AI Technical Summary
⚠Technical Problem
Existing in-vehicle head units experience frequent wake-ups due to proximity detection, leading to power waste and reduced service life, and delayed wake-up times when entering a low-power state.
⚗Method used
Utilizing a first and second positioning module to detect distance signals from a key terminal, sending locking, sleep, wake-up, and unlocking signals based on preset ranges and conditions to manage the head unit's power states efficiently.
🎯Benefits of technology
This approach reduces power consumption, extends the service life of the in-vehicle head unit, and ensures quick wake-up times by optimizing power management based on real-time distance detection and user scenarios.

Abstract
The present application discloses an in-vehicle head unit quick start method, an electronic device, a storage medium, and a program product, and the in-vehicle head unit quick start method includes: acquiring, by a first positioning module and / or a second positioning module, a first distance signal between a key terminal and a vehicle; determining a first distance according to the first distance signal, and sending a locking signal if the first distance is in a first preset range; acquiring, by the second positioning module, at least one second distance signal between the key terminal and the vehicle; and sending a sleep signal if the second distance signal satisfies a preset condition. In the present application, a distance between the key terminal and the vehicle is detected by a positioning module, whether the distance is in a set preset range is determined, and change state data of the distance between the key terminal and the vehicle is acquired in real time, and then an operation stage and an operation mode is determined based on a personnel state and a movement scenario, and an instruction is sent to operate the vehicle control apparatus, which effectively solves a technical problem of frequent wake-up of the in-vehicle head unit in the prior art, which easily leads to a waste of power, service life reduction, and wake-up delay.
