GPS-Car Navigation System
It is a radio navigation and positioning system based on 24 positioning satellites around the world, providing 3D location, 3D speed, and other information all over the world. The positioning principle of GPS is: the user receives the signal transmitted by the satellite, acquires parameters such as the distance between the satellite and the user, clock correction and atmospheric correction, and determines the position of the user through data processing. At present, civil GPS positioning accuracy can be less than 10m. The special features of GPS have long attracted the attention of the automotive community. When the United States announced the opening of a part of the GPS system after the Gulf War, the automobile industry immediately took advantage of this opportunity to invest funds to develop a car navigation system to locate the car. And guide display, and quickly put into use.
The automobile GPS navigation system consists of two parts: one part is composed of GPS receivers and display equipments installed in the automobile workers; the other part is composed of a computer control center, and the two parts are contacted by positioning satellites. The computer control center is authorized and organized by the motor vehicle management department. It is responsible for observing the dynamics and traffic conditions of the designated monitored vehicles at any time in the jurisdiction.
Therefore, a complete GPS car navigation system has at least two major functions: one is the car trail monitoring function, as long as the encoded GPS receiver is installed in the car, the car can travel through the computer control center's electronic map no matter where it travels. It indicates where it is located (currently many operating vehicles are equipped with this system); the other is the driving guide function, the owner of the area of ​​the transport line electronic map is stored on the disc, as long as the car's navigation system into On the CD-ROM, the location of the vehicle's area and the current traffic status will be displayed on the screen. You can enter the desired destination, pre-program the best driving route, and accept the instruction from the computer control center to select the car. The route and direction.
Reversing radar
The reversing radar is a safety auxiliary device when the vehicle is parked or reversing, and can inform the driver of the obstacles in the surroundings with sound or more intuitive display, and cancels the driver's parking, reversing and starting the vehicle. Confused and help the driver clear the flaws of the blind spots and blurred vision, improve driving safety. Now that there has been a visual parking sensor, the driver can no longer really see the situation around the car without having to listen to the dripping sounds.
Fully automatic, four-zone independent air conditioning
With automatic thermostat function, air conditioning systems with different temperatures and wind speeds can be realized according to the needs of the occupants in the four areas including the driver's seat, the front passenger's seat, the left rear seat, and the rear right seat (ie, what people often say as bosses).
Multifunction steering wheel
On the steering wheel, a steering wheel that can control buttons including audio, car phones, gears, etc. is arranged so that the driver can control many electronic devices in the vehicle without leaving the steering wheel, which greatly improves the safety and convenience of driving.
Cruise control
Cruise control is used to control the constant speed driving of the car. Once the car is set to cruise, the fuel supply of the engine is controlled by the computer. The computer will continuously adjust the fuel supply according to the road conditions and the driving resistance of the car. The car always stays at the set speed without having to manipulate the throttle. At present, the cruise control system has become the standard equipment for mid-to-high-class cars.
Automatic parking
The car can be automatically parked at the correct parking position. The system can collect image data and distance data from the surrounding object to the car body, and transmit it to the central processor through the data line; and after the analysis and processing by the CPU, the car can be obtained. The current location, target location and surrounding environmental parameters are based on the above parameters to make an automatic parking strategy and convert it into an electric signal; after the vehicle strategy control system receives the electric signal, it makes a car's travel according to the instructions such as the angle, Direction and power support controls.
KEYLESS-GO function
As long as the car key is on the body, you will automatically open the door lock and pull the button on the top of the bar to start the car. The whole process does not need to touch the key.
