    • An on-vehicle device for road-vehicle communication includes a communication unit for exchanging information with an on-road device, and storage unit for storing necessary information. When a communication error occurs between the on-vehicle device and the on-road device, information regarding the communication error is stored in the storage unit. The vehicle device further includes a card read-write unit into which a control card is removably inserted. The control card has a storage area for storing the above-described error information and information necessary in the on-vehicle device. Via the card read-write unit, information stored in the storage unit is transferred to the storage area of the control card to be stored therein, and information stored in the storage area of the control card is transferred to the storage unit to be stored therein. Accordingly, when a communication error occurs between the on-vehicle device and the on-road device, information regarding the communication error is transferred from the storage unit to the control card, so that information regarding the communication error can be obtained from the on-road device via the control card.
    • 用于道路车辆通信的车载设备包括用于与路上设备交换信息的通信单元和用于存储必要信息的存储单元。 当在车载设备和路上设备之间发生通信错误时,关于通信错误的信息被存储在存储单元中。 车辆装置还包括卡读取单元,控制卡可拆卸地插入其中。 控制卡具有用于存储上述车载装置所需的上述错误信息和信息的存储区域。 通过卡读写单元,存储在存储单元中的信息被传送到要存储在其中的控制卡的存储区域,并且存储在控制卡的存储区域中的信息被传送到存储单元以被存储在其中 。 因此,当在车载设备和道路上设备之间发生通信错误时,关于通信错误的信息从存储单元传送到控制卡,从而可以从在线设备获得关于通信错误的信息, 道路装置通过控制卡。

    • A vehicle-carried unit for automatic toll-paying systems carried on a vehicle for automatically paying a toll from a plurality of IC cards through communication with an on-road unit installed on a road. The toll is calculated at an exit gate in accordance with predetermined toll information (step 432), and it is judged whether or not payment is possible in accordance with balance information of a plurality of IC cards stored in a storage circuit (step 434). In the case of being capable of payment, the toll is subtracted (step 486), and a payment signal is transmitted to the on-road unit (step 488). Because balances of a plurality of IC cards are stored as described above, it becomes unnecessary to stop at a tollbooth due to shortage in balance.
    • 一种用于自动收费系统的车载单元,用于通过与安装在道路上的道路单元进行通信而从多个IC卡自动支付费用的车辆上。 根据预定的费用信息在出口处计算费用(步骤432),并且根据存储在存储电路中的多个IC卡的余额信息来判断是否可以进行支付(步骤434)。 在能够支付的情况下,减去费用(步骤486),并将支付信号发送到道路单元(步骤488)。 由于如上所述存储多个IC卡的余额,所以由于平衡不足而不必在收费站停止。

    • A road/vehicle communication method for communication between a plurality of road devices, which are provided with a plurality of road antenna devices at respective gates, and a vehicle communication device, which is mounted to a vehicle and transmits and receives information to and from the plurality of road devices by radio waves, includes the steps of: when the vehicle passes through a first gate, the vehicle communication device receiving gate information which relates to the first gate and which is transmitted from a road antenna device of the first gate, and the vehicle communication device transmitting the received gate information at a second gate; the second gate receiving gate information from a plurality of vehicle communication devices, and computing a communication probability for each antenna device of the first gate when a number of received gate information corresponding to the first gate has reached a predetermined number; and comparing, for each road antenna device, the communication probability with a predetermined reference value, and detecting, as a malfunctioning road antenna device, a road antenna device for which a difference between the communication probability and the predetermined reference value exceeds a predetermined value. Accordingly, at the second gate, a malfunctioning road antenna device can be detected among the road antenna devices of the first gate, and measures can be taken with respect to the malfunctioning road antenna device.
    • 一种道路/车辆通信方法,用于在各个门上设置有多个道路天线装置的多个道路装置与车辆通信装置之间进行通信,该车辆通信装置安装在车辆上并向其发送和接收信息 通过无线电波的多个道路装置包括以下步骤:当车辆通过第一门时,车辆通信装置接收与第一门相关的门信息,并从第一门的公路天线装置发送, 所述车辆通信装置在第二门处发送所接收的门信息; 第二门从多个车辆通信装置接收门信息,并且当与第一门对应的接收到的门信息的数量已经达到预定数时,计算第一门的每个天线装置的通信概率; 并且对于每个公路天线装置,将具有预定参考值的通信概率进行比较,并且将通信概率和预定参考值之间的差超过预定值的道路天线装置作为故障道路天线装置进行检测。 因此,在第二门处,可以在第一门的道路天线装置中检测到故障的道路天线装置,并且可以针对故障的道路天线装置采取措施。
