Abstract

The invention provides a vehicle control method and apparatus. The vehicle control method includes the steps: receiving a starting instruction of a driving assistance function; acquiring visibility data of the vehicle by using an environmental information collecting module; acquiring a preset safe driving distance of the vehicle according to the visibility data; acquiring the current distance between the vehicle and a front vehicle; and controlling the traveling speed of the vehicle by adjusting the corresponding state of an acceleration module and a braking module according to the comparisonrelationship between the current distance and the preset safe driving distance. The vehicle control method solves the problem that in the prior art, the user misjudges the environment in the foggy day, thus causing the vehicle speed to be too high and being prone to traffic accidents.

Description

technical field [0001] The invention relates to the field of automobiles, including a vehicle control method and device. Background technique [0002] With the sharp increase in the number of cars and the widespread occurrence of smog weather, traffic accidents caused by smog weather occur from time to time. [0003] In the prior art, the traffic accident rate is mainly reduced by reminding the driver to slow down in smoggy days. However, after reminding the user to slow down, the user still needs to subjectively judge the environmental conditions and control the vehicle speed. Achieve the effect of reducing the accident rate. [0004] However, since the foggy weather will affect people's senses, the driver is prone to misjudgment and the speed of the vehicle is too fast. Therefore, the existing method cannot be an effective method for preventing user accidents in hazy weather. Contents of the invention [0005] In view of this, because the prior art reminds the user to ...
