Patent ID: 8115652

Claim:
An apparatus for vehicle driving guide comprising: a traffic condition detection module obtaining a traffic condition; multiple indication lamps being mounted separately on a target road and arranged into multiple lamp blocks; and a signal control module being electrically connected to the traffic condition detection module and the indication lamps and controlling the indication lamps according to a control process based on different traffic conditions to guide drivers in vehicles on the target road, wherein the signal control module comprises multiple sub-control modules corresponding respectively to the lamp blocks and electrically connected to the traffic condition detection module, and each sub-control module electrically connected to the indication lamps in a corresponding lamp block, receiving the traffic condition from the traffic condition detection module and transmitting a coordination signal based on the traffic condition; and a main controller connected to the sub-control modules through a multiplexer and a de-multiplexer, receiving the coordination signals from the sub-control modules, arbitrating conflicts between the sub-control modules and transmitting enable signals respectively and differentially to the sub-control modules to coordinately operate the sub-control modules; wherein each sub-control module comprises: a time counter; a signal controller connected to the time counter and the indication lamps in a corresponding lamp block; and a processor electrically connected to the traffic condition detection module, the multiplexer, the de-multiplexer and the signal controller, receiving the traffic condition from the traffic condition detection module, transmitting the coordination signal based on the traffic condition to the main controller through the multiplexer, transmitting a driving signal to the signal controller in a corresponding sub-control module when receiving a corresponding enable signal from the main controller and controlling the indication lamps in the corresponding lamp block according to the control process.
