1. An electric vehicle comprising:
- a front motor for driving right and left front wheels;
a rear motor for driving right and left rear wheels;
a target torque determiner for determining a target torque of the front motor and a target torque of the rear motor, based on at least a displacement amount of an accelerator operation member operated by a driver; and
a motor controller for controlling the front motor and the rear motor to cause the front motor to output the target torque and the rear motor to output the target torque, wherein when one of the front wheels or the rear wheels slip when all the wheels are driven by the front motor and the rear motor, the target torque determiner decreases the target torque of one of the front motor or the rear motor for driving the one of the front wheels or the rear wheels which are slipping and increases the target torque of the other of the front motor or the rear motor for driving the other of the front wheels or the rear wheels which are not slipping.

13. An electric vehicle comprising:
-
a front motor for driving right and left front wheels; a rear motor for driving right and left rear wheels; a target torque determiner for determining a target torque of the front motor and a target torque of the rear motor, based on at least a displacement amount of an accelerator operation member operated by a driver; and a motor controller for controlling the front motor and the rear motor to cause the front motor to output the target torque and the rear motor to output the target torque, wherein when one of the front wheels or the rear wheels slip when all the wheels are driven by the front motor and the rear motor, the target torque determiner increases the target torque of one of the front wheels or the rear wheels for driving the other of the front wheels or the rear wheels which are not slipping.

14. An electric vehicle comprising:
-
a front motor for driving right and left front wheels; a rear motor for driving right and left rear wheels; a target torque determiner for determining a target torque of the front motor and a target torque of the rear motor, based on at least a displacement amount of an accelerator operation member operated by a driver; and a motor controller for controlling the front motor and the rear motor to cause the front motor to output the target torque and the rear motor to output the target torque, wherein when one of the front wheels or the rear wheels slip when all the wheels are driven by the front motor and the rear motor, the target torque determiner changes a ratio of torque allocation of the target torque of the front motor and the target torque of the rear motor by decreasing the target torque of one of the front motor or the rear motor for driving the one of the front wheels or the rear wheels which are slipping and increasing the target torque of the other of the front motor or the rear motor for driving the other of the front wheels or the rear wheels which are not slipping.
