Control system for internal combustion engine

A control system for an internal combustion engine comprising:

• a reverse command generating means generating a reverse command for switching a running direction of an internal combustion engine drive running equipment driven by a two cycle internal combustion engine and running,
• a reverse processing means executing a reverse process necessary for reversing a rotative direction of the internal combustion engine based on the reverse command that the reverse command generating means generates,
• a rotative direction detection means generating rotation detection signals of which states are different at each time when the internal combustion engine is forwardly and reversely rotated and detecting the rotative direction of the internal combustion engine from a state of the rotation detection signal,
• a reverse failure determining means determining that reversing of the internal combustion engine is failed when the rotative direction detected by the rotative direction detection means does not correspond to the rotative direction commanded by the reverse command generating means, and
• an internal combustion engine drive control means controlling the internal combustion engine so that running speed of the running equipment is restricted to a slow speed when the failure of reversing of the rotative direction is determined by the reverse failure determining means.

A control system for an internal combustion engine comprising:

• a reverse command generating means generating a reverse command for switching a running direction of an internal combustion engine drive running equipment running in such a way that motive power of a two cycle internal combustion engine is transmitted to a driven part via a transmission system,
• a reverse processing means executing a reverse process necessary for reversing a rotative direction of the internal combustion engine based on the reverse command that the reverse command generating means generates,
• a rotative direction detection means generating rotation detection signals of which states are different at each time when the internal combustion engine is forwardly and reversely rotated and detecting the rotative direction of the internal combustion engine from a state of the rotation detection signal,
• a reverse failure determining means determining the failure of reversing of the internal combustion engine when the rotative direction detected by the rotative direction detection means does not correspond to the rotative direction commanded by the reverse command, and
• a transmission system control means controlling the transmission system so that transmission of the motive power from the internal combustion engine to the running equipment is cut when the failure of reversing of the rotative direction is determined by the reverse failure determining means.
