Embodiment Construction

[0052] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0053] The present invention uses a truth table to combine and judge the R gear / N gear / D gear of the new energy vehicle, introduces the influence of vehicle speed / motor speed / motor rotation direction / motor torque on the shifting process, and switches from N gear to D gear / In the case of R gear, the judgment of different modes is added, there is no conditional restriction in the process of switching from D gear / R gear to N gear, and the method of whether to capture the N gear signal is perfected in the process of fast gear switching.

Abstract

The invention discloses an automobile gear management control method and device, and relates to the technical field of overall automobile control. The method includes the following steps that after a gear shifting signal of an automobile is received, whether the current gear shifting signal is a R gear, or an N gear or a D gear is determined to obtain the only effective current gear shifting signal; after the current gear shifting signal is obtained, the automobile condition is detected to obtain an automobile speed signal, a motor rotating speed signal, a motor rotating direction signal and a motor torque signal; according to the current shift gearing signal, the automobile speed signal, the motor rotating speed signal, the motor rotating direction signal and the motor torque signal, whether a gear is switched is judged; according to the judgment result, the corresponding gear shifting operation is executed. The gear signal judging and switching processes are reasonably processed to ensure safety of overall automobile traveling.

Description

technical field [0001] The invention relates to the technical field of vehicle control of automobiles, in particular to a control method and device for automobile gear management. Background technique [0002] In recent years, environmental pollution has become increasingly serious, and air quality has continued to deteriorate. The exhaust gas of traditional fuel vehicles contains a large amount of pollutants, which is one of the causes of smog. New energy vehicles can reduce the emission of vehicle exhaust pollutants, especially pure electric vehicles can drive without pollution, so promoting the research and development of new energy vehicles has become a hot topic in recent years. [0003] The vehicle controller is the core control component of new energy vehicles, and the gear position signal judgment and switching process are its important control parts, which directly reflect the driver's driving intention and are related to the gears sent by the vehicle controller to ...
