The semiconductor manufacturer NXP has introduced a transceiver, which one "intelligent control" allows many vehicle functions and thus make a contribution to saving fuel. "Whether radio, seat adjustment or windows, all these functions are networked in driving operation and usually permanently active", said kurt sievers, member of the NXP guide, in the presentation of the chip on thursday.
The CAN transceiver TJA1145 allows individual functions such as those of windows, seat adjustment or sunroof to address individually. That was different: if only a control unit woke up in the CAN network, it also had all the others, even if they had nothing to do. Especially in vehicles with many transceivers – especially in high vehicle classes – the current and thus also the fuel consumption increases. According to NXP, with the new transceivers, a consumption reduction by up to three percent is possible.
According to NXP, the TJA1145 is the first product corresponding to ISO 11898-6 (high-speed medium access unit with selective wake-up functionality), which defines a subnet operation of control devices in the CAN bus system. According to NXP, the chip should be used in some german vehicles of the next generation.
NXP semiconductors based in hamburg had been divided into 2006 from the semiconductor company by philips. The company manufactures chips, among other things, for cars, televisions and identification documents.
