    • The present invention provides a vehicle navigation system that can customize an optimum route to the driver's road preference. The vehicle navigation system includes at least one data table that contains a set of road data. Each set of road data represents characteristics of one road segment, such as a travel time, a length and a type of the road segment. The navigation system also includes at least one coefficient table that contains a number of coefficients. Each coefficient corresponds to one road segment. In a route search operation, an optimum route is calculated so as to optimize road data that have been modified by weighting the road data by the coefficients. The coefficients are changed based on the user's personal preference on the corresponding road segments. More specifically, a coefficient is penalized when the corresponding road segment that was part of the optimum route was not traveled. On the other hand, a coefficient is credited when the corresponding road segment that was not part of the optimum route was actually traveled.
    • 本发明提供一种车辆导航系统,其可以根据驾驶员的道路偏好来定制最佳路线。 车辆导航系统包括至少一个包含一组道路数据的数据表。 每组道路数据表示一条路段的特征,例如行驶时间,路段的长度和类型。 导航系统还包括至少一个包含多个系数的系数表。 每个系数对应于一个路段。 在路线搜索操作中,计算最佳路线,以便通过系数对道路数据进行加权来优化已经修改的道路数据。 系数根据用户对相应路段的个人喜好而改变。 更具体地,当作为最佳路线的一部分的对应的路段未行进时,系数被惩罚。 另一方面,当不是最佳路线的一部分的对应路段实际行驶时,系数被记入。
