An independent steering control apparatus may include: a processor configured to analyze whether wheels are abnormal, on the basis of turning angles of the respective wheels, and revise the turning angles of normal wheels except an abnormal wheel in which a fault occurred, according to the analysis result; and a wheel controller configured to control steering of the wheels according to the turning angles of the wheels, input from the processor.

A driver assistance system of a vehicle includes a control operable to control steering of the vehicle and braking of the vehicle responsive to determination of an emergency driving event. The control operates in a normal operation mode and an emergency mode. The control, responsive to determination of an emergency driving event, engages the emergency mode. The control, responsive to determination of a lane in which the vehicle is traveling, and responsive to an emergency mode activation, may control the steering of the vehicle to steer the vehicle along the determined lane. Optionally, the control may not control braking of the vehicle to quickly stop the vehicle responsive to an input from the driver indicative of the driver not wanting to stop the vehicle.

In a travel control apparatus for a vehicle, a travel environment information acquisition unit acquires travel environment information on a travel environment of the vehicle. A travel information detector detects travel information on the vehicle in order to execute automatic driving control based on such information pieces. A lateral force generator generates lateral force to be applied to the vehicle during the automatic driving control. A torsion bar is interposed on a torque transmission path of a steering system. A steering wheel angle detector detects a steering wheel angle. A lateral force detector detects the lateral force acting on the vehicle. An intervening steering operation determination unit determines that a driver has performed an intervening steering operation when a characteristic of the detected steering wheel angle and lateral force differs from a reference characteristic that varies univocally when the steering wheel is in a no load condition.

The invention relates to a method for providing lane-keeping support in automobiles during the operation of a fully automatic driver assistance system designed for driver-independent vehicle guidance by means of a control unit which controls the actuatorics of a steering system during operation of this driver assistance system such that the vehicle is maintained within the driving lane, characterized in that, in the event of failure of the steering system, targeted braking interventions are performed in order to maintain the lateral guidance for the lane-keeping support of the vehicle by means of a braking system of the vehicle.

A method can be used to control a steer-by-wire steering system in an emergency steering mode. The method comprises checking a steering system for the presence of a fault state and upon detection of a fault implementing the emergency steering mode, which involves determining a setpoint position of a steering tie rod using a setpoint wheel steering angle, determining a front wheel to be braked and a brake pressure to attain the setpoint position with a control unit, transmitting the front wheel to be braked and the brake pressure to a brake system, braking the front wheel to be braked, and increasing a torque provided by a wheel drive to compensate for a loss of speed of the motor vehicle caused by the braking of the front wheel to be braked.

A vehicle body control system, a control method of the vehicle body control system, and a non-transitory computer-readable storage medium storing a program for performing the method may alleviate deterioration of steering performance of a vehicle when an electric power steering (EPS) system of the vehicle fails. The vehicle body control system includes a brake device configured to brake the vehicle, a detector configured to detect a failure of the EPS system, a steering sensor configured to detect an operation of a steering wheel of the vehicle to generate steering operation information, a controller configured to receive the steering operation information and generate a target yaw rate when the failure of the EPS system is detected, and control a brake device to generate a differential braking force required for the calculated target yaw rate.

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 embodiment is a redundant control system for autonomous steering including a sensor in a vehicle configured to sense information for autonomous driving, a main steerer configured to actuate a steering motor to perform steering, first autonomous controller configured to use data provided from the sensor to determine a target steering angle through real-time lane recognition and to control the main steerer, an auxiliary steerer configured to use a brake module composed of a main brake and an auxiliary brake to perform steering, and a second autonomous controller configured to control the auxiliary steerer to perform supplementary steering through partial braking and application of additional actuation in the event of abnormal operation of an automatic steering function using the first autonomous controller and to control backup braking through the auxiliary brake when the main brake fails.

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 number of variations are disclosed including a computer program product and method of modifying brake-to-steer brake pressure commands, based on brake temperature, in real time as well as to create temperature dependent powertrain control and temperature dependent brake cooling.
