An apparatus responsive to a change in the position of an accelerator pedal for controlling movement of a throttle valve situated within an induction passage. The apparatus includes a control circuit which determines new and minimum values for the position of the accelerator pedal and determines a demand value corresponding to a setting of the position of the throttle valve as a function of the difference between the new and minimum values. The control circuit substitutes the new value for the minimum value when the accelerator pedal remains released and placed at the same position for a predetermined time.

An electronic trip meter for an automotive vehicle comprises an up-down counter, a memory circuit, an adder-subtractor, a display circuit, and other auxiliary circuits. The up-down counter produces a signal indicative of a remaining distance to a goal by subtracting an actually travelled distance from a preset distance between two points for displaying the remaining distance by the display circuit. When the vehicle reaches the goal, the adder-subtractor produces a signal indicative of the actually travelled distance in accordance with the output signals of the up-down counter and the memory circuit in which the preset distance is stored. The adder-subtractor output signal is then fed to the up-down counter for displaying the actual distance between the two points and to the memory circuit for correcting the preset distance whereby a remaining distance to the starting point in a return trip is easily and accurately obtained. The trip meter may be also utilized for a trip beyond the goal.

An electronic trip meter for a motor vehicle comprises an up-down counter, a memory circuit, display circuit, and other auxiliary circuits. The up-down counter produces an output signal indicative of a distance travelled by the vehicle by counting a number of pulses generated each time the vehicle travels a predetermined distance or a distance remaining to an objective point of a predetermined course by subtracting the travelled distance from a preset distance. The counting up and down functions of the up-down counter is manually controlled for compensating for a travelled distance along a wrong course. The output of the up-down counter is fed to the display circuit for displaying a distance indicated by the output signal thereof. A plurality of distances of legs of a predetermined course may be stored in the memory circuit so that each distance is fed to the up-down counter as the predetermined distance.

An electronic trip meter with an alarm for an automotive vehicle comprises a travelled distance sensing circuit, a memory circuit, a modification circuit, comparators, an alarm, first and second counters, a subtractor, a display circuit, and other auxiliary circuits. A plurality of sub distances defined by guide points along a course and a total distance of the course are respectively preset in the memory circuit and the second counter. The second counter output signal indicates a distance remaining to the goal of the course for displaying the remaining distance. The modification circuit output signal indicates a distance shorter than a sub distance while the first counter output signal indicates a distance actually travelled. When the vehicle travells over the distance shorter than the sub distance, the alarm is energized, by means of a comparison of the distances for informing the driver that a next guide point is near. Simultaneously, a distance remaining to the next guide point is displayed for a predetermined period of time.
