First Claim
Patent Images
1. A method for determining when to stop an engine in a vehicle having a second power source, the method comprising:
- comparing at least one engine condition to a corresponding predetermined engine condition, thereby generating a first flag;
comparing at least one vehicle system controller condition to a corresponding predetermined vehicle system controller condition, thereby generating a second flag;
comparing at least one second power source condition to a corresponding predetermined second power source condition, thereby generating a third flag; and
stopping the engine when at least one of the flags indicates an engine stop condition.

Abstract
A method is provided for determining when to allow a vehicle engine to be placed in an engine standby mode. Various conditions, such as driver-controlled conditions, vehicle conditions, and energy management conditions, are compared to corresponding predetermined conditions. If at least some of the conditions match their corresponding predetermined conditions, the vehicle engine is allowed to be placed in a standby mode.

11. A method for enabling engine standby in a vehicle having an engine, a motor, and a battery, the method comprising:
-
determining whether at least one engine condition matches a corresponding predetermined engine condition;
determining whether at least one vehicle system controller condition matches a corresponding predetermined vehicle system controller condition;
determining whether at least one second power source condition matches a corresponding predetermined second power source condition; and
enabling engine standby when at least one of the determined conditions matches a corresponding predetermined condition. - View Dependent Claims (12, 13, 14, 15, 16)
