Abstract

The invention discloses a self-adaptive cruise control method and device and an automobile. The self-adaptive cruise control method comprises the steps of obtaining a position signal of the automobile; identifying a road danger level according to the position signal of the automobile; and carrying out self-adaptive cruise control on the automobile according to the road danger level. The self-adaptive cruise control method has the advantages that construction facilities or construction personnel on roads are accurately monitored on the basis of guaranteeing the self-adaptive cruise function; road faults and dangers can be found in time; the safety of the automobile can be improved; and the driving comfort is improved by using a controller to carry out smooth processing on the torque.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an adaptive cruise control method, device and vehicle. Background technique [0002] Adaptive cruise system ACC is an intelligent automatic control system, which is developed on the basis of the existing cruise control technology. During the driving process of the vehicle, the sensor installed on the vehicle continuously detects the relative speed and time distance information of the vehicle in front and the vehicle in front. The braking system and the motor control system act in coordination to properly brake the wheels and reduce the output power of the motor so that the vehicle always maintains a safe distance from the vehicle in front. [0003] When the self-vehicle is performing adaptive cruise following, the lane of the self-vehicle is closed due to the road construction ahead. At this time, if the vehicle in front realizes the dangerous situation later, after it turns to ...
