Problems solved by technology

[0003] However, when there are changes in road conditions, such as bumpy roads, crosswinds from the side, or slopes ahead, the existing adaptive cruise control system cannot accurately determine the road condition information in a timely manner, causing the vehicle to drive at an inappropriate speed, and the vehicle does not drive enough. Safety, or when the cruise system encounters a slight change in road condition information, it will be turned off directly, and the operating conditions are too harsh

Abstract

The invention provides a self-adaptive cruising device used for an electric vehicle. The self-adaptive cruising device comprises a self-adaptive cruising controller, a vehicle speed sensor, a gyroscope, a crosswind detector and a controller, wherein the self-adaptive cruising controller is used for setting vehicle cruising speed according to an operation instruction of a driver; the controller is used for controlling torque output of a motor of the electric vehicle according to the set vehicle cruising speed; the gyroscope is used for detecting jitter amplitude in the vertical direction of the vehicle in real time; the crosswind detector is used for detecting size of crosswind force of the position at which the vehicle is located in real time; the self-adaptive cruising controller further responds to data information of the gyroscope and the crosswind detector to regulate the cruising speed in a self-adaptive mode and sends a response signal to the controller; and the controller is further set to regulate torque output of the motor of the electric vehicle according to the response signal of a regulating part. The self-adaptive cruising device can be used for timely and accurately judging a current road condition, regulating vehicle speed according to the road condition information, and ensures the electric vehicle to safely and stably travel.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an adaptive cruise device for electric vehicles. Background technique [0002] Adaptive cruise is a function often used by drivers during long-distance driving. Its function is to automatically maintain the speed of the vehicle without stepping on the accelerator pedal after it is turned on at the speed required by the driver, so that the vehicle can run at a fixed speed. With this device, after driving on the expressway for a long time, the driver no longer needs to control the accelerator pedal, which reduces fatigue, reduces unnecessary speed changes, and saves fuel. [0003] However, when there are changes in road conditions, such as bumpy roads, crosswinds from the side, or slopes ahead, the existing adaptive cruise control system cannot accurately determine the road condition information in a timely manner, causing the vehicle to drive at an inappropriate speed, a...
