Driver assisting system, method for assisting driver, and vehicle incorporating same
First Claim
1. A driver assisting system for assisting a driver, within a driver'"'"'s seat of a vehicle, operating a driver controlled input device of the vehicle, comprising:
- a running environment detecting device configured to detect an obstacle appearing in a running environment around the vehicle and obtain information of a legal speed restriction for a road on which the vehicle is traveling;
a vehicle speed sensor configured to detect a vehicle speed of the vehicle;
a risk calculating section configured to calculate a first type of risk perceived by the driver associated with a possible collision with the detected obstacle and a second type of risk unrelated to the detected obstacle and derived based on the detected vehicle speed and the legal speed restriction;
a tactile stimulus controlling section configured to translate the calculated first type of risk and second type of risk into different first and second forms of tactile stimulus, respectively; and
a tactile stimulus forwarding device configured to forward the calculated first and second type of risk to the driver by applying the first and second forms of tactile stimulus to the driver, via a single device, wherein the single device is the driver'"'"'s seat or the driver controlled input device.

Abstract
A driving assist method and system for assisting a driver operating a vehicle. An obstacle is detected and information of a legal speed restriction on vehicle speeds for a road which the vehicle is traveling on, is obtained. A first type risk perceived by the driver from the detected obstacle is calculated, and a second type of risk is determined by comparing the detected vehicle speed and the legal speed restriction. The calculated first and second type of risk are translated into different first and second forms of tactile stimulus, respectively, and are applied to the driver via a single device to forward the calculated first and second type of risk to the driver. The single device is the driver'"'"'s seat or the driver controlled device.
