AI Technical Summary

Technical Problem

Existing adaptive cruise control systems for electric two-wheelers suffer from problems such as delayed braking force, insufficient safety, unsuitability for curves, complex exit procedures, and lack of user takeover judgment.

Method used

The electrical system, composed of sensors and controllers, responds to torque requests through energy recovery, and, in conjunction with the ABS control module, provides auxiliary braking when braking force is insufficient. It also identifies curve scenarios and adjusts vehicle speed to achieve adaptive cruise control.

Benefits of technology

It improves the braking response speed and safety of electric two-wheelers, adapts to different driving scenarios, simplifies the adaptive cruise control mode exit process, and enhances the user experience.

Abstract

An electric two-wheeled vehicle (100) and an adaptive cruise method therefor. The method comprises: a radar (162a) acquiring surrounding environment information; in an adaptive cruise mode, on the basis of data fed back by the radar (162a) and a vehicle speed of the present vehicle, estimating an acceleration of the present vehicle and an acceleration of a preceding vehicle serving as a target vehicle, so as to calculate a relative acceleration of the present vehicle and the preceding vehicle, thus acquiring a required speed variation value; and sending a speed variation requirement to a controller (163) by means of a CAN bus or other communication modes, such that the controller (163) calculates a torque requirement, and when deceleration is required, a traction system (15) responding to the calculated torque requirement by means of energy recovery, etc. A response speed of an electrical signal is significantly greater than that of a mechanical structure, thereby reducing a braking delay. An active braking function is replaced by energy recovery, and it is unnecessary to use an ABS having an active boosting function, thereby saving on vehicle space.
