what’s the use?
system can automatically help you park your car and even pulled out of the parking space without playing their own direction.

Advantages:
Automatic parking for the novice is a very convenient configuration, it is for the veteran to save a lot of effort.
· avoid the cut rub occurred due to not pay attention to parking.

Myth:
· Even with automatic parking assist system can not replace the driver’s attention, It remains to be seen confirmation.
* Not all parking into the gap can be automatically, the need to reserve more space before operating conditions meet the system requirements.
Automatic parking is not entirely without any operation by the driver, or the need to control the brake and the prompts respective engaged gear, when the driver human intervention (e.g., the direction of play), the automatic parking system It will immediately stop.

Did you know?
· After the automatic parking system is activated, the general is to find a suitable parking space, not all parking spaces are available for automatic parking. Today, many systems have not only supported parallel parking, and also enables pour garage.
· mode of operation and the conditions of each brand models enable automatic parking system are not the same. When
· leaves, waste or ice cover along the road, the parking steering assistance system may be difficult to identify the curb. Further leaves and snow can also cause severe scattering of the reflected ultrasonic signal, so that the system may result in errors received weak ultrasonic echo.
If there is an obstacle warning column size smaller space on the other, the system may not recognize as valid and to the parking space, the vehicle speed decreases help improve recognition system may empty small size articles sex.
· In the automatic parking process the driver will have voice prompts collision may occur.

Technical principle:
around the periphery of the vehicle radar sensor measures the distance between itself and the surrounding objects angle, the operation flow then calculated by the onboard computer to adjust the rotation of the steering wheel with the vehicle speed.
The system includes a data acquisition system environment, the central processor of the vehicle, and policy control systems, environmental data acquisition system comprising an image acquisition system and a vehicle distance detection system, the image data may be acquired from the vehicle body and surrounding objects distance data to the central processor and transmitted through the data line.
The central processor may analyze collected data processing, obtained current position, target position and environmental parameters around the car, made according to the above automatic parking strategy parameter, and converts it into an electrical signal .
After receiving the vehicle electrical control system strategy, to control aspects of the vehicle such as traveling angle and direction according to the commands until the parking spaces.

reading:
different automatic parking systems use different methods to detect objects around the vehicle. Some four weeks in the automotive front and rear bumpers fitted with a sensor, which can act as both transmitters, can also act as a receiver. The sensor sends a signal, when the signal is outside the vehicle collides with an obstacle will be reflected. Then, the vehicle computer will use the time required for its received signal to determine the position of the obstacle. Other systems use a camera mounted on the bumper or radar to detect an obstacle. But the end result is the same: the car detects that the vehicle has been parked, the size of the parking space and the distance from the side of the road, and then the car into the parking space.
