きるという利点がある。(Prior art) A constant speed traveling device for a vehicle is capable of automatically controlling the vehicle speed to a constant speed after setting the desired vehicle speed while driving the vehicle without having to operate the accelerator. This is a device that allows you to do this. This constant speed traveling device has the advantage that it can reduce driver fatigue and reduce the fuel consumption of the automobile when continuously driving at a constant speed on well-maintained roads such as expressways.
従来、この種の車両用定速走行装置としては、いくつか
の型式のものが提案されているが、その基本となる構成

ュエータによってスロットルバルブの開度を調整するも
のである。In the past, several types of constant-speed traveling devices for vehicles have been proposed, but their basic configuration is based on a speed command signal supplied based on the vehicle speed desired by the driver. The set vehicle speed is compared with the actual vehicle speed of the vehicle (for example, a vehicle speed voltage supplied based on the actual vehicle speed), and based on the compared output, a speed increase or deceleration signal is supplied to an actuator of a throttle valve drive system. This actuator adjusts the opening degree of the throttle valve.

よって一度は定速走行状態にすることが可能であり、そ
の後解除指令信号が入力された時にはじめて異常を検知
することとなり、それゆえ安全回路の一部に異常がある
時でもいったん定速走行させた後に解除指令信号が入る
までは検出できないという問題点を有していた。In such conventional constant speed traveling devices, the control system outputs a signal to cause the vehicle to travel at a constant speed at the set vehicle speed according to the difference between the set vehicle speed and the actual vehicle speed, and a release command is issued from the release command section. The configuration includes a calculation unit that determines that there is an abnormality and outputs an abnormal signal when the above-mentioned constant speed driving signal is output even though the vehicle is running at a constant speed. Even if the condition is such that the signal continues to be output, it is possible to enter the constant speed driving state once by the signal from the constant speed driving command section, and then the abnormality is detected only when the release command signal is input. Therefore, even if there is an abnormality in a part of the safety circuit, it cannot be detected until a release command signal is input after the vehicle is driven at a constant speed.

路（ＡＮＤ−２）２７とから構成されている。Furthermore, 20 is a power supply circuit (15) for the control valve 13 as a drive system for driving the throttle valve.
This is a constant speed travel control circuit that prevents constant speed travel when the relay 15 is in a conductive state and is malfunctioning (for example, when the contact 15b of the relay 15 is welded). This constant speed running control circuit 2o
is ignition switch 2 and main switch 3
a start-up reset circuit 21 that outputs a pulse signal of a constant width when is on, the output signal of the start-up reset circuit 21, and the release signal generation circuit 5 that generates a release signal by operating a brake or the like. an OR circuit (OR) 22 that inputs two types of signals and outputs a Hi level when one of them is at a Hi level; and the OR circuit (OR)
When Hi level is output from 22, the output Q terminal is set to Lo level, the Q terminal is set to Hi level, and the constant speed running start signal is set to H.
When the i level is input to the S input terminal, the output Q terminal becomes Hi.
level 2 and sets the Q terminal to Lo level; and a control valve drive power source that detects whether or not the control valve drive power is being supplied and outputs Lo when it is not supplied. The detection circuit 24, the Q output of the constant speed running determination circuit 23, and the output of the control valve driving power supply detection circuit 24 are input, and when both are at Hi level, the output is H.
an AND circuit (AND-1) 25 that outputs the i level;
The constant speed running start signal from the constant speed running start signal generation circuit 7 and the signal obtained by inverting the output of the AND circuit (AND-1) 25 by the NOT circuit (NOT) 26 are input, and both are at Hi level. It is composed of an AND circuit (AND-2) 27 that sometimes outputs a Hi level.
次に、上記した回路構成の動作について説明する。Next, the operation of the circuit configuration described above will be explained.

レベル、Ｑ＝Ｈｉレベルになる。First, when the ignition switch 2 is turned on and the main switch 3 of the constant speed running device is turned on, when the output of the startup reset circuit 21 becomes Hi level, one of the two power circuits of the OR circuit (OR) 22 is turned on. It becomes Hi level, and the R input terminal of the constant speed running determination circuit 23 becomes Hi level. Therefore, the output of the constant speed running determination circuit 23 is Q=Lo
level, Q = Hi level.

になる。On the other hand, when the control valve drive power supply relay 15 is normal and the vehicle is not traveling at a constant speed, the relay is off, so the output of the control valve drive power supply detection circuit 24 is at Lo level. It has become'. Therefore, the inputs of the AND circuit (AND-1) 25 are Hi level and LO relay, respectively, and the output is LO relay. One of the inputs of the AND circuit (AND-2) 27 is connected to the AND circuit (AN-2) via the NOT circuit (NOT) 26.
Since it is connected to the output of D-1) 25, it becomes Hi level.

As a result, the S input terminal of the constant speed running control circuit 23 becomes Hi level. As a result, the output of the constant speed running determination circuit 23 becomes Q=Hi level and Q=Lo level, and the switching transistor 16 is turned on.

を作動状態として設定車速を記憶する。At the same time as the power supply relay 15 for driving the control valve operates, one input of the AND circuit (AND-1) 25 becomes LO.
Become a riller. Furthermore, when the relay 15 is turned on, the output of the control valve drive power supply detection circuit 24 becomes Hi level, but as mentioned above, one input of the AND circuit (AND-1) 25 is the LO relay. , its output maintains the LO rerel, and one input of the AND circuit (AND-2) 27 through the NOT circuit (NOT) 26 is at Hi level, so it is supplied when the constant speed running start switch 6 is turned on. This does not interfere with the input of the travel start signal. The output from the constant speed running start signal generation circuit 7 at this time is input to the set vehicle speed storage circuit 10, and the storage circuit is activated to store the set vehicle speed.

Therefore, even if the constant speed running start switch 6 is turned on and the constant speed running start signal is input, if the relay 15 is abnormal, the AND circuit (AND-2) 27 will output the constant speed running signal and the circuit will be disconnected. , this signal becomes invalid, making it impossible to drive at a constant speed, making it extremely safe.

In a vehicle constant speed running system that is equipped with a drive system that drives a throttle valve, when the power supply circuit of the drive system that drives the throttle valve is in a conductive state and has a failure, the constant speed drive start signal is disabled and the constant speed drive system is maintained. Since the configuration is equipped with a constant speed cruise control circuit that prevents high speed driving, if the power supply circuit of the throttle valve drive system is in a conductive state and malfunctions when trying to start constant speed driving, for example, the control If the power supply relay for driving the valve is stuck on due to welding or other causes and is malfunctioning, the constant speed driving start signal is cut off midway and becomes invalid, making it impossible to start constant speed driving. Therefore, a very excellent effect of realizing safer vehicle driving can be obtained.
