Abstract

PURPOSE:To reduce overshoot in a constant speed running device for an internal combustion engine with a supercharger, by making gain of a control system variable from an end of operation of an automatic accelerating switch till a timing when the engine escapes from a high output area. CONSTITUTION:A brake switch is closed in response to operation of a brake pedal, and a cancelation signal is fed to an output signal generation circuit 160. The output signal generation circuit 160 receives the cancelation signal most preferentially, and stops application of an electromagnetic clutch connection signal, simultaneously supplying a deceleration signal to a drive circuit 250 continuously. The drive circuit 250 cuts off current to a coil incorporating a worm wheel of an actuator 10, and accordingly an electromagnetic clutch plate is released. As a result, a throttle valve is instantaneously returned to a minimum opening degree by a return force of a throttle link to effect safe deceleration.

When the count value of the second clock signal of the output 8-digit generating circuit 160 reaches the count difference e, the application of the speed increase signal to the drive circuit 250 is stopped at the same time as the count of the second clock signal ends. . Therefore, for a time of ε/f2, the speed increase signal is applied to the drive circuit 25.
0, and a correction signal proportional to the speed deviation can be issued. The drive circuit 250 receives the speed increase signal and causes the DC motor 11 of the actuator 10 to rotate forward. As a result, the rotation of the motor 11 is decelerated by the deceleration mechanism 12, and as the sector plate 14 rotates, the opening degree of the throttle valve 3 increases and the vehicle speed increases.

Then, there is a large overshoot, etc.; 1, so as described below, in 2+ , Until the high output state of the 4-person 1'J port is released, the deceleration f111 of the control gear 1 (gain switching) is performed and the throttle valve 3 is closed at all points. Pressure detection by the high output detector 50 Circuit 5] iJ When the preset high output detection lower limit pressure is exceeded, it is applied to the clock switching circuit 210. It is preferable that the output output detection lower limit is given up after detecting the full engine speed of the internal combustion engine 1. However, there is no practical problem if the rear rotation speed detection is omitted and the engine speed remains constant regardless of the engine speed.By the way, when the high output state of 75 rpm is reached as described above, if the automatic acceleration switch 60 is opened, The output signal generation circuit gives the same deceleration signal as the previous Ht2 to the drive circuit 250, but the clock switching circuit 210 causes the clock switching circuit 21 to
When the output of the high output detector 5υ is applied to 0, the automatic acceleration switch 60'k rjll is applied and the deceleration signal 0 is applied only to the clock switching circuit 210 until the high output detector stops. As a result, the second clock signal generation circuit 220 is switched to the third clock signal generation circuit 230. Here, if the third clock frequency is set lower than the second clock frequency, the driving circuit as described in n11. 250
The deceleration signal applied to the drive circuit 1 takes a long time, and
The DC motor 50 of the actuator 10 is rotated σ in the reverse direction for a long time, and the throttle valve 3 is quickly operated in the closing direction, so that the high output of the internal combustion engine 1 can be quickly reduced to the normal output 1. When the constant speed traveling device is released (3/), this is achieved by operating the vehicle's brake pedal. In response to the operation of the brake pedal, the on-rake switch 4J is closed and
The cancellation signal is applied to the full output signal generation circuit 160.

Therefore, the throttle valve 3 returns instantaneously to the small opening groove J'1) by the return force of the throttle link 8, allowing safe VC deceleration. In the above embodiment, the set switch 30 and the automatic acceleration switch 60 are separated, but each 2-inch switch is made up of 1,111 identical switches, and the set signal and the switch F correspond to the operation time. Even if the configuration L7 is such that all automatic acceleration instruction signals are generated, the same effect as in the above embodiment can be obtained. [Effects of the Invention] As described in detail above, the vehicle stability system of the present invention is capable of controlling the upper IL when the automatic acceleration switch is fully operated and the supercharged internal combustion engine reaches a high output state. Output letter indicating whether it is an internal combustion engine! In order to escape from the circle in 1, the gain on the deceleration side of the control j thread is increased to speed up the operation of the throttle valve, so automatic acceleration with less overshoot can be achieved.

Claims (1)

[Claims] a vehicle speed detecting means for generating a vehicle speed signal in response to the traveling speed of the vehicle; a set vehicle speed storing means for causing the vehicle to travel at a constant speed at a desired set speed; and an actual vehicle speed from the vehicle speed detecting means. control signal generating means for comparing the set vehicle speeds in the set vehicle speed storage means and generating either a speed increase signal or a deceleration signal in response to the speed deviation; Means for controlling the opening degree of a throttle valve installed in an intake pipe of a vehicle internal combustion engine in response to an acceleration signal or a deceleration signal sent from an illumination signal generating means, and an automatic acceleration instruction for instructing automatic acceleration driving. means, and in response to the instruction signal of the automatic acceleration instruction means, the Oki shorthand 1
．． means for automatically accelerating control signal generating means for generating a control signal for increasing the total vehicle speed, and a flit equipped with a supercharging material.
When the internal combustion engine for vehicle departure exceeds a predetermined output, it generates a VC high output (M number) and automatically accelerates the vehicle at 3F.
