Abstract
A vehicle includes: a plurality of wheels; a motor for providing a driving force to the plurality of wheels based on electrical energy stored in a battery; a modulator for controlling a number of rotations of the motor; and a controller for controlling the modulator based on a first control value at a coasting control and controlling the modulator based on a second control value when a wheel slip occurs in a safety control.
Claims18
A vehicle comprising:
- a plurality of wheels;
- a motor for providing a driving force to the plurality of wheels based on electrical energy stored in a battery;
- a modulator for controlling a number of rotations of the motor;
- and
- a controller for:
- controlling the modulator based on a first control value for controlling the motor to rotate with a first magnitude torque at a coasting control,
- when a wheel slip occurs in a safety control, controlling the modulator based on a second control value for controlling the motor to rotate with a second magnitude torque other than zero, and
- when the wheel slip dissipates, controlling the modulator so that the motor rotates by gradually raising a magnitude of torque from the second magnitude torque to the first magnitude torque based on a preset time and a difference between the first magnitude torque and the second magnitude torque.
A control method of a vehicle, which includes a motor for generating a driving force to wheels based on electrical energy stored in a battery, the control method comprising steps of:
- determining, by a controller, a safety control based on a state of a road surface;
- controlling, by the controller, the motor based on a first control value for controlling the motor to rotate with a first magnitude torque, at a coasting control;
- when a wheel slip occurs in the safety control, controlling, by the controller, the motor based on a second control value for controlling the motor to rotate with a second magnitude torque other than zero;
- and
- when the wheel slip dissipates, controlling, by the controller, the modulator so that the motor rotates by gradually raising a magnitude of torque from the second magnitude torque to the first magnitude torque based on a preset time and a difference between the first magnitude torque and the second magnitude torque.
