Problems solved by technology

Unmanaged requests from various driver commands and vehicle components may undesirably disable, dedisable, and / or cause repeated cycling of auto start-stop functionality and may introduce potentially unwanted or redundant ICE The need to start and stop, which in turn can create a perception of less-than-optimal performance
In particular, untimely steering commands (such as steering angle, torque and power demands, etc.) may prevent or disable autostop and may disinhibit or enable autostart

Abstract

The invention discloses a hybic vehicle with an auto stop start controller. The hybrid electric vehicle includes a combustion engine, and an electric machine and storage battery coupled to one or morecontroller(s) configured to respond to various signals from a driver and vehicle components. In response, such controller(s) enable an automatic or auto ICE start stop capability that is managed foroptimal HEV lifecycle operation, and fuel economy and efficiency. The controller(s) automatically start and stop the ICE in response to one or more of a torque demand signal, a vehicle speed signal, asteering torque power signal, and a brake signal. The controller(s) inhibit automatic stop of ICE responsive to the steering torque power exceeding a stop threshold, and in contrast initiate or enable automatic start responsive to the steering torque power exceeding a start threshold. The start threshold is calibrated and adjusted to exceed the stop threshold by a stability factor that is predetermined and / or adjusted by the controller(s).

Description

technical field [0001] The present disclosure relates to systems and methods for automatic engine stop-start of hybrid electric vehicles. Background technique [0002] A hybrid electric vehicle (HEV) typically includes an internal combustion engine (ICE) coupled to an electric machine or motor / generator (M / G), and includes various other components including an ICE automatic start-stop controller. Such HEVs may also include a steering unit and related components, which may be manually operated and / or may include electronic and electric power steering units. Typically, ICE auto stop-start conditions are configured for micro-hybrid operation, mild-hybrid operation, and conventional hybrid operation (these terms are used to describe various modes of operation), the ICE auto-stop-start conditions are configured as Manages fuel efficiency and economy and the HEV's responsiveness to driver commands and power demands from HEV components during various modes of operation. said oper...
