The invention relates to a hill starting auxiliary system for a hybrid power commercial vehicle, and solves the problem that the current commercial vehicle is easy to slip on a slope when starting on the slope. Comprising a braking main valve, a service braking air cylinder, a drain valve, a composite braking air chamber, a differential relay valve, a two-position three-way electromagnetic valve, a first pressure switch, a second pressure switch, a parking braking air cylinder, a gradient detection module and a gearbox controller. The braking main valve is connected with the differential relay valve; the parking brake air reservoir is connected with the two-position three-way electromagnetic valve and the differential relay valve, and the two-position three-way electromagnetic valve is communicated with the atmosphere; the differential relay valve is connected with the composite brake chamber; a second pressure switch is connected between the two-position three-way electromagnetic valve and the differential relay valve; a first pressure switch is connected between the braking main valve and the differential relay valve; the gearbox controller is connected with the two-position three-way electromagnetic valve, the gradient detection module, the first pressure switch and the second pressure switch. According to the invention, transient slope parking of the whole vehicle on the slope can be realized.
