Abstract
A method of controlling a coasting torque using an electric motor for a vehicle having the electric motor includes: determining a speed range to travel on a forward slope based on the current vehicle speed; determining a target speed within the speed range based on the coasting torque and a travel load depending on vehicle speed; and correcting a driving force of the electric motor in response to the determined target speed.
Claims19
A method of controlling a coasting torque using an electric motor for a vehicle having the electric motor, the method comprising:
- determining a speed range to travel on a forward slope based on a current vehicle speed;
- determining a target speed within the speed range based on the coasting torque and a travel load depending on vehicle speed;
- and
- correcting a driving force of the electric motor in response to the determined target speed.
A vehicle comprising:
- a driving motor configured to output a coasting torque when a driver does not accelerate or decelerate the vehicle;
- a first controller configured to:
- determine a speed range to travel on a forward slope based on a current vehicle speed,
- determine a target speed within the speed range based on the coasting torque and a travel load depending on vehicle speed, and
- correct a driving force of the driving motor in response to the determined target speed;
- and
- a second controller configured to control the driving motor in response to a torque command from the first controller.
