Abstract

PURPOSE:To simplify a speed increasing operation, by generating an acceleration signal and increasing the speed of a vehicle by operating a resuming switch again, when a timing circuit is in operation. CONSTITUTION:When a resuming switch SW2 is closed, a timing circuit 91 of an acceleration signal generating circuit 90 provided with the timing circuit is operated for a prescribed time. When the switch SW2 is closed in the course of its operation, the circuit 91 generates an L level signal and an output of an OR gate 92 becomes an L level. This L level signal turns off a transistor T1 and turns on an FETF1, therefore, reference potential Vr is applied to the base of an FETF2. This source voltage VM becomes VM=Vr, therefore, a comparator CM compares the divided voltage VX with Vr. In this case, since VX>Vr is set, an output of the comparator CM becomes an H level, a control solenoid SL1 of an actuator 50 is turned on, the opening of a throttle becomes large, and the speed is accelerated. When the switch SW2 is opened at the time point of reaching a desired speed, a vehicle is shifted to constant speed running.

−１１４作動させγｌ、ば増速が可能である。Usually, this type of device detects the current vehicle speed as a number of pulses and obtains an analog voltage proportional to the number of pulses as a vehicle speed signal. The driver reaches the desired vehicle speed7
At this time, the vehicle speed signal at that time is set (stored) in the memory circuit by operating the constant speed driving center switch. The speed control device converts the set vehicle speed signal to one base of the comparison circuit.
4. Based on the difference between it and the current vehicle speed, the difference is 0 and 7. In this type of device, which adjusts the opening degree of the throttle valve in the direction of 2, when one car is running at a constant speed, if the driver continues to hold down the constant speed running set switch and then continues to close the set switch, the vehicle will come to a stop. It has a so-called 1φ deceleration set function that gradually lowers the vehicle, memorizes the vehicle speed of opening and opening when the set switch is opened, and shifts to constant speed driving. Some models have a so-called tap-up function that slightly increases the speed of the M car when the driver momentarily activates the set switch while driving at a constant speed. In this way, keep pressing the set switch and decelerate.
-114 is activated, it is possible to increase the speed.

達するまでの時間もかかるという欠点があった。However, with this tap-up function, the amount of increase in vehicle speed for - times is small at 1 to 51 m/h, so in order to significantly increase the vehicle speed, the set switch must be repeatedly activated by 1 t. The disadvantages are that the operation is complicated and it takes a long time to reach the desired vehicle speed.

のがある。By the way, in general, constant speed running devices for stopping surfaces are designed to automatically cancel constant speed running when the brake is operated even if constant speed running is set, in order to prevent danger. There is. Therefore, some vehicles are equipped with a resume switch in order to return the M speed to the previously stored target speed.

とを構成の要旨とする。In order to achieve the above object, a timer circuit that operates for a predetermined period of time in response to a resume switch operation while the vehicle is running at a constant speed, and an acceleration signal generator that generates an acceleration signal in response to a resume switch operation while the timer circuit is operating. The gist of the configuration is that if the resume switch is operated again while the timer circuit is operating, an acceleration signal is generated and the speed of both is increased.

達成できる。With the above configuration, when the driver wants to increase the speed while the vehicle is running, he or she must first press the resume switch, then press the resume switch to start increasing the speed, and while the resume switch is pressed, the driver will not increase the speed. If the resume switch is released when the desired speed is reached, the vehicle can resume constant speed driving at the current speed, achieving the initial objective.

い。Next, the output of the comparator CM is integrated by the resistor 1o and the capacitor C2, and the output is fed back through the resistor 111 to the memory capacitor C of the memory circuit. As a result of this feedback, for example, the speed decreases, and while the control solenoid SL1 is energized, the voltage of the integrating capacitor C2 gradually rises, causing the voltage to rise.
In addition to the vehicle speed voltage VV which is the actual vehicle speed via A%11,
Since the voltage is applied to the memory capacitor C1, a signal indicating that the vehicle speed has increased is output before the vehicle speed voltage VV reaches the memory 1 voltage VM, which is the target speed, and the acceleration is suppressed. Never accelerate too much beyond the speed.

ＳＷ。The flip-flop circuit 7o normally maintains the output terminal of the control 71 at the #H# level and the output terminal of the Nant gate 72 at the 'L level. At this time, if the cancel switch SvI3 is closed, the state is reversed, the output ring of the Nantes gate 71 becomes I(, level), the output terminal of the Nantes gate 72 becomes IHI level, and the non-inverting input of the comparator CM becomes to 'L' level and T to 5,
The charge of the integrating capacitor C2 is Mm. Furthermore, the power amplifier 80 is turned on, the release solenoid SL is connected, and the throttle valve is released. Due to this, constant speed running is canceled. After that, release Q again
If you want to run at a constant speed of n, press the resume switch SW.

0 timer circuit 91 operates for a predetermined period of time. If the resume switch SW2 is not closed again during the operation of the timer circuit 91f'1E, the vehicle speed described in n11 is restored to the speed of the release iT. Also, when the resume switch ""'2 is closed again and fJ is performed while the timer circuit 91 is operating, the timer circuit generates an 'L' level signal, and the output of the OR gate 92 becomes 'L# level'.
The output of the gate ≦)2 is fed back to the gate G of the timer circuit 91, and all outputs of the timer circuit 91 G; J'L' are held. Therefore, while the resume switch SW2 is closed, the output of the OR gate 92 remains at 'l, + level. This 'L level signal is the die word D2. "J3
The capacitor C2 is connected to the base of the transistor T1 through the capacitor C2. Therefore, the transistor T1 is turned off and the FET Fl is turned on, so that the base level vr is applied to the base of the FET F2. Suqwachi, Frn

:>Vr, the output of the comparator C1v1 becomes zero, and the control solenoid SL1 of the actuator 5o is turned on, increasing the throttle opening and accelerating. This acceleration is achieved by using the resume switch SW.
2, it continues until the desired speed is reached, and at this point, the resume mode Sh is opened.The set signal is obtained by turning on the transistor T1 from OFF, and the vehicle speed is memorized again and the vehicle runs at a constant speed. Move to. At this time, the capacitor is discharged via the 2kl diode D3 to prevent excessive feedback from being applied during the storage.

When J is reached, the flip-flop circuit 70 turns 141, the constant speed running is canceled, and the output of the safety circuit OR gate 100 becomes 'L' to maintain this state. Therefore, the cancel switch SW3 is opened, and the six-flip flop circuit 70 maintains the state in which the erratic flight is canceled. This state (well, it continues until the resume switch SW2 becomes between the two ears).For this reason, even if the resume switch SW2 remains closed during constant speed driving and does not return,
By closing the cancel switch SW3, which was the case in the past by either driving at a constant speed or canceling it, you can prevent the danger of not being able to stop accelerating.
