Abstract

The invention discloses a PEPS system field intensity calibration method and a PEPS system field intensity calibration system.The PEPS system field intensity calibration method is suitable for the PEPS system field intensity calibration system.The PEPS system field intensity calibration method comprises the steps: marking all test points of a vehicle body at equal intervals; establishing a test data table according to the test points in the action area of the plurality of low-frequency antennas; obtaining RSSI values of all test points; calculating a threshold value of the RSSI value; and determining the position of the intelligent key according to the threshold value of the RSSI value. The PEPS system field intensity calibration system comprises a plurality of low-frequency antennas, an intelligent key, a vehicle body controller and a display, wherein the low-frequency antennas, the intelligent key, the vehicle body controller and the display are electrically connected. The method has the advantages that the intelligent key is used as a measurement tool for PEPS system field intensity calibration, and the space inside and outside the vehicle is divided through the action area of the low-frequency antenna, so that the calibration workload is reduced, and the calibration speed is increased.

Description

technical field [0001] The invention relates to the technical field of automobile electronic control, in particular to a PEPS system field strength calibration method and a PEPS system field strength calibration system. Background technique [0002] With the development of automotive electronic systems, traditional mechanical keys and mechanical locks have been gradually replaced by keyless entry and start (Passive Entry Passive Start, PEPS) systems. When the key is within the valid range, the car owner pulls the door or presses the one-key start switch, the corresponding module will send an interrupt signal to wake up the main controller and start the entire communication process. The whole process does not require the use of a key to open the door or start the engine, adding a sense of fun and technology. In the current PEPS calibration method, there is no detailed description of how to accurately control the distance and control the effective area of ​​the PEPS. It is ba...
