What is the function of the car radar system?

The functions of automobile radar are as follows: front radar: the front radar probe is installed on the front bumper, and the probe radiates at an angle of about 45 degrees, searching for targets up, down, left and right.

The radar on the car is a rangefinder radar, which can detect the distance between the car body and obstacles and other vehicles, preventing the driver from hitting obstacles or other vehicles when reversing or moving the car.Parking radar is a common radar in cars. The principle of reversing radar is very simple.

The full name of the radar on the vehicle is "reversing anti-collision radar" or "parking auxiliary radar", which is used to monitor the distance between the body and other vehicles and obstacles.

How to use the car radar system?

1. The use of the car radar system is when the vehicle is in reverse gear, the function is activated to facilitate the driver's control of the reverse vehicle through image transmission to the vehicle.

2. Open the car door, step on the brake pedal of the vehicle, unstwear the key of the vehicle, run the engine, and idle. The instrument of the vehicle is turned on, and the whole vehicle has been turned on. Turn on the radar and press the reversing radar operation button on the left side of the vehicle's combination switch on the central console to turn on the reversing radar system.

3. If the car is equipped with a reversing radar, when reversing, the radar will automatically turn on after the reversing gear is hooked. If there is an obstacle at the rear of the car, the car's radar will sound an alarm, and the closer it is to the object, the faster the sound will be. The reversing radar is a sound prompt, and the reversing image has a display.

4. If the car is equipped with a reversing radar, when reversing, the radar will automatically turn on after hanging the reverse gear. If there is an obstacle at the rear of the car, the car radar will emit an alarm sound, and the closer it is to the object, the faster the sound will be. The reversing radar is a sound prompt, and the reversing image has a display.

5. In general, when the vehicle is in reverse gear (R gear), the reversing radar system is turned on. If the self-check is normal, the system will make a brief beep, indicating that the system is ready. When the reverse gear is joined, the parking assistance system will be automatically turned off. The reversing radar is a safety auxiliary device when a car is parked or reversing.

6. When using the Great Wall Cannon anti-collision radar system, there are the following ways to use it: press the icon button to start the ON mode with one click, and you can also turn on and off the anti-collision radar after the engine starts.When reversing, the anti-collision radar will turn on automatically. When the car enters p gear, the crash radar will automatically turn off.

What does the radar principle mean

1. The working principle of radar is to emit electromagnetic waves to irradiate the target and receive its echo, thus obtaining the distance, distance change rate (radial velocity) and athuth from the target to the electromagnetic wave emission point. , height and other information.

2. The principle of radar work: The radar FM transmitter causes sufficient electromagnetic induction kinetic energy, which is transmitted to the antenna through the receiving and sending switching switches. The antenna radiates this electromagnetic induction kinetic energy into the air, concentrates it in a narrow direction to produce a beam, and spreads it forward.

3. The transmitter of radar equipment passes through the antennaThe electromagnetic wave energy is projected in a certain direction of space, and the object in this direction reflects the electromagnetic wave encountered; the radar antenna receives this reflected wave, sends it to the receiving device for processing, and extracts some information about the object.

4. Radar is the transliteration of Radar in English, which comes from the abbreviation of radiodetectionandranging, which means "radio detection and ranging", that is, using radio methods to detect targets and determine their spatial positions. Therefore, radar is also known as "radio positioning". Radar is an electronic device that uses electromagnetic waves to detect targets.

5. The introduction of automotive radar is as follows: Automotive radar definition: Automotive radar, as the name implies, is a radar for cars or other ground motor vehicles. So it includes laser-based,Radars with different technologies such as ultrasound and microwave have different functions, such as detecting obstacles, predicting collisions, adaptive cruise control, and using different working principles.

6. The basic principle of radar is to detect targets through electromagnetic radiation. It emits electromagnetic waves to irradiate the target and receive its echo, thus obtaining the distance, distance change rate, azimuth, height, etc. from the target to the electromagnetic wave emission point. The principle of electromagnetic waves used by radar is very similar to that of sound waves.

What is the principle of car radar alarm

1. The working principle of car radar is: using the ultrasonic principle, the device on the car body probes the head to produce ultrasound, and reflects the sound waves after hitting the obstacle, so as to calculate the body and the obstacle. The actual distance of the object.

2. Automotive radar is also called reversing radar. The main principle of automotive radar is the ultrasonic principle. The full name of reversing radar is reversing anti-collision radar, also known as parking auxiliary device. It is a safety auxiliary device for parking or reversing, which is composed of ultrasonic sensors (commonly known as probes), controllers and monitors (or buzzers) and other parts.

3. Principle of radar: The radar FM transmitter causes sufficient electromagnetic induction kinetic energy, which is transmitted to the antenna through the receiving and sending switching switches. The antenna radiates this electromagnetic induction kinetic energy into the air, concentrates it in a narrow direction to produce a beam, and spreads it forward.

4. Therefore, it includes radar based on different technologies such as laser, ultrasound and microwave, which has different functions, such as detecting obstacles, predicting collisions, adaptive cruise control, and using different working principles.The function of car radar: reversing radar is a safety auxiliary device when a car stops or reverses.

5. It can indicate the condition of the obstacles around the driver with a noise or more directly, eliminate the confusion caused by the driver's up, down, left and right visits when parking, steering and starting the car, and assist the driver to eliminate the shortcomings of blind spots and blurred vision, and improve the safety factor of driving.

What is the use of dynamic radar cruise control system

1. The vehicle will automatically adjust the accelerator and brake through radar monitoring to maintain a safe distance from the vehicle in front. There is no need to repeatedly adjust the constant speed cruise, which can reduce driving. Staff fatigue, improve safety. There are four operation methods for radar cruise control: when the function is turned on, press the cruise control switch to start the cruise control.

2. Automatic cruise control (CruiseControl) is a control system that allows the driver to ensure that the car runs at a fixed pre-selected speed without operating the steering wheel, clutch and accelerator pedal.

3. Vehicle swing warning function. When the vehicle swings in the lane, the warning buzzer sounds and the information is displayed on the multi-information display to warn the driver. The lane maintenance function, which is linked with the full-speed dynamic radar cruise control function, provides the necessary assistance by operating the steering wheel to keep the vehicle in the current lane.

4. Intelligent automatic control system. Toyota radar cruise control is an intelligent automatic control system, known as adaptive cruise control. It is an upgraded version of the traditional cruise control system. Use the radar technology installed on the vehicle toMonitor the distance and speed of the vehicle in front, automatically adjust the accelerator and brake according to the information, and maintain a safe distance from the vehicle in front.

5. If the speed is higher than 30 kilometers per hour, the system can be turned on. The vehicle will preset the speed limit, automatically adjust the throttle and brake through radar monitoring, and maintain a safe distance from the vehicle in front. There is no need to repeatedly adjust the cruise control, which can reduce driver's fatigue and improve safety.
