A steering control device suppresses response delay to stabilize a behavior of a vehicle during turning braking. The steering control device includes a steer-by-wire system that controls an actuator that detects displacement of a steering angle when a steering wheel is steered and operates a turning mechanism that turns a turning wheel separated from the steering wheel based on a detection result; a vehicle yaw angle detector; a steering angle detector; a turning state detector that detects a turning state of the vehicle based on the yaw angle; a braking state detector that detects a braking state of the vehicle; and a yaw angle controller that controls the actuator to suppress a yaw angle deviation before and after braking when the turning state of the vehicle is detected by the turning state detector and when the braking state of the vehicle is detected by the braking state detector.

A number of variations may include a method including pre-charging at least a portion of a vehicle brake system.

A system including a computer having a processor and a memory. The memory includes instructions executable by the processor to, upon actuating movement of a steering element of a vehicle, measure a torque applied to the steering element in a direction opposite the actuated movement. In response to a determination that the torque is less than a predetermined threshold, the processor actuates a component of the vehicle.

The disclosure relates to a steering system assembly for a vehicle, for example a steer-by-wire system, in which, in particular, detection devices and implementation devices for a steering request are mechanically decoupled from one another, having: a first steering system for providing a steering function, which is designed to be autonomous and/or has a first energy supply; a second steering system for providing a first fallback level for the steering function, which is designed to be autonomous and/or has a second energy supply; and a third steering system for providing a second fallback level for the steering function, in particular through selective wheel braking.

An aircraft nose landing gear assembly is disclosed including two wheels, motors, brakes, and a controller. The wheels are separated by a steering axis and independently rotatable about a rotation axis in a rotation direction. The motors and brakes are each arranged to selectively engage a respective wheel. The motors and brakes supplement and resist rotation of the respective wheel in the rotation direction, respectively. On the basis of an indication to the controller of rotation of the two wheels in the rotation direction, the controller is arranged to: cause one motor to engage its respective wheel and supplement rotation, and cause the brake associated with the other wheel to engage the other wheel and resist rotation. Engagement of the motor and brake causes the wheels to pivot about the steering axis during a turning event.

A one-side brake control system and method perform distribution of torques between front and rear wheels. The one-side brake control system includes a target steering angle input unit to which a target steering angle of a driver or a controller of an autonomous vehicle is input when a steering system fails, an integrated Electronic Control Unit (ECU) configured to calculate a target moment of the vehicle according to the target steering angle input through the target steering angle input unit and calculate brake torques of a one-side front wheel and a one-side rear wheel of the vehicle based on the target moment, and a braking ECU configured to control one or more braking actuators of the one-side front wheel and the one-side rear wheel of the vehicle according to the brake torque of the front wheel and the rear wheel transmitted from the integrated ECU to perform one-side brake.

A system and method for modifying one or more vehicle control systems in a target vehicle prior to a collision with an approaching vehicle are disclosed. The system and method include detecting that a collision is imminent and controlling one or more vehicle control systems automatically to change the impact duration and/or location, depending on the type of collision detected.

A vehicle control method includes early detection of an unstable driving state of a vehicle at least using an actual variable and a setpoint trajectory; wherein it is ascertained during early detection whether the unstable driving state is understeering of the vehicle or oversteering of the vehicle; and in response to the early detection: definition of a steering angle correction for a setpoint steering angle, wherein the steering angle correction includes a steering-angle limitation of an actual steering angle that can be provided if the unstable driving state is understeering of the vehicle, and wherein the steering angle correction includes a countersteering angle directed counter to the setpoint steering angle if the unstable driving state of the vehicle is oversteering; and steering of the vehicle using the steering angle correction. A vehicle control system, a vehicle and a computer program product are configured to perform the method.

A steering control device is configured to control a steering of a vehicle having at least one piloted actuator associated with a system for steering a wheel of the vehicle and a piloted actuator associated with a decoupled braking system at a wheel of the vehicle. The steering control device includes at least one control unit. The control unit is configured to recover at least one value characteristic of the travel of the vehicle and to issue a control instruction to the at least one piloted actuator according to the recovered value(s). The control unit includes a calculation module in which a model of a lateral dynamic behavior of the vehicle frame is implemented. At least one specific physical quantity of the lateral dynamic behavior is expressed according to the specific drifts of each set of front wheels and rear wheels of the vehicle.

A driving dynamics system for a vehicle may include a primary control unit for detecting and/or generating steering commands and braking commands; a brake system having first and second electrohydraulic pressure supply units; four hydraulically actuable wheel brakes of respective wheels; electrically actuable brake pressure adjustment valves; and an electric steering actuator for actuating at least one axle. The driving dynamics system may implement a steering command during normal operation to actuate at least one of the pressure supply units and the steering actuator and/or, to implement a braking command during normal operation, to actuate at least the second pressure supply unit and at least the brake pressure adjustment valves for a wheel-specific pressure adjustment and, in a fault case, to actuate at least the first pressure supply unit and at least the brake pressure adjustment valves for a wheel-specific pressure adjustment.
