Abstract

A vehicle electronic device, a method for protecting vehicle electronic device and a non-transitory computer-readable storage medium are disclosed. The vehicle electronic device includes a motherboard, a connection unit, and a protection assembly. The motherboard includes a data storage module. The connection unit is configured to capture an interface signal. The protection assembly includes a memory, a sensing component, and a processor. The memory stores a default unlocking parameter. The sensing component is configured to obtain a spatial sensing parameter when activated. In response to the connection unit losing the interface signal, the processor compares the spatial sensing parameter obtained within an unlocking time with the default unlocking parameter. In response to the spatial sensing parameter not matching the default unlocking parameter and exceeding the unlocking time, the processor generates a clear signal. The data storage module deletes at least a portion of data based on the clear signal.
