Abstract
A vehicle may include a hydraulic braking device configured to hydraulically brake at least one of front and rear wheels of the vehicle, a drive motor configured to provide driving force to the at least one of the front wheels and the rear wheels, an accelerator pedal sensor detecting an operation of an accelerator pedal, and a controller electrically connected to the accelerator pedal sensor, wherein the controller is configured to generate a hydraulic braking torque through a cooperative control with the hydraulic braking device depending on an amount of regenerative braking torque while the vehicle coasts.
Claims18
A vehicle, comprising:
- a hydraulic braking device configured to hydraulically brake at least one of front and rear wheels of the vehicle;
- a drive motor configured to provide a driving force to the at least one of the front wheels and the rear wheels;
- an accelerator pedal sensor configured for detecting an operation of an accelerator pedal;
- and
- a controller electrically connected to the accelerator pedal sensor;
- wherein the controller is configured to generate a hydraulic braking torque through a cooperative control with the hydraulic braking device depending on an amount of regenerative braking torque while the vehicle coasts, and
- wherein the controller is further configured to determine an amount of braking energy based on a hydraulic braking force provided to wheel brakes of the vehicle by the hydraulic braking torque and a moving distance of the vehicle, and release the hydraulic braking torque based on the determined amount of the braking energy.
A method of controlling a vehicle including a hydraulic braking device for hydraulically braking at least one of front and rear wheels and a drive motor for providing driving force to the at least one of the front and rear wheels, the method comprising:
- determining, by a controller, a regenerative braking torque while the vehicle coasts;
- generating, by the controller, a hydraulic braking torque through a cooperative control with the hydraulic braking device depending on an amount of regenerative braking torque during the coasting;
- and
- determining, by the controller, an amount of braking energy based on a hydraulic braking force provided to wheel brakes of the vehicle by the hydraulic braking torque and a moving distance of the vehicle;
- and
- releasing the hydraulic braking torque based on the determined amount of the braking energy.
