BRAKING DATA MAPPING
A system for monitoring vehicle behavior based on vehicle control data includes a network access device configured to receive braking data from multiple vehicles, the braking data corresponding to vehicle braking events having a brake pressure that is equal to or greater than a threshold brake pressure and including a corresponding location. The system further includes a processor coupled to the memory and configured to determine an event of interest on a roadway by analyzing the braking data and the corresponding location, and to transmit a notification of the event of interest to at least one vehicle.
VEHICLE DISTURBANCE HANDLING SYSTEM

Method for operating a transversal guidance system of a motor vehicle, and motor vehicle
The invention elates to a method for operating a transversal guidance system of a motor vehicle through two independent channels to perform automatic transversal guidance interventions. Through the first channel, transversal interventions are performed via a first transversal guidance actuator controlled by means of a driver-operated steering handle. Through the second channel, a vehicle system sets a target, roll angle, and a second transversal guidance actuator is controlled by a transversal guidance system that performs a transversal guidance intervention based on the roll angle. The vehicle system displays the roll angle as a notification to the driver of the transversal guidance intervention. The invention also relates to a motor vehicle configured to perform the method.

Delay Autonomous Braking Activation Due to Potential Forward Turning Vehicle
A method and controller are provided for delaying activation of autonomous emergency braking of a host vehicle, based on a determination that autonomous emergency braking is not needed because a forward vehicle in front of the host vehicle is turning out of the path of the host vehicle. The controller receives inputs from sensors arranged on the host vehicle and includes a processor for determining whether and when to activate autonomous emergency braking. The processor includes control logic that determines whether a forward vehicle is present in front of the host vehicle and whether the forward vehicle is expected to turn out of a path of the host vehicle prior to the host vehicle reaching a current position of the forward vehicle. Based on the inputs from the sensors, the control logic determines whether to delay activation of the autonomous emergency braking of the host vehicle for a time value.

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.
