Electric vehicle active speed-limiting control system based on navigation map

Abstract

The invention discloses an electric vehicle active speed-limiting control system based on a navigation map. The electric vehicle active speed-limiting control system comprises an active speed-limitingcontrol device, a vehicle control system, a vehicle computer system, a motor controller, a BeiDou Navigation Satellite System (BDS) and a radar speedometer, wherein the vehicle computer system selects a low value from first speed-limiting information and second speed-limiting information to form speed-limiting information of a current position; when the active speed-limiting control device is triggered, the vehicle control system outputs a speed request command by comparing vehicle speed information with the speed-limiting information; and the motor controller adjusts the rotational speed ofa driving motor according to the speed request command. The electric vehicle active speed-limiting control system based on the navigation map disclosed by the invention realizes active control of thevehicle running speed based on the navigation map built in a vehicle computer, and at the same time enables a driver to select whether to allow a vehicle to implement the active speed-limiting controlaccording to the need.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to an active speed limit control system for electric vehicles based on a navigation map. Background technique [0002] Now that the road network is becoming more and more developed, and the performance level of vehicles is also constantly improving, drivers will speed unknowingly, violating traffic rules, drivers face speeding penalties, and thus increase the probability of traffic accidents. Existing vehicles generally use instruments for speeding alarms, which can only serve as prompts and cannot be actively intervened and controlled. [0003] The patent application number is 201610397663.0, and the subject name is the invention patent of electric vehicle and its active speed limit control method and system. Although an active speed limit control method is proposed, the system can only drive under limited road conditions, but in special cases, The speed of t...
