Abstract

The invention provides an adaptive cruising control method and device, and an electric vehicle. The method comprises the following steps: obtaining the vehicle driving state information of an electricvehicle and a target tracking vehicle; according to the vehicle driving state information, determining the target output torque of the electric vehicle; according to the target output torque, carrying out cruising control on the electric vehicle. By use of the method, the vehicle driving state information of an electric vehicle and the target tracking vehicle is obtained, and the electric vehicleis subjected to cruising control according to the target output torque, which is determined by the vehicle driving state information, of the electric vehicle. Therefore, in a vehicle following process, a driver regulates the power output of the vehicle to guarantee the driving and riding feeling of people on the vehicle on a premise that the vehicle is guaranteed to be safely driven, and the purposes of the dynamic traceability and the driving and riding comfort of the electric vehicle are realized.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an adaptive cruise control method and device and an electric vehicle. Background technique [0002] In the face of increasingly severe energy and environmental problems, energy-saving and new energy vehicles are becoming the hotspots of current research. As a type of energy-saving and new energy vehicles, pure electric vehicles have many advantages such as no exhaust emissions, high energy efficiency, low noise, and recyclable energy during driving. Therefore, vigorously developing pure electric vehicles is beneficial to energy security and environmental protection has great significance. [0003] Advanced Driver Assistant System (ADAS) has become a research hotspot in the field of intelligent transportation at home and abroad. Among them, the adaptive cruise control (Adaptive Cruise Control, referred to as ACC) system adjusts the output power of the vehicle by replac...
