Steep slope slow descent control system based on electronic calipers

The invention discloses a steep slope slow descent control system based on electronic calipers. The steep slope slow descent control system comprises a control device, and a left brake disc, a right brake disc, an electronic parking caliper assembly, a sensor assembly and a steep slope slow descent switch which are connected with the control device, wherein the control device is configured to judge whether the current road condition of the vehicle is a steep slope condition or not according to the gradient; after it is judged that the current road condition of the vehicle is the steep slope road condition, the wheel signal is converted into the vehicle speed, and the current vehicle speed of the vehicle is obtained; the driving state information of the vehicle is collected, and after it is judged that the driving state information of the vehicle meets a preset condition for starting steep slope slow descent control, a control instruction is sent to adjust the first braking distance and the second braking dist
