Embodiment Construction

[0044]For further understanding of the present invention, now describe in detail below in conjunction with technical scheme and accompanying drawing:

[0045] combined with figure 1 , in the intelligent transportation system, the vehicle can obtain other road information such as surrounding vehicle information, traffic light information, etc., according to these information, the optimal vehicle speed planning controller can solve the optimal vehicle speed. The error compensation controller obtains the commanded vehicle speed based on the optimal vehicle speed and the predicted error, and communicates it to the driver. The energy management controller distributes torque to the vehicle's engine and electric motors based on the driver's acceleration or braking information.

[0046] combined with figure 2 , the technical route can be divided into upper-level control and lower-level control. The upper layer control includes: signal light information model modeling and using the...

Abstract

The invention discloses an intelligent network joint hybrid vehicle formation control method based on a driving style, and relates to the field of intelligent network joint hybrid vehicles. The methodcomprises the following steps of: firstly, using a vehicle networking technology and an intelligent transportation system to obtain real-time information such as front and rear vehicle distance, roadspeed limit, traffic signal, etc., and using particle swarm optimization algorithm to solve an optimal vehicle speed; secondly, combining the error big data obtained through tracking target vehicle speed of the drivers with different driving styles, and using a BP neural network and a compensation algorithm to solve a command speed of a driving assistance system; and finally, controlling the engine and motor torque near the optimal torque through hybrid vehicle energy management. According to the intelligent network joint hybrid vehicle formation control method based on the driving style, theinstruction speed of the driving assistance system is solved, and real-time energy management control is performed on the hybrid vehicle according to the intelligent transportation system and the driving style of the driver, the purpose of improving the road passing capacity and the fuel economy of the vehicle is achieved, and a new direction is provided for the hybrid vehicle in combination withthe intelligent transportation environment and the intelligent assistance driving.

Description
