In the above embodiment, there is another scheme, it is not necessary to set up the road information transmitting unit 20, but the information receiving device 63 of the on-board unit 60 downloads or receives the real-time signal from the instruction transmitting unit 40 in a wireless reading manner, and then the vehicle driving direction data formed by the GPS or the GPS and the electronic compass is compared with the real-time signal to complete the task of judging the state of the signal lamp at the front intersection, so the design has the advantage that only the instruction transmitting unit 40 needs to be connected to the network, and then the relevant signal is downloaded in the on-board unit 60, there is no need to build more signal transmitting units 20, which is an implementation scheme with the lowest cost, and the on-board unit 60 can be completely replaced by the existing smart phone, which has a three-axis gyroscope, that is, an electronic compass, meanwhile, the system is also provided with a GPS module, an output device 64, a loudspeaker, a large screen, a central processing unit and a clock unit, so that the technical scheme has the lowest implementation cost, only client software needs to be installed on the mobile phone, relevant intersection signals at the end of an instruction sending unit are received, the area where the mobile phone is located is judged in real time, and then the state of a signal lamp of the front intersection is given.
In the early stage, the intersection number is calibrated on a map of a mobile phone or a vehicle-mounted unit 60, the signal state sent by an instruction sending unit 40 is received in real time through a network, areas with different areas are divided on the map according to the intersection density, when a vehicle arrives at one area, the system automatically obtains corresponding signal lamp data from a platform, and then the signal lamp state of the front intersection is obtained after comparison is carried out according to the vehicle direction positioning of a GPS and an electronic compass.
In order to solve the problem that a driver enters a diversion channel and then approaches the road crossing a solid line violation because the shielding of the vehicle fails to recognize the condition of the diversion channel at the intersection in advance, the number of the diversion channels in the line directions of left-turning, straight-going, right-turning and the like can be increased in each group of signals. Or, the number of the adjacent intersection diversion channels is issued in advance by the road information transmitting unit 20, or a second transmitting unit (not shown) is arranged at the position where the vehicle has to pass, the number of the diversion channels in the route direction of left-turn straight-going right-turn is sent in advance, taking the second embodiment as an example, the information sent out by the second embodiment is 52a0b2c1d1, the on-board unit 60 receives the information of the number of the diversion tunnels in each line direction, a is a straight diversion tunnel, the number of the left-turn diversion channels is 0, the number of the left-turn diversion channels is 2, the number of the right-turn diversion channels is c, the number of the turning diversion channels is 1, d is the turning diversion channel, the number of the turning diversion channels is 1, then the data signals are transmitted to the processor 62 to wait for comparison, and meanwhile, the quantity information of the diversion channels is transmitted to the output device, and the quantity and the layout of the diversion channels at the intersection are output in advance for a driver to select the channels in advance.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.

- The road information receiving method as claimed in claim 9,when the road direction of the intersection is measured in advance, wherein the road direction information represents eight directions of east, south, west, north, northeast, northwest, southwest and southeast by letters E, S, W, N, EN, WN, WS and ES, the eight directions are equally marked in the direction of 360 degrees and are respectively eight directions of east, south, west, north, northeast, northwest, southwest and southeast, each direction is divided into 45 degrees, the left and right directions are respectively 22.5 degrees, and when the road direction is measured to be the junction of any two adjacent direction ranges, the road direction is determined to be the positive direction of the two adjacent directions;the states of the signal lamps respectively represent parking and passing by numbers 1 or 0, the line direction comprises straight running, left turning, right turning, turning around and any combination of the directions, letters a, b, c and d respectively represent the line direction, each intersection number is represented by a number or a letter, and a group of complete signal formats are formed as follows: intersection number + road direction information number + line direction number + signal lamp state number;the eight directions divided by the vehicle direction positioning device are equally divided in the 360-degree direction, namely eight directions of east, south, west, north, northeast, northwest, southwest and southeast, wherein each direction is divided into 45 degrees, the left and right directions of a direction line are 22.5 degrees respectively, the vehicle direction positioning device determines the vehicle movement direction through an electronic compass and verifies the driving track by using a GPS (global positioning system) to further confirm the vehicle movement direction;the vehicle direction positioning device determines the moving direction as a positive direction of two adjacent directions when it is determined that the moving direction of the vehicle is a boundary between any two adjacent direction ranges.
