| description | The invention relates to the field of particulate filter control, and particularly discloses a DPF passive regeneration control method and system during gear sliding and a vehicle. Judging whether the vehicle is in a gear sliding state or not according to the vehicle running signal; if the vehicle is in the on-gear sliding state, the upstream temperature of the DPF is collected; and whether the upstream temperature of the DPF is smaller than a preset value or not is judged, if yes, the engine is controlled to enter a heat preservation mode to keep exhaust temperature, and if not, the upstream temperature of the DPF is continuously collected. When the vehicle slides with the gear, the engine is controlled to enter the heat preservation mode to keep the exhaust temperature, and the problem that the oil consumption and power of the vehicle are affected due to the fact that the exhaust temperature is reduced due to sliding with the gear and the DPF passive regeneration function cannot be triggered is solved.
