Abstract
A vehicle obstacle detecting system having a combination of different kinds of detectors, such as a laser radar and a millimeter-waver radar, to detect an obstacle present ahead of the course of vehicle travel. The system determines whether the detection output of the laser radar is similar to that of the millimeter-wave radar. When the result is positive, obstacle avoidance control is conducted based on the output of either the laser radar or the millimeter-wave radar. When the result is negative, it is determined that the laser radar (the detector normally of superior performance) is degraded and, based on the output of the millimeter-radar, obstacle avoidance control is conducted. With this, the outputs of the different kinds of detectors are fused and unified optimally, enabling effective obstacle avoidance control.
