The vehicle-assisted navigation system is applied to the vehicle navigation map, and the vehicle navigation system 1 is an electronic map database 11 respectively. Positioning module 12: route planning unit 13, and navigation unit 14. 2 The electronic map database 11 stores a plurality of map information 15 , and the map information 15 further includes a plurality of road information 151 and a plurality of parent numbers, and a message 'such as a traffic light switching time m. The satellite positioning module 12 is used to provide a location message 121 for the vehicle. The road, planning list Tt 13 is based on the starting position 131, the target position 132 and the map. The vehicle travel route 133 includes a road that passes between the start position * 131 and the target position 132. The navigation unit 14 provides a navigation message 141 that reduces driving costs based on the location information 121, the travel route 133, and the traffic information. For example, the navigation sheet 7G 14 can switch the time 152 according to the signal of the traffic light, and provide a traffic light crossing prompt message 141 to the driver, such as an acceleration or deceleration message. Because the vehicle stops moving when it is started, it still consumes oil, which increases the driving cost for the driver. Therefore, when the navigation unit 14 determines that the vehicle is obviously unable to pass the traffic light according to the speed of the vehicle and the light signal switching time 152 of the traffic light, a deceleration message is generated to remind the person to decelerate to reduce the fuel consumption; when the navigation unit 14 determines When the vehicle needs to be accelerated to pass the traffic light, an acceleration message is generated to remind the driver to accelerate to avoid additional fuel consumption due to the red light. In addition, the navigation unit 14 can determine whether the vehicle is stationary for more than a predetermined time according to the location message 121, for example, currently driving the vehicle and driving the vehicle, if so, the navigation unit 14 generates a suggested flameout message; M2 to remind the driver Turn off the flame to reduce unnecessary fuel consumption. If the electronic store 11 can also contain parking information, the navigation unit 14 can provide navigation information to the parking lot with lower cost when the driver arrives at the destination. Please refer to FIG. 2, which is a schematic diagram of the vehicle navigation system of the present invention. The vehicle navigation system is suitable for a vehicle navigation, and the vehicle 'aviation system 2 is an electronic map database 2 j, respectively. Group 22, route planning unit 23, and navigation unit 24. The Eight Diagrams E-Map Database 21 stores a number of limits, cymbals, and/or t-hearts. The grade of a road, the number of speed traffic numbers, the number of times, the time, and the configuration of the vehicle. The bit module is used to raise the energy consumption line planning unit 23 according to the traffic weight consumption _ table 26 and the road information, calculate the right of the roads and the vertical axis is the middle level (four) for the driving speed, the road The higher the level, J: the number of kilometers that can be 1^ σ仃. In general, the road/height is higher, and the road with a larger width, 1313348, the higher the speed, and the energy consumption of the vehicle speed higher than 50 km/h is lower than the low speed. Energy consumption of 50 kilometers per hour. Therefore, roads that can travel at higher speeds have higher weights, while roads that can only travel at lower speeds have lower weights. Similarly, roads with lower toll rates have higher weights, while roads with higher toll rates have lower weights. Roads that are less prone to congestion at present have higher weights, while roads that are more susceptible to congestion have higher Low weight. Then, the route planning unit 23 further plans a driving route 233 for reducing the driving cost according to the starting position 231, the target position 232, the road weights and the map information 25, and reducing the driving cost means lower fuel consumption or Lower tolls. The navigation unit 24 provides a navigation message 241 based on the location message 221 and the vehicle travel route 233 to guide the driver to the target location 232. In addition, the electronic map database 21 may include a traffic signal, such as a traffic light switching time, and the navigation unit 24 may provide driving cost reduction according to the location information 221, the driving route 233, and the traffic signal information as needed. The navigation message 241 further reduces the driving cost of the driver traveling to the target location 232. Referring to Figure 4, there is shown a flow chart of the steps of an embodiment of the vehicle navigation method of the present invention. This embodiment allows the driver to travel from the starting position to the target position at a lower driving cost. In the figure, the vehicle navigation method includes the following steps: Step 40: providing a plurality of map information, wherein each map information includes road information of a plurality of roads and a plurality of traffic number messages, such as a traffic light switching time of the traffic light; 41: providing a location information of the vehicle, the location information may be generated by a global positioning module of 9 1313348; Step 42: planning a driving route according to the starting location, the target location, and the map information; Step 43: According to the location Messages, driving routes and traffic semaphore messages generate a navigation message that reduces driving costs, such as prompting acceleration/deceleration messages, which reduces the driver's waiting time for traffic lights and reduces additional fuel consumption, or alerts the flameout message to reduce No additional fuel consumption due to traffic jams or others. Referring to Figure 5, there is shown a flow chart of a further embodiment of the vehicle navigation method of the present invention, which allows the driver to travel from the starting position to the target position at a lower driving cost. In the figure, the vehicle navigation method comprises the following steps: Step 50: providing a plurality of map information and a row of vehicle and energy consumption relationship table, wherein each map information includes road information of a plurality of roads, such as road grade and speed limit. , width, number of lanes, slope, time of frequent congestion, number of traffic signs or toll rates configured, etc.; Step 51: Provide a location message of the vehicle, which can be generated by a global positioning module; Step 52: Calculate the weights of the roads according to the driving and energy consumption relationship table and the road information. For example, the roads that can drive higher speeds have higher weights, while the roads that can only drive lower speeds have lower roads. The weight. Similarly, roads with lower toll rates have higher weights, while roads with higher toll rates have lower weights. Roads that are less prone to congestion at present have higher weights, while roads that are more susceptible to congestion have higher Low weight; Step 53: Plan a driving route that reduces driving costs based on a starting location, a target location, such road weights, and such map information; 1313348 Step 54: Based on location information and driving to reduce driving costs Route, providing a navigation message.
