Abstract:
The present invention relates to a method for assisting a driver by means of at least one collision warning system, the method comprising the steps of: measuring a visual activity of the driver based on the driver's head and/or eye movement; assessing a driver's level of attention to driving tasks based on the measured visual activity; and adapting a warning threshold of the at least one collision warning system to the assessed driver's level of attention.
Abstract:
When an obstacle is sensed on a side of a vehicle, the future position of the vehicle after a prescribed time is predicted. When the predicted vehicle future position reaches a prescribed lateral position in the lane width direction, a decision to start a control is made, and the vehicle is controlled in a direction to prevent it from coming too close to the obstacle. If a state occurs in which the obstacle is sensed after not being sensed (i.e., it is first sensed), a decision to start the control is suppressed.

Abstract:
Present invention discloses a method and a system for assessing a vehicle driver's excessive workload due to the driver's performance of secondary tasks and responsively adapting a subsystem of the vehicle's operation based thereupon, said method comprising: taking a series of measurements of a driver's head or eye movement variability and inputting the measurements to a computer processor for analysis; analysing the input measurements using the computer processor and determining therefrom whether an excessive amount of driver attention is being paid to a secondary task based on an assessment of driver workload; and tailoring performance of a subsystem of the vehicle based upon said assessment of the driver's excessive level of workload and thereby assuring that behaviour of the vehicle appropriately matches the driver's present level of attentiveness to driving control tasks, as well as a computer program and a computer program product for performing such a method.
Abstract:
The present lane departure prevention system can prevent a vehicle from departing from a lane of travel, even when the vehicle tows a towed vehicle. When the towed vehicle is detected (S2), the lane departure prevention system changes a target yaw moment which is used in normal departure avoidance control operation, based on a force input to the vehicle from the towed vehicle, which is caused by carrying out departure avoidance control, thereby controlling the vehicle so as not to depart from the lane by corrected yaw moment.
Abstract:
The invention relates to a system for automatic following-distance control, notably in congested traffic, in a motor vehicle (1) so as to facilitate driving in congested traffic by both taking over transverse steering by means of an automatic steering system and ensuring that a given distance is maintained to a vehicle driving ahead. The latter function calls for an adaptive driving and brake control system with a 'stop' and 'go' function. According to the invention selection and decision means (5, 6, 7, 8, 9) are provided for which are able to selected both control parameters and control types, for example following-distance control of the motor vehicle (1) in accordance with road markings recognized by video camera or in accordance with a detected leading vehicle. The system is divided into hierarchical levels (I-IV). The driver always remains in the monitoring and adaptation circuit assigned to the highest hierarchical level (IV) so that he has the highest priority and can overrule the system at any time.
