  • Method and system for measuring and calibrating steering parameters of vehicle, medium and autonomous vehicle
    Patent number: 12060126
    Abstract: The present disclosure relates to a method and system for measuring and calibrating steering parameters of a vehicle, a medium and an autonomous vehicle. The method includes: calculating a steering angle of a front wheel of the vehicle corresponding to each sampling moment at a plurality of consecutive sampling moments respectively. The calculation process at each sampling moment includes: calculating a first calculated value based on a yaw velocity of the vehicle, a vehicle velocity and a wheelbase; calculating a second calculated value based on a vehicle velocity, a lateral acceleration of the vehicle and the wheelbase; calculating a third calculated value based on a rotating angle of the steering wheel and a steering gear ratio; and calculating a steering angle of the front wheel at a current sampling moment based on the first, second and third calculated value of the steering angle of the front wheel.
