Abstract

The invention discloses a hybrid electric vehicle LCD instrument device based on a CAN. A single chip microcomputer is adopted by the device to serve as a core control unit, and various kinds of information of a hybrid electric vehicle in the running process can be obtained through a CAN bus network; an LCD display module is used for digital display of information, and a non-contact type infrared induction module is adopted to control page switching of the LCD display module and periodically emits and receives infrared rays through an infrared emission tube and an infrared receiving tube; when fingers are not in the induction area, the infrared rays are transmitted through glass, and the infrared receiving tube does not receive infrared signals; when the fingers are in the induction area, the infrared rays are reflected through the glass, and the infrared receiving tube receives the infrared signals; and the control unit judges whether page turning is needed or not through the signals of the infrared receiving tube. The device is integrated with an external brightness induction module, backlight of the LCD display module is automatically adjusted, and the clear and gentle vision effect is achieved.

Description

technical field [0001] The invention relates to a CAN bus-based comprehensive information indication device for a hybrid electric vehicle, in particular to a CAN-based LCD instrument device for a hybrid electric vehicle. Background technique [0002] The instrument on the car is an important way for the driver to understand the routine operating parameters of the vehicle. At present, the known car instrument is mainly composed of discrete indicating units. Small, bulky, low cost performance, and unsatisfactory visual effects, etc., especially for dynamic information such as energy status during driving of hybrid vehicles, there is no effective and intuitive indication method. In addition, the operation buttons on the instrument panel are all mechanical buttons, which have a short service life and are relatively cumbersome to maintain. Contents of the invention [0003] In order to solve the current problem that the operating information of hybrid electric vehicles is indi...
