Problems solved by technology

While some systems, such as the engine controller, can be designed to handle a drop in battery voltage, other vehicle systems, such as the transmission controller or other controllers, may not be as robust
These other controllers may go into a reset mode of operation and / or cause other drivability issues when the battery voltage drops during an auto start event

Embodiment Construction

[0018] The engine control module and starter selectively start and stop the vehicle's engine in response to vehicle start and shutdown commands from an operator (eg, turning an ignition switch or starter button "on" or "off"). The control module may also automatically initiate an auto-stop event or an auto-start event between a vehicle start command and a vehicle shutdown command during the "on" state of the ignition key.

[0019] For example, the control module may selectively initiate an auto-stop event and shut down the engine when the vehicle is stopped while the driver is applying pressure to the brake pedal and / or other enabling conditions exist. For example, the control module may selectively initiate an auto-start event and restart the engine when the driver removes pressure from the brake pedal and / or other enabling conditions exist.

[0020] Systems and methods according to the present invention include an ultracapacitor system to assist the battery during an auto st...

Abstract

A system includes a supercapacitor and a battery system including a battery, a supercapacitor, a DC-DC converter, a first temperature sensor to sense the temperature of the battery, a second temperature sensor to sense the temperature of the supercapacitor, and a A third temperature sensor for sensing the temperature of the DC-DC converter. An automatic stop / start module is configured to selectively stop and restart an engine of a vehicle when an ignition system is turned on based on an operating parameter. the temperature sensing module is in communication with the automatic stop / start module and is configured to determine a difference between the temperatures sensed by the first sensor, the second sensor, and the third sensor and selectively disable the automatic stop / start module based on the differences .

Description

technical field [0001] The present invention relates to control systems for vehicles, and more particularly to systems and methods for monitoring the temperature of components of ultracapacitor systems in automatic stop / start systems. Background technique [0002] The background description provided herein is for the purpose of generally presenting the context of the disclosure. The work of the presently named inventors is neither expressly nor implicitly admitted to the extent that it is described in this background section, and that aspects of the description that might not otherwise constitute prior art at the time of filing prior art that contradicts the present invention. [0003] Internal combustion engines combust a mixture of air and fuel within cylinders to drive pistons, which produces drive torque. The air flow into the gasoline engine is regulated via a throttle valve. More specifically, the throttle valve adjusts the throttle area, which increases or decrease...
