The invention discloses an intelligent vehicle longitudinal-vertical cooperative control system and method for comfort and energy conservation. The longitudinal-vertical cooperative control system comprises a vehicle sensor module, a road surface unevenness information preview module, a vehicle state information estimation module, a communication module, a vehicle longitudinal-vertical cooperative control module, an electromagnetic suspension system, a control module of the electromagnetic suspension system, a power system and a control module of the power system. The longitudinal-vertical cooperative control method comprises the following steps: determining suspension control parameters at a future moment according to a front road surface type and a road surface unevenness level obtained by preview, and calculating a maximum comfortable speed based on the front road surface unevenness and the corresponding suspension control parameters; on the basis, the vehicle driving efficiency and the energy efficiency are comprehensively considered, the optimal longitudinal acceleration is calculated, and longitudinal-vertical cooperative control is achieved through suspension control parameter switching and running speed adjustment at the future moment. Cooperative control over the longitudinal vehicle speed and the vertical suspension can be achieved, and the riding comfort of the intelligent vehicle in the unmanned driving process is improved in an energy-saving mode.
