Title:
車輪回転数センサ
Document Type and Number:
Japanese Patent JP6646655
Kind Code:
B2
Abstract:
A wheel speed sensor for a motor vehicle can be supplied with an operating voltage by a control device. The control device has a load resistance with a load resistance value. An operating voltage can be at a voltage input by the control device. An electrical circuit is designed to determine a turn-on or a turn-off voltage value according to the load resistance value. An operation control is designed to transfer the wheel speed sensor into a normal operation using the operating voltage, when the turn-on voltage value is exceeded, and to transfer the wheel speed sensor into an emergency operation using the operating voltage, when a turn-off voltage value is not met. In emergency operation only a low constant signal level is emitted.
