Xiaomi’s upcoming EV, the Modena, is expected to launch by the end of this year. Ahead of the launch, a new Xiaomi patent has been spotted that reveals a technology for automatic crash detection and emergency contact alerts.

The patent describes a system that uses three modules to assess the severity of an accident: a Get module, a Determine module, and a Communication module. The Get module collects status information about the vehicle, such as battery failure, circuit failure, airbag deployment, and wheel detachment. The Determine module then uses this information to classify the accident as Level 1 or Level 2.

Level 1 accidents include minor damage, such as a cracked windshield or damaged bumper. In the event of a Level 1 accident, the system will send a text message with the accident information to the vehicle’s preset emergency contact.

Level 2 accidents include more serious damage, such as vehicle rollover, oil tank leak, or wheel detachment. In the event of a Level 2 accident, the system will send a notification message to the preset emergency contact and make an emergency call to the emergency service center.

The system will reject all calls from emergency and non-emergency contacts while the emergency call is in progress. Once the emergency call is over, the system will wait for an emergency callback. All calls from non-emergency contacts during this period will be rejected. All calls from the emergency contact or emergency service center will be routed through the terminal device associated with the vehicle.

The system will also start a timer when the emergency rescue wait starts after coordinating with the emergency service center. If the rescue is not done within the stipulated waiting time, another call will be made to the preset emergency contact.

This advanced vehicle crash and emergency contact alert system is expected to feature in the Xiaomi Modena EV.  The Modena is also expected to come with BYD LFP and CATL Qilin batteries, a Snapdragon 8295 processor, and more.
