METHODS AND SYSTEMS FOR A HYBRID ELECTRIC VEHICLE

The invention relates to a hybrid electric vehicle (1), which has at least one internal combustion engine, at least one electric regenerative braking system and at least one electric operated oil heating device (2). The internal combustion engine has at least one lubricating oil system (3) equipped with at least one oil pan, at least one oil filter (4) and at least one oil pipeline (5) capable ofconnecting the oil filter (4) to the oil pan. In order to improve the heating of the lubricating oil of a lubricating oil system (3), and to improve the energy efficiency of the hybrid electric vehicle (1), the oil heating device (2) forms a part of the oil pipeline (5) and is electrically connected to the regenerative braking system. 本发明涉及一种混合动力电动车辆(1)，其具有至少一个内燃机、至少一个电动再生制动系统和至少一个电动操作的油加热装置(2)，其中该内燃机具有至少一个润滑油系统(3)，该润滑油系统配备有至少一个油盘、至少一个机油滤清器(4)和将机油滤清器(4)连接到油盘的至少一个机油管路(5)。为了改善润滑油系统(3)的润滑油的加热，并以这种方式提高混合动力电动车辆(1)的能效，油加热装置(2)形成机油管路(5)的一部分并电连接到再生制动系统。
