专利汇可以提供Automatic motorway driving system for motor vehicles专利检索,专利查询,专利分析的服务。并且This invention relates to an automatic motorway driving system in which passive rectangular coils are buried in a motorway, preferably in both the normal driving and overtaking lanes, for cooperation with a front transmitter loop and two rear receiver loops carried by each vehicle. Each vehicle has an alternating current generator which applies an alternating current to the transmitter loop and which scans a range of frequencies cyclically so that signals picked up through inductive linkage of the receiver loops with the buried coils can provide servo control signals indicative of the distance of preceding vehicles or the presence of overtaking vehicles. The two receiver loops symmetrically placed at opposite sides of the vehicle and electronic comparison of the signals picked-up thereby is used to control a vehicle steering servomechanism to maintain the vehicle centrally in the normal driving lane.,下面是Automatic motorway driving system for motor vehicles专利的具体信息内容。
