Embodiment 1
[0032] In the first aspect, the present invention provides the first aspect. The present invention provides a conventional vehicle intelligent shift control method, including:
[0033] Get the vehicle speed range and current speed;
[0034] According to the speed range of the whole vehicle, the gear position of the gearbox is judged by the ratio of the engine speed to the rear shaft speed of the gearbox;
[0035] According to the gear position of the gearbox and the current speed of the vehicle, the smart shift reminder will be provided through the instrument.
[0036] When it is detected that the current vehicle speed is greater than V1 and the ratio is less than i1, the instrument does not change; if the ratio is greater than i1, the instrument prompts for an upshift.
[0037] When it is detected that the current vehicle speed is greater than or equal to V2 and less than V1, and the ratio is less than i1, the instrument prompts for downshifting; if the ratio is greater than...
Embodiment 2
[0049] In a second aspect, the present invention provides an intelligent gear shift control system for a conventional vehicle, which implements the above-mentioned intelligent gear shift control method for a conventional vehicle.
[0050] specific,
[0051] Such as figure 2 As shown, in this embodiment, the specific working process or content of a conventional vehicle intelligent shift control method is:
[0052] The CAN bus instrument first detects the speed range of the vehicle, sets the current speed as V, and through the table look-up method,
[0053] On the one hand, when the vehicle speed V≥V1 is detected, the gear position of the transmission is judged by the ratio i of the engine speed to the rear shaft speed of the gearbox. If the ratio i
[0054] Further, when the vehicle speed V1>V≥V2 is detected, the gear position of the gearbox...

Abstract
The invention discloses an intelligent gear shifting control method for a conventional vehicle. The method comprises the steps that the vehicle speed interval and the current vehicle speed of the whole vehicle are obtained; according to the whole vehicle speed interval, the gear of the gearbox is judged according to the ratio of the engine rotating speed to the gearbox rear shaft rotating speed; and according to the gear of the gearbox and the current vehicle speed, intelligent gear shifting reminding is conducted through an instrument. The method is realized based on a CAN bus instrument, the problem of long-time neutral-gear sliding of a conventional vehicle is solved, the vehicle runs more safely, and the braking function of an engine is effectively utilized.
Description
technical field [0001] The present invention relates to the technical field of auxiliary driving control of conventional vehicles, in particular to an intelligent shift control method and system for conventional vehicles. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Following the country's energy-saving and emission-reduction requirements, the country has also sounded the alarm of power cuts. How to minimize energy consumption and maximize economic benefits has become the main goal of national scientific research projects. Although the development of new energy is in full swing, fuel vehicles still have a relatively large proportion in China. Drivers generally judge the rationality of gears based on their own experience to achieve fuel-saving vehicles. Various companies have also held energy-saving competitions to promote vehicles to sa...
