Abstract

The invention discloses an energy saving method for an intelligent key based on a PEPS system; the energy saving method comprises the steps: after a control chip in the intelligent key receives a radio-frequency signal or an interrupt signal, the intelligent key is controlled to have a sleep mode switched into a work mode, and according to the radio-frequency signal or the interrupt signal, corresponding operation is implemented; and after the corresponding operation is implemented, the control chip controls the intelligent key to have the work mode switched into the sleep mode. The invention also discloses the intelligent key; the mode switching of the intelligent key is controlled by the control chip, the intelligent key can be in a sleep mode when the radio-frequency signal or the interrupt signal are not received, and the electric quantity consumption of the intelligent key can be effectively reduced, so under a condition of ensuring that the intelligent key normally works, the electric quantity consumption of the intelligent key is effectively saved, and the power consumption of the intelligent key is reduced.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an energy-saving method for a smart key based on a PEPS system and the smart key. Background technique [0002] With the rapid development of technology, (Passive Entry&Passive Start, keyless entry and keyless start) control technology is becoming more and more mature, and has become a standard product of many economical models. The PEPS system smart key uses advanced radio frequency identification technology to realize functions such as entering the car without pressing the remote control and starting the engine with one button. PEPS has more intelligent access control management and higher anti-theft performance, and has become the mainstream of automotive electronic anti-theft systems. [0003] At present, the smart key is usually powered by a battery. In the prior art, the smart key needs to be in the working mode all the time and consumes a lot of power. Therefore, how to prolong...
