Abstract

PURPOSE:To avoid instability in operation result by comparing the relative moving speed measured by the radar type speed sensor and the own speed measured by an own vehicle speed sensor, and controlling an arithmetic device by the result of the comparison. CONSTITUTION:The relative moving speed of a vehicle B and a moving body A is measured by the radar type speed sensor 1. The own speed of the vehicle is measured by the own speed sensor 2. Both speeds are operated and processed in the arithmetic device 3, and the absolute moving speed and the own vehicle speed are compared in a comparator 5. When the relative moving speed is close to zero and within a preset range, the absolute moving speed of the moving body A and the own vehicle speed are regarded as equal, while the operating device 3 is controlled, and the absolute moving speed is measured by the own vehicle speed.
