Problems solved by technology

[0003] However, these existing methods do not consider various specific conditions of the vehicle during driving, such as real-time engine speed, torque, engine universal characteristic curve, external characteristic curve, optimal operating point curve and other vehicle operating information
Therefore, the gear position obtained according to the existing method is not effectively related to the current driving condition of the vehicle, resulting in low accuracy of the gear position obtained in this way and low fuel economy of the vehicle

Abstract

The invention discloses gear shift prompting equipment and a gear shift prompting method. The gear shift prompting equipment comprises an information collecting device which is used for collecting running information of a vehicle, an optimal rotation speed determining device which is connected with the information collecting device and is used for determining the optimal rotation speed of an engine according to the running information of the vehicle, an optimal gear determining device which is connected with the optimal rotation speed determining device and is used for determining the optimal gear of a gearbox of the vehicle on the basis of the optimal rotation speed, and a prompting device which is connected with the optimal gear determining device and is used for prompting a user to shift to the optimal gear.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to a gear shift prompting device and method for diesel engines. Background technique [0002] During the use of the vehicle, the fuel consumption of the vehicle is an important issue. For a vehicle in the process of driving, the current common method is to determine the appropriate gear for the vehicle according to the driving speed of the vehicle in order to save fuel consumption. This generally requires the driver to have rich experience. Speed ​​gear. In addition, there is currently a method of automatically calculating the appropriate gear through the control system according to the driving speed of the vehicle. [0003] However, these existing methods do not consider various specific conditions of the vehicle during driving, such as vehicle operating information such as real-time engine speed, torque, universal characteristic curve, external characteristic curve, and o...
