Abstract
A vehicle warning system has an obstacle sensor for detecting approach of an obstacle to a vehicle, tactile information-generating elements for notifying a driver of the obstacle information based on information received from the obstacle sensor, and a controller for controlling the actuation of the tactile information-generating elements. The tactile information-generating elements are installed in the cushion of a driver seat, with a fore-and-aft and/or left-right arrangement. The controller controls the tactile information-generating elements based on the information from the obstacle sensor as well as information from one or more of a steering wheel-sensor, a blinker sensor, a brake sensor, and a vehicle speedometer.
