摘要： A method for controlling a braking system of a motor vehicle that includes a plurality of wheels, at least one electric motor as a drive, a service brake and a vehicle dynamic control system. The wheels can be braked by a deceleration torque applied by the service brake and at least partially by a deceleration torque (ME) applied by the electric motor where slippage which arises as a result of braking and/or of intervention by the vehicle dynamic control system is regulated at least primarily through adjustment of the deceleration torque applied by the electric motor. When necessary, a drive torque is applied to regulate slippage or to cause a locked wheel to rotate by the electric motor.

摘要： A vehicle control system may include a sensor network sensing vehicle attitude information and a controller operably coupled to the sensor network to determine, based on the vehicle attitude information, movement of a center of gravity of the vehicle relative to an axis of rotation of the vehicle. The controller may further determine a modification to a torque application of the vehicle based on the movement of the center of gravity of the vehicle relative to the axis of rotation of the vehicle.

摘要： A method includes identifying a path to be followed by an ego vehicle. The method also includes determining a desired yaw rate and a desired yaw acceleration for the ego vehicle based on the identified path. The method further includes determining a desired yaw moment for the ego vehicle based on the desired yaw rate and the desired yaw acceleration. In addition, the method includes distributing the desired yaw moment to multiple wheels of the ego vehicle such that the distributed desired yaw moment creates lateral movement of the ego vehicle during travel along the identified path. In some cases, the desired yaw rate and the desired yaw acceleration for the ego vehicle may be determined based on nonlinear kinematics of the ego vehicle, and the desired yaw moment for the ego vehicle may be determined based on a single-track dynamic model of the ego vehicle.

摘要： A method for controlling actuators acting on vehicle wheels of a motor vehicle comprises

ascertaining a force to be brought about on a reference point of the motor vehicle on the basis of driver specifications,
ascertaining wheel forces to be brought about on the vehicle wheels to implement the force to be brought about on the reference point of the motor vehicle by means of a first dynamic allocation by model-based predictive control (MPC),
ascertaining setpoint values for wheel parameters from the ascertained wheel forces, and
actuating the actuators of the motor vehicle so as to implement the setpoint values of the wheel parameters.

摘要： Systems and methods for general driving behavior of an autonomous vehicle are disclosed. In one aspect, an autonomous vehicle includes a trailer, at least one perception sensor, a non-transitory computer readable medium, and a processor. The processor is configured to estimate a grade of the roadway based on the perception data, provide a first control input to the autonomous vehicle based on the grade of the roadway, determine a response of the autonomous vehicle to the first control input based on the perception data, estimate a trailer load of the trailer based on the response of the autonomous vehicle to the first control input, and provide a second control input to the autonomous vehicle based on the grade of the roadway and the trailer load.

摘要： A method for restarting an engine of a vehicle stopped on a grade, comprising the steps of engaging a gear of a transmission through which the engine and wheels of the vehicle are drivably connected mutually, using brake pressure to engage wheel brakes and produce a road gradient wheel torque that holds the vehicle stationary on the grade, initiating an engine restart, operating the engine to produce wheel torque equal to or greater than the road gradient wheel torque, and releasing the brake pressure.
