Abstract

The invention discloses a gear shifting method for a bus. The gear shifting method for the bus comprises the following steps that a) the gear shifting point (V1) of the bus during empty loading is calculated; b) the gear shifting point (V2) of the bus during full loading is calculated; c) the mass coefficient (xi) of the bus, namely, the relation between the actual mass (M) of the bus and the unladen mass (M1) and the full-load mass (M2) is calculated; and d) the actual gear shifting point (V) of the bus is calculated according to the gear shifting point (V1) of the bus during empty loading, the gear shifting point (V2) of the bus during full loading and the mass coefficient (xi) of the bus. According to the gear shifting method for the bus, it can be ensured that oil consumption is reduced as far as possible on the premise that the bus meets the power performance target.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a method for shifting gears of a bus. Background technique [0002] In the field of passenger cars, automatic transmissions are showing a good development trend in the world due to their comfort, safety, environmental protection, energy saving and other advantages. For urban buses, it is generally required to arrive at each station on time within the specified time. Therefore, there are certain requirements for its power performance. consume. [0003] Different from traditional passenger cars, the weight of buses with no load and full load is very different, and the mass of full load can reach 1.5-1.7 times of the mass of no load. Therefore, a single shift curve cannot fully cover the impact of different passenger numbers. difference. If the shift curve can ensure that the vehicle just meets the power target when the vehicle is fully loaded, then the economy will be poor when the ve...
