Method for controlling traffic lane monitoring assistance function using steering system of motor vehicle, involves calculating assistance torque, and adding base angle regulation torque and assistance torque to obtain set point torque

摘要

The method involves establishing a set point steering angle using a lane detection unit i.e. lane monitoring camera (32), and measuring a real steering angle in the event of risk of leaving a traffic lane. Base angle regulation torque is calculated from an angular difference between the set point angle and the real angle, using a proportional-derivative or digital regulation system. Assistance torque is calculated by multiplying a value of steering wheel resistance torque with gain values. The calculated torques are added to obtain set point torque. Independent claims are also included for the following: (1) a steering system comprising a camera (2) a motor vehicle including a steering system.
