Disclosed is an information and electrical power transmission system. In this system, when required, i.e., when an ignition keyswitch is in an ON state, a plurality of information and electrical power are transmitted from an electrical power supply side to an electrical power receiving side through a signal line, and, at the same time, a plurality of information can be transmitted through the signal line from the electrical power receiving side to the electrical power supply side. When the ignition keyswitch is in an OFF state, information which is required to be always transmitted can be transmitted with a low power consumption, so that the information and electrical power necessary for a vehicle are suitably transmitted.

A sensing apparatus including: a first electrode member; a second electrode member arranged at opposing positions a predetermined distance away and electrically isolated from the first electrode member; and an electric circuit connected to the first and second electrode members. The first and the second electrode members are operatively connected by an impedance formed between the first and the second electrode members in response to existence of a substance to be sensed between the first and the second electrode members. The electric circuit outputs a signal in response to the impedance. The sensing apparatus is applicable for detecting, for example, the level of a liquid in a vessel.
摘要:
Method and apparatus for instantaneously measuring fuel consumption rate and indicating the instantaneously measuring distance traveled per unit fuel amount consumed, i.e., the instantaneous fuel consumption rate of a running vehicle. A signal representing the operating parameter of the internal combustion engine of the running vehicle measured in terms of the amount of fuel being consumed by the vehicle and another signal representing the running speed of the vehicle are separately integrated by first and second integrating circuits, whereby when the integrated value of the first integrating circuit reaches a predetermined value, the integrated value of the second integrating circuit is indicated.
摘要:
Indication of possible vehicle running distance with remnant fuel is accomplished by measuring the fuel amount, the fuel consumption and the running distance and calculating the possible remaining running distance with remnant fuel. The indication is directly based on the current driving condition so that the driver can know the possible running distance with remnant fuel in continued driving under similar conditions. The indication can prevent fuel shortage and also teach a driver economic driving.
摘要:
A fuel consumption measuring device for measuring the amount of fuel consumed by the internal combustion engine of an automobile in which the amount of air drawn into the engine is measured from a signal corresponding to the revolution speed of the engine and another signal corresponding to the amount of gas drawn into the engine whereby to accurately measure the amount of fuel drawn into the engine by virtue of the fact that the ratio between the intake air amount and the intake fuel amount is practically constant at all times.
摘要:
There is provided a fuel consumption measuring device wherein each time the fuel injection valve in a fuel injection system for an internal combustion engine is opened, a first pulse signal is generated whose pulse width corresponds to the duration of the opening of the valve, and the pulse width of the first pulse signal is measured to generate second pulse signals corresponding to the quantity of fuel fed, whereby an exact amount of the fuel consumed or remaining in the fuel tank is stored.
摘要:
An average fuel consumption rate measuring system wherein the distance traveled by a vehicle per unit fuel consumption is computed and indicated to let the driver know the driving conditions of the vehicle and instruct the driver in economical driving. Namely, a first electrical signal is generated for every predetermined distance traveled by the vehicle and the signals are integrated to indicate the total distance traveled, while on the other hand a second electrical signal is generated for every predetermined amount of fuel consumed by the vehicle and the signals are integrated to indicate the total fuel consumption, and one of the integrated value is divided by the other to indicate an average fuel consumption rate.

A system-enabled vehicle entering a crossing warns a driver of the vehicle that a possibility of bumping exists, thereby allowing the driver to brake and stop the vehicle in an emergency in front of the crossing. When the system determines a possibility of bumping with another vehicle entering the crossing exists, the system continuously provides controls for decelerating and stopping the vehicle in a range from a point where the system can decelerate the vehicle in an emergency with time allowance for stopping the vehicle in front of the crossing up to a point in front of the crossing.
