Abstract:
1. A driver assisting system for assisting a driver, within a driver's seat, operating a driver controlled input device of a vehicle, comprising: a running environment detecting section configured to detect an obstacle appearing in a running environment around the vehicle and obtain information of a vehicle speed standard for a road on which the vehicle is traveling; a vehicle speed sensor configured to detect a vehicle speed of the vehicle; the vehicle speed standard being a vehicle speed value calculated based on a recommended vehicle speed, which the vehicle is recommended to travel at, taking into account the speed limit for the road, an error of the vehicle speed sensor and fuel economy, a risk calculating section configured to calculate a first type of risk perceived by the driver and associated with a possible collision with the detected obstacle and a second type of risk unrelated to the detected obstacle and derived from determining an amount by which the detected vehicle speed exceeds the vehicle speed standard; 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.
