A regenerative brake controller for controlling a value of regenerative braking torque to simulate engine braking torque. When the shift lever is in the D range, from a first control map which correlates the vehicle speed and the like with target braking torque or target deceleration, the controller reads the target braking torque or target deceleration corresponding to the vehicle speed immediately before the release of the accelerator pedal, and controls the vehicle components on the basis of the read target braking torque or target deceleration such that the regenerative braking torque corresponding to the engine braking torque is produced. When the shift lever is in the engine braking range, the controller detects the shift lever position in this range, determines the target braking torque or target deceleration by referring to the map, and on the basis of the vehicle speed and the like immediately before the release of the accelerator pedal and the shift lever position in the engine braking range, and controls the vehicle components according to the determined target braking torque or target deceleration such that the regenerative braking torque corresponding to the engine braking torque is produced. In connection with the regenerative braking torque corresponding to the engine braking torque, the vehicle drivability can be improved.
