Personalized autonomous vehicle ride characteristics
Systems and method are provided for controlling a vehicle. In one embodiment, a method includes: obtaining ride preference information associated with a user, identifying a current vehicle pose, determining a motion plan for the vehicle along a route based at least in part on the ride preference information, the current vehicle pose, and vehicle kinematic and dynamic constraints associated with the route, and operating one or more actuators onboard the vehicle in accordance with the motion plan. The user-specific ride preference information influences a rate of vehicle movement resulting from the motion plan.

A method is for operating a vehicle which has actuators for influencing a driving behavior of the vehicle. The method includes sensing a setpoint for the driving behavior, in particular a steering angle set by a driver, and depending on the setpoint for the driving behavior, a first pilot control variable is determined using a model for the vehicle. Depending on the first pilot control variable, a second pilot control variable is determined using at least two partial models for the driving behavior of the vehicle, which differ due to the use of at least one of the actuators. Depending on the first pilot control variable and depending on the second pilot variable, a first setpoint for a first actuator is determined. The first setpoint is output in order to actuate the first actuator.
