To be more specific, the inertial sensor 7 is locked on the left side of the cross tube 255 in the vehicle width direction (so that the driver is sitting on the motorcycle). The right hand is the right side and the left hand is the left side), so that the inertial sensor 7 is disposed adjacent to the air inlet 811 of the air filter 8 , that is, the inertial sensor 7 and the inlet of the air filter 8 The air inlet 811 is located on the same side in the vehicle width direction. To be more specific, the inertial sensor 7 is located below the air inlet 811 of the air filter 8; the signal connection port 7a of the inertial sensor 7 is It is also opened toward the left side of the vehicle body, which means that the signal transmission line connector 7b and the signal transmission line 7c of the inertial sensor 7 are extended from the left side of the vehicle body toward the rear of the central vehicle body cover 67, and then connected with the locomotive 1 The main wiring (not shown in the figure) is tied together, so that the inertial sensor 7 can transmit the sensed information to the vehicle control center (ECU) as a reference for driving control, which on the one hand can facilitate the The signal transmission line connector 7b is connected and detached from the signal connection port 7a, and on the other hand, it can facilitate the wiring trend of the signal transmission line 7c; through the above configuration, the inertial sensor 7 is configured on the locomotive 1 body Approaching the center, it means that the inertial sensor 7 is arranged close to the center of gravity or the center of gravity of the locomotive 1 body; more specifically, the inertial sensor The sensor 7 is disposed on the cross tube 255 behind the central body cover 67 of the body cover unit 6 and below the driver's seat 31 of the seat cushion 3.

The actual driving status information is transmitted to the vehicle control center (ECU), thereby improving driving safety. What is more important to mention is that when the locomotive 1 is running, the cylinder part 41 of the power unit 4 explodes and operates. The generated negative pressure suction draws most of the fresh cold air from the outside through the vent 671 of the central body cover 67, and then enters the air filter 8 through the air inlet 811. Therefore, when the power unit 4 After the cylinder part 41 explodes and operates, an air flow can be formed from the central body cover 67 toward the rear of the vehicle body, which means that a flow of fresh cold air from the outside can be formed behind the central body cover 67 to blow and blow The inertial sensor 7 and the power unit 4 are dissipated to prevent the inertial sensor 7 from being affected by heat, thereby ensuring the usability and sensing accuracy of the inertial sensor 7 .
