VEHICLE IDLING STOP CONTROL METHOD AND VEHICLE IDLING STOP CONTROL DEVICE
A vehicle idling stop control device has switches that detect an operation of opening a driver's door and an unbuckling of a driver's seat belt as disembarkation operations by a driver. When a disembarkation operation performed by the driver is detected during an idling stop, the idling stop is cancelled and the engine is restarted upon detecting a disembarkation operation performed by a driver during the idling stop. Also, restarting of the idling stop is prevented due to ending of the disembarkation operation performed by the driver until after the vehicle starts traveling. Thus, unnecessary automatic stopping and automatic restarting of the engine are thereby avoided when the vehicle sets off without the driver actually exiting the vehicle.
REMOTE START SYSTEM AND METHOD FOR A WORK MACHINE
A remote start system and method for a work machine wherein the system comprises a communication device, an engine starter subsystem, a fluid pressure sensor, and a controller. In a first step, controller receives a wake signal from the communication device, The controller then confirms the lock status of a safety lock on the work machine and outputs an engine start signal to the engine starter subsystem upon confirming the lock status. The controller then receives a fluid pressure signal from the fluid pressure sensor, and outputs an engine stop signal if the fluid pressure signal is below a predetermined threshold after a specified timeframe.
Walk-away vehicle shutdown
A vehicle includes an engine, a park assist system, a passenger detection system configured to detect at least one passenger, and a processing device. The processing device initiates a shutdown sequence when no passengers are present in the vehicle. The shutdown sequence includes commanding the park assist system to park the vehicle and turning off the engine after the vehicle is parked.
Cold temperature engine start strategies
A method of starting a vehicle may include, in response to an expected driver entry, stroking a clutch configured to couple an engine to an electric machine for a predetermined time period. The method may further include, in response to an engine start request received during the predetermined time period, providing power to the electric machine to spin the electric machine at a speed at least equal to a target engine cranking speed.

SYSTEM AND METHOD FOR STARTING AN ENGINE
Methods and systems for operating an engine with an electrically heated catalyst and an electrically driven compressor are described. In one example, the electrically driven compressor and the electrically heated catalyst are activated before an engine start so that vehicle emissions may be reduced more efficiently at engine starting and thereafter.
Methods to identify missed engine stops and serviceability
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.

Control device for automatic transmission
A control device for an automatic transmission includes a parking lock mechanism configured to lock/unlock rotation of a power transmission shaft by setting a parking rod at locked/unlocked position when the automatic transmission is in a parking range or in other ranges, a parking drive mechanism configured to set the parking rod at the unlocked position by supplying hydraulic pressure, a hydraulic pressure control valve configured to intercept the hydraulic pressure supply to the parking drive mechanism when power is supplied thereto, and supply the pressure when power is not supplied thereto, a regulating mechanism configured to regulate the movement of the parking rod at the locked position, and a controller configured to, when the parking rod is at the locked position, maintain supply of power to the valve, while an engine speed is higher than a given value, after power of a vehicle is turned OFF.
EXHAUST HEATING SYSTEM FOR MOTOR VEHICLES POWERED BY AN INTERNAL COMBUSTION ENGINE
An exhaust gas heating system and method for rapidly heating an exhaust gas produced by an internal combustion engine upstream from a catalytic converter. The exhaust gas heating system includes a heating element in the form of a multi-layer ceramic heater that is capable of heating to 1800° F. within 4 to 8 seconds to rapidly increase the temperature of the exhaust gas passing through an exhaust pipe during a cold start phase of the ICE. A control system is programmed to activate and deactivate the heating element. Rapid heating of the ICE exhaust gas allows the catalytic converter to be more efficiently and completely clean and purify the exhaust gas during the cold start phase of the ICE.
