Commercial vehicle manual transmission gear shifting reminding control method and system

Abstract

The invention discloses a commercial vehicle manual transmission gear shifting reminding control method and system, and relates to the field of vehicle commercial vehicle driving. The method comprisesthe steps that on the basis of vehicle working condition information, the corresponding relation among the gear, the engine rotating speed and the accelerator pedal opening degree on the premise of low fuel consumption is obtained through calculation; the current engine rotating speed of a vehicle is acquired in the running process of the vehicle; a target gear and a target accelerator pedal opening degree are acquired according to the obtained engine rotating speed and based on the corresponding relation among the gear, the engine rotating speed and the accelerator pedal opening degree; andbased on the current gear, the target gear, as well as the current accelerator pedal opening degree and the target accelerator pedal opening degree, gear shifting reminding and / or accelerator adjusting reminding is conducted. According to the commercial vehicle manual transmission gear shifting reminding control method and system, a driver is guided to control an engine within the economic rotating speed range through gear shifting reminding and accelerator adjusting reminding, the output effect of the engine is brought into play to the maximum extent, and the purposes of reducing oil consumption and improving the dynamic property of the vehicle are achieved.

Description

technical field [0001] The invention relates to the field of driving of automobiles and commercial vehicles, in particular to a method and a system for reminding control of manual transmission of manual transmissions of commercial vehicles. Background technique [0002] The manual transmission is a manual transmission device of the car, which is used to change the speed and torque transmitted from the engine to the driving wheel by manual control, and can be used in various working conditions such as starting in place, climbing, turning, and accelerating. , so that the car can obtain different traction and speed, and at the same time make the engine work within a more favorable range of operating conditions. [0003] At present, the group of commercial vehicle drivers is younger. Due to lack of experience, they are often troubled by not knowing how to properly standardize shifting while driving, and the problem of inaccurate timing of shifting during driving occurs, resultin...
