Abstract

The invention relates to a strategy for reducing static power consumption of a polling function of a fuel vehicle, which relates to the field of automobiles. The strategy comprises the following steps of: S1, setting the driving current of an antenna to be between 280mA and 320mA when the polling function of a vehicle body controller is in an awakening waiting stage under dormancy; S2, shortening the time of awakening waiting stages of the polling function of the vehicle body controller under dormancy, with the awakening waiting stages being antenna driving stages, and a thorough dormancy stage being arranged between every two adjacent awakening waiting stages; and S3, setting the maximum operation time of the polling function, allowing the vehicle body controller to operate in the polling function mode within the time shorter than the maximum operation time, and the vehicle body controller to sleep thoroughly after the time longer than the maximum operation time, so that the static power consumption of the whole vehicle is reduced.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a strategy for reducing the static power consumption of the polling function of a fuel vehicle. Background technique [0002] see figure 1 The schematic diagram of the working mode of the polling function of the vehicle platform shown in sleep mode. In the wake-up waiting stage under sleep, it drives the main door handle antenna (ciol 1 pulse in the figure), the passenger door handle antenna (ciol 2 pulse in the figure), and the tailgate antenna (ciol 3 pulse in the figure) in sequence. ), and then completely sleep t pause (such as 1 second), then enter the wake-up waiting phase to work for one round, and then completely sleep again, and repeat the cycle like this. In this way, the total cycle of driving the antenna under sleep is the sum of the time between the wake-up waiting phase and the complete sleep phase, the wake-up waiting phase is the phase of driving the antenna, and the...
