Capacitive sensor for a vehicle

A capacitive sensor(1) for a vehicle includes an evaluation unit(2) as well as a first transmission electrode and a second transmission electrode for transmitting a respectively associated first measurement signal(S1) and second measurement signal(S2). The two transmission electrodes(3,4) are connec...

description	A capacitive sensor(1) for a vehicle includes an evaluation unit(2) as well as a first transmission electrode and a second transmission electrode for transmitting a respectively associated first measurement signal(S1) and second measurement signal(S2). The two transmission electrodes(3,4) are connected to a respective first and second transmitter output(7,11) of the evaluation unit(2) through an assigned first and second transmission line(5,9) respectively. The evaluation unit(2) alternately outputs the first measurement signal(S1) via the first transmitter output and the second measurement signal(S2) via the second transmitter output. The evaluation unit also connects the respective non-transmitting second or first transmitter output(11,7) to reference potential. Alternatively, a common transmission electrode may output the measurement signal which is then picked up by first and second receiver electrodes(11,7).
