The invention discloses an optimization method and system for the problem of too slow yaw response of vehicle steering input. The method comprises the following steps: acquiring vehicle reaction conditions after steering input; and judging the occurrence of the problem according to the acquired vehicle reaction conditions after steering input At the specific position of the body; obtain the vehicle roll condition, vehicle speed and vehicle steering input response speed change conditions; obtain the analysis of the problem according to the vehicle roll condition, vehicle speed and vehicle steering input response speed change conditions Characteristic type: According to the obtained vehicle yaw response too slow problem occurs in the specific position of the body and the obtained vehicle input yaw response too slow problem analysis characteristic type, obtain the vehicle steering input yaw response too slow problem occurs in the specific part of the part. Location. The optimization method for the problem that the vehicle steering input yaw response is too slow provided by the present invention can quickly check and locate the problem point of the too slow yaw response, which is beneficial to solve the problem quickly and accurately.
Description
technical field [0001] The present invention relates to the technical field of vehicle yaw response, in particular to an optimization method and system for the problem that vehicle steering input yaw response is too slow. Background technique [0002] In vehicle development, there is often a problem that the yaw response of the steering input is too slow, the response to the steering input is slow, and the whole vehicle is dull and sluggish. [0003] The prior art discloses a yaw stability control method with nonlinear characteristics of a vehicle, including a reference model, a tire lateral force and cornering stiffness processor, an MPC controller, and a Carsim vehicle model. The reference model is used to determine the expected car yaw rate; the tire lateral force and cornering stiffness processor is used to determine the tire's cornering angle, lateral force and cornering stiffness; the CarSim car model is used to output the actual motion state information of the car , ...
