Title:
MEASUREMENT CONTROLLER FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2002/015152
Kind Code:
A1
Abstract:
The control precision of when a vehicle is controlled on the basis of the results of sensing by means of a camera (1) and a radar (4) is improved. A vehicle measurement controller mounted in a vehicle comprises image processing means (2) for imaging the surroundings of the vehicle and processing an image signal, radar signal processing means (5) for transmitting a radio wave or light to objects surrounding the vehicle and processing a received signal, and control means (8) for controlling a brake, a throttle, or a transmission on the basis of the results of the outputs from the image processing means (2) and from the radar signal processing means (5). The information outputted from the image processing means (2) and the information from the radar signal processing means (5) each includes time information about the imaging time when the imaging is carried out and measurement time when the measurement is carried out so as to adjust the order of the imaging time and the measurement time. In such a way, even if the processing time of when the imaging and measurement object is simple is different from that of when the object is complex, the imaging time and the measurement time are determined. Therefore, a processing appropriate for the imaging and measurement times is carried out, thereby controlling precisely the travel of the vehicle.
