Intelligent driving vehicle accelerated speed tracking control system

Abstract

The invention relates to an intelligent driving vehicle accelerated speed tracking control system and belongs to the technical field of intelligent vehicle control. The problem that the intelligent driving vehicle accelerated speed cannot be accurately tracked in the prior art is solved. The system comprises an upper computer module used for calculating estimated traveling resistance Fd accordingto accelerated speed compensation quantity delta a and calculating and obtaining engine controlled quantity and braking controlled quantity according to Fd, a longitudinal controller module used for generating an engine control command and a braking control command according to the engine controlled quantity and the braking controlled quantity, an electronic control drive module used for receivingand executing the engine control command, an electronic control braking module used for receiving and executing the braking control command, and a vehicle-mounted sensor module used for acquiring current vehicle speed information and historical vehicle speed information of an intelligent driving vehicle and sending the current vehicle speed information and the historical vehicle speed informationto the upper computer module, and the upper computer module calculates and obtains the accelerated speed compensation quantity delta a. The intelligent driving vehicle accelerated speed is accuratelytracked.
