Patent number: 9002609Abstract: A vehicle brake control system includes a regenerative braking control component, a frictional braking control component, a calculating component and a controlling component. The regenerative braking control component controls a regenerative braking device to provide a regenerative braking torque.

Patent number: 8670914Abstract: A vehicle brake control system has a braking detector and a braking controller. The braking detector determines whether a braking operation in a vehicle is within an initial braking stage based on a control condition of a frictional braking system. The braking controller performs initial braking stage control during the initial braking stage by controlling a regenerative braking system to provide a limited braking torque and the frictional braking system to provide a supplemental braking torque, the combination of which provides a target braking torque. The braking controller performs subsequent braking control when the initial braking stage ends to provide an increased regenerative braking torque and a lower supplemental braking torque as the target braking torque.Type: GrantFiled: April 22, 2011Date of Patent: March 11, 2014Assignee: Nissan Motor Co., Ltd.Inventors: Noriaki Fujiki, Keigo Ajiro, Takuya Higuchi
