The invention discloses a parking braking reclamping control method which comprises the following steps: S1, detecting whether a vehicle is in a driving state at present, if the vehicle is in the driving state at present, executing a step S2, and if the vehicle is in a parking state at present, executing a step S3; s2, updating an environment coefficient x based on a recursive least square method; and S3, entering a re-clamping mode, determining the current clamping force and the temperature of the brake disc based on the environment coefficient x at the current moment, and determining a re-clamping strategy based on the temperature Tn of the current brake disc. The environment coefficient and the online learning environment coefficient are provided, when the vehicle is parked, the currently learned environment coefficient is used for calculating the clamping force under high-temperature re-clamping, then the temperature of the brake disc is obtained, the re-clamping opportunity and the re-clamping frequency are matched based on the temperature, the high-temperature re-clamping effect is improved, and the high-temperature re-clamping efficiency is improved. And the man-vehicle safety is improved, and the service life of a parking braking system is prolonged.
