Abstract: A transmitting apparatus of simple circuit configuration is provided as having turn off time (cut off delay time) of an output transistor shortened. The potential of a low-level signal is inputted to an input terminal of a first transistor through a resistor. The potential of a high-level signal is inputted to an input terminal of a second transistor through a resistor. A control circuit is connected to the input terminals of the first and second transistors and when a high-level signal is to be transmitted to the communication line, the control circuit enters a high-impedance state with respect to the input terminal of the first transistor and outputs a low-level signal to the input terminal of the second transistor. When a low-level signal is to be transmitted over the communication line, the control circuit outputs a high-level signal to the input terminal of the first transistor and develops a high-impedance state with respect to the input terminal of the second transistor.

Abstract: This vehicle communication system is suitable for high speed communication with small signal distortion. The communication system for a vehicle includes, provided with charge and discharge that allow a distributed capacitance of a signal line to be discharged by making a stored charge by-pass a pull-up resistor, or causing the distributed capacitance of the signal line 5 to be charged up by making a charge by-pass a pull-up resistor.

Abstract: An auto cruise control method and device for a vehicle such as a motorcycle allows the vehicle to operate at a constant set speed while avoiding acceleration or deceleration shock after the auto cruise device is temporarily or permanently operated to change the vehicle speed. Therefore, a smoother ride is provided. Also, a final acceleration change rate can be corrected by considerating factors such as slope, wind, load weight, variation in engine output and non-linearity of engine torque characteristics. Moreover, when the speed is to be changed or when operation of the auto cruise device is to be resumed, the speed of the vehicle can be smoothly shifted.
