Abstract
A method of controlling braking of a vehicle is provided. When a disconnector is disconnected and an auxiliary drive wheel is separated from a driving system, vehicle braking is performed with regenerative braking by a primary drive wheel motor during braking. Subsequently, the disconnector is connected based on a vehicle stability state, and then, braking is performed simultaneously on the auxiliary drive wheel and a primary drive wheel.
Claims17
A method of controlling braking of a vehicle having a first independent driving unit configured to drive front wheels, a second independent driving unit configured to drive rear wheels, and a disconnector that is installed in a driving shaft and makes and releases a connection for motive power transfer, the method comprising:
- determining, by a controller, a current vehicle stability index based on information collected within the vehicle;
- connecting or disconnecting, by the controller, the disconnector based on the determined vehicle stability index, and
- perform, by the controller, regenerative braking for all of the front and rear wheels of the vehicle, or for either the front wheels or the rear wheels based on a controlled state of the disconnector.
A system of controlling braking of a vehicle having a first independent driving unit configured to drive front wheels, a second independent driving unit configured to drive rear wheels, and a disconnector that is installed in a driving shaft and makes and releases a connection for motive power transfer, the system comprising:
- a memory configured to store program instructions;
- and
- a processor configured to execute the program instructions, the program instructions when executed configured to:
- determine a current vehicle stability index based on information collected within the vehicle;
- operate a vehicle controller to connect or disconnect the disconnector based on the determined vehicle stability index, and
- operate a brake controller to perform regenerative braking for all of the front and rear wheels of the vehicle, or for either the front wheels or the rear wheels based on a controlled state of the disconnector.
