Vehicle speed control method and device

Abstract

A vehicle speed control method and a vehicle speed control device. The method comprises the following steps: monitoring traveling information of a vehicle during traveling of the vehicle; determining, according to the traveling information, whether the traveling environment is unfavorable for traveling of the vehicle; if yes, limiting the maximum rotation speed of the engine to a preset rotation speed, and limiting the maximum vehicle speed by limiting the maximum rotation speed; and if not, cancelling, if the maximum rotation speed of the engine is limited to the preset rotation speed, the limitation. The device comprises: a monitoring module used for monitoring traveling information of a vehicle during traveling of the vehicle; a determining module used for determining, according to the traveling information, whether the traveling environment is unfavorable for traveling of the vehicle; a speed limiting module used for limiting the maximum rotation speed of the engine to a preset rotation speed when it is determined that the traveling environment is unfavorable for traveling of the vehicle according to the obtained traveling information of the vehicle, and limiting the maximum vehicle speed by limiting the maximum rotation speed; and a canceling module used for canceling, when it is determined that the traveling environment is favorable for traveling of the vehicle according to the obtained traveling information of the vehicle, and the maximum rotation speed of the engine is limited to the preset rotation speed, the limitation. On the basis of different vehicle traveling environments, the method and device actively limits the maximum speed of a vehicle when the traveling environment is poor, and thus avoids potential safety hazards; moreover, the vehicle can be ensured to travel at a high speed when the traveling environment is good.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a vehicle speed control method and device. Background technique [0002] At present, the car is in different driving environments, whether it is driving on a mountain road or in heavy rain, or driving on a clear highway: the maximum speed that the vehicle can reach is the same. However, when the driving environment is not good, if the drivers drive at a high speed, it is very easy to cause traffic accidents and bring potential safety hazards to the driver of the vehicle and other drivers. If the maximum speed of the vehicle is set at the factory, then The vehicle cannot be driven at high speed when the driving environment is good. Contents of the invention [0003] The main purpose of the present invention is to provide a vehicle speed control method, which aims to limit the maximum speed of the vehicle when the driving environment is bad, avoid potential safety hazards, and ensure ...
