Patent number: 5526242Abstract: A vehicle cornering headlamp system which can be applied to any type of vehicle without changing the correspondence to a radiation angle, and which enables the radiation angle to follow the return of driver's eyes when the vehicle exits a curved road. The angular velocity .omega..sub.new is calculated at the time of travelling on a curved road on the basis of the output from an angular velocity sensor and the vehicle speed v is measured on the basis of distance pulses from a distance sensor. The current angular velocity, .omega..sub.new, is divided by the vehicle speed v to calculate the reciprocal number of a revolution radius r, which is multiplied by a constant K, so as to obtain a target value .theta.s of the radiation angle. Then, on the basis of the difference between .omega..sub.old, the angular velocity detected at a previous time, and .omega..sub.new, it is determined that the vehicle is approaching an end of the curved road when the gradient of the angular velocity .omega.Type: GrantFiled: December 27, 1994Date of Patent: June 11, 1996Assignee: Koito Manufacturing Co., Ltd.Inventors: Kazuki Takahashi, Takayuki Unno
