AVOIDANCE MANEUVER ASSISTANT FOR MOTOR VEHICLES

摘要

An avoidance maneuver assistant for a motor vehicle includes: a sensory system for monitoring the traffic environment of the vehicle; and an electronic control device, in which an emergency avoidance function is implemented. The emergency avoidance function checks, using sensory data, if an emergency avoidance maneuver is necessary, and then intervenes in the dynamics of the vehicle via an actuator system, using an intervention force varying within predefined limits, to assist in the emergency avoidance maneuver. The control device implements a limiting function, which varies the limits for the intervention force as a function of a difference between actual dynamics determined by actions of the driver and setpoint dynamics determined by the emergency avoidance function.

1. An avoidance maneuver assistant unit for a motor vehicle, comprising:
a sensory system for monitoring a traffic environment of the vehicle; and an electronic control device implementing an emergency avoidance function which (i) checks, using data supplied by the sensory system, whether an emergency avoidance maneuver by the motor vehicle is necessary, and (ii) if the emergency avoidance maneuver is necessary, intervenes in dynamics of the vehicle via an actuator system using an intervention force varying within predefined limits, in order to assist a driver of the motor vehicle in performing the emergency avoidance maneuver, wherein the control device implements a limiting function which varies the limits for the intervention force as a function of a difference between actual dynamics determined by actions of the driver and setpoint dynamics determined by the emergency avoidance function.
