An idle reduction system for use with an engine can include a main unit including a controller, and a relay controlled by the controller. The relay can be electrically connected between an ignition switch and an electrical power source for starting the engine. A method of reducing idling of an engine can include connecting an idle reduction system, thereby permitting the system to shut down the engine in response to one or more predetermined conditions, the idle reduction system starting the engine in response to at least one of : a) battery voltage being less than a predetermined level, and b) engine temperature being less than a predetermined level, and the idle reduction system controlling operation of at least one of: an auxiliary air conditioner and an auxiliary heater.

A method and system for anti-idling management for a vehicle including an anti-idling system (AIS) is disclosed. Based on inputs from different sources associated with the vehicle, the AIS determines when anti-idling management should be enabled in order to control the engine of the vehicle. In some embodiments, the AIS includes an AIS battery that can be used to power auxiliary vehicle components when the vehicle is stopped via anti-idling control management.

A remote start system for a vehicle having an engine, and a vehicle data communications bus extending throughout the vehicle may include at least one external temperature sensor coupled to the vehicle data communications bus to sense an external vehicle temperature, and at least one internal temperature sensor coupled to the vehicle data communications bus to sense an internal vehicle temperature. The remote start system may also include a wireless remote control device and a controller coupled to the vehicle data communications bus to start the engine based upon the wireless remote control device and determine an idle time threshold based upon the external temperature. The controller may also stop the engine based upon reaching the idle time threshold or an internal vehicle temperature threshold.

A vehicle, system, and method provide determining whether a thermal risk exists for an occupant of a passenger compartment of a vehicle based on: identifying, via the temperature sensor, that the temperature within the passenger compartment is outside of a safe temperature range, identifying, via an electronic control module, that an engine of the vehicle is not running, and identifying, via the occupant sensor, that an occupant is in the passenger compartment. In response to determining that the thermal risk exists, a controller starts starting the engine via an ignition locking system, closes power-actuated windows of the passenger compartment, locks power-locked doors of the passenger compartment, and activates a heating, ventilation and air conditioning system of the vehicle via a climate control unit. The HVAC maintains the temperature of the passenger compartment within the safe temperature range to safeguard the occupant until return of a responsible party.

A control method capable of variably applying an existing engine-on line includes: a prediction degree calculation unit to predict a degree to which a temperature of a coolant at a current point after the engine is turned off reaches a target temperature by a request of full automatic temperature control (FATC); a factor determination unit to set reference ranges divided based on an extent that the temperature is close to the target temperature, and to determine a factor value for each reference range so that a predetermined existing engine-on line or a predetermined existing engine-off line is varied by required power; and an engine on/off line determination unit configured to determine a corrected engine-on line or a corrected engine-off line by calculating the existing engine-on line or the existing engine-off line and the factor value in the reference range in which a calculation value is positioned.

The present disclosure provides a method in a vehicle, comprising detecting an engine stop opportunity and recording, in a memory, data corresponding to a first engine stop that occurred in response to detection of the engine stop opportunity. The method further includes detecting an engine stop inhibit, and recording, in a memory, data corresponding to a first missed engine stop wherein the first missed engine stop indicates detection of the engine stop opportunity without an engine stop in response to the detection of the engine stop opportunity.

A control unit for a heavy-duty vehicle, where the control unit is arranged to control the vehicle according to a mode of operation selected from at least three different modes of operation, wherein the mode of operation is configurable by a driver via a mode selection device, wherein a first mode of operation is a mode of operation wherein the vehicle is in an inactivated state, wherein a second mode of operation is a stand-by mode of operation where the vehicle is in an active state, and wherein the control unit is arranged to turn off a combustion engine of the vehicle in case a vehicle state meets a pre-determined power-down criterion, and wherein a third mode of operation is a mode of operation where the vehicle is in the active state.

A control method capable of variably applying an existing engine-on line includes: a prediction degree calculation unit to predict a degree to which a temperature of a coolant at a current point after the engine is turned off reaches a target temperature by a request of full automatic temperature control (FATC); a factor determination unit to set reference ranges divided based on an extent that the temperature is close to the target temperature, and to determine a factor value for each reference range so that a predetermined existing engine-on line or a predetermined existing engine-off line is varied by required power; and an engine on/off line determination unit configured to determine a corrected engine-on line or a corrected engine-off line by calculating the existing engine-on line or the existing engine-off line and the factor value in the reference range in which a calculation value is positioned.

The present disclosure provides a vehicle control device including: a fluid circuit, mutually connecting an engine, a vehicle cabin interior heat exchanger for discharging heat into a vehicle cabin interior, and a heat discharging heat exchanger included in a refrigerant cycle in which a refrigerant is compressed and expanded by a compressor, and in which a fluid circulates; and a control unit for controlling the compressor and the engine such that, in a case in which engine warm-up operation ending conditions have not been established and in a case in which predetermined stopping conditions, other than the warm-up operation ending conditions, for stopping engine idling have been established, the compressor is operated while the engine is idling so as to release heat from the refrigerant from the heat discharging heat exchanger and to heat the fluid.

The air-conditioning control device is configured to control an air conditioner for a vehicle having a radiant heater and to output a cancel signal that allows an engine, which has been stopped in response to an idling stop control, to restart. The radiant heater is configured to generate radiant heat to heat an occupant in a compartment of the vehicle. The air conditioner is configured to heat an interior of the compartment using engine cooling water. The air-conditioning control device stops the engine in response to the idling stop control. The air-conditioning control device outputs a cancel signal allowing the engine to restart following the engine having been stopped such that an idling stop time is longer when the radiant heater is operated than when the radiant heater is not operated.
