Abstract

A vehicle includes a body frame, an engine, a transmission, an injector, an engine controller, and a transmission controller. The body frame supports three or more wheels. The engine is attached to the body frame. The transmission is attached to the body frame and changes a torque from the engine and outputs a resulting torque. The injector is disposed on or above the engine, and supplies fuel to the engine. The transmission controller is configured or programmed to control a gear position of the transmission. The engine controller and the transmission controller are spaced apart from each other.

First claim

What is claimed is:

1 . A vehicle comprising:
a body frame supporting three or more wheels; an engine attached to the body frame; a transmission that is attached to the body frame and changes torque from the engine and outputs a resulting torque; an injector that is disposed on the engine and supplies fuel to the engine; an engine controller configured or programmed to control the injector; and a transmission controller configured or programmed to control a gear position of the transmission; wherein the engine controller and the transmission controller are spaced apart from each other.

2 . The vehicle according to claim 1 , wherein the transmission controller is disposed higher than the engine.

3 . The vehicle according to claim 1 , further comprising a seat on which a driver sits, wherein the seat is supported by the body frame, and the transmission controller is disposed higher than the seat.

4 . The vehicle according to claim 1 , wherein the transmission controller is disposed higher than the transmission.

5 . The vehicle according to claim 1 , further comprising:
a battery that supplies current to each of the engine controller and the transmission controller; and a wire harness including a first end connected to the battery, and a second end connected to the transmission controller; wherein the engine controller is electrically connected to a connecting point between the first end and the second end of the wire harness.

6 . The vehicle according to claim 5 , further comprising:
a power steering system; and a steering controller configured or programmed to control the power steering system; wherein the battery supplies current to the steering controller; and the steering controller is electrically connected to the connecting point.

7 . The vehicle according to claim 6 , wherein the wire harness includes:
a first wire connecting the steering controller and the connecting point; a second wire connecting the engine controller and the connecting point; and a third wire connecting the transmission controller and the connecting point; the current supplied to the transmission controller and the current supplied to the steering controller are each greater than the current supplied to the engine controller; an electrical resistance of the first wire is less than an electrical resistance of the second wire; and an electrical resistance of the third wire is less than the electrical resistance of the second wire.

8 . The vehicle according to claim 6 , wherein the wire harness includes:
a first wire connecting the steering controller and the connecting point; a second wire connecting the engine controller and the connecting point; and a third wire connecting the transmission controller and the connecting point; the current supplied to the transmission controller and the current supplied to the steering controller are each greater than the current supplied to the engine controller; the first wire is shorter in length than the second wire; and the third wire is shorter in length than the second wire.

9 . The vehicle according to claim 8 , wherein a length of the second wire is 1, a length of the third wire ranges from 0.2 to 0.8, and a length of the first wire ranges from 0.1 to 0.4.

10 . The vehicle according to claim 1 , further comprising a speed sensor that detects a speed of the vehicle, wherein the transmission controller is configured or programmed to acquire at least speed information from the speed sensor.

11 . The vehicle according to claim 1 , further comprising a gear position sensor that detects the gear position of the transmission, wherein the transmission controller is configured or programmed to acquire at least gear position information from the gear position sensor.

12 . The vehicle according to claim 1 , wherein the transmission is disposed in front of the engine.

13 . The vehicle according to claim 1 , wherein the engine and the transmission are separate from each other.
