Abstract

The invention discloses a regional control method for bus stops of hybrid buses based on intelligent traffic information. The method comprises the steps of: step 1, collecting the speed, the throttleopening, the distance from the next bus station and the battery power information of a bus according to a sampling period; step 2: carrying fuzzification on the speed, the throttle opening, the distance from the next bus station and the battery power information of the bus, and then performing fuzzy inference calculation, defuzzification and obtaining a control permission degree; step 3, when thecontrol permission degree is {low}, allowing the bus to drive according to the original driving state; when the control permission is {medium, high}, disconnecting an engine of the bus from a clutch of a transmission to maintain torqueless transmission between the engine and the transmission and keeping the engine turned off; keeping the transmission running in a low gear position, allow downshifting, prohibiting the upshift; and using a drive motor to drive the bus separately and limiting the output power thereof. Accordingly, the comprehensive energy consumption and the service life of the clutch are improved.

Description

technical field [0001] The invention relates to the field of adaptive control of a hybrid power bus to a bus stop area, and more specifically, the invention relates to a hybrid power bus bus stop area control method based on intelligent traffic information. Background technique [0002] Normally, the hybrid electric bus controls the engine, drive motor and automatic transmission assembly according to the accelerator, brake, vehicle speed and other information. Driving environment information will bring problems such as short-distance start / stop of the engine, unnecessary shifting, etc., which deteriorate the energy consumption of the vehicle, the service life of the clutch assembly components, and the ride comfort. Therefore, it is beneficial to improve the comprehensive performance of the existing system to introduce the real-time information of intelligent transportation (ITS) and integrate the information for more reasonable control. [0003] In view of this, the present...
