  • Battery voltage threshold adjustment for automatic start and stop system
    Patent number: 7146959
    Abstract: A vehicle engine control having an automatic start and stop feature for idling the engine to maintain the battery charge includes adjustment for the battery voltage threshold at which the engine is started to recharge the battery. Preferably, the adjustment results from use of an ambient air temperature sensor and a look up table in the control that varies the threshold based on a predetermined relationship between battery voltage and ambient air temperature.
    Type: Grant

  • Engine run time change for battery charging issues with automatic restart system
    Patent number: 7036477
    Abstract: An engine control practices a method for engine control in a vehicle control system having an automated start and stop system that keeps a battery charged and an engine temperature in a preselected range, the run time for the engine being extended beyond a preset run time when said control senses that a time interval between start up and the last shut off is shorter than a preset start up time limit.

  • Automatic thermostat mode time limit for automatic start and stop engine control
    Patent number: 7003395
    Abstract: A control system for vehicle engines includes an automatic start and stop idling feature. The control starts engine running in response to detected engine conditions such as oil temperature of battery voltage in at least one mode, and in response to a thermostatic mode by a comfort thermostat in a cabin in at least a thermostat mode of operation. The thermostat mode operation is modified to terminate responses to inputs from the thermostat after an extended period for operation matches programmed threshold representative of no occupation in the area with the thermostat.
