A surrounding conditions display apparatus captures an image of an area surrounding a movable body and displays the captured image. The apparatus includes a CCD camera for capturing an image of the surrounding are, ultrasonic sensors for detecting a distance to an obstacle present in the surrounding area, and a liquid crystal display for displaying the image captured by the image capturing unit. A color image representing an area including the obstacle is superposed on the displayed image in such a manner that the brightness of the color image decreases with increasing distance from the origin of the area.

A method and system of collecting data concerning thermal properties of roads and using the collected data to form a geographic database that can be used in a vehicle safety system to implement a safety process when the vehicle approaches a location of a potential ice hazard. Data indicative of the thermal properties of roads are collected by driving along roads in a vehicle equipped with equipment that senses thermal properties of the roads upon which the vehicle is being driven. Using the collected data, a geographic database is formed that relates positions along roads to thermal properties of the roads at the positions. A vehicle safety system uses the geographic database, a positioning system that determines a position of the end user's vehicle along the roads represented by the geographic database, and an ice hazard application to implement a safety procedure when the vehicle approaches a location at which a potential ice hazard

A pedestrian detection device, a related method, an air bag system and a vehicle are disclosed. The pedestrian detection device 20 includes an infrared ray sensor 30A, which detects a temperature of a detection object approaching to or in contact with the vehicle 10 to provide a temperature signal, an impact sensor 27a to 27c, which generate impact signals when the vehicle encounters a collision, and an impact collision generation unit 21 operative to generate a pedestrian collision signal upon discrimination that the detection object is a pedestrian, discrimination that the impact signal is being outputted, and discrimination that a direction in which the pedestrian is present and a direction in which the impact is applied to the vehicle falls in a substantially same direction.

An apparatus and method for detecting the road condition for use in a motor vehicle. The system and method detect road data through a temperature sensor, an ultrasonic sensor, and a camera. The road data is filtered for easier processing. A comparison of the filtered road data to reference data is made, and a confidence level of that comparison is generated. Based on the comparison of filtered road data to reference data, the road condition is determined. The driver may be informed and/or stability control systems may be adjusted based on the detected road surface condition.

A lane tracking control system for a vehicle includes a controller which is coupled to a road image detector for taking a view ahead of the vehicle, a vehicle behavior detector for detecting a behavior of the vehicle and a steering control mechanism for executing a steering control in response to a steering control signal. The controller is arrange to calculate a road shape on the basis of the view taken by the road image detector, to determine on the basis of the road shape and the vehicle behavior detected by the vehicle behavior detector whether the vehicle tends to depart from a lane traveled by the vehicle, and to output the steering control signal to the steering control mechanism so as to control the vehicle behavior at a desired behavior when the vehicle tends to depart from the lane.
