Abstract

The invention relates to a method for controlling an engine start and stop strategy based on signal lamp information and a system for executing the system. Bluetooth connection is established through a signal lamp Bluetooth transceiver positioned on a traffic signal lamp and a vehicle-mounted Bluetooth system positioned on a vehicle, so that the orientation of the vehicle relative to the signal lamp is determined; the state and the time of the signal lamp are read, so that the start and stop strategy of an engine is controlled through a judging and decision-making system positioned in a vehicle controller based on engine start and stop control logics. Through the method and the system provided by the invention, the distance between the vehicle and a crossroad, the orientation and the information of the signal lamp can be determined; the engine stop time is prolonged, unnecessary short start-stop energy consumption is reduced to obtain an extra energy-saving effect, and the driving comfort is improved.

Description

technical field [0001] The invention relates to the technical field of controlling engine start and stop, in particular to a method and device for controlling engine start and stop based on signal lamp information through a Bluetooth positioning system. Background technique [0002] Engine start and stop has gradually become a function of advanced conventional vehicles. The realization of its function is based on certain driver operation rules. For example, when the vehicle speed is zero, the driver releases the accelerator, steps on the brake pedal, and the gear is in neutral, the engine stops running; when the driver puts the gear on and releases the brake pedal, the engine ignites and starts. Using this engine start-stop function, the fuel-saving effect of the car can generally reach 4%-6%. [0003] Hybrid vehicles also have an engine start-stop function. The general strategy is that when the vehicle brakes, and when the vehicle speed is lower than a certain speed, the ...
