VEHICLE CONTROL METHOD AND SYSTEM

WIPO Patent Application WO/2018/227933

A1

A vehicle control method and system, the method comprising: acquiring a maximum deceleration which a road surface that a current vehicle is on is capable of providing; acquiring first data, comprising a relative speed and/or time interval between a target vehicle and the current vehicle; the target vehicle being a vehicle in front of the current vehicle which is closest to the current vehicle; according to the first data, determining whether the target vehicle is in a braking state; when the target vehicle is in a braking state, acquiring a target deceleration required by the current vehicle; according to the maximum deceleration and the target deceleration, deciding whether there is a rear-ending risk for the current vehicle; when there is a rear-ending risk, controlling the current vehicle to brake and turn so as to decelerate at the maximum deceleration. The present method uses a maximum deceleration a road surface a current vehicle is on can provide and a required target deceleration as a basis for determining whether there is a rear-ending risk, solving the problem in current ACC control processes of not considering road surface adhesion conditions, leading to poor control results and low safety.
