Embodiment Construction

[0020] Attached below figure 1 The present invention will be further described.

[0021] A method for recommending a gear position of an AMT model in a manual mode, comprising the steps of:

[0022] a) When the vehicle starts to run, the TCU checks the driving mode of the AMT, if the driving mode of the AMT is automatic mode, then go to the running step h), if the driving mode of the AMT is manual mode, then go to the running step b); b) TCU Check the shift handle and check whether the function key F on the shift handle has been pressed for more than N seconds, if the function key F has been pressed for more than N seconds, then go to step c), if the function key F has not been pressed N Seconds, then turn to the operation step h); c) ABS system will speed u a Send it to the TCU through the CAN bus, the engine controller sends the engine speed n to the TCU through the CAN bus, and the TCU according to the formula u a =0.377×r×n / i g / i 0 Calculate the speed of the vehicle ...

Abstract

A gear recommending method for an AMT vehicle in a manual mode comprises the following steps that (a) when the vehicle operates, a terminal control unit (TCU) checks the running mode of the AMT vehicle; (b) whether a gear function key F on a gear shifting handle is pressed for more than N seconds or not is detected; (c) the TCU sends the current gear n1 and a recommended gear n2 to a controller area network (CAN) bus; (d) an instrument controller (CBCU) receives the current gear n1 and the recommended gear n2 from the CAN bus; (e) the CBCU judges whether n1 is equal to n2; (f) if n1 is not equal to n2, the CBCU controls an alarm device to give out an alarm after M seconds; and (g) the TCU checks the running mode, and if the manual mode of the AMT is off, the TCU quits from a recommended gear module in the manual mode. By adoption of the steps, in the manual mode of the AMT vehicle, a driver can still choose a proper running gear according to a prompt on an instrument panel.

Description

technical field [0001] The invention relates to a gear position recommendation method for an AMT vehicle in a manual mode. Background technique [0002] In the automatic mode of the AMT vehicle, the driver does not need to operate the shift handle to shift gears. The electronic control unit TCU of the AMT selects the appropriate gear according to the vehicle speed, load, slope, accelerator, etc., and automatically shifts gears. In the manual mode of AMT, the driver needs to operate the shift handle to select the gear. Many drivers are used to driving manual transmissions, and they also like to use manual mode when driving AMT models. When the road conditions are complicated, it is relatively safer to drive in manual mode. [0003] However, the gear selected by the driver in manual mode is not necessarily the most suitable gear. If the vehicle has been running in an inappropriate gear, it will increase fuel consumption and transportation costs, which does not meet the requi...
