1. Q The overlook guidance mode occurs when vehicle is under REVERSE gear and the ultrasonic sensor can not trigger it A There may be a connection error between the ultrasonic signal and mainframe Ask for the technician for assistance Q Why the generated overlook image has deficient area The generated image possesses two black areas in the bottom left and bottom right part A It is the inevitable result after the image transform the generated black image areas are the blind spots of the original image If the user can not adapt to such representation he she can ask the technician to rearrange the installation Q If the user can not obtain the accurate installation height gt inclination how to adjust the appropriate parameters A If user can not capture the accurate parameters an alternative system installation by parking grid 1s also available Try to maneuver the vehicle and make the grid line of the parking space parallel to the generated trajectory Then the adjustment can be achieved based on the grid line on the ground Q Why the image based mode switch sometimes fail A The image based mode switch is based on the image processing techniques to estimate the possible obstacles to determine the time of mode switch To reduce the possibility of misjudgment a learning mechanism is proposed Therefore when the image based mode switch is activated by the drive shift the gear stick at the REVERSE position he she has to wait2.
