The invention discloses a low-power-consumption automobile RKE remote controller and a method for lowering power consumption. The method comprises the steps that the automobile RKE remote controller is set to have a long data transmitting mode and a short data transmitting mode; the RKE remote controller is driven to enter the long data transmitting mode and to transmit long data, a BCM controller of an automobile is started for learning and decrypting the long data transmitted by the automobile RKE remote controller, and the automobile RKE remote controller stores the long data after decryption is effective and enters the daily mode; the RKE remote controller is driven to enter the short data transmitting mode and to transmit short data, the BCM controller receives the short data and decrypts the short data, and an operation request is executed when decryption is effective; the RKE remote controller comprises a long data transmitting module, a short data transmitting module, a switching module and a display module. The short data transmitting module is set to transmit short data, so that opening and closing of automobile doors and a trunk are achieved, the number of digits of transmitted data is decreased, data transmission power consumption is lowered, and the service life of a battery inside the remote controller is prolonged.
Description
technical field [0001] The invention relates to car remote control technology, in particular to a low-power car RKE remote controller and a method for reducing power consumption. Background technique [0002] The car RKE system specifically sends a series of high-frequency pulse digital signals to the BCM controller installed in the car through a wireless transmitter in the remote control. After the signal is decoded, the controller controls the transmission mechanism to open and close the door or the trunk. In the United States and Japan, the carrier frequency of the wireless generator is 315MHz, while in Europe it uses 433.92MHz (ISM frequency band). Japan's RKE system uses frequency shift keying FSK modulation, and most other countries use amplitude shift keying ASK modulation. Its carrier amplitude is modulated at two levels. In order to reduce power consumption, the value of the low level is usually close to 0, so an on-off keying (OOK) modulation is generated. [000...
