This disclosure is generally directed to systems and methods for avoiding certain undesirable vehicle operations when a vehicle having a dual vehicle propulsion system is parked inside a confined space. For example, it is desirable to avoid operating an internal combustion engine of a hybrid electric vehicle when the hybrid electric vehicle is parked inside a garage because the internal combustion engine may produce undesirable gaseous emissions, particularly during start up. In an example embodiment, this issue is addressed by a computer of the vehicle defining a geofence that encompasses the garage. The computer disables the operation of the internal combustion engine when the hybrid electric vehicle is located inside the geofence but allows operation of an electric motor of the hybrid electric vehicle for moving the vehicle out of the geofence. The computer enables operation of the internal combustion engine when the vehicle has moved outside the geofence.

An engine idle reduction control apparatus includes a first data acquiring unit, a detecting unit, a first determining unit, a control unit, and a second determining unit. The detecting unit is configured to detect a traffic circle, on the basis of traveling environment data acquired by the first data acquiring unit. The control unit is configured to execute an idle reduction, in a case where the first determining unit determines that a control condition for a pre-stop idle reduction control is satisfied. The second determining unit is configured to determine whether a prohibition condition for the pre-stop idle reduction control is satisfied, in a case where the traffic circle is detected. The control unit is configured to prohibit the idle reduction even in a case where the control condition is determined to be satisfied, on a condition that the prohibition condition is determined to be satisfied.

The present disclosure relates to an ISG control system and an ISG control method for a construction machine capable of controlling ISG even in a working state of a construction machine, the ISG control system including: a surrounding environment determinator configured to determine surrounding environment of the construction machine; and a vehicle controller configured to determine whether the construction machine is in a working state or a traveling state based on a determination result from the surrounding environment determinator, wherein the vehicle controller controls an engine based on a preset work ISG condition when it is determined that the construction machine is in the working state, and wherein the vehicle controller controls the engine based on a preset travel ISG condition when it is determined that the construction machine is in the traveling state.

A control system and method are described for controlling a vehicle stop-start system having a stop stage in which an engine of a host vehicle is automatically stopped and a start stage in which the host vehicle engine is automatically restarted after the stop stage. The control system includes an interface configured to receive an input signal including traffic condition information, wherein the input signal includes a vehicle-to-x communication signal or a sensor signal from a host vehicle sensor adaptable to monitor a traffic condition. The control system also includes a controller configured to generate a control signal operative to automatically initiate the start stage of the vehicle stop-start system based on a determination that the traffic condition information of the input signal indicates an impending change in a traffic condition.

Methods and systems are provided for selectively disabling a stop-start function of a vehicle based on a predicted anxiety of a driver of the vehicle upon merging into transverse traffic. In one example, selectively disabling the stop-start function of a vehicle based on a predicted anxiety of the driver of the vehicle includes, when approaching an intersection having a first traffic pattern, disabling a stop-start function responsive to an estimated merging acceleration for the intersection exceeding a threshold acceleration rate of the vehicle.

An apparatus includes a route circuit and a stop-start circuit. The route circuit is structured to estimate a number of charging locations for an energy storage system of a vehicle for a planned route. The stop-start circuit is structured to determine a stop-start strategy for an engine of the vehicle based on the estimated number of charging locations and expected charges to be received by the energy storage system. The stop-start strategy defines a frequency and duration of using the engine in an on-mode during operation of the vehicle along the planned route. The stop-start circuit is further structured to determine that the energy storage system fails to receive an expected charge at one of the charging locations, and update the stop-start strategy to compensate for failing to receive the expected charge by increasing use of the engine in the on-mode during operation of the vehicle along the planned route.

The control device of a vehicle includes a position estimating part configured to estimate a position of the vehicle, and a power output part configured to control the internal combustion engine and the electric motor to output power for running use. The power output part is configured to determine a startup position of the internal combustion engine of the vehicle when the vehicle exits from a low emission zone requesting the internal combustion engine be stopped so that startup positions of internal combustion engines of a plurality of vehicles are dispersed at surroundings of the low emission zone.

An auto-stop start system for a vehicle. The auto-stop start system has a control unit with an auto-stop start function controlling stop and start of an engine of the vehicle, and a control device by which control device the auto-stop start function can be temporarily deactivated by an operator of the vehicle. The control unit is configured to reactivate the auto-stop start function after a predetermined duration of a temporary deactivation. The predetermined duration of the temporary deactivation of the auto-stop start function is selectable by means of the control device.

Systems and methods for improving operation of a vehicle are presented. In one example, a controller may respond to a presence or absence of a prediction of an increase in vehicle speed during a look ahead window. The controller may inhibit or allow automatic engine stopping in response to the presence or absence of the prediction of the increase in vehicle speed during the look ahead window.
