Title: Method and apparatus for self-trouble shooting of electronic controller for vehicle
Inventor: ITO YASUNOBU
IPC: B60T8/88
Filed: 1993-12-21
Abstract: PURPOSE:To enable diagnosing of an event with an unsustained state of a trouble to be generated in an individual slave ECU by minimizing a cost increase factor such as the additional parts. CONSTITUTION:A master ECU has a processing function for taking in diagram information of individual slave ECUs obtained by a trouble diagnosis of a system as managed by itself (diagram memory function) and a trouble diagnosis of a system as managed by the individual slave ECUs (self-diagnosis function. The slave ECUs execute a self trouble diagnosis constantly to demand the master ECU for the current date at the detection of a trouble. When time information is sent to a slave ECU, the date of the generation of the trouble and the contents of the trouble is preserved in a memory as diagram information together. Thus, as for the trouble to be detected with any slave ECU, the date of the generation thereof and the contents thereof are preserved sequentially by using the time-piece function of the master ECU thereby enabling the trouble shooting of an electric controller without adding a new time-piece function.

Title: Velocity measuring instrument
Inventor: TAGUCHI HIDEOMI
IPC: G01S13/53
Filed: 1999-12-07
Abstract: PROBLEM TO BE SOLVED: To obtain a velocity measuring instrument capable of switching a measuring-object lane by regulating a measuring range by a distance uniquely without being influenced by the reflecting cross section of a measuring-object vehicle without measuring the traveling speed of the non-objective vehicle of the measurement, which travels through an adjacent lane far from the measuring-object vehicle. SOLUTION: A velocity measuring instrument 24 having a receiving gate timing switching part forms a measuring area B12 and when the measuring- object vehicle A2 passes through the inside of this area B12, the instrument 24 measures its velocity. However, since the area B12 is to be formed by restricting reception after the lapse of a fixed time from the rising of a transmission pulse 18, the area B12 is nearly constant without regard to the reflecting cross section of the measuring-object matter and it is also similar when a measuring-object vehicle B22 enters a measuring area C23. Further, by switching the measuring area optionally or automatically, the traffic flow data of each lane is obtained securely.
