DEVICE AND METHOD FOR STABILIZING A MOTOR VEHICLE
A device for stabilizing a vehicle after a collision against a lateral carriageway boundary, includes a lane recognition system, with which information relating to the course of the lane is determined or detected. A collision detection unit identifies a collision of the vehicle against the lateral lane carriageway boundary on the basis of signals from at least one sensor or on the basis of a driving state variable. The device also includes a steering actuator for steering a steering system and a brake actuator for controlling one or more wheel brakes. A target path determination unit determines a target path for the vehicle on the basis of the course of the lane determined or detected before or at the time of the collision. A controller guides the vehicle onto the target path and/or stabilizes the vehicle via a steering intervention and/or individual wheel brake interventions.
METHOD AND APPARATUS FOR CONTROLLING BRAKE SYSTEM BASED ON PRECEDING VEHICLE RECOGNITION
A method and device for controlling brake system based on preceding vehicle recognition are disclosed. The device comprising: a data collecting unit configured to collect front data and rear data of a preceding vehicle, a driving trajectory extracting unit configured to extract a driving trajectory of a lane in which the vehicle is traveling, a preceding vehicle analysis unit configured to determine driving information of the preceding vehicle, a preceding vehicle determining unit configured to determine intervention of the preceding vehicle or deviation of the preceding vehicle with respect to the driving trajectory, and a control unit configured to control the brake system.
Lane departure prevention system of vehicle
A lane departure prevention system includes a controller configured to control a braking force of vehicle wheels such that a lane departure prevention yaw moment is applied to a vehicle. The controller determines whether there is a likelihood that the vehicle enters a spinning state based on at least one of a difference between an actual yaw rate and a normative yaw rate of the vehicle calculated based on a steering angle, a vehicle speed, and the lane departure prevention yaw moment, and a degree of braking slip of a turning inside wheel when the lane departure prevention yaw moment is a yaw moment for preventing departure of the vehicle from a lane to a turning outside, and applies a spin prevention yaw moment to the vehicle when it is determined that there is a likelihood that the vehicle will enter the spinning state.
Assistance with ending shoulder driving by a motor vehicle
In a method for ending shoulder driving, it is detected by means of a detection unit of a motor vehicle that a wheel is located on a shoulder. By means of a sensor unit, a driver's reaction is recorded, and by means of a computing unit, the driver's reaction is assigned to one of at least two intensity classes. By means of a control unit, an intervention in controlling the vehicle is undertaken counteracting the driver's reaction when the driver's reaction has been assigned to a first intensity class, and an intervention supporting the driver's reaction is undertaken when the driver's reaction has been assigned to a second intensity class.
Lane keeping for autonomous vehicles
A system for a lane keeping feature of a vehicle is provided. The lane keeping feature has a predefined safety requirement criterion for keeping the vehicle within bounds while the lane keeping feature is active. The system comprises a road estimation module and a trajectory planning module. The road estimation module is configured to receive sensor data comprising information about a surrounding environment of the vehicle, and to determine a drivable area based on the sensor data. The drivable area comprises a left boundary and a right boundary extending along a direction of travel of the vehicle, wherein each boundary comprises a plurality of points distributed along each boundary, each point being associated with a confidence level. The trajectory planning module is configured to receive the determined drivable area, and to determine a nominal trajectory for the vehicle based on the received drivable area.
Brake system for detecting defects for a transportation vehicle, transportation vehicle with a brake system for detecting defects, and method for operating a brake system for detecting defects
A brake system for a transportation vehicle, a transportation vehicle having a brake system, and a method for operating a brake system. The brake system has two control units, wherein the respective control unit actuates a respective brake circuit of the brake system, which includes two of four service brakes and one of two electric parking brakes of the brake system. In response to a defect in one of the brake circuits, the control unit of the other brake circuit actuates the respective brakes of the other brake circuit, to carry out trailer combination stabilization of a trailer combination having the transportation vehicle and a trailer coupled to the transportation vehicle; and/or to steer the transportation vehicle in the case of a defect in a steering system of the transportation vehicle based on a steering command of a control device for autonomous driving.
