The disclosure discloses a method and an apparatus for simulating a vehicle. The detailed implementation includes: determining, by a tire dynamics module, a tire translational force at a current moment based on a control instruction issued by an upper planning module and motion data of a vehicle body and a tire normal load outputted by a vehicle body dynamics module at a previous moment; and determining, by the vehicle body dynamics module, motion data of the vehicle body and a tire normal load at the current moment based on the control instruction and the tire translational force at the current moment, the motion data of the vehicle body at the current moment being used for vehicle simulation, and the tire normal load at the current moment being used to determine a tire translational force at a next moment.

Method and apparatus for simulating vehicle, and medium

A method, device and apparatus for processing a control parameter, and a storage medium are provided. The method includes: acquiring first information input to a control system; acquiring second information output after the first information is processed by the control system; obtaining a first parameter characteristic for characterizing a system parameter, according to the first information and the second information; obtaining a second parameter characteristic for adjusting the control parameter, according to the first parameter characteristic and a corresponding relation between the system parameter and the control parameter; and adjusting the control parameter according to the second parameter characteristic. Thus, an adaptive adjustment of the control parameter based on the variation of the scene is realized, and the parameter adjustment efficiency is improved.

Method, device and apparatus for processing control parameter, and storage medium

A method and a device for eliminating a steady-state lateral deviation and a storage medium are provided. The method includes: determining whether a vehicle travels on a straight road; collecting a lateral deviation value of the vehicle in a case that the vehicle travels on a straight road; determining whether the vehicle has the steady-state lateral deviation based on the collected lateral deviation value; and compensating the steady-state lateral deviation of the vehicle in real time based on the collected lateral deviation value in a case that the vehicle has the steady-state lateral deviation. The vehicle has the steady-state lateral deviation may run steadily, a direction of the vehicle is more accurate, self-driving safety and efficiency are improved, the sense of leftward and rightward swaying brought by a continuous deviation rectification method in the conventional art is effectively eliminated, and self-driving stability is improved.
