The invention provides a constant-speed cruise control system and method based on a vehicle-mounted navigation system. The constant-speed cruise control system comprises a loudspeaker host unit, an engine control unit, an ABS controller, a constant-speed cruise control switch and a constant-speed cruise control setting switch. The ABS controller, the constant-speed cruise control switch and the constant-speed cruise control setting switch are connected to the loudspeaker host unit. The loudspeaker host unit is connected to the engine control unit and has a navigation positioning function. The engine control unit stably maintains the vehicle speed within the cruising speed range according to the set cruising speed, detected vehicle speed information and navigation positioning information. According to the constant-speed cruise control system and method, the cruising vehicle speed is set by directly utilizing the limited vehicle speed of a road, and therefore it is ensured that a vehicle can not be driven in an overspeed manner; and gradient information of the road section where the vehicle is located is sufficiently considered during vehicle speed maintaining so that constant-speed control can be more stable and comfortable, the intelligent control level of the constant-speed cruise control system can be greatly improved, and modern vehicle development requirements can be met.
