The invention discloses an electronic parking control device for a new energy automobile, which comprises a servo motor, a first-stage transmission device, a second-stage transmission device and a friction disc, and is characterized in that the second-stage transmission device is mounted on a second-stage transmission shaft, the second-stage transmission shaft is a hollow transmission shaft, a cavity of the second-stage transmission shaft is communicated with a cavity of the friction disc, and the friction disc is mounted on the second-stage transmission shaft. The other end of the second-stage transmission shaft is rotationally connected with a cooling mechanism used in cooperation with the friction disc. The input end of the first-stage transmission device is connected with the servo motor, and the output end of the first-stage transmission device is connected with the second-stage transmission device through a first-stage transmission shaft. In the working process, the cooling mechanism conveys cooling oil into the friction disc through the second-stage transmission shaft, the cooling oil is in full contact with the friction disc and then returns to the cooling mechanism, circulating cooling of the friction disc is achieved, the heat resistance of the friction disc is improved, and the driving safety of the new energy automobile is also improved.
