To provide a road shoulder-detecting system which can accurately measure the orientation of a vehicle relative to a road shoulder and the distance to the road shoulder. The present invention includes road shoulder-detecting units 2a, 2b to scan a road surface A in front of a vehicle 1 in the traveling direction of the vehicle 1 and detect a road shoulder B located on the road surface A and a road shoulder-measuring device 21a to measure the orientation of the vehicle 1 relative to the road shoulder B detected by the road shoulder-detecting units 2a, 2b and the distance to the road shoulder B; and the two road shoulder-detecting units 2a, 2b are installed on the traveling direction side of the vehicle 1. The two road shoulder-detecting units 2a, 2b are installed in a higher position than the upper ends of front wheels d.

A collision warning system for a host vehicle includes a false warning reduction arrangement. A collision sensor senses a presence of a target object within a forward path of a vehicle and a navigation system senses the global position of the vehicle. The collision warning system receives the location information and the target object to provide a collision warning to a vehicle operator. To avoid false alerts, the collision warning system compares target object and location to target objects and locations stored in a false alert database. When the target object is provided in the database, a warning is delayed or suppressed. The collision warning system also senses driver reactions to a warning. When a warning results in no reaction by a vehicle operator, the warning is considered a false alert, and the target object and location are stored in the false alert database.

摘要:
Provided is an inexpensive mirror unit having reduced maintenance costs, excellent versatility, and good precision, a distance measurement device and a laser radar, and a mobile body and a fixed object having the mirror unit and the distance measurement device or the laser radar. The mirror unit includes a plurality of pairs of first reflecting surfaces and second reflecting surfaces, being inclined relative to a rotation axis, and extending in directions crossing each other, and the mirror unit rotates about the rotation axis. In the mirror unit, a beam emitted from a light source is reflected on a first reflecting surface of the mirror unit, and then reflected on a second reflecting surface paired with the first reflecting surface, and the beam is emitted while being scanned over an object according to the rotation of the mirror unit. In the mirror unit, the mirror unit includes at least a first reflecting member on which the first reflecting surfaces are formed, and a second reflecting member on which the second reflecting surfaces are formed, and the first reflecting member and the second reflecting member are combined to select an emission angle of a beam emitted from the mirror unit.

The invention relates to a method for processing echo pulses of an active 3D sensor to provide distance measurements of the surroundings in front of the sensor. The method comprises the following steps: - defining a near range distance from the 3D sensor, - defining a last echo distance from the 3D sensor greater than the predefined near range distance, - receiving echo pulses of the signal emitted by the active 3D sensor and subjecting that sequence of echo pulses to a pre-defined trigger condition so that only those echo pulses are taken into consideration which fulfill the predefined trigger condition, and determining the respective trigger times and corresponding distances, - suppressing echo pulses from distances smaller than the predefined near range distance, - out of the echo pulses that fulfill the predefined trigger condition and that are received from distances greater than the predefined near range distance, determining two particular echo pulses, designated first and adaptive echo pulse, according to the following procedure: - determining the first echo pulse as the echo pulse that was received first, - determining the adaptive echo pulse as follows: - if one or more echo pulses received from distances greater than the predefined last echo distance occur, the one of these pulses which was received first will be selected as the adaptive echo pulse, - if there are no echo pulses received from distances greater than the predefined last echo distance, then the last echo pulse received will be selected as the adaptive echo pulse,
- using the two so determined echo signals for providing distance measurements of the surroundings in front of the 3D sensor.
