MONITOR DEVICE OF ONE SENSOR AT LEAST HAVING TWO CONNECTING ENDS AT LEAST, AND METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To improve the monitoring of an induction type sensor by regulating the current carried within the sensor by switching means capable of imparting a voltage to the connecting end of the sensor and switchable means. SOLUTION: A vehicle rotating speed sensor 103vr is connected to a monitor device 104 through two lines 105a and 105b. A sensor 103hr is also connected to the device 104 through both lines 106a and 106b. Both the potentials present on the connecting end of a sensor 103vl are supplied to the device 104 through two lines 107a and 107b. The same is applied to a sensor 103hl. The device 104 is connected to a brake pressure control device 109 through two lines 110a and 110b, and a signal transmission is performed from the device 104 to the device 109 through the line 110a. The device 109 is connected to a hydraulic control device 111 through lines 112a and 112b, and a signal transmission is performed from the device 109 to the device 111 through the line 112a.
