The invention relates to the technical field of automobiles, and discloses an air-assisted hydraulic braking system and a new energy automobile. The air-assisted hydraulic braking system comprises a hydraulic braking device, an air-assisted device, a motor braking device and an electric control device. The hydraulic braking device comprises a front axle braking mechanism and a rear axle braking mechanism; the air-assisted device is respectively communicated with the front axle braking mechanism and the rear axle braking mechanism through air pressure pipelines so as to respectively provide airpressure driving force for hydraulic braking of the front axle braking mechanism and the rear axle braking mechanism; the motor braking device is used for motor braking of the automobile; and the electric control device is electrically connected with the air-assisted device and the motor braking device, so that the air pressure driving force of the air-assisted device acting on the front axle braking mechanism and the rear axle braking mechanism can be regulated, and the braking force of the motor braking device can be regulated. The automobile braking system has the following advantages: theair-assisted device and the motor braking device can be cooperatively controlled to achieve automobile braking, so the energy recovery efficiency and the endurance mileage are improved, and the automobile braking system is suitable for new energy automobiles of 3.5 tons or above.
