Abstract
Official abstract text for this publication.
A vehicle control method includes: determining a target yaw rate of a vehicle when the vehicle meets a rear wheel turning control condition; acquiring a first yaw rate of the vehicle when a front wheel of the vehicle turns at a front-wheel maximum turning angle and a rear wheel of the vehicle turns at a rear-wheel maximum turning angle in a turning direction opposite to the front wheel, and a second yaw rate of the vehicle when the front wheel turns at the front-wheel maximum turning angle and the rear wheel does not turn; determining a magnitude relationship between the first yaw rate and the target yaw rate, and a magnitude relationship between the second yaw rate and the target yaw rate, respectively; and controlling the rear wheel of the vehicle according to whether the magnitude relationships meet a preset control condition.
First claim
Opening claim text (preview).
What is claimed is: 1 . A vehicle control method, comprising: determining a target yaw rate of a vehicle in response to determining that the vehicle meets a rear wheel turning control condition; acquiring a first yaw rate of the vehicle in response to determining that a front wheel of the vehicle turns at a front-wheel maximum turning angle and a rear wheel of the vehicle turns at a rear-wheel maximum turning angle in a turning direction opposite to the front wheel, and a second yaw rate of the vehicle in response to determining that the front wheel turns at the front-wheel maximum turning angle and the rear wheel does not turn; determining a magnitude relationship between the first yaw rate and the target yaw rate, and a magnitude relationship between the second yaw rate and the target yaw rate, respectively; and controlling the rear wheel of the vehicle according to whether the magnitude relationships meet a preset control condition, wherein the method further comprises: determining that the magnitude relationships meet the preset control condition in response to determining that the target yaw rate is less than the first yaw rate and the target yaw rate is greater than or equal to the second yaw rate. 2 . The vehicle control method according to claim 1 , wherein controlling the rear wheel of the vehicle according to whether the magnitude relationships meet the preset control condition comprises: obtaining a turning direction of the front wheel of the vehicle, and performing a turning control on the rear wheel of the vehicle at a preset rear wheel turning angle in a direction opposite to the turning direction of the front wheel, in response to determining that the magnitude relationships meet the preset control condition; and not performing turning control on the rear wheel of the vehicle, in response to determining that the magnitude relationships do not meet the preset control condition. 3 . The vehicle control method according to claim 1 , further comprising: determining that the magnitude relationships do not meet the preset control condition in response to determining that the target yaw rate is greater than or equal to the first yaw rate, or the target yaw rate is less than the second yaw rate.
