Abstract

Systems and methods are provided for actuating a clutch of a manual transmission of a vehicle comprising. An automatic emergency braking (AEB) system is configured to automatically initiate an AEB event and a brake controller is configured to automatically actuate a braking system of the vehicle. A powertrain controller in is configured to monitor vehicle parameters and determine when an engine ofthe vehicle is nearing stall. A clutch control module is configured to actuate a clutch hydraulic master cylinder and actuate the clutch. A vehicle sensor network is configured to detect objects surrounding the vehicle. The AEB system is configured to initiate the AEB event based on detected objects surrounding the vehicle and, when the AEB event is initiated, instruct the brake controller to automatically actuate the braking system and instruct the clutch control module to actuate the clutch when the vehicle is nearing stall.

Description

technical field [0001] The present invention relates generally to vehicle clutches, and more particularly to a method and system for automatically actuating a clutch of a manual transmission of a vehicle during autonomous braking. Background technique [0002] Modern vehicles are often equipped with automatic emergency braking (AEB) systems, which are designed to automatically apply the vehicle's brakes when an imminent collision is detected to avoid a collision as much as possible, if possible, or mitigate if avoidance is not possible. The severity of the collision. On vehicles with an automatic transmission, the AEB system can apply the brakes and bring the vehicle to a complete stop without stalling the engine. Conversely, when the vehicle has a manual transmission, if the brakes are applied to slow the vehicle, eventually the engine will stall unless AEB application is pre-aborted. If the engine stalls, the vehicle may become difficult to control, and the vehicle will ...
