Two-wheeled vehicle Bluetooth keyless unlock and start solution

1. Program overview:

Electric bicycles have received strong support from the government for their economy, ease of use, energy saving, emission reduction and noise reduction, and have become the best choice for working-class household second-wheel mobility tools. Ordinary electric vehicles require the use of a car key and remote control to start, but some high-end smart electric vehicles have appeared on the market, which can be started and locked with one touch using a mobile phone APP. So how is this achieved?



Shengrun Technology's Bluetooth keyless unlocking and starting solution for two-wheeled vehicles can help you realize that a mobile phone can play an electric car without a key and a remote control. The car mainly installs the corresponding mobile phone APP, then turns on the mobile phone's Bluetooth function, turns on the sensor switch, and the mobile phone connects to the electric car through Bluetooth. When the user approaches the car, the electric car will automatically unlock, and it will automatically start after getting in the electric car, and the user will leave the car At a certain distance, the electric vehicle is automatically locked. After the first pairing, subsequent users can unlock the lock without taking out the mobile phone.



The Bluetooth keyless unlock and start system connects the mobile phone APP and the electric vehicle through Bluetooth, and intelligently upgrades the electric vehicle, so as to realize the remote control of the vehicle, automatic unlocking, one-key car search, intelligent anti-theft, power detection, OTA wireless upgrade, etc. Function. Bluetooth non-inductive keyless unlocking and starting subversively simplifies the entire unlocking, starting, and locking process of two-wheel electric vehicles, greatly improving the owner's experience.

2. Program features:

Mobile APP virtual key: One-click start, get vehicle information, both Android and IOS platforms can be used, support OAD upgrade, key authorization, and locate the distance between the mobile phone and the vehicle.
