Abstract: A fingerprint input method, apparatus, system and an electronic device are provided. The method includes: obtaining a fingerprint as a current fingerprint (S101); comparing the current fingerprint with a fingerprint stored in a fingerprint database (S102); storing, when it is determined that there is no fingerprint identical with the current fingerprint in the fingerprint database, the current fingerprint in the fingerprint database. It can be seen that before storing the obtained current fingerprint into the fingerprint database, it is firstly determined whether there is a fingerprint identical with the current fingerprint in the fingerprint database, and when it is determined that there is no fingerprint identical with the current fingerprint in the fingerprint database, the current fingerprint is stored in the fingerprint database, to avoid the occurrence of duplicate fingerprints in the fingerprint database, avoid the input of the duplicate fingerprints, and improve the user experience.

Abstract: The invention provides an automatic braking system and method and a vehicle. The automatic braking method comprises: entering an automatic braking process when a vehicle speed is less than a predetermined speed threshold value and a driver completely releases an accelerator pedal, wherein the automatic braking process comprises: detecting surrounding information by a sensing module; determining a target stop position based on the surrounding information, and determining a braking deceleration based on the target stop position; adjusting a motor and a braking system to slow down a vehicle at the predetermined braking deceleration and to stop the vehicle at the target stop position; and automatically activate an autohold system upon the vehicle stopping at the target stop position. The method and device according to embodiments of the invention can enable completely automatic braking and holding. The method and device according to embodiments of the invention can enable completely automatic braking and holding.
