摘要： A system and a method for updating and sharing crossroad dynamic map data are disclosed. The method includes steps of receiving a detection information outputted from an on-vehicle detecting device, wherein the detection information includes a host-vehicle absolute coordinate, a host-vehicle course, a host-vehicle speed, a relative speed between an object and the host vehicle, and an initial relative coordinate between the object and the host vehicle; respectively performing matching procedures to the host-vehicle absolute coordinate and the initial relative coordinate by respectively adding estimated coordinate shifts to obtain a matched host-vehicle absolute coordinate and a matched relative coordinate; performing a coordinate rotation transformation to the matched relative coordinate to obtain a matched transformed coordinate; merging the matched host-vehicle absolute coordinate and the matched transformed coordinate into crossroad-section map data to form crossroad dynamic map data; and sharing the crossroad dynamic map data.

摘要： A map-information obstacle-tracking system and a method thereof are provided. The system is installed in a vehicle. The method includes: using a vehicular dynamic positioning module to acquire a position of a vehicle, and using a map-information module to acquire map-information routes of an area neighboring the position of the vehicle; comparing position of the vehicle with the map-information routes to find out candidate routes in the moving direction of the vehicle; determining one of the candidate routes where said obstacle appears, and predicting a moving trajectory of the obstacle; estimating and outputting a position of the obstacle. The present invention is characterized in using map-information and able to acquire the curvature and slope of the front curved lane. Therefore, the present invention can improve the precision of the obstacle position and stabilizes the accuracy of detecting an obstacle in a curved lane.

摘要： A system and a method for active steering control with automatic torque compensation are disclosed with a processor that generates a targeted torque signal after receiving a steering assistance signal generated by an active driver assistance device, overlays the targeted torque signal on a driver's torque signal after receiving the driver's torque signal sensed by a torque sensor to generate a steering torque signal, and performs an assistance logic algorithm according to the steering torque signal. As the assistance logic algorithm is performed based on both the steering assistance signal and the driver's torque signal, the steering assistance effect provided by the system and the method will not resist against the way of driver's steering, allowing the driver to easily and stably control the vehicle.

Firstly, an electronic map having a plurality of paths, a plurality reference images, and characteristic positions of the plurality of paths and the plurality reference images is provided. Next, at least two positioning images of the signs closest to the vehicle are sequentially retrieved. The reference image identical to the positioning images are searched on the electronic map and used as characteristic images. When the order of all the characteristic images corresponds to the order of all the positioning images, the position of the vehicle is estimated according to the path corresponding to all the characteristic images and the characteristic positions of all the characteristic images.
