Emergency in-lane steering assist with braking
An emergency in-lane steering assist system for use during a braking event comprises an object sensor for detecting the presence of an object in front of a motor vehicle and providing data from which the distance from the object to the motor vehicle is determined and a velocity sensor providing data from which the forward velocity of the motor vehicle is determined. A controller in communication with the object sensor and the velocity sensor calculates a Time to Contact (TTC) with the detected object and a steering system is responsive at least in part to operation by the controller. If the calculated TTC is less than a predetermined TTC, the controller provides a lateral steering input during the braking event to reduce the linear distance traveled by the motor vehicle relative to a predetermined path in the lane.
LANE KEEPING ASSIST AND A METHOD FOR ASSISTING A LANE KEEPING
An object-based lane-keeping-assist for a vehicle, including a first sensor, a second sensor, and a lane keeping function. The first sensor determines a relative position of the vehicle with respect to a lane. The second sensor detects a position of an object in an adjacent lane. The lane keeping function keeps the vehicle around a default line in the lane. The lane-keeping-assist includes a control unit having a processor and a memory with stored instructions that, when executed on the processor, cause the following: triggering a steering intervention when a distance between a vehicle side and a trigger line is below a predetermined threshold indicating an unintended lane departure of the vehicle; completing the steering intervention, when the default travel line of the lane keeping function has been reached; and shifting the trigger line when the second sensor has detected the object in the adjacent lane.
Control apparatus for vehicle
A control apparatus for controlling a vehicle which is provided with a braking/driving force varying device capable of individually changing a braking/driving force acting on each of wheels (FL, FR, RL, RR) with respect to each wheel. The control apparatus includes a target state quantity setting device for setting a target state quantity corresponding to a target motion state of the vehicle; and a target braking/driving force setting device for setting a target braking/driving force, which is a target value of the braking/driving force, such that a state quantity corresponding to the target state quantity and a steering reaction force transmitted to a steering apparatus from the wheel are the set target state quantity and a predetermined target steering reaction force, respectively, on the basis of a relative relation, which is set in advance, between the state quantity and the steering reaction force, and a left-right braking/driving force difference of front wheels and a left-right braking/driving force difference of rear wheels.
