Abstract

The invention relates to manual transmission and engine speed match using a transmission input shaft speed sensor. Specifically, an engine speed matching system for a vehicle with a manual transmission includes a sensor that senses an input shaft speed of the manual transmission during a shift. A control module receives the input shaft speed, determines an engine speed, determines a desired engine speed based on the input shaft speed and the engine speed, and adjusts the engine speed based on the desired engine speed and the input shaft speed before the shift is completed.

Description

Technical field [0001] The present invention relates to manual transmission systems and methods, and more particularly to engine speed matching in manual transmission systems and methods. Background technique [0002] The background art description provided here is used to generally introduce the background of the present invention. The work of the currently signed inventors to the extent described in the background technology section, and the aspects of the prior art in this description that do not constitute the prior art at the time of application, are neither expressly nor impliedly recognized as being related to the present invention. Conflicting existing technology. [0003] In a motor vehicle with a manual transmission, the driver usually actuates the clutch pedal to disengage the clutch. When the clutch is disengaged, the driver uses the gear shift fork to select the desired transmission gear. For example, the driver can select a higher gear (that is, during an upshift) ...
