Vehicle controlling apparatus

1. A vehicle controlling apparatus configured to control a first motor coupled to a first drive wheel and a second motor coupled to a second drive wheel, the first drive wheel and the second drive wheel being disposed at front and rear of a vehicle, the vehicle controlling apparatus comprising:

a first slip determining unit configured to determine whether an execution condition of a first slip control is satisfied, on a basis of an idling state of the first drive wheel;

a first slip controller configured to control the first motor and maintain a slip rate of the first drive wheel at a predetermined first slip rate, in a case where the execution condition of the first slip control is determined by the first slip determining unit as being satisfied;

a second slip determining unit configured to determine whether an execution condition of a second slip control is satisfied, on a basis of an idling state of the second drive wheel;

a second slip controller configured to control the second motor and maintain a slip rate of the second drive wheel at a predetermined second slip rate, in a case where the execution condition of the second slip control is determined by the second slip determining unit as being satisfied; and

a target torque corrector configured to decrease a target torque of the second motor, in a case where the execution condition of the first slip control is determined by the first slip determining unit as being satisfied and where the execution condition of the second slip control is determined by the second slip determining unit as being unsatisfied.

2. The vehicle controlling apparatus according to claim 1 , wherein the target torque corrector is configured to decrease the target torque of the second motor on a basis of a driving force of the first drive wheel, in the case where the execution condition of the first slip control is determined by the first slip determining unit as being satisfied and where the execution condition of the second slip control is determined by the second slip determining unit as being unsatisfied.

3. The vehicle controlling apparatus according to claim 1 , wherein the target torque corrector is configured to increase the target torque of the second motor on a basis of a requested driving force of the second drive wheel, in a case where a direction of rotation of the second drive wheel is reversed after the target torque corrector has decreased the target torque of the second motor.

4. The vehicle controlling apparatus according to claim 2 , wherein the target torque corrector is configured to increase the target torque of the second motor on a basis of a requested driving force of the second drive wheel, in a case where a direction of rotation of the second drive wheel is reversed after the target torque corrector has decreased the target torque of the second motor.

5. The vehicle controlling apparatus according to claim 3 , wherein the target torque corrector is configured to increase the target torque of the second motor on the basis of the requested driving force of the second drive wheel, until the vehicle travels at a predetermined distance that exceeds a wheelbase of the vehicle.

6. The vehicle controlling apparatus according to claim 4 , wherein the target torque corrector is configured to increase the target torque of the second motor on the basis of the requested driving force of the second drive wheel, until the vehicle travels at a predetermined distance that exceeds a wheelbase of the vehicle.

7. The vehicle controlling apparatus according to claim 1 , wherein the first drive wheel comprises a front wheel and the second drive wheel comprises a rear wheel.

8. The vehicle controlling apparatus according to claim 2 , wherein the first drive wheel comprises a front wheel and the second drive wheel comprises a rear wheel.

9. The vehicle controlling apparatus according to claim 3 , wherein the first drive wheel comprises a front wheel and the second drive wheel comprises a rear wheel.

10. The vehicle controlling apparatus according to claim 4 , wherein the first drive wheel comprises a front wheel and the second drive wheel comprises a rear wheel.

11. The vehicle controlling apparatus according to claim 5 , wherein the first drive wheel comprises a front wheel and the second drive wheel comprises a rear wheel.

12. The vehicle controlling apparatus according to claim 6 , wherein the first drive wheel comprises a front wheel and the second drive wheel comprises a rear wheel.

13. A vehicle controlling apparatus configured to control a first motor coupled to a first drive wheel and a second motor coupled to a second drive wheel, the first drive wheel and the second drive wheel being disposed at front and rear of a vehicle, the vehicle controlling apparatus comprising

circuitry configured to

determine whether an execution condition of a first slip control is satisfied, on a basis of an idling state of the first drive wheel,

control the first motor and maintain a slip rate of the first drive wheel at a predetermined first slip rate, in a case where the execution condition of the first slip control is determined as being satisfied,

determine whether an execution condition of a second slip control is satisfied, on a basis of an idling state of the second drive wheel,

control the second motor and maintain a slip rate of the second drive wheel at a predetermined second slip rate, in a case where the execution condition of the second slip control is determined as being satisfied, and

decrease a target torque of the second motor, in a case where the execution condition of the first slip control is determined as being satisfied and where the execution condition of the second slip control is determined as being unsatisfied.
