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.

    本发明涉及汽车技术领域,公开了一种气助力液压制动系统及新能源汽车,气助力液压制动系统包括液压制动装置、气助力装置、电机制动装置和电控装置。液压制动装置包括前轴制动机构和后轴制动机构;气助力装置通过气压管路分别与前轴制动机构和后轴制动机构连通,进而分别为前轴制动机构和后轴制动机构的液压制动提供气压驱动力;电机制动装置用于电机制动汽车;电控装置分别与气助力装置及电机制动装置电连接,进而够调控气助力装置分别作用于前轴制动机构和后轴制动机构的气压驱动力,且还能够调控电机制动装置的制动力。其优点为:能协同控制气助力装置及电机制动装置实现汽车制动,提高能量回收效率和续航里程,适用于3.5吨以上的新能源汽车。
