A brake disc temperature determining method and apparatus, and a vehicle. The brake disc temperature determining method comprises: when a high-temperature re-clamping function is available, determining an initialization temperature of a brake disc according to a relationship between a brake disc temperature of a previous period and an ambient temperature; in a non-dynamic braking working condition, determining a raised temperature of the brake disc according to a wheel speed pulse and a wheel cylinder pressure, or in a dynamic braking working condition, determining a raised temperature of the brake disc according to a vehicle speed; determining a reduced temperature of the brake disc according to a relationship of temperature reduction of the brake disc along with the vehicle speed; and determining the temperature of the brake disc according to the initialization temperature and a difference between the raised temperature of the brake disc and the reduced temperature of the brake disc.
