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.

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.

In a case where a determination is made, after an engine is started based on a remote operation, that an ambient environment of a vehicle is not a predetermined appropriate environment based on a detection value from an ambient environment detection sensor configured to detect the ambient environment of the vehicle, the engine is stopped. As a result, it is possible to suppress a deterioration of an environmental state around the vehicle or an occupant cabin. As a result, it is possible to take more appropriate measures when the engine is started based on the remote operation.

In a case where an engine is started based on a remote operation, a limitation condition for limiting an engine start is tightened or a stop condition after the engine is started is relaxed, as compared to a case where the engine is started based on a switch operation in an occupant cabin. That is, it is difficult to start the engine when the engine is started based on the remote operation, and it is easy to stop the engine when the engine is started based on the remote operation. As a result, it is possible to take more appropriate measures when the engine is started based on the remote operation.

Methods and systems are presented for improving performance of a vehicle operating in a cruise control mode where a controller adjusts torque output from a vehicle to maintain vehicle speed within a desired range. The methods and systems include adapting a vehicle dynamics model and a vehicle fuel consumption map that provide input to nonlinear model predictive controller.

A device and method automatically switches off and starts a drive machine in a motor vehicle. The device includes a sensor unit for sensing a noise level and/or a vibration level of the environment of the motor vehicle and an electronic control unit for controlling an engine start-stop automatic system. The signals of the sensor unit are captured and are compared with at least one defined threshold value. The drive machine is automatically switched off when a predefined condition exists. The drive machine, having been automatically switched off, is automatically started again at the latest when the signals of the sensor unit exceed the at least one defined threshold value.

A stop-start control system for a vehicle includes a camera disposed at the vehicle and having a field of view exterior and forward of the vehicle. A control includes an image processor operable to process image data captured by the camera. Responsive to image processing of captured image data, the control determines the presence of a stopping area ahead of the vehicle and being approached by the vehicle. Responsive to determination of the presence of the stopping area ahead of the vehicle and being approached by the vehicle, and responsive to determination that the driver of the vehicle releases the accelerator pedal of the vehicle so the vehicle is coasting toward the determined stopping area, the control causes the engine to at least partially shut off.

Systems and methods for operating an engine that may be rotated by an electric machine during engine starting are described. In one example, an amount of electric current that is available to rotate the engine via the electric machine may be adjusted in response to an indication that a vehicle that includes the engine may be parked in a geographical area that may be flooded.

What is described is a system for controlling an engine of a vehicle. The system includes a gear shifter having a gear selection sensor configured to determine a selected gear position. The system also includes a proximity sensor configured to detect object data within a predetermined area of the vehicle. The system also includes a controller coupled to the gear shifter and the proximity sensor and configured to control the engine based on the selected gear position and the object data.

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.
