The invention discloses an active collision avoidance method for a blind area of an intelligent automobile sensor, and relates to the technical field of driving safety. The method comprises the steps: acquiring blind area characteristic information of the vehicle-mounted sensor, and establishing a blind area motion state equation; according to the motion state of the blind area, establishing a vehicle longitudinal active collision avoidance safety distance model, and calculating the safety distance; acquiring the relative speed and the relative distance between the vehicle and the blind area of the vehicle-mounted sensor and the driving target of the intelligent vehicle, and controlling the speed of the intelligent vehicle through the electronic control unit, so that the intelligent vehicle safely passes through the blind area of the vehicle-mounted sensor. According to the active collision avoidance method for the intelligent automobile in the sensor blind area, the dangerous collision working condition can be avoided in time when the automobile passes through the sensor blind area, and the driving safety coefficient is remarkably improved.
