Multifunctional onboard information system

Abstract

The invention discloses a multifunctional onboard information system simultaneously provided with four groups of ultrasonic range-finding chips for monitors the information around the four sides of avehicle body. A matrix display displays the information so that a driver can understand the distance from the four sides of the vehicle body to obstacles in real time. When the vehicle body is too close to the obstacles, an acousto-optic alarm can be given to remind the driver to pay attention. Further, an infrared receiving chip is additionally provided in order to synchronously receive an infrared signal from an electronic key. Thus, the multifunctional onboard information system can be triggered and controlled at a distance of dozens of meters. Once the multifunctional onboard information system is triggered, a temperature signal is acquired by a temperature detection module. In case of over-low engine temperature, the engine is automatically turned on for warming up the vehicle body. When a user gets in the vehicle, the car has been warmed up for a certain period of time, thereby reducing the warm-up time and saving time for the vehicle owner. The multifunctional onboard information system has the advantages of various functions, precise control and good practicality.

Description

technical field [0001] The invention relates to a vehicle-mounted system, in particular to a multifunctional vehicle-mounted information system. Background technique [0002] With the continuous progress of social economy and the rapid development of high technology, cars have become an ideal means of transportation for people in daily work and life. However, many novices will encounter such problems when they first learn to drive. The front of the car cannot be seen from the driver's seat, especially for drivers who are not tall. At the same time, many novices who are not familiar with driving cannot accurately grasp the distance from the front, rear, left, and right obstacles. In congested cities, they often encounter red lights and traffic jams. In situations such as crowded parking spaces, the driver needs to accurately grasp the distance between the vehicle and obstacles.

[0002] With the continuous progress of social economy and the rapid development of high technology, cars have become an ideal means of transportation for people in daily work and life. However, many novices will encounter such problems when they first learn to drive. The front of the car cannot be seen from the driver's seat, especially for drivers who are not tall. At the same time, many novices who are not familiar with driving cannot accurately grasp the distance from the front, rear, left, and right obstacles. In congested cities, they often encounter red lights and traffic jams. In situations such as crowded parking spaces, the driver needs to accurately grasp the distance between the vehicle and obstacles. At present, there are few electronic devices on the market that can simultaneously monitor obstacles around the vehicle body, resulting in many scratch accidents.

At the same time, drivers all know that the car needs to be warmed up for a certain period of time when it is turned on in winter, so as to reduce the viscosity of the oil and increase the service life of the engine. However, for many office workers or people who are in a hurry, there is almost no warning hot time, thus causing greater damage to the engine
