Abstract

The invention relates to a method for displaying remainder driving ranges of hybrid electric vehicles. The method includes associating displayed fuel remainder driving ranges and displayed electricity remainder driving ranges with historical fuel consumption level and historical electricity consumption level of the vehicles when current driving ranges are shorter than first distances; disassociating the displayed fuel remainder driving ranges and the displayed electricity remainder driving ranges from the historical fuel consumption level and the historical electricity consumption level of the vehicles when the current driving ranges are longer than second distances. The invention further relates to a device for displaying the remainder driving ranges of the hybrid electric vehicles. The method is implemented by the device.

Description

technical field [0001] The present invention relates to the technical field of automobile control, and more particularly, to a method and a device for displaying the remaining driving range of a hybrid electric vehicle. Background technique [0002] With the continuous development of the automobile industry, the design of the dashboard of the car is more and more abundant, and the information that the driver can obtain from the dashboard of the car is also more and more abundant. Conventional instruments in general cars include speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging gauge, etc. In modern automobiles, most of the instrument displays are based on sensors, and the sensing device can change its resistance value, for example, according to the state change of the monitored object, and finally express or display it through the instrument. Usually, the most prominent thing on the instrument panel is the speedometer, which indicate...
