In one example, terminal is positioned using GPS module.Assuming that corresponding first range of the first setting condition is [80%, 50%), it is assumed that second impose a condition corresponding second range be [50%, 20%), it is assumed that third, which imposes a condition, to be corresponded to Third range be [20%, 0).

When GPS module is in consecutive tracking state, the battery of acquisition terminal current residual electricity and user are used first Habits information estimates information about power of the user after half an hour.If information about power is sufficient after half an hour, such as larger than 80%, then the adjustment of any positioning strategy can not be done, GPS module consecutive tracking is continued to use.If after estimating half an hour Information about power is, for example, less than 80% but is greater than 50%, can requry the users whether need to enable power saving positioning at this time not counting abundance Mode, and inform that this may lose certain precision, if user agrees to, enters power saving station-keeping mode and otherwise continue to make With continuous GPS positioning.If it is lower to estimate the information about power after half an hour, such as less than 50% but be higher than 20%, then can to Family asks whether to need to enable deep power-saving station-keeping mode, and informs that this may lose certain precision, need to travel with caution, such as Fruit user agrees to, then enters deep power-saving station-keeping mode and otherwise continue to use continuous GPS positioning.If after estimating half an hour Information about power is extremely low, is such as lower than 20%, then inquires whether the user needs to enter extreme power saving station-keeping mode, and inform user's wind Danger, and (such as control screen brightness) inconvenient for use that may cause then enter extreme power saving positioning mould if user agrees to Otherwise formula continues to use GPS positioning.

It wherein, can be by reducing GPS module location frequency, in conjunction with sensing data, map number under power saving station-keeping mode According to realizing co-located.Wherein, the power consumption of inertial sensor is more much lower than GPS module, therefore after entering battery saving mode, GPS frequency can be lowered to 10s is primary, and can switch to dead reckoning in 9s of the centre without GPS positioning, dead reckoning The motion state variation (i.e. velocity information) in per second is measured by inertial sensor, and can be according to last location data Moving distance information is calculated with velocity information.But the moving distance information of reckoning may cause position error, therefore combinable Map number matches position, obtains corresponding location data.When using GPS module positioning next time, GPS mould is exported The corresponding location data of block, and corrected using the position in the location data to map, and be initial with this position Subsequent dead reckoning is carried out, so not only ensure that positioning continuity and precision, but also reduce power consumption.
