Abstract
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.
Claims24
A remote start system of a work machine, the work machine comprising an engine, the remote start system comprising:
- a communication device configured to receive a remote start signal from a remote device, the communication device outputting a wake signal upon receiving the remote start signal;
- an engine starter subsystem configured to initiate an engine start;
- a first fluid pressure sensor for sensing a first fluid pressure on a first work machine subsystem;
- a second fluid pressure sensor for sensing a second fluid pressure on a second work machine subsystem;
- and
- a controller having a non-transitory computer readable medium with a program instruction to remotely start the work machine, the program instructions when executed causing a processor of the controller to:
- receive the wake signal;
- once the wake signal is received, confirm a lock status of a safety lock of the work machine, to initiate the engine start;
- output an engine start signal to the engine starter subsystem upon confirming the lock status;
- receive a first fluid pressure signal from the first fluid pressure sensor and a second fluid pressure signal from the second fluid pressure sensor after the engine start;
- and
- output an engine stop signal if one of the first fluid pressure signal is below a first predetermined threshold and the second fluid pressure signal is below a second predetermined threshold after a specified timeframe.
A method of remotely starting a work machine, the work machine comprising an engine, the method comprising:
- receiving a remote start signal by a communication device from a remote device;
- outputting a wake signal by the communication device upon receiving the remote start signal;
- receiving the wake signal by a controller;
- once the wake signal is received confirming a lock status by the controller of a safety lock of the work machine;
- outputting an engine start signal to an engine starter subsystem upon confirming the lock status to initiate the engine start;
- monitoring a first fluid pressure signal from a first fluid pressure sensor and a second fluid pressure signal from a second fluid pressure sensor after the engine start, the first fluid pressure sensor sensing a first fluid pressure on a first work machine subsystem and the second fluid pressure sensor sensing a second fluid pressure one a second work machine subsystem;
- and
- outputting an engine stop signal if one of the first fluid pressure signal is below a first predetermined threshold and the second fluid pressure signal is below a second predetermined threshold after a specified timeframe.
