rate dP into less than 1 in step s 6 or in step S3 or S5
Value be changed in the case of 0, ECU6 release electromotor 2 output torque restriction (step S7).When the output for releasing electromotor 2
During the restriction of torque, ECU6 makes the output torque of electromotor 2 increase so as to become request torque (step S8), terminates driving force limit
Braking is made.
The effect of driving power restriction action described above is illustrated with reference to Fig. 5.Fig. 5 is illustrated in the idle running of electromotor 2
When bend the throttle 30 situation example.
In Figure 5, transverse axis represents the moment, and the longitudinal axis represents from top to bottom accelerator pedal aperture, the output of electromotor 2 in figure
The presence or absence of torque limit, the value of intervalometer, the displacement of drive mechanism 14, the change bit rate dP of drive mechanism 14 and electromotor 2
Output torque.In addition, the output torque of the electromotor 2 being shown in broken lines represents request torque.
When stepping on of accelerator pedal 30 is detected in moment t1 accelerator pedal jaw opening sensor 31, start to limit electromotor
2 output torque, sets the intervalometer after initial value and starts countdown.In addition, stepping on correspondingly with accelerator pedal 30, start
The output torque of machine 2 rises.
In moment t2, the rising of the output torque of electromotor 2 causes drive mechanism 14 to start displacement so that drive mechanism 14
Change bit rate dP be more than 1.When no longer conjugating in moment t3 drive mechanism 14 and become bit rate dP and be changed into below 1, electromotor 2 is released
Output torque restriction, the output torque of electromotor 2 is from moment t3 to increasing between moment t4 so as to become request torque.
As described above, in the present embodiment, according to the driving condition of vehicle 1, calculate because of the driving force of drive mechanism 14
The displacement of the drive mechanism 14 for causing, limits the output torque of electromotor 2 until the displacement for calculating is not further added by, therefore, it is possible to not
