Method for the automated guidance of a vehicle, journey control unit and vehicle
A method for automated guidance of a vehicle along a specified setpoint trajectory at an actual speed, wherein the setpoint trajectory includes geometric trajectory variables, the method including ascertaining an actual deviation of the vehicle from the setpoint trajectory and outputting the ascertained actual deviation and generating manipulated variables such that the vehicle, in the case of automated control of a drive system and/or a braking system and/or a steering system of the vehicle, moves closer to the setpoint trajectory. The method also includes ascertaining whether an undesirable driving state is present when the vehicle moves closer to the setpoint trajectory, wherein the undesirable driving state is ascertained from the specified setpoint trajectory based on the geometric trajectory variable, and, if the presence of the undesirable driving state is identified, automatically controlling the vehicle based on generated stability variables and/or adapting the setpoint trajectory.
Vehicle integrated control device and vehicle integrated control method
A vehicle integrated control device improves ride comfort and prevents the onset of motion sickness. The vehicle integrated control device acquires a target momentum of a control axis related to a driving task of the vehicle and generates a first motion parameter and a second motion parameter different from the first motion parameter that is based on the first motion parameter to optimize a sensitivity index. A limit generation unit generates a motion limit amount of the second motion parameter based on the first motion parameter and an operation range of an actuator, a final target generation unit that corrects the second motion parameter based on the motion limit amount, and an operation amount assignment unit that determines an operation amount of an actuator based on the first motion parameter and the second motion parameter corrected by the final target generation unit.
METHOD FOR ATTENUATING INTERFERENCE IN THE MEASUREMENT OF A TILT ANGLE OF A VEHICLE
A method for attenuating interference in the measurement of an angle of sideways tilt of a motorized two-wheeled vehicle including an electronic control unit configured to compute an angle of sideways tilt of the vehicle from the measurements of a tilt sensor. The method includes: reception of the value of the speed of the vehicle measured by the speed-measuring module; reception of the number of revolutions per minute of the engine; computation of the ratio between the received speed value and the received number of revolutions per minute; comparison of the ratio between the received speed value and the number of revolutions per minute with an attenuation interval; if the ratio is outside the attenuation interval, computation of the tilt angle without attenuation; if the ratio is within the attenuation interval, computation of the tilt angle with attenuation.
METHOD AND CONTROL SYSTEM FOR OPERATING A SELF-DRIVING VEHICLE
A method for operating a self-driving vehicle is provided. The method includes specifying a lateral dynamics requirement for controlling the lateral dynamics of the self-driving vehicle along a route. The lateral dynamics requirement is communicated to a steering control device for controlling steering kinematics of the self-driving vehicle. The method checks whether the communicated lateral dynamics requirement satisfies a lateral dynamics criterion for the operation of the self-driving vehicle, and communicates a brake command to stop the self-driving vehicle depending on a checking result resulting from the checking step.
