Embodiment Construction

[0051] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar parameters or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0052] The invention provides a control method and system for the automatic transmission of passenger and freight vehicles, which performs acceleration calibration for different loads of the vehicle to determine the range of ratios between different accelerations and throttle openings, and then determines the shifting speed under different loads; when the system initially works , the controller outputs a vehicle speed corresponding to the initial gear shifting of the gearbox under no load, and when it is detected that the vehicle accele...

Abstract

The invention discloses a control method and a system of an automatic transmission of a van. The method comprises the steps of obtaining the current speed of the van; determining the required gear according to the speed and gear corresponding relation corresponding to different bearing capacities and the current speed of the van; and adjusting the gear to the current gear. The required gear is determined according to the speed and gear corresponding relation corresponding to the different bearing capacities and the current speed of the van, when the bearing capacities are changed, the applicable speed and gear corresponding relation is determined first, and then the current required gear is determined according to the applicable speed and gear corresponding relation and the current speed,so that the problem of the change of the gear application range because the load change to the van is difficult to satisfy by a transmission system is effectively solved, the appropriate gear can be selected by the control method so as to reduce oil consumption, and the service life of the transmission, a clutch and an engine are prolonged.

Description

technical field [0001] The invention relates to the technical field of automatic transmissions, in particular to a control method and system for automatic transmissions of passenger and truck vehicles. Background technique [0002] The automatic transmission can reduce the driver's labor intensity, avoid misoperation, and improve driving safety; in addition, it can simulate the shifting operation of an excellent driver and eliminate the difference in fuel consumption caused by the difference in driver's driving skills; it can also reduce the impact on The driver's driving skills are required to save the cost of driver employment; the above advantages can improve the service life of the transmission, clutch and engine. With the continuous development of automatic transmission technology, automatic transmissions are gradually used in trucks. [0003] However, the load capacity of passenger cars and trucks varies greatly. Especially for trucks, the weight of cargo loaded on tru...
