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.

Several models have been proposed, but their basic configuration is a set vehicle speed set by a speed command signal supplied based on the driver's desired vehicle speed, and the actual vehicle speed (e.g. the actual vehicle speed). Based on the compared output, a speed increase or deceleration signal is supplied to the actuator of the throttle valve drive system, and this actuator adjusts the opening of the throttle valve. It is something to do.

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 signal continues to be output, it is possible to enter the constant speed driving state once using the signal from the constant speed driving command section, and only when the movement cancellation command signal is input will the abnormality be detected. 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.

In a vehicle constant speed running device equipped with a constant speed running device, if the power supply circuit of the drive system that drives the throttle valve fails in a conductive state and the conductive state is not released, constant speed running is started by operating a constant speed running start switch.

5b is welded) is a constant speed travel prohibition circuit that prevents constant speed travel. This constant speed running prohibition circuit 20 includes a start-up reset circuit 21 that outputs a pulse signal of a constant width when the ignition switch 2 and main switch 3 are on;
Two types of release signals are input: the output signal of the start-up reset circuit 21 and the release signal from the release signal generation circuit 5 that generates a release signal by operating the brake, etc., and when either one is at the Hi level, the release signal is set to Hi level. When a Hi level is output from the output OR circuit (OR) 22 and the OR circuit (OR) 22, the output Q

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, the two inputs of the OR circuit (OR) 22 are turned on. One becomes Hi level, and the R input terminal of the constant speed running determination circuit 23 becomes Hi level. For this reason,
The output of the constant speed running discrimination circuit 23 is Q=Lo level,
Q = becomes Hi level.

It's getting to the level. For this reason, an AND circuit (AND
-1) The inputs of 25 are Hi level and Lo level, respectively, and the output is Lo level. and,
One of the inputs of the AND circuit (AND-2) 27 is connected to the output of the AND circuit (AND-1) 25 via the NOT circuit (NOT) 26.

2) Both inputs 27 become Hi level, and the S input terminal of 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 = Lo level, the switching transistor 16 is turned on, and the control valve drive power supply relay 15 is activated, and at the same time, the AND circuit ( One input of AND-1) 25 becomes Low level. Furthermore, when the relay 15 is turned on, the power supply detection circuit 24 for driving the control valve
The output of the AND circuit (AND-1) 25 becomes a Hi level, but as mentioned above, one input of the AND circuit (AND-1) 25 is a Lo level, so its output maintains a Lo level and the NOT circuit (NOT) 26 is Since one input of the AND circuit (AND-2) 27 is at Hi level, it does not interfere with the input of the running start signal supplied when the constant speed running start switch 6 is turned on. , and the output from the constant speed running start signal generation circuit 7 at this time is stored in the set vehicle speed storage circuit 1.
0, the memory circuit is activated and the set vehicle speed is stored.

である。 On the other hand, if the power supply relay 15 for driving the control valve is abnormal (that is, remains on) due to welding, etc., when constant speed driving control is not being performed, that is, when the constant speed driving determination circuit 23 is at = Hi level. When the output of the control valve driving power supply detection circuit 24 becomes Hi level, the output of the AND circuit (AND-1) 25 becomes Hi level, and the NOT circuit (NOT) 26
One input of the AND circuit (AND-2) 27 that has passed through becomes Low level. In this state, even if the constant speed running start switch 6 is turned on and the output signal from the constant speed running start signal generation circuit 7 becomes Hi level, the output of the AND circuit (AND-2) 27 remains at Low level. be. 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 cut off the constant speed running signal. Therefore, this signal becomes invalid, making it impossible to store the vehicle speed in the set vehicle speed storage circuit 10, making it impossible to drive at a constant speed, which is extremely safe.

In a vehicle constant-speed running device equipped with a drive system that drives a valve, if the power supply circuit of the drive system that drives the throttle valve fails in a conductive state and the conductive state is not released, constant-speed running is started. The configuration includes a constant speed driving prohibition circuit that disables constant speed driving by disabling the constant speed driving start signal by operating the switch and making it impossible to store the vehicle speed in the set vehicle speed storage circuit. When you try to start constant speed driving by operating the high speed driving start switch, if the power supply circuit of the throttle valve drive system is in a conductive state and fails and the conductive state is not released, for example, the power supply for driving the control valve If the supply relay remains on due to welding or other causes and is malfunctioning, the constant speed driving start signal sent by operating the constant speed driving start switch is cut off midway and invalidated. By disabling vehicle speed storage in the set vehicle speed storage circuit, constant speed driving cannot be started, which provides an extremely excellent effect of realizing safer vehicle operation.
