Abstract
Official abstract text for this publication.
A method and system for jerk-free stopping of a motor vehicle to automatically bring the motor vehicle to a standstill at a predetermined destination point, wherein the deceleration exerted on the motor vehicle is ascertained, entirely or in part, as the difference of a spring force component and a damping component, with the damping component being proportional to the present vehicle velocity.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for jerk-free stopping of a motor vehicle to automatically bring the motor vehicle to a standstill at a predetermined destination point comprising: a power source; a friction brake system, said power source and said friction brake system exerting a deceleration force to decelerate the vehicle, said deceleration force based on a difference between a spring force component and a damping component, wherein said damping component is proportional to vehicle velocity. 2. The system of claim 1 wherein said spring force component remains constant up to a predetermined distance to the destination point; and, decreases in a linear, tan hyperbolic or exponential manner from said predetermined distance to the destination point for the remaining distance to the destination point. 3. The system of claim 1 wherein said deceleration decreases linearly, with a first slope value, up to a predetermined distance to the destination point; and decreases in a linear manner, with a second slope value, from said predetermined distance to the destination point for the remaining distance to the destination point, wherein said second slope value has a greater absolute value than said first slope value.
