Abstract

The invention provides a vehicle-mounted altitude monitoring device and a vehicle-mounted altitude monitoring method. The device comprises a central control module, a sensor module connected to the central control module, a power supply module for supplying power to the device and a display module; the sensor module acquires an air pressure signal and a temperature signal of a position where the device is positioned, and inputs the signals to the central control module; the central control module performs temperature compensation on the temperature signal and performs filtering processing on the air pressure signal respectively to calculate a relative altitude height value of the position where a vehicle is positioned; and the value is displayed by the display module. The vehicle-mounted altitude monitoring method is high in accuracy and sensitivity, and the vehicle-mounted altitude monitoring device is intelligent, and simple in structure, low in cost and small in volume.

Description

【Technical field】 [0001] The invention relates to the technical field of automotive electronics, in particular to a vehicle-mounted altitude monitoring device and method. 【Background technique】 [0002] In recent years, domestic automobile sales have continued to grow. Among all automobile market segments, SUV products are the most eye-catching. In the entire SUV market, urban SUVs that take into account comfort and off-road performance have become the absolute must in the entire SUV market. main character. On many occasions, off-road jeeps or the above-mentioned urban SUVs often drive at high altitudes or areas with large vertical terrain differences. During this process, real-time information about the relative altitude and direction of the vehicle when driving is of great significance to the driver. quite significant. [0003] Most of the existing altimeters are mechanical, which have the disadvantages of low sensitivity, large error, high failure rate and unintuitive d...
