Hybrid vehicle system

A hybrid vehicle system comprising:

• an engine capable of outputting torque transmitted to a drive wheel;
• a transmission mechanism configured to convert the torque outputted from the engine at a predetermined transmission gear ratio;
• a first clutch mechanism capable of allowing and disallowing power transmission between the transmission mechanism and the drive wheel;
• a motor generator coupled to a power transmission path between the first clutch mechanism and the drive wheel;
• a second clutch mechanism capable of allowing and disallowing power transmission between the motor generator and the drive wheel;
• and
• a forward-reverse travel switching mechanism coupled to a power transmission path between the engine and the transmission mechanism,
• the forward-reverse travel switching mechanism being coupled to a countershaft coupled to the power transmission path between the first clutch mechanism and the drive wheel,
• the forward-reverse travel switching mechanism being configured to switch among
• a forward-travel direct coupling state to directly couple an engine side and a drive wheel side to transmit torque in a direction to cause a vehicle to travel forward,
• a reverse-travel direct coupling state to directly couple the engine side and the drive wheel side to transmit torque in a direction to cause the vehicle to travel rearward, and
• a neutral state to decouple the engine side and the drive wheel side from each other.
