Abstract
Provided is an early warning method of trapping in a vehicle. The early warning method includes: a current bearing value of a seat is stored as an initial value when unlocking of a vehicle door is detected, a weight difference is obtained by performing a subtraction operation between the current bearing value of the seat and the initial value when locking of the vehicle door is detected, and a trapping alarm signal is given when the weight difference is greater than or equal to a preset first weight threshold. An early warning device of trapping in a vehicle and a computer readable storage medium are further provided. With the adoption of the embodiment of the present disclosure, a false alarm as a result of the article fixed on the seat of the vehicle in the conventional art may be effectively solved, and an early warning for the child or the pet staying in the vehicle may be effectively implemented at the same time.
