VEHICULAR CONTROL SYSTEM FOR EMERGENCY HANDLING
20190092323 · 2019-03-28 ·

A vehicular control system includes a control disposed at a vehicle. A camera is disposed at the vehicle and has a field of view exterior and at least forward of the vehicle. The control is operable to at least partially control driving of the vehicle responsive to determination of an emergency driving condition. The control, responsive to determination of an emergency driving condition, determines a target stopping location ahead of the vehicle at a road along which the vehicle is traveling. The control determines the target stopping location responsive at least in part to processing of image data captured by the camera. The control, responsive to determination of the target stopping location, at least partially controls driving of the vehicle to the target stopping location.

METHOD FOR INFLUENCING THE DIRECTION OF TRAVEL OF MOTOR VEHICLES
20190039651 · 2019-02-07 · ·

A method for influencing the direction of travel of motor vehicles. The motor vehicle has a first steering system, having at least one steering axle with at least two wheels. The wheels are connected to the steering axle through wheel suspensions that can be adjusted by actuators. A redundant steering system is realized by adjusting a steering roll radius of at least one of the steering axles, according to which a force component acting orthogonally to the direction of travel in the region of at least one wheel is applied to the first steering system.

METHOD FOR CONTROLLING A VEHICLE WITHIN A CONFINED SITE, CONTROL UNIT AND VEHICLE
20240262419 · 2024-08-08 ·

A method for controlling a vehicle within a confined site, the method including, following a determination that there is no steering system available in a vehicle that can be controlled by steering control signals generated in automated fashion in order to influence a steering angle of wheels of a steered vehicle axle of the vehicle in automated fashion, specifying a path between a starting area and a specified destination area within the confined site, and generating drive control signals and steering braking control signals such that, during subsequent automated control of a drive system and of a brake system using the control signals, the vehicle moves from the starting area along the path to the specified destination area, and the steering angle varies owing solely to automated control of the brakes of the brake system.

Vehicle dynamic control system for emergency handling
10144419 · 2018-12-04 · ·

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.
