And the vehicle interface requires a 12V DC power line 1 wiresystem ground 1 wireand a system communications signal 1 wire. The master microcontroller preferably controls the impedance switch to disconnect the power supply from the low impedance line when a communications signal or a portion thereof is transmitted over the power communications line. The sensor is preferably configured for active traffic environment sensing using ultrasound. An impedance switch is disposed in the low impedance line and is controlled by the master microcontroller to control the flow of power through the low impedance line. From Wikipedia, the free encyclopedia. A low impedance line 32 having a low impedance resistor is also connected to the power source

    The ECU requires nine connections for a system with four ultrasonic sensors The master task transmits a header that consists of a break signal followed by synchronization and identifier fields. And the vehicle interface requires a 12V DC power line 1 wiresystem ground 1 wireand a system communications signal 1 wire. The digital values communicated between the master microcontroller and sensor are preferably delineated by selective arrangement of the on and off flow of power over the power communications line.

    The system according to claim 3wherein each external ultrasonic sensor includes a diode and a capacitor operably connected between the at least one power communications wire and a power supply input for the external sensor in order to continuously supply power to the external sensor when no power flows over the at least one power communications wire. Each ultrasonic sensor further includes: a communications port and a sensor power line operably connected to the power source, wherein the sensor power line branches off of the power communications line; a capacitor on the sensor power line; and a diode positioned between the capacitor and the sensor power line.

    As LIN Slave nodes should be as cheap as possible, they may generate their internal clocks by using RC oscillators instead of crystal oscillators quartz or a ceramic.
