    • An information transmission method and an information transmitter which relieves the feeling of being waiting as much as possible even if the data quantity included in a reply is large. When a search request is given to an information providing center from a vehicle, the center receives the request (S201) and refers to a database in order to respond to the request and obtains a search result (S202). If a plurality of data types such as characters, pictures, etc., are included in the search result, data groups are formed for the types of data, and data quantities of each data group are calculated (S205 and 206). The data groups are arranged in order of data quantity, to determine the transmission order of the data groups (S207). Further, in each data group, the data are arranged in order of quantity of data, to determine the transmission order of the data (S209) and the data are transmitted to the vehicle in this order (S210).
    • 即使包含在答复中的数据量较大,信息发送方法和信息发送器也尽可能地减轻了等待的感觉。 当从车辆向信息提供中心提供搜索请求时,中心接收请求(S201),并且参考数据库以响应该请求并获得搜索结果(S202)。 如果在搜索结果中包括诸如字符,图片等的多种数据类型,则为数据类型形成数据组,并且计算每个数据组的数据量(S205和206)。 数据组按照数据量的顺序排列,以确定数据组的传输顺序(S207)。 此外,在每个数据组中,数据按照数据量的顺序排列,以确定数据的传输顺序(S209),并且以该顺序将数据发送到车辆(S210)。
