Title:
METHOD AND DEVICE FOR DATA COLLECTION WHEN RAISING ALARM
Document Type and Number:
WIPO Patent Application WO/2017/120840
Kind Code:
A1
Abstract:
A method and device for data collection when raising an alarm. The method comprises: presetting multiple braking distances corresponding to vehicle speeds (S101); when a vehicle is traveling, acquiring the vehicle speed and the headway (S102); when the headway is equal to or less than the braking distance corresponding to the vehicle speed, issuing alarm information and transmitting technical usage data to a data collecting end preset by a manufacturer (S103). This allows the vehicle to automatically determine, on the basis of the current vehicle speed and headway, whether a brake needs to be engaged at any given moment so as to prevent rear-ending or colliding with the vehicle in front and also to alert a driver that the headway is too short, allows the driver to determine whether a lane change is required on the basis of actual driving conditions, in addition, reduces the stress of driving for a novice driver, and, at the same time, facilitates the manufacturer in collecting a use state of a related technique in a timely and effective manner.
