Title: Radar device for vehicle
Inventor: YAMAMURA TOSHIHIRO
IPC: G01S13/93
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To secure high responsiveness to a sudden change of relative speed while keeping the resolution high by eliminating the periodic vibration of relative speed by use of LPF having a cut-off frequency changing with the own car speed. SOLUTION: A distance calculating means 7 detects an inter-vehicle distance. A relative speed calculating means 9 calculates the relative speed from the temporal change of the inter-vehicle distance. A car speed sensor 15 detects an own car speed. According to the own car speed, the cut-off frequency of a LPF 11 is decided to conduct LPF processing. Thus, the following effects are obtained. If the speed of a preceding car is very small, the cut-off frequency of the LPF 11 is made smaller than the frequency of the relative speed vibration in order to eliminate the vibration component of the relative speed due to the change of distance from the preceding vehicle as an error.  On the other hand, if the speed of the preceding vehicle is substantially equal to the own car speed, the cut-off frequency is determined in proportion to the own car speed, so that the higher the running speed is, the smaller the phase lag of the LPF 11 is, and it is possible to improve the responsiveness to the sudden deceleration of the preceding vehicle.

Title: Valve timing control device for internal combustion engine
Inventor: OKAWA NOBUNAO
IPC: F02D13/02
Filed: 1995-02-24
Abstract: PURPOSE: To prevent generation of a trouble due to delay of control, by quickly recognizing a throttle valve fully closed, in an internal combustion engine provided with a variable valve timing mechanism. CONSTITUTION: An electronic control device(ECU) 70, in order to control valve timing, controls an oil control valve 80. That is, in the case of fully closing a throttle valve, a target advance timing is set to zero, and toward this value, a VVT50 is feedback controlled. In the ECU 70, based on not a full closing switch but a detecting result of a throttle sensor 45, in the case that a throttle opening is equal to a value of adding a prescribed opening to a reference opening, the throttle valve is recognized to be fully closed. Consequently, when the throttle valve is actually fully closed, it is recognized to be already fully closed, and in this point of time, the target advance timing is set to zero. The VVT50 is quickly controlled by the ECU 70, to control the actual valve timing so as to be placed in a most delay timing condition.
