摘要： A vehicle may include an active ride comfort tuning system that reactively and/or proactively alters a parameter of a system of the autonomous vehicle to mitigate or avoid interruptions to ride smoothness. For example, the comfort tuning system may alter a parameter of a drive system, suspension, and/or a trajectory cost function. The comfort tuning system may alter the parameter based at least in part on detecting and/or receiving a comfort indication, determined based on sensor data, user input, or the like.

摘要： A method is provided to control a power steering device and an adaptive damping system of a motor vehicle. The power steering device makes available a mechanical steering angle range that is limited by steering stops. The adaptive damping system makes available a variable damping force. The damping force of the adaptive damping system is increased and a maximum achievable steering angle is simultaneously increased in case a steering stop is reached.

摘要： The invention concerns a method for estimating an International Roughness Index (IRI) of a road or road segment. comprising a preliminary step (1) and an International Roughness Index estimation step (10). The preliminary step (1) comprises collecting (2) values of vehicle tire damping and stiffness coefficients (Ct, Kt) and collecting (3) vehicle vertical acceleration values (Azvehicle) measured on vehicles driven at a constant speed along road segments to which known international roughness index values or known road profiles (profiler) are associated, as well as vehicle geo-referencing data and speed data indicative of the given constant speed associated with the measured vertical acceleration values (Azvehicle).

摘要： In a control system, a first estimator estimates, as a first controlled force, a force being applied to a controlled object. A second estimator estimates, as a second controlled force, a force being transferred to the controlled object. An external force estimator estimates, as an external force, a force being exerted on the vehicle as the vehicle runs. A dynamics estimator estimates, based on the first controlled force, the second controlled force, and the external force, a value of a parameter that represents the dynamics of the controlled object. A compensator compensates for at least one of the first controlled force and the second controlled force such that the value of the parameter is within a preset target range.

摘要： A travel instruction information generation device has a vehicle information acquisition unit, a travel instruction information generator, and a correction information generator. The vehicle information acquisition unit acquires vehicle information representing a specific state of a vehicle. The travel instruction information generator generates travel instruction information with which the vehicle performs self-driving by using three-dimensional map information. The correction information generator generates, on the basis of the vehicle information, correction information for correcting the travel instruction information.

摘要： A method of controlling the stability of a vehicle. The method comprises acquiring an actual value of a vehicle stability parameter and determining a difference between the actual parameter value and a target value of that stability parameter. The method further comprises applying a damper intervention threshold to the difference between the actual and target parameter values, the damper intervention threshold representing a magnitude of the difference between the actual and target parameter values at which damper intervention may be utilized to mitigate a potential over-steer or under-steer condition. The method still further comprises predicting the occurrence of an over-steer or under-steer condition when the damper intervention threshold is exceeded.
